LG G2 D802 - Hard Bricked whilst trying to flash KDZ. - G2 Q&A, Help & Troubleshooting

Hi All you very clever people.
This is my first post, have been watching from the shadows for a long time on xda, but have finally met my match and have to ask for help!
I had the (I believe) HK version of lollipop 5.0.1 KDZ that was 'leaked' a while back (possibly the first LP one out?), liked it for the most part but wanted to go back to KK. Tried to flash via KDZ again the KK KDZ. Unknowingly I tried using a USB3.0 socket and it didn't work. I then unplugged the cable from the computer and plugged it into a USB2.0, still didn't work a few times.
Foolishly I thought, 'I know, I'll reset the phone and try again!'. This then stopped me form getting into download mode!!!
I can still get to recovery fine but resetting just gets me back to a black screen. I am getting the 9006 error of bulk usb mode or something. I have tried SRKtools and still cant get to download mode? Is my best bet finding the corresponding .img files for that rom and flashing them in ubuntu?
On that note, does anyone have a link for that KDZ image by any chance. Can't find mine on my computer anymore (again foolishly probably thought, 'won't need that any more, phone is working!').
Also wondering if this has erased the rom on there of if it is just related to boot? It won't boot into the rom at all just black screen after LG logo?
Any help will be greatly appreciated! :good: :good:
Cheers

KitKats are 20x, I think. But you should know that as you already tried to flash one.
Sorry I'm new so I can't post plain links.

Give us some info about your phone please

[Q] Problems with LG Official update software

Hi there,
I installed the LG software update app, and when I plugged in my phone it did some checking and said that there was an update available.
So I clicked OK, waited for ages for the kdz package to download, and then it started the update.
Problem is, it gets to 14% on the phone screen (20% on my computer) and then it hangs for a while. Eventually the PC app says "upgrade stopped due to an error". Now my phone is constantly stuck on the Firmware Upgrade screen, even when I restart it, and I can't even ADB onto it, or use Linux to view it (as mentioned in a different post).
I can't get into download mode or recovery mode... just this Firmware Upgrade screen.
Any ideas what I can do? I stupidly thought that - as it was an official upgrade - it wouldn't screw up my phone... how stupid do I feel ???
Anything I can try? My phone is an LG G2 International (D802) version.
Thanks a lot,
JM

Hi there,
Nope - can't get into any other mode than this "Update" mode... gonna try a few tools. Was trying to salvage my stuff, but it's not the end of the world to wipe it.

Problem solved! Try the .TOT method shown here:

[Q] KDZ Flash issues

Hello everyone,
So I basically made a noob mistake. I had a custom recovery installed on my d802 and I opted to update the software via the LG apps. Now I am stuck at the LG logo on start-up. Normally this wouldn't bother me so much, but the problem is when I try to flash the original firmware with the flash tool. I have looked everywhere and haven't found a proper answer (forgive me if I missed a thread).
The problem is that I get an error saying your phone is disconnected when I'm pretty sure its not, and the phone screen displays "fastboot: processing commands". I have tried a different usb cable, a different pc with different version of windows. But unlucky so far.
Apart from this though, I was wondering if I could flash the Italy lollipop KDZ? I am in Germany and since I have the same model number (D802) I might as well give it a try. What are your thoughts?
Any help from you guys is highly appreciated.

Hi!
Yes, I'm pretty sure you can flash the Italy .kdz, 'cause it's correspond, basically, to the open version. I think there is some bloatwares, but they can be remove by root. you can even flash the spanish .kdz, but there is vodafone's bloatwares inside.
But if you're stuck in fastboot, I don't know if you can access to download mode. Can you describe actual state or your phone? Do you have access to recovery? Download Mode? Can you boot?

Whenever I try to move into download mode it automatically takes me to fastboot. I cant access recovery or hard reset. But yes the lg logo does come up and thats all, it evens goes as far as the second time the logo comes up and the leds come on. But thats about it. It shows download mode for a little while and then automatically goes into fastboot.
Thats all I have right now.
Well this is not pretty. I just realised my phone isn't getting into download mode. I was under the impression that getting into fastboot when connecting phone to pc is the normal case for everyone. But im supposed to get into download mode rather than fastboot, eh?
Now i'm really out of clues. Appreciate your help devs!

lg g2 critical error
I have done a flash to my g2 32gb d802 and it suddenly entered into critical error not going into any of thefastboot mode or download mode even though it is giving me options.....please any one help me out to get my phone back to normal ........
PM me if you guys need help.
I had the exactly same problem, and I had to go to afterservice center to repair. Engineer told he would wipe everything and install new rom. but He failed to write rom so he simply changed mainboard.
At first I had thought about open my g2 and makes it go into qualcomm download mode by short-circuit.
the reason I didn't was my warranty was still available.
I tried every method to make it boot into recovery or download mode but I failed. In my opinion, you may try short-circuit method for last solution. In this situation, even linux doesn't mount rom's storage section. Only if you can make G2 recognized in Linux, G2 will revive.
good luck.

The best way to go if you do not have a warranty is to short circuit the board and get into Qualcomm ... 9006 mode. However, when you get the demigod error plug in you usb and click up and it should start download mode even though it doesn't show it.

How do you short the pins? There's a guide here on xda but it's so difficult to undestand. I need to know how can I short the pins.
it should start download mode even though it doesn't show it.

No, it doesn't. I try to use flashtool but it doesn't recognize the phone. No download mode in any method I tried
I got into this error after I had previously recovered into qhs_usb9006_bulk mode from a hard bricked D801, by shorting the capacitors on the main board. After entering qhs_usb9006, I used srk tools 2.1 for my phone, and after they finished, I tried entering download mode, only to get into this error. I really don't know what it is to say about this. Everything turned wrong with this phone, it went from simply failing a .kdz, to stock .tot, to hard brick, and now to this error, whereas it should've just enter the download mode, as for the 99,99% of the others. Any help would be really appreciated. Thanks.
L.E. I shorted the capacitors again (the one i the middle, like I did the first time, when i got into 9006 mode. 5000 and 5004 didn't work for some reason). This time I got into dload mode, which is 9008. I'll try to recover the phone from here, with this method:
http://forum.xda-developers.com/lg-g2/general/fix-unbrick-lg-g2-stuck-qualcomm-hs-usb-t2933830
i had this problem while trying to return to stock. Fixed it by following this guide http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404 . it needs some hardware tampering though. i tried and tried but i cant flash the phone any other way. the way i understand this is due to bootloader being corrupt.
I installed autorec from playstore solved all the problems
Than you! autorec worked for me too
Can someone post a KK baseband for D801 (T-Mobile)? I'm on D80120a software version with unknown IMEI and baseband (the phone is a D801 refurbished into D802, I more than hardbricked it by flashing wrong .kdz, got it recovered through shorting pins, 9008 mode, got download mode, D80120a stock, root, twrp, after a very long and painful process of about 1 month). Now I have to make use of QPST, but I have to obtain a valid baseband first. Of all links I've stumbled upon, only 5% or less of them are still working, so I only have one flashable modem, in twrp recovery, which corresponds to D801 jb version.
http://downloads.codefi.re/autoprime/LG/LG_G2/G2_modems
cloudyfa kk_baseband_D801 only make my phone restarts like crazy.
I'm simply stuck and pray for some devine help.
Thank you.
Weird enough, I flashed a canadian modem and I got both baseband and IMEI. Why did I do that in the first place? Because I remembered that before all these things happened to my phone, the baseband was M8974A-AAAANAZM-1.0.190082, which corresponds to D803. So I said to myself what can happen by flashing the wrong modem? Boot loop, easily fixable with the phone in it's current state. But again, after 1 month of trouble with the phone, I'm back to what exactly started it in the first place: phone seem to work OK but it has 2 huge problems: WiFi extremely weak (2 meters away and a wall or 5 meters away and no wall a and I lose the signal in both cases; the 2nd is wit the GPS - 20-30 meters error). No idea how should I adapt the radio to Europe region (by keeping the canadian one and change the settings, if it's even possible/fixable this way or if this even does make any sense).
I had to do a hard brick fix to get it into the QSUSB mode to flash TOT.
Have you tried using LG Support tool to put it back to stock?

My LG F800L doesn't turn ON after H918 kdz installation! HELPPPP

Hello.
First, sorry for my bad english..
I got the F800L model and I rooted the device following the guide of Dirty Santa.
One day I read in forum that someone was able to flash H918 rom to the F800L device.
So I tried to do same.. but with the mistake of not backing up my original rom.
When I tried to flash the H918 rom through TWRP, it installed well, but when it booted, it just remained hanged in LG logo.
I just left it over a day waiting if it pass the LG logo. But it didn't.
Then I searched for the fix and read the guide about restoring the bricked device through LGUP and kdz file.
So I entered in download mode and connected to PC.
Executed LGUP software and my device appeared in H91810i model instead of F800L. I downloaded the F800L kdz file and tried to restore with LGUP but it appeared error saying kdz invalid.
So I managed to download the H918 10i kdz file and tried again to restore.. and WOW! it completed the process.
But.. Now my device is in worse condition. It doesn't even turn on.
Tried to enter again in download mode but nothing happens.. neither enters in fastboot mode...
Pulled out the battery and reinserted, and tried to turn on but nothing happens..
Can anybody help me please???
I think you destroyed your phone
You should get it to repair service
lol, u just facing the same problem with me, i did exactly the same what u do, was looking around for solution, but nothing really helpful out there, the only way i found is the method with sd card, u get the debrick img file, burn it to a 32gb sd card with the right tool, put sd card to your phone and hope it will get to downloadmode or fastboot or whatever idknow cause i'm don't have the debrick.img file for F800L, looking for it right now, people say u can get that file from the phone (has same model) that still working, that all i know for now, if u found anyway to fix your phone please told me :highfive:
It has been repeated over and over and over "DO NOT FLASH ANYTHING THAT IS NOT MEANT FOR YOUR DEVICE" and also "FLASH AT YOUR OWN RISK". Both of them together makes it pretty clear that you shouldn't have flashed something that was meant only for the h918 into an f800l variant. Developers dont write this down as fancy words or for fun. They do it in order to let everybody know that if flashed, it could easily alter your system in such a way that it might never be fixed except by the company itself. By flashing something that wasnt meant for your device, you are trying to override the system with an image. And if the developer never made the source compatible with yours, then software and hardware will be contradicting each other. The motherboards of the phones comes for its specific variants and only developers can alter an image of a system to make it somewhat compatible with the variant.
Now, lets hope you get an answer to how to fix it because LG wont be fixing it for you since you voided your warranty by a) the simple fact of unlocking the bootloader (which is pretty easy to identify since it shows the warning sign when you turn the phone on), and b) you rooted the device. And LG wont work with neither of those. Unless.... and this is a maybe because i dont know if they would agree too (if you pay the sum they request to fix it, which i assure you it will be more that $100+ maybe even significantly more). Then they fix it for you.
I personally made a backup in a separated MIcro SD card i have outside the phone. So that if i have problems with my system, then i just insert that micro sd card and restore the backup.
Good luck!
If the phones screen is blank when you try to turn it on you bricked. Only fix is a replacement. There is NO debrick.img
oh my god, if u stop at the step KDZ tool found your device that H918, I can help you. Just boot to fastboot mode and fastboot the file name bootbackup.img and KDZ tool will found your device is F800L then KDZ normally. Sorry for my bad English.

Stock ROM that is flashable with Smart Phone Flash Tool

Hello,
My situation is very specific, but I try to explain as well as possible. My phone is a LG Magna H500f. I decided to try a H502f Custom ROM, because the hardware seemed to be the same. Wasn't a good idea. Closely as bad as the idea to flash the stock ROM of the H502f.
Now I got a soft bricked smartphone. I can boot only into the download mode, but the Smart Phone Flash Tool (SMFT) and some LG device flashers don't work either. There is one little exception. When the phone is turned off and I plug it into an USB port, it is in the download mode for about one second. This is enough for the SMFT to link in and flash. The main problem is, that there is just the stock ROM in the kdz format. That means you need a LG device flasher to flash it. But they don't work, even not in one second of download mode (I really tried it ). So what I need is the stock ROM in image format (boot.img, recovery.img, ...)
I crawled the entire internet with my private botnet, but I didn't found anything in three days.
I hope somebody can help, so I don't have to endure the consequences of my stupidy.
Greetings, Julian
