Root Need a few files to be pulled!

Hiya everyone, It's been a while since I've been to this root section! How's everyone been? :) Seems like everyone's been busy!

Anywho I ran into a hard bricked LG volt a few days ago! No Screen, nothing, only "Qualcomm HS-USB QDLoader 9008" in device manager

I rummaged through loads and loads of forums and youtube videos until I came across something! If someone could possibly send me a few files from their device I would greatly appreciate it!

Requirements:

Any ROM that supports exFAT partitioned sdcards (CM12.1 Confirmed To Support exFAT sdcards)
It needs to be rooted
It needs to be factory reset (Through TWRP or CWM or whatever you use, stock works fine too)
The SD Card NEEDS to be formatted to exfat or else the command will not copy all of the file! Make a backup on windows or somewhere else.
It needs to be exfat because FAT has a size limit (Not sure which roms are compatable with exFAT partitioned SD cards)

You can pull the files by booting up and enabling USB Debugging and typing this line of code into a command prompt with adb support on windows


Code: 
adb shell
su
dd if=/dev/block/mmcblk0 of=[your EXTERNAL SD CARD LOCATION]/backup.img bs=512 count=30535646

It needs to go on your EXTERNAL sd because the file is 16 GB in size and may take a while. You'll need a 32 GB SD card minimum I believe

If someone could please take the time to do this and upload it so I can recover from this! I still use the Volt and would like to keep it as a backup in case the newer one breaks or something happens! Thanks in advance!

I can grab this for you later tonight, you'll get mostly stock (some sprint garbage removed) but everything needed for activation will be there. TWRP, rooted, zv5 rom & radio, zv6 upgrade downloaded but won't be able to install so I wouldn't recommend trying that without flashing a real stock rom. It will have some xposed residue in /system but shouldn't be an issue.

If you want to keep that rom just turn off notifications for play services in apps, then it won't bug about the update.

I don't think you understand, correct me if I'm wrong! I cannot flash a ROM, my device is completely dead. I have no recovery, no fastboot, no download mode, nothing. It's confirmed a hard brick! I need "these" files in specific! I believe these files are the qualcomm files I need to get the device powered up into fastboot. I don't need anything else but these files. I don't need the radio or firmware or anything, I can easily grab these files from forums and backups that I have. I don't think stock will let you use a exFAT card, but I can confirm that CM12.1 Does support exFAT partitioned SD cards
 
Nope I got you man, you want a raw image of the internal emmc, I'll netcat it out and upload it for you. It should be a hair under 8gb so double check you're looking at the instructions for the right phone. I have the original volt not volt2.

Alright sweet, thanks a bunch! You're a potential life saver! I believe so, it says it's for qualcomm mobile devices! I found this

And yes, I do have the LG Volt LS770

Haven't forgot about you; upload is in progress. If I would have thought of it, I'd have thrown gzip in the commands... and you mean LS740 not 770... 770 is Stylo?

Alright, thanks a bunch! Though i might need some guidance with how to continue! I'm resetting my laptop and goimg to try the whole process over again and see if that helps! And yeah i do, that was an accident, i have the ls770 now so i was just a bit mindpulled. Lol

But yeah the device I'm tryimg to restore is ls740
 
Sent you a download link in the messaging here

If you get this to work, I might get brave enough to try partition resizing on the emmc - I'd love to kill off that huge cache partition and maybe shrink /system a bit...

Actually wait, I messed something up resuming the file; it's got an odd number of bytes... I'm going to have to upload it again, sorry about that!
 
Okay file is back up and should be correct now. There is possibility of corruption in /data as this was taken from a live running system but I think you can just reformat it in the recovery if there's issues.
