Let's start updating firmware with disassembly printer. Unscrew the two bolts left on the back cover and pry the latch to open side cover. And we will see an exact copy of the device 3305 series.

 On the reverse side of the Board is easily recognizable NAND-flash which we must to reprogram. Carefully unsolder it using a soldering station. Clean the PCB from flux and dirt. Clean the legs of the chip and insert it into the programmer. Using configuration "default" check flash on bad blocks and if we're lucky, and the chip has no bad blocks we can at once reprogram fix-firmware. Otherwise, it still makes sense to try to flash the chip. If the "bad sector" is on the first third of the chip, the device probably will work. If that doesn't work then you need to change the chip or reshape the firmware, by sliding the block of data that which gets on bad sector, on at 0x21000 bytes and mark it in the table of "bad blocks”, either manually or using a special program to convert the firmware. After flashing and checking chip install her back on the main board. Check the quality of the soldering, wash the flux.
