help to lock bootloader - OnePlus 3T Questions & Answers

My OnePlus 3T is currently rooted unlocked bootloader nd on TWRP recovery
So now I want to move my phone to stock condition pls help

Simplest way would be to just run the Qualcomm restore tool/unbrick tool. This will restore everything back to unrooted and locked bootloader as you've requested.

You could do a factory reset in TWRP and flash the latest OnePlus stock image from https://downloads.oneplus.com
Then reboot, which will restore the stock recovery and re-encrypt your phone (if you've decrypted it). Check that this is so in Settings>Security. Also check that recovery is now stock.
Then you can relock the bootloader from fastboot.

Link to downloading recovery is there along with link to download the ROM, just check the website.
If you flash stock ROM through TWRP, your phone will be automatically encrypted and stock recovery will be installed after reboot from TWRP.

So what do you suggest should I flash stock recovery or I should install full ROM from twrp nd automatically get stock recovery.

If you flash the full stock image in TWRP and nothing else, then when you reboot the stock recovery will replace TWRP. This is the way I would do it.
You can verify this by booting back into recovery after the phone has booted up on OOS. Note that if your phone was decrypted, then the first boot up will take a while to re-encrypt the phone.
I would not relock the bootloader until you've verified that the phone is encrypted and the stock recovery is installed.

Hi,
I did the following procedure
1. Unlock bootloader using HTC-dev site.
2. Take nandroid backup of stock ROM.
3. Installed Sabsa prime v15
Now I want to go back to stock ROM.
4. recovery says restore complete of Nandroid backup.
5. I flash boot.img from nandroid backup (I am on S-ON)
6. the phone boots up and directly goes to recovery instead of normal boot.
How can I get back to my stock ROM now?

Yeah, I had to do the same... I downloaded the RUU from htcdev and flashed. But I am not sure why nandroid restore didnt work. Is it because i was on S-ON?

Sabsa prime Rom has this issue, it doesn't get completely wiped off with factory reset.
In the recovery go to advanced, format /system.
After this restore from CWM. After the restore gets completed, flash the boot.img file from fastboot usb mode.
No, again go to recovery and select reboot.
I hope this will work.

Help plzz..

Whenever I try to flash anything or do anything like wipe or backup using twrp 2.8, the phone got restart automatically between the process without doing the task Complete...

Probably your device's recovery replaced by stock recovery.
Inorder to prevent this , you shouldve uncheck mount system read-only.
Anyhow, now you can still root your phone and install a custom recovery with a tool!
if you wish I'll link it here!
BTW, your device isn't booting now?
Pls its ok to me but i dont have a pc

[Q] TWRP lost after flashing 4.1.3

I've recently flashed my OP3T with stock ROM 4.1.3, & do the clean flash with TWRP. After finished, when I went back to the recovery mode, TWRP is lost, and the recovery goes back to stock recovery. Every time I start up/reboot my phone, I always get the DM-Verify warning.
Anyone can point me why after flashed the 4.1.3, my recovery goes back to stock recovery?
Also, which method should I use to change the stock recovery to TWRP & bypass the DM-Verify warning?
Thanks in advance
As for the TWRP, after flashing with TWRP you have to boot into Recovery and root (SuperSu/Magisk).
Only then TWRW sticks.
As for the DM-Verify, there is a thread here how to do.
Honestly, the DM-Verify doesn't bother me, so I don't bother to remove it
Cheers

Thanks for the answer, . Actually when I flashed with 4.1.3, it came from the Experience ROM, ver. 17. After flashed with the stock 4.1.3, when I went back to the recovery, the TWRP is gone, replaced by the stock recovery. I thought that when we flash via custom recovery such as TWRP, it will bypass to flash recovery, CMIIW.
When you flash stock ROM, the image will contain the stock recovery, so you will need to reflash twrp from fast boot

Booting up default ROM, it will make sure recovery is original and if not it will restore it just like it did for you. TWRP rooting will remove the original recovery making it impossible to break TWRP for you.

You don't have to. Just flash magisk or SuperSU right after the ROM, you will get both root and twrp

How to disable stock recovery

Hey guys,
I`m using x526. The other day I rooted the device with TWRP and flashed AOSP extended. But now I can`t seem to enter into TWRP. When I try to enter the recovery mode using the hard keys, it loads into the stock recovery. Even when using the option to boot into recovery in the AOSP extended restart option, it still boots into the stock recovery.So is there any way to remove/disable the stock recovery.Or even any other methods to enter TWRP?. I flashed the latest twrp (3.1.1) from the official site via ADB. Also AEX was pre-rooted with magisk

If your phone is rooted you can flash TWRP from app TWRP found in playstore

Twrp is already there, I can't just access it due to stock recovery. I flashed twrp twice and can enter the twrp just after flashing. If I exit twrp I can't access it again unless I reflash it

When you flash a new recovery the old one will be replaced. If you used the code fastboot boot recovery recovery.img the phone just boots to the recovery and not flash it. So please use the code fastboot flash recovery recovery.img.
