you must download tot rom file then flash it using flashtool

I'm a complete newb concerning flash/installing software and especially reverting back to 4.2.2.. I have the D802 International version (bought it off Amazon) its the UK edition I believe. I'm trying to find the correct firmware but they are all so cryptic I'm worried I'll download the wrong one ( I have the 32GB version) and brick my phone..
Is there any kind of reliable guide I can use to do this process? Or better yet some kind of automated piece of software?
Or would it be best to just wait for LG to release an update to fix it?
If it wasn't such a big issue ( I use my headphones every day constantly..) I would wait but I don't think I can..
Any information would help.

[Q] Change LG G2 Firmware?

I have a LG G2 D802 from Dubai and I was wondering if I could change its firmware to another stock LG G2's, South American for instance, or European.
According to This website my firmware would be 6RE/UNITED ARAB EMIRATES_OPEN_16G
I wanna do that because my update center says there is no 5.0 available for it yet, and for many other g2's there is

You have the D802 Model. There is heaps of Custom Lollipop ROMs for you to choose from that are made for/work with the D802 model. Head over to the D802 Development forum and you'll find heaps of threads for Custom Lollipop ROMs built specifically for the D802, or you know.. you could wait a couple months for a official release by LG.

I actually wanted to keep the stock rom, just wanted to update it to Lollipop to get the few new things and keep LG's customization, I kinda like it (and too lazy/little time to toy with custom ROM's as I did back with Nexus')

Oh I'm sorry I kind of misunderstood what you were asking. Have you heard of the Grola ROM? It's a ROM built from Stock Lollipop from the F320K, and it's working great for the D802. Until D802 comes out with it's own official Lollipop release, you might want to check that out .

That is a better option! thanks
But what I was really hoping is to try to change my firmware from Dubai's to Europe's or whatever, just to have those updates more at hand.
Also, any idea if I could flash a radio or something to make my G2 work with my country's LTE band? I can only do that by that secret menu from dialer, not straight from settings (and it works)

Q: How do i find out which exact bootloader version is currently installed?

Hi all,
My "new to me" LG G2 D802 came with stock KitKat 4.4.2. I updated to stock Lollipop 5.0.2 (30b) using the LG PC Tool and rooted the phone by using this method.
According to the OP of this thread i am now running again a KitKat bootloader and a KitKat "download mode" on lollipop.
I would like to experiment with some other kernels and such and have some noob questions here, which i could not answer by searching the forum. Coming from Samsung and Oneplus, the LG world is rather new to me. Please don't treat me too hard
How do i tell which exact bootloader version i am running now?
What do i have to remember when flashing a different kernel (i.e. Dorimax)?
How does the above procedure affect OTA-"updateability"?
Thanks in advance,
Tom

Was this question too noobish? Or does really nobody know? Any hints would be really appreciated!
TIA,
Tom

LG G2, d800 update to Lollipop

Hi,
I have LG G2 (d800) and I live outside US (Europe). My problem is that I can not update my phone OTA. I would like to do it manually but, I am totally not familiar with flashing, rooting etc. If you can point me to some "materials" how to do it, I would be very thankfull. Currently I have android version 4.2.2.

Dude, you have to read some basic things to understand, but to give you a direction:
Here's a generell list of guides and fixes. It has a "root"- and a "recovery"- section. Both are absolutely necessary. Go here first.
Here's a list of custom roms. There are stock-roms, stock-based-roms and completely custom-roms. I prefer stock-based-roms because the devs added some extra features and you have full driver support.
I hope this helps a little bit.

i have read some of there before, but i'm yet to understand it, because my previous phone was nexus 4, installing roms and such was fairly easy, and with this LG G2, there are complicated things even as flashing roms, not all models the same and such, and im afraid to brick my phone because of that, i also have a D801 model - D80110C and i have heared that there are different version of things and such.
anyway, what will be the best way to flash stock lollipop / stock based roms and later flash back to 4.2.2 if something goes wrong? thanks

I just did this, in my experience the best way is
1) updating to stock lollipop
2) rooting via oneclickroot
3) flashing twrp via AutoRec (correct version)
4) flashing twrp 3.x blastagator via old twrp
5) flashing desired rom
There is one caveat though, the root process will install the correct (old) SuperSU that works with AutoRec, but google play may update it beforehand so that AutoRec cannot work. My fix was to install AutoRec before the root and then go into airplane mode and do it all in one go. Also, you should always check if you got the correct carrier version of your software.
Going back to kitkat? This should not be necessary imo, but if you mess something up you can always flash the stock .kdz files (lp or kitkat) via download mode and lg flash tool 2014. This phone is almost unbrickable.
Hope this helps and after years of G2 roms I can finally give something back.

do you have a D801 model? i cannot update to lollipop through normal fota or lg pc suite, it doesnt see anymore updates
i have software version of D80110c, what are the last letters means in it? C/G/ and such,
and also how should i update to stock lollipop rom without bricking my phone? it seems that there is alot of room to ****up. thanks =]

I have d802 and could always update it to LP via LG software update in the phone settings.
10/20/30 is android version, 30 being lollipop. 30a/b/c/d is revision or carrier version I think.
I am not sure about D801, but if I was you, I would try to update to LP via official LG update, otherwise try to root+recovery with your existing kitkat (search the forums) or flash LP kdz from download mode (LG flash tool). Always make sure it works for d801 and your software version.
Then I would install a fast custom rom cause stock LP is rather slow.

i tried to update through lg, but it showed me that i am "UP TO DATE" might be because i bought it from someone who bought it in the US in cincenti bell ( and i dont live in the US, or close to it), the phone have a cincinetti bell rom, so i guess that why i cant update it through the phone like that. and i have a jelly bean 4.2.2 , not even kitkat. it is possible to flash a lollipop kdz just like that even if i have stock never tuched 4.2.2 ? thanks alot
