Today i managed to unlock a Opel Touch & Connect satnav (BOSCH 7 612 830 110).
The device was locked after 3 wrong PIN attempts:
By erasing the sectors #265 and #266 via JTAG the devices makes some internal FSCK after poweron (this takes up to 10 minutes, so be patient and WAIT) and the code dialog is back again:
This should also work for NX and MCA with the same sectors and for FX maybe also but a lower ones...
