Hi,
i want to format my /data but i can't because TWRP can not mount it.
I tried to change the filesystem to ext4 and format it but i stuck in boot.
It also says internal storage 0mb.
How can i fix that?
or is that normal with nougat atm?
yeah, I have the same problem. I think the L04 doesn't have a working version of TWRP.

same here! I tried to go back to EMUI 4.1 and use flash fire to update firmware without loosing root, it works all the way up to the EMUI 5 update then it forces me into TWRP to flash the file for whatever reason and then I loose root, and TWRP stops working properly.

hi,
I tried upgrading my tf300t from cm10.1 to cm10.2 . after a few failed attempts during which I am not exectly sure what I did wrong i got the device into a condition in which it only boots directly into CWM v6.0.2.3 without any option to do anything else. pressing power+volume down does not stop it from directly booting into recovery.
inside the recovery it says:
"E:Can't mount / cache/recovery/command/
E:Can't mount / cache/recovery/log/
E:Can't open / cache/recovery/log/
E:Can't mount / cache/recovery/last_log/
E:Can't open / cache/recovery/last_log/",
and i cannot mount any partition on the device. trying to access it from fastboot\adb has not been successful.
Any help would be appreciated.
thanks a lot,
guy
I now recall that at some point after trying to flash cm10.2 didn't work I tried flashing the offical asus firmware blob. after that the device successfully booted but when I tried to return to the recovery mode I still could not mount the /data partition. after that I tried some more flashing which brought me to the current situation.
new development -
after installing the universal naked driver i was able to boot into the boot loader using adb and I even can boot the device to the os, though no change when inside the recovery mode. if the device reboots it automatically goes into recovery and to reboot it I have to use adb again.

Flash the updated stock ROM again via fastboot to reset it back to stock. then flash the correct TWRP and then flash the CM 10.2 ROM you wanted.

I've tried that and the device does not seem to be responding to the idea. in fact I dont think it gets anything I've tried to flash at all. the files do transfer but do not seem to install. after starting a flash with fastboot the device stops responding.

plus, the bootloader screen does not show the usb icon at all. I am flashing when the device is in the bootloader.
at the bootloader screen there is a message: "key driver not found"

OK you said it can boot into Android though. Use terminal emulator to install the TWRP and then flash the stock ROM from inside TWRP. Just make sure the TWRP matches your bootloader.

That means you are on the 4.2.1 or 4.2.2 bootloader. That bootloader doesnt have a USB icon, it goes directly to fastboot if it is detected and that is completely normal.

Oh i thought you still had CM10.1 on it. Can you flash ROMs from that CWM or is the /data thing messing it up.

the /data prevents me from accessing anything on the sdcard so i cant flash anything from inside the recovery itself.
so, after doing as the guy in this thread - http://forum.xda-developers.com/showthread.php?t=2425581 says, I managed to make the device successfully reboot to the os by default and even make it reinstall the stock rom and than twrp recovery. the problem no is when entering recovery, it asks for a password which i do not know. when choosing cancel it gets me in but now it displays:
"E: unable to find partition size for /misc
E: unable to find partition size for /staging
E: unable to find partition size for /data
E: unable to find partition size for /recovery
E: unable to find partition size for /boot

E: unable to mount /system
E: unable to mount /cache
E: unable to mount /cache
E:TWFunc::copy_log -- cant open destination log file: /cache/recovery/log
E:unable to set emmc bootloader message

when trying to install a different rom the recovery mode fails to access the internal/external sdcard.
thanks in advance,

that means you probably flashed the wrong version of TWRP. Are you on the stock 10.6.1.8 or on a later version of bootloader? Those are different.

Use the 4.2 one. The jb will result in a very bad brick.

Hello!
Recently I recevied "Encryption Unseccesful" message on my phone. I tried to restore backup, but twrp says: "failed to mount /data". So, internal storage is dead. Found this. But cant find "repartition" menu in the cwm.
Questions is:
1. Do I need older versions of cwm to repartition sdcard? (If you have one, please share )
2. Is there any ways of recovering phone?
Thanks in advance!
no, just go to TWRP, Wipe, Format internal sdcard

tried this, but I think internal storage is corrupted. Is there a way to use sdcard as internal storage?
you can use sd card for apps and other stuff, but as I knoe cannot be used for system files
I made 2 partitions on sd:
4gb fat32
4gb ext4
But I cant bind /data to this ext4 partition. Can you help, please?
What i did:
With TWRP's terminal:
Code:
mount -t ext4 /dev/block/mmcblk1p2 /data
- Invalid argument (dunno why)
Code:
ln -s /dev/block/mmcblk1p2 /data
- but on phone boot i receive same "encryption unsuccesful" screen.
Edited /etc/fstab - same result.
Files and mount after reboot turn back to its previous condition.
Also installed stock ROM - same message screen.
[/QUOTE]
I got advice that i must do this things with init.d scripts. How can I do this? Already tried "xda's app2sd scripts" but they works if phone completely boots in OS.

Why not? I want only mount /data on sd without booting in OS. Other partitions like /system surprisingly work right, because i can flash ROM (stock, CM), but always receive - "cant mount /data"

try to flash stock rom with odin
Can't flash anything through recovery. (failed to mount "/cpefs" (Invalid Response)
I recently got this phone and I've been trying to install a custom rom, however, I can't seem to do anything while using TWRP. For some reason the file explorer shows no files and no /storage folder. It also says that the /system partition weights 0MB. I've already tried formatting the /data partition from EXT4 to extFAT, but it won't let me because it cannot mount the "/cpefs" partition, which I've been unable to find any information about.
I can flash the stock firmware trough ODIN, and I can flash the recovery. The internal storage works fine, but nothing shows up when I open TWRP.
I've tried formatting the data partition, repairing it, changing the partition format, wiping, installing a custom rom, installing superSU. But it won't allow me to do any of those things. Either "/data" can't be mounted, or "/cpefs" can't be mounted while formatting /data.

Which phone you're using?
J7 Pro?
Secondly make sure to enable OEM unlock options from the stock ROM's Developer option!
Thirdly check the recovery patches etc of the desired recovery's webiste (you're using) and flash it through the recovery if you're facing the problem!
It'll work, mostly some users said they fixed this by the above mentioned step!
If no luck, maybe someone will sort it out for ya, soon! :laugh:
Good Luck! :good:

Thanks for your reply. The model of the phone is SM-J710MN. The OEM unlock option is enabled, otherwise I wouldn't be able to flash the recovery. I am trying to use TWRP. Where would I find a recovery patch for this model?. Everything works fine in the recovery, but it won't let me wipe/format/repair or change ANY partition. It can't mount anything, and the error that I see the most often is that it cannot mount the /cpefs partition.

Hi All,
I am trying to root Samsung S7 Oreo 8.0 with TWRP & Magisk. But, when ever I log into TWRP it's saying "Inernal Memory 0MB)
I've followed below steps :
Installed TWRP and no-verity-opt-encrypt zip, it worked until I reboot to system
After reboot again the internal memory showing as 0MB (may be re-encrypted)
Is there any way that I can remove the encryption permanently?
Error :
Could not mount /data and unable to find crypto footer.

PS : I've gone through the forum to find different solutions, but nothing working to remove the encryption permanently.
yes, it is possible. is use it all the time with my stock android. give me some time to write it...or maybe someone other can tell u. u already used the search in this forum?
an other question, u really need an unencrytped internal memory?

Thank you.. Am not exactly looking for unencrypted partition. Am just confused whether it's expected to format data and no variety everytime or is it just one time for root?
Also I gone through the threads to find fix for this issue. But most of the people are suggesting to format data.
Any other better ways? Can we take backup of existing ROM from TWRP without root?

i am using a stock firmware by telekom, it installs some features after first flash and first reboot (maybe ur firmware does not need step 3, so my second reboot is ur first reboot into download mode)
1. flash stock firmware
2. first reboot
3. install for provider reasons and then
4. second reboot (important: into download mode)
5. flash twrp
6. third reboot (important: into twrp)
7. flash zip-file (attached to this post)
8. reboot and wait....
now u should have an unencrypted system. the only thing is, u need to repeat these steps on firmware updates.

Hello,
i Have recently upgraded to android 10. When flashing twrp i get a message failed to mount system partition. If i reformat system to ext 2 then back to ext4 i can mount system in twrp. When i re flash latest factory pixel 2 image and go back into twrp i can no longer mount system again. Is this some new thing with Android 10? Without it mounted i can not access my system partition with root explorer or other root apps. is there a way to force system to mount after flashing a new image?
After reflashing with magisk system was mounted somehow. Not sure how this happened.
