KDZ file extracts corrupt CAB file

Hello guys,
I upgraded my friend's recently purchased LG Optimus G.
I rooted the phone successfully with TWRP recovery.
I Unlocked the boot loader successfully.
I flashed a custom android 4.3 rom.
The phone was working absolutely fine.
Then, my friend took it home with him, and tried to flash another custom rom (He is a noob).
Now, after rebooting, the phone flashed the 'google' logo with a grey 'unlocked lock' icon and the screen goes blank.
I can not even figure out if the phone is on or not (the soft keys does not light up if I touch them).
After all, I tried to use the UNBRICK method using a guide but the problem is that the software won't proceed after extracting .KDZ file.
I tried downloading .KDZ file using the xda app which asks for phone model and serial number for the download, several times but no success.
I tried downloading the .KDZ file using a URL in which i have to write the IMEI number to get myself a download link. That shows corrupted too.
Can anybody help me to get a working KDZ file?? I think this will get me through the process.
OR
If there is any other possible way, please let me know.
Thanks in advance

I had the same problem. Try downloading several KDZ files cause the programm won't download the good one at once. I got mine at the 4th attempt.

1: Google logo plus unlock icon seems nexus device. May be he tried to convert it to nexus 4. I never tried it nor know if it requires any different way to get stock, so search.
2: download kdz from here choose 1gb or less kdz.

kdz installer we have cant extract files greater than 1.05 GB i do manage to get 1 or 2 files that were 1.08 GB but most wont.
max is 1.05 GB in my experience.

okay, thanks for the information!

Hey! I have done the download, used the update tool in CS_EMERGENCY mode, done with everything. now the phone is stuck on the LG logo..
I put it in recovery mode, and i used the wipe tool which was told in the guide, but the phone again stuck with a lying android bot with an exclamationary sign in a triangle.
What can I do next?

This happens.when you are not reading before. If you would do that,you would see that you need to perform a hard resetafter using kdz updater.
My advice,use the updater again and do a hard reset.on stock it's easy.

Don't know what guides you all are using
Only guide you need
1: get kdz 1.05 GB or less for your specific phone
2: using kdz flasher flash the kdz
3: if your phone boots goto backup and reset and do wipe. If not shutdown phone and do hard reset / wipe
4: root your phone And i mean just root your phone.
5: use freegee to unlock boot and get custom recovery. (If you want this)

U missed the hard reset!! Since kdz is dirty flashing!

This is so frustrating. I've downloaded kdz file so many times from 1.05Gb to a 0.98Gb, none gives a correct extraction in kdz update.

Random Reboots and Bootloops

I flashed 30c firmware with flashtool 2014 over rooted 21a (i think) on my D855 from Greece. I selected the normal flash to keep my files and apps, phone mode: DIAG and didn't clear the update registry. Phone worked normal for a week and then went into a boot loop. The phone randomly restarts and goes into loops for a while and then snaps out of it.
I have tried the following and none have fixed the issue:
-Replaced the battery.
-Upgraded to 30f over lg pc suite hoping it would fix it but it didn't.
-Flashed 30c and 30f over LG Flash tool with CS_EMERGENCY mode and cleared the updated registry.
-LG Flash tool wont flash any older lollipop kdz I tried. The phone screen flashes once but stays at 0% and then I receive a phone disconnected message.
-Put the device into safe mode and used the option on lg pc suite to fix upgrade errors. Didn't fix anything lol
-Tried factory reset. Nothing happened after I selected the yes on the confirmation.
-Tried to use LGUP hoping to install a lollipop kdz but it gives me an error message that I have to select a known model. Restarting the app and the phone didn't work either.
-Tried a guide on how to unroot and return to stock with the kitkat .tot file .
I really have no idea what else to try. Any help would be greatly appreciated.

That's the first thing I tried on my list of failed attempts to fix the problem as you can see... Brand new battery. No change.
DjCaprio tried 4 different batteries as you can see.
This is just terrible!

I tried removing the battery while connected to the pc via usb already. The other trick that involves editing a file requires root.
My phone started flashing the blue screen of death today so I finally took it to LG so they can check it out. Either way thanks for trying to help.

Autorec Bricked my phone, need help

Hi everyone,
It's been some time since I last came here.
I am facing a problem in my LG G3 and was wondering if anyone here can help me.
My phone is D855 was on V21A, Global ROM, rooted. I was thinking about updating to 6.0, so I used Autorec to flash TWRP to backup everything before the update. After Autorec I used terminal emulator (as I always do) to reboot into recovery. And then, the phone kinda died. The screen is always black, no LED blink nothing.
When I connect the phone to the PC it gets recognized as AndroidNet USB port.
I look through the forums for solution and came across this:
http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
I opened up the phone and did the short-wire and my phone got recognized as Qualcom 9008. I used the tool named: BoardDiag and it could copy stuff to my phone.
However, the issue that I faced was that I could not locate the TOT file of V21A. I tried the TOT of V10E and it did not work.
I tried following the method of LGExtract tool to turn the KDZ file to TOT but that did not work either. What happened is that the tool turn the KDZ to CAB and then when I try to extract the CAB it says that it is corrupted. Tried another KDZ from another source and the same result.
What I need now is one of two things:
Either the TOT file of Global V21a
or a working method for KDZ to TOT conversion.
Thanks for any suggestions.
[UPDATE]
I tried renaming the KDZ to TOT but it could not be extracted to the right MBN files.

I am facing the same problem with my LG G3 D850. I flashed a D851 Variant version of the rom and after fixing the hard brick part i am stuck flashing the .tot file because its considering my phone as D851 model. I tried to flash the LGUP_8974.dll to try to fix it and nothing.

Same problem here.
did you find a solution????
Please HELP
.....

I used the same short-wire method and flashed the only TOT I could find, which was 10E. However, this time I flashed the system partition as well. In the guide it says it would take a long time so don't do it. I did it anyway. It took reeeeeeeeeaaaaalllllly long time. Over 4 hours.
After finishing flashing I place back the battery as indicated in the guide and the phone restarted and was stuck at LG screen. I connected it to the computer and it was finally recognized as an LG Android phone.
Then I used the official LG update tool. It detected the phone and said there was an update. I proceeded with the update and everything went back to normal. I even had the same data and apps because I did not overwrite the data partition.
I hope this helps.

[Bricked] LG G3 Rogers D852

I really need help. I've searched around all over the web and on here with no solution. What happened was I tried to downgrade my G3 to stock 4.4.2 KitKat from 5.0.1 Lollipop. The flash tool went all the way to 89% and failed. I took out the battery and now my phone just boot to the Android recovery after the LG logo. When I try to use Flashtool to flash it again, my IMEI and S/N show as null and flash tool fails at 6%. I can't find a solution. I'm able to go into download mode and recovery which the recovery mode only has wipe data to factory.
I'm running Windows 7-64bit. I've tried different Windows version and 32 bit version and none works. I've sent it to a store and they thought they could fix it because they say it is software issues. They couldn't fix it.
I try downloading different Roms variant and .KDZ and .ToT files but nothing works. I've tried both upgrade dl and board dl in Flashtool but nothing works. I've used the D852 DLL, the generic DlL and even the DLL extracted from the .KDZ file.
Please somone help me. There are people with the same issues and either they got it fix or their thread end unsolved. What can I do.

Using TWRmp recovery

LG G3 Back from the dead (was hard bricked) - Need help to start over now

Hey guys
First, a little bit of history:
I own a G6 now, so I wanted to have some fun with my G3.
I rooted it (LGOneClickRoot), installed TWRP, installed LineageOS 14.1 and everything went pretty well.
The problem was that LineageOS 14.1 is terrible, huge lags, tons of bugs, so I tried installing another ROM through TWRP, I don't know what I messed up but I messed up and the flash failed. I dont remember exactly what I tried to flash after that but I failed again and then classic --> Stucked on LG boot logo, no recovery mode, no download mode, nothing.
So I used the popular fix for hardbricked G3, creating a short between test point and ground while connecting it to revive him, and it worked. I went with the whole procedure in BoardDialg and stuff. Kinda surprised by myself that I didnt go full-panic mode creating tons of threads everywhere lol, I managed to make it work even if it took me something like half a day of learning and work.
Now I'm back to stock Android 4.4.2, rooted with LGOneClickRoot again and everything is fine.
I mean... Almost everything is fine, because now I want to be able to install Magisk, and I found that Magisk is for Android 5+.
So there are some informations I need to gather before going further and risk a brick again (please no more short on the motherboard lol):
1- Can I flash a stock Lollipop ROM with LG Flash Tool in download mode using CSE Flash ? Is it a proper way to do it or do I really need to go through this boring TWRP recovery flashing again ?
2- where can I find such a ROM (stock Lollipop for d855) ? And which version to chose ? v20a, v20e, v20f, v20h, v20i, v20p, v20t, v20u, v20w or v21a ? I've been looking for hours now, hard to find reliable informations about all different versions.
Thanks for the read, I hope someone can help me

UPDATE:
I flashed a Lollipop v20f with LG Flash Tool and it's working fine.
I heard that after v20f, newer versions were "harder" to root so I sticked with v20f.
I'm gonna play around with Magisk now and see how it goes.

I'm in the same boat. I also went back to 4.4.2 via TOT. The I rooted and installed TWRP. how I want to restorel my RR 5.8.5 from a TWRP backup. My question is to I have to install the 35B bootstack before or after the restore or at all?

Hi,
Upgrade (LGFlashtool + CSE flash) to V30B
Follow this post ==>
https://forum.xda-developers.com/lg-g3/general/root-twrp-marshmallow-d855-30b-t3286268
Then you can install custom Rom ou upgrade to stock V30N (with root : there is a post about it)

Hey how did you do the unbrick process? I stuck at flashing kdz eventhough i have correct dll and drivers installed

hi,
Try LGUP instead of LGFlashtool (download mode and type *.kdz + select kdz file in LGUP)

Depends if you're hardbricked or softbricked. I was hardbricked so I had to create a bridge between 2 points on the motherboard and reflash everything one by one. I formated recently and didnt keep all these things but I can get into it again to try to help you.
EDIT: LGFlashTool isn't enough if you're hardbricked, you'll have to use other tools and open your phone. First step is identify if you're softbricked or hardbricked, google it you'll find your answer

Mine was hardbricked. I use shorting test point method and successfully flashing partition. Then I flash kdz using LG flash tool 2014, my phone stuck on boot logo. Then I do factory reset. Still same. Last option, I use LG UP. It stuck on LAF info with number on it. Is my LAF file damaged?

Hi,
With Boarddiag try this :
1-EMMC TEST Option "erase" ;
2- then Restore theses partitions and reboot in download mode and flash Kdz.
1)Boot
2)Aboot
3)BackupGpt
4)Boot
5)dbi
