G2X Going back to Stock Reovery - T-Mobile LG G2x

I have rooted my LG G2X and flashed the Clockwork Recovery image using ROM Manager. I have read that this is a "fake flash" but I have booted into recovery using ROM Manager and done a nandroid backup and it seems to work fine? I have a 2 GIG SD installed and it looks like Clockwork only works from the external SD card?
I am running the stock ROM at the moment until I can find a stable custom ROM to use as my daily driver. I want to keep the phone rooted and the recovery image intact until I find a stable custom ROM.
I am looking for the procedure to flash back to stock recovery and unroot if I have to return the phone for repair to T-Mobile in the future. If there is a stock recovery image that can be flashed using clockwork or a one-click method, I would greatly appreciate it.
I have the G2X Model LG P999

If you continue to boot into CWM using RomManager (for now) your stock recovery is still intact. If you want to return to stock from the point you're at, stick the stock nandroid restore image on your sd card and restore it. Then uninstall Titanium Backup and unroot the phone using the SuperOneClick root program. If you would like to continue flashing ROMs I suggest doing a *real* flash of CWM (which you can still reverse in the future) in case you end up in boot loops and cannot access RomManager.

[Q] ROM Manager bricking phones...?

Could ROM Manager fake Flash Clockworkmod recovery be responsible for bricking phones on LG update? Let me explain what I mean - Lots of people, like myself, installed ROM Manager and its CWM because we did not know it's not real Flash. Then We switched to "real" CWM. Now the question is when we do normal stock recovery in order to get official GB update, does this CWM of ROM manager still remains in the phone? If so, could it be that it contributed to the troubles updating through LG tool? How can I make sure I removed it from the phone?
Thanks!
Yes. Many people have confirmed that not having the stock recovery on the device is a road to Bricksville. Even though you are fake flashed there is code inserted somewhere to redirect to the fake flash, and the recovery images for flash (normally installed every boot) have been deleted or renamed. You should flash stock recovery with NVFlasher to make sure you are back at a clean stock recovery before using the LG Update tool.
Thanks but what I mean is that AFTER I realized it's fake flash I installed "real" CWM. So when I do stock on this "real", does CWM rom manager still remains in the phone and how can I remove it?
post deleted by poster
so I am a little confused I used CWM to make a backup before I did anything to my phone. And I was already on the 2.3.3 lg update. So if I restore that I should be back to stock and CWM should still be there right? But lets say LG comes out with another update (Doubtful) and I want to use it I should use the NVflash to reture the phone to stock? if I use NVflash will that put me back on froyo 2.2.2 or GB 2.3.3?
Also I used rom manager to make a backup of the rom I was on which was the stock rooted so is that fake or what the hell is fake? is it the first option in rom manager the CWM recovery? is it the same if I use CWM stock recovery? in cwn itself? Oh I am so confused someone help me
ROM Manager cannot flash directly to the phone so it "fake flashes" CWM recovery. It only installs a few files to the system so that when you run recovery the stock recovery runs an "upate" and that launches CWM recovery from your SD card. Just return the phone to GB 2.3.3 stock and be happy with it. If you restore using CWM it will remain there, so you should use NVFlash to restore stock recovery also.

I have BOTH - CWM AND CWM through the ROM Manager. So if use NV Flash to go to stock, is the CWM from ROM manager still in the phone and how can I remove it?
Thanks!
so what I am getting out of this is rom manager is crap and dont use it. If you just use CWM to do your flashing and backups and recoverys you should be ok.

Thanks but my questions are:
1. If I go to stock using NV Flasher, is ROM Manager's CWM still going to be in the phone, since I have BOTH?
2. Can it BRICK my phone if I do the LG update then?
3. How can I make sure I removed BOTH - NV Flash CWM AND ROM Manager CWM?

Stuck at splash screen after CWM nandroid restore

I have:
Infuse
Infused ROM V2
So today I downloaded "ROM Manager" and "ROM Manager Premium" from the market. AFAIK, this means they are up to date as of today.
Then installed CWM Recovery.
Then installed the 3e mod fix.
Then booted to CWM and did a nandroid backup.
Then booted normally.
Then attempted to install MYUI via ROM Manager download.
It bricked the phone.
Restored the phone with Odin.
Rooted.
Then installed both ROM Managers.
Then installed CWM Recovery.
Then installed the 3e mod fix.
Then booted to CWM and did a restore from the new backup done earlier in the day.
Now it just hangs at the Samsung splash screen.
Any ideas? I have a LOT of investment in the backed up ROM and don't want to lose it.

I dont know what ALOT of investment is.......but what i think happened here is this<<
You were on Gingerbread right, Infused v2.x.x and you made a Nandroid(thats fine)
u installed miUi and didnt have the luck you wanted...Thats fine
You went back to stock, and rooted and modded the Recovery so you could restore your nandroid....Thats fine
But if you went back to stock(Froyo Right) and try to load up a Gringerbread Nandroid on top it shouldnt work. Nandroids only back up the ROM not the Kernel......so you were in a sense trying to run a Gingerbread Rom on a Stock Froyo Kernel......
Go into CWM flash your Kernel, or use odin and flash a Ginger Kernel then go into CWM and RESTORE.
Happy FLashing
Didn't know that! That may explain a lot of my ROM frustrations.
I'll try this and report back.
Off to go find a suitable kernel....
I really should get my post count up so I can get past this horrible 10 post restriction.
Did you try initiating the flash through CWM or through ROM Manager? Honestly I don't prefer to do any work via ROM Manager, I always have more luck going through CWM and starting a flash from there. Kernel is the first place I'd start but you should also Factory Wipe and Cache Wipe each time you move between ROMs, sometimes you get very lucky and don't need to, most times you bork your phone, and if you're nandroiding back from a backup wiping before you restore is good practice just to make sure you don't leave anything behind from your old ROM.
I installed a gingerbread kernel:
http://forum.xda-developers.com/showthread.php?t=1212485
Version 1.1.
But it didn't work out.
So now I'm fighting with trying to get a stock Infused V2 ROM on there.
No luck yet. Once I do, I'll try the recovery again.
Btw, I'm using CWM for everything.
Go to mounts and storage in clockwork recovery then select format system then do your nand restore ...
Sent from my Samsung Infuse 4G - 1.6ghz
Wow, I was totally making some rookie (which I am) Android mistakes today.
Every time I tried to restore the backup image, I was doing it in CWM by selecting "install .zip from SD card". When I SHOULD have been using the "backup/restore" function.
I'm up & running again. All original apps/settings are restored. Great!
Now to start breaking things again, since I know how to restore from backup now.

unroot confirmation

hey all, currently have a g2x rooted with cm7, and i've been looking to unroot;
just to make sure i dont do anything stupid, i wanna run this through with you guys:
first i would flash the stock 2.3.3 ota rom for g2x
then use the http://forum.xda-developers.com/showthread.php?t=1056847 (one click nv flasher) to get back to lg stock recovery by clicking 'flash stock recovery' (do i need to dl anything extra for this?)
then im done, correct? if i boot up, ill get all the stock rom and apps and bloatware and etc back right?
thanks!
edit: how do i know which version of clockwork mod i have installed? im not sure if i did the external sd support or not...
You've gone back to a stock ROM, you've gone back to the stock recovery, but you haven't actually unrooted.
Whichever method you used to root, you should be able to use that same method to unroot.
UPDATE:
I was originally under the assumption that your 2.3.3. ROM was rooted. If it is stock you should be fine.
sorry for bump, but i read in tga_gunmans post that ppl should flash a rooted 2.3.3 rom and use superoneclick to unroot...would my method work too?
No your way would not work because the stock OTA by xboarder is rooted. Do what tga_gunman said. Flash the rom, use my unroot zip in CWM (deletes root files) and then flash the stock recovery. Busybox will still be on the phone but nobody should be looking for that.
Unroot zip: http://www.mediafire.com/?2vr7cmgg7qcdn14
Easiest way to confirm if your not rooted would be to install Superuser from the market. It'll tell you if the phone's not rooted.
There is an app on the market called Root Checker which is free. It will tell you if you are rooted or not.
A little extra help for me?

Thanks for your help jboxer. Forgive my noob-like understanding of rooting/unrooting terminology. Hopefully you'll be able to understand what I did.
Last night I went ahead with the unrooting process on my G2X which was running Gingerbread & CM7 following this youtube video (can't post link due to noobiness: watch?v=ryGIv8KQVIE), the order that this guy goes in is:
1. Wiping all cache/user data/formatting in CWM recovery
2. Restore to a barebones stock data in CWM recovery
3. Flash to go back to Stock using OneClickRecovery
4. SuperOneClick to unroot phone
What I ended up doing was restoring my phone to the backup that I created on my sd card when first rooting my phone rather than download that zip file in the video description which is a completely fresh start.
However, whenever I flashed to go back to stock using OneClickRecovery, it gave me that total barebones fresh start where I had to completely set up my Android from the first start screen and I lost my backup. Also, when I go to unroot the phone with that zip file, I don't know how to 'install from zip' after I've lost CWM Recovery menu. So, I flashed back to CWM so I could recover my backup from my SD Card again and install the 'unroot.zip' that you linked and it ran alright and I restarted, but I still had 'SuperUser' in my App drawer telling me that I was still rooted.
I ended up calling it good last night after spending two hours on it. I left my phone rooted, with CWM recovery still on my phone, but I at least I had my backup Gingerbread image with no CM7 mod. So, my phone is functional, but I would like to complete this process of unrooting completely.
Could you perhaps give a little guidance and clarity to what I'm missing or not understanding? I'd love to unroot/flash back to stock recovery/remove all evidence of rooting AND keep my recovered backup that I have before I even started rooting my phone.
Thank you so much for all your help, everybody.

[Q] Rom flash fail----Help

I have a lg g2x that I previously rooted and installed clockwork mod on. Today I tried to flash the weapon rom and it failed. I followed the directions posted here http://forum.xda-developers.com/showthread.php?t=1207125
Instructions on flashing
1. Download zip and place on sdcard
2. Reboot into clockwork recovery
3. Perform a factory reset
4. Navigate to mounts and storage and format /system
5. Choose Install zip from sdcard <-----This is where it failed. I got the message installation aborted. Now the phone hangs on the lg start up screen (with the blue bar)
the file on the sd card weapon g2x_30_r1-1022.zip (didn't unzip or edit name)
I have clockwork mod 3.1.0.1 on my phone and can hold the volume down & power to boot to clockwork.
EDIT: what format should the card be formatted ? I pulled it out the phone to add the file so I doubt that's it J/W
I ASSUME I can flash other roms....but I want this one and I got a feeling since I did everything right with this rom others would fail also.
any help is greatly appreciated
you need to update the Clock work mod first of all, and second you messed up by attempting boot a phone that has no rom on it... just redownload the rom and update the CWM to 5.0.2.0
the phone hangs at lg start up screen and doesn't start......how do I update clockwork mod?....so by saying I had no rom on the phone that file (weapon g2x_30_r1-1022.zip) is an update to a rom ?
Can I download another rom to the SD card from a computer and boot from clockwork mod?
I fixed my phone. I downloaded the stock gingerbread LG-P999-V21e file and my phone is up and running with root.
Before I tried to flash my phone I had a stock froyo when I did my nandroid backup with clockwork mod 3.1.0.1
Before I try to flash more roms I will download the newest clockwork mod. Do I have to perform the nandroid backup again? Or is the current backup sufficient ?
EDIT: I just noticed the camera folder (NOT saved to SD) and some ringtones from soundboards are still on my phone...but how? a cache?

delete the last backup and nandroid again. The last backup you did was with another version of the CWM so it won't restore with the new version of CWM that you just updated.

[Q] Does a Nandroid backup back up recovery as well?

I have the Verizon Galaxy S3.
I had no modifications on my phone at all; it was stock everything. I wanted to install Hyperdrive on the phone so I went through the usual steps.
1) Root
2) Flash CWM
3) Create nandroid back up within CWM
4) Flash Hyperdrive ROM
I used Hyperdrive for a few weeks, but then I wanted to go back to stock, so I restored my backup. I was on stock for another few months and then OTA updates started coming in. I know that I cannot install OTA updates with a custom recovery. (I assumed I still had CWM)
So here is the thing...I thought that the backup I made was in the state of being rooted with CWM and stock ROM. So I assumed that after restoring the backup, I was rooted with CWM and stock ROM. So I double checked and found that I was not rooted and I had stock recovery installed. Does anyone know how this happened?

After you rooted and installed CWM did you let your phone bootup first, then boot back down into CWM then do the backup? Seems like you didn't do that. Your Root, CWM did not loaded when you run the CWM backup.

It does not backup your recovery, but you can backup your recovery partition separately. If you restore to stock it will still nag you to update. To stop it you need to freeze sdm1.0 and rename fwupdater.apk.
The update should fail, but if you're unlucky it'll go through enough to lock you down and stick you on 4.3. So either change the rom as soon as possible or freeze and rename the apks.

I believe I used a 1 step script to root and install my recovery. Something very similar to http://forum.xda-developers.com/showthread.php?t=2332825
I had my phone booted up, plugged into my PC and I allowed the 1-click script root it install CWM. Then I rebooted into CWM, and did a backup. So by not rebooting my phone after doing all this, then the root and CWM were not in the backup? Why is that the case? if I am able to boot into CWM, doesn't that mean the CWM already sits in my recovery partition? Thus, if I do a backup of it, shouldn't I get CWM in the recovery?

A nandroid doesn't backup your recovery, only your data, sd card, and caches. It's the same cwm installed by casual.

If that's the case, then how could I possibly be on stock recovery? I definitely needed CWM to install Hyperdrive and to create the Nandroid backup that I used to restore.
Currently I'm not running latest cwm, but I'm runing TWRP and it does backup recovery and efs by default. I'm sure that cwm can do the same but is it set by default? I don't know. here the info I found on cwm:

Some roms are capable of reinstalling a stock recovery. Sometimes if it's not taken out of a rom, it will sense you have a custom recovery and reinstall the stock recovery over it.
Most of the time it's taken out of the touchwiz roms, but I guess in this case it wasn't.
That's the only way it could happen.
Additionally, that isn't even cwm, that's philz touch recovery, those features are unique to that recovery only.
