Fix can never be created by anyone.

thank you for the fast answer, is it also not possible with jtag to downgrade the firmware? i have some basic skills in electronic and can do that kind of easy work but i have no knowledge abaout programming :-S

Downgrade to ... ?? All FW Vx.xx.02.xx - protected.

May be. May be will work as clp-365w if reprogram 2 dumps:flash and eeprom from clp-365w V1.14
But I do non have this dumps.

Need to test.

After reprogram only spi flash from clp-365w dump printer not work.

ok
i saw that now also that firmware is everytime above vx.xx.02.xx
ant then i tryed to find some pictures about the Motherboard ,that also don?t looks good ,they are totally different and use a different type of cpu so i think that porting the firmware would also not be possible :-(
how does it look about resetting the toner cartridge eeproms?
as the pinout of they ,they are only regular i2c eeproms and it should be easy to reprogram these when someone know what is stored on it
but unfortunately i have already tried to read from they and i cant get nothing out of it .
has anyone an idea of what i need to look when i'm reading ?
as reader i use a genuine TL866A from autoelectric.cn
and i tried a lot of different types of chips and even de soldered the chip from the mainboard, but nothing...

Main board is not different. And fw 1.14 from clp-365w work in c410w. But with errors and stopping.
Need test - reprogramm 2 dumps on main board.

Cartrige chip is not programmable.
May be will work compatible chip from 365's
