G2X and July Baseband

I have a G2x and my Baseband is Mar27 2011 I have read on here that the July15 2011 baseband might clear up issues and make the phone work better is this true?
I am also rooted on a 3.3.4 ROM if I updated the baseband can I reroot my G2X?

As far as I know, nobody has uploaded the july baseband. I think the only way to update it would be through the lg tool or ota.
I don't know about one-click rooting, but if you get the baseband through the official update, you can always just flash prerooted gingerbread.

Sorry I wasn't very clear I was talking about going back to stock and then using the lg tool and update to stock 2.3.3 that has the July Baseband. I want to make sure I can reroot back to other roms after I do this and if anyone has done this knows if the July Baseband is better than the March one?

1. 2.3.3
2. Yes, you can reFLASH other roms after updating to the new baseband, and root them.
3. For some, the new baseband has fixed gps issues. Others seem to be having issues with the data signal.

yeah buddy!
i just reverted to stock using the later NAND backup, V21E.zip , then the LG upgrade tool recognized and flashed without errors, tho before I restored to stock it was giving me some errors in very poor english.
Revert to stock -> LG Update -> NVFlash CWM -> CM Nightly = GPS works! FINALLY! I haven't been able to use my GPS on pretty much any rom til this point.
I definitely vote for the go ahead, the new baseband makes a difference for sure!

Fixed thanks and great info so far kiddecks have you noticed any issues with your data signal? the gps is not a feature I will be using a lot my main focus is on reception and data.

Don't forget to remove CWM as part of reverting to stock. You don't want to give the lg tool any chance to brick your phone like its doing for some people.

Thanks for that I will make sure to remember did you update your Baseband heysharon?

Not yet, the ota is either being dodgy or slow to come by, and I can't get the lg tool to install on my computer. Until the ota arrives for my phone, I'm hoping for the off chance that someone will upload the new baseband.

ok thanks for all your help from the sounds of it you also want to try out the new Baseband

Was wondering if anyone was still working on making
a zip file of the July baseband? I'm sure it would be much
Appreciated by many here. Thanks

and how can i remove cmw?

Do mean clockworkmod recovery? If you want to flash back to stock recovery you can use the one click nvflash tool from the development section. When you're at the step where you choose which version of recovery to flash just choose stock.

I really dont understand the question as to why would you downgrade basebands?

Gingerbread is the "stock" rom now. If you need to return your phone T-Mobile and LG fully expect you to have the Gingerbread update on it. There is no reason to return it to Froyo. Plus the baseband cannot be downgraded or even upgraded on this phone outside of an official OTA from a carrier or LG, through the LG Update or the KDZ method which invokes the LG Updater.

Need Help: LG Optimus One P500 [ROOTED]: Unable to flash custom ROM ICSLunarPro 2.4.6

Hi All,
I had flashed my LG Optimus One P500 with Stock ROM + Custom Recovery with the help of this forum.
I had also rooted my mobile and tried to install ICSLunarPro v2.4.3. Post Installation, I could see that the status bar is not appearing and the mobile doesnt recognize the mobile network GSM/3G. Even the media such as mp3 and images were not recognized in the respective applications.
Below are the details about the issue:
Mobile: LG Optimus One P500
Current ROM/Firmware version: V20C + Custom Recovery (CWM)
Android Version: Android 2.3.3
SD Card Size: 8 GB
Custom ROM: ICSLunarPro v2.4.3 (to be installed)
Link: http://forum.xda-developers.com/showthread.php?t=1408952
I would like to know if this problem is due to baseband version compatibility issues. Please let me know your opinions on this. Even I had installed another ROM (ICS Themed with Android 2.3.7) which had the similar issues like this as well.
Thanks!!

You certainly have a new baseband, if you want to flash ROMs which support only old baseband you must revert to old baseband first.
Otherwise if you don't want to play with your baseband then there are other ROMs available here built over v20 platform.

Is it possible to upgrade the baseband according to the ROM or it would make some serious problems due to mobile network?

My phone has the latest baseband (v20g europe) and i have recently tested some CM-based ROM's without flashing the old baseband. The rom's work perfectly and you simply do not have GSM or data connection (wi-fi works though). If you are having problems with a ROM, they are very likely caused by unclean partitions: make sure to always do a factory reset, wike cache and format /system before applying a new ROM via zip file.
bye

I also flashed the new ICSLunarPro 2.4.6 with the New Baseband v20G(Used an guide on here to switch to it when I tried an Gingerbread ROM for an while.) I didn't realize it was an v10E baseband ROM, but the ROM still installed correctly and all. I did an switch of the baseband after and service worked when I did so but the dev for ICSLunarPro recommends an complete wipe/reinstall for it to work correctly.
What I would suggest doing, go into your recovery(i recommend CWM Recovery) Wipe Data, Cache, Dalvik Cache, and Battery Stats. Then Flash ICSLunarPRo, wait for it to boot, change the theme with Theme Chooser to either Ice Cream or LunarUI, then go back to Recovery, apply the Patch he posted for 2.4.6, then it should be set. Resetting the Dalvik is very important if you had an ROM running before hand, I think you skipped that.

You need the old baseband fix. Search the forum and you will surely find it.
Nexus7/ParanoidAndroid/MKernel

Good.. you didnt create a new thread for this.
There are only two types of baseband in LG P-500.
New Baseband.. " v20 c/d/e/g etc "
Old BB " v10 c/d/e/h etc".
As FitAmp said.. nowadays all the roms are made for NEW Baseband.
You can either upgrade Baseband using various methods or use a temporary FIX.
Flash the first link in my signature below AFTER flashing any rom.
If you arent able to flash the fix.. normally unzip it.. paste it in /system/lib using rootexplorer. Set right permissions.

Thankyou so very much.
I am getting signal now.
However WIFI Tethering has stopped working, but dont makes a big difference....
I am heartly thankful to you for your kind support..

i think the baseband verion stays the same regardless its rom base. So L6260_MODEM_01.1042.00 will always show. To make sure its changed flash KDZ 21A, 21B, 21D Base Bands Roms Comaptible
All except Go to first new post
[ROM's][KERNEL's][GPL][REF's] The Promethius Project V1.4 [V1.5 Kernel 3rd Beta Test] IF you flashed either 21A,21B,21D and use Kernel 1.3+ You will have the no signal issue you mentioned .
To conclude if you planning on using Go to first new post
The Promethius Project V1.4 + 1.3+ or any other 21e based rom KErnel flash 21e.kdz you shall have no signal issues. IF rom not 21e base use any ginger basedband except 21e base

Updating my p509 from 2012/2013

I purchased an Optimus T (P509) in 2012 and had it unlocked to use on a trip I went to europe. I played around with it a lot and messed with custom roms and basebands, and then left it alone for about a year. I'm now downsizing my phone/tech collection in general and looking to update this to use as a daily driver.
Here's the info about my phone:
ClockworkMod recover v5.0.2.0
Baseband: LGP509AT-00-V10l-OPEN-COM-OCT-23-2010
CyanogenMod version: 10-20130108-UNOFFICIAL-p509
Build number: cm_p509-userdebug 4.1.2 JZO54k eng.arjen.20130108.030427 test-keys
My questions are:
What updates to baseband (if any) do I need to do? Would this mess up my unlock?
Do I need to flash a new recovery?
What ROM would be best for my needs as a daily driver? requirements are stable without crashes and everything works, followed by the newest android version.
Really the rom part I can experiment with later, I'm just not sure if I've hosed myself with the baseband 'fixes' that I recall messing with 2 years ago. I have a new sim card on the way that I will use with this.

1 - Actually upgrading baseband on that device would lock you out of some frequencies the radio ( not the FM radio ) uses to communicate with the carriers towers. I also have a Optimus T ( P509 ), tho no longer in service.
2 - Depends if you want KitKat ( 4.4 ). If you do then you'll need CWM 6.0.4.4 or newer. I am currently working on a utility for older CWM versions to be able to install KitKat but until then you'll need what I just mentioned. If not too interested in KitKat then you can leave your recovery as is. I use CWM 5.0.2.7 Touch by @vivekkalady. I've been using her recovery since she introduced it.
3 - You'll have to search and make that decision for yourself as we all have different needs and habits.

That's interesting what you said about the current baseband, I'm not sure if I changed it after I last used it. But I turned off airplane mode and popped in a T-mob sim and it wasn't able to connect to a network, similar results with H2O wireless card (at&t mvno). I'm not sure if my current version of android is messed up or the baseband.
I don't mind upgrading CWM, is there any downside to doing so? Is there a kitkat build out now that works? I may want to use KitKat as I hear it's meant to be more usable on smaller memory systems like the p509.
I don't mind finding one I like eventually, but looking for a recommendation to start off with that should work without too much difficulty.
Thanks for you help so far, I hope if can figure out this cell network problem :-/

Either your APN settings are wrong, which you can manually fix, or you did upgrade/downgrade/change baseband. The P509 is supposed to be an old baseband phone. The P500 and P509 are identical. Only difference is the P500 is a new baseband device. You can flash a P500 ROM. If you don't get any signal, then most likely your on old baseband. There is a patch for that, no biggie. If you do get signal then you're on new baseband and you should continue to use P500 ROMs. If you decide to flash a P509 ROM you won't have any service which will be a baseband issue. There is a new baseband patch around here somewhere too.
You can find a link to the old baseband patch in the LG Optimus One FAQ. Post #8 or #9, I think.

I wasn't certain what my starting point was since I'd done this so long ago (and I thought I applied the old BB fix at some point too...). Anyways, I took a drastic step and installed the stock rom V10s_00.kdz with the kdz installer from LG. It successfully flashed and I don't have a brick on my hands
The problem is now the phone doesn't recognize any sim cards, of which I've tried 3: tmobile micro, h2o micro, and a gophone minisim. The microsims were put in a cut out minisim as an adapter. The gophone is a normal minisim that is uncut, but it's not activated. I never got a locked or bad sim message, just that there is no sim card in place.
Under phone status it shows a signal strength (varies -65 to -75 and 25 asu)
Under APN settings it matches the T-mobile ones
And the baseband via secret menu is amss6038
I'm wondering if the sim module or gsm module are messed up? I kinda want to try out the emergency calling but would rather not get the police involved

I messed up my SIM contacts when I left an adapter in there and pulled it a little too hard out! I removed the compression plate on the back and it works again. I'll have to get a small piece of electronic safe foam to apply pressure to the back of the SIM to keep it in proper position. (http://forum.xda-developers.com/showthread.php?t=2598308)
I'm interested in the kitkat build here: http://forum.xda-developers.com/showthread.php?t=2589303
If I were to want to use that, do I need to flash the baseband fix on top of the other install instructions? Anything special in terms of timing it at a certain point in the install process?
Thanks for your help so far, I forgot how much fun messing with android was :laugh:

Well, we still aren't sure if your device is new or old baseband. With the recovery you already have, flash CM10.1, CM10.2, or CM10.3 ( All JellyBean ). Latest CM10.2 builds can be downloaded here. Easiest way to work around the baseband thing is to figure out which ROMs, P500 or P509, that will give you cell service. Flash a P509 ROM. If no service then you upgraded baseband so you'll need to use P500 ROMs. Flash a P500 ROM and if no service then you're on old baseband and you should use P509 ROMs. Only difference between P500 and P509 ROMs is the P500 ROMs are NEW baseband and the P509 ROMs are OLD baseband.
As of now the only KitKat ROMs being build are for the P500. If you find you are OLD baseband, flash the oldbb fix from the FAQ I mentioned a couple posts back. Oh, and you'll need the newest CWM 6.0.4.4 or newer recovery to flash KitKat.
Hope all this helps...

Well, I'm on the old baseband, the reason I know is I used KDZ to nuke it back to p509 stock! The more I read about kdz after I did it the more scared I got, but I lucked out and everything is fine now
The sim unlock is preserved, and I successfully rooted it with gingersnap. I don't have any sort of recover on it yet, it looks like CWM 6.0.4.4 does not work with older roms, just Kitkat based ones. So I'll do some more homework and figure out if I want to jump right into KK or try JB first.
Thanks for all your help, you gave me a quick jumpstart and brought back a lot of knowledge that was tucked away in the back corner of my brain!
