A youtube video on this guide
Hello guys,
I rarely write guide and tutorials .so neglect my typos and gramatical mistakes
Today im gonna show you how to unpackLG H631 Kdz firmware so that you can stock deodexed,debloated rom.,
Lets get started
LINUX
Note: Python i required (v2.7)
Things Needed:
1) kdzextractor
2) Python/bash executable machine
Procedure:
1) First of all download your kdz firmware which you want to extract.
(folder path ex:~/Desktop/firmware)
2) Copy the downloaded Kdzextractor and place kdz firmware in the same folder.
ex:~/Desktop/firmware/Kdzextractor)
3) Open terminal and enter below commands.
Code:
chmod +x run.sh
./run.sh
4) Wait for the completion of the process and check for system folder on boot.img in your working directory
ex:~/Desktop/firmware/Kdzextractor/system
ex:~/Desktop/firmware/Kdzextractor/boot.img
5)8) Hell Yeah! you have successfully unpacked that kdz firmware
now you can make your own stock deodexed rom
Downloads For linux:-

Its just tweaked to work with boot.img's as mergerboot.py

@Innfinite4evr for testing this method and writing that bash script to automate the process and to write this guide!!!!!​
system.img it creates has no files.
Greetings.. I bought Xperia x F5121 ( 34.0.A.1.264) Android 6.0.1 (Prototype) online & found its prototype.Possible for me to root & flash custom rom.If theres a way,could anyone guide me .Thks in advance.I appreciate it.
My apologies admin.If i post wrong section pls delete it.
if the BOOTUNLOCK is allowed on your PROTOTYPE DEVICE then
short answer is : YES
dial *#*#7378423#*#* goto SERVICE INFO >> CONFIGURATIONS
HERE you will see alot of info, search for BOOTLOADER UNLOCK ALLOWED text and see what shows ,,, if NO then sorry! this device is locked by SONY and only they can unlock it
if BOOTLOADER UNLOCK ALLOWED has YES then MAGIC CAN BE DONE
IF YOU ARE NEW TO SONY WORLD then you must save XPERIA X DRM KEYS
since you are already on ANDROID 6 (YAY)
just enable USB DEBUGGING from DEVELOPER OPTIONS
and
download the UNIVERSAL (DIRTYCOW-BASED) TABACKUP SCRIPT ( DOWNLOAD FROM HERE ( REFERECE MASTER POST BY RAYMAN
uzip the script on desktop and RUN the .BAT file, it will ask permission on your mobile screen, ALLOW it and after few seconds, the SCRIPT will EXTRACT TA-xxx-xxxx-xxxx-date+timeStamp.IMG file (2mb in size) IN THE SAME FOLDER
you can run .bat mulitiple times! each time it will extact the same TA.img file with different file name , i ran it thrice
now you have your DRM KEYS FILE (SOME USERS SAYS ITS NOT NECESSARY BUT TRUST ME! IT IS! ) KEEP THIS TA.img file SAVED on cloud!
------------------------
UNLOCKING BOOTLOADER
SONY official handout unlocking keys for FREE at
https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader/
follow the steps! select your device model from list, provide them your email, they will send you one time link , to generate BOOT UNLOCK KEY AGAINS YOUR "IMEI" NUMBER ( dial *#06# on your F5121 to obtain IMEI number) (its even given on configuration page, where you checked the bootulock status )
- flashtool (www.flashtool.net) can ALSO unlock xperia Bootloader! (install flashtool and then install drivers also ( c:\flashtool\drivers)
- clicking BLU while device is CONNECTED IN FASTBOOT MODE ( it will prompt you) and giving SONY's generated KEY will UNLOCK your F5121's bootloader! device will JERK, ANDROID BOT WILL APPEAR and ALL PARTITIONS (accpt system) will be FORMATED and you will loose all your data, accounts, details , DRM KEYS ... (make sure you take backup of your photos/videos/music)

What is this for:
This tool converts xperia sin file and directly create flashable.zip for use to flash your android device with recovery.
Changelog:
- version 1. (missing selinux label generator)
- version 2. (implemented selinux label generator tool. Missing static busybox)
- version 3.
- version 4. some small corections, added missing update-binary
- version 5. some improvements, new sin unpack tool
How to use:
Extract sin2zip.rar archive & simple run CONVERT.bat & chose system.sin image , tool will produce flashable.zip
What you need to check or probably modify in generated flashable.zip:
1. busybox I have used is 32bit, it will work on 64bit too (not busybox.exe !!), I not recommend to change busybox, but before you go for busybox replace make sure it is STATIC busybox and have working (chcon and chown) with -h parameter!
2. check updater-script e.g. first 3 lines and last 2 lines!

Source code:
modified ext4_read tool is in attachment. Original ext4_read is here, many thanks to author! I have notified Igor, hope we see selabels listing integration in 7z without need for hackish ext4_read

This tool converts xperia sin file and directly create flashable.zip for using with recovery. 75 percent is done. 25 percent of the things is missing, selinux related things. I need help for implement selinux to the 7z to list selinux labels from ext4! Here is work in proogress

Maybe @SuperR. of SuperR's Kitchen fame HERE could give you some pointers on this. :fingers-crossed:
Maybe you could work together to integrate some of your great Sony specific tools into the Kitchen
That kitchen do not have anything related to our tool. I have done some progress in extracting selabels from ext4 by searcing with inode number \0/
Right now tool is able to extract selabels by inode number pointing
So you are on the drawing board again! Cool... :highfive:
About what you wrote in the j4nn's thread (1. to make fota unpack tool), count on me if you need help, ok!
If I'm not mistaken, I sent you a ota update_package file from my x performance some time ago, but if I am, here it goes again.
Cheers.

Thanks! I will look into ota package till after I finish our tool
Almost done! New version v2 is out! Made small tool to read ext4 image and print selabels to updater-script, it look like this:
if regular file or folder:
Code:
run_program("/tmp/busybox", "chcon", "u:object_r:location_exec:s0", "/system/bin/xtwifi-inet-agent");
if symlink:
Code:
run_program("/tmp/busybox", "chcon", "-h", "u:object_r:vendor_file:s0", "/system/bin/xxd");
Tool is curently 95 percent done, not realy ready for flashig produced flashable.zip , need to implement 5 percent of the things. You can try but plese do not try to flash with recovery it will not work corectly!
Version 3 done! Before you flash flashable.zip please check updater-script first 3 lines and last 2 lines! Do in mind our tool didn't include the rest of firmware like kernel, vendor...etc, tool only convert one sin file to flashable.zip, if you need the rest of firmware run CONVERT.bat and chose another sin file, do merges in zip by hand and do merges-modification in updater-script by hand too. Not recommended for newbies! I can't tell you if produced flashable.zip is working I'm not tried to flash flashable.zip, but I think it going work. Important thing is initial tool is done and somebody need to test. Let me know Enjoy!
Version 4 done. Enjoy!
@serajr here is some info https://forum.xda-developers.com/showpost.php?p=80599561&postcount=1330 , your file is the same format as j4nn
Version 5 done.
I am using LG V20 F800K (Korean version).
I tried to root my device without changing the BootLoader (I was tired of waiting and looking at the warning screen every time I booted up). It seems that LG changed Android 9 firmware file, I used this tool and found that the system files have been changed to system.img_XXXX instead of system_XXXX.bin, so I use Android 8 firmware file .
My question is after editing the system.img file, how do I add it to the DZ file and recreate the KDZ file?
After researching on GitHub, I found that this tool can recreate DZ and KDZ files. However, I do not know which environment it works in? Linux or Windows? I tried to use it on Windows and got the error:
Code:
[!] Warning: Data between headers and payload! (offsets 826 to 83768)
right from the extraction step of the KDZ file.
I tried to use it on my VPS, CentOS 7.5 and the same error happened (despite following the instructions to toggle the logic in dz.py at line 175.).
I saw a few people say that the tool works on Python 2. However, I tried it on both Python 2.7 (both Linux and Windows), Python 3.6 (CentOS 7.5) and Python 3.8 (Windows) but the same error still works. happened, so I think that the tool has a problem.
So I want to ask is:
Is there a way to root without changing the BootLoader?
How to add the system.img file to the DZ file, then recreate the KDZ file?
Thank you.
