[q] for entropy

---

Is there a script or app one can use to determine if their eMMC is damaged from previous kernels?

I don't think there is, and if it was, it would be unsafe. To see if the chip has bad blocks, you have to actually try to read them and if the read process for each block returns successful then the block is not damaged. But if the block IS damaged, then you won't get an error, the chip will just LOCK and you will have yourself a bricked phone.

Im willing to take that risk lol. It irks me thinking that im a flash away from bricking.

Its like having a few days to live and not knowing when its going to be over.

I'm in this situation too. I flashed the LPY rom and reverted to GB soon after that because of the battery getting drained too fast, AND because of this emmc bug..
The simplest way to do this, as I said before, is to have the /data, /system, /cache and /efs read (not sure about the latter, but I tried and it survived).
login as root in a terminal on your phone (I used terminal emulator), get root by using the "su" command, then type these commands, one at a time.

DO NOT USE THESE COMMANDS ON YOUR DEVICE! THEY WILL BRICK YOUR PHONE! THERE - I WARNED YOU!

time dd if=/dev/block/mmcblk0p7 of=/dev/null

time dd if=/dev/block/mmcblk0p9 of=/dev/null

time dd if=/dev/block/mmcblk0p1 of=/dev/null

time dd if=/dev/block/mmcblk0p10 of=/dev/null

The "time" in front of each command is just for "fun" as it will return the time it needed to do the operation, and it will also give you an average read speed result.

I did this on /cache and /efs but I'm not going further

One more thing - I believe the test will be more accurate if you add bs=1 after each command. Example:
time dd if=/dev/block/mmcblk0p1 of=/dev/null bs=1

This way it will read one block at a time, but it will take longer. Reading /efs on my phone (20 MB of data), it took 43 seconds at 475 kB/s speed. If you run it on /data, expect it to finish in 75 minutes. You can always check if the phone is locked by dragging down the notification bar. Also, I'm not sure if the device will just freeze, or if it will get stuck at the next reboot in case bad blocks are encountered.
Again - Please reconsider doing this, it's not safe at all!!!

*ALL OF THE ABOVE IS BASED ON MY AVERAGE EXPERIENCE IN LINUX AND THIS ALONE IS A REASON TO NOT TRY WHAT I POSTED!!

Interesting. But id prefer an answer without bold red text saying not to do it.

sorry mate, just copy/paste the commands in a notepad window and stare at them - they will look better. I thought you were willing to take the risk? Does having to read red text look more scary than bricking your phone? I suggest you leave this behind and enjoy your Note..

Youre right. My mood changed on the subject. Im crossing my fingers and hoping for the best instead. Thanks though.. :)
