You need to connect the phone in usb debugging mode and run 'adb shell' to run the commands on the phone.

It Worked. Previously I forgot to Grant SU permission on the phone, upon doing it.

Anyone tried this on Xperia Ray phone?
Tried this in my Xperia Ray phone but got lust due to the partition is sorted in a different way compared to the Samsung phone.

I got the following results under blocks;

1|[email protected]:/dev/block $ ls
ls
loop0
loop1
loop2
loop3
loop4
loop5
loop6
loop7
mtdblock0
mtdblock1
mtdblock2
mtdblock3
ram0
ram1
ram2
ram3
ram4
ram5
ram6
ram7
vold
zram0

However, I donĀ“t know how to find out whats in the respective blocks so I can find my userdata and recover my lost files in the internal storage.

Any help would be appriciated or a link to thread on how to perform this on Xperia phones.

radio partition
My Galaxy Nexus suddenly lost all radio (WiFi works), but no network. Baseband version unknown. IMEI unknown etc.

My phone came with YAKJUXW firmware.

I tried installing stock YAKJU rom from Google - I flashed it using fastboot - to no use.

I rooted phone - and started poking around.

I see that radio partition ( /dev/block/mmblk0p9 ) may have issues - is this supposed to be ext partition in Galaxy Nexus?

e2fsck reports issues with this partition.

I need help to confirm if radio partition is corrupted. What would be mount point of this partition - is it /data/radio?

And if corrupted, how can I go about fixing the bad partition?

Thanks.

I don't know if radio has ext filesystem or not. You should rather ask that in Galaxy Nexus subforum. Here's some help:

I thought this was the galaxy nexus subforum - or did you mean I should start a new post?

I suspect my radio partition is not getting mounted at all - which might be why radio function is not working.

Anybody with Galaxy Nexus can report back if radio partition is mounted on boot and if so, where?

I mean that you start a new thread in the correct subforum.

Just flash a new radio and you'll be good.

Hi,
I made a raw copy of my i9250 memory, using this tutorial:
http://forum.xda-developers.com/show....php?t=1818321

I did one for mmcblk0p12.raw, and one for the whole thing mmcblk0.raw
The problem is that I don't know how to mount them in Ubuntu.
I've tried this but it still does not work: http://brainextender.blogspot.ro/200...harddrive.html
Code:
 [email protected]:~$ modprobe dm_mod
 [email protected]:~$ sudo losetup /dev/loop2 /mnt/hgfs/partitions-clone/mmcblk0.raw

You need to mount mmcblk0p12 on some existing directory on linux. You should know basic stuff about linux or you will mess things around.

mkdir example
mount -t ext4 -o loop mmcblk0p12.raw example
