Update: looks like these 408rt have a limit on read and write. backstory I had purchased a new 408rt ic last year. it worked in ch413a programmer a few times then suddenly it cannot be written anymore(it can READ "successfully" though the data field always says FF FF FF FF.... then last night my old working IC was already at 8600 prints so I decided to dismantle and read the IC again(backup the 8600prints bin file) then re-write using the same bin file above(around 8500 prints) so I can deduce from the data field what was the difference. temporarily I had to re assemble the printer using...

This is my bin file for mg2570s with main board QM7-4706.
bin file details: prints are already at 8500+. has a ink absorber full error at first bootup but it can be cancelled by long pressing the color or black button and printing can still be done. I am using a refilled ink cartridges.
bin file was read using CH341A black. and I was able to successfully re-write on the same IC(because the replacement IC I purchased suddenly did not work)....

Same as the OP.

I tested this bin file on my mg2570s because I cannot find a bin file for this model. It was written normally. But there was a blinking light on the 3 orange leds(14 blinks). Google said ink cartridge not detected. Tried resetting the cartridge all same error. Decided to rewrite the old orig bin file with 8500+ prints and ink foam near full issue(still usable). If anyone wants a MG2570s bin file, I will try to attach here....

Hi new here. Was trying to find a bin file for canon mg2570s but found a topic here for an older model same ic but didnt work.
