I am a relatively new android user but do enjoy flashing roms, kernels etc
My problems began when i was trying to flash a new rom on my Nexus 5
I was trying to flash this rom http://forum.xda-developers.com/showthread.php?t=2655722 but despite doing a factory reset and wiping the dalvik cache and cache it refused to boot in to the new rom
I tried to flash the rom multiple times but without success, eventually when trying to boot into recovery to try again i was greeted with an unthemed TWRP recovery asking for a password despite the fact that i had a custom theme and multirom installed I tried to proceed anyways but was greeted with E: unable to mount storage
In desperation i tried to solve this problem and found this

TWRP asking for password
After unboxing my Nexus 5, here's what I did:
1. Booted into bootloader
2. fastboot oem unlock
3. Flashed TWRP v2.6.3.0
4. Booted to recovery
The screen that greeted me says "Please Enter Your Password".
I can hit the cancel button below this which takes me to the normal TWRP screen. I then pushed SuperSU to /sdcard, but when I flash it it fails because it's unable to mount /cache or storage.
When I reboot to the system, it takes an awfully long time (approximately 30s) to progress past the "Google" screen, and then it just seems to sit on the booting animation forever.
Any help?
EDIT: Solved my own problem.
Hit cancel at the password screen, then go into Wipe and then do a factory reset by swiping. Then go back into Wipe and press the 'Format data' button. You have to type 'Yes', and it will take a few seconds. After that everything should work normally.

I now fear that i maybe without both a rom and all my files such as my music that was stored on my phone.
Is there any way for me to undo the damage i may have done to to my phone?
You can't recover the data. But you can push files over with ADB.

hello there, i have a serious problem:
i had my a510 with unlocked bootloader and had the CM11 rom installed...so far, so good: all of a sudden when reading a PDF, it shut down, rebooted, went into a bootloop showing the acer logo.
i had also CWM installed, tried EVERYTHING there to erease cache and stuff like that..nothing worked it started flashing a different rom...no success...
i´ve already installed TWPR 2.7.0.0....worked until the point where i wanted to install a new rom...installing works, saying "successful" but in the lower left corner it says:
E: error opening ' /data/tf '
E: error: I/O error

can anybody help me please?! this is driving me insane!!
EDIT1:
i tried formatting DATA....after 5 minutes still no luck....it keeps "formatting data". could this be the reason for everything?!
EDIT2:
adb shell
recovery --wipe_data
did the trick!!!! i went back to TWRP, wiped DATA, no errors in /data/tf this time...clean installed CM11...and now it works again
Try to flash back CWM, format every partition (via the advanced menu)
and then flash a ROM like CM11

i have tried that...it didn´t work....it was stuck formatting...same went with TWRP....
only moving to ADB and sending the --wipe data helped me.
I've unlocked the bootloader, rooted my Moto G (xt1032) with superboot and installed CWM recovery on it. So I tried installing Cyanogenmod 11 (cm-11-20140405-SNAPSHOT-M5-falcon.zip at the moment) for my device and initially, everything works fine. It boots pretty smooth and downloads all the apps from the Google Play Store. But when I reboot the device I get the error "Unfortunately com.android.systemui has stopped" a few times. After clicking "okay" I get to enter my PIN for my SIM card, but then it just gets worse. The error pops up constantly and I have no possibility of selecting anything else. The apps on my wallpaper dissappear and appear again, the wallpaper switches to fullscreen, then normal again and so on. Wiping cache or dalvik cache does nothing, only a factory reset helps. Then it installs all the apps again, but when I reboot, the same problem persists.
Some threads suggested it may be an app and since it only happens when I reboot, could it be an app that launches on boot?
Others suggested trying an older version of Cyanogenmod (which is why I'm using M5 at the moment. M6 gave the exact same problem). Or has it something to do with the gapps file I'm using?
Any ideas on how to fix this? Thanks in advance.

Mine did this once and what worked for me was fixing permissions.

Tried fixing permissions before even installing any app. Rebooted, no luck. Still the same error without even a google account linked or app installed.

Do you remember which permissions exactly?

You need to do it from your recovery. In TWRP, there is a button that says "Fix Permissions." I'm sure it's available in CWM, as well.

CWM recovery didn't have a fix permissions setting, so I flashed TWRP through fastboot. Fixed permissions, rebooted: same error.
Did another factory reset and cache, sideloaded CM11 snapshot M5 and GApps to TWRP, flashed again. CM11 booted fine, just like it always does the first time. Had to reboot into recovery in order to fix permissions (wasn't able to do that right after I flashed CM). Rebooted again and still the same error.

Try manually wiping system, data, cache, and dalvik. If that doesn't work, try a different gapps package. If it still gives the same error after that...then I don't know.
I had the same problem : I just flashed cm nighglies instead and waited for one enough stable...
so i wanted to backup my oneplus one using twrp 3.0 and for some reason i decided to wipe the cache before i backed it up. I went to wipe (just the regular cache) and it kept trying to wipe but it never succeeded so i just forced rebooted it went back to twrp and backed up my phone. Once the backup was done i tried to boot it up and i was met with a boot loop. Then i kept rebooting my phone and no luck. then i tried to completely wipe my phone. well just a factory reset. it didn't work i was greeted with an error saying my cache is not mounted or something like that. so now i cant even wipe anything at all and i think twrp has a feature where you can access files from recovery and that doesn't work for me. adb isnt working either i was trying to push a file. What im trying to do is flash a newer version of twrp or try to adb sideload my same rom. but i dont have access to my same rom cause the links are down. my rom is minimal os btw. any ideas ?
Edit: I've fixed the problem by booting into fastboot and flashing a newer version of twrp 3.0.2. then i wiped the cache and it was successful. then i booted up and it works!
Hey there!
I have a problem: My wife's WIKO rainbow 3g suddenly showed this message:
She pressed the button several times, but nothing happened.
I booted the phone into stock recovery and tried to wipe /data, but then it says "mount /data error! Force format /data". It looks like it starts to format, but after a few seconds it ends with no message at all. Tried to reboot afterwards, but now it is stuck in the "Rainbow"-bootscreen.
Tried to update the phone using the WIKO software, but the phone isn't recognized anymore.
It's still on stock recovery, as it isn't rooted yet.
Is it possible to root the phone and install a custom recovery in stock recovery mode? Or is there any other way to make the /data partition accessible again?
