[T-Mobile LG G2x] linux_user9:
Follow the chronological order of the listed items...

1. Several things to KNOW and DO BEFORE starting:

- this is for Linux (that is your computer OS is Linux based) users ONLY!

- Mac (though UNIX based) and Windows users GO somewhere else!

- this REPLACES your stock recovery w/ clockwork recovery; this is NOT the same as installing rom manager from the market, which won't work on your "unrooted" phone anyway, go ahead try it

- this does NOT root your phone by itself, you need to follow all the directions

- be sure your battery is FULLY CHARGED, even though you'll be removing it for part of the directions

- COPY a rom of your choice to your external sd (ONLY if using ctso's procedure or using the updated clockwork recovery zip file labeled "external," otherwise copy the rom to the internal sd); I recommend CyanogenMod 7.1.0.1 Stable

- follow the procedure listed in #2

2. Procedure for replacing your stock recovery w/ clockwork recovery:

- SEE UPDATE BELOW as this flashes clockwork recovery v3.0.2.4

***********************************************************************************************************************************

The following procedure was provided by xda member ctso...many thanks to him!

***********************************************************************************************************************************

Again, thanks to ctso for the UNIX terminal bash script! Be sure to THANK him yourself!

***********************************************************************************************************************************

UPDATE:

- download one of the attached clockwork recovery zip files (they include nvflash) below INSTEAD of ctso's "nvflash-recovery.tgz" to have the newer clockwork v4.0.1.5

- use the "external" file to have clockwork read files from your external sd card

- OR use the "internal" file to have clockwork read files from your internal sd card

- THANKS to krylon360 for the updated clockwork

3. Several things to DO AFTER your DONE with the procedure by ctso above:

- reboot device into clockwork recovery by holding the POWER button and VOL DOWN button, let go when you see the word "ANDROID" in the mid-left, upper portion of the screen (occurs after the LG logo appears)

****I can't stress the next 4 items in bold red enough BEFORE proceeding to load your new rom****

***If you don't do this, you're a fool***

- be sure to "wipe data/factory reset"

- be sure to "wipe cache partition"

- be sure to go to "mounts and storage" then "format /system" then "format /data" then "format /cache"

- be sure to go to "advanced" and "Wipe Dalvik Cache"

- NOW, you may INSTALL the rom you copied to your sd card in #1

- be patient! You may not get feedback that the rom is loading! Let it sit for ~10min.

- once finished the clockwork recovery menu will reappear

- be sure to go to "advanced" and "Fix Permissions"

- be sure your battery is FULLY CHARGED, go to "advanced" then "Wipe Battery Stats"

- your done; you now have "rooted" and "rom'ed" your device!

_____________________________________________________________________________________________

- I'm NOT responsible if you "BRICK" your phone

- If you don't understand what Linux is, you probably shouldn't be elevating the user privileges by "rooting" a phone that runs the linux kernel

- Do as I say, not as I do

- If I'm coming across as an asshole, it's because I probably am; I'll try to be nicer next time

- Developers put in a lot of their time and talent into projects for us for free, be sure to THANK them and DONATE to them
