It says 5.0.2.7 because you didn't install it, AT ALL.

Reread the post, its really not that hard.

Yeah, someone a few posts back did it on XP, 7, and 8 no problems.

Here you go, post was literally a PAGE back. Put a little more effort next time.
[T-Mobile LG G2x] jim.k.yee:
That does not work on Windows 8, you get the same error as using the other versions.... It's the "third-party INF does not contain digital signature information" error that we get when we try to install the APX drivers
[T-Mobile LG G2x] theking_13:
Then how did mustangtim49 confirm it working? :eek:
[T-Mobile LG G2x] KiNG OMaR:
I've added the instructions to flash the touch recovery to the OP, with a nice little warning. Guys, don't use this unless you know how to fix it.

Also, Windows 8 is beta software in itself, I wouldn't trust this to work on it anyways.

This is if you already have all the files and drivers set up:

How to flash ClockworkMod Recovery 5.8.1.3:

CWM Touch is still experimental. Flash at your own risk. Do not expect much help if something goes wrong or does not work right, be prepared for some crisis management. Not everything works properly, but when it does work, it works pretty well. This has bugs. Do NOT flash this unless you know how to flash an alternate recovery if things go wrong.​

download the 5.8.1.3 clockworkmod *TOUCH* recovery image

place p999-5.8.1.3.img in C:\G2x\NVFlash

Unplug everything

remove the battery

Hold Vol Up/Down (and keep them held)

Insert USB cable

open command prompt

execute the following commands:

cd \
cd g2x\nvflash
nvflash.exe --bct E1108_Hynix_512MB_H8TBR00U0MLR-0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 5 p999-5.8.1.3.img
[T-Mobile LG G2x] Bowmanspeer:
I wanted to say thanks. Button hit. Also worth noting that I was not successful the first attempt. I didn't create the files correctly, or rather I did create the files but without the proper contents. Anyway, 3rd time was the charm and I now have Touch ClockworkMod.

I also find it necessary to reboot computer sometimes to get apx driver to properly install.
[T-Mobile LG G2x] Alakratt:
Ok, I'm still kinda on the fence about the touch version, still, glad it's been ported. Anyway, here are two my questions:

-Has CWM 5.0.2.7 been completely tested for the G2x, all the features working, etc?

-What are the changes from 5.0.2.0 to 5.0.2.7?
[T-Mobile LG G2x] sheck:
Used this method. Confirmed working on Windows XP.
[T-Mobile LG G2x] rosevilletoyota:
Confirmed Working

I ran the touch version and tried to install Singh version of MIUI and will not boot stays on LG Logo. Then I uninstalled it and install the standard recovery and BINGO it works. As for ICS ROMS it has no issues works fine.:p:p:p
[T-Mobile LG G2x] Alakratt:
Could it have been a bad rom download?
[T-Mobile LG G2x] millowster07:
I had the same issue when I tried flashing the 21y rooted update. It would boot loop, but when I flashed stock 21v it worked. Not sure why. It also hanged a bit on the install. But again did not hang on the 21v rom. Seemed very picky with its roms.
[T-Mobile LG G2x] stevew84:
getting an error in CMD saying "cannot determine external or external command while trying to flash the .img
[T-Mobile LG G2x] LurkerRWO:
Loving the touch CWM, very nice work. One problem I have with it though is that it cuts off file names that are too long. I have like 6 versions of owains rom still on my sd card and just guessed that the latest would be at the bottom. I guess I should just clean up my downloads folder but any chance we could get a way to see the full file name? A scrolling effect on highlighted options would be nice but honestly any fix would be adequate.

Thanks again for the instructions!
[T-Mobile LG G2x] theking_13:
You could just rename them as such "Owain vX.X" and that way its a lot shorter.

Im having flash issues on this

I type this in the command box and i get it to flash but it comes back saying its starting but it says --b1 is an unknown command am i doing something wrong

cd \

cd g2x\nvflash

nvflash.exe --bct E1108_Hynix_512MB_H8TBR00U0MLR-0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 5 recovery-clockwork-5.0.2.0-p999.img
[T-Mobile LG G2x] jaywillsoul:
something I've learned. You can skip the change directory (cd) and just drag an drop the files. so it should look something like: C:\(user and directory)/>--bct (bct file) --bl (Boot loader file) --download 5 (CWM boot image)

when you drag and drop it adjustst the directory command for you.
[T-Mobile LG G2x] cricketAC:
Because it's bl not b1.
[T-Mobile LG G2x] Whyzor:
Just a suggestion, you could create a flash.bat file and have it include the first part of the long command line since it's consistently the same for different recoveries on the G2x, only the last .img parameter is different for different CWM versions. So the user would just have to type something like 'flash.bat cwm5.0.2.8.img' That way there's less chance of messing things up for the user.

Also should probably add 5.0.2.8 up there too in OP.
[T-Mobile LG G2x] mustangtim49:
I don't know what you're doing wrong, but I updated both my phones with windows 8 and had re-flash both my phones with 5.8.1.3 on windows 8. So no, you're wrong, it does work on windows 8.

mustangtim49@xda-developers.com
[T-Mobile LG G2x] KiNG OMaR:
Here's a newer method to update the recovery. It's an all-in-one package (if you have the drivers installed) :o

This will flash the 5.8.1.3 touch based recovery for you:

Download NVFlash5813.zip

Unzip and run this script "G2x NVFlasher for Dummies 5813.bat"

Please tell me how it goes, I really don't have an LG phone to test this on so I'm relying on feedback from you to make this recovery flashing an easier job!
[T-Mobile LG G2x] karlnorth:

[T-Mobile LG G2x] noahk423:
It didn't work because the O2x has different partitions than the G2x. So, this is not something you would use for your phone. But you did, but hopefully you can get it working again.

It'll definitely work, has nothing to do with the ROM your running.

Did you download the file that I provided or did you have one from before? Because the one I provided is:

E1108_Hynix_512MB_H8TBR00U0MLR-0DM_300MHz_final_emmc_x8.bct

[T-Mobile LG G2x] crazythunder:
it could be buried in a folder on an external hdd. it doesn't matter. root of c drive just makes it easier for most people to navigate to. as stated above, simply right click an empty area inside your nvflash folder and select "open command window here"
[T-Mobile LG G2x] crazythunder:
get the nvflash with no extension out of that folder. owe me a coffee

someone else did that, the minute i told them to take it out, it worked. just a suggestion.

go to your clockwork folder on your internal sdcard and copy 3.0.2.7 to your pc. then flash it.

[T-Mobile LG G2x] sryan1983:
You can flash the 3.0.2.7 recovery instead if you want.

http://mirrorbrain.cyanogenmod.com/cm/recoveries/recovery-clockwork-3.0.2.7-p999.img

I had to rename the file as the command prompt didn't like all of the periods and dashes in the file. I just renamed it recovery.img and flashed it that way. Just make sure you adjust the nvflash code to reflect the new file name.
