Some of you maybe know, it is possible to read out the config file from a board with a working chip using the USB005 I2C adapter and IR/Infineon software called PowIRCenter. The software is available freely at Infinion...02-10-2025, 04:52 PM -
I need maintenance utility for T580 to write serial number,

If anyone has a full dump of this model (or a compatible one like MFC-J485DW or J885DW), or knows a private Discord or Telegram group where this kind of firmware is shared,...07-05-2025, 10:53 AM -
Hi,
i unlocked my T590 with SVOD4 and wrote new ec from lenovo site. Now password is gone but dmi is missing now. So i have to write it back with Thinkpad Maintenace Utility.
I now have newest version of lenovo U1 golden key software (3.5.52) for USB boot stick. This tool starts the Thinkpad Maintenace Utility V1.20.
But i can't initialize eeprom. It says: "ERROR: Written data is unmatch."
So i can't write sn number without initializing it first.
Any ideas? -
