Brilliant video, I just got one of my motherboards working with your guide. I'd flashed the BIOS onto a chip but didn't realise I had to edit those details. Thank you!
Super well done! This is like a week of research.
I really have to thank you for this very helpful tutorial. By your instructions i was able to repair my UEFI on my ASUS Z97-P Board. After i installed Vanguard (an anti cheat protection measure operating on windows kernel level for the recently released game Valorant by Riot) my computer was not able to display any video output or to power usb devices. my last option before buying a new board was to reflash the bios which surprisingly actually worked.
Did it got corrupted by the game
@@tdkxbalor9397 i guess the corruption happened right after i restarted my pc. After installing valorant and it prompting that i need a reboot to Initialize vanguard which i did, the pc was no longer able to boot. Just a black screen and fans spinning without any sign of life.
@@leonard_roy did you report it to the game Devs it can be serious problem if it happened due to the game
@@tdkxbalor9397 yea of course but the german riot support didnt bother. Seemed like they were too incompetent to understand the issue. Their final answer was that it simply is not possible for vanguard to corrupt a bios. I even wrote to some famous tech youtubers like ltt but never got a response. So afterwards i swore to myself to never install that bullcrap of a game ever again and thats that.
well. I just found out about your videos, but i'm already hooked. Hope to see more stuff like this in the future
Tyy
@@insanitylol youre welcome

Hi, I have 2 Intel Tablets from year 2015 with identical hardware but diferent BIOS version and I´m trying to making work the Dump from one of them to the other one without succes, I already cleaned the TXE but there is no display, What can I do?
hi where can i find an editor for asrock bios
same question
I wonder would just reseating the flash IC have worked? That type of IC socket is low quality and inclined to cause poor connections when a bit of corrosion forms between the IC legs and the socket contacts (and the IC legs did looks a little grubby). Unless the contents of the flash had somehow become corrupt, its hard to see how a previously-working motherboard would suddenly stop working in a way that would require a BIOS upgrade to repair. Still, its interesting to see the procedure - thanks.
Great point! I should have tried reseating first. If I had not already returned the computer, I would test your theory. Thanks, I will make a note on my website write-up. Regardless I would still make a backup of the existing firmware while the chip was out to ensure copies of the relevant BIOS fields.
Great video . . . my only qualm is that Windows is still on the machine. 😄
that's loud and clear, sir, thanks so much, let me share it with my friends, i have learned a lot from your channel!
how can i do some donation on your channel?
Thanks for the generous offer! I do not want to accept donations at this time because this channel is my hobby and I don’t want it to feel like a job. However, I do appreciate very much you sharing with your friends.
I have this problem so I shutdown my pc during and update and it undo the changes now I’m stuck on the UEFI bios page or it pops up with a message that reads select a proper device etc I’ve waited a day and tried almost everything on RUclips please help
It doesn’t sound like a damaged bios. It could be a lot of things but since it happened during a Windows update (I assume that is what you meant by update), it is probably a partition problem. I’d get a Windows 10 media USB drive (I assume you are using Windows 10) and try the Repair your computer option. Under System Recovery Options choose Command Prompt. Run diskpart and make sure the correct partition is activated. Afterwards run bootrec /rebuildbcd. If that doesn’t completely fix the problem, it will hopefully get you to the point where you can run System Recovery Options - Startup Repair. This is a relatively advanced repair and my suggestion is only a guess. I am not a Windows expert. You could lose data!
i REALLY need help with this in converting an asus bios update exe to a workable bin file with all the correct information. zephyrus m16 2023, can't find ANY resources with these newer laptops.
hello thanks for your useful information.
I have question what if I want flash bios without typing that information eg:- mac id,sn,suid.
Also I'm having problem not able to save new bios flash file generated by fd44 editor.
I'm using asus motherboard am4 socket.
I hope you will answer this as soon as possible.
Thanks again.
Great Instructions !
Thank you very much
Thank you and love how you kept fluff talk to a min!
How do you do this process with no access to the original bios? I accidentally wiped the bios chip before backing up the original bios unfortunately
You might be able to get the MAC address from your router logs or it could be printed on a sticker on your network card. You can always make up a MAC address using an online MAC address generator (just google it). Serial numbers are often on the motherboard or the case depending on the brand. I suppose you could just create a new serial number and system UUID although it could cause some licensing issue with existing software on the computer.
what would happen if you leave the uuid and serial number blank? If we must enter those values then can we enter random values or spoof them or find them somehow perhaps?
think thats the only motherboard I've seen in at least 10 years with the bios on a removable chip. lucky!
That’s what I figured too, but the Digital Storm computer was bought in January of 2017. Also the 5 year old computer I’m typing on now has an ASUS board with a socketed BIOS.
Btw, in my previous BIOS recovery video I demonstrate how to access the firmware via a motherboard SPI header and also how to desolder a flash chip on a Dell board.
I would say the developers knew they will mess up 😂
Can I use this technique for a Microsoft surface pro 6? My friends wife locked his uefi settings with a password she doesn't remember... The computer was given to me with the instructions "fix it and you can keep it, or I want a video of it exploding." I'd like to try and fix it but don't want to risk the $200-300 screen just to find out I can't do it
Hi, I am stuck as i cannot read the original BIOS, a fatal error appears stating "Error parsing BIOS data,$BOOTEFI$ signature not found. Please open correct ASUS BIOS file" has anyone else encountered this? To populate the 3 fields required I located the MAC address in the router logs, I have my motherboard serial number from the original boxing but there aren't enough characters, what should it be padded with? And I have no idea where to locate UUID. Any help greatly appreciated.
I also have a mini W25Q128FVPQ but I am having trouble with reading it with a EZP2019+ is it the reader or any problem with my placement or configuration?
Good day, can you helpme ? My problem is the following: I bought a Chinese laptop with GN117_MB_V31-T board. (Aptio Setup Utility 2021) (There is no info for that board). And I want to change the logo of the bios. I have used Aptio_V Afuwin to do the bios Backup, then I change the logo with AMI ChangeLogo Tool v5.0.0.2 and everything seems perfect. But when you restart the new logo appears ok. But it automatically enters the bios, appearing a new option RECOVERY, ROM LAYOUT MISMATCH DETECTED - PARTIAL UPDATE IS NOT ALLOWED. If I give ESC it enters windows without problem but always enters the BIOS first, any idea how I solve that problem. Thank you very much for your help.
I have a question sir.
I upgrade the bios through asus utiliy flash, then after that when i try to go ez mode and press the f2 set up it stock at black screen how do i fix it? Tnx for the response.
awesome! PC now booted but face another error stuck in "bios is updating led firmware" T_T damn asus
Need firmware for hard disk ST350413AS JC66 firmware as bios ic is corrupted
nice purple plant pot buddy
did you try to reprogram asus x541n laptop
No. I recommend you ask around on the bios-mods or win-raid forums (links in video description).
I was modding my laptop, and listening to this and i didn't understand a thing 🙃🤣
Tools ,please.
I replaced a chl8228 blown chip on a graphics card. Later I was told it had to be programmed! Looks like i2c but can't find the pins to use. Got any idea how to read and program the chip? I have another board to get the file from. Thanks for the video and any help you can mention. Thanks
No experience with that chip but cursory Google search shows you need to use CHiL Intuitive
Power Designer (IPD) GUI. I would contact the manufacturer's tech support.
@@rdagger Thanks for taking the time to answer. I have to say that is waaaaaay over my head. Most of what I have learned has been on youtube. I am working on bad video cards and after installing this chip I found that I have to learn how to read another board I purchased and then how to write to it! I don't know how to write code, just want to read and write off another chip for repairs. I have many cheap programmers, but cant even find the one to use to get started. Thanks again and stay well. I will keep looking.
do you have this method for amd am3 uefi ?
How to extract all bios exe to bin any software.
this also works with the pickit 3 programmer? thanks for the explanation
I have not used the pickit 3, but it probably would work.
hi,thanks for the informative video. I have tried doing this with my ASROCK X79 extreme 4 motherboard, however it doesn't seem to work. do you know if i can use this method on my ASROCK motherboard too? I have downloaded the bios files from the ASROCK manufacturer site and have tried using the CH431A programmer to program the bios chip however still isn't working for me. Do you have any suggestions on how to program the correct bios file to bios chip?
Thanks for your help
Sorry I don’t have firsthand experience with ASRock boards. I recommend you search www.win-raid.com and www.bios-mods.com for your specific motherboard. You’ll probably find a few people with the necessary skills.
@@rdagger Awesome, thank you very much for your prompt response, appreciate it. I have tried searching through both forums and haven't been able to locate anything on the topic. Would you have a specific link for me by any chance?
@@celinalam7765 In the following post: www.win-raid.com/t5317f16-Request-Asrock-X-Extreme-Bios-with-NVMe-Support.html the user StormRaider posts his ASRock X79 Extreme 4 bios file. Then the user Lost-N-BIOS modified it to add NVMe support and provides a download link. The user Fernando also provides a link to a modding guide he created. Any of the above users should be able to help.
Is there a tool like FD44Editor, but for ASRock motherboards?
I don’t know if there is a specific utility for the Asrock. You could ask Longsoft (the creator of UEFITool and FD44 Editor). If not, you can always use a hex editor to make the necessary changes. Win-Raid forum is a great resource. Here’s a post that might be relevant: www.win-raid.com/t5577f16-Asrock-Z-e-ITX-bios-lost-UUID-and-Serial-number-on-corrupt-bios-chip.html
Whats the procedure when you are trying to do that using raspberry? Same as in other video?
Yes, it's the same.
@@rdagger so i dont need any extra programms and commends if im doing it on RP? Im learning that topic so i wanna be shure.
@@rampifreestyler4935 Generally speaking, the Raspberry Pi along with FlashRom can be used as a substitute programmer instead of the TL866 USB programmer. For example, you can perform read, write and verify firmware operations. If you have an UEFI Asus motherboard then you can probably use all the software demonstrated in the video to prepare the firmware. If you have a different brand UEFI motherboard then you will probably need additional software. For questions regarding other brands please see the 2 forum links in the video description.
@@rdagger thanks for quick answer
asus repair H110M-R thank you
So in theory I can open old cap file,change fee version to the latest and update it,so the bios will be downgraded because old bios is working better then the latest one
I had a problem with my asus h110M-c motherboard after uefi bios update system reboots no signal to monitor keyboard and mouse could this be a fix?
If the BIOS chip is socketed then it could just be dirty contacts. You can try removing the BIOS chip. Inspect the pins and the socket to make sure they are clean and there is no contamination. Then carefully replace the BIOS chip in the socket. Please make sure the computer is unplugged and take precautions against static discharge.
@@rdagger I did like you mentioned and now it works like a charm this saved me $70 buying a new motherboard. Thanks much...
Hi dude, i can enter in bios and i can flash from bios but the PC still reboot at POST like your PC, is impossible boot everything like usb stick or SSD, simply the pc reboot everytime in POST
Do you think this tutorial can fix the problem? i have your same winbond chip
Sorry, since you can flash from the bios there isn't much chance that flashing externally would make any difference.
@@rdagger yes dude, i’ve flashed and nothing work. But depends also what program i use for flash.
Btw the pc still do this problem of post and is for mobo or cpu.
Maybe can i install some custom bios?
@@marcotermine8 Here are 2 great resources for bios help: www.win-raid.com/forum.php and www.bios-mods.com/forum
newer motherboards have the bios chip soldered on tho
I have another video where I desolder a bios chip: ruclips.net/video/KNy-_ZzMnG0/видео.html
You can also use IC test clips or possibly a SPI port.
@@rdagger cool, maybe when it happens to me
Hi, thank for the great video. Could someone recommend me similar tool to FD44 Editor but just for MSI Motherboards? Thank you
could someone (that knows what they are doing) re-write (UEFI) bios to enable M.2 slot (or PCIe 4x NVMe adapter) to enable bootable NVMe drive?? (Lenovo ThinkStation C30 - type 1136... FWIW)... "128Mbit SPI Flash with FWH"???
can i Convert .BIO File Into bin File
9MB To 4MB BIn File ?
Assuming you are referring to an Intel .bio file see this link: www.win-raid.com/t105f16-PROBLEM-How-to-open-modify-flash-an-Intel-mainboard-BIOS-9.html
it's so much easier when you can just pull bios chip out.
on most new motherboards damn bios is soldered down.
Nice one
Bad ass.
Just a nitpick, UEFI is a replacement for BIOS, not a type of BIOS
i hope it works
I bet its harder to do this on Laptops.
It’s usually harder to disassemble a laptop but several viewers have commented regarding success with laptops.
Very interesting. I am pretty sure I had a virus in my Macbook pro bios. Apple wanted me to have a new Mobo... Megabucks. Have you ever worked on Apple bios or seen such a virus in the wild?
I’ve seen many IOS devices with viruses, but I’ve never seen any computer infected with a BIOS virus in the wild. I’ve never worked on a Mac BIOS, but the repair is probably similar. If you can get a copy of the BIOS, I suspect you would need to modify at least the MAC address and serial number depending on the age of the computer.
@@rdagger Thanks for the reply that problem was 18 months ago. After getting further up the food chain with apple I could pursaude them it was better to do the repair free of charge. But I don't think I'll be really looking to get another Apple unless I was given one from work or something.
Only ASUS Wrong video TITEL then
Good job 👏 can I get your email please
LoL... Take the UEFI module off a Dell or HP motherboard and then reinstall successfully. After you do that, I'll be impressed. ASUS boards don't count and are hardly a feat of accomplishment.
87:88 :)
Incorrect.
Das war perfekt. Ich bin sehr dankbar und glücklich dass es Menschen wie du gibt die sich die Arbeit machen und sehr professionell und detailliert Hilfe anbieten und kostenlos zu Verfügung stellen. +++++++++ 🙂
ty
Nice, thank you for your explanation. I think now i can fix my asus vivobook s to boot up again.
Did you try with raspberry pi, these chips have the same pins, only their size is bigger?
Edit; I tried the Pi tutorial on a UEFI BIOS, worked like a charm, only issue is your wiring is wrong, it needs VDD on two not mentioned pins, type 8 DIP.
Thanks a lot! Facing the problem with bios in the PIPO X9S tablet running on windows 10 and hope this will help me.
id love an editor like that fd44 but for asrock....... but there isnt one i can find..... instead i have to play detective using an old one and the downloaded new bios to determine where and what to change....
POOR MEEEEE lol
...in future ill buy only asus i think....with a flashback button as well
Is there a way without external hardware? I need to roll back faulty bios but asus doesn't allow it
Thanks alot for your video,, i m interested editing bios laptop or DESKTOP,, more videos again
Great Video Thank you
i payed 40 usd to get it fixed by a technician, after this video i feel like giving him 20 usd on top hehehehe
can you help with my BIOS FIX ? Thanks Panasonic Toughbook CF-31 MK3 and MK4 Two Laptops
Hi, advice on Lenovo BIOS Editor?
Need firmware for hard disk ST350413AS JC66 firmware as ic is corrupted
I think this doesn't work for AMD
Way, way Cool! Excellent presentation.
Hello where video link how to fix gbe version on bios file
Can fit the bios file 33mb to 32mb bios chip
That was very educational
Please speak faster...boring.....
Ohh, this seems to be a pretty handy vid. Unfortunately I already ripped the solderpads out from my bricked board. SOmetimes proper gear is just better ^^
it can still be repaired with tiny wires, it's junky but should work
BANG!
hahaa
This video has been very informative, so I thank you for this!
I was wondering, do you think it's possible to modify the BIOS to add back CSM? :)
I think it's possible but challenging. I'd post your question to the Bios Mods forum: www.bios-mods.com/forum/
Well made video. Are you still flashing BIOS these days?
I recently flashed a bricked NVR. Although I had initially planned to create a video, I later discovered that there was a more user-friendly bootloader option available. Thanks for your comment!
Awesome stuff. Keep coming up with more videos.
Hi!! I have a Sager NP9870 (Clevo P80DM-G). When I bought it, years ago, it came with just one GTX 980M. So now I bought another GTX 980M in order to make them SLI. I asked for them to send it with 1617 ID but they sent me with 13D7 ID. So I couldn’t flash it right with the vbios from the older one using Nvflash. I forced with the Nvflash mismatch version and the bios chip got really messed up. So I bought spares from the same chip (MX25L2006EZNI - 12G) and spare one from the older plate (25Q20BT) and ended up dessoldering the chip from the new one and putting a 25Q20BT in the place (with the vbios from the older one flashed inside using CH341A SPI flasher). When the new 980M arrived, the notebook didn’t even started if I put it in the master slot. Now with this modification, it goes to the windows all right but I don’t get image (not even through HDMI). So the idea here is to have both cards with the same vbios and ID in order to make them SLI. The notebook bios recognize both cards but the windows just the older one (with the 1617 ID). What can I do to make this work as SLI? I have my notebook with windows 10, both cards (the 1617 one is already inside of course), SLI cable, both heatsinks and even that cooper plate that was hard to find (I have the two necessary units). I have the CH341A SPI flasher and adapters to use the right voltage. And I have a couple units from both chips (MX25L2006EZNI - 12G and 25Q20BT. The 25Q20BT is so much easier to solder and it is the same model that the older plate uses. And I tried a lot of the drivers version from Nvidia and nothing, even cleaning with DDU. Would you help me to make it work? Appreciate it and thanks in advance. I really hope you can guide me to get there and I don’t think I’m that far away!!
So I tried flashing my MSI Gaming 7 z97 Motherboard from version 1.8 to 1.9, accidentally pushed on the power cable for the GPU and now it won't display anything, won't post, will not go past F2 debug code. Any way to fix it? I'm thinking that the bios chip or a memory module went bad or that I bricked the motherboard. I powered the system off, switched to bios B and it went through the same thing. I updated Trainz 2019 from regular to Service Pack 2, rebooted the system and it turned on and turned off well before I tried to update Bios A. The Gaming 7 msi motherboard uses UEFI or UEFI/legacy
awesome video! keep it up. finally some clue on the web! I have recently replaced my Asus laptop's motherboard (G752) but I need to enter my original mainboard's serial number so that I can have my original version of windows back to my machine. does this procedure work the same for updating mainboard's serial number then updating my bios using Asus WinFlash tool? thanks
Hi guy, I have got the new version 2023+. Despite of that that in the CD is added also manual I better understand your guide.. Driver intall OK. But, when I started new version the menu comments are showing mess of letters. Firstly I thougt that I incorrectly copied the folder, but even when I started program directly from the CD it was the same. Can you advice?
Dear Sir, is it possible the following?
i have an asus b85 vanguard with i7 4770k + gtx 970 + 8gb but recently i had to swich the battery on the board because i was getting kind same problem with wierd reboots and after cpu fan error... but recently i put the bios on performance i the cores temp were crazy (82ºcelcius) most of the time....wierd sutter in games.... etc... ( my cooler only has 1600rpm )
because my motherboard is old last drives were from 2015... can i use other bios?? is it stable?
Yeah I messed up my bios and erased the chip and try writing it with the bios software off asus. Problem is after its written the pc doesn't display anything on boot. Im guessing I gotta use this uefi think to extract intels image thing from my bios .306 file from asus. You did it on a 'capsule' hopefully this works out idk wtf I'm doing
Is there any way that you can share or point me to an original UEFI bios version file for a ThinkPad T550?
I will appreciate your help.
Thanks
Can u help me I flashed a bad vbios onto my Omen HP 15 its a dedicated gpu so no optimus..I need to reprogram the vbios..is there a way I can do this.
If this problem of repeatedly rebooting occurred on a computer that was already a few years old, most people would replace the computer with a newer model. Most people would not think that they need to reprogram the firmware.
would change metal screw driver to plastic bewareing of esd. is this the best programmer on the market now? thanx for video and answer
Hello, I really loved your video! It was really done very proffessional plus easy to understand.
Would it be possible to create another one where the software release is not .CAP anymore?
