Trying to install custom rom... when I go to the option to wipe data i get
--Wiping Data---
Formatting /data...
Formatting /cache...
E:format_volume failed to unmount "/cache"
Formatting /sd-ext...
E:format_volume make_extf4fs failed on /dev/block/mmcblk0p2

And then it stays on this screen, bout 5 minutes now. Is this normal?

I did unmount the system... I made sure all my mounts looked like the thread posts and then tried to wipe the data. I actually wipe the datda last. Am I still missing a step?

no u wipe data first - Put zip file in your /sdcard
- Reboot into cwm recovery
- Wipe Data/Factory Reset DO THIS FIRST
- Wipe Cache Partition THEN THIS
(Optional but recommended to prevent any minor issues)-Wipe Dalvik Cache from advanced menu in CWM
*Now before you Flash, Only if you are on the orange CWM, (Not RED voodoo CWM from Bali) if on red CWM ignore the mounts/unmount part*
MAKE SURE YOUR MOUNTS LOOK LIKE THIS: (Go to mounts and storage from CWM recovery)
UNMOUNT CACHE
MOUNT DATA
MOUNT SDCARD
UNMOUNT SYSTEM - this is the ONLY mount U SHOULD WORRY ABOUT

okay gonna try one more time tonight... had to odin so i'll keep you posted. And thanks for your help!

okay just to clarify, these are the steps i have taken so far.
1. used you tube link. how to root sidekick 4g + CWM all in one. (http://www.youtube.com/watch?v=wYC8XRqM-no)
2. Got CWM off the market and flashed CWM recovery.
3. Reboot into recovery. (Orange CWM)
4. Click the wipe data/factory reset.
And then that's when I get the screen promt I gave in begining post. When you say i have to format data. Do you mean go under mounts and storage and click format/data? And again I really apreciate your helpon this one. The SK 4g bugs are really getting to me...

i used super one click to root it then i used sduvick mod on link that n btw u got to have the krylon update n recovery files on the root of the sd card

n when ur in the orange cwm u go to wipe data/factory reset option n that should wipe it clean , then u wipe the cache n then you go to mounts and storage n unmount the system

so i have the update on the krylon thread. and i have android commander. when i tried topush the file over to the bin on the phone. it gave me a promt that phone must be rooted to access... but yea after goin into cwm and selecting the wipe data/factory reset. my phone just sits on that screen. i left it for an hour and nothing had changed. i'm really starting to get frustrated. thanks for all your help though. i gotta be missing something.

i would not used android commander if i were u

leave the update zip on the root of the sdcard n look in the krylon thread for n mod by sduvick

I'm actually gonna try and root the other way to get the red cwm. maybe i'll be able to fix the problem that way. thanks for all your help!

Unable to mount /data

I've managed to get that awful Rom (Destroyer) Manager off of my TF101G and have got Rogue on via PERI and now I'm trying to flash the stock ASUS ICS Rom but can't delete the Dalvik Cache because I'm unable to mount /data
Code:
- - Wiping all user data - -
Formatting /data...
Formatting /cache...
Formatting /sd-ext...
Formatting /sdcard/.android_secure
Cache wipe complete.
Formatting /cache...
Cache wipe complete.
Wiping dalvik-cache...
Error mounting /data!
I'm assuming that /data is stuck on read only?
Manually fixing permissions and then mounting /data also shows the same error.
HELP :crying:

I have the same problem. I know what lead me to it.
Its an Asus SL101
I have cyanogenmod correctly installed. In order to install a megatron rom I downloaded their app called megatron apps. Trying to download a rom from them I got validation error at end of download and I make the stupidity of change the download dir from /mnt/sdcard to /sdcard and then when I restart again it doesn´t load and CWM recovery give me the same errors (unable to mount /data or unable to mount /sdcard when cleaning cache or trying to restore a backup ).
The only thing I have been able to do its to install Rogue XM Recovery 1.5.0 instead of CWM 6.x ) but the problem to apply an update or restore a backup persists.
Any idea ?

Aaargh.
After a year and a half of heavy CWM and TWRP usage, this has suddenly happened to me too, possibly after flashing the updated TWRP blob from Goo Manager (although that's conjecture at best). My ROM (RaymanFX' CM10 v6) is fine in everyday use - no problems whatsoever, but now I want to update, and my recovery won't let me.
In the hope that something simply went wrong during recovery blob flash, I successfully deleted TWRP and flashed a different recovery (latest CWM) from ROM Manager, but the new recovery can't mount anything either - neither sd card, data, or cache. The error messages are more or less identical to TWRP's errors. My system MAY be readable, but I can't backup or restore or flash anything anyway, so I don't dare format it.
I don't have a Windows PC, so I haven't tried Easy Flasher. I could try it on my work computer if there's no way around it and if neither OSX or Ubuntu can help.
Any suggestions?

Hey mate ....
Sounds like you got yourself into a pickle .......
Give this a try .... Boot into recovery and ........
Code:
adb shell
killall -19 recovery
make_ext4fs /dev/block/mmcblk0p8
This should format /data, You will need to use the hardware button to force reboot......
reboot back into recovery and see if /data can be mounted now ......
Thx Josh

Thanks for the quick reply do you think this will fix cache mount and dalvik mount problems as the system can wipe date but not dalvik and cache.

Fixed

After much formats it appears to be that twrp was corrupt as after using a fresh recovery blob every thing seems to be in place and cache and dalviki can be mounted.
The only quirk is that no matter how I try to instal Zombie after the message to restart and enjoy it just hangs on the droid animation for more than an hour, so for the time being I went back to crombi-kk until someone knocks some ideas into me.
Thanks

Error trying to wipe Internal Storage (TWRP)

Hi, I tried to do a full wipe from TWRP, but I was unable to wipe Interal Storage, next message appeared:
E:mount -o bind '/data/media/0' '/sdcard' process ended with ERROR=255
Anyways, the message of succesfull wipe appeared (and internal storage was in fact wiped). I don't know if I should worry (everything works fine after installing CM.12.1 nightly 08/06). The previous firmware installed was OxygenOs (I had a remote session thinking they would accept a RMA but they instead installed Oxygen with the latest drivers ). Every time I try to wipe that partition again I get the same message (but it gets wiped).
Thanks for your help and sorry for my english!

hey and welcome ,
you should always install the newest Twrp. Just download it via playstore
an other method. Download multirom and install twrp from there.
For the next time. Wipe partitions. Try to repair theme and flash it back to ext4.
Now everything should be clean.
If your system runs without any problemes or issues its just a cosmetic issue not more.
regards

Are you using latest 2.8.6.0/2.8.6.1?

I faced this error once on twrp 2.8.6.1 a week ago. I wanted to restore my nandroid and the error repeatedly happened while restoring data-partition. I then booted the system and deleted some files from internal storage (which was about half full at the time the error occurred). Afterwards I rebooted to twrp and could successfully restore my complete nandroid. It's a bit shocking if you face this error when restoring a nandroid, because the restore process wipes the data partition first and then begins the restore.

That tip worked for me (i9192), I just install the last TWRP (I think this is not needed) and wipe /Data with ext4, wipe again to F2FS and restore, thank you.

HELP failed to unmount cache (device or resource busy)

at first im just failing at wiping cache.
now i cant even restore my TWRP backup.
it is saying "Failed to unmount '/cache' (Device or resource busy)
now my phone got no OS :crying::crying::crying:

I was facing the same problem.recovery twrp>wipe>advance wipe and then select system>repare or change size>change file system>select FAT
after doing it try to restore your backup and if you get error the only way flash your phone to the last build number(avalaible for your phone) and then install twrp recovery(last version).
restoring backup should be work with this method.

you can try this method
Mount>select partitions to mount : cache
select cache and after doing it go for restoring.

No need to restore /cache partition, exclude it The partition is used by TWRP that's why you can't unmount it.

I still have the same problem persisted. Can't wipe cache with this TWRP recovery. It says can't mount/unmont cache device or resource busy. Restore of the backup was impossible as well. Even when cache was excluded. Changing file types and repairing it also didn' work. In Mount cache is ticked permanently and it can't be unticked.
