Hi there
Although this is my first post, I am regular visitor of this forum since Defy's devs started porting CM and finaly is time to make a post (need a help ).
I have decided to flash Omars ROM but wanted to do nandroid backup first. My phone is encrypted due to exchange policy so I've backup my apps and wanted to do factory reset. For some reason I can't (neither through settings, stock recovery or CWM). When hit wipe data in CWM and confirm, all I get is:
wiping data
formatting /data
error mounting /data!
skipping format
formatting /cache
formatting /sd-ext
formatting /sdcard/.android_secure
error mounting /sdcard/.android_secure!
skipping format
data wipe complete...and everything is as before it.
I was thinking to flash sbf through RSD lite but wanted to ask if somebody had similar problem (I am not even sure if it is encryption related or not) which can be solved easily?
Thanks
//edit: because I couldn't figure out what was blocking factory reset, RSD did the job just right and now everything works great again (and custom rom is finally in)

I want to do a full wipe of all data when going from ROM to ROM installing to EMMC.
So far each time I install, some files are left over in one or other area.
I have yet to find a complete answer/quide on how to go about completely cleaning everything before installing a new ROM?
(Ideally the equivalent of formating and partitioning before installing Windows...)
At the moment I am cautious to try the WIPES and FACTORY RESET options in CWM as I have not found a solid answer as to what they do here.
(Is CWM the way to go here?)
Thanks for any help
There is utility like that for GTAB but didn't see one for NC

Let me see if I understand this correctly, you're saying you manually format each partition under CWR and are sketched about using the factory reset function? Ive both wiped and flashed between various emmc based roms as well as EXT4 based roms to the (EXT2?) based roms without a problem. Each time I use the correct CWR and manually format /system, /data, and /cache. If i'm understanding your question correctly then I hope this helps. It may not be the fix you're looking for but it works.

yeah - thanks, i think that is pretty much what i am after.
What is the difference between factory reset/wipe and formating the system/data partitions?
Is there anything on the boot partition that might get left over?
After my try to restore the imei (http://forum.xda-developers.com/showthread.php?t=1848811) I have a damaged /data partition. (Even if there's no coherence) I've done a factory reset and flashed the CM10 Nightly build 20/08 for SGS1 again (without flashing JVU again and than CM10).
I have installed Astro. If I want to install TitaniumBackup the error Not enough memory. (there is no other user app)
Something seems to be very wrong..
What do I have to do, experts?
Try formatting the Data partition again.
After I flash a rom, when i try boot into TWRP it asks for a password and refuses to mount any partitions unless i wipe data in there, and then wipe the other partitions in CWM... I have no idea what to do as this is pretty much stuffing everything up.
Edit: It's always the /data partition that need to be wiped...
I turned on device encryption in order to play with it (bad mistake). Performance is suckish, it prevents me from flashing anything stored on the internal filesystem (have to use USB dongle), battery life has gone down, etc.
I tried wiping the device by doing a factory reset both in recovery and through settings. Neither method touches the encrypted data partition. Re-flashing the ROM makes no difference. The encrypted partition is extremely resilient
Based on some research, the only known way to wipe the encryption is to revert to stock and use stock recovery to do a factory reset. This sounds insanely cumbersome if all I want to do is wipe a partition. Does anyone know of a better way?
If stock recovery can do a factory wipe without mounting the encrypted partition, it sounds like a feature to add to CWM or TWRP.
Device is ATT HTC One, rooted, S-OFF, Super CID, CWM recovery, Sentinel ROM 4.0.
Many thanks
You can try and flash an ruu? See if that helps and if it doesnt try the stock recovery thing. Never heard of it though.
Sent from my HTC One X using xda app-developers app
So, the wipe of TWRP didn't removed the encryption like it say this when you will wipe?
Strange
However, flash the stock recovery and do a factory reset like you said, and see if it work..
you can do it via TWRP just make sure the rm -rf mode is disabled in settings... Or maybe in fastboot... Just type
Code:
fastboot erase userdata
Or another perhaps is ask someone to create a nand dump of their user data partition and use "dd" to write it on your own.
Problem Solved!
Eureka!!!!
I was playing with CWM and figured it out. In the "mounts and storage" tab, if you select "format /data" it fails with an error that it can't mount the volume.
If you select "format /data and /data/media" it works like a charm. For some reason, it performs the format operation on the raw partition while the prior option tried to mount it first.
Back in business
Thanks RootShot ["format /data ¨in advanced wipe first¨ and format/data ¨& write yes in second¨ " ] did the trick and saved my phone back to work ...
Hello everyone I have a problem with my Galaxy Tab P1000L.
the problem is quite rare for me apparently not delete anything
from the internal memory.
installed several times the rooms froyo 2.2, 2.3 ginger, even after installing the room my files, photos, music, videos are still there.
the system is unstable in any room each app crash.
when I can open the settings and give reformatted USB storage says successfully formatting but when I look at the files are still there, as if I try to delete from the pc delete but not works the files are still there.
the problem could be some encrypted file o partition? , is there any way to make a super wipe or something similar?
from the Recovery -
wipe data - factory reset.
and says
wiping data formating /data
Error mounting /data!
skipping format ...
formating /cache...
formating /dbdata...
formating /sdcard /android_secure ...
formating /sdcard /android...
wiped all user data
but all data remain the same in the same place
sorry for my English, it is very bad. I speak Spanish
thanks and I hope you can help me miss my tab greetings to all
