[stock firmware][D80020c] recovery friendly D80020c
This is for D800 (AT&T LG G2) users ONLY.
This package will update a phone with D80010d firmware to a "mixed" firmware that boots normally to D80020c (kitkat), but retains the older boot loader and compatibility with loki patched custom recoveries. The "normal" boot is 100% unmodified stock.
This "mixed" firmware is currently the only known way for a stock D80020c (kitkat) system that also allows custom recovery.
- rpm, tz, modem, and system partitions from the stock D80020c (kitkat) LG G2 firmware.
- LG's D80020c kernel, recompiled by @Savoca, and made compatible with the D80010d bootloader.
That will leave your existing D80010d boot loader (aboot) intact, as well as whatever custom recovery already installed.
This firmware package will (or at least should) refuse to install on ANY firmware other than the D80010d firmware. Please don't reply to this thread if you are using anything else. (That was as polite as I'll be on that issue...
suggest doing a full wipe on your device after flashing this. You don't have to, but it'd be a really good idea...
This is NOT my software. This is 100% LG's software and firmware. Don't ask for support in this thread. It won't be provided.
- Restore your phone to the stock LG G2 D80010d firmware. Please click "here" for directions. (remember that you have the AT&T device when reading that post...) If you don't like that post, here's a youtube video (not mine) for doing the same thing. Make sure you restore the D80010d firmware and _not_ the D80010o firmware!!
- Root the device and install recovery (recovery is required, root is not.) This is a link for rooting instructions. While you are welcome to use CWM for your recovery, this is a link for installing TWRP recovery. (Since cyanogenMod took freely given contributions to their codebasse and went private/for-profit, I have a personal bias against them - so my personal recommendation is for TWRP.)
- Copy the d80010d_to_20c.zip package linked below to your phone.
- Reboot into recovery and install the d800_to_20c.zip package.
- Optionally, also install a superSU or other root package.
- Optionally, but suggested, Perform a "factory reset" on your device.
The main package (about 1.7GB): Dev-Host
SuperSU: Direct from Chainfire's webpage
Several people spent countless hours working on finding a way to get recovery working with LG's kitkat. The kernel used in this package was made by @Savoca
- who used the solution found by @JackpotClavin
. Others involved are (as far as I'm aware) @AndroidUser00110001
. Of course, @Chainfire
for the 'su' package.
All the images in the recovery package are completely stock with the exception of the kernel and kernel modules. The kernel is modified and recompiled with only the following patch: https://github.com/JackpotClavin/and...5b863baa8d1064
. (The installer overwrites the kernel images in /system with those from the kernel compile.) The base kernel source is found on LG's opensource website under the D800 heading.
May 2014 Update:
I'm no longer able to tinker with my G2. My wife took it from me (for her own use), and she gets angry when I mess up all her settings.
(I ended up getting a HTC One M8 to tinker with.)
While I'll leave the thread unlocked so users can assist each other, please don't expect prompt responses from me or maintenance.
