"Before following these instructions please ensure that the device is currently using Android 12 firmware.
If the vendor provided multiple updates for that version, e.g. security updates, make sure you are on the latest!"
It said the latest, so I updated to the latest. Not sure if this is allowed, but I'll pay you money to help me get this fixed.
Brother, most rom are using based firmware C.48 as there latest not C.61. These instrucations are made way before C.61 was released.
I am going to be honest with you I have installed LOS 19.1 rom on IND model with C.60 last month with no problems, however, LOS rom is based on C.48 has there firmware.
Many developers haven't updated to C.61 yet. Even I am using C.48 now, and installed riceDroid rom with blu-spark kernel.
But bro, keep in mind one thing, none of the roms are stable. You are missing features like Dolby Atoms, OOS camera, Dynamic refresh rate, screen resolution change (except in Nameless).
I have used all the rom but again they are not stable compare to stock rom unfortunately, but keep your finger cross for updates to fix bugs and adding features.
