/mnt/asec/ is used when an application uses encryption

Probably, you'll have to generate a valid pit file.

Hi! Sorry for this very noob question but I just want to ask how did you do this? I really really wanted to know what my device's memory block/partition is because I wanted to recover some files.. I have a sony xperia J phone with me btw.. Thanks!

There's no exact procedure. The best way is to check under /dev/block of there is any block device listed. You can use adb shell to list all mount points and see if something coherent comes out.

I'm sorry again for this second noob question but how do you check "under /dev/block".. or "adb shell" Is it by using the command prompt or cygwin terminal? really confused with all these stuffs. sorry :/ just new to this.

You need to have adb installed on the computer and then enable USB debugging on the phone, and connect it via USB to the computer. That's basic stuff you should learn first.

The other are basic unix commands.

Run adb shell from Windows Command Prompt and then you have some examples on the first post.

pictures partition?

Hi!

This guide really helped my to identify some partitions, but some questions came to my mind. I hope you can help me.

Do you have any idea where are the photos saved by default in the Galaxy S3 (i9300)?

I'm trying to recover my girlfriend's photos that I accidentally deleted

Thanks a lot!:victory:

They are in data partition, where the sdcard is.

Thanks a lot.

So I mount the partition and I'm able to see a lot of files but none of them are photos taken with the camera.

As soon as I noticed that the photos were gone I rooted the phone, installed CM10.1, then installed CM9, then I started to pull out the partitions,I know this may affect the data and some photos may not be recovered, but I was hoping to recover at least some of them.
--My mmcblkop12 partition (userdata) is about 11.5gb, is it possible that I did something wrong when pulling the .raw of the partition file out of the phone?

Should I pull out the raw file again from the phone?
Should I try another recovery software?

Thanks in advance

On Nexus devices the internal sdcard is just a folder inside userdata, so if you formatted userdata is probably that they got affected.

Yep, that's the guide I'm following, the problem is that I can't find a single photo taken with the camera .. just old images of apps installed or cache files

Hi,
I tried this command but get an error. "Permission denied"

I have SU & busybox installed. Running PSX custom rom.

How can I fix it.
