Just had this "teal screen of death" scare tonight when downloading the latest OS update. Video instructions still relevant and works as of Dec 2021! Thank you so much!!
Legendary instructions. I knew Odin, but Frija and finding the carrier code for a phone that bricked mid update was solid. 5 stars! Love the step-by step and commentary on points to wait at, always frustrating when you think its frozen again. Thanks!

You're an amazing legend. Tried to install a custom ROM on my S20 FE 5G but all of them were BS. Managed to install a stock ROM using odin and after relocking my bootloader now i got my stock ROM back along with 95% of the features it has, including OTA updates and play certificate without magisk! the only issue though was the Knox related apps but I don't really use them anyways. Thank you so much for saving my phone, I do owe you everything
I don't know if it's too late to ask, but what website did you use to download the stock android firmware? I'm stuck with a custom rom that doesn't receive updates and it suck for me
Amazing!!! Thank you so very much! Like the others before me, you saved me from having to buy a new phone. You helped where Samsung couldn't...or is it wouldn't. One additional step that I needed to do was to get a new SIM card as the phone would not re-activate with my carrier (Verizon). Not sure why. But 5 minutes in the Verizon store and all good. Thanks again. (May 30, 2023)

My Samsung Galaxy S21 Ultra 5G was working very well with the Christmas decorations on there. I received a text message from a female hacker saying: I got your number and i hacked your phone. Few minutes later my phone started to act very strange than it got stuck on the boot loop. I went into the Android recovery mode to wipe out the partition than I get an error message at the bottom of the screen saying: [ libfs_mgr ]Error updating for slotselect. I select "Reboot system now" than my phone still were stuck on boot loop 😟 Can somebody please help me ? 😨 and is it because it was hacked ? 😨 I am crying 😰
Hi, My S21 is stuck on pin unlock. Its the right pin but there is a bug that immediately locks the device. How can I get around this without a factory reset? Deleting Cache partition has done nothing, can bootloader help me?
possibly no. android has china restriction level, once something happens you're bound to be screwed. in a pc you could bypass a pass easy by hacking it in android, hacking it can mess up the device. happened to me once and had to factory reset
any solution for the spinning dots after bootloop? I already soft reset, wiped cache, optimized apps, charged phone (doesn't show up on pc), and reflashed odin3...trying to save photos my son didn't backup (storage full)

Great vid! This method is basically wiping the old system files and flashing new ones? Or does it just repair the previous instance? Will i still be able to recive updates after i do that?
correct. it's taking a freshly downloaded copy of the firmware and overwriting the partitions on the phone with the firmware this video wipes the data (not a repair), and you should still be able to receive OTA updates like normal join our daily Android discussions if you have more detailed questions ruclips.net/channel/UCnowc_KHgjVNj3Y-E-oQ8awjoin

Hello I have one question and I would like to know if you can me. I have on my s21 ultra phone the latest firmware from verizon which is G998USQU5CVG9 and it want to flash the latest SM-G998U1 XAA firmware which is G998U1UES5CVF5. Is it safe? Or would this be considered a downgrade. Thanks again for your help.
Hello sir. I've already watched a few of your videos regarding flashing a Samsung but I've got 1 question I'm stuck with. The thing is I got myself an S20+ with the newest firmware and Android13. The person that gave me it said around half a year ago after an update happened 2 green lines appeared. I know this is now a pandemic on Samsung devices (and not only) where half of them get the green lines after software updates but both Samsung and experts claim it's a hardware defect (just that no one tries to explain it was caused by software). Most likely the LEDs or transistors got burned. I wanted to try reverting it to Android 11 or 12, but after looking through RUclips I've noticed some people say you can't flash the newest Samsungs with a different binary version firmware. But if we look on firmware websites, most firmware has different binaries (like 2 versions of the same binary so you can only downgrade the latest one). Will it flash properly with different binaries or will it brick the phone? That's the question after such a long intro xD
Thanks for the reply. Thought so, since after hours of googling and different videos notices some people saying binary version needs to be the same, however S20 practically for every version has a different binary. Welp, thanks anyway.
Can you please show is how to remove 5g and revert to 4g , they have taken away all of our options to do so. We can't even change the band setting anymore. I have a Motorola g stylus 5g 2022

hard brick - serious situation. most new phones are designed PURPOSELY to be useless once they get bricked. you must have balls of luck to get them back and even tech guys couldn't bring then to life. my s20 was bricked a month ago and they still havent fixed it, it's sad that samsung is making so fragile phones
@@XBGamerX20 hey man, thanks for the reply! Unfortunately my phone was a complete goner, because, as you said, it was a hard brick BUT i was able to get it replaced since it was still covered by warranty, so if you've had similar problems i'd suggest you try to get a replacement from samsung
@@yikes8707 ik. my phone had a troubling past sadly tho and the warranty was voided after attempts to root it and bricking problems were quite a phenomenon for me but this time the entire bootloader crashed. I'm possibly facing a hard brick as well but hopefully samsung fixes their newer phones, it's sad they're so epic and powerful but yet hard to to fix
Related but not exactly, i have an unlocked S21Ultra, i used odin to flash to the standard SAMSUNG Firmware in the UK. BTU' but the phone still displays 'Three mobile' Firmware (a Uk carrier)... has something changed with the Flash process that no longer allows for full Samsung Firmware Flash, i used the standard CSC file not the Home one... any thoughts related to this appreciated, even my local phone unlock company scratched his head at this one.
you may be able to, but it depends on how bad the bootloop is. using the home csc file is something I would try first in an attempt to save my data as well, so I do recommend you try it
@@ExplainingAndroid I tried no fix. Can try downgrading a security patch? My problem: phone starts up and goes to the second samsung logo and gets stuck for few minutes and restarts. (After uninstalling an app I restarted the phone. Then it got stuck on this problem.)
My S21 Ultra (SM-998B THL) is facing with reboot problem. Then I try to flash my phone by using the lasted firmware from Samfirm. On the process of Odin (v3.14.4), It is stuck on prism.img. I try to use both CSC and Home CSC and It does not work for me, pls help me what to do next :(

hey everything went off smoothly ,even it said pass on odin and then auto rebooted but its still stuck on bootlogo.Instead of just putting the firmware files to 4 different places I simply added the file to AP and the process went on smoothly but still I am facing this issue,plz help
Magisk developer advises against flashing just the AP file. It's actually a common culprit of slashing total capacity of phones (from say, 128GB to 32GB or something) I'm not sure why you would be getting that bootloop when flashing four files. It doesn't happen to me (as shown in the video) so I'm thinking there could be an issue with your download. Have you tried re-downloading a fresh copy of the firmware so you know you aren't having any corruption issues? let me know if this helps ruclips.net/channel/UCnowc_KHgjVNj3Y-E-oQ8awjoin
@@ExplainingAndroid yeah ,actually after looking all over the Internet I realised these firmwares are hard to get ,I even subscribed to sammobile but the speeds are awful and in case of frija just after a couple of minutes the speed drops to zero and yeah the firmware I flashed was just a .TAR file that I added to AP and the process went well but it seems it was a fake firmware that messed up my device.The good part is I have my twrp recovery installed ,I am now only waiting for a good source to download the firmware,do you know any?
Hi i cant enter en download mode o recovery mode, its stuck un firsts samsung screen, i use volume down and power it vibrates powers down and inmediatly goes to samsung screen again any help please please
@@ExplainingAndroid it was saying (write) operation failed or something like that. It seems to have worked now and passed checks. But when the phone turned back on, it's asking for the pin code or google account information and I've forgotten them. Is there any way I can bypass these?

hello, i just upgraded to 6.1 in the s21 ultra, having the SM-G998U1 and the touchscreen is totally unresponsive, its been like this for hours. Is this guide gonna help me get back to the previous 6.0 oneui android 14 firmware?
My phone has been restarting randomly throughout the day like I could be changing a song and my phone decides to have a seizure and restart over and over again
sounds like the OS is getting quite buggy. have you tried a factory data reset? or flashing a freshly downloaded copy of the firmware via Odin (the second suggestion wouldn't require erasing all of your data)
My S21 Ultra is stuck in continuous boot loop until it dies. You can't stop it or reboot it. It gets to the 2nd Samsung screen then shuts down for 20sec then starts back up on its own over and over. Only thing I can do is get to the Download Mode Menu. My main concern is I didn't realize the my cloud was full and so have lost some precious photo/videos. Is there anyway I can recover these?
nope just tried for samsung s20. it got bricked and ended up deleting 1000+ files, which in turn left it bricked. delivered to tech shop, havent fixed it for a month now. it's sad that samsung is making fragile phones
@@XBGamerX20 yes it is! I feel that they should have recall the s20/s21 completely or replaced all the ones with issues free of charge. I did have extended warranty through Telus, but it cost me $450 deductible because my phone was over a year old (14months) 😢. They wouldn't even replace it with a s21 Ultra becuz of the amount of issues that phone had. They sent me a s22 Ultra instead. I was pretty upset I had to pay anything. The s22 is nothing special. The camera is awful compared to the s21.
@@cd6691 can confirm. the s21 is too worse than s20, like they have everything the same but no memory card slot. and the 1080p instead of 1440p in s20. only good for the s21 is that they have a plastic back and equipped with android 11, which is 2 things I hate in s20. still mine had a troubling past and the warranty was voided cause of failed rooting attempt and here we are, breaking for the 4th time. and this time it's possibly dead. I'd only be glad for samsung to fix their motherboard systems because we cant throw away $700 phones when their bootloader decides to die or wait weeks to get a new phone and samsung is perhaps among the few phones with the best ui. thing is, I'd have to go for samsung s21 probably because the s22 is the most messed up s series phones I've seen, tbh s21 looks far better than s20 in terms of external visuals/aesthetics
@@XBGamerX20 yeah no memory slot was awful! I wish I could have got a S21 replacement but they are not selling it in my area anymore becuz of the issues. I have 9 months left on my contract then I will be looking into a phone from a different company. It's disappointing what has happened to Samsung. My S6 still works great tho.
@@cd6691 true man. I have a samsung j5 and the amount of times I had switched to this cause the previous s models I had reached a great number. this j5 got bricked 2 times but fixed it in no time using stock rom, the s20 got bricked 4 times and required tech support in all of the cases. s20s were highly problematic, hopefully the s30 series brings a new generation in the future. it's sad that samsung is losing customers because their new phones are so powerful yet so fragile.
Better idea: dump Samsung and go to a different brand. It's stupid that they don't have you plug it into your computer and PICK the source content by looking up your IMEI number. Very bad way to do it. It bricked my phone and I got a message saying the phone HAS to receive the download. I tried to skip and it forced it anyway. The dumbest part? If weather interrupts the signal, you're screwed. Samsung is getting worse every time. And their S21 phones do not impress me, especially the menu layout, which makes it difficult to find certain settings.
@@sulxanberize9361 probably more difficult. unless you bought it in China (maybe one or two other countries) then you can't unlock the bootloader through official methods XDA promotes a paid service, but it costs 100+ dollars and not something I can vouch for or recommend (since it isn't official and uses shady methods)
my phone was completely busted. I left it charge till it was in recovery mode than did the factory reset and it worked. im sobbing right now. You saved me from having to buy a whole new phone. thank you thank you thank you.

I'm possibly facing a hard brick as well but hopefully samsung fixes their newer phones, it's sad they're so epic and powerful but yet hard to to fix
gt-p5110 Samsung galley tab2 10.1 won't hard reset ..stuck in bootloop
thanks for the information but my phone samsung m21 stops at super for ours, what can I do?
Related but not exactly, i have an unlocked S21Ultra, i used odin to flash to the standard SAMSUNG Firmware in the UK. BTU' but the phone still displays 'Three mobile' Firmware (a Uk carrier)... has something changed with the Flash process that no longer allows for full Samsung Firmware Flash, i used the standard CSC file not the Home one... any thoughts related to this appreciated, even my local phone unlock company scratched his head at this one.
Can we use home csc to fix boot loop issues without data loss?
you may be able to, but it depends on how bad the bootloop is. using the home csc file is something I would try first in an attempt to save my data as well, so I do recommend you try it
@@ExplainingAndroid I tried no fix. Can try downgrading a security patch?
My problem: phone starts up and goes to the second samsung logo and gets stuck for few minutes and restarts. (After uninstalling an app I restarted the phone. Then it got stuck on this problem.)
How can I get my CSC code for the frija firmware files if the phone is stuck in that loop and I can't boot it?
My S21 Ultra (SM-998B THL) is facing with reboot problem. Then I try to flash my phone by using the lasted firmware from Samfirm. On the process of Odin (v3.14.4), It is stuck on prism.img. I try to use both CSC and Home CSC and It does not work for me, pls help me what to do next :(
After a successful odin reset my Samsung sm-t585 is not booting
I just want to ask a question 😐
Can I trade or upgrade both of the Samsung Galaxy S21 Ultra 5G and Samsung Galaxy S 10+ to Samsung Galaxy S22 Ultra if they are both broken ?
My phone turns on but then it just wont tap anywhere
Firmware will take 7-8 hours to download from the website to my computer according to my computer.., anyone else's computer said this?
Couldn't get my s21 ultra to work, it keeps bootlooping whenever it likes to, any solution?
Odin is stuck for me at SetupConnection?

hey everything went off smoothly ,even it said pass on odin and then auto rebooted but its still stuck on bootlogo.Instead of just putting the firmware files to 4 different places I simply added the file to AP and the process went on smoothly but still I am facing this issue,plz help
Magisk developer advises against flashing just the AP file. It's actually a common culprit of slashing total capacity of phones (from say, 128GB to 32GB or something)
I'm not sure why you would be getting that bootloop when flashing four files. It doesn't happen to me (as shown in the video) so I'm thinking there could be an issue with your download. Have you tried re-downloading a fresh copy of the firmware so you know you aren't having any corruption issues?
let me know if this helps ruclips.net/channel/UCnowc_KHgjVNj3Y-E-oQ8awjoin
@@ExplainingAndroid yeah ,actually after looking all over the Internet I realised these firmwares are hard to get ,I even subscribed to sammobile but the speeds are awful and in case of frija just after a couple of minutes the speed drops to zero and yeah the firmware I flashed was just a .TAR file that I added to AP and the process went well but it seems it was a fake firmware that messed up my device.The good part is I have my twrp recovery installed ,I am now only waiting for a good source to download the firmware,do you know any?
Hi i cant enter en download mode o recovery mode, its stuck un firsts samsung screen, i use volume down and power it vibrates powers down and inmediatly goes to samsung screen again any help please please
got the partition super on my ultra s21+. Before attempting Oden and wipe data, is there an option to get the data
When you click start, is there a progress bar I can watch? or do i just wait until something happens eventually?
Hello may i ask. if i do this return to stock Firmware the boot loader will lock again? hope you reply thanks
no, following this tutorial will not relock the bootloader. it will just put the original firmware back on your phone
what do i do if it force boots into download mode and i cant leave it
I keep getting 'Fail' when trying to flash files in Odin. Can anyone help please?
what's the full error say in the Log window of Odin?
@@ExplainingAndroid it was saying (write) operation failed or something like that. It seems to have worked now and passed checks. But when the phone turned back on, it's asking for the pin code or google account information and I've forgotten them. Is there any way I can bypass these?

My Samsung Galaxy A515f TPA region Panama just shut down while on Facebook then ever since it's in bootloop so I don't know what firmware was in it previously. Please help . Can I just find firmware with CSC region Panama with Android 12 . I just want it to work again
Volume down + power always brings me back to the blue download screen. What can I do, no chance to access the menue...
I’d like to know the same thing
So i had my latest update on my samsung s21+ ultra and after downlaonding and installing the update it restarted and then got me into downloading green screen and i tried the combination of power button and volume down but it keeps taking me to the green screen with download.Does anyone know how to deal with this ? it shows the screen on 7:56 but in the corner says "Odin mode (SVB Failed)
Super: Build id does not match with the reference. I don t know what to do
Will this help with the black screen of death?
When I press start, it appears instead of pass vbmeta s21 ultra
I thought your number might do, but it doesn't show either.
Hola como estas? Tengo un Samsung s21 modelo SM-G9910 cuando entré a la página samfw los únicos firmware que aparecen son China, Taiwán y Hong Kong, lo cual el mio aparece con un firmware chino y me está trayendo problemas. No puedo bajarme otro modelo, como el SM-G991U que es de EEUU o que opción me recomiendas? que baje el Hong Kong que tal vez funcione mejor?
will this void the warranty if i flash a new official samsung firmware?
thanks it worked well with my zflip luckly
That's great to hear :) I appreciate you taking the time to share this information about the zflip

Is there any option to switch firmware version by using this Method???
For Example- SM G998N to SM G998B
Hello brother my s21 is restarting by itself i did the reset and the safe mode and all the solution and it still restarting should i do the firmware?
Did you find ! Solution for this
hello, i just upgraded to 6.1 in the s21 ultra, having the SM-G998U1 and the touchscreen is totally unresponsive, its been like this for hours. Is this guide gonna help me get back to the previous 6.0 oneui android 14 firmware?
Hopefully lol I'm doing it now
Did this work?@@iitsMKC
My phone has been restarting randomly throughout the day like I could be changing a song and my phone decides to have a seizure and restart over and over again
sounds like the OS is getting quite buggy. have you tried a factory data reset? or flashing a freshly downloaded copy of the firmware via Odin (the second suggestion wouldn't require erasing all of your data)
The only thing I've done to it was a factory reset, and it worked for a couple of days, and then it came back.
I did the flashing today so ima see if it works
Didn't work 😪
@@dr3azy I have the same problem and i can't fix it with factory reset.
Where can i find the files for my firmware
Thank you so much!!!!!!!!!!!!!!!!!!!!!!
you're most welcome :)
My S21 Ultra is stuck in continuous boot loop until it dies. You can't stop it or reboot it. It gets to the 2nd Samsung screen then shuts down for 20sec then starts back up on its own over and over. Only thing I can do is get to the Download Mode Menu.
My main concern is I didn't realize the my cloud was full and so have lost some precious photo/videos. Is there anyway I can recover these?
nope just tried for samsung s20. it got bricked and ended up deleting 1000+ files, which in turn left it bricked. delivered to tech shop, havent fixed it for a month now. it's sad that samsung is making fragile phones
@@XBGamerX20 yes it is! I feel that they should have recall the s20/s21 completely or replaced all the ones with issues free of charge. I did have extended warranty through Telus, but it cost me $450 deductible because my phone was over a year old (14months) 😢. They wouldn't even replace it with a s21 Ultra becuz of the amount of issues that phone had. They sent me a s22 Ultra instead. I was pretty upset I had to pay anything. The s22 is nothing special. The camera is awful compared to the s21.
@@cd6691 can confirm. the s21 is too worse than s20, like they have everything the same but no memory card slot. and the 1080p instead of 1440p in s20. only good for the s21 is that they have a plastic back and equipped with android 11, which is 2 things I hate in s20.
still mine had a troubling past and the warranty was voided cause of failed rooting attempt and here we are, breaking for the 4th time. and this time it's possibly dead. I'd only be glad for samsung to fix their motherboard systems because we cant throw away $700 phones when their bootloader decides to die or wait weeks to get a new phone and samsung is perhaps among the few phones with the best ui.
thing is, I'd have to go for samsung s21 probably because the s22 is the most messed up s series phones I've seen, tbh s21 looks far better than s20 in terms of external visuals/aesthetics
@@XBGamerX20 yeah no memory slot was awful! I wish I could have got a S21 replacement but they are not selling it in my area anymore becuz of the issues. I have 9 months left on my contract then I will be looking into a phone from a different company. It's disappointing what has happened to Samsung. My S6 still works great tho.
@@cd6691 true man. I have a samsung j5 and the amount of times I had switched to this cause the previous s models I had reached a great number. this j5 got bricked 2 times but fixed it in no time using stock rom, the s20 got bricked 4 times and required tech support in all of the cases. s20s were highly problematic, hopefully the s30 series brings a new generation in the future. it's sad that samsung is losing customers because their new phones are so powerful yet so fragile.

you get this error in Odin?

Sir can you help me
Thank you
THANK YOU SOOOOOOOOOOO MUUUUUUUUCHHHHHHHHHH
Better idea: dump Samsung and go to a different brand. It's stupid that they don't have you plug it into your computer and PICK the source content by looking up your IMEI number. Very bad way to do it. It bricked my phone and I got a message saying the phone HAS to receive the download. I tried to skip and it forced it anyway. The dumbest part? If weather interrupts the signal, you're screwed. Samsung is getting worse every time. And their S21 phones do not impress me, especially the menu layout, which makes it difficult to find certain settings.
The model I have is SM-G998b s21 5gb
DID YOU FIND A SOLUTION? IM FACING THE SAME THING WITH THE EXACT SAME MODEL PHONE.
sorry about the caps . i forgot to turn the caps lock off :P
ROOT FAILED WHAT A JOKE
BROOOOO you saved my ass thanks a lot but.... i fucked my phone trying to install twrp xD
If this works, Im sending you some cash by paypal.
every little bit helps! let me know if you need my paypal address :)
I can't boot into recovery mode. It's impossible and I can't boot into the phone. I forgot passwords and pattern, I had 3 years to use it.
Turn off the phone into Safe mode by pressing and holding the OFF button.

Hello
I have s21 ultra
In developer option missing bootloader.please help(((
@@sulxanberize9361 is it an exynos one?
@@ExplainingAndroid no.snapdragon
@@sulxanberize9361 probably more difficult. unless you bought it in China (maybe one or two other countries) then you can't unlock the bootloader through official methods
XDA promotes a paid service, but it costs 100+ dollars and not something I can vouch for or recommend (since it isn't official and uses shady methods)
