Does anyone know whether I can crossflash this drive to a normal DVR-112.
Bought in China.
You can try with the TDB packages. However, better would be to post some info, eg. Discinfo output.
Here is Discinfo output
Nice. Could you also please post the info “dvrflash -v X:” gives you?
S/N not needed. 
Info from DVRFlash
Your burner is already a true Pioneer.
You can crossflash to 112L or A12 with Dangerous Brothers firmware…
Thanks for all your help
The difference between Axx/XL and 1xx/CH is the kernal type: GENERAL and PIO_ADV.
