[TUTORIAL] How to extract BIN + FLS from KDZ

Guys, I've seen some people wanting to access BIN roms and/or FLS basebands included in KDZ official roms, and not knowing how to do it.
I've searched the forum, found out how to do it, and decided to make a tutorial for our phone.
Here it goes:
0. Have a "KDZ official rom" file to extract
1. Download attached LGExtract.7z and put the included LGExtract.exe file in the same folder as your kdz
2. Open a Command Prompt
3. Change directory to the folder where you have put the previous files (LGExtract.exe and KDZ file)
4. Run this: LGExtract -kdz V***_00.kdz (use your kdz's name, for example LGExtract -kdz V30A.kdz)
5. Manually extract the CAB file in the same dir (use 7-zip or WinRAR)
6. Run this: LGExtract -wdb V***.wdb LGP920.dll (for example LGExtract -wdb V30A.wdb LGP920.dll)
7. Now you have some files, a few numbered BINs and one FLS)
8. Change directory to BIN folder to manually merge the bin files
9. Run this: copy /b "LGP920_AP[*].bin" "LGP920_AP.bin"
Should output something like this: (THE NUMBER ORDER MUST BE ASCENDING)
LGP920_AP[0].bin
LGP920_AP[1].bin
LGP920_AP[2].bin
LGP920_AP[3].bin
LGP920_AP[4].bin
LGP920_AP[5].bin
1 file(s) copied
10. Now you have your BIN (rom) and your FLS (baseband) files

I like living on the edge and flashing .kdz. hahha
But this is very helpful!:thumbup:
Awesome tut dude.:thumbup:

Good man thanks for putting this up. I have been flashing via this method since Gingerbread because I couldn't flash KDZs due to a broke CPU. I'm sure this will come in handy for others:thumbup:

This is the best way to make things complicated! )) Just use LGP970 Rom Converter!! Put KDZ in same folder as application and run it! On first question press number in order wich is KDZ file, and after extracting on question about CWM recovery or something like that, just hit N on keyboard and you are done.

Yes, it is easy, but when you do this, IMEI is null so you need to fix it.
What is the easiest way to flash kdz files into p920?

Actually, it won't bomb your IMEI - I flashed the modem firmware several times already - it's the fault of CM10's modem RIL, so updating to V21D/E or V28 is usually recommended. No matter how hard you do, you cannot brick the modem unless you flashed obviously wrong modem firmware but if it was from any of O3D ROMs, you won't even lose IMEI. I flashed V21D modem firmware extracted with LG P970 ROM extractor and I didn't even need to touch the modem terminal.

Whell, i used P970 KDZ Extractor for Official V30A p920 rom and I had a IMEI problem. I did this from v21e and v28 and both have IMEI problems after that.
I think KDZ is the safest way.

This is definitely not the reason u had IMEI problem! I never had that problem and i used it xx times on two different phones. U probably downloaded faulty rom or have windows problem and it didn`t unpack properly. I flashed V28e and V30a with SmartFlash after unpacking KDZ and my phone works normally.

See? The only way to grenade your IMEI is by flashing wrong modem firmware or corrupted one. Thus, repeating what I said, no matter how hard you do, you won't lose your IMEI.

Guys, there have been multiple reported cases of lost imeis when flashing basebands (fls), it has happened to me twice.
Flashing kdzs doesn't create that problem, at least I've never read such a case.

I think some CPUs work better with one or the other. I have to ise this janky Netbook that has something like Windows 7 but its like Windows ultimate or somethn like that. I have tried so many times to flash KDZs properly and it just doesn't work for me and the one time I did get the tools to work I completely broke my network and had to format my CPU. Flashtool however works flawlessly for me and I have never had problems; then again I have everything installed correctly too which makes a huge difference. I had an imei issue once back in the ported SU760 days but I'm pretty sure a factory reset and a fresh base and flash fixed that. Its just what works for you.

Hi daniel.mota,
Your LGExtract.exe from LGExtract-0.2.1.7z works great and wrote an easy to follow tutorial. Thank you.
But, what can I do about the .bin and .fls file? I mean what is the next meaningful step I can take?
Sherab (newbie):laugh:

Hy guys, I've got a problem... LGExtract extracts the cab as well and this one extracts a wdb, a wdh and the dll.
When I try to extract the wdb it extracts a file *.tot how to go through this??

Rename file *.tot to *.bin.

Guys, so sorry for the tricky question, I've read in a Spanish forum that this tool is only going to work for Firmwares not bigger than 1gb, can you please confirm this info? or maybe sharing your experiences on using this with a big KDZ? Thanks a lot in advance

[Q] Is there any APK to exact the boot.img in the phone

I want to unpack the img but don't want to use in my pc(too confused).
so I want to unpack by the phone,
thank you

I don't think there is. Maybe I'm wrong too.
Basically all these boot.img tools are written in shell/bash and is made specifically to run in Linux distros.
Anyways there is an Android app called, Complete Linux Installer that lets you install any Linux OS in your phone. But I doubt whether boot.img tools work, as it needs various library files for it to work.
On a side note, I guess it would be more complex to do it in phone rather than in PC, if there is some way for it to work.

Thank you for your reply, but do you feel strange that the IMG is created by the recovery, so it is rational that there is a tool about IMG building. then why there is no apk. I mean some professional can extract just from the CWM recovery, I think.

need root
if you wanna get boot.img i think you must be rooted.

yes, I root, so I can use the recovery to back and restore,

I think any app that can access zip files in the internal and external memory can extract boot.img.
Like ASTRO File Manager and stuff...

recovery?
You wanna install a rom?
or recovery??
or we speak about boot.img? (Boot img is the boot animation when you turn on your phone.)

Nooooo
boot.img is the kernel (zImage + Ramdisk packed into an image file) that lies in the /boot partition
@ OP - If you want to extract boot.img itself, there are various methods and from CWM recovery like you said. I thought you were mentioning about how to unpack the contents of the boot.img say like zImage, Ramdisk and other files.

It could be done using this post http://forum.xda-developers.com/showpost.php?p=20227868&postcount=1124 and a hex editor from play store on your phone. But would be even more fiddly than on pc I would imagine, unless your phone has a largish screen. It could be done though.
If editing the ramdisk, you would need to unpack and repack after editing, which usually requires linux. I recently found http://forum.xda-developers.com/showthread.php?t=2036528 for PC, but have not had a chance to try it yet, seems best solution for OP

I unpacked my boot.img with android kitchen, but on recompiling its size went 5mb less and on flashing it directly enters fastboot.

The android kitchen is no longer continued from 2011, so the binaries haven't been updated since then.
I suggest you use "android image kitchen"

I don't think you need them. Unpacking and packing boot images is pretty straightforward since Huawei's boot images have the same format as stock Android AOSP boot images. You can use the utilities you mentioned to unpack without need of any ELF file.
