Downgrade firmware?!
Does anyone know how to downgrade the firmware to 1.00 version(it's currently running with 1.09)? I tried to follow the instructions on Mutoh website. But it keeps showing me error message. I called Mutoh they said you can only upgrade not downgrade. But I'm pretty sure there is a way to downgrade it. Because I have done it with another 1614 and it works fine.
Hi Ernest, how did you do it with another 1614?
which program did you use?
is downgrade procedure the same and applicable to all different models or is it specific for each diff model?
I have vj1304!
Anyone with any luck/info as to how to downgrade mutoh printer firmware? pls let me know a.s.a.p
the hard way I could only think of
1. removing icc bios chip off main board
2. use eeprom device to install specific desired firmware on new icc bios chip
3. solder new programed icc bios chip onto main board
NB.have only actually seen this being done on laptop mother board
would this work...anyone?
