HELP with Colorado BCM eeprom chip was crashed

[minhhee2511]

Hi,
I tried to adjust the mileage on a Colorado 2011 which need to be done on Dashboard ( 93c56) and BCM ( 25LC040) according to Tachosoft. I successfully read/write on the dash chip but on the BCM chip 25LC040 gave me hard to of reading and writing over it with my Ch341 USB chip reader and Neoprogrammer. It's keep showing 000000 value on all fields and when i tried to adjust the hex code on 0800, I was not able to save the value. The I read the chip by a scanner tool and got a Bin file, then I was able to see the chip info, the I adjust the line as guided which is 0800 which mileage I wanted and saved it, then copy the file to the scanner and started to write on the chip. the progress was done easily but when I put back the BCM, the the dash show this mileage, and when I drive, no more km added, it just freezed at 999999, even with the Trip A/B, doest count km any more.

Has anyone suffered with this issue? Or if you have a solution, please kindly teach me. Much Much Much appropriate.

Thank you guys!

I tried flash the dash and BCM with original bin file, only dash work but BCM I accidentally lost the file because my laptop hard disk was failed. I searched on this forum a found someone posted a 2012 Colordo (mine is 2011) dash and BCM files, I flashed them but now the dash keeps showing 999999, and the remote key fob not working, also auto light not working. So depressed ! Do you have the original file of BCM for the model year? Please share with me. Or anyone have it, please help!

Thank you very much.
