Quick rooting question - T-Mobile LG G2x

Hey guys,
Finally got around to working on my phone. I have a question. I've been following this guide here to the letter. But I skipped step 1 as I thought rooting was only for 2.2 Froyo G2x owners as mine's already been updated to 2.3. Do I still need to root it to flash CWM while I'm logged into my phone??
Thanks in advance!!

If flashing cwm via nvflash doesn't work then you'll need to root first, it's been quite some time since I last did this, but I'm pretty sure all you need to do is flash cwm using nvflash and then install the rom of your choice

Followed the guide here and flashed the root file.
One last question. Can I install roms and kernels from rom manager, or do i do both from cwm?

I honestly never tried to install roms, or kernels, from rom manager, I think you need to buy the premium app to be able to do so. Either way, it's always safer to flash from cwm since you can wipe everything you need to from there (ie. cache, dalvik cache, system, and data) which is very important when flahing different roms, and kernels

Just to reiterate, on this particular phone it's not the best idea to flash with rom manager at all. Always go with cwm.

Super One Click has been updated with a new exploit that can root the G2X Gingerbread without flashing CWM Recovery. Get the new version of Super One Click and root it that way. Or flash CWM Recovery and then flash my root zip.

Cool. I'll do that with the next phone I get, haha!

I will get my 2nd g2x in 4 days. Looking for guide for s-off,root,super Cid I'm guessing flashing a rom is just like any other phone. Has anyone ran an ics rom on their g2x?

Help Please!!!

Alright, I rooted my Nexus S 4G this guide. My phone was running 2.3.5 but I figured that these steps in Terminal wouldn't really change. When I flashed the "recovery-clockwork-3.0.0.5-crespo.img" it didn't install properly (I assume because it was out of date/wrong version) Anyway, I flashed this instead with no problems.
In my euphoria over solving my clockwork problem, I forgot to flash the "su-2.3.6.1-ef-signed.zip" and flashed the current version of MIUI. I am now stuck in a bootloop and I cannot enter recovery by using power+volume. I cannot turn the phone off. I can load the bootloader screen using Terminal while I plug it into my computer, but I don't know what to flash to fix the phone, and start over/end up with a Nexus running MIUI.
i dont know much about macs but you can flash the img files through fastboot.

I can handle the mac part if you can show me which files to flash in which order to make my phone work again.
Okay this will take your phone back to stock. Download the grj22 image files. When you open it up it should have like 4 or 5 img files. After that open up cmd and type in the commands buglesspete has in his first post. It should be under "return to stock" or sometime like that.

Just a general hint... if oyu own a Nexus S 4G, Crespo isn't the right codename to look for.. it's crespo4g. Get the cwm recovery from here and flash the 4G version via "fastboot flash recovery <recoveryname>.img": http://forum.xda-developers.com/showthread.php?t=988686

I have no experience with the 4G version of this phone but I can tell your that bootloops are usually caused by failing permissions (fix permissions in cwm rec) or missing wipes before isntalling the actual rom.
So I'd go back to start, flash the 4g recovery, wipe everything (including "mount and storage"'s /boot and then flash MIUI for 4g from here afterwards.
Basically, that MIUI (and most other custom roms) includes superuser.zip aka root. No need to root the devices before, all you need is an unlocked bootloader.

What he said, I always wipe 3x everything just to make sure it is a clean install. And some people will also suggest to let the rom boot up normally before flashing a different kernel.

wiping 3 times is senseless! and the kernel should be flashed right after the rom install!
oh and wiping the dalvik cache and chache after a rom-update is also senseless! the updater-script do this automatic!

New ROM

Whenever i try to flash a new ROM it doesn't want to load. I've tried the CM7 nightlies and the pheonix ROM. This is what I do.
I root my phone via one click root.
Install clockwork recovery via app.
wipe
install ROM via recovery (install zip)
start up
Locks at LG screen. Ugh!
Any advice?

This is a must for the g2x. If you use from manager it only fake flashes clockwork mod recovery and makes you unable to flash roms.
Typical way to achieve root on the g2x is to.
1. Nvflash cwm
2. Create a nandroid backup.
3. Flash a rom that has root.
Don't bother with rom manager or super one click.

Just as a quick question. Does wiping the system, wipe ANY of my data? Like does it only wipe the existing ROM? Ive been confused of it since the first time i flashed a ROM

Thanks, I'll give it a shot and get back to you. I don't think it had to do with the wipe as I always ran a wipe script before installing. I thought it had to do with the kernel.... (don't have a clue though)
I'll flash the clockwork via nvflash, and get back to you, thanks.
EDIT:
IT WORKS. NVFlash the recovery, make sure to change the command if you have a different version you plan to flash/

you definitely want to do that. do you have a nandoid backup of your original system? if your phone breaks, that is the only way to revert it back to original for an exchange (unless ofcourse you take a hammer to it).
Yeah. I have a Stock froyo backup.

I think so. Catch is that I don't know if doing that will actually update anything, the whole problem is that ROM manager doesn't flash it properly/to the right place. The only thing to do is make a nandroid and try it out and if ti doesn't work, then reflash with NV flash and you're good.

Newbie Help

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!

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.

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 had this happen to me when I tried to flash CNA b4. No matter what I did I could not get out of recovery when trying to flash. I thought for sure I would have to go back to stock but I just fully wiped and reinstalled AOKP with no problems. It may have been a bad download or something but I had that issue as well.

Please help.

So my fiance has had this phone for 2 years, she FINALLY let me root it. I have a SGH-T679, flashing for that is simple, i am able to get a custom recovery flashed via the stock recovery.... On this device it says to flash a custom kernel. to get a custom recovery. im having trouble with this on the stock rom. Everytime i have tried to flash a kernel, for instance basic with a twist, the phone will NOT reboot. idk if im missing something or what, if at all possible can someone help me out so i can get this done for her. like i said on my device flashing is extremely simple, on that all i have to do is wipe rom via cwm or twrp, flash rom and gapps (plus other goodies) and reboot. this phone you apparently cannot do this. Please help me out.
Also I should note I do have root on her device, and when I did try heimdall the device was stuck on boot animation. Left it there for 20 mins.

i flashed over to beanstalk from stock GB with custom recovery <-----you can choose any other 4.2.2 but make sure its Aries build...they simply flash like normal then it reboots by itself back into newer CWM recovery then finishes the flash then you have to manually go into recovery after first boot to flash over the gapps....most roms in the Development threads have the how to install and the proper downloads
So I can flash a 4.2 over stock. I already know gapps and all that. Any wipes need done?
