Hello there. I just updated 9.0, but thanks in advance if I have a chance to unlock bootloader and root.
Well you updated for nothing.
Now you have to temporarily downgrade back to early Oreo. After bootloader unlock, then you can update back to Pie.
Root Sticky everyone should read:
ROOT YOUR V30!
Free advice: NEVER upgrade until you know root requisites. In this case you can still do the TEMPORARY downgrade back to Oreo for bootloader unlock with WTF exploit. But what if you couldn't?
You should check before updating to new OS, not after.
Same TWRP for Pie as for Oreo. V30 TWRP dev says it's stable and we're sticking with it.my bootloader lock is on but i couldn't find twrp and magisk for android pie my only problem was that i found beta, so i threw the phone many times format
