[Q] Can't Factory data reset my phone. Help??

Hey everyone so idk what happened i was trying to run the kc1 kernal so i can have CWM and i can't reboot or factory data reset my phone.
This is what it says when i try to factory data reset my phone on Manual Mode:
--Wiping data...
Formating /data...
E:format_volume: rfs format failed on /dev/block/stl10
Formating /cache...
Data wipe complete.
Than when i try and reboot my phone it says:
E:failed to mount /data (invaled argument)
E:copy_logs_files_to_data :: can't mount /datareboot...
Than it just goes through a boot loop
Is this because i axcidently partition my micro sdcard and lost everything on my micro sdcard??
Is there anything that can help me? Links and other stuff would be very appreciated. Please help asap!!

Did you have a voodoo enabled kernel on there before? If so, you'll need to flash a ROM, then flash a voodoo enabled kernel for that rom, then go into recovery & disable voodoo. Sounds like you have a bunch of ext4 filesystems which the native ROM/OS can't handle.

Surely. Flash Raver's KJ6 ROM here:
http://forum.xda-developers.com/showthread.php?t=1353176
Then flash drhonk's KJ1 kernel (put it in the PDA section of ODIN):
http://forum.xda-developers.com/showthread.php?t=1194032
That will put you on the latest Gingerbread ROM with a kernel that has CWM, voodoo, and root.
If you want to flash back to KC1 after that, reboot the phone into recovery mode and (using the vol + & vol - to navigate up and down, power button to select):
- Scroll down & select the 'voodoo' menu
- Select 'disable lagfix'
- Select '/system lagfix off'
- Select '+++++ Go Back+++++'
- Select 'reboot system now'
Let the phone fully boot. It might take a few minutes while Linda converts the file systems from ext4 back to rfs. Once it's fully booted, you should be able to flash KC1. Just ensure the KC1 you have contains Froyo boot loaders else you'll end up in a boot loop or with the rainbow screen.

If you can get into download mode the instructions I gave you should work OK. Definitely let me know how it goes, though.

No, /data doesn't reside on the sdcard (that's mounted as /sdcard, different mounts). Check the Dev section for Chadster's KG4 leak. It has 4 files in it, one of which is the .pit file. I wonder if flashing that would help? Just put the .pit file in PIT, the CSC file in CSC, the Phone file in PHONE, and the other file in PDA.

Awesome bro, glad it's working. You should be able to flash drhonk's kg4 kernel with cwm/root/voodoo, upgrade to KJ6, or whatever you want to do now.

When i reboot my phone it wipe all that i saved

Hey guys, i didn't found my problem in other topics, so i opened a new .
So here is the deal, i have the Kisadworx ROM installed now in my Samsung galaxy 3 i5800, and already tried the Kyrillos and both of them have this same issue. When the phone shutdown for low battery, i put it to recharge and when i boot it, it wiped all i have saved. Apps, configs, widgets....just everything. i have no clue why...some one have faced this issue before?
Note: when i enter in recovery mode and try to wipe data/factory reset it shows a message:
E: can't mount /cache/recovery/log
E: can't open /cache/recovery/ log
E: can't mount /cache/recovery/last_log
E: can't open /cache/recovery/last_log
I don't know if this error is related but ok ....
Plz someone could help me?

I had this issue days ago, and it happened to me while I simply only turned off and on my phone.
This is probably caused by bad data and cache(?) partition or by bad (wrong) filesystem used. Try re-flashing STOCK rom eg. XXJPQ and over it custom rom of your choice. If the problem persists, try flashing custom kernel (g3mod) and convert file systems like this:
stl6 - ext4
stl7 - ext4
stl8 - ext2
I never had any issues with g3mod kernel's recovery with theese filesystems.
In gingerbread ROMs I had never issues with data or recovery.

Do you have an ext partition on your phone?
I got into similar problems with the scripts related to ext partition long ago
I too get the recovery error and it is not of any problem to us . This is solved by using g3mod kernel

hey guys, i followed as twinky444 said and it apparently worked. I reinstalled the stock ROM but a got the samsung bootloop, then a tried again and i made it, after, i installed the kyrillos 10.5 and it''s currently working, with no problems of data lost. I think it was some corrupted data problem. Thank you very much guys

If youre going from ROM that uses other filesystems than stock samsung's RFS filesystem such as ext2, ext4, so by flashing the stock ROM causes the bootloop WILL be there. (because the stock kernel doesn't support other filesystems than RFS) You need after flashing stock ROM pull the battery, reinsert it, reboot into recovery by pressing 3-keys combo and then "wipe data - factory reset" in recovery and then "wipe cache partition".
After this, the /data and /cache partition gets either mounted again or reformatted (not sure) with the rfs filesystem and the system will be able to boot.
BTW/little hint: You can see for couple of seconds after flashing the stock rom the phone boots into recovery, shows a couple of lines and there are 2 lines that are RED and say something like
DATA: blablabla... !
CACHE: blablabla... !
This process applies to the ROMs such as Purumod, Kyrillos and maybe others what have other filesystems used than the one used by the stock ROM (RFS).
Thats the description of the "bootloop" problem.
BTW... glad we could help and this has been fixed!

[Q] Error E:format_Volume: make_extf4fs failed on on dev/block/mmcblk1p2

Im having a trouble reflashing a ROM. During my efforts to fix my horrible battery life problem by doing Odin back to stock and reflashing DK ROM something else has gone wrong.
I go to to Recovery and I tried to wipe data and Reset to Factory
it says
Formatting / data......
Formatting / Cache....
Formatting / sd-ext....
E:format_Volume: make_extf4fs failed on on dev/block/mmcblk1p2
Formatting/sdcard/.android_secure....
Data wipe Complete.
It also says, sd-ext.img not found when I restored my Nandroid backup. Not sure whats going on here...
When it restarts, its still the same old rom with everything still there, just with user data wiped like my google login. How do I fix this? I have already Odin back to stock, rerooted and CWM and am still getting this issue. Could this be contributing to my terrible battery drain?

Nothing wrong, that's normal.
ROMs on phones that didn't have enough local space to install any real number of apps, etc (think Nexus One, or HTC Evo 4G) used to create a second partition on the SD card. This partition was formatted to ext4 and mounted in place of stuff like /system/apps or /data, etc..
Nandroid simply tries to format the partition if it's there, and obviously it isn't. I doubt anyone here has that partition. The sd-ext.img would be the image file nandroid would create if you did have the partition and you backed it up.

But the problem is I cant flash another ROM without doing the factory reset, and when I do factory reset I get that error and the new ROM isnt flashed.... I have never had this error before when I flashed DK originally, or on my last Blaze phone. I need to fix this issue so I can flash a different ROM, or next newest update to this ROM.

You've got some other problems then, because I get that error all the time and have for some time on all sorts of phones.
Once the /data partition is formatted, your wipe is complete. The /cache is good stuff too... once you see those two lines, you are all resetted.
If you nandroid restore, you're going back to what you had.

So why wont it factory reset then? Everytime I do factory reset in recovery, it shows all my files and stuff still on the phone. It never completely wipes my phone. I dont know what to do or what the problem is...
Is there a certain way everything is supposed to look in mounts and storage? Whats supposed to be mounted or unmounted? And what should be formatted?

Factory reset doesn't wipe your sd card. For that you have to format it from the settings menu.

Can you explain how to do that?

I beilive he means in CWM, under mounts and storage, format /sdcard
Sent from my SGH-T769

No, I meant in android. I'm sure a quick Google search would turn it up, but here goes: Settings -> Storage... you'll want to unmount first, then format.
SD card = removable card
USB Storage = internal storage
Just remember, this will destroy ALL your data on whichever you choose to format. Everything, your pictures, music, etc...

[Q] CWM cache wipe -> storage corruption?

So I was going to take a nandroid of my Nexus 5 in order to transfer to my RMA device. I have found that device swaps usually go over better using CWM for nandroid instead of TWRP. So I flashed the latest CWM from ROM Manager and booted into it.
I figured I would save space if I blanked the cache, so I initiated a cache wipe. The display become a broken-up Android picture, and the cache wipe did not complete in minutes. I long pressed power to boot into the OS and found that - uh oh - the entire sdcard folder was inaccessible. All app data appeared to be intact but no app could read or write the sd.
Did I just completely bork all my internal storage? Any possible rescue path?
EDIT: OK I flashed recovery over to TWRP and its file manager still shows all my files. So all is not lost. But something went wonky and the OS is confused now.
In TWRP when I try a cache wipe I get:
Updating partition details...
E:unable to mount '/cache'
E:unable to mount '/cache'
E:unable to mount '/cache'
Formatting Cache using make_ext4fs function.
And it sits there chugging the status bar. Been over a minute now.
Aha okay, it finished. Fingers crossed... Yeah OK it's fine now on another full boot.
Still a bit strange though. Normally on any other device I've owned, a cache wipe was a simple matter.

Its an issue on the nexus 5 for some reason, took 5-10 min on my phone before but i think it was fixed in the latest twrp.

Yes, on TWRP 2.6.3.4 it took 5-10 minutes but fixed it. It would seem that there is a simple cache wipe versus fully formatting the partition. If the first fails to work, it proceeds to the full format.

/data partition corrupted

Hi guys. To spare you the details and cut to the chase after rebooting the phone in ICS i got a message with "Unsuccessful decryption" and i needed to restore factory to continue. And i got into the CWM5 recovery and tried to wipe data/reset
All partitions were formated but /data:
E:format_volume make_extf4fs failed on /dev/block/stl13
Mounting works expect /data
So i can`t format /data and dalvik cache.
I tried to restore to stock GB with odin and all worked fine until the phone reboots and goes into stock recovery and tries to format data but gives error:
-- Wiping data...
Formatting /data...
E:format_volume: rfs format failed on /dev/stl13
and reboot to bootloader and stuck in bootloop.
I know this looks pretty much like /data partition corruption..
I asked if anyone can help me with this issue :/ I`ve read other forums that this can be fixed but i am afraid to use other phone`s tools not to end up bricking it dead.
I have added recovery report View attachment recovery.txt

I have been googling alot this past time and tried all sorts of binaries and zip trying to repartition slt13 but no luck.
For what i have learn i have one more chance of resurecting the partition with RIFF JTAG Box on low level...
Can anyone answer this question:
If all partitions are working fine exect stl13 (/data) is there any chance the NAND chip is dead/corrupted?!
I don`t alot of physical hardware of my device so is there a separate NAND chip for /data or it is a single chip for all partitions? (I.E: /system/ ; /data/ etc. )

Facing the same problem!!
