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.

Thanks for the replys!
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.

If I wanted to manually flash cwm instead of using rom manager, how would I go about it?
I have a version of cwm on my phone that I don't want and want to flash a different version but not with rom manager, I don't want to choose one from that list. I have another one id like to flash I just don't know how.
I was thinking go into cwm and use the "flash update.zip" I think that's how you do it, but I am unable to flash anything from the external card because it wont mount because I have an incompatible version of cwm installed.
Anyway to flash from the internal storage?

Out of curiosity, what version of cwr that's not on rom managers list are you so interested in flashing, and why?

Ok I got the right cwm installed but I STILL can't mount the external sd sonic can't flash anything. What could I possibly do to fix this? Any way to flash zips from the internal storage.

Just in case anyone stumbles across this in the future, I was able to get it worlkng by formatting my sd card. It was the only thing I could do to get CWM to recognize the card.

While your post back is appreciated, I still haven't quite figured out what you were trying to do in the first place. Or why.

I thought the card wouldn't mount because I was using the wrong version of CWM. I tried the version of CWM that was pre loaded with rom manager and it didn't work either. I had another one I wanted to force flash and try it. Turns out the card just needed to be formatted and CWM was able to mount it.

Gotcha. I was just giving you a hard time, anyways.
I thought you were trying to install some prehistoric cwr version 1.0 because it had some secret feature unavailable in the newer models.
yes。wish it nice
I am curious if you're loading 7.1 r1 or not
Is there a way to fully wipe cwm from the phone if it was flashed with NV flasher? I flashed the internal support one when I started flashing roms and now I notice that trying to flash external support roms has put me in a pickle. I've asked before whether I needed to switch support or something and was told the newest rom manager supports both... this is wrong. Upon installing eaglesblood 2.3.5 and installing rom manager...no cwm detected, so I flash it. Now when I reboot doing power and down I boot into an old internal support cwm that only has old backups and access to the internal SD. If I reboot from rom manager it will boot into the new cwm. How do I erase the old NV flash version. It wont hold any new backups, so if I crash it will leave me with old cwm. Plus its a pain when I don't have access to downloads I do via rom manager.....
Summary - old version of cwm bootable through power and down (nvflash version) . New version flashed by rom manager only shows up booting through rom manager. Want to erase NV flash version so there's only one. Frustrated.

No need to erase, just nvflash over current will replace old.....if you flash newest 5.0.1.6 i belive, it lets you choose zip from sd card or internal memory....BUT have the latest nvflash one, its a must if you are gonna flash roms.

I see, what about flashing through rom manager? Is there a way to rid the rom manager install before I do the NV flash... should I not flash through rom manager?

Just have both, make sure both are latest, but the nvflash one is most important. That one will/can save your life (phone)
For all intents and purposes, you cannot actually flash CWM from ROM manager with this phone. All it can do is reboot into CWM from the app. If you ever need to access CWM from a power-off state (bad flash, bootloop, etc.) you will only be able to enter the NVFlash version. Strongly recommend always having the NVFlashed version of CWM. Maybe even give up using ROM Manager altogether.
If you can't do without ROM Manager, keep using it. But it would be a good idea to flash CWM 5.x.x.x through NVFlash so that you have an emergency recovery that can read both internal and external memory.
Thanks Frisco and r4. Totally understand now. Relief. Now to Eb 1.9!

I have been trying to use Odin with no success recognizing my device. So I am giving up for now.
My question is can I use CWM or rom manager to flash a rom without Odin. I am stock froyo 2.2 and was wanting to flash another custom froyo rom like fasty or similiar. Can this be done without Odin? Thx
Sent from my SAMSUNG-SGH-I897 using Tapatalk
If you don't want to use ODIN you will have to find the method to get around the 3e recovery in order to use ClockworkMod recovery. You'll need something like Root Explorer from the Market so you can move files around. Search in the forums for 3e recovery workaround.
When you get that, then just put the zip of any froyo rom on your internal sd card and flash it through CWM.
This is the most simple type of flashing so if I lost you, your best bet is to read as much as you can about flashing froyo roms. Luckily, it is generally safer than trying to start out with gingerbread roms.

Have you considered giving Heimdall a try?
You may also want to check the options in the "Connection Issues" post in my signature.
That's what I needed to know. I put the 2e recovery fix through root explorer. So I should be in good shape. So I wipe everything, and does it matter what CWM I have. I just installed CWM thru rom manager.
PS I am gonna try hemidall soon.
Thx

Theoretically, if you have the 2e recovery fix done you can flash the new rom from the recovery menu with no problems. The new rom will just replace the old one but all your data will stay where it was.
I would suggest backing up and flashing from stock because most roms run better this way. But, to each his own.
Lastly, Rom Manager sucks for Galaxy S phones. You should really learn how to use odin because there have been some problems when people use rom manager.
Can anyone tell me what I'm doing wrong:
a) ATT Infuse Phone is rooted using SuperOneClick;
b) downloaded ES File Explorer and ROM Manager;
c) ZEUS Build 3 zip file is in root folder of my sd card;
d) backed up everything with Titanium Backup;
e) placed the 3e recovery no sig check recovery file into my system/bin folder;
When I try to reboot into CWM recovery, it goes into the "blue" 3e Android recovery. When I install packages, I get an error message.
Then when trying to flash ROM through ROM Manager, I cause a Samsung bootloop, and have needed to flash back to Odin to unbrick my phone.
Is my problem related to the fact I'm flashing from stock froyo? Do I need to change the kernel (not sure what this means) prior to flashing the Rom? Why can't I get the CWM bootloader instead of the "stock" blue Android screen?
thanks in advance - sorry, am a newbie and this isn't my thing.

Is it normal when I flash GTG's community kernel, that my phone starts talking to me and saying something about 10 minutes?? It just scared the #$# out of me, and has been sitting in the Samsung boot screen for a few minutes.
Holy #@$$, that voice is scary. It looks like the kernel worked...

You need to install the community kernel, then download sgs kernel from the market and install. I had this same problem and this was the answer! http://forum.xda-developers.com/showthread.php?t=1220090
Follow these instructions and make sure you download this http://www.multiupload.com/1E3AWIQYAA if your coming FROM froyo.
Move the file to your internal sd card, then use sgs kernel to install. The sgs was a little tricky, but you'll see the file in there to flash.
Hey thanks for asking DroidNooby! I was searching the forums for "bootloaders" because the Zeus thread said "MUST BE ON GB BOOTLOADERS." All I found was a bunch of people sounding as confused as I was asking "how do i install?"
I was beginning to think it was an inside joke of the Infuse forums lol.
Odin one of the gb leaks (that'll give you boot loaders). Then odin a gb kernel with a recovery. Uncheck reboot before flashing kernel. Then boot up into recovery and flash.

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.
