Really messed up G2X

Well I ordered a G2X the other day and finally I received it. It came with Gingerbread 2.3.3 from the factory. (worked flawlessly) Keep reading.
After a couple days I wanted to try out CM7 on it. So, I rooted the phone by using NVflash and doing all that good stuff, then I flashed the phone with (Gingerbread OTA 2.3.3 Rooted flashable zip v1.0.0) I couldn't get root with SuperOneClick so that was my only option. Well I got root and that's when the fun started.
I installed CM7 on it, seemed to run fine, looked fine. But simple me, I wanted to go back to Plane jane 2.3.3 So, I did all the usual stuff (backing up, wiping data, formatting caches), then I ran OneClickRecoveryFlasher...and restored the phone with LG-P999-V10f.zip (supposedly a stock flash for 2.2.2)
well it all seemed to work fine apon finishing. It booted fine, ran ok. However now I have some really bad problems. The major one is that my wifi doesn't work worth a damn now, the connection is highly intermittent. I can't use the market to download apps because it dies out often, along with anything else network related. (browsing works 5% of the time) You catch my drift. My other android phones have no trouble with anything. Now here where it gets weird, I supposedly restored my phone back to stock. However, the phone reports a proper android version 2.2.2 which is what I flashed it to. However it shows kernel 2.6.32.9 Baseband is July 15th 2011. When I use LG's phone update tool it says I am running V21E which is Gingerbread 2.3.3 ...but that's not true because it is actually 2.2.2
I have no clue what to do, I am stuck. I just want to either have a stock G2X running either 2.2.2 or 2.3.3

You are probably going to have use Xboarders ROM then flash the unroot.zip he has in this thread http://forum.xda-developers.com/showthread.php?t=1158513.
See if that works to get you back to 2.3.3 completely stock.

It says that because it checks the baseband to see how recent it was, that's why it thinks you're on v21e.
As of now, there's no way to flash back to the old baseband, since people don't include the baseband in their ROMs, as that can cause a whole host of problems. The solution is to do exactly what tidewaterns said, that just gives you a little extra background info.

I am going to give this a try and see what happens, I will post results.

Well I tried the slimmed down version of Xboarders's rom and it seems to be working well so far. I originally installed his Stock OTA rom and that's when I started having problems. Oh well. thanks guys for all the help.

Crash course about root and roms: Superoneclick roots the rom you have in place. Flashing xboarders rom didn't "give you root" for the other roms you flashed, it is simply one rom out of many that is pre-rooted by the dev who packaged it up. When you flash it you have a rom that is rooted. If you had flashed CM7 (another rom that provides root access to its system files) then you'd have had a different rom that was pre-rooted by its dev.
Are you catching what I'm saying? Flashing xboarders rom didn't "give you root" any more than CM7 "gave you root." Root is built in to those roms.
If you want to restore to an unrooted stock rom browse the threads in the development section. There are a couple of stock nandroid backups posted that you can restore via clockworkmod recovery and then you'll have a stock unrooted rom. You can even do that and still have clockworkmod recovery in case you want to flash a different rom to your phone again.
And PLEASE remember when flashing from one rom to a different rom, WIPE WIPE WIPE data, cache, dalvik cache, then flash rom, then fix permissions, then reboot. This will save you SO MANY headaches.
G2X CM7

I learned something new Thanks for the info. And yes, this last time when I installed, I wiped and formatted just about everything I could possibly do, including fix permissions..seemed to do the trick.

Sweet! If you're simply updating to a newer version of the same rom you can probably get away with just wiping cache and dalvik cache and then flashing. Its just when you switch to a totally different rom that you need to do a full wipe. Gives you a clean slate to start with.
G2X CM7

I'm curious about one thing though. What would I accomplish by using Nandroid and flashing a bin? I see there is a BIN_LGP999AT-01-V10f-310-260-MAR-27-2011+0.zip file that is available for this phone, although I have no clue on how to install Nandroid. Anyways, wouldn't flashing a BIN be the ultimate way to restore the G2X?

[Q] Got a few questions about gtg465x ultimate Unbrick and flashing new roms

To catch you up on what I'm running
I just flashed a backup of infused 2.1.0 but i had been running infused 2.2.3. Ive been experimenting to see why I'm having certain problems with my roms that i don't believe existed when I originally started use the infused roms.*
However my first question is will gtg465x ultimate Unbricker completely take my phone back to stock out of box state and unroot it?* I ask because when I first flashed a custom rom I didn't properly make a back up of my stock configuration. So basically I'm trying to find out if that matters or will they Unbricker solve that problem?
Next I have some questions about flashing new roms (not updating them). When I first flashed the infused rom it converted my partitions to something else (I think that's the voodoo lagfix) but does this mean anything or will other roms need to be dealt with differently like by wiping the data and cache?
Oh and also would the kernel I'm running possibly be creating the problems in experiencing with my roms?
If you need anymore info in order to try and answer something just let me know.
Thanks guys

Gtg's Ultimate Unbrick will return your phone to stock and unroot your phone.

Nice. So that means if we ever get official gingerbread update I can flash back to stock and download it

Can someone please help me get back to Gingerbread?

First off, just let me say that I am not a complete newbie, but I am fairly new to this so bare with me, I am sorry.
Ok so here is the story. I got the phone new with froyo and then got the OTA update for gingerbread.. I hated the the new camera app, so I rooted, flash clockwork recovery and flashed back to Froyo. Well I got sick of Froyo because besides the camera, gingerbread to me is way better. But this is where I have problems. I tried to flash back to stock gingerbread and it said "installation aborted" every time and I have no idea why. I tried to update through LG updater with no luck, and I dont know why, maybe baseband? So I get pissed and unroot and flash back stock recovery, which is where I am at now. All I want is to get back to gingerbread and be official so I can be all set to get any future updates if we are so lucky to get one? I'm not expecting an update but I'll be happy with the phone in gingerbread with stock rom, I had my fun with custom roms, dont care for it anymore. I didnt do any back ups, and im currently on 2.2 everything stock.
Can anyone help me? Point me in the right direction?

back up everything you want off your phone to your PC. This will wipe everything. Follow the guide exactly.

[Q] I can't decide, to flash or not to flash...

I can't decide, and I'd appreciate your advice. I'm kind of noob. I flashed a custom ROM on my mytouch 4g. And I only did it once. Afterwards, I kind of regretted it because the ROM seemed to be more buggy than the stock. Now, I'm waiting to get ICS on my sensation, but I keep looking through the threads at the ICS ROMs that are already out there and they look sweet. I'm not sure if I want to wait for the ICS OTA, or just flash a custom ROM. The only things that are stopping me from rooting my phone are the fact that I am kind of a noob, and I don't want to flash then have the OTA happen the next day, and have it screw with my stuff. Would I be able to go back to stock after the OTA, and then just have tmobile push the OTA? Also, I have a mac... and I'm pretty sure I can't use a mac for flashing new ROMs. I don't mean to be redundant and I hope this doesn't piss anyone off, cause I see a new thread everyday about the new ICS release. Thanks for any feedback.

You can revert back by flashing via RUU, after this you can receive the official OTA when it gets pushed. Now the part about you having a make may cause some problems. I suggest you do some Googling and find a good virtual machine to run Windows with on your Mac.

i would flash
i think you should definitely flash a custom rom. since the sensations release many roms out now have fixed issues of being buggy/ slow and battery draining. im using the newest insertcoin rom and had android hd revolution before that. both are super smooth and fast. as for reverting to a stock rom, i believe all you would have to do is find the update RUU file for the stock rom to go back, this will cause you to lose root, but after you flash a rom you'll probably feel no need to go back. and always make a backup
btw 1st post

I came from the mytouch 4g as well. If you rooted and flashed on that phone you will do just fine on the sensation. The sensation is about 100 times easier to root than the mytouch.

New to Android and been reading.

Hello everyone. I received my Verizon SG3 shortly after it came out. I have been doing reading as I am very new to android. This is my first android phone. Previously I had an EnV Touch. Hated that thing, but it did the job. So any who I now have this awesome kick butt phone and it has all the Verizon crap on it I cannot get rid of. I have rooted and the bootloader is unlocked. I used a windows program to gain root and then used EZ unlocker to unlock the bootloader. I have been looking and looking to figure out what rom I want to start with, I want JB, but don't want a lot of bugs ATM as i don't have all that much time to play with flashing and being still so new I don't want to end up with a brick. I tried my harderst to figure this out by reading, but the info seams so spread out, I kinda want to try the CM10 9-6 as I have read it is stable and not many bugs. My main question is about kernels. Am I correct in thinking they will get flashed just like my rom will in ROM manager? Or do I need to flash through CWMR? How do I know what Kernel to use? I have been reading the CM10 takes a different kernel than say synergy or stock. Or will the stock kernel work till I load the proper kernel. If I knew about the kernel and how vital it was to go with the ROM maybe I wouldn't be so paranoid. I have a friend with a GS2 and he told me the kernel has to go with the ROM and if the two don't mach then you could brick. I can't afford a brick my first time around.
If you could give me some advice or point me in the direction of some more reading that would be great.
Thanks
JB

All ROMs come with a kernel in them. Typically you just stay with it unless you want some extra features or what not. There are aosp kernels and kernels based on the stock firmware. If you use a touchwiz based rom you need to use a touchwiz kernel.
I don't think it will brick it if you interchange them. It will just boot loop
Edit: you flash kernels in recovery just like a rom. if you change kernels without changing roms you need to wipe cache and dalvik cache through recovery also.

Back up your IMEI before flashing anything, alot of horror stories floating around. Development has some fantastic guides. After that, most of the "big gun" rom's here have kernels, and are for the most part consistently the same flash method through recovery. Cwm recovery is solid and reliable, start with that until you feel comfortable enough to venture off. Make sure it's version 6.0.1.2 (regular or touch) for any jelly bean based rom.

I backed up the IMEI with the terminal emulator. So if the error occurred it would restore with the proper IMEI. Should I back it up any other way too?
Also I'm planning on using the Rom manager to flash the Rom. Do you not recommend that or should I do it manually with CWRM?
Thanks for the replies. I'm still getting my feet wet and know all about searching before asking. Used to program dish.

Your call, depends how paranoid you are! I would flash manually, it's a control thing for me, I know what/how/when all was done. Using 6.0.1.2 touch is awesome, speeds flashing up considerably.
Sent from my SCH-I535 using xda premium

I might have to try the touch. I have standard 6 on there. The one you listed. Rom manager gives me the option to load touch too. Friend uses Rom manager on his s2. Looks to just automate things a little.
What I don't know is if it wipes the appropriate areas first for a clean install or if it's doing it dirty.

Use the Synergy backup. If you lose your IMEI you just flash it again and it's back. Just make Nandroid backups and flash away. This is my first Android phone too and now I get why people become flash addicts, it's amazing what you can do. It's easy to relock and unroot if need be. Everything is easy if you take it smart and slow.

Just stick to a couple rules and you will be fine. First is backup, backup and backup before flashing. Always stay within the Verizon SGS3 section, Sounds simple but others have made the grave mistake. When flashing kernels, stick to the software, ie flash a JB kernel to a JB rom, flash a ICS kernel to an ICS rom. You should not have any problems but if you do you always have a backup. There are many roms, just flash an try them, make sure to read through the threads to identify any issues that have been discussed. JB roms there are a couple, a TW based JB rom from a T-mobile leak that was ported to VZW SGS3 that works well, there are official and unofficial JB vanilla roms, ie CynogenMod. Stick to those rules, keep a back up, i usually will transfer a copy of my original backup to my pc just in case, and always backup to external sd card. Good luck and have fun.

You can also flash kernels via Odin I believe.
