TWRP Install Being Rejected??

[Blenderite]

Hello,

I am new to this forum, but have done a bit of unlocking and installing custom roms on other phones (mostly OPO's, both my old one and friends). But this new OP 3T I just got is giving me some troubles I have not encountered before. I would LOVE to put this into the correct forum, but of course with my being new to this forum...rules...

I am following the standard install over on the TWRP site and on the OP3T, the install finishes and then I reboot and I get a screen that says:

"Your device has been unlocked and can't be trusted. If you don't want to see this screen, please lock your device by "fastboot oem lock" an erase userdata..."

I have never seen this before. Can someone give me a idea what could be going on here? Do I need to re-lock it? What did OP do to their phones!!?!

Oh and also, I am planning on installing LineageOS. Any reason I shouldn't?

Thanks!

Is nothing wrong with your device ..What you get is a warning that your bootloader is unlocked ...
You gonna get this every time you want to boot to your ROM or to twrp....
You can proceed further to install any ROM that you like...
I think you can find a guide on XDA forums to disable this warning if you want...

Ok I tried that and a new problem came up!! When I try to reboot into recovery, I do not get TWRP, but the stock recovery that was there originally! Unless they have completely changed the look of TWRP. I will try to upload a picture of it if that helps.

You can't get rid of the bootloader-unlocked warning without re-locking your bootloader, which you really should not do while you have a custom recovery installed.

Are you sure you've flashed TWRP and not just booted it it from a local file on your computer? Try using fastboot to wipe recovery first before flashing TWRP.

I followed the Fastboot method on this page (rules won't let me post the link normally): twrp. me/devices/oneplus3t.html

Right on that page (last paragraph of fastboot install method), you will see:

Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install.

I had a heck of a time with this myself (even reading the above). Even rebooting (after flash TWRP) to recovery (power+vol down), the TWRP install would still not "stick". Had to try multiple times. I also rooted with SuperSU 2.79 at some point in that process, which may or may not have helped TWRP to finally "stick".

I tried this once before, but after your suggestion to try it several times, it finally worked! Thanks!!

Flash TWRP, reboot, press the volume down key before the phone boots, go into recovery, you should see TWRP flash screen, that usually works but I'm glad you got it going
