Is it possible to downgrade my bootloader from v3 to v1?
No and no, the token work inly on v1 bootloader if you update will lose unlock.
Before bootloader unlock might fail due to vbmeta and will lose current status by flashing full firmware. After unlock we can do it. I have patched firmware to keep same bootloader version safe but can be flashed after unlock
Hi, its in the 3rd post in this thread.@afaneh92 hi, ltns. long ago you unlocked my bootloader (S21+) and TODAY i took my tmobile phone to verizon. did not work at first, but fixed now.
long ago, i have tmobile carrier unlock my phone, so that was already done.
no problems with root all this time before today but today i flashed phone to U1, then factory reset. now, text/data/phonecall all work fine. but no root. bootloader V1
how to root phone again? i do not remember.... i guess i could do it with jrkruse? i just dont remember what i did and his thread is poorly written/confusing regarding individual steps. i still have your files/adb/odin/etc
baseband is G996U1UEU1ATLI
one problem that happens alot.. people do not know which file to put in which section of odin. why cant the name of the file.tar/zip always have this info in it.... xD
