[G2 Android Development] grinch247:
ALTERNATE INSTALL METHOD (

No RSA Fingerprint message

)

1) Get a terminal emulator.

2) Get a file explorer (like Root Explorer).

3) Get a RAR app for android.

NOTE: The RAR app is not needed if you are using your desktop PC (and you have 7zip or WinRAR or equivalent) and you move the files to your SD card.

3) Extract the contents of the file you downloaded and put the "g2_security" and "recovery.lok" files here: /sdcard/

4) Open the terminal emulator and type "su" then hit the enter button. (If this doesn't work, then you are not rooted).

5) Then type:

"dd if=/sdcard/recovery.lok of=/dev/block/platform/msm_sdcc.1/by-name/recovery"

6) Then type:

"rm /sdcard/g2_security"

7) Reboot your phone and enter CWM!

HOW TO ENTER RECOVERY

Method 1: Hold the power button + volume down button until the LG image appears. Once it does let go of the buttons then immediately push and hold them again until recovery boots.

NOTE: The method above will arrive at the "hard reset" area, but when choosing hard reset, it will take you to CWM (without actually resetting).

Method 2: Download the free app "Rebooter" from Google Play. If you have root, you will be able to select to reboot into recovery (among other options).

WIPE CACHE FIX - UNOFFICAL (

RECOMMENDED

)

If you flash the unofficial CWM version, the cache wipe will take only 1-2 seconds!!!

WIPE CACHE FIX - OFFICAL

The data wipe is incredibly fast, but the cache wipe is incredibly slow.

This fix won't match the speeds of TWRP's fix

, but it will greatly speed up the process. This should

only be done when switching to another ROM

.

1) Boot into CWM.

2) Click on "mounts and storage".

3) Click on "format /system".

4) Click "Yes - Format".

Now when you perform a Factory Reset it should only take about 1-3 minutes (stock ROMs seem to take longer) instead of 5-10 minutes.

NOTE I: It may be optimal to re-perform this method after so many ROM changes, or after restoring to a stock ROM. I do not have enough evidence to support this.

NOTE II: I tested this method using the same custom ROM. Because there was no cache build-up from being a new ROM, I also tested this after restoring a backup of my stock ROM (that had a massive amount of apps and cache build-up).

USB-OTG

A USB-OTG device will be recognized as an external USB device while in the Android OS. However, when in CWM recovery, the

"mount USB storage" in "mounts and storage" does not work. Instead, use "mount/ external-sd". This only works on the

unofficial versions

.

MISC.

There is an "issue" with the date and time (1970). You can manually change a Backup folder name by connecting to the PC or using a file explorer.
