I am having issues with doing anything with my sdard in TWRP. I am trying to do a wipe on the sd card and it fails. This is the error I get.
Using rm -rf on '/dev/block/mmcblk1p1'
E:tw_format_rmfr: unable to locate volume for device "/dev/block/mmcblk1
* Verifying filesystems...
* Verifying partition sizes...
I always come across errors when doing a factory reset too. Any help would be much appreciated.
Edit: I forgot to include this also affects my ability to wipe dalvik. Recover is always saying that sd ext is busy and can not be mounted

Typically, when the device busy message propagates to the Linux console, this means some process is locking files in that partition, or a command prompt is open in a directory that lies within that partition. Also, do you have sdcard2 ext_sd mounted as read only or read/write?

I get the same error when I'm trying to wipe the internal SD card, but I have no problems wiping other stuff (cache, factory reset, etc.). I tried the "fix permissions" option in twrp but that didn't help either. I also have no problems mounting my internal SD card to the PC. I would like to wipe my internal SD card but I'm not sure if its a good idea to format it while its mounted to the computer...and just selecting all the folders and hitting delete while its mounted to the computer doesn't sound like a good idea either. Any suggestions?

SD is most likely corrupt, mount to PC via twrp and format to fat32

I started up my Gtab today (running ICS 4.0.x), and it keeps popping up stating "Encryption unsuccessful
Encryption was interrupted and can't complete. As a result the data on your tablet is no longer accessible.
To resume using your tablet, you must perform a factory reset. When you setup your tablet after the reset, you'll have an opportunity to restore any data that was backed up to your Google Account."
WTF?
I tried booting into recovery mode, but it hangs after stating "Recovery key detected, Booting recovery kernel image"
That's all it does....
Any suggestions on how to correct this?
Thanks ahead of time...

1. As the message says you'll most probably have to do a "wipe data/factory reset" in CWM. Run the command in this post.
2. Which version of CWM do you have?
Im not certain what version CWM is but it was the most up to date at the time. I cant access CWM as it sits now.
Should I try to use NVflash to rerun the Full_Stock_NVFlash_CWM_5504_Touch-1, just as I did before I installed ICS?...then reinstall the rom?
I can not access CWM...it locks up after stating "booting recovery kernel image"

The usual reason for that error message on ICS is a corrupted /data partition. To fix it you'll have to do either a "wipe data/factory reset" or a repartition the internal SD card in CWM.
GunRunner said:

The most common reason for that is
a) using the wrong version of CWM for the bootloader installed on the system--ie. using a recovery containing a 1.2 kernel on a 1.1 bootloader or vice-versa.
OR
b) a corrupted recovery partition.
To fix both on ICS--esp. if you've used the nvflash package in the TeamDRH ICS OP--try reloading only CWM-5.5.0.4Beta15 using nvflash.
Can you tell me what you were doing before all this happened? I can understand the /data partition becoming corrupt, or, the recovery kernel being the wrong one (or the partition being bad), but, I can't figure out how both can happen at the same time without something explicitly being done to cause it.
Not sure if it helps but I am also getting this error, I will update as I attempt to troubleshoot.
ROM: G_Harmony_ICSv1.5(120)(SuperCharged) (4.0.4)
CWM: 2.5.1.1-bekit-0.8
I got both errors but the second was solved by unplugging my computers USB cable from the g-tab.
(I can not access CWM...it locks up after stating "booting recovery kernel image") SOLVED
Steps:
1. From the settings picked factory reset loose all data and SD card data.
2. Reboot to recovery (CWM).
3. Formatted the internal SD card and ExSD card using CWM.
4. Mounted SD card on computer using USB cable connected to the G-Tab.
5. Let windows format the SD card. (Was this bad?)
6. Loaded ROM.zip file over to SD card from computer.
7. wipe data/factory reset.
8. wipe cache partition.
9. install zip from SD card -> coose zip from sdcard -> G_Harmony_ICSv1.5(120)(SuperCharged).zip
10. Install.
11. Reboot.
12. Error screen "Encryption unsuccessful Encryption was interrupted and can't complete. As a result the data on your tablet is no longer accessible...." "Press this button to do a factory reset"
13. Press the button to the same results.

UPDATE 1:
When I did a rewipe i found that when i did the data wipe is said:
-- Wiping data...
Formatting DATA...
E:Can't mount /dev/block/mmcblk3p2
(No such file or directory)
Error mounting /data/!
Skipping format...
Formatting CACHE:...
Formatting SDEXT:...

Could it be that when I used my computer to format the SD card I did it wrong?
UPDATE 2:
I was browsing around the CWM options and I found:
advanced -> Partition SD Card
Click to expand...
Click to collapse
So I did that and then a data wipe again, and this time it said:
-- Wiping data...
Formatting DATA...
<<NOTE THE LACK OF ERRORS>>
Formatting CACHE:...
Formatting SDEXT:...
No app2sd partition found. Skipping format of /sd-ext.
Formatting SDCARD:/android_secure...
Data wipe complete.

I am hoping things should work now, I picked 2GB with a 0MB swap.
UPDATE 3:
Ok... should have figured that deleted my SD card files including my ROM "G_Harmony_ICSv1.5(120)(SuperCharged).zip" so I mounted it and copied it over again.
(I also did some mounting and unmounted and may have lost it there.)
UPDATE 4:
IT WORKS!! fixed, must have been because I formatted out the data partition, but CWM fixed this for me!
I hope this helps others with the same issue.
So I just got back from a trip to Vegas, went to upgrade MeanROM from 6.3 to 6.5, and then my SD card would not mount and my internal storage is not showing. I've tried numerous things to try and fix this, by mounting SD and formatting it (Fat32, quick format off), unplugging and plugging in the SD Card, using a different one. No matter what I do, using TWRP 2.1.8 doesn't recognize the SD card and gives a repeated
E: failed to mount /sdcard (invalid argument).
E: Unable to mount /sdcard
Any tips?
Old Twrp ya got....use Goomanager and update...see if that might fix it
Can't even get GooManager to put anything in system cause it defaults to SD card
?? Goomanager install the recovery to the boot partition...you did click menu/ Install OpenRecoveryScript ???
Try flashing CWM recovery and seeing if that helps? My first guess would be to format your internal but since you've already done that I would default to blaming TWRP

CMW is known to damage misc partitions
I just had a similar problem and the only lasting solution was to relock the bootloader, RUU, and reroot. It's easy and the newest RUU isn't difficult to reroot.
I was able to reformat in the internal SD a few times using a PC (before I ran the RUU that is) but it only lasted a reboot or two before re-corrupting. I wish I had just RUU'd from the beginning and not wasted effort with all the reformatting.
I have to much junk and empty folders on the phone. I tried format through CWM, format system, cache, data, emmc...everything is still there. I want to clean (as in new) my internal storage.
Does "factory reset" does that, or is it just for deleting any 'personal' data (pics, files) etc?
Thanks.
Wipe data/factory reset only wipes the data partition. What you want is to format the internal sdcard. Go to Settings | Storage and select "Format SD card."

Will I then be able to boot into recovery, or CWM will no longer be there and I'll have to use ODIN?
Also, am I losing ROOT when doing that?
No. No. No.
You can format the root files from CWM recovery. You said you tried that and it didn't do what you want.
Formating the internal sdcard will remove all your personal files from the phone, including pictures and any other files and directories you have created. If that's not what you want to do, then don't format the internal sdcard.
Formating the internal sdcard will not touch the system, kernel, data partition or any other root files. You will not lose root. So yes you will be able to boot into cwm recovery, or even into whatever system you have installed after formating the internal sdcard.

Common sense, make a backup (meaning copy and save your personal info to somewhere else first, you can delete them later if you really don't need them).
Also, adding to what creepy has said, be sure "SD card" is your internal storage, not external uSD.
I suggest you removing the external uSD card first, just in case.
The reason I said so because with CwMR and Task's AOKP, format SD card is formatting the external uSD card, while "format /emmc" will be do the internal one.
Just precaution.
Thank you both.
Yes, I already 'discovered' that formatting SD Card in CWM formats the external ...luckily I didn't have anything important there.
I still don't get it though. Looks like we are talking about two different things.
I have my internal storage fully backed up. I want to wipe it clean, as in a PC Format. Is there a way to do that, or can I simply remove empty folders in file explorer? Too much junk has been collected there in a year and a half of many custom roms and different apps that I tried and removed.

Refer to 2nd post. Your internal storage has 2 partitions. One is where all the system data is, and the other is where all the personal data is (where apps install to). If you do what's written in the 2nd post, it will completely wipe clean the personal partition.

Yes, formatting internal sd card (doesn't matter which partition) does not touch either of those.
After some 2+ years of constantly changing ROMs, I've noticed that my i9100 shows more often than not the message of "your storage is getting full" or whatever it says. It does not work by clearing apps' data or even removing some of them because it ends up showing the warning soon. Also, factory reset has proved not to do much, since it just does a data wipe.
So I have decided to proceed with a format by entering Recovery > Mounts & storage > Format sdcard.
I just want to check first wether I will be able, after the format has finished, to flash CyanogenMod back from the same recovery (having placed it in the external SD card, which I understand is not formatted together with the internal storage) and have it working all ok, or the format will disable me from doing something else.
So my questions are:
That 'format sdcard' option in the Recovery means the internal storage, right?
The external SD card (the actual physical one) is not affected by the format, right?
Will I be able to flash CyanogenMod back again from the same Recovery after the format?
In case yes, any reboot in between the format and the flashing would brick my phone?
Help is much appreciated! :laugh:

well as i had flashed a lot of Roms too, maybe i can help you...i'll try!
after formatting sdcard, u wont lose ROM. u will just format your sdcard(12 gb i think).
1) i think the "format sdcard" option is supposed to mean the internal storage. but in some roms that i flashed, sometimes the sdcard mean the external sdcard and EMMC means the internal sdcard...so first take a look. go to install zip and select install from internal sdcard or external sdcard and look up in the screen, if it shows that u are in /sdcard or in /emmc, so u can know what sdcard are u really going to format
2) if u select to format the internal sdcard, it will only format the internal sdcard. nothing else.
3)well, as i said in the beginning, you won't lose rom in the format...u just formated sdcard, the rom and its stuff are still there, in the device storage(not sdcard or external sdcard, but in a card that is only for system/phone stuff(its like the phone has 2 cards. one u can use and send stuff(12gb) and the other one is for system files(2gb))
4) i think it would not brick it, since u just formated the sdcard, the rom is still on your phone but in the device storage, like i said above.
the ROM files arent stored in internal sdcard or external sdcard(those u can send files by usb), they are stored in the storage of the device that is only for system files. so if u do a format it wont affect Rom or Recovery.
hope it helped a little...cheers
Short notice from my side: I doubt formatting your sdcard will help to solve your original problem (low memory). This message appears if the /data space (those 2GB where all the system settings and application data are stored) is almost used completely. The easiest way to clean up this data is a system reset (which will make you loose all your data) or you need to look whether there are applications occupying much data there and remove these apps / tell them to store their data on /sdcard (if this is possible) or to selectively remove some log files / temp data. But in this you should be very careful, because removing the wrong data might cause strange system behaviour.

I think that is not quite the problem I am faceing now. I explain myself: when I get that "storage almost full" message, if I check on Settings > Storage, the Internal Storage section (1,97 GB in total) shows an availability of only 205 MB and the bar is half full (see attached). First incoherence. I try to update any small app such as, for example, Bitcoin Wallet (1.3 MB) and it says it can't be updated because there is not enough space. Incoherent with the bar shown. Also, if I navigate to /data, it shows there is an amount of 2.31 GB inside that directory (incoherent with the amount shown by the Storage Manager. Other data folders, such as the one in /sdcard/data or the one in /data/data, are always smaller (3 MB and 425 MB respectively, also don't match any of the figures shown by the Storage Manager).
Some ROM installs ago, I remember I was able to install around 190 apps and no problem at all, and now I'm 160 and have to keep removing apps when I want to install more.
That's why I think my problem is not related to data, or fixed by a data wipe or factory reset. I understand there are too many files inside that are just lost from ROM to ROM, and not even the system know where do they belong to. It is running everything but fluent. I don't even remember what Project Butter is :silly:

Thanks for your help, dude! Much appreciated.
Anyway, I feel that, if formatting sdcard does not wipe everything, maybe then what I need is to go Recovery > Mounts and storage > format /system, format /data, etc. All of them except for the actual physical sdcard (wether it is /emmc or /sdcard) and the directory in which the recovery "lives".
So I have new questions now:
If I formatted /system, would the phone be bricked or the Recovery would still allow me to install a CM ROM stored in the sd card?
Is there any of the directories shown in Recovery > Mounts and Storage that represents the actual Recovery partition/space?
There's no recovery partition you can format.
You can format system, preload, and data partition.
But flash a ROM right after.
There are flashable scripts (ROM wipe or ROM nuke) you can use. It does all the formats and wipes, and even back up some of your folders.

It's a known bug, that Android's performance is decreasing very much as soon as there is less than 10% free on /data. Additionally I wouldn't trust the graphics you see, because especially if you have man small files, the space occupied on "disk" is much higher than the file size. If they are only adding the file size of the files stored there this will be misleading. As far as I know the block size is 4kb, so each file takes at least 4kb of the memory. You can try to move some apps to /sdcard, but this works only to an external one, so you can free some space. Otherwise have a look on /data/system/dropbox or /data/system/usagestats if you can find some files which can be removed.

well, as Sergeileduc said, u can't format Recovery. so answering your questions:
1) yes, you would still be able to flash any other Rom, since formatting /system does not affect recovery. Wiping this partition will remove Android from the device without rendering it unbootable, and you will still be able to put the phone into recovery or bootloader mode to install a new ROM.
2) i dont think so...u can't format recovery...
hope it helped you...cheers!

Just to add my own experience.....
Some months ago, my phone was suffering from poor performance (I was running CM10.1 at the time)
I decided to do a full format to totally "pristine" wipe my phone and start fresh. I copied a fresh version of the rom and gapps to my removable micro SD card and rebooted into CWM. I formatted cache, dalvic, preload, emmc and sd.....then just to be certain, I factory reset too.....
After that and while still in CWM, I flashed the rom and gapps and rebooted without issue......I believe this is what you want to do, so to answer your question. ...yes it is safe and possible to do this.....my phone is proof of that.....

Okay, so my phone wasn't sending messages all of a sudden. I have a P769 on jelly bean rooted. I restarted it and it got stuck in a bootloop over and over again after countless battery removals. I used CWM and tried to restore my backup of JB rooted, and all I got was a bunch of force closes. So I restored to my 10G rooted on ICS. All of my Google apps were gone and I went to take a picture and it said my internal memory was full and wouldn't read my SD card. I did factory resets and nothing works. I'm not sure what else to try.. any help would be appreciated!
Edit: I finally got JB to load and it would scan my SD card, then reboot itself while it was still up and running? I could see my backlights on my buttons flashing. So I took out my SD card, same thing. I wiped the cache and reformatted my SD card and now i'm getting an error message saying that my UIDs are inconsistent and it won't let me do a thing on the phone. My phone was fine 12 hours ago.. I haven't downloaded a thing or accessed anything at all.

How did you 'reformatted sdcard' ? Are you talking about internal memory(built in) or external memory (microsd)?
If you have some fresh backup system like 20x STOCK or whatever. (you can download it from XDA)
After this actions it will totally format your phone. You will no longer have system, apps, files that were on internal memory. It's kind of format C: on computer! So make sure you have backup on your external sdcard (microsd) and make sure to don't format your external sdcard.
I did it few times when I was messing around with custom ROMs so it's safe. I'm owner of P760 but don't think so if it will cause some problems.
1.Then you can go into CWM and mounts and storage and format following:
/cache
/data
/system
/sdcard - it is INTERNAL MEMORY (built in)
2.and then Advanced -> wipe dalvik cache
3. backup and restore -> restore from external sdcard -> choose your backup

I've wiped the data like the previous answer, and I also tried this.. I went into CWM and formatted all of this and wiped the dalvik cache, then tried to restore from external sdcard, which I tried my JB and ICS and neither worked. Right now I am on my JB and it just gets stuck at the T-Mobile 4G logo.
EDIT: I tried formatting everything and restoring from my external sdcard and my phone won't recognize my sdcard anymore. It says there are no files on it, but I try it on another phone and I can see the files.
I've had something along these lines before on my Huawei Honor. I never did work out what was wrong. I asked on xda and it was suggested that the partitions on the phone had resized/gone corrupt.
I'm not saying this is what has happened in your case. The sudden force closes and then no boot is what my Honor did.
Can you get software update mode to come on? Switch off, hold volume up and plug in usb from pc.

Yes I had the same problem when I upgraded from ics to jb. Never figured out what happened but I copied all my files to the computer then I formatted my external sd. After the format I just copied all the stuff back on the card. Also cwm doesn't work for the second partition. Good luck.
