So after reflashing to stock in order to try the new update, I realized that it unrooted my phone. I was kinda down by this but I thought maybe I could reflash cwm in order to flash to a new rom. I ended up flashing cwm successfully without rooting the phone and was able reflash miui and now all of the backups I have are using the new baseband with no issues. The problem I found most people were probably running into when trying to use the LG updater tool is they were not removing the SD card prior to flashing which prevents the update from completing successfully. Just thought I'd share my two cents.

Hmm.. if this is true it would have been nice if they told us to remove the SD card. Unless I missed that somewhere.

I flashed just fine with my SD card in.
It doesn't remove Clockwork mod recovery so just flash a rooted rom. They have the lastest GB stock already rooted in flash form. Just flash and you'll have root back. Easier then trying to root it as I don't think the new GB rom can be rooted yet (could be wrong).
Easier to just flash
LG G2x - CM7.1 RC1 2.3.4

I tried to flash mine with the SD card removed and completely lost my baseband. I had to send my phone back to LG for repair/replacement.
in the directions that were posted by tmonews that were official from LG, the directions state to remove SD card, when you flash the update, it puts it back to the stock recovery, at least it did for me, so when i re-flashed cwm i was able to keep all of my other cwm backups that now have the newest baseband.
Just followed the video this morning to make sure I did the right steps. I got CWM on there but won't give me root.

No issues here with updating and having a sd card installed.
@bow...did you download the rooted rom from xboarder? It is a zip. Install it after using the LG tool and you will be good to go.

Sorry newbie here, just want to be really really sure as I followed a poor guide somewhere and got stuck up with the google logo and lock on boot, hence was forced to install cyanogen.

UPDATED: 7/8/11
Okay..so to close my question. I just followed this and everything went back to stock.
theunlockr.com/2011/01/20/how-to-unroot-the-nexus-s
1. followed the link above.
2. I remain rooted but recovery went back to stock. no more clockwork.
3. after booting, was alerted of a 2.3.4 update..so I updated again.
4. marketplace has been upgraded to the new interface (probably bec of the update)
5. to install screenshot app and fontchanger..I needed to have super user, so I just installed Clockwork (recovery-clockwork-3.0.2.4-) again and installed SU (su-2.3.6.1-ef-signed.zip) via SD card install.
6. so far, everything's good.
If you have some questions, feel free to ask.

Is there a way to return to stock while keeping CWM ?
You can stay on stock rom while you are rooted. You can google it. I got my 2.3.4 from ardoid.com
Its a stock rom with added arabic support. Since you dont need arabic. It wont make any difference to you.

I'm not asking for keeping root, only to revert back to stock while keeping CWM
Clockworkmod will stay on your phone. As far as i know, all your phone recoveries will be done through cwm

I read somewhere that flashing a stock ROM will restore the stock boot/recovery. Is it true ?
That i cant answer u. But i can say that i went back and forth between roms. Reverting to stock when needed. CWM stayed on my phone.

Thats what im trying to say. The only way (i think) to lose cwm is using odin. But you can find zip stock roms. Thats what i did

Hey Guys,
Brand new owner of the G2x and Android for that matter ( had an iphone before)
Of course I am looking to flash some roms and see how they are. The phone is rooted, and I downloaded rom manager and flashed CWM. But now I am reading and seeing that it is safer to use NVFlash? Do I need to remove CWM or w/e before i can flash NVFlash? Do i even need NVFlash?
Thanks in advance.
Rom manager flashes fake cwm. U don't need to remove it though. But u have to flash it again via nvflash. Otherwise u won't be able to root or flash any custom rom.

Another question is:
Is this possible to do without a SD Card in the phone? If so, where do I copy the flashable zip files too on the phone?

Not on the more recent CWM, you'll need a SD card.

If have the latest CWM (5.2.0.0 I think?) You can flash zips by selecting Flash .zip from SD card > flash from internal SD. You can place your .zips anywhere you'd like.

You actually can use the rom-manager-cwm to flash roms. With the G2X, rom manager has 2 issues that I've encountered. The first is the one mentioned already: that it doesn't actually flash clockworkmod recovery to the recovery partition. The problem here is that if something goes wrong and you can't boot into android, you also won't be able to boot into cwm. As you stated, using nvflash installs cwm to the actual recovery partition so you can boot into it even if you can't boot into android.
The second problem I've had with rom manager on this phone is creating and restoring backups. The backups created with rom manager won't restore properly. It's been a while since I've used it though so maybe that's been fixed.
Either way use nvflash. It's the most reliable method for this phone and the only way to actually flash cwm to the recovery partition.
You have to use nv flash or if you run into any problems you won't have a recovery. Nv flash is both simple and difficult. If you have any questions just email me at [email protected], I will be happy to help you in any way I can. I'm a full time writer at ACS, so you can find me there also.

Hey Guy's I'm currently having issues flashing the official MIUI rom via cwr mod and I have no clue what I'm suppose to do at this point.
Right now my phone is using stock gingerbread 2.3 (tmobile) and I am using the newest version of clockwork recovery.
The main issue is that every time I try and flash it it gives me a SD mounting error, but i can flash cm7 off my device...anyways any help would be appreciated

Well after a lot of browsing and searching I'm able to put custom roms internally, but every time I flash cyanogen mod it doesn't recognise my internal memory and it automatically assumes I have a sd card in my phone.
btw thanks for the reply
oh and its p999
sorry double post
Ok just got this phone and have decided to go with Phoenix Blood rom, but how do i start? I have to be on froyo to root? Im coming from samsung epic on sprint that i flashed so im not completely retarded. Thanks for any help
Use superoneclick to root on froyo.
If your on 2.3.3 gb there's a flashable. Zip in development section to root.
Also you will want to use tgagunnmans nvflash method to install clockworkmod recovery in dev section.
Phoenix blood is a great choice btw, enjoy!
Sent from my LG-P999 using xda premium
You're still on Froyo? To my understanding it's a good idea to flash the OTA GB first so that you'll get the up to date baseband. Once that's done just go ahead and flash PB.
no im on gb jsut thought i had to go back to froyo to root, so i just flash clockwork mod then pb and thats it?

Yes, but make sure you're using NVFlash to get CWM. Don't use Rom Manager.
Easiest way is using the tool unlockroot. It supports gb on the G2X. Or you can use nvflash, whichever you prefer.

If he wants to change Roms he will still need Nvflash regardless how he gets it rooted.

From that thread:
Flashing the custom recovery using NvFlash is the only way to ensure that in the case your phone will not boot up, you will be able to get into recovery to fix the issue / flash a ROM / restore from nandroid backup. That is what this app will do for you.
If you flashed the ClockworkMod recovery from ROM Manager it does not flash the recovery to your phone, it fake flashed it. The only way you can gain access to ClockworkMod recovery is through ROM Manager at that point. Using this method is the only way to flash recovery so it is persistent and accessible booting to recovery.
If you have already flashed through ROM Manager you can still proceed with this method. Flash Away!
(You can use both ROM Manager CWM and have the nvflashed version working together. You just access either or one at a time, having the nvflashed one means you can boot to CWM. Welcome to Tegra2)

Follow the link. This is a must for tegra 2 based phones. It is always better to be safe than sorry and it also allows you to do a ton of other things, such as making backups and flashing roms. Let us know if you need help. The phone is pretty much unbrickable after you do this. It gives you the ability to recover from any major mistake.
Its in the dev thread, it low level flashes clockworkmod recovery to our phones internal memory partition. You need to install apx drivers first in order for the g2x to be nvflashed.

thanks for the help guys got it all set up
Just to add in, nvflash allows u to boot into cwm recovery whenever u want and u don't need to be next to a computer. I think that is how it worked for Samsung phones and Odin, where u needed a computer, but haven't used a Samsung phone so I could be wrong. Remember always make a back up of everything and play around with the different roms, not every rom works for everyone
Sent from my LG-P999 using xda premium
Actually Odin is just like nvflash. It is used to put cwm on you phone and to put the stock recovery back on.
Once you have cwm you can flash what ever rom or kernel without the need for root. Just back up your stock unrooted stock rom before flashing anything else.
If you do that you will have your own stock backup with no need of finding it in the forums if you need to go back to stock.

I wanna know if you can install a ROM with the 21y Baseband added or do I have to go about unrooting and go via LG Update and install the 21y Baseband, I rather not have to go unrooting and such so is it possible to do it without unrooting my G2x?
No ROM will add it for you. unfortunately, when you get on the new base band, you will lose root as well as cwm. No other way.

I also went back to stock GB, but was unable to do the OTA said I had Latest version. So I went through the LG updater tool with no problems running on Win 64. After confirming latest BB I also NV flashed CWM back and went right back to HFS 1.9 rom. No problems.
