Hello!
Coming from a Zenfone 2, after I unlocked the bootloader, I could easily flash back the stock boot logo using adb.
Now I see that this device, once unlocked, boots up with an annoying warning message.
Is there any way to remove it, flashing back the original logo?
Thanks in advance.
This might be useful.

I have a 32gig flo, I was running 4.4.4 with TWRP and ElementalX kernel. I tried to flash 5.02 with NRT and it all went wrong. First, while flashing it got stuck at the bootloader screen - pics / screenshots here. Then I realized the bootloader was locked, so I tried to unlock the bootloader with NRT and it got stuck in a boot loop. I pulled battery and tried the “Flash Stock + Unroot” feature to go back to stock 4.4 and the command prompt came up and said it was successful, but it's stuck in another bootloop, and now I can't even get back to the bootloader menu. I didn't use force flash mode and it said to try that but i can't get to that point. am I screwed? :crying:
edit: got into bootloader menu, used force flash mode and it's stuck in a boot loop again.
I just realized there were some text documents in Simple Notepad that i would have liked to keep. Is there any way I can recover them?
Hi,
I had unlocked my boot loader to flash TRWP. But after unsuccessful attempt of H2OS installation I tried relocking my boot loader. Now device is not starting and its just showing blank screen. White Notification LED is there but nothing on screen. Need urgent help.
You...locked it with H2OS and...what recovery? What did you even do

I had official TWRP installed. I booted device into Fastboot mode and run "oem bootloader lock" command
Why? there is no real disadvantage to having unlocked bootloader and relocking often results in problems,. I have read of people recovering from this after contacting opo CS so that would be my advice

Hi, this is my first post but I had a similar problem after flashing H2OS and relocking bootloader. I solved it by holding down the power button until the white LED went out and then I booted into fastboot (power + Vol up) . from there I unlocked the bootloader and since then the phone seems to be working fine.
I hope that helps, at least in the short term
I am using OnePlus 3 with TWRP recovery and H2OS.

Tried so many things and read a lot of threads..
Battery just died and when I tried to start it up, just goes in boot loop.
Only place I can get into is the bootloader (white screen). Unlocked and S-on.
Have TWRP and rooted rom..
Won't go into download mode or recovery..
Anyone any ideas?
Possible to kinda make it 'stock' anyway to give it back into warranty?
Thank you..
5x got hot and turned off. Won't turn back on. Am I screwed?
Well, hope you have your bootloader unlocked or some sort of warranty, otherwise you're gonna have a tough time flashing custom boot images.

Bootloader is unlocked and I have twrp, no warranty. I flashed but it freezes mid-boot or doesn't power on at all.

Which images have you tried? The only ones that worked for me was the Oreo 8.1 update, after that the phone ran smoothly.
I'm going through the same problem, here are few symptoms : 1. Phone doesn't boot. It gets stuck between boot to doesn't boot at all.
2. I can access boot loader but cannot flash recovery. The phone dow not boot into recovery.
What should be done? Any help is appreciated. Thanks!
Search for 5x bootloop fix here and elsewhere. Was heavily covered when it was really bad starting around June. Too many things to try to repost, like putting it in the freezer for a while to get it to temporarily boot.
Try this fix which disables the big cores if you can.

Phone won't start but it keeps booting to TWRP for some reason.
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?

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.
