Thread: Convert 3790/3760/3750 to 3490

On my 3750, regions 45, 76, 139 to 143 are filled with FF only. Maybe try an erase on them? Make backups first!

Careful! We are in uncharted territory here.

Edit: region 76 seems to be empty on 3450 (0 byte in size).

After disaster when modifying region 41 I will wait for a while. Maybe there is a safer solution to recover HWID.
Maybe somebody know why I lost HWID. Maybe I modified somehow protected region 41 area?

All experiment done with 37xx or in 34xx?
I just realize the dump region 43 from same unit with different firmware is much different.

Yes, but during modifications I didn't change firmware for different units.
