Installing a LG G3 ROM today - G3 Q&A, Help & Troubleshooting

Hello guys,
I have a LG G3 d855 EUR (i live in Italy) stock firmware V30c-EUR-XX, no root, no custom rom.
Since i'm pretty new to Android modding, i want to ask for your help because i would install the best custom rom available for my device.
So, which is the best rom? Can i have a step by step tutorial for rooting my device and installing the rom?
I would like to maintain the stock camera quality, i've heard that custom roms may decrease the overall photos quality.
Thanks in advance, i really appreciate your help. :good:

Hello, since this is General.. Question shouldn't post here but anyway, have you heard Fulmics? It is developed by xpirt and will transform your G3 to G5..
You can use that ROM because it is the most reliable ROM i'll ever use on my G3.. Don't worry about the camera quality since it is stock based ROM, you won't lose anything..
Please note that my G3 is korean variant ( F400L ) and not international ( D855 ).. So my choices is a bit limited here.. Don't worry tho because Fulmics support most variant of G3's..
Let's Start!
How to root? First you need to go back to Lollipop, How? If Sony, there is Flashtool but with LG, we can use LGUP and flash the stock kdz/tot there.. Please download the right kdz for your device btw..
And there is many ways to root such as Kingroot or OneClick..
Note that, if you're using Kingroot.. Don't mind about their bloatware because we're going to update to Marshmallow anyway..
After it is done, you need to install TWRP.. You're so lucky because there are many way to install TWRP and the most easiest way is using AutoRec
( BEWARE, IF YOU INSTALLED THE WRONG VARIANT FOR YOUR DEVICES..THIS MAY LEAD TO HARD BRICK! )
AutoRec can be downloaded from Playstore, you need to find the right one for example.. You got D855, so you need to download Autorec Lollipop for D855.. Don't install the one for F400 or else, goodbye to your G3 forever.. Yup, easiest way can be the most risky way to go..
While busy with rooting and installing recovery, download the ROM you want.. As example, download the latest Fulmics 6.9 ROM for G3 and transfer it to root directory of your SD Card..
After you have TWRP installed, boot to TWRP.. If you found it is hard to boot to recovery with those stupid combination key.. Just download an apps called ... Boot.... hmm.. whatever it is.. I'll forgot, just find an apps that can help you boot to recovery easily i guess..
If you succeed to boot to recovery, congratulation.. Now do wipe data cache and install the ROM ( Fulmics 6.9 as example ).. After that, reboot the device and enjoy!
Since my G3's is already dead a long time ago ( bluescreen and flicker ), that's all i can help by typing all of this using my G4.. Goodluck!

Are you sure there is no QFUSE which is blown when you downgrade? Because i've read and heard about it. It's dangerous to downgrade, someone got stuck on 5% and had the secure boot error which is an indication of QFUSE.

The downgrade is mandatory for rooting the device, right? Is there a root for Android 6.0 too? :/
I'm a bit confused...

I've done that a lot of time with my G3.. No QFUSE problem here and this is the first time i've heard that.. What is QFUSE?

I am not aware of any root method for V30 based roms but there could very well be.

QFUSE was supposed to be a downgrade protection which triggers when someone flashes in download mode a version of android lower than the current one. I have no idea why, if you access the hidden menu, and find DRM, you find QFUSE there. It was supposed to, like said before, be a fuse which is triggered by a downgrade.

new to lg g3 questions

hi guys im new to the lg g3 (well any lg phone) just a couple of questions
from what ive read there isnt many roms due to the locked bootloader will the bootloader be unlocked in the future?
i have the D855 uk vodafone model is they a working TWRP or CWR for the g3?
ive rooted so does this mean i can at least remove some bloteware?
thanks guys sorry for questions :victory:
from what ive read there isnt many roms due to the locked bootloader will the bootloader be unlocked in the future?
Probably yes, if the @thecubed and others beat the protection (last post - http://forum.xda-developers.com/ver...3-vs98510b-t2890349/post55729952#post55729952)
i have the D855 uk vodafone model is they a working TWRP or CWR for the g3?
There is only Tethered version and I would not recommend to use it. It's for advanced users only and it's not a "real" recovery. More on http://forum.xda-developers.com/lg-g3/general/recovery-twrp-2-7-1-3-t2831668
ive rooted so does this mean i can at least remove some bloteware?
Yes, you can... , or freeze it. If you will the cause softbrick, use LG Flash Tool 2014 and flash in NORMAL mode latest stock ROM you used or use LG PC Suite. After this you need to re-root it. (http://forum.xda-developers.com/lg-g3/general/guide-unroot-ota-using-lg-pc-suite-pc-t2802286)

thanks for the replys if the bootloader doesnt get unlocked then thats going to destroy the g3 for development isnt it
is they a way to flash latest stock rom and get off the vodafone branded rom so i at least get all the latest OTAs?
Not sure I understand you question, but if you mean, whether you will be able to update the phone via OTA in the future, it depends.
If not or if it will not work, unroot your phone, install OTA and the re-root and you should be fine.
But still - all of that is already described in dedicated threads, don't be afraid to take a look around. :fingers-crossed:
As for the development - I guess when it will not get unlocked, it will be from my perspective one of the most wasted money on Android phone for many.

lol sorry what i ment is im on a vodafone branded firmware now and i wanted to flash a unbranded latest uk stock rom so it will be first to get OTA as branded firmwares can be a bit behind is it possible?
thanks again:good:
I don't think so, but someone else should confirm it.
Eg. you can download FW based on IMEI (http://lg-firmware-rom.com/download-firmware.php?f=YOUR_IMEI_HERE), not based on whether it's branded or not.
But still you have option to use the tools like LG Flash Tool 2014 and simply flash latest firmware you want (for your variant)

I know its confusing but you can only flash TOT files with that tool - if you get your FW via the imei cause its a KDZ, for KDZ flashing you need to use this tool...

Help new to this!

But i am stuck i dont know whats the best way of rooting this phone i have tried booting it into stock recovery mode but it just dont work.

Currently using android 5.1 on lg stock rom

Have you unlocked your bootloader ?
No not too sure how to do that. Any good threads you guys reccomend.
Many thanks
So I know this is scary for you and because it is something new, therefore be sure that you want to live with the responsability if something goes wrong.
Now, the next forum thread tells you how to flash an already rooted image BUT, and this is very important, this works only if you have the version 10c installed (Check in About Phone>Software Version)
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
If you have the latest version of the software (20a) the best thing is to unlock your bootloader, void your warranty in the process, and flash a custom recovery. After that, you just need to flash the SuperSu zip file and you will have root.
To flash custom ROMs, just access recovery and flash the zip file of your ROM.
I'm using the unofficial CM13.0 and works very good for me, but I do miss the official camera app.
Thankyou very much for your advice okarr. Will look into this

Help, I rooted my phone and I get a warning everytime i open it

Hello
So after foolishly updating to Marshmellow and discovering that all my apps no longer update in the background, i flashed my device to the LG G4 V10D-226-01 software version, the 10D Europe Open from the LG g4 "Go back to stock rom" thread.
Problem is, everytime i open my phone i get "Warning: Current version is not available for user. Cant find matched cust for Nt-code mcc/mnc[22601],subset[ff]. I have looked both on google and here and everything i found was for the G3 model and it involved using a "custom restore" image. but no explanation on how to use it, its not a KDZ so i cant flash it.
I'm pretty new to all this and everything i wanted was to go back to my Lollipop variant after seeing how Marshmellow behaved on my phone. (not auto updating my background apps).
I appreciate any help you guys provide.
Thanks
u cant downgrade once u go to Marshmallow. Its a security thing tht was updated in the latest firmware b4 Marshmallow came out. Ur gona hav to start all over again wth the latest KDZ b4 Marshmallow
I reformated into a Lollipop KDZ by flashing my ROM from the "Go back to stock" thread. Problem has appeared after i did that. I am currently on Lolipop v10D
nobody has any idea on how i can solve this issue?

I'm also interested in this answer. The only reason I haven't updated to (any ART) rom is because I'm unsure if I can just restore a Dalvik backup without issues. The only way I would attempt is with TWRP.
i tried doing by Flash tool and it gives error like 0000008
bring up the post!
Curious as well. I'd like to get root.
Windows user not sure how to do it on Mac/Linux
by MM to KK I assume you want to take the LG G3 D851 from android 6.x down to 4.x
here goes...
----
http://lgg3root.com/lg-g3-stock-factory-firmware/
http://lgg3root.com/lg-g3-root/how-to-unrootunbrick-lg-g3/
use the LG Flash tool plus the two files, follow instructions on that second link step by step.
LGD851_20140611_LGFLASHv160.dll
LGD851AT-01-V10c-310-260-JUN-20-2014+0.tot
That takes you back to the 4.x kitkat stock ROM, not rooted or anything.
----------------
To go north from there back towards Lollipop or MM you can at this point use
http://www.download3k.com/Install-LG-Mobile-Support-Tool.html
B2CAppSetup.exe
Install it, will put an icon on your desktop, plug in your phone, open the app.
It's pretty much automatic, it updates the ROM from KK to Lolli, then if you hit "OK" it will update from Lolli to MM
- I just got both of these steps to work in the last 24 hours.
I'm still trying to find a valid "Root" method that doesn't ask me to install a funky ROM.
I went from a KK stock-rooted(TWRP 3.0) rom to the MM 6.0 Rom, realized I didn't really want to set everything up again, restored my KK backup. Only problem was I had to reflash the modem. That was a couple of days ago and the modem was the only issue.
I'm unsure about flashing a new/clean KK rom over a MM rom though.

I think I missed a step, in KitKat this phone needs a special command thrown at it so the memory cards will be read/write.
On the play store SDFix: KitKat Writeable MicroSD
I think that might be what I was missing last weekend. My phone is currently on MM but I can't root it with any method other than Kingroot and Kingroot is Bad News.
Yes. It's possible!.

First downgrade to kitkat (with a d852 tot or kdz), then root, then use autorec. After that you can flash what you want.

Pretty sure you just did something wrong. You say your device is a D852 (from your software version), the fact that a D852 kdz or tot is not compatible with your D852 because it was manufactured in 2016 is very unlikely. You also said that your motherboard was "fried" when you tried to downgrade (which is again, VERY unlikely), if your motherboard was fried you phone would be dead right now.
"now i want you to ...(blablabla)", don't ever say that if you want to get some help.

I said it was unlikely that the kdz or tot wont work because your phone was manifactured in 2016, not that your phone was manifactured in 2016.
That being said, I guess you don't understand really well english and that's causing some misapprehension.
I was not rude or anything, I was just trying to help you.
Have a nice day, I wont answer anymore.
I strongly recommend this thread is closed.
