We are continuing to dig for a solution but the issue is there is a unique identifier within the eMMC which is checked by the modem through amss.bin with an RSA certification. If this unique identifier is destroyed by user corruption (bricking the phone within that region) then there is currently no way to rebuild it. The most logical way to resolve this issue is to have a developer patch the modem/radio to bypass that check. It should be able to be done and is already being done on the N7100 and I9300 devices which were facing a similar issue...
