[Q] Can't mount /data after Quarx's CM 10.2 - Defy Q&A, Help & Troubleshooting

After installing Quarx's CM 10.2 october 30th nightly (defy, not plus) the device seemed to be working normal but I then soon noticed that no internal storage is detected. (meaning I also could not install apps from the play store) Upon restarting, I go through the entire 'first time' sequence again and any thing I did before I restarted was not saved. I think this is because, when entering TWRP and going to mount, data is the only partition that it will not allow me to mount. Attempting to wipe the data partition yields the result 'unable to mount /data'. Is it possible to mount somehow in adb or terminal? Is anyone else having this issue? And is there any known fix?

Well , I had this problem too , but not with this ROM , enter in Motorola stock recovery , and make a wipe , after that , you should flash again a SBF , and put it again.. , or if you can still flash something , try to flash the 10.2 CM again.

But it won't let me. :/ Like I said before, attempting to wipe the data partition just gives me 'Unable to mount /data'. Does that mean the partition is corrupted, or can it be mounted somehow in the terminal? This has really become a headache...
As an update, I actually was able to wipe in the stock recovery, but going back to TWRP now shows that both my data and cache partitions cannot be mounted (or still corrupted). Would flashing a new sbf fix that? I can still access cyanogen if I boot normally but it is the same as before, no internal storage and nothing is saved after reboot.

Did you try to wipe data and cache in stock recovery ? I don't know if you will flash a SBF will fix that , try to wipe data and cache too , and after that if you can't boot , flash a SBF.

error mounting /data- brick? LOL

I tried reflashing a sense 3.0 2.3.3 rom because of some minor issues. Now I may have nuked my /data partition. first it wouldn't format so I pulled battery numerous times. and Mounted it through mounts and storage menu, then I hit format, and it formatted, so I hit mount again and flashed the rom. and when I restarted the phone after splash screen the phone restarted and went into recovery
Tried everything including mounting /data again and it keeps saying error mounting /data. am I screwed?
I have .2007 eng bootloader btw. shoud I try the pd15img?

I don't think you need to do that. You could do a fastboot erase, then go back into recovery and wipe data to reformat it /data, effectively starting from nothing.

Now I am getting mount /cache errors. aww man I think my phone is done....
edit: used the pd15img and I am back on stock :| s= off but I have the stock bootloader wtf.... how do I get my eng bootloader back?
this is how I fixed it:
I was on eng bootloader, but then I got reverted back to the stock bootloader.
This is how I encountered the problem. first of all I was having issues with raffy's fusion 3.0 rom, so I decided to reflash it, but it wouldn't flash or format /data, then I mounted it to through mounts and storage on the latest cwm 3.0.2.4 and hit format.
After that I tried reflashing his rom, it flashed but, after splashscreen I was redirected to my recovery instead. that's when I freaked because when I tried mounting data it said error cannot mount /data. so I fired up adb and did fastboot erase system -w and it erased it including cache.
then I popped up into recovery and BOOM started having cache mount errors experienced by a lot of people lately.
I thought I was SOL, but nope I downloaded the pd15img from http://www.megaupload.com/?d=V4NAODYZ
and put it on the root of my sd card and it worked....
so if anyone of you dudes are having similar problems try that ^

[Q] Bricked SGS

I have a SGS that does boot, only thing is i flashed the phone like 20 times with KIES and Odin, also re-partitioned the thing, still its leaving al the apps and setting.
When its done booting and going into the wizzard is give the error "UIDs are inconsistend" and shows the "I'm feeling lucky" button.
i have tried everything, but i cant fix the problem.. i also flashed the phone to 2.3.3 and than flashed a pre-root kernel with cLW recovery and formated everything, still everything is still on the phone, even when i connect the phone trough usb and format the internal SD and disconnect the phone, everything is still there!
Any ideas to fix this or is it just a hardware failure?

Can't mount sd? Go to recovery, take your sd out, and put it back in. If that works, you try flahing the custom partition again (not the original partition). After that, try flashing a rom.
Edit: but try to flash the original again first. Make sure you flash it, reboot recovery, flash it again, reboot recovery, and then flash your rom.

[Q] A200 data wipe failure -- no longer

Hi all,
I tried to update the custom ROM on my A200, but in the process, the data wipe failed.
What I did exactly, is use ROM Manager to load the latest JellyBean CM ROM for A200, selecting the option to wipe the data partition (do a factory reset). My device rebooted, and it started trying to wipe the /data partition, but it just stopped right there. No error or anything, the system just hung there for 2 hours before I turned it off. As I feared, the system was rendered unbootable.
However, CWN Recovery *is* still available, which I guess is a good thing. So, I can boot in recovery, but I can't really get it to function. I tried formatting the data partition again - system hangs. I tried installing the image from sd card - system hangs.
Does anybody know how I can recover from this? It seems to me that there's nothing *really* broken, just that my data partition is corrupt somehow -- and I suppose there has to be a way to recreate these partitions.
Thanks!
I've had CWN Recovery run for 24 hours now, and still nothing. It fails to format the data partition.
Anyone knows how to tackle this problem?

[Q] TWRP backup fails on data partition "E: Unable to stat /data/data/../cache/ .. "

[Q] TWRP backup fails on data partition "E: Unable to stat /data/data/../cache/ .. "
Whenever I try a full nandroid backup in TWRP it always fails once it gets a few hundred files into the data partition. However, it does complete the backup when the data partition isn't selected.
When I first start the backup a bunch of different red error messages come up for various cache files in the data partition.
"E: Unable to stat '/data/data/[variousapp]/cache/[stuff]/[hashvalue?]' "
I've got a rooted T-Mobile Note 3 with Jedi Elite ROM and TWRP 2.8.1.0, however I'm not completely sure that my phone is legitimately rooted. If I try to open the SuperSU app it says "There is no SuperSU binary installed,...", and applications constantly achieve root access then get denied it moments later. Or sometimes the applications achieve root access with no further issues, it's quite random.
Does anyone have any idea what could be going on?
EDIT: It also should be noted that the files in the error messages can be found when using the TWRP file manager, but when using any file manager application with the OS booted the "/data" folder appears empty.
Anyone have any idea?
Thanks
Well.... from the top of my head I would try to do these things:
1) install one of those "check to see if I am rooted" apps and run it.
2) flash a kernel that has been prerooted, i.e.:that it installs the SU binary to the appropriate location.
3) flash one of those .zip packages in twrp that root your phone.
4) check to see if you can make twrp install root for you ( i think when it doesn't detect root binary it offers to do that).
5) reinstall rom only part as a last resort?
Once you restore proper root access you might need to restore proper SELinux labels to /cache /system /data.
Let me know if you get to this part and need specific instructions.
Best of luck

I flashed the latest SuperSU.zip and that ended up fixing root access. The Root Checker app verifies it as well as other applications being granted root access.
I tried flashing CF-Auto-Root in TWRP and it fails.
How do I restore the SELinux labels for those directories?
You caught me on my way to bed but here are the instructions:
From terminal or adb shell
su
ll -Z
(check for any "unlabeled" text for /data /cache /system)
restorecon -Rv /cache
restorecon -Rv /data
mount -o remount,rw /system
restorecon -Rv /system
mount -o remount,ro /system
ll -Z (you should not find any "unlabeled" /cache /data /system)
Let me know how it goes
I tried all those commands from the terminal and it still shows all of the same "Unable to stat" error messages when backing up
The "ll -Z" command, is that supposed to be double pipe or double L? I'd never seen a double L command before so I couldn't get it to work if that's what it is.
Sorry to budge in but I have the same problem too on my oneplus one. Everytime I do something in twrp it saids unable to stat /data/data/com.android.chrome/something I wiped /data and it still does that. I tried to install custom rom and when it starts it saids something is wrong with my system udi and com.android.phone keeps on crashing. So I don't know how I am suppose to fix this. If I format /data I will lose all my pictures,music,apps,etc. since it will wipe /data/media? Any help?
Edit: Upon reading the first post again, I also can't perform nandroid backup because it fails at /data. Which was why I wanted to try different rom and wipe /data to see if it would be fixed.

alright i said screw it and wiped internal storage and it fixed the issue. i had to push ROM onto the new storage through ADB but it seemed to fix the issue.
For anyone who is wondering you need to do a FULL wipe (ie in recovery wipe EVERYTHING including internal storage), then push or mount devices through recovery and put ROM back onto SD card.

Well you fixed it the easy way, I went to the thread on how to turn oneplus one back to stock.
http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541
I unzipped the 44s Stock ROM and manually flashed each file via adb to it, that cleared up all my problems. I did lose some data, at least at had my apps, messages, and pictures backed up.

I have this same problem with my OPO and I tried a full wipe including internal storage, but the "unable to stat..." problem still persists. Should I try using the "Format Data" option on TWRP instead of just the "Advanced Wipe"? I tried searching online for the difference but I can't really find any information.

So I had my issue on my OPO also, still never confirmed what the actual issue was but after some googling I saw this thread and maybe one more with the same error description.
From TWRP I went Wipe->Advanced Wipe->Clicked ALL boxes.
From what I could tell the issue is actually on the "internal storage" partition which is your emulated SD Card.
I'm not actually sure what the "Format Data" option does tbh I never had to go that far.
Word of warning, make sure you have ADB working and you know how to push files to your phone. You can in theory use the "mount" option from TWRP and connect to a PC as an extendable drive but this functionality is super flaky and is known to not work on occasion.
you don't have to!!!!!!!!!!!
actually i formated it and i was looking for a way to transfer my zip file to internal storage ........... but when i clicked on backup/restore it started to install and booted normally !!!!!!!!!!!!! (by temp boot file)
Sad I am also facing this problem too. At last I have to format everything to get my phone working again, wiping /data does not work, must wipe /data including media.
Internal Storage failure?
This happens to me all the time all of a sudden. I did not change anything at all, except for flashing a new CM version.
I also get a strange stat error, something with google.photo cache.
Yesterday, I have then flashed the new 2.8.6(7) and that gave my phone the rest. It might be because I flashed through TWRP itself into the recovery partition, but now additional to the backup error above when I want to erase dalvik cache, the recovery just hangs. I also can't restore a backup atm.
Now I have reflashed the real 2.8.6.0 recovery and it still hangs when I want to wipe dalvik... wtf is going on here?
And oh yea, my phone does not boot anymore either, it just loops at the flash screen...
UPDATE:
After I found some info on this thread about similar issues, I factory reset my phone with stock recovery (TWRP was not reliable anymore, even the 2.8.6.0 version that was running perfectly before) and then reflashed the latest CM on a wiped internal storage. Now I am up and running again with minimal loss of data due to my TB backups that are scheduled and save to the SD.
But this leaves a very weird feeling back, basically my phone was rendered useless out of nowhere (I was running the previous CM for 2 weeks already), making TWRP backups impossible and forcing me to wipe the internal storage with all media on it without giving me the chance to back it up (MTP in TWPR was also very flaky and died several times half in copy operations). Something is going very wrong with this phone, never ever had that on any of my 5 previous htc devices and the fact that the OnePlusOne users are among the main ones that reported similar issues, I have a feeling it is linked to cheap storage quality. Motorola is a Chinese company now after all... :-/
Hello,
I had the same issue with my Galaxy s4 GT-I9500, it said "E: Unable to stat /data/...", wiping didn't fix, but after I run "format data", it fixed the issue for me.
I have been going through the same issue. I can fix it for 'a while' (by wiping and formatting data) before it comes back again. Anyone knows how to get rid of this once and for all?
