[Q] Can't wipe data / factory reset

[orson250]

Ok, I have been searching for my exact issue for the greater part of today trying to solve my issue and I haven't come across anything so far.
I am on running gingerbread 2.3.4 with the UnOriginal 1.4.6 minimalist edition rom.

Basically, whenever I reboot my phone, it reverts back to its state on Sept. 27. For instance If I send a text, upload some music from my computer to the phone, and take a picture, all of that data will be missing when I reboot. All of the texts I sent, pictures I took, numbers I've added, etc. are gone. I can't put files on my phone anymore because as soon as I take it out of USB storage mode, the files are gone.

Things I have tried:
1. A factory reset / wipe data from the phone's settings menu and from CWM
2. formatting /system, /data, and /cache in the "mounts and storage" menu in CWM
3. formatting the phone from my computer
4. flashing a stock rom and PIT file from Odin
5. flashing a rom from CWM

No matter what I do, it always boots up the same as always with the same boot animation, the same text convos, same address book, pictures, etc.

I can't mount anything in CWM's "mount and storage" menu. It just gives an error: "unable to write to ums lunfile"

Does anybody have any ideas? I'm completely stumped at this point.

I would get into CWM mount storage and delete everything and upload a rom and try to flash it so it has nothing to fall back on

Thanks for the quick reply. should I format /emmc? I formatted system, data, and cache and when I rebooted, it still booted up to it's sept. 27th state. Should I format system, data, cache, and emmc and then try to get into download mode for odin? Could it be a faulty internal SD?

Mount storage to your pc and delete everything (make a backup if you want). And just put one rom in there and see if the problem persists after flash

I mounted the phone to my computer via the in phone prompt instead of CWM and deleted everything off of the internal sd card. As soon as I disconnected the phone from usb storage mode, I used the file browser on the phone and all of the files were still there. Wiping and formatting everything and flashing a new rom in CWM yielded no results as well.

This is really strange behavior to me. Any other suggestions?

You're Making this waaaaaaay to complicated. Just flash another rom. Unless you used rom manager to get into recovery. In which case you didn't read enough. But if not yeah just flash a rom.

Alright so when I go into "mounts and storage" in CWM, I can mount/unmount everything except /sdcard and USB storage.

When I try to mount /sdcard it just says: "Error mounting /sdcard"

When I try to mount USB storage, it says: "E:Unable to write to ums lunfile (No such file or directory)"

What's up with that?

When it says mount USB storage it means external sd card. How do you have your sd card currently formatted? (fat32)?

Ok, well that explains why I can't mount USB storage as I don't have an external sd card, only the internal one.

I tried to reformat the internal sd card from my computer to fat32 (it was already fat32), but it didn't actually wipe anything. I'l try unchecking "quick format".

I tried wiping and flashing a few more roms, but still nothing changes.

Thanks for all the help so far guys, but I still can't figure out what's going on and why I can't seem to modify data on the sdcard long-term.

this problem has been solved? or not yet? cause this my problem too. Cant wipe data. The rom and data are still there.

Why did you necro a 2 year old thread? It would be better to post a new thread stating your issues and information.

I do not remember this issue ever being solved. This may be the only person that has posted with an issue like this, as far as I can remember, until you posted.

What are your symptoms exactly; What firmware is on the phone; What can you do with the phone; What have you tried? Give as much information about your phone as you can think of.

For instance, have you tried flashing the full stock distribution with Odin?

How do you perform this step? mounting the device on your pc. I've tried to do this via terminal on the device itself but it can't get to mount the partitions i need to wipe.
