For some reason, out of the blue, I cannot read/write//mount my internal storage. I installed an unofficial version of CarbonRom on my Verzion M8 and everything was PERFECT! I created a Nandroid Backup of the way I had my CarbonRom setup and installed CHECKM8's aosp kernel to see if it would boot. It did boot, but was crashing all over the place. So naturally I went back into recovery to just restore my backup and all my internal data was gone. I've tried many things and I haven't been able to get my data to mount again.
HELP! As my phone sits right now, its a brick.
Basically, how do I restore access/mountability of the /data?
I tried fastboot erase userdata but it can't mount the data to erase it.
Going to try flashing the stock RUU and see if that'll do it. Currently downloading.
This happened to me also and I flashed the RUU but even after that data still doesnt mount. Did you find a solution
I had the same thing happen to me and with multiple flashes it just fixed itself. I had some ROMs saved to ext SD which saved me.

CWM recovery 6.0.1.0 was not actually wiping my partitions before I flashed new ROM's I found out recently after installing TWRP. Eventually (after a few ROM installs) my phone started bootlooping and hanging a lot, so I wiped everything in CWM and attempted another flash. Now the sdcard portion of the internal memory seems to be corrupted, and it won't mount or be written to when I flash (via fastboot or CWM).
Any tools you know of that can help me format or repartition the internal MMC so I can try to flash it again? Or at least get it back to stock form to turn it in to the Sprint store and see if they will help me. Maybe it is physically damaged, but I am leaning towards corrupted.
Sounds like a job for Odin.

I have S-On. I'm running the latest AOKP build for my phone. All was well but I wanted to flash MIUI Rom. I flashed the boot.img and then tried to flash the rom. I use TWRP. I wiped the cache and dalvik as usual. I have been flashing roms for awhile now but not the MIUI one. When I did the phone rebooted in to fastboot mode. I tried to go to recovery but my recovery wasn't there. I was able to reboot my phone and the AOKP rom was in tact and appeared to be running even though I tried to flash the MIUI. I navigated to ES file explorer and is says the SD card isn't mounted. Everytime I try to boot to recovery my screen goes blank and I have to use the power button depressed to get it to restart. I then used fastboot flasher 2.4 to try to flash the TWRP recovery again. It appeared to take and I got the words fastboot USB. I thought for sure problem was solved. After my phone rebooted again the SD card wasn't mounted and still isn't. I am able to use the phone and AOKP seems to be running as intended but the SD card won't mount. After I flashed TWRP again it still doesn't boot into recovery. I get an EACCES permission failed when I try to move anything to the card or try to access it. I tried team Nocturnal's method for the SD Fix but it didn't work. Am I going to have to flash an RUU file? If so, where can I get that from? Any help????
It looks like your sd is corrupt. Did you factory reset in bootloader? You didn't mention doing a full wipe when you flashed the ROM, you only mentioned cache and dalvik cache, you should always wipe cache/dalvik cache/factory reset in recovery when flashing a ROM. Also, which MIUI did you flash?

I dont believe I did. Using trwp promts me and i follow that. Now i cant get to recovery or flash it. Any other options?

You might need to RUU but I'm not even sure if that's going to help with your sd problem. It's worth a try though. Run the RUU, flash TWRP, format your sd card. Make sure you have s-off before you run any RUU though or you'll brick.

I cant seem to get s off. Not sure i want to go that route. Any other way to get it working?

Hi,
I installed CM 10.2 on my A510 to try it out, did a full wipe, and got stuck in a boot loop. Wiped again and reinstalled but had the same issue. I have tried again with CM 10.1.3 and the AOKP roms but have the same issue, full wipe before each install. Right now I cannot get past the boot screen where the tablet restarts and tries again and again and again etc....
Any help would be welcome.
Thanks
When you say Full Wipe, it means Factory reset ?
Did you try to restore a Backup with CWM or TWRP ?
Yes factory reset. I tried restoring with CWM but each of my backups fail to restore either failing to restore /data or /system.

Did you try to copy your zip file both on internal and external sd card ?
checked MD5sum ?
Did you try to flash a stock ROM from Acer ?

Yes to all the above. Did the stock ROM one hour ago and doesn't boot loop buts just sticks at the iconia tab logo. Also when I try to get recovery now I just get a dead Android picture.
Edit: Using Stock ROM I get a message that Android is upgrading Optimizing aa 1 of 46, 2 of 46, 3 of 46 and it then retorns to the iconia tab logo and stays there
I finally got the tablet working again by installing the original ROM using fastboot for each of system, flexrom, boot and recovery. I then installed 10.2 which works OK apart from the fact that when using Titanium to restore my apps the tablet reboots randomly. So far I've only managed to restore 10% of my apps.
EDIT: Constant reboots now regardless of what I'm doing, downloading, installing etc. Going to try another ROM, 10.1 or AOKP. On 10.1 now, restoring apps from Google works for a while but after a certain stage random reboots starts again.
Lastest, back in endless boot loop. Tried restoring by fastboot but flexrom restore fails every time.
I have a similar problem on my A700... Installed 10.2 and then suddenly did not boot anymore. Tried to flash the nighly before the newest one but id did not change. Then i made a backup in CWM and formatted DATA. Now i boots but if i restore the backup, it won't boot. I can find my files in a 0\0\0\0\0 Folder or something like that. So nothing is lost, but it's not in the running system.
How to restore these files and apps?
After at least 25 wipes and flashing various roms 10.1 10.2 and AOKP I think my tablet is reasonably stable now. I formatted - /data /system /flexrom internal storage, everything except the external sd a few times then installed and have only had one random reboot since 2am. Instead of restoring from titanium or direct from Google I reinstalled all my apps individually and the restored my data from titanium. Hopefully this will be the end of this.

So, firstly I'd like to explain a bit about my device.
It's currently Rooted, has CWM installed and it's on Cataclysm Rom.
When in recovery mode, it usually takes longer than it used to when clearing the cache. It takes 4 mins???
When in recovery I install roms for this device, they usually don't work. I wipe data/cache. and install the .zip.
It boots, sometimes it doesn't. Sometimes it loops.
Then when restoring the backup I had made. I boot into recovery mode, and go in restore backup it says. E: Cannot mount Storage.
I leave the Nexus for a day whilst switched off, then go into recovery it mounts storage... Sometimes it doesn't detect it, sometimes it doesn't.
So my question is, is my phone damaged in any way?.
Try twrp

If you want the CWM UI, go for Philz Touch!

Maybe your partitions are screwed up somehow. If you keep having issues, grab all your stuff off your internal SD and back it up one of the times it does boot, then use the factory image from Google to flash back to 100% stock. Factory reset in stock, then redo everything from scratch and try using TWRP. A hint to, in TWRP in settings check "Use rm -f instead of format". Tends to give me less issues.
So I just went into recovery (buck's twrp) to flash me some aosp, it worked fine but I forgot to get a gps lock in sense before I flashed so I went into recovery to restore a nandroid and I got the dreaded "unable to mount /data, and unable to mount internal storage. Tried reflashing buck's twrp in fastboot and no dice. I have the RUU downloading although I would hate to have to go through that. Any recommendations? I;m going to try flashing philz recovery right now

Just plugged it into my pc to try to flash philz and a pop up came up saying that the file system is currupt. Ugh. I'm so p/o'd right now. Is RUU my only choice right now to repair this if any?
Just flashed RUU. Same thing. Going to dry formatting in windows device manager now

In TWRP go to Wipe < Format Data and do that and it should fix your /data problem. Before doing that I recommend just using the advanced wipe and ticking /data /cache /boot & /system and then re-trying. Also afterwards a good ROM to start with would be Cyanogenmod, I've had the least number of problems with that than any other, especially when helping people with issues like this. I actually had someone who's only way of fixing his issue was flashing that.... odd I know but that is why I always recommend it after having this issue.
Edit: just seen you've did an RUU and your problem is still persisting, I still recommend doing the 'Format Data' option in TWRP, this is known (at least to me) to fix most if not all problems with mounting...
