I have a t-mobile (snapdragon processor) s7 that this morning when it was charging, it must have reset or something and the logo is all i can see now. I believe it's stuck in a boot loop. When i try to go to recovery mode, it gets stuck in a recovery boot loop as well. The only thing i've really been able to do is put it in download mode, and i've tried several times to flash it, to no avail. I have a crack on the back of the device, so they consider the warranty voided even though it's been like that for a year almost. Is there anything else i should try before i pay off the phone "lease" and upgrade again? Any tricks i don't know about?

Here goes: I was a happy OPO user using the latest crDroid ROM and AK kernel, when suddenly my phone entered the sleep of death. I turned it off and back on, and since then it is in an eternal boot loop, never going beyond the Oneplus logo.
I am able to get into fastboot mode as well as recovery mode (I am using Philz Recovery), however, here is where it gets weird. I was hoping to just flash another ROM from the recovery and fix the problem, but all my files and folders on the SD card are gone, almost as if the chip died.
I also tried flashing a different ROM using ADB, to no avail. ADB shows "OK" but nothing sticks. All I can successfully flash are the boot logo and the recovery. The phone never gets beyond the logo before it reboots.
Does anyone have an idea what else I could try? I feel like sending it back for a replacement, but I am afraid that this will take forever.
Do you have a OTG USB stick ? Maybe you can flash from there.
I was able to get my phone to boot using this:

All data is gone though. But at least I don't have a brick any more.
This is me story, flashed a OTA to my cel and all the sudden my phone reboots loads up to the Oneplus logo and then nothing... Boot loop, so trying not to worry that much, noticed I could still boot to fastboot, I tried flashing CM11 praying that would get my phone back... Boot loop, Flashed CM12 and I got a low battery message boot loop, then going back to fastboot just got me a qualcomm brick, used the Color Os fix... Yay no more qualcomm brick but phone stuck on red icon, does someone have a clue what happened to my phone or if I would ever get it back to normal? :crying:
How long did you let the phone sit for (wait) and you assume it's stuck? As I know if you use the Qualcomm downloader will flash back to ColorOS and it will wipe everything automatically and your phone should be able to boot normally.(Last time when I revive my OPO if I remember correctly it will show the red 1+ logo for at least 30-45 sec.
It just sits there waited for a couple minutes, all the flashing goes ok, even with CM12S the flasing seems to be good, but it just boot loops, and the other thing when I flash a recovery it does flash it, but I cant make it boot to recovery what so ever... I just hope and pray there is a way to recover my phone since it would be a shame if someone told me, you have to buy a new motherboard... hopefully someone would just say replace the battery XD, because when I flash CM12s it does say the battery is too low to power and it keeps power cycling
Hey guys,
Sorry if the answer to this found somewhere else, tried searching but foud nothing for my situation.
My buddy, who is a super basic user and was not attempting to do anything with his phone, has a G4 that suddenly stopped working and went into a boot loop.
We tried factory resetting it and it got about half way through the apps before stopping, going back into a boot loop and was unable to get back to the same point in the factory reset.
I tried flashing the ROM using LGUP to H811-20o and it said that it went successfully on LGUP as well as the phone itself, but after it rebooted it went back into a boot loop.
Now the boot loop goes faster but is still looping and we cannot get back into download mode to try again or potentially try a different ROM. It goes to the first screen of download mode with the 5 blue dots but doesn't get past that, I've removed the battery waited for a while in between attempts and still nothing.
We can get to the factory reset screen and click yes, it will then go to the green android guy with his cog wheels exposed but then immediately goes back into a boot loop.
Any help is appreciated, even if its just a confirmation of being SOL.

So I have a Google Pixel Verizon locked model, that has never been modified, and just recently started boot looping.
It shows the GOOGLE logo on the white background for a few seconds before the screen goes black and tries to boot again.
I am able to get to the recovery mode sometimes (usually when the phone is cold and then can boot into it, otherwise just goes into the same above boot loop.
I have been able to chill the phone by putting it in the fridge, then able to get into the recovery mode.
I have attempted a factory wipe and boot, but when I attempt boot, it just goes back to the boot loop of google screen and black screen
am I bricked? I wanted to try flashing a new rom, but since its locked, and I have no way to get into the phone to activate developer mode, I don't think I can do anything
It sounds like a hardware problem, especially when you mention that chilling the phone helps. Unless someone else has some ideas, your only other option might be to go through Google support.
When in recovery, have u tried booting to bootloader and flash stock firmware with fastboot?

yes, i get an error 21, which i believe is due to the locked bootloader
Since u can't go into fastboot, I think it's best to go to a service center or something.
Good luck.

My father-in-law's S6 was rebooting right after the menu screen came up. After trying numerous things which wouldn't work (still had varying boot loops) like getting into the recovery mode and doing a factory wipe, I decided to use Odin and flash the base stock Android nougat on this (it had the one verizon security patch after that, so should be no issue doing this).
That went okay and it rebooted and got all the way to "Android is starting" which you see after a firmware upgrade. But I didn't realize the battery had run down through all this so it died at this stage. So it was taking a charge now, so let it charge overnight and give it another run.
Got up today, tried to start it...back to the boot loop. So I figured I'd flash stock again with Odin (can always get back to that mode).
It completes successfully and then after the reboot at about 32% jumps to "erasing" and then the boot loop again.
Got into recovery mode once and wiped cache (pointless at this point, but whatever) and did factory reset there, then boot to bootloader. Got all the way to the verizon screen...and then boot loop again.
Is this phone just done? The only thing I can consistently get to is Odin mode. I tried the stock reflash a couple more times and keep ending up in a boot loop and it doesn't even get past the "custom" screen now. And I can't even actually get it to shutdown for that matter. I can get to the battery pull mode but if I try to power off from there, I just get the black screen with the blue light.
And, to make matters even worse, now on restart, it brings up the blue system update screen for a second, then jumps over to the no command screen, sits there for a second, then reboots again. I think I've somehow managed to even blow the recovery menu but this has all been stock and never had any custom firmware or root.
Any help/suggestions would be greatly appreciated!
