Hi.
First: Sorry My bad English.
So. The base is: FRD-L09C432 officially upgraded to Oreo. Data partition encrypted, bootloader and FRP unlocked status, TWRP installed and my phone rooted with Magisk. After some read in this and other forums I edited the phone fstab files, to delete data encryption. After edit this files I do a "Format Data" in TWRP. After that the FRP status changed from "Unlocked" to "Locked", and in Settings the "OEM Unlock" disabled and grayed. Bootloader status stay in unlocked. So this is the current state. The Recovery not changeable from TWRP to stock, because FRP-Lock status.
So, My questions is: How do I unlock FRP? If I rollback to Nougat, the FRP is unlock or not, or what? How do I rollback with TWRP? HurUpdater? What can I do, because if I rollback and FRP stay locked, I won't flash back the TWRP. And if this occur, I can't root my phone, and have other problems.
Ideas?
Did you try to unlock bootloader via fastboot?

Click to collapse
bootloader already unlocked. I won't try to relock, because 1 months ago I relocked, and my phone is bricked. Won't boot to system, and just DC-Unlocker helps to bring back my phone to life.
Good to know. I am also bricked but I was able to unlock bootloader via fastboot. I only have access to error mode.
flash via download mode and wifi
I lost my Widevine L1 when I unlocked bootloader and rooted.
How do I relock bootloader without resetting my phone and losing twrp and magisk?
You cannot do that. If you re-lock, you will loose everything.
Imposible
Relocking the bootloader automatically triggers the total wipe of internal storage (format the user data partition as well). This will make the phone exactly as it was when you pulled it out of the box. So there is no way to lock the bootloader and keep anything, nevermind keeping TWRP and root.
If doing what you're suggesting would be possible EVERYONE would would root and TWRP and remove the bootloader to have root and keep Widevine L1 security.
Hi, unlocking the bootloader will certainly wipe data. However, does re-locking the device do the same?
Yes
So I reset my Pixel 3 to factory image whilst having my bootloader unlocked, I then lock the bootloader and then it says there's no OS or Recovery. I can re un-lock the bootloader and everything is still there and working. Is there something I'm doing to get the device back to being locked and in factory state?
Hi, I have my fold 2 rooted with magisk and modules. What's the best way to unroot and relock bootloader ready for selling?
I'm thinking factory reset first then adb relock command?
All done. For anyone else looking to return to factory default.
I uninstalled magisk..picked restore images
Uninstalled magisk again...this time picked complete uninstall.
Then booted to fastboot.
Adb. fastboot oem lock
The phone rebooted by itself relocked and factory reset
