9S12XEQ384 1M12S READ/WRITE/ERASE HELP

[468]

Hi.

Dashboard: C1BT-10849-EXN
Car: Ford Fiesta 2014 (ECO Boost)
MCU: 9S12XEQ384 (1M12S)

This dash can read only with external power +12V on dash.
So i read the emulated eeprom with UPA, i change it and i write it back, but the old data remain.
The write was succesfull.
Always i keep a full backup from Emulated Eeprom, D-Flash & Full Memory.
After many tries i get FSTAG error from UPA.
I try to read EEP but was empty. The same for D-Flash.
Seems like that partitions was deleted.
Now i try to "Partition D-Flash" to erase the chip and re-programm it with the backup files, but i have "System Error: 997" from UPA.
Also i try the X-Prog to erase it (non-secure & secured) but with no success.
The only settings that i set for Partition create was for eeprom 16x256 bytes = 4KB (4096 bytes)

Any advice how can i restore the backups to MCU, with the help of UPS or X-Prog?

It's urgent...

Best regards.

There can be problem when erasing flash data . I dont remember the hex address but I know that erased flash MCU become SECURED MCU.
Try to connect to the MCU with secured option and come with resuts.
