[Q] Black Screen

So I began the root on my One VX and the phone restarted. After the restart I can see the background, no unlock circle or anything else. If I turn the display back off and on the screen will light up but stay black. Any help would be appreciated.

he wont have to do all that, he can simply go to Fastboot if he Dev unlocked and flash twrp recovery wipe and flash JMZ rom, and it will clear and boot properly, System UI, is rom based

Choose reboot and choose system.
Also, update your recovery to v2.8.7.0.
Also, a hard reboot isn't going to make an update appear.
You bought the phone second hand, I presume?

Is my M8 bricked?

Hi XDA-Fellows
1) thanks for all the help of this community so far
2) my problem: I had my HTC One M8 rooted, installed TWRP (I think in the end I had 2.7.8.0 as last version) and Cyanogenmod with a nightly build of around 18. March 2016 installed! THEN the big mistake happened. In advanced developers menu of cyanogenmod I activated the option that was called something like "on update of system also replace recovery software". That obviously was stupid.
Upon rebooting normally TWRP launched and installed the latest nightly. This time I see the white screen with HTC logo on it, red text in bottom, top part of the screen shows "ENTERING RECOVERY", 3 seconds later I see a black screen and every like 2 or 3 seconds it looks like the screen gets powered, it flashes darkgrey shortly (again, looks like it gets powered but instantly shuts off immediately).
This just can be stopped by pressing either P+U or P+D for like 10 seconds. Then again, white screen with HTC logo and ENTERING RECOVERY and the screen switch on/off-loop.
Is my device bricked? What can I do now?
Any help is appreciated.

Hi,
Can you enter to your bootloader ? So maybe you can just reflash it to see if it's going to work..

Yes I can enter bootloader. How should I go on from here on?

Well you just need to download the new TWRP from their web site https://dl.twrp.me/m8/ after that you put your device into bootloader and you plug your phone into your computer and download a toolkit from xda like htc one m8 toolkit and you follow the instructions..

Thanks. I will give it a try and give feedback.

It worked. I could enter bootloader, switched to FASTBOOT mode, installed ADB Drivers for windows and replaced recovery with latest TWRP! THanks a lot for your help! I thought I could throw away my M8

Well. It worked not completely. I was able to reboot my phone into the Cyanogenmod. But upon entering recovery mode (which I expected now to be TWRP) I get the same result again ... Screen off/on within seconds, repeating endlessly

I think you need to reflash the boot.img and the ROM completely. Because i don't know why do you have a black screen.

I activated root access for apps and tried ROM Manager first! It failed, then I used flashify which worked. Automatically downloaded latest TWRP (3.0.0.1) and flashed it, reboot into recovery. Everything works like a charm again! Thanks again for your help!

Oneplus 5t Stuck on logo and bootloader is locked (HELP PLEASE)

My one plus 5t is stuck on logo after an official update and the bootloader is locked.
Is there any way to unlock bootloader without access to OS (OEM unlock), so that I can flash any custom recovery?
Or any other solution from experts?

Use fastboot to OEM unlock.
Read up on some tutorials, this one is easy to fix.

I read this but they are saying that you have to go to setting and developer option to enable oem unlock first, but i cant access to my device because my device is stuck on logo screen.

I would suggest you do this first:
https://downloads.oneplus.com/oneplus-5t/oneplus_5t_oxygenos_5.1.1/
Then you should be able to boot to android again. Then tick the OEM lock button

Just enter stock recovery mode and do a wipe factory reset. If it doessnt work, just falsh official oxygen os and do the factory reset again.

If the reset doeesn't work there is a cheat that will work if encrypted and your data is backed up... Open the stock recovery which will require a password. Select the dont remember button at the bottom. It will warn you that procedding will wipe your phone. Do it. The recovery will wipe and reboot your phone with the stock image you just tried to flash. You WILL lose data.
If you cant access the stock recovery or TWRP you can boot either on your PC and perform a wipe from there. You can then move a stock image over to root and flash it with the stock recovery.

I have this same issue, stuck on one plus logo on boot. Can enter fast boot menu but can not enter recovery mode.

Do you still have that problem?

Do a factory reset in stock recovery. If it doesn't work, then use this guide

I am having the same issue. After the android 10 update and after my first restart, it gets stuck on first android boot screen. Not ever the oneplus screen is shows and phone screen becomes dark with led on in grey color. I tried wiping the cache and did a factory reset too but it did not work. Help me what to do. Also where can I find android OS image list of 5T and a process to flash it through PC (ADB commands may be or something else?)

Someone pls help me. My Oneplus 5t stuck in logo screen & not moving to any further screens.
1. Switched Off the phone
2. Now turning it ON & logo screen has come
3. After 5 to 6 seconds logo screen disappears & white LED indication starts glowing.
Pls suggest what to do.

Have the same problem, MSM tool doesn't help.
