How can I revert my phone to stock? - T-Mobile LG G2x

I am running an early CM9 build on my phone (the original SelfKang1 ROM) and I'd like to simply revert my phone to the stock LG gingerbread. I don't mind if CWM stays (it was nvflashed), but I do want to be able to update to V21Y and get the new baseband.
Can anybody help me out, how do I do this?

Guess you didn't make a nandroid of the stock rom? You can download one here and restore it then update your phone with the lg tool to get the new baseband

Thank you! Where can I get a copy of the LG tool by chance?

http://www.lg.com/us/mobile-phones/G2X-Driver/index.jsp

Hmm... I'm having a problem. I downloaded LG-P999-V21e.zip and I put it on the internal memory, and when I try to flash it with CWM, it says Opening update package, them immediately says "installation aborted" with no further explanation.
What is going on??
EDIT:
Going to try again on external SD, missed that part...

All right, what's the deal here?? I tried flashing it from the external SD now and it keeps saying installation aborted! Why??

I've never used that guide but from sifting through it I believe you need to extract the zip you downloaded so its just one folder then move it to your CWM backup folder on your SD Card and restore it in the backup/restore menu. It's not a ROM that you flash its a backup (nandroid) of the stock ROMS that you restore

I just noticed that as well, trying it now, thanks!

Uhggggg it's saying MD5 error and there are NO spaces in my directory names.... :/
OMG! I tried with a different SDcard in case mine is corrupt and same md5 error!!

The download could be corrupt but I read someone say try renaming the backup to something like A and see if it fixes it

You mean the zip file to A.zip??

No whatever the folder was called when you unzipped it

I'm an idiot... I just put the zip file on the SD card... fixed it now.
Man this is different in every way from the normal flashing procedure which threw me off...

Flashing roms question....

coming from a G2, i have flashed a many a roms, did wipes, etc. my question is not toally newbish, but is newbish to the G2x.
i did the nvflash, installed the newer CWM, comfirmed that i have a recovery setup,etc...
now, from this point is anything different compared to doing it on the G2? i still scroll down to install update from SD card and stuff like that, and install the zip file and phone does all the work?

Yes, should be the same as any other phone with CWM. As long as the flashable .zip is made for CWM and your phone, you're good to go

Hey guys I'm coming from Windows mobile and I've never used CWM before. I rooted, installed CWM using Gunman's directions last night, and I downloaded CM7 to my extSD but I just don't know exactly what to do next. Is there a link someone could provide me or give me directions on the steps I need to take after I'm loaded into recovery?
Do I just wipe and then install zip from the folder? Thanks for the help. Sorry for being a newb.

So once you have recovery, you can now flash custom roms, kernals and themes.
1. Put the files you've downloaded into you ext SD
2. Reboot into recovery by pressing and holding power + vol down button til you see a red recovery screen
3. MAKE A NANDROID BACKUP
4. Wipe data/cache
5. Install .zip
6. Choose the ROM that you want to flash
7. Reboot
Edit: Also if you'd like to save your apps and their data, I suggest installing Titanium backup and make backups for your apps before you flash anything. And if all else fails, just reboot back to recovery and restore your nandroid backup
Somewhere I must have done something different, when I boot into CWM thru the button method I get the red recovery but it doesn't see my backups. When I use Rom Manager, and boot into recovery I get the orange/yellow recovery and it shows my backups. What I need to do to fix so the red recovery sees my backups?

Thanks a lot for the step-by-step list. For some reason when I navigate my folders in CWM the .zip files are not showing up. For CM7, then only file that it will allow me to install is the boot_animation.zip, which I'm sure won't boot the actual CM7 software. Oy ve. I'll keep messing around with it and see what I can figure out. Maybe I'll load a few other roms and see if those .zip files will show up when I navigate the folders.
Has anybody had this problem? Loading the boot.img file to a particular area on your ext_sd card (which was the one I set up when I installed CWM and nvidia or whatever it's called), and then once you try to find it it doesn't show up? Ugh. I'll try at it some more tonight and let you guys know what I find out.
I don't have to rename the boot.img file to update.sd.zip or anything do I? I should just be able to navigate to the folder and install the file, right?

You don't want to unpack the .zip file. The way you downloaded it should be the way you put it on your SD card. Do not rename anything inside the .zip.
So, take the cm7.zip file that you installed, whatever the exact name of it is, and copy that to your external sd card. When you're in recovery, pick the option to chose .zip from sd card, navigate to the .zip you just placed on the card, and it should ask you to install it.
I hope that helps. Let me know if you're confused about anything
If I were to flash cm7 is the newer red text bootloader OK to use?

Alright, I think I got it. On my old HD2 I used to have to unzip the deal when I would run it from my sd card. I think that's where I was confused. So I just download the .zip file, don't extract it at all, place it in the folder, and just run it straight from my phone. Thanks for your help. Hopefully now it will work.
EDIT: That worked. Thanks knuckelpuc. Woohoo, CM7 how I've missed you.

[Q] Restoring back to Stock ROM? Problem?

Okay, so im returning back to Stock ROM for G2X because CyanogenMods version is horrible at the moment (too many glitches and freezes!)
I put the Stock ROM (titled LG-P999-V10.rar) back into the recovery folder of ClockworkMod folder.
It DOES appear on my SDCard that i have it but when i go into recovery, it does not show.
Why is this?
Move it to the backup folder and see if that works...

Hey thanks for snapping at the one person who was trying to help you. I understand you are frustrated, but come on... the OP says you put in the recovery folder. I was clarifying that it should be in the "backup" folder.
Also, didn't you do a nandroid backup before cm7 like everyone suggests?
Sent from my butt using XDA Premium App
Taking a wild stab here, but did you un-rar LG-P999-V10.rar and place the contents within your cwm backup directory on your sdcard?
Sounds like you just dropped the .rar file onto your sdcard -- it doesn't work that way.

It should be in the external sd card , it should be un rared and unzipped into /clockworkmod/backup folder .

1. As far as I know, recovery only recognizes .zip files NOT .rar
2. Not familiar with CM7 so I suggest after converting to zip file, try putting the zip file in BOTH (SD Card & Internal Memory)
Hope this helps.

I had to unzip if and place the folder in the restore folder under cwr. To restore use the restore option under recovery, not the install from zip

So none of your back ups are recognized? Sounds like something went wonky in your recovery. Here is what I would try, but I am not an expert. Redownload the stock rom(probally from TGA's post) to your computer, unrar it to a folder named whatever, p999-stock, mount your phone or pull the SD card and use a card reader and place that folder in the "backup" folder of clockwork mod. Reboot into recovery and see if that works.
Failing that, reinstall cwr...
If no go... do a clean reinstall of cm7... wipe everything, install, I wipe cache again because I am ocd, fix permissions. Reboot, set up, load apps and fix permissions one last time...

Need help in ext4 conversion

Hi this is what i've tried for hours and still doesn't work. :
Flash XXKPE
Flash XXKPH
Flash CFROOT with custom kernel from skin1980
In CWM Recovery mode :
-Backup
-Install ext4 conversion script
and this is where I get a problem, I try to restore but it keeps saying MD5 mismatch, I've done the whole process again and did a backup with a different name "1" and it still doesn't work !
Thanks for your help
How large is the external SD card? I've had this message with having insufficient space on the external SD and I thought that the backup was successfully made.

Well 32 gb is fine I guess
It is fine. Flash everything again. KPH and CFROOT 09-05-2011. Then do the same process then report to this thread.
BTW, you used the latona pit file on the first flash right? for KPE I mean. Also, try to use the stock kernel with CFROOT first. Don't use the OC kernel just to rule out some gremlins that may cause errors.

I just flashed KPH and the CFROOT stock, did a backup with CWM then installed the ext 4 script in recovery mode, tried to recover ... AGAIN ****ing MD5 mismatch
I think i'm gonna give up this is pissing me off I flashed like 15 times and lost all my data I need to restore...
Wait, do you restart after you flash the ext4 zip then go to recov mode again to restore?
Also, take everything out of your sd card and just retain the ext4.zip and whatever cwm flash zips u need.
Still doesn't work even with restarting and I can't boot since it's stuck on samsung screen T.T

This happend to me before, it causing of fw download corrupted. redownload fw again.
Do not restart after applying the zip and just restore the nandroid backup.
My first attempts were without restarting as told by many posts from others
HI
I agree that you need to redownload All ROM + CF Root
flash ROM, then make sure ROM is OK
Hardware reset
then install CF-Root
make sure All fine then.
full NANDROID BAckup
reboot
then i wish you luck in EXT4
GoodLuck
I faced the same problem a few times, but haven't found the root cause. I have some theories though:
Md5 mismatch means something caused your Nandroid backup to get corrupted.
Do not touch the folder in which the backup is placed.
Do not rename anything.
Do not move the folder or it's contents.
Do not clear the cache in CWM recovery mode.
Format your external SD card once through the settings menu in the phone.
Don't use the windows (or any) chkdsk (error checker) on the SD cards.
Again these are just theories, haven't really found the cause of this error.

How to check if file system is ext4???
@Cix: usually a quadrant benchmark is a good indication of that.
To definitively confirm, use adb shell :
Look up the thread on ext4 conversion and read some of the comments. Or better yet, use the search tool.

[Q]manually flashing

Ive only flashed my phone a few times and they were all through rom manager.
So if I manually download the rom to flash, I would then transfer it to the root of my sd card, but what if there is already an update.zip file on the root? Is that basically the last rom I flashed? So it would be ok to overwrite it?
Thanks, just wanted to save the process of unbricking solely for saving time with trial and error.
Thanks much

Do not delete the update.zip. If you downloaded a rom it will be named something else.
thanks much.
I am going to try the doctorz rom, looks neat.
Instead of using the apply update.zip option in cwm use the choose zip from SD card and navigate to where it is.

[Q] Can't flash anything

Flashed instigator kernel onto chimera mod without explicitly checking to see if it would work (i know)
phone soft bricked
fixed using CWM, restored back up, but could not flash anything afterwards
error looks something like this
E:Can't open /sdcard/ROM/vincom/[rom name].zip
(bad)
Installation aborted
Restored to stock using odin, reinstalled CWM but same error. Installed TWRP but same error
everything works perfectly fine but can't flash anything, same error for any flash
never seen this problem before, don't think its in this forum anywhere
Any help would be appreciated.
Thanks.

I'm on TWRP 2.2.0 right not, can't get back to CWM because of no flashing thing.
as far as i can see no format sd option on TWRP
is wipe SD the same as format on here?
Turn your phone off, then remove the SD card and plug it into your PC with an adapter. Format it from there. I've had better results that way.

Ya its like you are trying to flash the path to the rom instead of the rom itself. Is that error message showing up in the cwm ui or in the odin window on your pc?
If it's in odin.. You can't flash a zip file. You'll need to unzip the zip (7zip?) and flash the tar file inside if it is a odin type file. Otherwise flash the rom with cwm or better yet TWRP.

I'm not trying to flash a zip file in odin.
That appeared in CWMT 6.0.1.4, similar message appeared in TWRP.
In each case it has trouble opening the zip file containing whatever rom i'm trying to flash, doesn't matter the path, rom, sdcard, whatever.
pretty sure there's nothing wrong with any of the files or the sd cards, the phone just can't open a zip package from anywhere.
However, CWM worked, once, going from CWM 5 to CWM 6, only time it's done anything in a recovery.
I have attempted to flash multiple roms including cm9, cm10, superlite, and chimera, in CWM 5, CWM 6 sk8terwitskil's version, and TWRP 2.2.0
EDIT:
i had some luck with flashing a zip that just contained google now.
I noticed today that the sd card worked without my normal files on it (the zip was in the downloads folder) and the major difference that I see is before I restored the sd card files android.secure wasn't on the sd card.
I have android.secure on both the internal and external sd cards, (since restoring my original ext sdcard files) not sure if that's normal or not.
Should i just remove android.secure and see if it works? Can the phone do without it if that's not the problem?
is android secure supposed to be on both cards? My gut says no.
What the **** is android.secure anyway?
are zips that contain just apps or services like google now (non-wipe) fundamentally different from ROMs in some way that would let them flash but not the ROM zips?
Thanks to everyone who has responded and helped so far.
If anyone has answers to these questions I would appreciate it.
