Recover deleted files on UTouch / Nexus 5

@zlamalp said in Recover deleted files on UTouch / Nexus 5:
So, could it just work with /bin/nc and /bin/dd, ommiting all busybox ?
I would say: just try. The commands read from the phone, so I wouldn't assume it'll break anything.
The solution is for Android, so I guess it'll be easier (i.e. no need for busybox) for UT because that's a "real" linux. -

I probably misunderstood some netcat param (it doesn't have -e param in utouch). But I find out, that I did backed up most of the lost files, so I don't need to investigate this any more. But I guess, that with proper netcat syntax we can use linked solution for android on utouch.

I guess the syntax to be used on the phone would be
dd if=/dev/mmcblk0p28 | nc -l -p 5555It reads the entire partition and passes the output to netcat which then transfers it to the PC when the corresponding nc command is launched there.

I tried, but it resulted only in:
root@ubuntu-phablet:~# /bin/dd if=/dev/mmcblk0p28 | nc -l -p 5555 /bin/dd: writing to 'standard output': Broken pipe 129+0 records in 128+0 records out 65536 bytes (66 kB, 64 KiB) copied, 0.00488971 s, 13.4 MB/s -
Do you get that error immediately or after some time?
Have you done the matching commands on the computer side?The general syntax should be correct. I've tried a simple setup on my PC
In terminal 1
dd if=README.txt | nc -l -p 5555In terminal 2
nc localhost 5555And then I saw the contents of README.txt on the "client" side.

Have you done the matching commands on the computer side?It fails almost immediatelly, with random number of records (in/out). I did matching command on the computer side like this:
nc 127.0.0.1 5555 | pv -i 0.5 > mmcblk0p28.imgI didn't test it with a single file. I will try it and with localhost instead of IP too.
-
I now did a full test.
Terminal 1 (preparation on the PC and commands on the phone)
ingo@pc:~> adb forward tcp:5555 tcp:5555 ingo@pc:~> adb shell phablet@ubuntu-phablet:~$ sudo -i root@ubuntu-phablet:~$ /bin/dd if=/dev/mmcblk0p6 | nc -l -p 5555This then waits until I do something on the PC.
Terminal 2 (connecting to the phone over port 5555 and receiving the partition image)
ingo@pc:~> nc 127.0.0.1 5555 | pv -i 0.5 > mmcblk0p6.imgAnd when I saw
10485760 bytes (10 MB, 10 MiB) copied, 22.2077 s, 472 kB/sin terminal 1 I canceled the command in terminal 2 withctrl+c.I used mmcblk0p6 as an example because that is a 10MB partition for me. Enough for a test but not too much to wait for.

I tried exactly what you posted, but again with "broken pipe" error message. I tried even different (smaller) partitions with same result.

Maybe you can try some very simple test.
echo Test | nc -l -p 5555 -
Sadly doesn't work, but it exits with 0. I'm not sure but I guess its blocked on the way to the PC for some reason.
