hi guys
as you all know that some of the devices (i9300i) are hard bricked by flashing indian 4.4.4 so to unbrick we need a debrick.img which you guys can help us get by flashing this file https://copy.com/1ggUuyIqHUrF it will create a debrick.img into your sd card which you can upload and share
source http://forum.xda-developers.com/show....php?t=2439367
OR
Use this procedure to create the image
Enable USB Debugging.
Open cmd and navigate to your adb folder.
Run adb shell
Now type 'SU' to enable superuser, your may have to grant access to ADB from a popup screen of your phone's superuser app
next copy and paste the following code and change the phone model to your phone i.e. dd if=/dev/block/mmcblk0 of=/sdcard/debrickI710-16GB.img bs=1M count=128
dd if=/dev/block/mmcblk0 of=/sdcard/debrick[phonemodel-memorysize].img bs=1M count=128
6. Now type Exit on cmd and then use following the command to copy this image to your adb folder
adb pull /sdcard/debrick[phonemodel-memorysize].img
7. upload the image and share its link here.
[B]It will just take few minutes further you can compress the file (zip or rar) to reduce its size so that it can be upload easily.[/B]
Thanks in advance
:crying: i need it plz else my device will be useless

thank u soooo much bro i just successfully un brick my device tomorrow i will make a thread again thanks for ur time and million thanks to u :laugh:
Hi, I've used your CWM script but it doesn't have created the ZIP file with the debrick image.
I've searched it on all memories (also the system folder) but nothing. I've a GTI9301I ITV Firmware UANI1
I've tried also the adb shell and when i type adb pull /sdcard/debrick[phonemodel-memorysize].img it show me no devices (but it's enabled and the phone receive correctly commands)

It doesn't matter because we can't unlock
I've unlocked bootloader with old and official method so now I don't have any backup. Can I relock bootloader? Thank you for your excelent work

I got the same problem. I have nor backup of these files if i unlocked it in summer last year. No chance for people like us?
thanks dude, might give this a try, recently got my unlocked device returned from bootloop repair totally locked and going crazy with the stock rom
Thank you for this!
Regarding step 1, is this only for the COM port determination?
If i remember right the com port is also shown in the device manager (windows) when the phone is connected via usb.

This procedure treats about both lock and relock bootloader, so I thought that hopefully may work on 818p Eur version too.

It is about unlocking with the official BL unlock (LG-Website).
The only way is to dig into what xVANKO said.
Analyze the partitions before & after, modify them, pray and restore.
If someone would try it I would be happy because we haven't heard anything from him for a long time
and he also has the idea to relock/unlock the devices in exactly this way.
Hello blake_spector,
Thank's for your tutorial ! Look like amazing because i have the G4 since more than one year and get stuck on official ROM is so borring..
But i've a question, i bought my LG G4 in France (i'm french) and it's a H815 but how to see if it can be unlocked/relock ? On imeidata.net there is thoose informations :
Model : LGH815
Suffix: AFRAVK
Chip Type: EG
Network Code: FRA
Thank's a lot

Hello, ohhh yes ! It's a cool news ! After more than one year go to unlock my G4 ! No bootloop but bad battery life hope to get a rom like Samsung S7/Edge with a possibilty to change resolution like 1080P !
Which rom did u install ?
I've already dumped my partitions before unlocking with these commands:
dd if=/dev/block/mmcblk0 bs=8192 skip=585216 count=32768 of=/data/media/0/cust.img
dd if=/dev/block/mmcblk0 bs=8192 skip=16384 count=2048 of=/data/media/0/misc.img
dd if=/dev/block/mmcblk0 bs=8192 skip=40960 count=1024 of=/data/media/0/drm.img
dd if=/dev/block/mmcblk0 bs=8192 skip=43008 count=4096 of=/data/media/0/mpt.img
dd if=/dev/block/mmcblk0 bs=8192 skip=41984 count=1024 of=/data/media/0/sns.img
dd if=/dev/block/mmcblk0 bs=8192 skip=23808 count=256 of=/data/media/0/persistent.img
dd if=/dev/block/mmcblk0 bs=8192 skip=22528 count=192 of=/data/media/0/modemst1.img
dd if=/dev/block/mmcblk0 bs=8192 skip=22720 count=192 of=/data/media/0/modemst2.img
Does they are equivalent?
P.S. I have H815 ITALY LG G4

Maybe little off topic but you could already get down to 1080p even without root just adb commands
Thanks blake I was waiting for this moment since I bought my G4 tomorrow I'll do all the things and report back
Is send command compatible with USB 3.0?(I had some bluescreens during unlocks on my HTC phones) Can someone post a command for dumping data partition(one that stores all my things, apps etc)
Guys should I wait for nougat because of bootloader etc update or should i unlock now?
The main problem is that maybe they fix this gap...
Hi !
Thank you very much for this guide, I'm waiting for this since I upgraded to stock MM, which has caused me to lose root on my G4
However I couldn't do the step 3 because I don't find the partition images created during step 2.
Where are they supposed to be found ?
In the root of the internal memory, when I plug the phone in my computer or via en explorer app like Solid Explorer ?
My guess is the dd commands that create the partition files failed and the images were not created.
The first time I used the command to create drm.img, it seems that it takes forever (20~30mn+) so I'm forced to Ctrl + C.
When I execute the command again, I get the # prompt in like 2 seconds. The following dd commands last 2 seconds also.
But when I reboot the phone, I don't see any img files on my internal memory.
I tried to redo the Step 2 after rebooting, but the commands still lasts 2 seconds.
What did I miss ?
How long the dd commands are supposed to take ?
Is there some sort of requirements to succeed ?
I have of course a H815, 20i image flashed by OTA, I never messed with the bootloader, have 11 GB of free memory on Internal Memory.
My internal memory is also encrypted.
Thank you very much

Hello,
I have the same problem, i'm stuck on the 2nd step since 2 hours.
After LGUP restart to "COM4" i disconnect the phone and try to dump partitions but nothing special. Every command his finish in 1sec. The phone reboot when i'm at the "LEAVE" command and restart on a new install of my firmware ! Lost all my app (but already get a backup before)
I don't find any backup in the files manager, there is nothing.
For the moment i'm like you, at the same step... Hope to find a way to resolve the problem

No reason to wait. If you will like to relock, just get back on MM(not sure if LG will change the partitions on nougat so for now better to get back) and if you wish, upgrade to nougat again

I added a picture of 3rd step, the partition images should be in the root of the internal storage and accessible with the stock LG file manager.
I'm not sure what you might have missed, as I composed the guide from a continuous screengrab and video record of me doing the process.
The dd commands for drm, misc, persistent shouldn't take longer than 1sec (as they are only 8, 16 and 2 MB), the dd command for full_dump (~6 GB) might take a few minutes.
My internal memory is also encrypted.

That could be a problem, in my example the internal storage is/was not encrypted!
You could try to use LGUP and refurbish (!) to a fresh starting point (I used this KDZ https://forum.xda-developers.com/g4/general/kdz-firmware-v20j-united-kingdom-2016-t3518925) before doing the process.
OFC backup all your data first, as this will perform a complete reset of the device.
I ask to help to unbrick the phone. Prehistory. After an unsuccessful firmware phone has a brick. The phone is not detected by the computer (Unknown device). Reinstalling the drivers does not help, closing testpoints does not solve the problem. The only option is to create a bootable flash drive and flash it from under it. To do this, you need a complete dump of the phone. This is the request. Please make a complete dump of the phone with the extension * .img. Script for adb I attach Adb shell su Adb shell dd if = / dev / block / mmcblk0 of = / sdcard / image.img I am hope for your help

And how will you be able to "flash it under it"?
I wrote the same on the basis of a dump, create a bootable flash and from under it my own
