Sharp LC-55UB30U (AmTRAN board 0171-2272-5895 / 3655-1092-0150, MStar MSD95C0H, panel AUO T550QVN03.0) - bootloader alive, need true MstarUpgrade.bin or eMMC dump
TV boot-loops on Sharp logo (5 cycles then shutdown). Menu inaccessible. Official .utv updates (v1.13, v1.16) on FAT32 USB are ignored - they're the app-level format. Key finding: with a file named MstarUpgrade.bin on the stick, the TV freezes dark at power-on; remove it and it boot-loops normally - so the bootloader is alive and scanning USB for that exact name, it just rejects the .utv contents (encrypted BDC/CDB-wrapped segments, not MStar script format). Main firmware corrupt, bootloader healthy. Need a real MStar-format MstarUpgrade.bin or full eMMC dump from a working LC-55UB30U (any UB30U size probably usable). Can anyone share?
