E92 Checksum error !!

[wesam]

Today i was tuning 2014 GMC Sierra 1500 OS 12663390
After modifying the torque model i tried ti flash the file but a checksum error occurred
I flashed the previous file back the flash process is complete successfully but after starting the car two error codes occurred U0100/P0700
cleared the code and it did not come back again for 30 min but i don't know what was wrong
looked in bug reports but there was no reports for this day

Thanks in advance

Did you try the file that failed the first time again? It may have just been something on the CAN bus messing up the flash the first time.

No i did not try
I was afraid that some thing bad will happen to the cutomer truck
but that is strange because it was the last table to modify
i left it to the end because i noticed in some E78 E92 it will close the throttle partially if increasing the torque models tables
