[Q] Error mounting /data - Defy Q&A, Help & Troubleshooting

Hi guys,
i installed CM10 on my defy today. The problem is that i can`t download things from the play store to my defy because it tells me that there is not enough space on my phone?! I checked the mounts in the recovery menu and i saw that the "data" is not mounted. And if i try to mount i get an error: "Error mounting /data !".
What i have to do to mount the data?
Thanks for your help!

Hi there!
I got the problem solved! I just flashed my phone with an original firmware and did the rooting etc. again. Now, everything is mounted correctly!
greets!

Hi,
even I am facing the same problem. Can you please let me know in detail how did you reflash your old firmware and how the issue was resolved? Thanks in advance.
Regards,

Just flash sbf and root your defy again. It would solve your problem.
Cheers !!!!

[Solved] Encryption Unsuccessful Fix

Hi,
I tried to install CM10 on my Motorola Defy+ (MB526), which was successful to some extent.
When I tried to install the latest gapps through CWM, it froze at the starting applications part.
I force restarted it, seeing that there was no change for a while.
When I restarted the phone, it kept on rebooting, with limited functionality, so I downgraded to CM9.
An error message pops up which says with Encryption Unsuccessful. A reset button was available, but didn't help.
I then re-upgraded to CM10, but the phone has limited functionality.
After researching the problem, I realised that the /data partition is not mounted as it is probably corrupted.
Is there any fix to this problem? Will flashing a sbf recreate the /data partition?
Please advise as the phone is basically useless without /data (no apps and constant reboots)
Thanks,
neiljain

Hi Buddy,
I went through the same process last evening, earlier i was on 2nd boot then it was very slow hence I decided to move to CM9 for better UI and good battery life. but while doing so my phone also got encrypted.
I did following and installed CM9 yestrday night.
Removed SD card, read it through computer (CArd reader) and put CM9 in one folder along with GAPPS.
Charged my battery till green light pops up.
Entered the SD card again and then started the phone in Custome Recovery.
Full data Wipe
Dalvik Cache wipe
Install CM9 and Gapps.
again clear Cache and dalvik and reboot.
It should work, let me know if it doesnt work post that as well.

Hi,
If the /data partition is corrupted (which I believe it is), will this still work?
Also, did you get any "Can't mount /cache/recovery/command" errors in CWM at anytime.
Thanks,

remove SD card, log into Stable recovery mode. wipe data / factory reset and try rebooting.
if problem still persist, read your phone through RSD and flash CM7.2 file. let me know if you need link for the same.
It will work.

This will format your data partition, be warned!

Boot to recovery and turn on adb (in Advanced). Open a shell on the phone through adb from a PC. Try to find out if data is mounted, and if so what filesystem type it uses:
Code:
$ adb shell
~ # mount|grep /data
/dev/block/mmcblk1p25 /data ext4 rw,nosuid,nodev,noatime,nodiratime,barrier=1,nobh,data=writeback 0 0
If /data is corrupted it will not be mounted. On my phone /data and /cache are formatted ext4, which is only supported in the latest CM10. If yours happens to be formatted ext4 as well and you want to go back to CM9 you'll have to reformat both to ext3. If /data is corrupted you can also reformat the filesystem as you don't seem to have data worth keeping on it anyway (seeing that you talk about doing a full SBF flash to 'recreate the /data partition'). This can be done manually or - if you have not nuked the scripts installed by CM10 - using one of the scripts made for that purpose. Those scripts live in /system/bootmenu/script:
Code:
~ # ls /system/bootmenu/script/|grep format
format_ext3.sh
format_ext4.sh
If you have access to these scripts you can just run format_ext3.sh to reformat /cache and /data in ext3:
THIS WILL FORMAT YOUR DATA PARTITION - ALL DATA WILL BE LOST!
Code:
~ # /system/bootmenu/script/format_ext3.sh
If you don't have access to them you can achieve the same effect using the following commands:
THIS WILL FORMAT YOUR DATA PARTITION - ALL DATA WILL BE LOST!
Code:
PART_CACHE=/dev/block/mmcblk1p24
PART_DATA=/dev/block/mmcblk1p25
umount /data
umount /cache
# if you want to check the filesystems you can run these commands...
#/system/bin/e2fsck -y $PART_DATA
#/system/bin/e2fsck -y $PART_CACHE
# to format the filesystems to ext3 use these commands
/system/bin/mke2fs -j $PART_DATA
/system/bin/mke2fs -j $PART_CACHE
mount -t ext3 -o nosuid,nodev,noatime,nodiratime,barrier=1 $PART_CACHE /cache
Once you have formatted /data and /cache you should be able to install CM9 - no need for any SBF flashing unless your phone is really messed up (as in 'deleted the stock kernel' or something like that).
THIS WILL FORMAT YOUR DATA PARTITION - ALL DATA WILL BE LOST! Or did I say that already?
No matter. THIS WILL FORMAT YOUR DATA PARTITION - ALL DATA WILL BE LOST! Just to be clear...

Hi,
Highly appreciate your efforts.
I am new to Android, so could you please explain what "adb" is.

SBF flash and data wipe in stock recovery should work too...
The other method is a bit more nondestructive, but probably harder for you

Hi,
I tried flashing DEFYPLUS_U3_4.5.1-134_DFP-231_CN_SIGN_UCADEFYEMARAB1B50AA009.0R_PDS03C_USAJRDNGIBRIRD15_P015_A030_Service1FF.sbf.
The flash was successful, but the phone looping the boot animations, not actually loading Android.
I have also lost access to CWM and recovery.
Please help.

adb is the Android Debug Bridge, a program running on both the phone as well as your PC which makes it possible to access your phone (through either a command line shell or some GUI-thing layered on top of it).
Are you also new to Linux and/or computers in general? In that case you're probably better off flashing the phone as detailed, even though that takes way more time and does involve more risks. If you feel comfortable running commands from a command line I'd advice you to install the ADK (Android Development Kit) on your PC, get adb working and run the commands as I explained. That way you regain access to your phone without all the hassle and risks involved in flashing all the way from SBF. Both methods work, so the end result should be the same.
I'm intentionally not going into excruciating detail on the task of installing and running adb as I don't think you should use your phone as a guinea pig to start experimenting with adb - for that use the emulator which comes with the ADK.
Success
Hi Everyone,
Thanks for your very helpful suggestions.
I was able to recover my phone after flashing the SBFs
Just to be on the safe side, I will stick with CM9.
I will also post the instructions on XDA for other people who have the same problem.
Once again, thanks everyone,

Njoy your Defy.

Unable to mount /system, Error mounting /system!

So guys, I downloaded the latest CM nightly through the CMupdater app, I rebooted into recovery TWRP 2.6.3.0 at that moment I think, when I tried to flash my update it said "Unable to mount /system" and just stood there, I rebooted into recovery again and tried to mount it from the mounts menu without result.
Next I updated to the latest TWRP but the problem persisted, changed to the latest CWM and that too, is unable to mount /system displaying the message "Error mounting /system!"
I seriously don't want to lose my data as this was a simple update so I didn't make a backup but I don't know what the hell else I'm supposed to do.
Oh and BTW, trying to boot to system leaves me at the Google screen for an indefinite amount of time.
Thanks in advance
Edit:Turns out formatting system doesn't delete my data, I got impatient and did that, problem solved.

Can you add SOLVED to the thread title..
Glad to see everything is ok :good:
Thx Josh
So, i just started getting this same error after updating to TWRP 2.8.2.0, I tried wiping the system and still got the error? I downgraded to TWRP 2.8.1.0 and wiped system again, and that seemed to fix the issue. Not sure if it was my own bug or 2.8.2.0 but just wanted to leave feedback for the next person who may be searching for help.

Razr M E:UNABLE TO Mount Data , System , Cache 0MB

Hi All , So recently ive been out of a phone and my cousin was nice enough to give me a broken android which he said , If i can repair it i can keep it . So i think its easy enough to fix its just a boot loop ill just flash CM As it has TWRP Already
Not So easy... I go to TWRP with some ROM's Pre-Downloaded onto a SD Card and go to flash them when i notice when i try selecting a partintion it says 0mb , Think maybe its just a weired temp bug and flash or atleast try to flash a new rom and keep on saying the same sadly
E; Unable to Mount Data
E; Unable to Mount System
E; Unable to Mount Cache This has been going for about a few weeks now with no avail and think this would be a nice forum to ask for some help , Other things to add are...
When its on normal boot its a boot loop
When i try using RSD To Flash Stock its still on the CM 13 Boot Logo loop
I also tried Upgrading the TWRP Version and Flashing CWM But still no luck
Any and all help is apreciated thank you all !!!
Anybody!!!?

Does this method removes or wipes the current OS? I have Lineage OS installed and as on installing the OTA update through TWRP. there is this error which states unable to mount storage. I really don't wanna format wipe my data. Any help would be appreciated. thanks
Have anyone wipe everything before proceeding new installation.?
I had this Mount issue few minutes back and luckily i found this thread..And yeah repairing the mounts did worked out for me.
Thanks to Hitler_72485.
And yes! It will format everything.
I fell into this when i was doing normal wipe of partitions to install new rom, strangely it got struck while doing format..So i removed the battery and came up with those mounting issues. which ever partition i tried to wipe, mounting those failed afterwards. Then i tried this repairing thing with EXT4 FS. now everything is fine.
I did faced problems while repairing few but i did a normal repair swipe and then selected EXT4 swipe. (Don't know exactly what i did)
Hope No one will have this problem again. unless its a diff. case..!!
See ya.!!
