I am trying to relock my bootloader but, this z2 play had Oreo update in August and a security patch later than that. None of the firmware shared on this forum allows bootloader to be locked, it always fails saying downgrade of security.
Does this mean anyone on latest security updates cannot lock bootloader? If there are no firmware to avoid security downgrade, we are stuck with unlocked?
The latest firmware I can find is OPS27.76-12-25. This is April security patch. Before I unlocked this device, it received a security patch after the Oreo update which was probably the one above.
Can we downgrade security level in order to lock bootloader with April firmware?

Hi there.. yesterday our device got android pie update.
So i was thinking is there any way to revert back to oreo
With security patch before august..so that we can unlock the
Bootloader.
I have seen nokia 7+ has an option to revert back to oreo with april security patch and so they can unlock the bootloader.
Can we do the same for our device??
how do I bypass the RMM on Samsung A5 2017, so that it can be installed TWRP & Root
Do not turn off or restart the phone for 168 hours and just use the mobile data
Hi guys,
I have an AT&T G8, network unlocked, and running the July 2020 Patch (G820UM20r). My question is: Is it possible to unlock its bootloader without having to brick it? My goal is to crossflash it in order to get recent updates, etc.
Additionally, after crossflash, can the boot loader be relocked to get DRM widevine level L1 ?
as stated in the title on my s20 plus (SM-G968W) there is no toggle for OEM Unlock, its been a long time since ive tried to root and from what ive been able to pick up from googling is it may not be supported for my country or cpu manufacturer. ive tried the change date and time trick that every guide suggested and it did nothing.

What is your baseband version?
If I recall correctly, you must be on v1 bootloader (pre Mar 2021 security update) in order to be able to unlock.
See this thread on how to unlock the bootloader (paid service):

i cant downgrade to the original bootloader?
I do not believe that it will allow you to downgrade from A13 to A11. You could try and flash G986WVLU1CTLB (A11) via the patched Odin, but no guarantees. It may also wipe your phone, so make sure that you backup before you try.
Patched Odin can be found here:
