Hi Everyone,
For some reason, TWRP is not able to format /Data.
It keeps saying "failed to mount /data (Device or resource busy)".
This doesn't prevent me from updating the ROM to 4.4.2-21.
However, once updated it keeps on booting over-and-over.
Is there a way to - sort-of - a forced format of the internal flash.
Or at least the /data partition as it seems to be corrept.
Thanks - Will
Hi,
With twrp use the wipe menu for installing kk 4.4.2
Wipe cache-dalvik cache-data-system-internal storage (if you need a complete clean install), after install menu, flash the rom and the gapps, return to wipe menu, wipe cache and dalvik cache again.reboot.you`ll run on the new rom
(Ps : don't used mount sd and format menu).

Thanks for the (quick) response.
I'm coming from 4.4.2-19. However, on previous occasions I was able to upgrade without going through a clean install.
So I tried the same this time with 4.4.2-21. However, as it stands, this release tends to end up in an ever on-going boot sequence.
Even a clean install or going back to the previous version (4.4.2-19) doesn't work.
Compared to previous installs, the only difference I can see is an error stating that /data can not be wiped.
Any thoughts on this behavior?
Thanks - Will

Hi, which release of TWRP do you use ? in 2.6.3.0 and lower release, on wipe menu you have an advanced wipe menu, go on it select format and type data, this will format data partition

Tried formatting the data partition. It comes back with "failed" - no explanation.
Any other suggestion?

Ok, with all of the talk about making sure folks do a full wipe before installing ICS, I would like to get some clarification on all of the different wiping methods and which is the best way...
I know of these ways:
1. Via custom recovery - you can wipe data, system, cache, etc.. individually.
2. Via holding Power+VolumeDown until bootloader text appears,, then wait until menu appears and select the Wipe Data option (instead of the cold boot option).
3. Via AARD SuperWipe full script
And then of course, there is the "Reset to factory defaults" in the OS itself...
Which is the best to use? I would assume the AARD SuperWipe full would be the most thorough as it recreates the partitions and everything (instead of just formatting them).
FOr users that have the ability, would an NVFlash of the OS be "more thorough" than CWM method?
Opinions/Experiences?
Thanks!
Don't use super wipe script. A lot of people reported having problems of some ROMs not flashing correctly after using it. There is no reason to use the "full" version anyway. It formats the /media partition(your internal storage partition) which you don't want to nor need to format.
Wipe Data in your #2 does pretty much the same thing as "Reset to factory defaults". They both wipe /data and /cache but do not touch /system.
The most thorough way of wiping that I use is via CWM.
I do all of this within CWM if I want to ensure a clean install of a new ROM and it has never failed.
- wipe data/factory reset
- wipe cache partition
- advanced / Wipe Dalvik Cache
- Mounts and Storage / format /system
I am not sure how NVFlashing a ROM does a clean install? As far as I know, it just flashes whatever it's told to flash. It wouldn't even touch /data if you were just flashing a ROM with it.

I've tried ALL of the above methods - all with the exact same results, to be honest...
Even if I revert back to honeycomb (even after a full wipe), I STILL exhibit the reboot issues (it's not just me - look around). This was NOT happening before with the exact same version of Revolver. This tells me that there is still yet something else that was changed during the ICS updates. We know the bootloader was updated - i'm now testing ICS with the old bootloader.
Other than the bootloader, what else could have changed?? Unless they upgraded the firmware on a particular device during the ICS update (wifi chip, bluetooth chip, etc). Other than that, I just can't come up with an explanation as to why Honeycomb won't even run properly anymore!

If you use the --create flag, nvflash will format ALL the partitions and then flash them. If you use the --download flag, it will just overwrite the partitions you send it.
That being said, I agree at your wiping method is more than enough. Most times, I don't bother wiping, especially data.

I've been using 4EXT Touch Recovery to wipe/format before flashing certain roms. Is there a right way on how to wipe/format using 4EXT Touch?
This is how I do it (correct me if I'm wrong):
1. wipe date/factory reset
2. wipe cache
3. wipe cache + dalvik
4. wipe dalvik cache
5. wipe battery stats
6. format system
7. format data
8. format boot
9. format all partitions (except sdcard)
10. format sdcard
11. flash rom

If you are flashing an update of the same ROM do "wipe dalvik cache + cache" (in case the Developer has not clearly stated that the update requires full wipe)
If you are flashing a new ROM use "wipe all partition (except sdcard)" it will do all the wipes from the wipe menu, no need to repeat it
And wiping the sdcard every time you install a ROM clearly does not make any sense, you are deleting all you pictures, music and all other files that are not related to any ROM you are using

I didn't know that "format all partition (except sdcard)" is the same from 1 to 8. I'll try using it from now on every time I install new roms. Also, I thought that wiping my sdcard every time I install rom is to make that rom fully utilized/functional. And that is why I back up all my pictures, music, and all other files in my laptop. Anyhow, thank you for your simple but very relevant response.
There are some ROM specific files on the SDcard but a full wipe (all partitions except sdcard) clears them too

This is noted... Thank you for all the info's... Greatly appreciated! :highfive:
I am a little confused on the terminology. I have done some searching and I came across the same question: http://forum.xda-developers.com/showthread.php?t=2107425 but it didn't really explain what manual format/system means for TWRP...
For instance, to install Slim Bean 4.2 build 8, it suggests to do a full wipe and then manual format system before flashing the rom.
How would I do this in TWRP? I want to make sure that this is DIFFERENT from format /data right? It is also different from "just" wiping "system" through "Advanced wipe" in TWRP?
Thanks in advance guys!

If you want to flash a new rom you have to go into TWRP
Wipe: Cache + Dalvik Cache + System
Wipe System is the same like formatting system

Thanks! Appreciate it. I was just wondering if formatting system is more of an active process that's different from wipe (eg. writing in zeros).

no its same
wipe = format
You don't need to wipe anything for flashing a newer version of some ROMs such as nighties. A factory is usually recommended to wipe the cache, dalvik cache and userdata to return the ROM to stock. Then when you flash a new ROM it will overwrite your current one.
Format System during SLIM installation
Hi,
Formatting the System is not risk the whole data i have on my device? in the past (as far as i remember,) doing it, deleted all the information i had on the device completely so it was even impossible to recognize it on the PC even all the drivers were well installed.
Looking forward for your advice.

Reboot back to recovery and wipe data,system,cache and dalvik cache.
Then install your omni and flash 4.4.x gapps.
Hope it helps

@SHELDON COOPR This might work.
1. Install latest Android-Andi TWRP recovery.
2. Check the md5 of the ROM and Gapps and copy them to your tablet (if you have a microSD card put them on that instead and insert it into your tablet.
3. Boot into TWRP and make a backup.
4. Click Wipe > Advanced wipe. Select system, data, cache, dalvik. If the ROM and backup are on your external SD card then wipe internal SD also.)
5. Flash ROM.zip and gapps.zip and any other addons.
6. Click "Wipe Cache/Dalvik."
7. After the wipe is completed, click "Back" then "Reboot."
8. Once the ROM reboots to the setup screen, let it sit for 5 minutes and then reboot back into recovery.
9. Click Wipe > Advanced Wipe
10. Select Dalvik Cache and Cache.
11. Click "Home" at the top of the screen and then click Reboot > System.
12. The ROM will go into "Android is Upgrading. Optimizing Apps"
13. Go through setup like normal and enjoy the ROM.

Wow, that could be a problem. I found this article that might work. http://www.digitalreborn.com/fix-samsung-galaxy-unable-mount-efs/
One other thing that I thought of was to Odin back to stock, but that might not work if what I said above didn't. So I would recommend looking at the link above.

Ignore what I just said about re-flashing stock with Odin.
efs is a partition on the phone's internal memory that is used to store important information (like the IMEI - the unique serial number of the phone). It's not accessible to a normal user and shouldn't get corrupted under regular use.*
With all of that said, you're apparently having such a problem, but I'm pretty sure that simply rewriting the firmware isn't going to fix this - that partition isn't included in the stock firmware files.

Quoted from http://forums.androidcentral.com/samsung-galaxy-s3/377195-what-does-failed-mount-efs-mean.
One thing I make sure I always do is make a backup of EFS before I flash anything. (The latest @Android-Andi TWRP will do this)

HI everyone
is there any chance to restore efs to my tablet, which i accidentally deleted while installing new os.....

You may have installed the wrong rom like P3100 instead of P3110?
Happened to me with my P5113, instead of P5110 , I did P5100.
Was able to go into D/L mode and odin flash correct rom.

Hi! anyone know why I get this message every time I turn on the Tablet? that's what I do?
Depends what your situation is:
Custom rom and recovery?
Enter TWRP > Advanced > Fix permissions
Stock, no root?
Reflash Asus firmware
I did fix permissions but the same result. The massage said: UIDs on the system are inconsistent, you need to wipe your data partition or your device will be unstable. How could I do wipe data partition?
I have t700 cromi-xenogenesis 5.4-10.6.1.27.5 we codex with TWRP 2.8.5.0 installed.
Thanks
In TWRP go to Wipe and swipe the button.
Then reflash your rom.
It'll wipe apps and settings but not your personal data.
If that doesn't help, you'll have to format data in TWRP. That will wipe everything on internal, so backup first.

1. One could ignore the message (that what I did once for months without problems).
2 Install newest Titanium Backup, on start it has a routine that can fix that problem. Or go to Menue=>device=>manage Android ID.
I finally installed the ROM Cromie-kk without errors. the only problem I have is that the screen has lost sensitivity. I need to do much pressure on the screen to perform the action. After a few seconds, the action runs. It is a hardware, software ??? Thanks for all
