[Q] Partition destroyed after power loss

Hi everyone,
today i tried to update my CM11 to the newest CM12 Version. I booted into TWRP recovery and made a full Wipe. While doing this, my device had something like power loss, so the wipe could not finish.
Now the device doesn't boot anyway, after Power on it's booting into fastboot mode. The recovery isn't able to start. It is possible to use ADB and Fastboot. Using "fastboot boot /....../recovery.img it is possible to boot an recovery. The TWRP Recovery displays:
E:Unable to find partition size for '/recovery'
E:Unable to find partition size for '/boot'
E:Unable to find partition size for '/misc'
E:Updating partition details
E:Unable to mount '/cache'
E:Unable to mount '/data'
E:Unable to mount '/sytem'
...done
E:Unable to mount storage
E:Unable to mount /sdcard during GUI startup
E:Unable to mount '/cache'
Full SELinux support is present
E:Unable to mount '/cache'
E:Unable to set emmc bootloader message.
E:Unable to mount /'cache'
E:Unable to mount /sdcard/TWRP/.twrps when trying to read settings file.
MTP Enabled​
The "repair file system" option in TRWP Recovery doesnt work.
After several hours reading threads about similar problems i don't know what to do.
How can i repair the file system tables to reinstall the CM12 or any other ROM?
Hopefully

I think, i have an idea.
What about to rewrite the complete partitions on my Sensation using adb shell and then rewrite with the partitions? Could that work?
I read an article with an similar problem here: cyanogenmod.org
The problem was that I managed to screw up the partitions on my internal storage card, so basically nothing would work properly. I could still get into recovery, though. That's key.
Here's what you'll need:
Working recovery, basic knowledge of adb & the shell
Parted (download here)
stock PB31IMG.zip
Note also that I had run unrevoked forever (so my phone was S-OFF) ... I'm not sure if that's required or not.
So, grab parted from the link above. Now you need to extract the individual binaries from the .zip (the 6 files in the sdparted folder within the zip), ideally to your android-sdk\tools directory. Now push all 6 files (adb push [file] /sbin/). Next, we need to make them useable, so go into the shell (adb shell). Change to your /sbin/ directory, and run: chmod 0755 <file> on each of the 6 files.
Now, we need to fix the partitions. This is assuming that the partitions are there, just the wrong format (which is what happened to me .. I accidentally made them FAT32 instead of ext). So, run the following: parted /dev/block/mmcblk0 mkfs ext2. It will ask if you want to continue, hit yes. When it asks for the partition number, enter 1. Next, when it asks for the format, enter ext2. Let it do its thing. Now, once it's done, run parted again. This time, enter partition 2 (everything else is the same).
Once all that's done, your recovery program should be able to mount both the /data and /cache partitions. If that's true, you're pretty much done! One thing I found was that I couldn't directly install a new OS (I tried both Cyanogen and Ultimate). In both cases, it would look for stuff in the davik-cache that it couldn't find, so something wasn't installing correctly I think. So, if that happens, flash back to the stock PB31IMG.zip (put it in the root of your /sdcard/ and let hboot install it), and then root your phone anew. That's what I ended up doing.
Again, huge credit for this goes to -Steveo- and ciwrl for helping me figure out which partitions were the right ones (and for supplying parted, which I hadn't been able to find anywhere). If something doesn't end up working, just drop me a pm and we'll see what we can do.

Today i would need parted for ext4 partitions and i need to know where on the internal storage i have to write which partition. Is this a possible way to repair the partitions?
Hopefully

I'm having the same problem, my recovery log shows exactly the same. Have you found a solution yet?

Hi,
i am sorry, but i haven't found any solution yet. I am looking for an HTC Sensation to pull the emmc Data system Files and rewrite it on my broken HTC Sensation. I need the /dev/block/mmcblk0 etc. files to try. In my /dev/block/ folder are only "loop" files located, i think they are part of my problem.

[Solved][Q] Please help

I'm running cm11 and for a while I have had the problem that while in sleep mode my device will not wake from it so I have to restart my devive which hasn't been a problem until last night when my tablet rebooted and got to the logo the arrow will stop circling and then it will reboot. I can get into recovery but nothing I have tried has worked and I have looked around and I have seem some solutions that might work but for one reason or another it won't work or I can't do it so I'm starting this thread to see if I could get some solution that have step by step instructions.
I found this http://forum.xda-developers.com/showthread.php?t=2683787 but I can't figure out how to unmount data(if my data is even mounted) and I can get access to from my computer.
Please help.

Your cm rom mighy not be stable, ask from rom's original thread about issue, they should abswer pretty fast

Original thread? link please.

Either you are not on the right bootloader (unlikely) or your /data partition has some corrupt data on it.
Easy fix is to wipe /data from your recovery and reboot.

Thanks for the reply. I just went into my recovery(twrp [email protected]) and wiped data from within the advanced wipe menu(It said it was successful but it did also have some E:unable to stat stuff as well) and it is still freezing at logo and restarting.

That "unable to..." stuff is important. Post it please.
But probably you'll have to format data in recovery. Which can take 60 minutes or more. Let it finish!

Since you already wiped, formatting is the safest fix now. Otherwise you could have tried a filesystem repair from TWRP (also somewhere in the advanced wipe menu).
btw, "Please help" is a VERY bad thread subject.

Ok I will format then thanks.
What would have been a better thread subject? I'm new to this/don't do it very much.
Edit: I have formatted but got 2 more errors(don't remember exactly what they were but both ended with ERROR=255) but my tablet booted up into cyanogenmod just fine just have to set everything up again. I should be ok right?

A summary of your problem in 40 to 80 letters. You should also put more effort in punctuation and shorter sentences - your OP is almost unreadable.

I believe I know these errors, they are caused by a minor bug in TWRP and harmless. Your tablet should work now.

Thanks for the help with my tablet.

e:unable to mount /cache
e:unable to mount /data
Seen a few simliar threads.... but am going in circles.
i can get phone into Fastboot USB and access if from the pc via adb. they i am lost.
Any suggestions gratefully received.

Hi,
i also have this problem. See my thread "[Q] Partition destroyed after power loss" below.
It looks like a problem with twrp2.8.5.0. on the HTC Sensation.
I've got the idea, to create new partitions on the device, but i haven't the time to do it. If you get any results, tell me please :=)

I started a RUU of stock and it kept sticking a about 45% ......
All i can get phone to do now is switch on with HTC in the centre of the screen with a Triangle in each corner.
Vol up/down make no effect at power on.
If i try and run 4ext install from pc , it reboots phone and fails on "writing recovery" by saying "remote: not allowed"
So im sort of stuck now ...

Nexus 5 turns on but cannot access anything

I have a Nexus 5 rooted and running Catacalysm 5.1.1 Lollipop (Sep 27, 2015 Stable final release)
Yesterday while I was on my phone all of a sudden it froze for a couple of seconds and then restarted.
When it booted it says "To start Android, Enter your Password"
I can type in literally any password and it will go to the next screen and say
"Decryption Unsuccessful"
The password you entered is correct, but unfortunately your data is corrupt.
To resume using your phone, you need to perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up to your google account.

Then the only thing I can select is "reset phone."
The thing is I never encrypted my phone. I don’t want to do a factory reset as I have some things in my phone that I need
When I go into recovery this is what I get:
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’
…done
E:Unable to mount storage.

Also the internal storage shows 0 MB.
When I go into backup these are the sizes that are shown:
System (882MB)
Data (0MB)
Cache (12MB)
Boot (22MB)
EFS (6MB)
Click to expand...
Click to collapse
I’m using TWRP
I was wondering if anyone ran into this issue or knew anything about what is going on in my phone.
Is my phone dead? Can I get it to work again? Is there any way I can access the internal storage and retrieve my files?
Any help would be appreciated. Thank you
