Did not realize ALL 8048s had nand lock, just assumed it was only the last few. You know what they say about assume making an ass out of u and me! In this case just me. If restoring a dump via ADB won't trip the self-destruct then the adb backup and adb restore commands should be safe also. It's just that more than half the time the backup halts prematurely and exits. And you cannot save the backup file to a FAT32 partition, it's too large. So the bulk of my advice is the same: read up first and follow the advice of the two main devs on this forum, Traveller1701 and Vampirefo.
