Part 2 of a three-volume RAR archive holding auto-patch firmware for model A315F, binary revision 2 (BIT2), Android 12. The package is described as a four-file set, typically meaning separate bootloader, AP, modem and CSC images flashed together. Being patched, it differs from stock and is used for specific repair or service procedures. Parts 1 and 3 are needed to unpack. Check the current bootloader binary on the handset before flashing and keep a backup of NV and user data.
