challenge: restoring VR on X930BT (and friends) (Page 2)

pionara, Thank you for taking the time to post this (as well as your other hacks/mods)

Have you been able to get a hold of an NDATA dump from a VR active unit (such as the Z130BT or the Z140BT?) and successfully restore VR on the X930BT?

Im curious to know where this project of yours is at.

UPDATE:

Spent some time looking at the schematic diagrams for x930bt vs x920bt vs z130bt. There seems to be some dedicated circuitry for the MIC portion that feeds VR circuit, which according to diagram is missing (not populated) on x930bt. I have not looked inside an x930bt, but this pretty much makes it harder to re-enable VR. Of course it is possible, but requires both hardware and software mods.

Hi Pianora, just for your interest, I opened up my unit today and swapped some resistors around to try to change the region code for the DVD player. So far though, I haven't noticed any differences and it hasn't changed the DVD region code.
