Hello.
My P6 shut down due to low battery an when I charged the battery my phone stuck at a boot loop.
I have TWRP recovery and I cant flash anything because of this error : E:Unable to mount '/data' .
I tried to flash stock recovery but always boot up to TWRP recovery.
Anyone can help?
Thanks
As you have TWRP & are rooted, you created a nandroid backup using TWRP, didn't you? If yes, have you tried restoring the backup in TWRP?

Unfortunately, I didn't create a backup...
Also I can't copy anything to internal storage.

Ok, just realised the P6 has USB-OTG support & TWRP has an OTG option (please view the attached thumbnails).
So just get a flash drive & USB-OTG cable (usually very cheap on eBay/Amazon/similar). Copy the file to be flashed to the flash drive, connect the flash drive to the phone using the USB-OTG cable, then flash the file/rom via the Install > Select Storage > USB-OTG option in TWRP (short video tutorial here).
When your system is up & running again, I'd highly recommend taking a TWRP backup to external SDcard every now & again at least, then leaving 1 copy on the external SDcard & transferring 1 copy to a separate external device (PC/Laptop/removable media/similar). As it is a full nandroid backup, it is very easy to restore the full original system as long as you can get into TWRP recovery & the backup is good (so make sure not to 'Skip MD5 generation during backup' & also have 'Enable MD5 verification of backup files' selected in TWRP > Settings).
I tried to flash from usb-otg and there is no difference from installing from external sd card.
I have the same problem! E:Unable to mount '/data'
I think you should format data partition before flashing. Try it with twrp.

Title says it all, I've on twrp recovery right now. I tried cwm before since i was having that problem. First time with Samsung any help would be appreciated.
Thanks
Edit: I believe one the phone is encrypted, the data can't be mounted to security purposes.

Same problem
I have the same problem. My device's (Samsung GS III VZW) internal storage is encrypted as well. Does this seem like this could be what's causing this?
I want to make sure that my backups are good that I'm taking with nandroid in CWM 6.0.1.2. If I choose straight up Backup & Restore -> Backup from the menu then I get an error:
Can't mount backup path.
If I choose Backup & Restore -> Backup to external sdcard, then it chugs along for about 30 seconds, then gives this error:
Backing up data...
Can't mount /data!
However, my backups that are put on the External SD Card (extsdcard/clockworkmod/backup/<datedfolder>) only consist of 3 files, boot.img (10mb), recovery.img (10mb) and system.ext4.dup (317kb). This doesn't seem right..
Any thoughts? Does this seem like it could be caused by the device being encrypted ?
Thanks! I'm a real noob and really appreciate the help!

Ya I say definitely stay away from encryption if your gonna flash roms. I've been here before backup what you need and wipe data in recovery. If it doesn't work flash the stock jb rom thatll wipe it.(located here if needed http://www.mediafire.com/?c3cj6udkai1ljhk ). As far as the backups go I believe that's actually the right size. Cwm uses a weird format for its backups now. Granted if data can't be mounted I think those backups are worthless now anyway
Hi,
I think my question have to be the thread in the Developer Section but I'm a new user and not allowed to post there at the moment so I have to write here.
I've rooted my I9195 and also installed the ClockworkMod Recovery v6.0.3.3 from arco68. When I want to make a backup the device offers me the option "backup to external sdcard" but selecting it brings the error "Can't mount backup path".
Is there any chance to solve this problem? I would like to have my backups on the sdcard and not in the internal memory.
Another problem is that CWM sets doesn't set the folder name correctly. On my Desire the folder was the actual date and time (e.g. 2013-07-26.08.33.25) but my backup from last week has the foldername 2013-01-01.09.14.57.
Regards,
Marco
I'll look into the backup thing.
The date/time thing is because your device didn't have it up to date when you made the backup. This device doesn't store the time between reboots afaik. To fix that it requires a change in the kernel, which I have already done in my custom kernel for CM10.1, but I can apply it to the insecure kernel as well.

I had the same problem. It seems that this ClockworkMod Recovery doesn't support exFAT file system. The phone formats my sdcard in exFAT file system by default. The solution is to format sdcard in FAT32 file system. I formatted my sdcard in FAT32 and ClockworkMod Recovery properly made a backup using "backup to external sdcard".
One can use EaseUS partition manager for Windows, or gparted for Linux, to format sdcard in FAT32 file system.
Flashed the latest stable Carbon rom yesterday and decided it wasn't for me so this morning I rebooted to TWRP and tried to run restore. The restore failed and the only error i see in the console is
Code:
E: error opening '/data/lost+found'
I went ahead and did the standard wipe (which also gave the same error, though it did not say failed) and rebooted, assuming it would just throw me back into carbon, but it got stuck in sort of a slow boot loop. I finally got back into recovery and now I'm at a bit of a loss. I saw only 2 suggestions, one being wipe /data and the other to flash back to stock with Odin. I'm not against wiping /data if someone could could either confirm that it would work or tell me if it's possible to backup some stuff from /data to my external sdcard or pc.
any advice would be appreciated, thanks
also sorry if this is the wrong place to post, I didn't see where else it would fit, says I can't post in the GS3 troubleshooting area.
ATT Galaxy S3
TWRP v2.6.0.0
fixed
Ok, I'm up and running again. I ended up formatting /data through twrp after I found out i could copy files over to external sd through its file manager.
so in case someone else runs into this:
assumes you have a twrp backup on the external sd
1. move important files with twrp's file manager to sd card
2. format /data
3. reboot recovery
3. standard wipe
4. restore backup from external
5. reboot system and cross fingers
Hello there,
I made the mistake of wiping the internal storage using TWRP.
I am unable to enter recovery mode with the button hold options (tried all variations). The only way I was able to get into TWRP was adb reboot recovery. adb connection is now gone and the phone is stuck at the boot screen.
I can get a fastboot connection and the bootloader is unlocked. So I flashed the boot partition with a stock boot.img and the recovery partition with a stock recovery.img (even though I can't enter the recovery partition).
the phone never gets past the boot logo. Is there a way to directly flash a system.img vie fastboot, so that the device can be used? I am kind of stuck here.. read several threads for the past 2-3 hours, tried to reinstall TWRP as recovery but cant boot into it, etc.
I downloaded the B510.zip and was wondering if there is a way to burn an .img out of that and flash the system partition. But maybe that doesn't make sense at all.
Any help is greatly appreciated
update
Alright then, I managed to boot into TWRP!! a previous version worked.
it shows: Custom storage (498MB), Internal Storage (0MB), External Storage (0MB)
i am now proceding to install the zipped 510 rom from huawei. unfortunately i must have lost my microSD so i am lefti with sideload and otg.
sideload doesn't work because i can't find my device with adb. only fastboot seems to work, i dont know the reason but i understand its normal for my situation.
i only have an unpowered otg cable. from what i read that won't work, but I'm giving it a try and currently load the zip on a usb flashdrive.
do i understand correctly that the overall storage just appears to be 498MB? my partition table must be fairly messed up if that is the case. are there other partitions not shown by TWRP?
what do you recommend besides/instead of getting a microsd?
kind regards
update #2
I managed to mount the internal storage as mtp and copied the zip into the pictures folder, because i had no writing permission for the parent dir.
i tried to install, but the first time i got an error that cache could not be mounted. i cleared the dalvik cache and retried.
this time i had another error message as you can see in the screenshot.
adb still does not work, so sideload is not an option. i can also mount the custom partition but it is just under 500mb while the rom zip is 7xx mb
any help would be greatly appreciated
Resolved
I managed to solve it. Installed the paranoid android rom from the pictures dir. it was under 500mb and worked fine.

You cant install Huawei Firmware with TWRP! Only Repacked / Custom Roms.

Hello,
I made a backup through TWRP to my lollipop rom.
Now Im trying to restore it and i get an error message - "no partitions to restore"
Any help please?
How did you make the backup? What did you check when creating it?
I made the backup through the twrp. i checked all the boxes (system,efs... )
Okay... Did you save it to internal storage, or sdcard? Also did you wipe your phone at all since the backup was made or before trying to restore?
On some TWRP builds, the restore option is not working properly. Do a full wipe and try restoring, if it does't work, you will need a clean install. Make backup of your data before this.
Also you can try updating the recovery image.
i saved it to internal storage then copied to external sd. after i installed other zip rom. when itreid to restore the twrp backup recognized by twrp but doesnt let me to check the boxes (system, efs...) as i wrote

Maybe the backup is corrupted somehow...
