Hi I need some help with my LG G3 D852 phone. I've been browsing around the forum and the web for a fix but I can't find anything so I've decided to make a post. I tried downgrading my G3 to stock 4.4.2 KitKat and halfway the flasher failed. Now I can't flash it anymore because the flasher keep coming up with errors. I use both types of flasher to flash either the .tot file or the .kdz files and nothing works. I tried different variant roms of the D852 but nothing works.

If you f**ed up the download mode, y'u must try flash via fastboot nicely. I don't have much time now, but y'u find this method on xda, it's work for this models probably. You also need the kdz extractor to unpack firmware: http://forum.xda-developers.com/showthread.php?t=2600575. Remember to use the Verizon version of firmware.
I can wait you it you free time because i don't try by myselt the flashboot not recognising my phone i feel my phone is hard brick thk for answer

You can find root for your device under XDA forums. It will be some kind of script file. When you run script, it will automatically unlock your bootloader. After that, you need to flash custom recovery. After this point, you are able to install custom roms. Remember, gather all necessary files before doing anything e.g. Your device kdz firmware or tot firmware files.
dear sir i tried and i stuck on boot, so please guide me with the tutorial
its been hard to flash any custom rom on this device
my model is d686 , its not d680
so try to give a simple tutorial to flash rom this device, its very hard to boot into recovery menu and secondly the recovery menu appears only once because after flashing the rom i stuck on boot logo and nothing else
please help me
and also make any rom which is suitable for this device so we can install on it and use it without legging
thank you
Honestly in the long run getting a newer phone like a nexus 6 will fair better. This phone was an absolute pain for me to manage and ROMs were always crashing left and right. After switching to a nexus 6 I do not regret it.
Hello to all,
I just wanted to help u all who want ot go back to stock rom without haste at all. i just rolled bask form custom to stock without a problem of any kind.
i need to download this: Lenovo make roll back tool
and install it.
run program and go to Flash tab, than go to rescue.
next select brand and model of your device.
Wait till download ROM from their servers and follow instructions they provided.
I think that u can flash bricked models too if your computer recognized it.
i didnt lock my bootloader before i did flashing with this tool and i didnt have any problems with that. i am using single sim XT1771 model.
that does not work for hard brick
I have LG G8 Alexa variant. Model LM-G820QM.
I think ts on latest firmware "qm21e". Right now I live in India so the VoLTE is not working. I tried to cross-flash it to Open firmware but LGUP gave error "Cant change the device(AMZ_US > OPEN_US)".
I have three questions.
Can I cross flash Korean firmware ?
And if so, will i get VoLTE working ?
And my G8 has 2 cams while the Korean varient has 3 cams. Will my cams work with Korean firmware ?
Thank you.
Do you by any chance still have the OPEN_US Firmware?
I've been looking everywhere for it but I can't find it.

I think any of this 2 are OPEN. If not then reply me back I will deep search on google. I happend to found it somewhere but can't remember where exactly.
Thanks for your reply
Unfortunately, neither one worked.
I tried the first one, however the flash tool didn't work because (OPEN_US_>NAO_US)
The second one would not download at all. I don't think it would have worked anyway since my phone is not the Alexa version. It's factory unlocked, purchased from Best Buy.
Hey man, I was able to figure out my problem! Not only that, I discovered one of the NAO_US Firmwares was actually OPEN_US, and that worked for my phone. I am now back up and running, with an unlocked bootloader and Root!
I appreciate your help, and I want to help you if I can.
As for the cross-flashing, you can't do it via LGUP. The only possible way is to download the firehose for your phone and to use the Qualcomm Image Flash Loader(QIFL) tool. You can extract the firmware you want to flash, and load all the images into the QIFL partition manager. There is no guarantee your phone will boot from it, but you can try it. NOTE: Do NOT modify the OP partitions! This will cause your phone to throw an OPID mismatch error and it won't boot!
As for the cameras, you may be able to extract the current Camera APK from your phone and install that on the Korean firmware so that you are still able to use them. No guarantee this will work, and they might work fine with the Korean camera APK, but it's worth doing before you flash.

I see, but I just want VoLTE to work. I don't mind using stock rom or custom rom too. So keeping that in mind what do you suggest? And also, Do you think that your solution " I discovered one of the NAO_US Firmwares was actually OPEN_US, and that worked for my phone. I am now back up and running, with an unlocked bootloader and Root! " could work for me too ? If so do let me know how did you figured that NAO_US was actually OPEN_US. Maybe I can find out one for AMZ_US.
On the box Model : G820QM
SKU : G820QM8 (QM8 stands for AMZ)
Thank you.
I'm really not sure how VoLTE works internally, so I couldn't tell you if using another firmware would actually work for you - but the way I found out one of the firmwares was actually OPEN_US was by extracting it using the KMZ extractor tool someone made. This is how I was able to reflash the partition on my phone that I screwed up on in the first place and created a brick with. Like I said, you could manually reflash all those partitions one-by-one in QFIL, but i don't recommend it as it may not even work and could potentially brick your device. It's really up to you in this case, if you'd like to try though:
Download the firmware you want to try, search for KZM extractor on Google, download QFIL and all of it's prerequisites, and finally the firehose.
Use the KZM extractor and place the firmware inside of it.
Once it is done extracting all the files, put your phone into download mode and open QFIL
NOTE: DO NOT FLASH THE PARTITIONS WITH 'OP' IN THEM! Your phone won't boot for sure!
From QFIL use the firehose file and manually, one by one, sort through the output files of the KZM extractor and find the partitions that match their name and flash them with the file.
Zero guarantees this will work, and you may end up with a brick for a phone at the end of the day, but if you're that desperate it just might work.
Hi there.
I am still looking for solutions for VoLTE to work. I googled a lot and came on this post " https://piunikaweb.com/2021/06/07/unlocked-lg-g8-thinq-now-supports-att-volte-after-april-update/ "
Mine is Amazon version "QM8". Yet I did received april update via OTA. But still no VoLTE. I can OEM unlock from devs. Can I flash AT&T "QM7" on Amazon "QM8" ?
What do you think of this please let me know.
Thank you
VoLTE seems to depend on files in the OP partition, so crossflashing other partitions but not OP will not get VoLTE to work. LGUP will not allow crossflashing.
See my experience to get working VoLTE and Wifi Calling: https://forum.xda-developers.com/t/lg-g8-volte-fix.4113291/post-85455109
You will need to be bootloader unlocked and rooted.
