[Q] Devlog partition corrupt - can be removed? - HTC Desire X

Hi all,
a friends Desire X took an unfortunate swim in a washing machine. Since then, it will hang with a black screen with backlight on about four times a week, mostly when it isn't actively used. /proc/last_kmsg contains:

So it seems it gets an I/O error while writing to /dev/mmcblk0p28, which is devlog, AFAICT the internal logfile HTC uses for service requests. It then wants to reboot but crashes during reboot because the eMMC isn't responding at all anymore.
Now my question: Would it be possible to remove the devlog mount? I haven't tried yet since this might lead to a bootloop, and I wanted to ask here for experiences first. Any hints greatly appreciated, also maybe other approaches than removing devlog?

[Q] Phone crashed last night - last_kmsg included

Currently running CM10. I woke up this morning to my phone being off, booted up and pulled last_kmsg. I leave my phone charging every night, this is the 2nd time this happened in a week (last time was Friday I think, I forgot to get last_kmsg then though). Here's the end of the file which I think probably contains the important bits, but the entire file is also attached.

Random reboots caused by SD card I/O problems

My phone keeps randomly restarting for the last three months with ROM Slimbean 0.1 flashed. Usually the phone restarts, when the display is off, but sometimes it restarts out of blue.
After getting the kmsg log, found out, that it might be related with the SD card. The SD card itself is ok, verified with scandisk & the socket seems to be ok, as it always properly mounts after reboot.

I have Link2sd installed, most of my apps are linked to the second partition of the SD card.
Ist it always the same sector?
As an sd-card is extremely cheap, I would replace it to try it.
With scandisk you mean the crappy windows tool?

[Q] Damaged EMMC? Is booting from SD card possible?

Hi!
I have a problem with my HTC Desire X. The device was ok until it went off and was plugged to a power source, then only the HBOOT menu appeared.
The device has not been touched concerning custom roms, boot loaders etc. until then. So it had the stock rom and as far as I know, there was no update going on, when the device turned off.
To solve the problem, I unlocked the bootloader and installed the recovery image TWRP 2.5.0. But in the Recovery mode I could not mount any internal partition. So it was not possible to wipe anything or install a custom rom.
The only explanation I found for this is, that maybe the internal memory (EMMC) was corrupted and the system could not mount it and boot up. My question is: Is there something I can do to about it?
It would be nice if I could boot up an Android system from SD card. Is this possible? I only found solutions for other HTC devices so far.
I did some more research.
First I tried to start fdisk/parted to print the partition table. Both did not work. parted hangs, while fdisk says it could not read the device.
So I looked what I can find with procfs. There are only four partitions printed.
Code:
cat /proc/partitions
major minor #blocks name
179 0 3784708 mmcblk0
179 1 20 mmcblk0p1
179 2 544 mmcblk0p2
179 3 4500 mmcblk0p3
179 4 1 mmcblk0p4
Code:
cat /proc/emmc
dev: size erasesize name
mmcblk0p17: 00040000 00000200 "misc"
mmcblk0p21: 00c7f600 00000200 "recovery"

mmcblk0p31: 46800000 00000200 "fat"
mmcblk0p29: 00011c00 00000200 "extra"
Then I tried to find out wether there were error messanges concerning the emmc:

I see some I/O errors there.

Dead embedded MMC ? Can I recover some of the data ?

Hello,
my i9300 has been rebooting strangely in the past days, and this morning was stuck in boot loop. Unfortunately I didn't get to backup the last pictures I took. I am trying to find a way to get access to the data it might still hold.
I can enter recovery mode (works but sometimes requires several attemps). Once there it cannot read system partitions (and thus can't wipe cache).
I tried to remove battery / sdcard, hold power button for a long time, hold it with home + up as well

What are my options ?
* I've seen some people using JTAG software tools and soldering to reset the eMMC. E.g. http://forum.gsmhosting.com/vbb/f60...n7100-without-removing-emmc-pictures-1945278/ Are there a combination of these operations that might allow me to read without destroying the data ? I also read http://forum.xda-developers.com/galaxy-note-2/help/to-recover-data-corrupted-emmc-t3292290/page2 but was not 100% sure of how to use that.
* are there some soft solutions I should try before I do this ? Maybe reflashing recovery software? Some magic combinations I don't know ?
The phone has
* CWR v6.0.4.6
* BlissPop 3.6 (if I recall long time since I set it up it.)
Thanks anyone for their help.
Yes you can get the data from it, if it's hardware-dead then no, your best bet is JTAG, I'm sure it won't be too expensive
