Hi, I'm also trying to unlock the bootloader of my t1020s but without much luck. I used AllexBast chinese guide and its .apk to get the signature.bin but the command "fastboot flashing unlock-bootloader signature.bin" always fails printing "fastboot: usage: unknown 'flashing' command unlock_bootloader". Did something similar happen for you? Any ideas? Thanks in advance.Thanks AllexBast I managed to unlock the bootloader, to flash TWRP and Magisk. The tablet is now fully rooted.
The part I don't "fully" understand is the ModSuper for gsi and the rest bellow.
This is for flashing another OS? I do this in TWRP right?
A correct image for example is lineage-17.1-20210808-UNOFFICIAL-treble_arm64_bvS.img.xz or even lineage-18.1-20210808-UNOFFICIAL-treble_arm64_bvS-vndklite.img.xz?
I have used an app that tell me that the tablet can use a AB and even a VNDK image, so I think they are the correct ones.
