Bad EEPROM

[coppermine]

So I have this 1.1 that I replaced the EEPROM chip on at some point, years ago. I remember I did this because it was flashing red only. I don't know why I didn't try to just program the EEPROM, but I guess it doesn't matter, what's done is done. Anyways, years later I've dug it out and it still flashes red for bad EEPROM. I've built myself an EEPROM reader cable and tested it on some of my working units without issue. I can write and write the the EEPROM on this unit, and I've written a good EEPROM dump from another working 1.1 unit, but I still get the bad EEPROM flashing red led etc. Interestingly I can boot cromwell, but the video is all out of sync and it reports that the video mode is unknown. If I use xblast to reset system settings or manually change the video mode, none of it sticks after a reboot. I'm not really an expert at this sort of thing and I was hoping had maybe seen something similar.

Probably bad Tsop.

This error is the same for bad eeprom or bad Tsop

For the video error i don't know what is it.

Load the eeprom.bin file into LiveInfo. LiveInfo_Beta_3-Xbox_v1.6-Yoshihiro.rar

Does it display an error when loading your red flashing Xbox's eeprom.bin file?

What values are loaded into its various information/settings boxes?
