Firmware on Samsung SL-C460FW, C460, C460w. Reset chip in color Samsung
You need to have programmed flash memory
For C460FW
For C460w C460
Picture1
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.
Picture2
Unplug all wires off main board. Unscrew the four screws on the edges of the Board.
Picture3
On the front side of the Board we may be interested only EEPROM 24С512.
Picture4
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.

Check the efficiency of the device(scanner, Fax, wifi, ADF paper). Assembly printer case. Device is ready.
