[Q] Using dd for backup and restore in Qualcomm disk mode

[awaaas]

Hi there,
I'm using a carrier phone right now, specifically, Smartfren Andromax-U LE. It's packing MSM8625Q (Quad-core Cortex-A5 1.2Ghz), 1GB RAM, 4GB Internal, 8MP camera, 4.5" IPS LCD (540x960, 240 dpi)

Here's what interesting to me, when I searching button combinations to bring me to recovery mode, I found a mode that is supposed to be qualcomm disk mode (Windows suddenly told me to format it, meh), and then I tried to plug it in ubuntu, and there's some disk showing up (including android root, FOTA partition, and many more).

So, I was thinking, can I backup the entire internal memory (all 4GB of it), and then restore it back (in case something's go wrong) with dd command?

(This question is moved from here)

I would usually say this is a good (and better/easier in some ways) way to do a backup/restore but if its reading files from that partition/drive while its in its fastboot/recovery, it might mess things up. Its probably safer to mount the partitions and tar/zip them up unless your sure its reading the recovery/fastboot stuff into a ramdisk before running it.

It is not in fastboot mode, fastboot won't detect the phone. It's similar as nokia lumia series. Maybe if I backup the partitions one by one, it will give the result that I want, but not the simplicity

Actually, my friend did this, and his phone come back to life, but his IMEI is same as mine (can later changed with another software called DFS -I think- )

Here's what you gonna do if you want to get your phone's life back

Get a raw image from your friend's phone (must be the exact same phone)
Firstly, enter Qualcomm disk mode, and then plug it to PC, and type this in terminal (you must running linux to do this, not windows)

dd if=/dev/sdX of=~\raw.img

change X with your corresponding drive (it's usually sdb, or sdc)

and then restore it to your phone (unplug you friend's phone, and plug yours)

dd if=~\raw.img of=/dev/sdX

Good luck!

P.S.: after this, your phone (hopefully) will boot again, but the IMEI will be the same as you friend's

how do you get into this disk mode ?

By holding Power button and both the volume buttons, and then connecting the phone to PC with USB cable
