D800 question

I'm kinda lost here. I'm looking to buy a D800, but wanted to know if root and leave the phone free to install aosp roms like CM11 will be possible and not complicated as hell. Wich are the steps I should follow to root / unlock, install twrp, and backup the original rom? (To later install CM11)...
Please any advice, links, etc will be greatly appreciated. Cheers!

The phone itself is good but the stock software is annoying. There are stable aosp roms available, but they have all very bad Cameras and inferior battery life. So basically most people would be forced to use the crappy lg stock rom anyway. Rooting is very easy as well as recovery

Oh that's bad news... had the idea to flash it with CM11 (while 12 is under development), or G3 roms, some people had told me this phone were good with AOSP roms... It's only the camera that does not work as intended on aosp roms? No fix for battery?

I have D800 and it really isn't as bad as people make it out to be. I can get 12 hours of usage on CM11 with 4-5 hours of screen time. Stock Rom is fine but then again I use the T-Mobile stock Rom on mine when I'm stock or CloudyG3 Rom. Right now I'm using Flyme OS Rom and I started this morning at 45% and was at 7% after 12 hours of work and had 4 hours of screen time.

Yes I'm about to purchase a d800, if it is good with CM11, then its good for me. Maybe later it will have lollipop roms and that will be another era... Thanks for the answers! Cheers.

Hey FedericoUY, I received my phone about a month ago and I'll go through my journey from all of the likely problems and what's required for unlocking, rooting, installing a rom for the first time on this device. I'll describe the benefits/disadvantages from the different rom distributors recommended for this device. Until a few days ago I would have agreed AOSP was better left avoided on this device, and why CM11 is still not recommended for the G2.
When I received my G2, while I had the intention to flash it. I was gravely disappointed with it, because of the shocking software and default setup. But it's become my favourite phone since. I too thought CM11 would do it for me, it really didn't on this phone. And the display & specs make it seem extremely outdated, not to mention none of the phone-specific features really worked.
(In order of events)
Sim Locking for AT&T (do first)
By default it's locked, as I imported it through the US and without an account for them I had to purchase a 3rd party unlock code for $2. Strangely I had to keep it unlocked on the stock firmware for a certain amount of time (tried a day) before it remembered the unlocking when flashing a custom firmware.
Rooting (do secondly)
The only method which worked on the latest G2 stock rom was to use "Stump Root" in the "Brute force" mode as the latest rom version didn't have a pre-configured rooting routing.
Installing a custom recovery (do third)
The only method which worked on the latest G2 stock rom was an app called "D800_AutoRec.apk" which just installed the latest TWRP recovery, from there I could flash anything.
Which roms are decent for the D800?
While personally I've stayed with more AOSP roms like CM and AOKP, the best rom & kernel to use in terms of performance/battery life and phone specific features is not the stock G2 software nor AOSP. I'll explain further why.
For the kernel, the arguably most matured and feature rich, battery friendly and performance suited kernel is the Dorimanx kernel. Which is unfortunately only compatible with stock G2 & G3 roms.
With this in consideration and all of the improvements in the G3 firmware, fully supporting this phone's features, makes the G3 roms peoples choice, in particular CloudyG3 targeted for the G2.
When it comes to AOSP like roms, there is two okay kernels which are compatible with CM and the other is only compatible with AOSP roms, with a few exceptions. Both of these kernels have poor battery life in comparison and produce a lot of heat, not to mention lesser abilities in terms of tweaking (overclocking, underclocking rate, faster charge, etc). It generally only gets worse from here using rom released kernels. It's fairly uncommon for features such as double tapping wake to work, and the lack of on-screen keyboard usability improvements.
However, Lollipop has turned things around. While not flossing as much battery life savings as CloudyG3 with the Dorimanx kernel, performance, design/look (can change Google keyboard to old theme) has brilliantly increased. It's been the only close to stock rom I've ever been largely happy with. Despite not having any real CM features and a few bugs at this moment in time.
Therefore, if you like the ability to tweak and charge faster and overclock a lot with great battery life I suggest CloudyG3 and Dorimanx. If you want an AOSP rom, I'd use Lollipop. If you want a full featured stock rom with a nice kernel, I'd wait awhile and opt for CloudyG3 until lollipop roms mature. For a battery comparison, the stock G3 rom with a custom kernel lasted me 5-7 days without charging, with CM11 I can only get about 1 day if I'm lucky.

[Q] What is the most stable AOSP/CM-rom for D802?

So basically, I've been going back and forth between different custom ROMs the last months but I've never found something that's really stable.
Either there's random reboots, lag or apps force closing.
So what I'm wondering is; does anyone have experience with a custom ROM that's rock solid stable? It has to be Lollipop, but I'd give up 5.1 for a really stable 5.0 ROM.
Oh, and please don't suggest LG stock ROM, I can't stand that.
I really appreciate some answers! Make sure to write what ROM you're using and the release number (or date if it's a nightly).
Thanks!

Anything CAF as it's using the same device source. Aside from that pick your flavor.
Also no 5.0 roms are stable for this device, unless you mean stock. But you mentioned you didn't want stock, so...

Have you tried Euphoria-OS? It's pretty darned stable, and it's 5.1 as well. You can get the official version by tsunamical that uses a CAF kernel (Qualcomm+CM), or the unofficial version from dr87 that uses the stock LG G2 LP kernel.
I've been running the official 6/10 build for a few weeks now and it's been really stable. A couple of random reboots but nothing to worry about. I would be running the newer build, but I dirty-flashed it and it went a little wonky so I restored the nandroid, and then tsunamical said he was going to post another one in a few days, so I decided to wait for that before doing another clean flash.

Fastest STOCK BASED ROM for LG G2

Hello everyone,
From few weeks Im using Cloudy G2 2.2 ROM + Dorimanx kernel with performance mode - and unfortunately this ROM is very slow, few days ago I bought another LG G2 D802 for my friend, it comes with android 5.0.2 stock. Of course this system is completely clean but difference with speed to cloudy g2 2.2 (andorid 4.4.2) is very big. This 5.0.2 rom is much faster, Im asking this question because i have read a lot opinion that older cloudy rom and older stock based roms are more stable and faster than lolipop. But now I see that is not true.
I need stock based rom because of camera (for aosp is very poor).
Which stock based ROM is fastest for LG G2? Thanks in advance for your opinions

cloudy 3.3 + xceed kernel imo

I will try this ROM, any other suggestions ?

From my experience the fastest stock based ROM on the G2 D802 is CloudyStock 2.7. Kitkat is much faster and memmory management is night and day comparing Kitkat and Lollipop. Stock Kitkat based ROMS are optimized to run much better on G2 than Lollipop ROMs. Its interesting that Cloudy 2.2 is running slow for you, maybe try to reflash and use the default kernel that comes with it without changing any kernel settings. This is the ROM I am using ATM and it is one of the fastest. Also try MIUI 7 based on stock Kitkat, Cloudyflex, Cloudystock as I mentioned and other stock Kitkat based roms if you want speedy and snappy performance. Cloudy 3.3 is also good if you want Lollipop but it will bog down after a while and only data wipe can restore its snappyness although frequent reboots can improove memmory management. Dont use Dorimanx kernel it always slows my phone down no matter what settings I use, IDK why. Also if you are using G2 or G3 tweaksbox try disabling it, some settings can slow down your phone. The same goes for Xtana and similar apps thet change systemui and framework apk. Unicon app for changing icons also slows down any OS. Try to run as stock as possible for the snappiest performance.

Good idea to disable g2/g3 tweaks - I will try it, As I remember, on original kernel system was similiar slow. Maybe I just need full format all data/syste/ etc and install clean rom from beginning. Also I will try to record speed of my phone just to comparsion, maybe it is normal but just for me means slow? I dont think so.

I dont think so either. Also when installing choose odexed in aroma, this also affects ROM speed, app openning speed and boot time. Deodexed is not necessery as you can easily theme anything with G3 Tweaksbox even if your rom is odexed. Try shuffling trough D802 development section and you will find a couple of great Kitkat based roms like Coqueror rom or stock 20f prerooted kitkat rom.

Sorry but it's not clear, you mean that is better to install odexed or deoexed rom on beginning?

Its better to install odexed ROM.

Best thing you can do really is flashing a non stock rom...the difference is insane. The major drawback is the camera...the quality is considerably lower. Battery life is more or less the same! Stock lollipop from LG is so bad...even with xceed kernel

You are absolutely right! I know this, camera is just one reason which keeps me with stock rom. I used cyan 11 before and diffrence was huge, I mean camera is so bad but speed sooo good. I think lg g2 is not complete phone for me because of this. Camera is something very important for most of the ppl, and this one for aosp rom is not even worth to rating...

Is there any rom that has everything working (nfc, wifi etc)

So is there any rom (I think stock based would be my best bet) that has no important bugs? Or should I just flash a custom kernel on a stock firmware?

No there is no such perfect custom rom due to some technical limitations.

Try stable ROMS, there is more probability you find everything working there. I suggest you Resurrection Remix for personalization and CM 12.1 for stability. Btw is your choice, choose the one suits you best.

as you said the stock based is your best bet but for me i use s5 mini rom it has everything working exept NFC because s5 mini does not have that feature

This rom has probably less bugs than the rest http://forum.xda-developers.com/galaxy-s3-neo/development/rom-galaxy-s3-neo-stock-firmware-t2975102

Best is cm11 with sev3n kernel. 6h of screen good camera(cm12 is a joke), radio and everything. No bugs no lags and finally a decent phone. If you want lollipop flavour install cm11 ideal theme from store. It looks the same. After trying almost everything it,s my choice.

Offline chaning work? Battery idle 7 day work? Thank you.
(SORRY BAD MY ENGLISH 50%)

Yes offline charging works and in cm12 also works. Only cm12.1 has that bug. Try kang cm 12.1 after flashing perharps 10 roms is now my favourite . Well i miss cm11 Camera but you can't have everything, i'm a little tired of KitKat and since yesterday we hace a good lollipop ROM with a good tweaked kernel and almost free of bugs.

I am using stock firmware 4.4.2 with xposed and some modifications. It is good and now i am going to try any custom kernel. For me, custom roms are useless especially those CM based.

Cloudy or MM

Im new at this phone and getting it today the d800 i have files already for CM13. Which one is more stable and can overclock without issues? Cloudy or MM?

Why do you want to overclock? CM13 is 100 times faster then any 5.0 stock rom, you don't need to overclock. But when using CM you should accept there are bugs and parts not working well. Camera is always best on stock! Sound in stock is better. But on CM13, GPS works well and my phone is as a brand new up to date fast phone. ALthough there are some bugs, it's stable as hell. Never had any hangup or reboot, using CM13's special build from Dr4xxxx (see the most thanked post in official CM13 thread) and Psychogames Kernel. Battery is the same for me.

It depands on you
Well I have tried both ....cloudy rom gives you the feel of LG g4 plus it is stock based rom so it will be bugs free... but it has a lot LG bloatwares which some people find them useful ..you can also install dorimanx kernel which can overclock both CPU and GPU (which for me it is note an important feature since it affects battery life and stability of our precious g2).
CM13 in the other hand is debloated rom with all new Marshmallow features with fast response and much more free ram...it has a few bugs but the developers all fixing it in a good time...I have installed it since last week from Cyanogenmod official site and tested intensively and the only bugs I have found so far are : the rear notification led is not working and the quality of the camera is fine but not as stock .....everything else is working great including the IR remote functions.
For me I have decided to keep using CM13 ?

before doing anything else, make sure your phone is not refurbished. then proceed. if refurbished it could say d800 but be a ls980. so itll brick.
if you dont care about camera, slow motion, and 4k video. then go CM is faster.
camera in stock is better. but CM or AOSP have some bugs. when i tried them theres was hissing coming from speaker.
if you go th cloudy route, then i recomend
CHELOZTEAM UX4 V4.

icex
cloudy. to me battery isnt good as others and its slower. besides the others are based on newer firmwares cloudy hasnt been updated.
