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.

Still no e975 support. :(
choose f180k. if status bar is proved compatible everything will be good.
gomdolight kitkat is more script-oriented, so not many apks are replaced from the stock firmware. so there is a quite high possibility that it will be compatible with many variants.

however, you may need to 'debloat' the stock firmware by yourself, since i do not know what bloatwares are preloaded in non-korean stock firmware.

@juniecho thanks for your contribution, i have F300K branding is Olleh, now it is in recovery mode i have downloaded 2 file f20l.kdz and f20f.kdz but all stop at 50% or 54% when flashing, does F300K need to be flashed by its own specific branding? do you have links to these F300K Olleh firmware? (to flash before going to Gomdolight)
i would like to try using this Gomdolight ROM ;)

sorry for late reply. by f300k you mean vu3. in the manual http://gomdolight.com/?page_id=518 you can find the 'firmware compatibility table' at 4-2.1. when you look at the table you will find download links for 20F stock kdz, which is proven safe. f300k can be flashed via lg flash tool 2014 (without specific branding or utility, etc.), and since the kdz file i provide is not a CSE-type kdz, you can just flash it with 'normal flash' mode. (by contrast, CSE-type kdzs should be flashed with 'CSE flash' option, and if you choose 'CSE flash' mode it will force a factory reset upon flashing)

sumup: 1) download the kdz file from the firmware compatibility table in the manual, 2) flash it with 'lg flash tool 2014' with normal flash mode.

did that already but stops at 40 or 50% when flashing, downloading the kdz file with IDM is not a problem? but i think when preparing the kdz file if any error occur, the LG flashtool should have notice it right?

not sure. but for the f300k20f kdz,
CRC32: C766C041
MD5: 0D090EE1200812E11D2B87D2A5376C6B
SHA-1: 8F1CBAA6B1ACAAEB0D18E719B2240EAE5EBECE61
check before flashing.

UPDATE - Wave 2, revision 9

UPDATE LEVEL: MAJOR / IMPORTANCE: CRITICAL

UPGRADE INSTRUCTIONS:
  • Use the clear.root flag to unroot before upgrading if you're rooted (IMPORTANT)
  • You can always re-root using the enable.root flag (SEE http://gomdolight.flags.usage.gomdoli.us for details)
  • You do not need to revert to stock, but choose the 'FRESH INSTALLATION' option at the Installer's main menu even though you're actually upgrading. (You will go through the reconfiguration process)
CHANGELOG:
  • Greatly improved GomdoLight Engine scripts
  • Added support for a new flag: reboot.recovery - reboots into recovery environment (automatically into 2nd-init recovery if installed)
  • Added support for a new flag: auto.install.xposed.framework - automatically schedule installation of Xposed framework when the Xposed Installer app is installed but the Xposed Framework is not.
  • Improved stability and battery efficiency
  • Automatically restores GomdoLight Engine functionality when GomdoLight Engine can't be initialized
  • Removed IM+ from the Update Center
  • Added 'LG Tag+', and 'Privilege Terminal' to the Update Center
  • 'Update Center' components updated
  • (G2, Gpro, Vu3, Gflex) Now the clock/date indicator shown when the status bar is expanded will NOT do anything if you click on it, instead of taking you to the Date/Time Settings screen.
  • (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
  • (G3, G3A, G3cat6) Improved QuickRemote (Q Remote), now you can control some air conditioners and audio systems.

Wanted to thank you for the hard work
Using a LG vu3- K and this was a savior for me - Wanted to know if possible to update the ROM and retrain the firmware? or if there are compatible rom's ? KK 4.2 is still great but newer architecture would be nice :)
