I have the LG G3 D855 International Model, purchased from PB Tech a few weeks ago. So, being an Android user who likes to modify my phone my first response was to look into any custom roms, rooting etc. Unfortunately, being a new model of phone and possibly not as popular as Samsung there is little out there at the moment.
Here is what I have done:
- Used stumproot to brute force the root.
- Super SU to allow root access permissions
- Titanium Backup (haven't backed up yet) I used this to delete a couple of system apps.
- Installed LG G3 TweaksBox from the playstore and bought the unlocked version. It's really straight forward and I have since disabled battery full notifications, skinned the pull done menu, set call log to default phone display and a few more.
- Increased volumes on speaker, headphone and aux following this http://forum.xda-developers.com/lg-g3/general/guide-headphone-speaker-volume-booster-t2819821
- Used trickstermod to set governors as desired.
- Additional apps I have used Root File Manager, Xposed Installer, busybox on rails, 920 text editor, root checker.
- Enabled all apps on dual window. Find the tutorial at lgg3root.com
- I don't think there is a working version for TWRP or CWM for this model yet. So be careful.
- Phone can be unbricked if any problems occur (lgg3root.com) but I had no problems so assume you probably won't either.
While I am no expert and actually usually bumble my way through mods I thought it'd give some idea about things to do.
As for the network I am with 2 Degrees on prepay bundle (Auckland). I knew that the phone should be 4g/LTE compatible but there was no option to select this in network settings - this confused me. 2 Degrees customer service wasn't able to offer any ideas but according to their 4g coverage map I should be receiving 4g.
So there is a hidden menu - access it by dialling 3845#*855# Go to LTE Only, Modem Settings, RAT Selection, and select the one you want there. I selected auto and it seems to default to 4G now.
While I am not intending to do any 'How to' posts thought that maybe some geeks out there would find this useful.
