Hello
current build number of my phone is
X680B-H6215EFIJ-Q-OP-200730V166
and build number before ota update is
X680B-H6215EFIJ-Q-OP-200629V139

I want to downgrade to version before ota, v139, but SWD tool gives sw version mismatch error. so, no downgrade possibility?
thanks

mismatch at vbmeta_system and vendor again
I try firmware upgrade to downgrade using SWD after reading several posts coz i think it safer than format all, now the phone back to red state again.
i dont have cm2 dongle or else, I ought to stop trying flash this infinix again in the future

UBL meaning Unlocked Bootloader?
