Phone Not Booting Properly - One (M8) Q&A, Help & Troubleshooting

I have a rooted One M8 here with a custom ROM and recovery that I have been trying to boot into recovery however every time I try the phone seems to crash, turn of and then won't boot. After about 15, 20 minutes the phone boots up again by itself. Anyone else ran into this problem before or any advice on a solution? Thanks.

You can get to bootloader okay?
If so, go into fastbootmode (connected to computer) and fastboot erase cache, and try installing TWRP again.

That didn't work.. Tried booting into recovery and wiping the data and re-flashing the ROM but no luck.

So what exactly worked, and what didn't? The way you've typed it, I can't tell:
You can boot into bootloader?
You were able to flash recovery?
You are able to get into recovery?
The ROM flashed successfully?
But then it failed to boot?
Also, what ROM?
What version TWRP (version number)?
Try another ROM. Be sure to do the default TWRP wipe (data, cache, Dalvik) before flashing ROM.

I can boot into the bootloader and into the system it's self but it takes maybe 15 to 20 minutes everytime the phone is turned of to start back up again and begin booting.
I'm not sure what version TWRP is as it been months since I flashed it and I can't check because I'm waiting on the phone to boot again.

So do I have this right: The phone turns itself off, will stay off 15-20 min; during which time you can't do anything until it starts to reboot itself?
What happens if you hold power button, or power + vol up for a minute or more? Do either of these force it to start booting, or no response until it boot on its own (15-20 min).

Yep that's right.
No response until it boots on it's own.

plug it in to charge for a few hours, then use adb to reboot into bootlaoder or recovery. Flash away from there.
Code:
adb reboot recovery

Hi sorry I can't remember when adb kicks in, maybe the fastboot commands become available earlier.

Hold the power button + vol. up for about 20 seconds, or until your phone reboots.
As soon as the screen goes blank, slide your finger down to vol. down and hold that in.
You are now in fastboot.
You can also hold power vol. down during the reboot.
The first way is like a battery pull and helps clear some stuff up sometimes. It's the equivalent of a battery pull.

[Q] Phone Bricked - Might not be hard bricked

Hey all, today I unlocked my bootloader and s-off'd. I decided to install 5.0 GPE and convert to GPE. Afterwards, I was stuck in bootloader. I flashed TWRP to recovery and tried multiple roms to no avail. Then, TWRP started flickering and crashing. In a moment of stress and anger, I thought, hey, maybe it will work in the boot partition. I was wrong, and now I'm in a boot loop. I can't get to bootloader no matter what, and it just keeps showing the google screen, then the TWRP screen flickering, then reboot. Any ideas?

If it's in a bootloop press and hold vol down button which will take you into bootloader.
OR
hold power+vol up upto 10 seconds , as soon phone restarts press and hold vol down which will take you into bootloader.

Nexus doesn't boot

I'm using pure nexus rom for a while now and didn't give any kind of problem. Was casually using whatsapp on phone and battery was around 50%, phone suddenly started to vibrate. It vibrated for around 10 secs and it finally got shutdown. Now, It doesn't power on. I can enter into bootloader by holding vol down + power button for several seconds (than what it usually takes), but after entering bootloader, it doesn't go into recovery or start the phone. restart bootloader function is restarting bootloader normally but boot into recovery and power on doesn't work. Google logo appears for few seconds and again powers down. Please help! Thanks in advance!!
@cbhhargava, try to connect via fastboot

Fastboot and flash it? It's encrypted. I don't wanna loose my data. But will consider if nothing else works.
i have same shi* trying to flash recovery via fastboot and see if it loads....
@cbhhargava: if fastboot connects, you can erase both of the caches and fladh PureNexus.zip. Without erasing /data. Fastboot-syntax.
didn't work... tryinf to flash stock image via fastboot...
didn't helped either... used Nexus Root Toolkit to flash stock image - still no change. blackscreen after Google boot screen, i'm starting to think it's hard bricked either soft bricked....
then there's the oven-procedure (it's described here often): if it boots after heating, you can save your data and let replace mainboard.
Same issue

No change Shuts down after google logo... Checked the oven method but not sure how much it helps.
Found this post. Seems like it's a dead end to me. Phone is out of warranty and what ever ROM I flash by fastboot doesn't boot

Stuck :( TWRP flashing screen

So I was trying to install TWRP on my phone. I have a Mac and was looking at some online guide. I had a pin set-up, and this is what I did:
1. Installed ADB and fast boot
2. Unlocked the boot loader on the phone
3. Check the terminal commands that the device is connected correctly
4. Had the ABD and TWRP img files on the phone.
5. Tried to fast boot TWRP.
What is happening now is that I'm stuck on a boot loop of a TWRP screen, the screen if flashing and won't load. I'm guessing to let the battery die out over night
I was looking at a few threads and some say that I should flash the factory image. Everyone is saying flash the stock file... However, I can't even get the phone to turn off or go back into bootload mode for my computer to recognize the phone.
Any tips?
Hold volume down and the power button down. Keep it held down might take sometime but you should get to the loader. boot twrpRC1 flash rc2 after getting in twrp. You could also start fresh by fishing factory once you get back to bootloader
Long press power button to shut it off
or press power button and vol down together and will take you to fatsboot mode and from there you can use volume button to seltect bootloader or recovery
I don't do pin's so I'm not familiar with the hangups involved with those and TWRP.
But I guess the first thing I'd do is remove the pin lock.
Then power down phone.
Wait 30 seconds!!!!!
Press power + volume down until phone powers on, then let go.
Should boot right into bootloader.
Fastboot boot twrp.
Install TWRP from the fastbooted TWRP.
I'm not familiar with the Mac process but on a PC we need to fastboot into TWRP from an image file on our computer first, and then flash the file on the phone.
I recommend keeping a copy of the boot signer on your device, flashing this fixes most of these types of issues I have found, especially with new rom upgrades etc.
Did you let the phone fully boot into the system after unlocking the bootloader, or did you immediately try and boot twrp?
I've had this problem twice before, both after a fastboot unlock, and I had to let it fully boot into the system before proceeding

Thank you you too. That was the problem, my patience. I didn't hold it down long enough for it to boot back into boot loader mode.

Hey I think that was it. I immediately tried to boot twrp without letting the system fully boot.
Thanks you all for the support. Go XDA!
The first question everyone should be asking is if OP was on the O Beta previously.. If that is the case Op needs to flash the factory image in both slots.
Put phone into the bootloader
Flash all bat
Put phone into the bootloader
fastboot --set-active=other
fastboot reboot bootloader
flash all bat
fastboot boot twrp
Even if OP wasnt on the O beta, this should fix the issue.
After successfully flashing Oreo, I am seeing the same flashing/looping TWRP (twrp-3.0.2-0-RC1).
Long press of Pwr restarted the phone.
Rinsed & repeat a few times.
Any thoughts to flash TWRP (temporarily)?
