[LG G Flex] EverPing:
Everything LGL23

Hi to all the fellow LGL23 users,

Here are some quick updates what worked for me on my LGL23.

I was able to unlock and root my LGL23 device and install a custom recovery..

AS of now I suggest to stay on original KDDI ROM version 4.2.2.

Because from version 4.4.2 you might loose some functionality (Wallet function, TV, NFC, unable to root etc.)

But having said this, the below side (Japanese only) gives some really good tips for the original KDDI version 4.2.2 ROM.

Most helpful site (Japanese only):

How to Root the device

How to increase reliability of LTE connection

How to enable Dolby Sound for Music

How to enable Cinema Sound option for video

Other useful stuff

How to bump up / adjust the resolution

Install NOMone Resolution changer

Use the confirm after 1 minute option to avoid messing up your phone !!

1080x1920@320 dpi is perfectly fine working.

Above that its not reliable anymore and System UI crashes (probably due to RAM shortage)

Rooting Android 4.2.2:

I was able to root my device by usage of g_flex_rootkit.zip. I dont recall the download link, existing links seem dead.

The above g_flex_rootkit.zip package contains special version of Towelroot, Stump and SuperSU.

Downloading Towelroot, Stump and SuperSU separately from Google Play store did NOT work for me

NOTE: Dont update SuperSU via OTA once rooted !!

Installing the recovery rom:

http://lgviet.com/forum/threads/root-recovery-lg-flex-kddi-lgl23.29775/

Search for twrp_lgflexkddi_lgl23_lgviet.zip file

Use the recovery.lok file and flash it as recovery.img

This will give you TWRP 2.8

You can use Flashify for installing the recovery rom.

IORoot

Other recovery.img files e.g from "thecuped" did NOT work.

--- Upgrading LGL23 to Android 4.4.2 ---

I managed to install Android 4.4.2 from D959 T-Mobile (US ?).

http://downloads.codefi.re/playfulgod/LG/G_Flex/D959/ROMs/DFUSE_Stock_KK_rooted.zip

Here are my findings:

The D959 ROM is not so smooth as the Japanese KDI version.

Just no comparison.

Please also note that once the ROM is installed 2 updates will be waiting.

(Bugfix only)

However somewhere on the way you will loose root access to your phone.

I am still trying to root again and then restore my previous version 4.2.2 from KDI as the operation is so much smoother.

I can easily change resolution to 1080x1900 which I cant do with D959 ROM.

>> Unless I update the threat I was unable to root Android 4.4.2. <<

Also I was unable to confirm the following functions with D959 ROM..

- NFC

- Wallet function

- TV
