Zebong,
You should perform terminal command
F>R4
And then paste here result (A3 or A6?)
A3: App code damaged (BAD's in SA)
A6: Incompatible App code (PCB is incompatible)
If A6 - change PCB and see;
If A3 - you should find compatible Loader (same Eng Rev with patient) and load only App code.
Then F>j.
But don't write to SA anything (App code for example).
