[T-Mobile LG G2x] kosh2thamax:
This is what worked for my phone....i'm not responsible from what happens to your phone your responsible for your own action...DO THIS AT YOUR OWN RISK! THIS METHOD doesn't require XP :D

OK so your phone is bricked because of the update by lg and your are stuck at the s/w screen...and The other method of flashing the KDZ file and program keeps freezing and not working even on XP ...if you haven't tried that method first you should its much easier and faster if you have and it's FAILED then hopefully this will help.

EASIEST FIX!!! This is for KDZ just encase you havn't tired this first my method is below....

Credit to bullseye69....THIS WORKs FOR WIN 7 ....so i guess you could try vista...but i'm not sure.

READ FIRST!!!!

FOR BULLSeye69 his phone was working SO he used DIAG MODE BUTTT

IF your at s/w screen OR HAVE NO BASEBAND and NO BATTERY and NO IMEI...DO everything the same EXCEPT!!!! change DIAG to CS_emergency AND IT WILL WORK...give it a couple tries ....if it doesn't work first 2 - 3 times it's ok go to task manager and Right CLICK on the LGUPDATE tool in the process list and change set priority to HIGH and it should go through. HOPEFULLY THIS FIXS IT :D GOOD LUCK G2x owners

OTHER METHOD : ONLY use this IF KDZ methods did not WORK (again at ur own risk)

hopefully this method will help you....(tried to be noob friendly as possible) READ THE WHOLE AT Thing LEAST ONCE

(PS download all those files they tell you to download because you will need them and i take no credit for those programs and files just this method on how i used them)

OK my phone condition was (2.2) s/w update screen....and was able to boot into cwm(clockwork recovery but not stock) using the ONE CLICK RECOVERY (internal sd flash)

So on stock 2.2 stuck on s/w update screen

my first mission is to just get past the s/w screen since i tried flashing a nandroid backup which i downloaded and it didn't work. (ps download the nandroid file "LG-P999-V10f.rar" credit to the dude who uploaded it )

Extract it using winrar or whatever program.

Now once you have the nandroid file you should see one md5 file and 6 .img files like recovery, system, etc....

so we gotta flash each one at a time....pain in the *** but if it works you'll thank me

OK so i was thinking like this kdz flash thing didn't work for me so i want to do everything manually ...alot of work but i have a 500$ paper weight...tough to figure the language but give it a little time.

LIST OF WHAT YOU NEED

One click recovery

Drivers installed

Nandroid file

so (assuming you have all the programs downloaded and installed) take all the img files (not the md5 one) and paste them into the nvflash folder of

the one click recovery folder.

Now open command prompt (type in search cmd)

we will used Command prompt next take battery out and press and hold up AND down volume buttons together and plug in your phone

(Apx driver should be recongized if drivers are installed)

Command i found to use (again credit to who made the command)

normally command promt (cmd) it starts with "c:\user\user"

so change this to where you saved the oneclick file...(easier to save the one click and other file right on c drive not into other folders)

For example my file is save in C:\oneclick\nvflash

SO this means i saved the file in c drive, and i need acess to "nvflash" folder inside "one click" since the nvflash program is in that

folder...

So change the location to where you want to access type in

cd C:\oneclick\nvflash (this is my file location obviously)

command language

nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 8 .android_secure.img

NOW UNDERSTAND THE LINE SO YOU CAN FIGURED IT OUT EASIER...i'll try to be noob friendly as possible

"nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --"

this line for you noobs out there (not trying to insult lol) is just copy paste ok BUT

the second part ""download 8 .android_secure.img""" download is standard so that's also copy that

but SEE the 8 that number is the partion number ...bascially divsions on a harddrive so the 6 img (image)

file goes in their own number...so i'll post where .img file went in which partition but you may have to play

with the number to find ur phone's particular number...i'll explain futher

SO partiton number 8 is where my android_secure.img flashed and went throught without an error

so now i'll post the command for each img file that worked for me hopefully works for your G2x

(REMEMBER!!! after each command goes through the phone will turn on to the S/w screen , Once it says SUCCESSFUL (on CMD) unplug and plug back in hold the 2 volume keys)

for the android secure img file:

nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 8 .android_secure.img

for the cache img file:

nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 9 cache.img

for the boot img file:

nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 11 boot.img

for the system img file:

nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 7 system.img

for the data img file:

nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 15 data.img

~**NOTE IT IS BROUGHT TO MY ATTENTION THAT its possible that by COPYING PASTING ADDITIONAL SPACES MAY have been enter into the line so double check there are no extra spacing because then the command line becomes useless and doesn't work~****

NOW if they show an error like NV 120000 000 or something like partition error... then the NUmbers of your partition of where

these files go are different on your phone So it's not the END OF THE WORLD just play around with the numbers they are usually

very close so if number 15 doesn't work for the data.img then try 13, 14 or 16 they should be just one or two numbers away from

mine. (sometimes if says nvflash started and nothing happens you just have to unplug and plug again holding the 2 buttons)

Trial and error is how i obtained these numbers.

once all these files are sucessful goes through do a test but putting in your battery and going into recovery or just try booting (you not suppose to be plugged in for this)

it normally if it shows LG logo and goes to another LG logo with a LOading bar at the bottom wait for it may reboot,

IF it doesn't reboot it's OK because (after the normal boot) the S/w screen doesn't show up you have SUCCESS because the nandroid file SHOULD

work.

(IF your S/w screen has not gone away YOU Might HAVE TO wipe everything using CWM(Recovery holding power and down) and i mean everything format everything for every option that

(you get in CWM (recovery) go through what i did ....but THAT's only if you cannot get rid of the s/w screen )

(and then try again from the begining REMEMBER WIPING = LOSS in BASEBAND aka calling connectivity so through CWM make a backup of your file and save to your computer you may need later)

OK so we don't need cmd (command pompt) anymore you got your s/w screen to go away.

Now use NVflash and click the "one click recovery" button

(plug in the phone again (no battery) holding 2 volume buttons) and flash CWM to INTERNAL SD (not external)

IT's the first Button on the left (you should see 3 buttons to click on )

once it goes successful you can close the window and unplug.

pop in battery reboot holding POWER AND DOWN VOLUME KEY ...KEEP HOLDING till you see ANDROID RECOVERY (has like pictures of apps falling or something)

then the menu should pop open go to the mounts and storage and then all the way at the bottom (use volume keys to go up and down) mount usb storage option

and (make sure usb plugged in now) hit power button to open STAYY!! in that menu to acess the Storage on the phone...don't exit or hit unmount

nothing will happen if you do by accient exit...just it's easier to explain this way lol

now you should see on the PC (in my computer or automatically open the drive storage for your phone) in there you should see your folders and one of them is clockworkmod

in that there should a folder called "backup" if not make one, all small letters "backup" in there copy the whole LG-p999-v10f file you extracted into the backup folder.

now on the phone (once it transfered the file) hit unmount or hit go back using power button and go back to the first menu

above the mounts and storage option there should be the "backup and restore" option ...open that and hit the restore option and

you should see the LG-p999-v10 file there and hit power on that and go down to yes option and hit open and let it run should take roughly 5 mins.

let it go till it comes to the menu again... now hit reboot system...phone should turn off...if it doesn't turn on within 2-3 mins you can turn it on

your self and android should up and running :D YAY!!!!

(This is for only people who did a full format when they couldn't get rid of the S/W screen)

Now i have had some battery/signal issues....Thats because i did the full wipe of everything some people may or may not have this same problem hopefully someone can post a radio file zip or something ....cyogenmod is another option but i haven't tested it yet

will post result of the battery issue later

EDIT:I have put cyanogen mod (credit to cyanogen mod guy lol) on and seemed to fix the battery reading issue.

EDIT:

IF NO BASEBAND AND NO BATTERY TRY METHOD 1 again at top of the page

KDZ in CS_emergency mode ...and if on windows 7 setup the KDz as in the link above (bulleye69) then proceed to flashing it in CS_emergency mode

HOPEFULLY THIS HELPS ALL THE REST G2x semi-bricked owners....DON"T FORGET TO HIT THE THANKS BUTTON!!!!! :D
