This is just what i observed. I totally don't know if it is true that we have the same problem as the superbrick, but the evidence is "almost" undeniable.
I never had a problem as the superbrick. never had a galaxy or a device with it, so i know this only through research from the internet.
is an explanation. It has to do with the blkdiscard command. When the device performs a partition wipe, there is a chance that a sector will get corrupt (beacuse of bad eMMC firmware). Everything before the corrupted sector still will work. Everything after it is unreachable. We can reach it by changing the partition table, but there is no research in it for the Razr I.
This bug has only been seen in just a couple emmc modules. so it affects just some devices after android 4.0.4. And our Razr I can be one of them. The bug got introduced in jellybean.
The problem can be easy avoided with a patch in kernel/ext4_utils, not solved when it already happened. But i am waiting for 4.4.2 and see if it is still present in the firmware or i will contact motorola for it.
This bug happens it both unlocked as locked bootloader. U can't avoid it. U just are unlucky when u have it. And in almost all cases it appears only when updating your rom. So if u don't do anything to your phone, then the chance is slim.
I personally have wiped/flashed (for cm10) my device many, many times. And never had it. I just hope that it is solved with 4.4.2 so the chance that u get it will get even slimmer then it now is.
