OnePlus 8T stuck on boot - OnePlus 8T Questions & Answers

Hello, I was using my phone normally and then I decided to turn it off because I was having a bug with an application, then I turned it on but in that process I accidentaly push one of the volume bottons and end up on what it seems a boot menu, I went for the english option and then to "exit" and "power off" so I can exit this boot menu, but it comes back again to this menu over and over I don't know why,.
I go to boot reason and appears this: fs_mgr_mount_all
Unable to parse kernel log.
I need help, don't know why I can't exit this menu because I entered by mistake and did nothing else than trying to exit. I have never root my phone or anything related to that, please help me to not lose my data!

Try booting in Recovery and clear Cache (only wipe Cache not Wipe all) and then reboot
Maybe this help you

Ok just done that but it is still stuck on boot, maybe there is another solution to this problem?

Hmm looks like your 8T is caught in bootloop. As far as i know there is only to try in Recovery the Wipe All step which deleted all on your Phone. If that also not works then MSN Tool which has the same result as the Wipe All, the only differnce is that MSN Tool sets up your Partitions fresh and complete clean.
But i can be wrong with that what i Knowing, maybe a more smarter guy can help you out with your problem.

If your phone bootloader not unlocked, the only way i know is fastboot flash .img file from official full update.zip
If that not work, wipe or MSM, but they all causing data loss.

[Q] My Nexus S cannot boot

Hello,
I was trying to root my Nexus S, and in the mean time don't know what failed, but now I cannot boot.
If I boot normally, pressing the power button, it gets stucks in the screen showing "Google" and nothing happens.
I can access the recovery menu if I press the volume up button while pressing the power button. I tried to reload images and recover from them, but it always get stucks in the image of the android with the exclamation.
My question is, does any of you know how I can repair my booting? At this point I don't care if I lose the root or not.
Thank you!
The exclamation is probably the stock recovery do you know how to use ADB

seems like you never flashed to stock or bad flash try full wipe and flash either rooted stock or custom rom
Didn't help, no useful solution in that thread, however will keep an eye there if something new comes up.

in clockwork mod

but from root and stuck on bootloop you might need to reflash the rooted stock rom. it is usually PDxx.IMG what root method did you use? did you get any errors?
I got no errors.
I already tried to flash with several differents .img, but none worked so far... I tried really a lot differents. Always get stuck at booting.

Hello!
If you see the triangle and ! when you go into recovery, then you just need to flash clockworkmod recovery. Then you can flash a ROM.
if your in clockwork do full wipe then flash new img i always do this order
-mounts and storage
-format /cache
-format /data
-format /system
-back to advanced
-wipe dalvik cache
-wipe battery stats
-*****go back****
-wipe data/factory reset
-now flash rom
already tried, didn't work... nothing happens
the same happens, still get stuck during booting....
after wipe do you see rom install

Undo Format Data?

I am a relatively new android user but do enjoy flashing roms, kernels etc
My problems began when i was trying to flash a new rom on my Nexus 5
I was trying to flash this rom http://forum.xda-developers.com/showthread.php?t=2655722 but despite doing a factory reset and wiping the dalvik cache and cache it refused to boot in to the new rom
I tried to flash the rom multiple times but without success, eventually when trying to boot into recovery to try again i was greeted with an unthemed TWRP recovery asking for a password despite the fact that i had a custom theme and multirom installed I tried to proceed anyways but was greeted with E: unable to mount storage
In desperation i tried to solve this problem and found this

TWRP asking for password
After unboxing my Nexus 5, here's what I did:
1. Booted into bootloader
2. fastboot oem unlock
3. Flashed TWRP v2.6.3.0
4. Booted to recovery
The screen that greeted me says "Please Enter Your Password".
I can hit the cancel button below this which takes me to the normal TWRP screen. I then pushed SuperSU to /sdcard, but when I flash it it fails because it's unable to mount /cache or storage.
When I reboot to the system, it takes an awfully long time (approximately 30s) to progress past the "Google" screen, and then it just seems to sit on the booting animation forever.
Any help?
EDIT: Solved my own problem.
Hit cancel at the password screen, then go into Wipe and then do a factory reset by swiping. Then go back into Wipe and press the 'Format data' button. You have to type 'Yes', and it will take a few seconds. After that everything should work normally.

I now fear that i maybe without both a rom and all my files such as my music that was stored on my phone.
Is there any way for me to undo the damage i may have done to to my phone?
You can't recover the data. But you can push files over with ADB.

[HELP] Need urgent help with avoiding a data wipe...

Basically, my wife's phone was constantly rebooting. I had heard of power button issues so I tried to open the phone to fix that. After fiddling around with the button the problem persisted. I read somewhere that wiping the cache would help so I prepared to do that.
As I was waiting for the cache to wipe... the phone reboot again. It now does not boot (sits on the boot screen after the Google logo goes away) and says invalid argument when I try to wipe the cache.
According to this post, flashing the cache.img will fix the corrupt cache and allow me to wipe it.
Unfortunately my wife's phone has not been backed up, nor has the bootloader been unlocked. Is there ANY way to backup/retrieve files before unlocking the bootloader so I can fix the cache corruption issue? She has stock recovery, running lollipop.
Would really appreciate help in this matter, the pictures on her phone are from a year of travelling (not my best idea to leave them on her phone...but I digress).
If your phone keeps rebooting, and bootloader is LOCKED, its going to be hard to do anything to recover user data.
Having said that,
If you had ADB debug enabled before this disaster, you could try to ADB Sidleoad the Nexus 5 Lollipop OTA zip from stock recovery.
Then you data would remain intact.
Best of luck

I can flash custom recovery without unlocking bootloader or wipe. If the /data partition didnt get corrupted we could recover the files.

Has my brain gone broken? I thought you could fastboot stock img files without unlocking the bootloader?

You can try that too.
What version of Android did you have on the phone?
In order to flash factory images, you’ll need to have the Android SDK HERE
Then you need to download the same version of Hammerhead Factory Image
you have been running on her phone HERE
Extract the correct Hammerhead Factory Image using 7zip or other extractor tool.
Then copy the cache.img from the extraction to the SDK/platform-tools folder.
From within your platform-tools folder, open a command prompt.
I'd recommend wiping the partition before flash.
-First type the following command
fastboot erase cache
-Then type the following command
fastboot flash cache cache.img
Plenty of tutorials in the sticky's if you need to learn more .

Nexus 5 stuck at boot animation

Guys nexus 5 was working fine.. After uninstalling few apps i decided to restart the device so so i power off the device and then turn it back on ever since device is stuck at boot animation
Plz help me out
Unfortunately your device is locked, which means you will lose everything on it (hope you use cloud backups).
You can try one thing first. From recovery (third image), try wiping the cache partition. What happens? Same mount errors? If not, try to boot.
If it still doesn't boot, you'll have to flash the factory images, which involves having your whole data wiped.

This is a known problem. If wiping your cache does not help look here

Oh well. If you want guide then sure. Here you go.
First of all let your battery drain completely. Once battery is dead. Plug your phone into charging and as soon as it shows three options boot screen quickly press Volume Up to boot into recovery. It will boot TWRP. Only if you tried via HWOTA 8. Read OP to know complete story. Now once in TWRP keep your phone on charging and don't let it shutdown. In TWRP go to Wipe and Format Data. Do it one to two times. Now go to Advanced Wipe and individually select each of the following one by one.
Cache
Dalvik Cache
Data
Internal
System.
First select repair file system and then after it repair wipe it individually. Then do a collective wipe. One or two Swipe to factory reset. After this cleansing flash firmware for Oreo of the build you were trying to go-to via Hurupdater. Search for it and follow exact guide. After that select Reboot Phone and when it's powering on, you should get three options menu. Press Volume Up to enter erecovery. This time you will boot normal recovery. Factory reset and then Format cache. Reboot system. First boot will take time. Be patient.
After you reboot you will notice several apps missing and themes not working as well as pinkish wallpaper instead of purple one. To fix flash any Oreo Compatible TWRP or the TWRP form Elemental ROM thread. Go-to wipe and format data. Then advanced wipe and select Data Internal System Cache and Dalvik. Wipe and then reflash Firmware via Hurupdater. After it finishes, reboot system and then reboot into stock recovery. Perform factory reset and then format cache. Reboot.
