For those who have been living under a rock, problematic leaked builds of ICS were released for several different Samsung devices a few months ago. Users of the Samsung Galaxy Note N7000 for instance soon discovered that their devices were being affected by what came to be known as the MMC_CAP_ERASE bug. Shortly after this occurred, XDA Senior Member hg42 came up with a way to revive downed devices.
Now thanks to some more ingeniuty on his part, hg42 has also developed a companion application known as Partition Scanner to assist in this process. The application features:
these allow fast scanning of all blocks of all emmc partitions in 1MiB steps.
The main purpose is to access each emmc block to find any bricked block in the partitions after repartitioning.
The “infinitely” variant runs checks infinitely, which may help to find emmc brick effects which only occur sporadically (if such effect really exists). Run this as long as you want. Reboot to finish.
If this freezes the last partition shown may have a bricked block inside.
these scan the whole emmc device.
emmc_find_brick_start starts scanning from the beginning of the device upward.
emmc_find_brick_end searches the end of the device and then scans downward.
If this runs up to the end or down to zero (showing a message with “completed –> OK”), no bricked block was found.
If it freezes, the block shown last with “…” at end of line is the first bricked block in that direction.
The line before with “-> ok” is the first usable block before/after the brick.
The application has received excellent reviews, so if you’re one of those people currently facing an EMMC issue, or you had the issue previously and gave up on your device, head on over to the companion thread and give this a go._________
