- There are many causes for Samsung won't turn on issue. As for Samsung not turning on accompanied with 50mA-80mA boot current, the first thing we usually do is to check the power supply voltage. If nothing goes wrong, the fault is most likely related to CPU. If there is abnormal voltage measured, then check the corresponding faulty position on the board. For our case today, the fault component is finally confirmed as PMIC U7003.To fix the S7 edge won't turn on issue, we can replace it with a new PMIC. Let's check the video to find out how to troubleshoot Samsung S7 edge can't turn on.

Hello sir,
I watch some of your RUclips videos and It's great. I am writing you because I badly need your advice.
Some days ago, my Samsung s7 edge handset suddenly crashed. It's not open, just showing some red lines says: Boot loader exception.
It didn’t come to download mode. But the main thing is the device internal memory was 128gb. I have important documents there and need rocover those data. There was a warning that, memory almost full. But before I delete some data, this problem happens. Attached screenshots.
But it seems like my phone's storage is corrupted, may be it is already deleted. I think, from what technology we have in our country, last option is separate IC/Emmc from motherboard. And try to revover data from it.
Do you think, this process will work?
I saw your videos about it. I think, my Android version was 5, phone was rooted so may be those data was not encrypted. So it is possible? Or if it is encrypted, is there any chance??
Is there any other way like if i restore that IC/emmc storage in another motherboard, it will work or not?? Please give me suggestion that, how can I recover those data?? My main goal is to recover data. I will be forever grateful, if you can help me.
Thanks & Regards,

I love the music.
Hi. Seek advice for my symptoms. When booting is successful, it is maintained for 3-4 minutes. And it constantly reboots. Only the initial Android logo comes out. Please let me know if I need to replace the video PMIC or another chip.
good job
superb :)

@@herfordkingsly7979 Doing something I love while helping clients is greater than any other job, no matter the salary
@@herfordkingsly7979 Lol it isn't because you hated your life / work and couldn't succeed that others won't, your opinion is irrelevant and you seem like a nobody.
@@herfordkingsly7979 Damn it sure does sucks to be you Steve, I hope you can still afford to feed your daughter with that job of yours that apparently "sucks". If you don't enjoy what you're doing there's no need to spread negativity about it on here, it's nobody's fault but your own if you suck at it, I've self-taught myself how to micro-solder through-out college and not only I love it I'm also good at it, but no Steve it seems like you're the type of idiot that purchased an Hakko thinking you'd become a master in this line of work but haven't managed to payback a penny for that hakko, No wonder you say your job sucks. I pity you ):
thanks super video

......
Im scared to doing like this..
Dont do it by yourself

Broke my digitizer doing this, now I have to buy a new phone.
Is it affect the IP68 Water resistance??. If opened for once and repaired. My phone had the same problem then I repaired it by sending to Samsung care.
It will lose the water resistance function after disassembling, but you can get the function back to some extent after special handling.
I've got 2 Samsung S6 Edge phones, both have been flashed and re-partitioned with correct software. Factory resets have been attempted after flashes.
One sometimes completes boot, however if it completes has no IMEI/no service and has artifacts on the screen when you change from app to app.
The other one either stays on the initial "Samsung Galaxy S6 Edge" screen, but sometimes progresses to the pulsing "SAMSUNG" logo screen where it stays with a blue LED, which after some time it loops.
Any help would be great thanks.
No IMEI/service: It might be related to Baseband.
Stay on Samsung Logo: Try to flash it with Odin mode to see if it can enter to the system normally.
Thought it might be a Baseband issue, but would that also cause the artifacts on the screen?
As mentioned, already tried flashing it with Odin with no success.
very gooood
If my s7 edge restarts every minute whats the problem?!If you can help me?
Did u fix it?
what cause would be 300mA boot, no display and charging with 200mA. If you say 50mA is a CPU fault (or PMIC) what could cause 300mA? No liquid damage or short found.
dead ufs
There is any way to save all the data from the phone ?
how is the air temperture? THX
The most important info,...
My S7 edge starts up but won't open...is this the same fault? It's at the shop now in repairs...can't see them doing this...I need the data so no new master board 😤
Plz do some software fixing
Same issue with a customer's s7 edge phone.
I changed PM ic but phone is same condition taking 0.040 amps and stick on that amp.
What could be issue now
hmm, my phone is taking around 0,2 amps, im so confused :D
Can i send the Samsung S7 Edge for you to repair??
It is the exact same problem as the video...It won't turn on after a reset to factory setings.

does it always restores to factory settings? what if I have important information that I want to recover?
most of these tutorials just show you what to do, nobody said they do it or it actually works
My S7 Edge won't Turn on after reset to factory setings, is completly dead. I went to Samsung store and o fix the phone they asked 500€. Do you know where can i find the PMIC Board? (Maybe on eBay?...I don't know if the problem is that?!)
If the power ic voltage is normal but phone do not power on
So what can I do sir
The fault might related to CPU.
Awesome
Mine was frozen, - could not start op again so heated it up - used a suction device and my drivers licence, - began to slide the card down to remove the back cover, - and it bursted into life ???
Any suggestions to what happend??
At least this method to open the back leaves n o traces at all !

Can anyone tell me if a s7 edge sm935f logic board work in a phone with a s7 edge sm935u
yes.
can i send you my samsung galaxy s7 edge to you to repair it wont turn on and i need the data in there
How do these problems even happen to people’s phones? What do you do to make it fail
Where do I get Pmic
store
Whats the name of this chip? I want to buy one
Is this worth doing financially speaking?
I love the S7 but Ive bought two brand new in a row that have just gone dead, one in a year, the other in 2. While they are cheap to buy and do everything I need in a phone it makes me not want to buy them anymore because their reliability is so low. I feel like phones are a suckers game nowadays, I'd rather be a $250 sucker than a $1200 one :)
well, my s7 Edge Is nearly 8 years old, and apart from a broken LCD and a battery It Is completely fine. i use It as my second phone. i can suggest you a Motorola Edge 30,wich i use as first phone.
S7 Edge turns on all the way to T mobile logo then turns off. Will not load OS. When we try to charge we get a YELLOW triangle when using wireless charger and a white charge circle with white lightning bolt static not blinking when we plug in USB charger. Tried reset, cache,wipe etc. NO LUCK. Had to return it. This happened after phone power ran out the night before. We left plugged in to charge for few hours but no luck.
Oh yeh great idea open up ur phone 👍 I
Hello sir Hamako mobile ripening sikhana hai Aapaka instuete Kaha pe hai fess kitana lagega apana whatsaap no. Do sir
I think it is better to have the real audio of you fixing the phone rather than covering it with the music.
So sorry for the poor experience. We will keep improving.
like sir
Muy mal, así como lo muestran el equipo va a tener problemas de soldadura del procesador pq esta del otro lado del pmic
Fake
