Oneplus 5t Stuck on logo and bootloader is locked (HELP PLEASE) - OnePlus 5T Questions & Answers

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 still have this problem. Stuck at logo and I can't get to recovery mode. Can you help me please?

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.

Stuck on Google Screen after JB Update

Hi,
I've attempted the JB update
http://forum.xda-developers.com/showthread.php?t=1737899..
fastboot flash boot boot.img etc.. which said all was well..
But now find that my phone will not boot up, doesn't get past the Google and unlock screen.
I've tried all combinations of volume buttons, I can get to the fasboot menu where I can choose either Recovery Mode, Power Off, Start or Restart bootloader.
None of these appear to do anything, recovery goes to the google a screen followed by an Android on it's back with an exclamation mark over it.. then goes to the Google and unlocked icon screen and stays there...
I fear my phone is bricked... Please help..

1.) Your phone is far from bricked at all. You have access to the boot loader (i.e. the screen with the options). The recovery you're seeing is stock recovery. All you need to do is go into boot loader and fastboot flash recovername (CWM) and you will have your custom recovery back to wipe data and reinstall a rom or restore a nandroid backup
Mine is doing the same thing, weird thing is, it was working since yesterday on jellybean, it just randomly froze this morning and and now won't boot..
im currently at work so i don't have admin rights to do a fastboot flash..
any idea why it would randomly stop working when i havn't flashed anything on it besides the jb rom?
Sorted..
Thanks for the comments.. yeah i was over-reacting a bit there..
I downloaded the Galaxy Nexus Toolkit, got a stock rom form gopogle, flashed it.. back to normal, well, it will be after i restore the CWM backup i took.. phew..
Thanks again
Ian.
Still stuck
I'm also stuck in the same situation(google with the unlock screen). I fear I'm a little more stuck. I also can see the recovery/restartbootloader screen. However, everything I try still comes back to that same google screen and gets hung up. Need some help!
this has happened twice today and i think it from using volume+

Boot into recovery, wipe cache, Reboot

[Q] Stuck in bootloader HTC one x

I made a series of follies trying to root my phone. Using Hasoon 2000's all in one HTC one X kit I tried to install CWM recovery before I rooted the phone. When I tried to go into recovery mode after that it would just give me that red script with the legal warning underneath the HTC boot screen and stay there. In my attempt to fix the problem I tried to flash the stock kernal which resulted in me getting stuck in a boot loop to the HTC screen with the red warning. Factory reset did not do anything. So I had the brilliant idea of re-locking the boot loader.
So now my phone boots up to the bootloader screen, no matter what I do. Factory reset, boot into recovery mode, reboot, all lead me back to the same place.
Fastboot does seem to be working which leaves some hope I can un-brick this thing. I tried several times throughout the process to clear the fastboot cache through the ADB shell which seems to have executed successfully, but made to no difference.
Can someone walk me through the steps to get back to a working phone with a working recovery mode? Help would be much appreciated!
Search XDA for "red triangle", there are quite a few posts about how to fix that.
Please use search.
There is a tread in which it is describe how to fix your phone " from disaster "
I think it is in One X Android ROM section.
Search for tutorial and disaster pr something like this.
Hope this will help you.

{UPDATE} : I was able to unlock my bootloader again which now results in a bootloop to that HTC screen with the red legal notice. I can get into the bootloader if I power on with volume down.

now I have to see if I can get this thing rooted finally.

Phone is stuck on teamwin screen flashing on and off.

I cannot use the hardware buttons any longer to even get into fastboot mode. I tried to insert a new TWRP theme, named it ui.zip, place it in the theme folder, then rebooted the phone and now it will not even go into recovery, fastboot mode, nor turn on. Anybody have any suggestions on how to get through to the recovery. I guess I locked up the recovery, and can no longer boot my phone to even be able to delete that ui.zip file from the theme folder under TWRP.
OK, now I managed to get it into fastboot mode. But that is it.
Can I extract a file from the phone in fastboot mode?
Thanks,
chevy383surfing
Well, I finally figured it out. I'll add an explanation on this whole deal after I get off work. Just in case anybody else runs into the same problem, maybe my little routine will help someone else.

Next time you loop, vol up and power for 10 seconds with phone Unplugged, then vol down and power to go to boot loader
If for some reason it doesn't restart put the phone close to a bright light

Hi. I am on a Kindle Fire HD 7 and just got cynogeanmod 12. I was going through settings when device got laggy. And somehow the device thought I wanted factory reset so thats what it did. My Kindle Rebooted and now I get a screen that says "teamwin" and every 2 secs. the screen flashes. None of the tips using buttons worked. It can only turn on and off. I need assistance in finding a way to get this back to stock(from there I can re-root and do the process again to get back cynogeanmod).
Thanks,

First, this is the M8 forum, not the Kindle forum. However, I actually can help you with that.
Most stock recoveries seem to have a problem with doing factory resets. Flash the stock recovery for your device, let it perform the factory reset, boot back into the OS (to make sure it worked), then reflash your custom recovery.

Tank you for this quick reply :good: . I will try to get back into my stock recovery but if it is on my device, how will I access this on my computer and force flash it on my tablet. I only need help making the tablet responsive/workable. Once this is done I should be able to figure out the rest.

I have tried exactly that. "flash stock+ unroot" with the nexus in boot loader mode. After complete, the nexus will remain in boot loader mode until I restart it manually (press power button on nexus). Wug's toolkit would not reboot it after successful flashing. Is that normal?
After manual reboot, it still stuck on google logo.

I was experiencing this problem last night. However, I used WugFresh's NRT but when it asks to flash stock and unroot, make sure you check the box that says your nexus 7 is softbricked. Also, you may want to note what version of android it was last running before it was bricked. It worked for me and I was able to update to 5.0.1.
*Edit: The only thing you need to do is make sure fastboot is enabled, and you should be good to go.
P.S. DO NOT download the stock images from google to your computer, let the NRT automatically download it for you. It saves you time, storage and stress. Once done, also install the recovery from the NRT, that should be able to do the trick. Not sure why your device won't restart, you may have to flash again.
wugs
I had to use force flash in wugs, go to options and set it there and try a previous version. Best of luck.
It's fixed!

Haha, I found the solution elsewhere in XDA. So if you haven't beaten your Nexus 7 so bad yet, TRY this: press and hold the power button for about 1 minutes. The slate turned off and on several times, and I found nothing. BUT after several minutes (while I was watching Youtube to see how to remove battery; that would be the last method before throwing 5 stories down to ground), the Nexus BOOTED BACK:good::good::good:. Good luck!:laugh:
And I'm using Glitch kernel and turn off flar2's double-tab-to-wake. It's a neat feature, but can get us into big troubles.
That still doesn't work for me. Pretty sure my eMMC is dead, so I'll need to replace the motherboard.
Anyone know if a 16GB motherboard works in a 32GB Nexus 7 2013? 16GB motherboards seem a fair bit cheaper, and less rare.

[Q] 'Secure boot Error!' at boot, download mode and factory reset don't work

Hello,
Here is what led to my issue:
I rooted my phone using this method: http://forum.xda-developers.com/showthread.php?p=38886073#post38886073
Downloaded clockwork rom manager.
Here comes the thing I don't remember. At least i know that the last thing i did was to click on 'backup current rom'
After this the phone reset itself and this message came up:
Secure booting error!
Cause: boot certification verify
Then i tried to reset using the power button, which led me to the 'battery full' screen - afterwards i was able to reboot. As stupid as I am I just tried the same thing again. And ever since i am stuck at the 'Secure booting error!' screen.
I am unable to enter download mode. I get to the 'Hard factory reset' screen, but if i accept doing so, it says 'Secure booting error!' again.
I also remember clicking on 'restart into recovery mode' at some point, but this is not the last thing i did.
I am really desperate. Please, help me!
Well i had the same issue today... It happened after i did two changes. One of them was to to try to relock from freegee and flash twrp again from freegee. In my case i was able to go in download mode and flash original kk rom with lg flash tool.
Unfortunatly, trying to boot in downloadmode, i still get the same error :/

How are you trying to boot into download mode? And what factory reset screen? It seems as though you did not unlock the bootloader using freegee, if you make any changes and relock the boot loader you will get that error. But it seems that it has not been unlocked. If you hold power and volume up what happens? Same thing when power and volume down, one of them is recovery (possibly factory reset you are seeing) and the other is download mode. I don't remember right now but you should read the whole softbrick thread and see if you are missing something. You may need to use LGPNST to go back to stock, you can also use that program to flash a new recovery so read carefully and follow all steps.
When this happened to me I was able to flash an unlocked bootloader and it allowed me to use my phone again as it was before doing something stupid (for me it was an attempt to re lock the bootloader).
well, i managed to get into download mode. Obviously i used the wrong method to get into download mode...
I used this method and everything worked fine, so far. : http://forum.xda-developers.com/showthread.php?t=2249500
My phone doesn't boot now. Fast Boot doesnt work aswell.
All that happens is a white battery showing on the screen and when i try to fastboot all that happens is that the LED is blinking or glowing red after some while.

What do you mean when you try to fastboot? Fastboot is basically the bootloader and allows you to select recovery or download mode. What you should have done after following that thread is go to recovery and wipe everything and flash a new ROM.
If you are saying that the bootloader is not coming up and allowing you into recovery then I believe something was missed.
After trying out some varioants of this it worked: http://forum.xda-developers.com/showthread.php?p=40274560&highlight=red+led#post40274560
I wiped the phone, but since I had to leave over the weekend i just turned it off and went away.
Now that I am back, nothing works now :/ The Phone doesnt react to anything, not even donwload-mode.
Is the battery too low maybe? It's on the wall now for a few hours, but it still doesn't react. It's not warm either.
edit:
when i charge the phone, i will get a 'watchdog bark' after some time allowing me to get into recovery. accesing downloadmode from there doesn't do anything. strangely, the recovery isnt trwp although it should be because teenybin comes with it. it's 'bbs.gaodi.net' which doesn't have a sideload feature. what do i do now?
edit2:
after 10000 tries i got into download mode. i don't want to **** up now so i won't do anything until i know exactly what to do.
any advice?
edit3:
got it working by flashing another teenybin which included trwp - then i installed miui via sideload. i don't have signal though, but i will open another thread for this since this is another issue.
