[G4 General] karmacoma7:
This thread purpose is to collect all up-to-date data and files on LG G4 Korean Versions

I personally own a F500l version which is form U+ carrier (unlocked)

Since I bricked the phone once, and successfully recovered it, I decided to share the info I have.

Hardware wise the phone is similar to 815, but modem firmware is different, country specific stuff,etc

Custom recovery

Boot is locked, no custom recovery. Tried flashing with flashfire, no luck

Lgviet.com has video twrp working f500l but no downloads

F500L Latest 5.1 ROM 11i ROOT

rooted system + tools (courtesy of lgviet.com)

11i rooted

If you are on lower system - upgrade with OTA until you reach 11i

after that download easy root tool

rename 11i rooted system image to rootedsystem.img and place it to phone`s internal memory

Launch easy root tool and follow instructions

Latest 6.0 ROM 20d root info

Available form LG Bridge

No root for now, our bootloader is locked, means no kernel modifications, means no root

since MM requires kernel mods for root.

My experience with 6.0 doze is nice, but I get same idle battery drain with Amplify+power nap

Wil post my settings later

Lgviet.com bootloader unlock for f500l is not available for now (I even registered there, but website has everything but download link :) )

You can convert your phone to 815 by following guide here by redhatux

Below is my experience with conversion.

I did, however was not able to get f500l back as a phone model, and the reception was not flawless, also after you change it in this way, keep in mind, that to get back to stock you have to edit build.prop (which in my case was not possible to do, since phone boot looped after I flashed Genesys rom with Flashfire) My fault, of course :)

So I got a soft brick in this way, went to LG service center, they had restored 11i rom for free never asking if I played with customs etc ( Korean service rox, thanks guys)

Although now,I think, that probably I would have been able to restore on my own, since LG BRIDGE for win was detecting phone and was ready to flash 20d, but I couldn't (because of usb connection issues (Long story short: I use Win 8 under parallel tools under osx, got too much drivers from different phones. recently cleaned it, everything works)) My opinion is before you flash a rom from 815, you better make backup of all partitions that are rewritten and you will restore from your own phone, and not use redhatus backups ( he provides it on his thread). perhaps thats why I did not get the reception back( Flashed& restored backup more than 3 times)

Conclusion: proceed with extreme caution.

I will see if rooted 11i stock has a decent battery life, and it should, since there is an option to switch off wdcma,lte and gsm frequencies ( see my battery post below) which 815 roms are lacking.

To downgrade to Lollipop use full stock tot file for f500l 5.1 ver 11d

flash with LGUP

Battery life, ok with mods some info below:

I am able to get 4.5 hours SOT, under heavy use

1 hour of 720p video, 1 hour of skype,40 mins of viber (video calls) ,30 min of web browsing.

a little gaming.

Al of this with with radio frequencies disabled, cpu&gpu frequencies lowered, xposed+ amplify.

otherwise 2.5 SOT

On 11i stock (probably on older roms) you can make battery life better by disabling the unused frequencies.

Enter 5457#*500# in your dialer

select Multi band Selection, then

Check the wcdma and lte frequencies used in your country and uncheck that you don't use.

Since I am in Korea now, I use WCDMA2100

For Russia, for instance, its gonna be WCDMA2100 and WCDMA900

With kernel auditor, I changed BIG max frequency to 1248 mhz,

governor to ondemand, governor tunables Powersave_bias 1

Little MAX Frequency to 960

governor ondemand ( same settings)

IO Scheduler: noop

GPU max frequency: 600

Also I installed Snapdragon battery guru, limiting app sync to only when I use it.

What I have got afterwards: solid 6 hours of SCREEN TIME under heavy use!

Pcmark battery test lasted 6 hours with 3g + wifi data.

( I seriously don`t understand how guys [MENTION=2480563]anandtech[/MENTION] managed to get 6.6 hours in pcmark battery test on complete stock?! )

Great tips for battery life
