[CFW][KK4.4] GomdoLight KitKat Custom Firmware Environment (System Enhancement Pack)

[juniecho]

Hi all,

Today, I proudly present GomdoLight KitKat for KOREAN LG G / G2 / G3 / G3A / G3cat6 / Gflex / GK / Gpro / Gpro2 / LTE3 / Vu2 / Vu3 / Gpad7LTE, one of the most widely used (with 20,000+ users approximately) stock-based custom firmware in South Korea.

GomdoLight is more than 3 year old already (first version released on 19th December 2012), and is very mature.

Technically speaking GomdoLight is NOT a complete ROM, but rather a large-scale patch, which modifies official stock firmware to remove all the unnecessary components preloaded by operator/manufacturer, and reorganizes key system parts to 'basic' Android OS with manufacturer's flavor. For some devices GomdoLight's own specialized tool 'GomdoLight Sideloader' can make it possible to install GomdoLight directly over the stock firmware, even without rooting or flashing custom recovery!

GomdoLight is compatible with the following devices (BOLD indicates GomdoLight Sideloader support - no root required)

• LG Optimus G: LG-F180S, LG-F180K, LG-F180L ("G")
• LG G2: LG-F320S, LG-F320K, LG-F320L ("G2")
• LG G3: LG-F400S, LG-F400K, LG-F400L ("G3")
• LG G3A: LG-F410S ("G3A")
• LG G3 Cat.6: LG-F460S, LG-F460K, LG-F460L ("G3")
• LG G Flex: LG-F340S, LG-F340K, LG-F340L ("Gflex")
• LG GK: LG-F220K ("GK")
• LG G Pro: LG-F240S, LG-F240K, LG-F240L ("Gpro")
• LG G Pro 2: LG-F350S, LG-F350K, LG-F350L ("Gpro2")
• LG Gx: LG-F310L, LG-F310LR ("Gx")
• LG Optimus LTE3: LG-F260S ("LTE3")
• LG Optimus Vu2: LG-F200S, LG-F200K, LG-F200L ("Vu2")
• LG Vu 3: LG-F300S, LG-F300K, LG-F300L ("Vu3")
• LG G Pad 7.0 LTE: LG-V410 ("Gpad7LTE")

A very thorough and extensive (probably, the most extensive on entire xda) manual is provided at the download page, which contains literally everything you need to know to install GomdoLight. FAILURE TO READ THIS DOCUMENT BEFORE INSTALLING WILL ALWAYS LEAD TO VARIOUS UNEXPECTED PROBLEMS. PLEASE READ CAREFULLY. Needless to say, I WILL NOT ANSWER ANY QUESTIONS ALREADY ADDRESSED IN THIS DOCUMENT.

Due to xda forum's limits (in functionality) I am posting a link to the separate (external) DOWNLOAD PAGE. There is no way I can link to each section in the document in xda posts, since xda does not support HTML tag. However some portions of the document are also introduced here.

What's the difference between this rom and other Stock roms in the forum? Genuinely questioning, not flaming.

What's the difference between this rom and other Stock roms in the forum? Genuinely questioning, not flaming.

They are stock-based ROMs that reinstalls the OS. This one is a large-scale patch that modifies the exiting stock firmware, and add some very unique features. It has a very extensive startup script set made my me, and the script set gives GomdoLight unparalleled flexibility and disaster recovery capabilities.
GomdoLight does not focus on hacks and tweaks, but rather on usability and stability.

Can be ported to other variants?

Just for F320, guys.

It sounds good! I will try it and give you a feedback later! Thanks for the answer.

Hold on your horses, first of all this is not a ROM as stated and I guess you own the D803 variant once you're on Canada, I wouldn't try it once it plays around with the system partitions and those are quite different between Korean and worldwide variants. IDK much about these scripts for the KK stock but I definitely would not try it.

If they're just a bunch of scripts they could be Open Source for contribution, couldn't they? It would also be better for contribution and porting to other variants although I think we rarely have people here that use the pure stock KK once we have a lot of custom AOSP and good LG based L/KK ROMs.

1. partition layout is usually not important with gomdolight.
2. it is not just a bunch of scripts. as of now, the script set EXPECTS the full gomdolight system installed and it is specialized only for gomdolight. however anyone is welcome to port the script set to other devices.

gomdolight is developed to unleash the true potential of pure stock KK, and prove that stock KK can be indeed useful without system tweaks or such apps if aided by just some specialized scripts.

you could try this on your variant, trying each of officially supported variants (SKTelecom,KT, LGU+). most of the time at least one works.

• You can always re-root using the enable.root flag (SEE http://gomdolight.flags.usage.gomdoli.us for details)

• (G2, Gpro2, G3, G3A, G3cat6, Gflex) Now you can choose between stock navbar thickness and reduced (by about 25%) navbar thickness
• (Gpro2, G3, G3cat6, Gflex) Better DualWindow (SplitWindow) app support
