[1.1.2 OTB] HW Unlock > Testpoint Works, but can't restore to any baseband
I've managed to successfully unlock an 1.1.2 OTB iPhone (not the one i recently bricked), almost. After connecting the testpoint and running 'iunew' successfully I have been unable to write any firmware version successfully so again I have a 'repair needed' phone. However I was now able to downgrade to 1.0.2, manually jailbreak and activate it and have copied all the tools needed to repeat the operation.
This time 'ienew' fails with 'Can't write', and 'iunew' sometimes stays at 'Spamming AT, waiting for response' and sometimes it spits 'Did you erase the flash first?'.
Whenever I try to run bbupdater (be it with -v or specifying a .fls and .eep file with -f and -e) it says 'Error: Failed to initialize comm layer: (is it open by another app?)'.
Just to note: I have indeed stopped the CommCenter, and all the related files needed to do the unlock have the correct permissions on them.
Regards and thanks for your time.
