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.

[Q] Bootloop, and factory reset is stuck [SOLVED]

My device is rooted with towelroot, I installed supersu afterwards...
before bootloop I installed fontexplorer, and installed few fonts, it asked me to reboot, i rebooted, and now it just bootloop's all the time, LG animation and vibration, I can't get into fastmode, tried all kinds of button combinations..
When I try to factory reset, after pressing yes it shows erasing, and then it's stuck on boot logo, not animation..
Download mode is stuck also, just shows 0% but at least then pc's device manager shows com device found
How to fix this ?
All this happened after I rebooted my phone, before rebooting I installed few fonts with Font Installer ★ Root ★(com.jrummy.font.installer) app

THIS guide will help, you've softbricked, only in this guide you will of course need the dll and tot files for your phone and not Sprint. As long as phone comes on,computer recognizes it, and, it goes into dl mode, you should be good.

G3s to me are finicky about changing or modifying. I modified one build prop setting, rebooted, same thing as op, mine wasn't bootlooping tho, but stuck on the big red 2 screen. Flashtool is your only friend at this point.

I just went into download mode and used LG Flash Tool 2014 to flash to stock firmware..

I think I read back when I was unbricking that .KDZ files have to be converted to .tot, to use with this version of Flashtool.

Quick Question
Hey guys,
I am a bit of a rookie with rooting and i have an LG G3 for tmobile. I rooted my phone and had TWRP installed and accidentally attempted to install a software update and it soft bricked my phone. Here is my problem-all of the solutions i am finding for this issue require a PC, and I, unfortunately, am only running on mac software. I have no way to get lg flash on my mac and to make it comparable with my phone. Is there ANYONE who can help me? I am at my wits end and CANNOT believe I was so stupid as not to make a backup flash but I, as per usual, did not think about it at the time. If anyone could help me, I will be forever in your debt.

I believe you can run virtual Windows on a Mac, not sure if it works with Flashtool though.

Unable to boot my rooted LG G3 S (beat), stuck at lg logo.
hello everyone. I recently rooted my lg g3 s (beat) D722K. After a few weeks I was trying to install apps as system apps using ES file explorer for which I had to copy the desired apk in the system/apps directory and restart the phone. it worked for a few apps (which I successfully made sys. apps) but not for a majority of apps . Everything was fine until now . After that I wanted to normally install an apk but the phone was unable to install it showing ' application not installed' . Then I tried to install other apps but got the same result . I decided to reboot my phone but it got stuck on lg logo and won't boot .
I tried to factory reset it using hardware keys but after wiping all the phone data it again got stuck on the same sucking LG logo .
I also tried to update firmware by connecting it to windows(8.1) pc in download mode which didn't work either. The firmware download got stuck at 0% everytime I tried.
please help me in getting out of this issue . I will heartily appreciate any help regarding this issue.
thanks.. in advance.

[Q] Stuck at fast boot LG G3 F400L

Hi all,
Long time user first time posting a thread [sorry couldn't help myself]
Anyway I have a LG G3 F400L and I accidentally installed D855 rom on to it [AndroidNow_HD_8.0_Lollipop].
I have tried flash tool to flash the correct firmware but to no effect it now detects it as D855, so I cant install the F400L firmware using the F400L dll. I am installing an older firmware i.s 10e I have also tried 20f for F400L but the new flash tool doesn't recognize my phone, I have tried different USB ports and a different PC with Windows 7 32bit still nothing.
I am using Windows 8.1 64bit.
Regards and thank you for the help.

Anyone, please help.

Use cwm or any other recovery backup to restore

Thank you for the response. I do not have access to recovery, only download mode works.
Update: I have tried using a general Dll to flash TOT file via flashtool but it doesn't let me error CrossDl [D855] to [F400L].

I had this and I set for 4 hours figuring out how to fix it. ( I had not accsess to the download mode first only to hard reset which didn't work and the "Fastboot mode started")
If you have access to the Download mode that's perfect, Follow this Tut:http://lgg3root.com/lg-g3-root/how-to-unrootunbrick-lg-g3/
Please make sure you download the correct TOT file for your phone.

Thank you that did work sort of, I was doing the same thing but someone in the comments referred to a modded DLL for the flash which did the job to some extent at least.
Its back to stock but stuck at McAfee activation, requires a pin which I do not have nor have ever created one, and now a Kill switch has been engaged and no more download mode. Out of the fire into the frying pan is what I feel like right now 100hours and 33mins without my G3, but who is counting.

That's sucks where did the McAfee activation came from??
Have you tried a hard reset ? or can you access the fastboot mode again ?

Nothing, no download mode or recovery. Boots up asks for language selection and then McAfee pops up of PIN. I am talking to McAfee support hopefully they can help.

Goodluck with that!

Thank you all.
Finally fixed. Just needed to be quick, the McAfee app gives you about 30 secs to do your thing then it pops up for pin. I opened up the McAfee app -> setting and changed the pin .

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.

Replace the battery

I have the same problem and i got into the problem for the same reason.... the random rebooting that everyone says is down to the battery is something more sinister... i have tried 4 different batterys that work perfectly and it still happened i flashed a kdz and now i have a bootloop and no OS none of the other kdz files work neither do the tot files and lgup doesnt recognise my device... stuck...

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.

LG G4 Stuck In Firmware Update - Stock Reset?

Hi, recently decided to reset my phone back to stock as I had some trouble with a few programs after resetting my phone. I tried factory reset but the programs didn't work so I decided I would try to just restore to stock and start fresh. I followed a guide on how to do the stock restore using LGUP/LG Flash Tool. I followed the guide and put the KDZ File into the program and pressed cse flash. The program worked till around 12% then it got stuck and just didn't work anymore. It said error so I kept trying over and over as some guides on this problem said to keep trying.
Nothing has happened and my phone is now stuck on firmware update screen. I have taken the battery out multiple times and replaced it back in and turned the phone on but it automatically goes to that screen after showing the lg logo. I have tried the volume down and power button factory reset but that doesn't work and tried getting onto download screen if that was any help but couldn't do that either. Now I'm stuck here... Any help? Don't have any other phone and can't afford to get a new one so I would like to try fix this anyway possible.
After failing the flash update thing the program says failed my phone says 0%. It went to 1% once and then just went back to 0% after it didn't work. So don't know if it's been changed in anyway. All help appreciated.

Did you have LG up set at refurbish or upgrade.....

I did refurbish first as I wanted to start new and it didn't work even though I did it a few times. I tried upgrade after and still nothing. Also have tried Uppercut and that does the same as normal LGUP.
The furthest % it got to was 19 on the computer and 8 on the phone and then it just stopped again. It usually stays between 11-19%. But most of the time 11%-16%

Have you made sure that it is the right region......
Try to down load just tot file and try that....
