Re: T2 Chip Programmer Tool
Not keychain or cacheOriginally posted by curiositymasterI guess it relies on information stored in some cache (I guess keychain). This looks interesting.
The owner info is stored in a file called "FMMAccount.plist.plist"
and yes it is .plist 2 timesComment

by acedogblastThis 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... -
by baletakHi,
had T490 with faulty bios chip. Bought chip out of ebay and soldered on. Laptop starts and works however serial numbers of laptop and motherboard do not match.
I have updated laptop model number.
1) I did not find the way to update laptop serial number - I have this one.
2) I dont know where to get my motherboard serial number and how to update it. Is it somewhere physically on the mainboard? How do I update it?

Many thanks

After adding the chip save the xml file and copy it to the root directory of the...-

by TeslaI was wondering if you more experienced technicians could help answer some basic questions I have ... and help me build a reliable work-flow for using my new XGecu-T76 Chip Programmer (running XgPro v13.17). I like being able to leave the chips soldered-in (when possible) and read/write them with pogo-tool.
As instructed, for more reliable operation with pogo-tool, I have backed the SPI-Clock Frequency down to 16-Mhz (and that seems to be working fine so far for reading/erasing/writing/verify).
So, let's say I have a MB that soft-bricked itself after a common BIOS-Firmware... -
