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

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.

I Think my Internal sdcard is corrupted!
Please Help! Reflashing android won't work. I think the partition is corrupted!
Device: Google Nexus 5
Original OS: Android 5.1.0_r1 (LMY47D)
Recovery: TWRP 2.8.6.0
One day I turned my phone off, and later i decided to go into recovery. I believe I went inside Advanced Options and clicked "Fix Permissions." Then I proceeded to reboot. I was busy at the time, so when I remembered about my phone, I saw that it was still booting. It had been at least 30 minutes so I knew it was in a bootloop. I decided to go back into recovery and reflash the system.img onto it. No luck. I realized I had to try flashing the entire Nexus image (using the flash-all.bat). The phone would still not turn on. I tried flashing different versions of android, and here are my findings:
Android 5.1.0_r3, 5.1.0_r1, 5.0.1: all cause my phone to not be able to boot up (stuck on the 4 color flying animation)
Android 4.4.4, CyanogenMod (cm-11-20141008-SNAPSHOT-M11-hammerhead.zip): Allow my phone to boot up.
However, after I found that I could boot onto Android 4.4.4 and CyanogenMod, I realized that I could not get access to the sdcard!
Here are my findings:
When I go to the phone's root folder, I see a FILE called "sdcard"
When I go to \storage, I see a FILE called sdcard0
When I open camera, the app crashes (possibly because it stores pictures on the sdcard).
I tried to delete these files when I had root access with CyanogenMod but the file manager said "can't delete file." When I am in recovery mode (TWRP) however, I can see the sdcard folder and the contents. Just through every system boot, the sdcard is inaccessible.
After I realized that the problem wasn't due to the data on my phone (after flashing many system images), I realized my data partition might be corrupted. Then I went to this site and followed the directions: http://forum.xda-developers.com/goo...o-repairing-corrupted-data-partition-t2577447
The e2fsck command didn't do anything as cmd said "The superblock could not be read or does not describe a correct ext2 filesystem."
Afterwards, my friend told me to try mke2fs /dev/block/platform/msm_sdcc.1/by-name/userdata
I typed that in adb shell and something happened. I started processing blocks or something. Unfortunately now, I am unable to mount the data partition at all. I am also unable to flash the userdata.img onto my phone through fastboot.
UPDATE: When I open up twrp recovery and look in the log I see the following:
E: Could not mount /data and unable to find crypto footer.
E: Unable to mount '/data'
E: Unable to recreate /data/media folder.
Updating partition details...
E: Unable to mount '/data'
E: Unable to mount '/cache/
E: Unable to mount '/persist'
...done
E: Unalbe to mount storage.
E: Unable to mount /data/media during GUI Startup.
E: Unable to mount '/cache'
Full SELinux support is present.
E: Unable to mount '/cache'
E: Unable to Mount '/cache'
E: Unable to mount /data/media/TWRP .twrps when trying to read settings file.
E: Unable to mount '/data'
MTP Enabled
Anyone know how to fix this? Please help, I owe you so much if you can solve this! Reply to me if you're able to help, I'm also new to xda so I don't really know how messages work. Thanks!
Try taking it out and putting it back in. It happened to me too.

By sdcard I mean the internal sdcard (/storage/emulated/0). Nexus 5 does not have an external sdcard slot anyways.
So you are saying you have no apps, no widgets, nothing... /storage/emulated/0 is your main storage which INCLUDES your system files (unless you have a phone or tablet that has a separate internal SD card - would be /storage/emulated/1 ... I am guessing)

I just want to ask if you're experiencing blinking android on stock recovery.My phone is Huawei y600-u20 dual sim smartphone, MTK6572 CPU. At first bootloop i tried flashing using update.zip on stock recovery and it works fine but after installing camera 360 lite, my phone boots and it's stuck on the logo and when I tried to enter recovery mode the android logo with no command keeps blinking, I can't execute any command. I tried reflashing the same rom i flash at first bootloop but it didn't work anymore. I also tried reflashing it with other stock roms and still no luck.
One time, I flash it with a new backup ROM from my friend where he was using CWM recovery, after i access the CWM recovery,
this is the message i got
E: Can't mount /cache/recovery/command
E: Failed closing /dev/misc (I/O error)
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/recover/last_log
E: Failed closing /dev/misc (I/O error)
Couldn't open directory
No files found.
i try to mount emmc but it says error mounting emmc.. the same when i mount cache, data, etc. the result is always ERROR mounting emmc, cache, etc.
If you have any idea, please do help me how to fix it.

Hi,
As there isn't a dedicated forum for your device here try posting your query is in:
> Android Development and Hacking > Android Q&A,Help and Troubleshooting.
You can hopefully find some support there.
Good luck
After the update of two Magisk scritp my telephone on reboot is stucked on logo.
By long pressing Vol Up + Power I can enter in recovery or fastboot mode.
I need to recover my data, I found a TWRP recovery that was ported to this phone but it is unable to decrypt my data.
I was able to perform a dump of all the data following this post:
Backup full firmware(ROM) of any MediaTek device using MTK client| Oppo reno6 5G | MT6877​https://forum.xda-developers.com/t/...sing-mtk-client-oppo-reno6-5g-mt6877.4406069/
When I boot in TWRP the recovery say:
Could not mount /data and unable to find crypto footer
Failed to mount '/data' (invalid argument)
Unable to recreate /data/media folder
Unable to mount /data/media/TWRP/.twrps
Failed to mount '/data' (invalid argument)
Failed to mount '/system_root' (Permission denied)

Can somebody help me to correct the TWRP?
If I reinstall the OS with SP flash without deleting the user partition could I have access to all my data?
The system use an MT6873 chipset
Thanks
Reflashing an OS doesn't affect the user-data stored.
Reflashing change nothing, the phone is always stucked on Ulefone logo after reboot
