g920f freezing at startup - Galaxy S6 Q&A, Help & Troubleshooting

Hello
G920f came to me that cannot startup. I powered on but after 10 seconds it freezed. if you leave longer powered of it can works maybe to one minute and freezed again. I tried 4 different flashes but same. I tried to hard reset but in freezed on android figure. I flash unikernel so I could enter on recovery meny made hard reset and wipe cache but still same situation. The phone is brand new and costumer said that he had this problem from begining after thid day of work and he didnt bought with warranty. Most likely its looks like hardware(CPU) problem but I want to know if any has these problem and if anyone has managed to resolve this problem

Might be a lemon S6. Return your S6 back to Samsung for warranty replacement.

I'm also in limbo, can't get into stock recovery at all to wipe anything it gets stuck in the android Logo, custom recovery like twrp and phil just freezes up also flash kernel with root(S6_UniKernel_v8-0002-ODIN) still no go I did just about everything I had up my sleeve and some I didn't mention still nothing still freezes.. Also flash firmwares just end up with the same result

[Q] Bricked/Boot Loop Galaxy Note 10.1!!

Hello fellow XDA members! I am a Noob.
So I believe I have a Bricked Galaxy Note 10.1. Model GT-N8013
I Rooted Stock ROM, and flashed Collective Edition 5 Dark Side.
So heres what happened, everything seemed fine, until I made a mistake, I was Pimping my ROM with the PimpMyRom app. Every change seemed fine and my note worked, but when i saw the double boot screen slide in the app, i did what it said, i have the imf support or something like that. Then after i had the ''support'' needed, i clicked install button on the double boot slide, it seemed to do something and requested nothing, so i went ahead chose a second clip, and clicked set as second boot screen. It said it wont take effect until the 3rd boot, so i rebooted 3x, but at the third time, it was stuck at the boot screen with the galaxy note 10.1 logo ! It did not start or did anything, over time it would turn off and automatically reboot, but it would get stuck again !.
To attempt to fix it, I Booted into recovery (CWM) and did everything i could. I wiped nearly all cache, factory reseted, then out of fear, i flashed the stock firmware ROM from Sammobile website, with ODIN, and to my knowledge, it got worse!! It booted, seemed to do something then in the logo screen it got stuck once again!! Stock recovery says unable to mount /efs, i don't believe EFS is completely corrupted, I left it stuck for awhile and it shut down in like an hour. Help, what can i do to fix this!?!?!?!
Device cannot boot up.
I could boot into recovery and download mode only.
I thought that I too had bricked my 8013 the past weekend. Trying to do something that I shouldn't. It took me a bit of work and a lot of worry (my wife gave me my 8013 for Xmas and if I had to tell her that it was now a doorstop, she would have killed me). I used this method to get back to stock and then was able to work my way back to the ROM I use. I disremember in which order I Odin'd things, but in the end was able to un-brick. All I can say is give it a shot.

[Q] Need help galaxy s2 i9100 boot loop and freezing

Hello I am searching for help. The problem is that my galaxy s2 i9100 stopped working properly. It started like this maybe I took out the battery or something I don't remember and then I turned it on the phone wouldn't boot. I thought maybe my android operation system got bricked so I decided to re flash it but as I can remember the phone wouldn't go in to download mode but some how I managed to reflash the firmware but then phone booted it just froze and then I pressed lock button the phone screen would go black and reboot. After installing cyanogen mode 11 the phone would boot and it could be used again until pressed the lock button it would go black and reboot so I have been reading forums and found problems like boot loop corrupted mmc or something else corrupted and I don't know what the real problem is because the symptoms are like boot loop or corrupted mmc or soft brick. I have already tried other kernels other android versions clock work mode

I have found that my emmc has the insane chip bug. The phone boots normally with cyanogen mode 11 but then it goes to sleep mode or I press the power button the screen goes black and the phone restarts. I have tried siyah kernel to try dual boot but then I flash siyah I cant get into recovery.
I think you should flash latest STOCK ROM with Odin, and then follow available custom rom instructions on xda...
Test if the stock rom will work for you, boot your phone etc... Try to use it a few days. If everything is OK, proceed with
further procedures...

I have already tried this but with the stock rom phone boots but at the section where I have to chose language I jus freezes stops working
So I think it is a hardware problem. Phone on stock rom shouldn't freeze on language selection. Something is wrong. If you are on warranty, let them fix it for you, if you are not, try to fix it in some phone repair point. I'm sure you can stop your attempts. It will not be better for now.

Stuck at boot screen even after restore with tot method...

Hello Everyone,
I have been trying to help my friend with his soft-bricked G3. He wasn't rooted and had never even played with flashing anything, it just stopped booting one day and would display the "LG Life's Good" boot screen for a few seconds before going black and then just repeating this endlessly. I was able to get into recovery and download mode so I used the tot method to flash back to stock after a hard reset just produced the same results.
When I flashed the stock firmware, everything appeared to work fine, it went through the MiniOS bootup and everything, said success, gave me the hard reset status screen so when it finished I pulled the battery as instructed and rebooted but the phone still has the same issue. I have tried to run factory reset through recovery now that I flashed the new firmware and it still does the same thing, just hangs at the boot screen for a few seconds before going black and then trying again, endlessly.
Has anyone encountered this before? Is it bricked?
Thanks.

Galaxy s6 G920v stuck in bootloop, have tried everything

Hi guys, so recently I bought a Galaxy S6 Verizon off of eBay. I got it for fairly cheap because it was stuck in a boot loop. I usually have no problem fixing stuff like this, but this time is different. So the first thing I tried when I got the phone was to do a reset and cache wipe from recovery. I rebooted the phone and it showed a screen that said "Android is starting, optimizing app 9 out of 31." when it got to 21 the phone rebooted and went back to 9. It did this several times before I attempted to wipe/reset again. I then downloaded the tar file G920VVRU4CPH1 and flashed it in Odin. I did a manual reset before the phone booted, and it is doing the same thing again. reboots to a green screen where it tries to optimize apps, stays there for about 20 seconds, and reboots over and over again in the same cycle. I have tried all other stock marshmallow roms that i can find, Odin won't flash older ones, (assuming its not letting me downgrade). Also another weird thing, every time I flash, the blue update screen goes to 32%, stops, erases, and reboots. Phone is on 6.0.1 version MMB29K.G920VVRU4CPH1 as seen in recovery. Any help would be gladly appreciated. Thank you!
I am having a similar problem with loading new rom. The farthest it gets is 32%. Sometimes it doesn't get even that far.
I ended up just buying a trashed s6 and swapping the motherboards. Only way I could fix it

Samsung S6 stuck on Samsung Logo after flashing stock rom

Hi Guys,
So the issue seems to be straightforward and I read many threads about it, but none of them actually solve my problem.
My S6 is locked to Orange Poland (which is currently running 6.0.1 Android). I wanted to flash unbranded Marshmallow rom but that did not go well and in the process of flashing Odin returned an error (Complete(Write) operation failed). That's the way my phone became bricked. I tried to reflash this rom several times (while changing ODIN versions and also I tried single AP as well as 4 files + PIT). None of this worked. So I decided to go back to the branded rom—exactly the same as it was before.
Odin this time didn't show any fail messages and the phone actually started booting up. And here is my problem, it is stuck on the Samsung logo. I tried going to recovery mode, wipe cache and then factory reset but it still cannot go through Samsung logo.
My phone was never rooted. I have up to date samsung usb drivers. I tried SmartSwitch but it fails to recover the phone every time.
Do you kind people have any ideas?
Hi again,
Just a quick update from me. I finally managed to revive my phone. It seems that the bootloop was caused by the low battery (actually 0%, while being connected to PC). Once I charged the phone to 100%, it miraculously booted up and went to the setup wizard. I have no idea if the low battery had an effect on it, but once I charged it, the phone started to work properly.
In the end, I flashed back the stock rom with Orange Poland brand. The rom consisted of 4 files + PIT file. I used Odin3_v3.12.3.
Maybe this will help someone

Thats why you should always charge your phone to at least 70% before doing any flash :good:
