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.
I'll make new thread... sorry.. some members talking about mg2540s replacing dump of mg2570s, hoping some members had it already in this thread because the thread is old already.. anyway sorry, my bad.
I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
The SPI chip is an Winbond 25Q256JWEQ model (1V8).
The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.
I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6...
This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...
I'd like to read/write the contents of the eeprom chip.
This is located on the print head of a Canon inkjet printer.
It is likely that this disables the head after printing an xy copy.
Unfortunately, I can't identify the chip, so I can't read it either.
That is written on it: TO2 (T null? 2), KU
Does anyone have any idea what this could be?
Junior system administrator here (moving into IT with project management background). Long story short i need to get into the EEPROM on this tiny little thing (guess who's boss is too cheap to replace the mobo but doesn't have a datashest either... lol) .
Can anyone assist? I'm pretty OK with this stuff but IDing chips is a bit beyond me.
