Probably you didn't move nc.exe (from netcat) to your bin folder of cygwyn

I did that, it's there with 42 KB...

HelpNeeded1 · Feb 21, 2015

last picture is you need something like this except you need to find the correct msm_sdcc.1 folder for your phone

ls -al /dev/block/platform/msm_sdcc.1/by-name

with a root editor (es file explorer) go to your data folder then dev then block then platform look in each folder to see which one has the by-name that folder will be your correct folder Mine is msm_sdcc.1

sry, but which lines do I then have to write? and how/where all do I use the folder msm_sdcc.1?
(attached two pics of my current status)....and REALLY thanks for your help!

Is there anyway to recover after a factory rest on stock 4.3 in gt-i9300?

Hi guys,

first and foremost thanks for this great thread for us (almost) hopeless! The data on my Nexus 4 became victim to a bootloader unlock for root. Now after discovering the thread I spent most of the sunday struggling to reproduce the steps in the instruction and FINALLY got a mmcblk0.raw with a healthy size of 14,68 GB, which I converted with VHDtool and renamed with a .vhd ending. I added it as a virtual HD in diskmgmt.msc. Now comes the problem:
It doesn't let me initialize the disk and/or create a simple volume. It's all grayed out. What's the matter?

Maybe try another way to view the raw file or try another computer.

nc fail!

Hi Guys,

Little update of my situation.
I found that the reason I was not getting any data transfer was the version of netcat (nc.exe)
I have remove the nc.exe that was linked in the original post.

The version I am using successfully is available through the Cygwin packages.
If you need to install this just run the Cygwin installer again, selecting the same settings you did originally with the exception of adding the nc package.
You can find this under the NET category - for some reason this did not come up on search for me, I had to manually find it.

This works wonderfully - I will report progress as I get further through the process.

Doof.

What version Android are you running?

Just rename the .raw to .vhd and it should work

---------- Post added at 02:46 PM ---------- Previous post was at 02:39 PM ----------

It was a lifesaver.

I might agree that sometimes there are a few more instructions that could be more helpful when one is panicking about the lost data, but if you try a bit what is given as instructions you can achieve the expected result.

I have retrieved 95% of my data (I had to install busybox) and all was good.

So I can safely say that my OnePlus can be re-used

Thank you very much Wartickler for this guide

Awesome work! What version Android was on the OPO? A couple posts mention newer versions of Android do secure wipes when a wipe is done. Trying to ascertain...

Hi All,

I must say that after being on this forum for the past 2 days, from finding everything rocket science...i have learnt tons! Thanks a lot.

I have managed to clear almost all issues reading through the forum, however i am stuck with extracting the raw image. I'm using HTC One M7 - International Version on Windows 7, 64 bit - using cygwin 32 bit version. When i enter nc 127.0.0.1 5555 | pv -i 0.5 > mmcblk0p37.raw the data transfer starts for maximum of 2 seconds with only 58 bytes copied. I have tried reinstalling net cat and cygwin to no help.
Any solutions for this?

Thansk in Advance!

do you have any errors on screen also did you verify your file path to see if it's correct

also you may try to run cygwin as administrator too (right click the shortcut on desktop and run as administrator

my block is mmcblk0p25

I verified by typing in a windows cmd window

adb shell
mount

then you will see your path as you see in picture /dev/block/platform/msm_sdcc.1/by-name/userdata /data I then know my by-name folder msm_sdcc.1

then type

ls -al /dev/block/platform/msm_sdcc.1/by-name to verify your partitions mine is userdata -> /dev/block/mmcblk0p25

then you know it should be a /dev/block/mmcblk0p25 mine is also 26 GB in size when done (about 2 hours time )

did you open up these pictures in this post? and use to verify with your screens

Thanks for the prompt response.
No there were no errors except LC_ALL, en language error on cygwin terminal on start. I verified the path using adb shell mount and got /dev/block/mmcblk0p37 /data ex4 rw as a result.

I am reinstalling cygwin one more time from scratch and will try to run as admin again.
Last night i tried to run the cygwin 64 bit and the timer went on with 0 b/s write speed and it was only in the morning after 8 hours i realized that it didn't even initiate copying. :'(

Didn't work running as admin. Just a note. I am installing cygwin in D:\ of my system and im altering the commands accordingly - "export PATH="/cygdrive/d/AB":$PATH" Hope thats not the issue?

if your reinstalling CYGWIN to D, you should be able to point the setup installer to that d:\ the you would not have to alternat any commands

also I have 64 bit system and I'm running 32 bit cygwin too, i always seem to have issues with the 64 bit version

Also make sure you have developer options and usb debugging checked in your phone settings

first cygwin cmd screen

adb forward tcp:5555 tcp:5555
adb shell
su (watch phone screen be ready to give SuperSu permission)
/system/xbin/busybox nc -l -p 5555 -e /system/bin/busybox dd if=/dev/block/mmcblk0p37

and leave that screen alone

start another command screen

you may want cd to a clean folder like I used note3 in my home folder

adb forward tcp:5555 tcp:5555
cd /note3
nc 127.0.0.1 5555 | pv -i 0.5 > mmcblk0p37.raw

Hi Carl,

Isnt the C in the command line for C:\Drive, because my ADB is also in D:?
Also, i tried ls -al /dev/block/platform/msm_sdcc.1/by-name: and the outcome was permission denied?

Thanks.

because you need ROOTED phone and also to enable usb debugging in setting of your phone

and watch your screen to give PC access and then watch phone screen when you type

adb shell
su you will get a prompt from superSU

all this with pictures in post I gave you

Hi,
Phone rooted check
USB Debugging check
busybox check
SU permissions granted
after reinstalling cygwin and copying nc, not its gone back to copying 0 bytes at the nc command!

Great guide OP. Any program for the recovery that keeps the filenames and maybe even the file structure?

Contacts.db

Great guide OP and thanks a lot for the useful information. Just wanted to point out that the nc.exe referenced in the OP does not work. As someone else pointed out in the thread, the nc.exe bundled with the latest cygwin does the job fine. Took me an entire day of mucking around to figure this out.

I have mmcblk0p25.raw and mmcblk0.raw extracted now (along with the VHD header added). Recuva does not seem to find the contacts.db file in the mmcblk0p25.raw partition. Anything I missing here please? Are there better programs to 'deep scan' for .db type files?

great guide!
i did unlock bootloader and overread that my device gets wiped

all i need is my whatsapp folder, im on a moto G 2014 and copied mmcblk0p38.raw but after scanning it, it will find only a bunch of about 50 files. (some .png's of screens of when my phone was booted last time, but i didnt took any screenshots)
shouldnt it find at least all files from the current installation?

for file recovery i used easy recovery, remembering this as a good recovery tool when i works as it support.

another NOOB question.

My son accidentally did a factory reset by touching buttons too fast during fast boot. I have been trying to recover his lost files. I have been learning a lot but still have some questions. I have ADB installed and get a valid response to the device command. Isn't there a way at this point to use ADB to pull an image of the phone without installing busybox? I would rather not install anything on the phone after the factory reset. If I try to install busybox through the playstore it wants me to log in as a user. Once I do that it will start downloading all the data for that user. Both of these actions will overwrite data.

Thanks for any help
