Tools being used:
Tunerpro RT
OBDLink Lx
Ls Droid
2003 LM7 PCM with bench flash harness

So im switching the 2003 OS to the 2004 OS and .bin. Using Tunerpro i only changed the VIN due to not wanting to change everything before even getting a successful flash.
Every time during the write it would get a crash randomly between 3xx - 502 blocks. Looking at the bin this entire section is just padded with "ff", so no actual info being stored here.

Realized during the write that it was going too fast and there was some bus collision happening. There is a setting that will disable write compression and boom it worked.

Just wondering if anyone else has ran into this problem before?
