[LG G2 Mini] kokolo15:
I bought this phone 6-7 months ago and i have been messing around with it since then.Here are my experiences with it.

LOLLIPOP:

Currently i couldnt get Lollipop to work well no matter what tweaks and fixes i did.This includes memory leak fixes,Wakelock fixes and scripts.From all the lollipop roms i found resurection Remix to be the best in terms of functionality.NOTE:the time i used cm12 there was only invaderJohns kernel,so i havent used it with nikita's kernel.

also LTE was a ***** to toggle

STOCK

Battery life and stability with stock rom (kinda tweaked a lot)is unbeatable.I've been using it for the most time of them all and it just cant be beaten(With the help of tweaks from 3c Toolbox(AKA android TUNER)and after i uninstalled some bloatware it needs about 13 hours to lose 1% of its battery when i dont use it.

ALSO IR works,the only donwside i could find in stock rom is high ram usage and high battery usage when using mobile data.

stock touch sensitivity is awful too.

4.4.x

All testing has been done using nikita's v3.1 kernel.

CM11 works well.No memory leaks,no random wakes no bull****.Vibration appears to be working but camera has overexposure issues.WHICH you can fix by replacing this libs files in /system/vendor/lib and change permission to 644 and reboot https://www.dropbox.com/s/3d88k0p12iklgop/camera_fix_libs.zip?dl=0 provided by AntonPanos

Currently im using CPA which works best for me.Everything appears to be working correctly except IR which is something to be expected(havent even tested it though).Also camera works perfectly,video though has exposure issues (using camera that comes with rom)which can be fixed if you change to the same video resolution once you want to start recording.IMO this rom is made for the ones that are looking for superior multitasking and simpleness.Its fast,pretty,and lag free.

I installed mortal kombat X btw and it well.

Other roms i havent yet tried cause i find no reason to.(miui v5 appears to have bugs)(PA 4.6 and pac rom might be worth the try).

Also for anyone that has tried or wants to try the PTT(partition tool table)for d620

Be aware that i was using the TWRP 2.8.6 recovery.

Once i used PTT with OPTIMAL setting i let it do its job,then it reboots(at that point is stucks at lg logo as it should).I reboot it using the harware key and it enters recovery.

IF YOU install a rom right away and try to boot the phone you got it soft bricked.For some reason you cant enter recovery using volume down and power button and phone will get stuck at boot animation.Then the only way i found to get it fixed is entering download mode and flashing stock using lg flash tool 2014.

YOU must first format both cache, data AND SYSTEM(do dalvik too wont hurt) partitions VIA twrp before flashing a rom.

This is just me though so if anyone got any experiences of his own pls share!

:good:

EDITED:forgot to add System and dalvik partitions formatting if you use PTT.Sorry!

IMPORTANT:

using CPA atm and found out that during calls phone's microphone(headset's microphone works fine)transmits a buzzing sound sometimes.Also my voice sounds a lot deeper and kinda poor quality.

EDIT:MANAGED to find what is wrong.I did clean install with just nikitas kernel and play store->all was good till i installed faux controls

Do not install FAUX CONTROLS ON CPA cause its gonna break the mic.I got to find a different way to push more power on my headphones now if anyones knows how plz share.
