Hello.
I need the correct USB recovery firmware (upgrade_loader.pkg) for:
Hisense 65A6500UW
Mainboard: RSAG7.820.7970 / ROH
VIDAA U3
TV is stuck in bootloop (Hisense logo → VIDAA logo → black screen → reboot).
Likely firmware or NAND corruption.
Looking specifically for USB recovery firmware (upgrade_loader.pkg) for this board family.
If anyone has a compatible dump or confirmed working firmware for RSAG7.820.7970 / ROH (K0316 family), please share.
