Here's a link to where you can read more about getting the new baseband:
http://forum.xda-developers.com/showthread.php?t=1140862
BUT! for trying out CM7 on your phone you currently do NOT need the new baseband, although you might need it in the future.
All you need to do is install ROM Manager from the market > flash custom recovery from it > download the required files and follow the instructions available here:

Hope that helps

What about gsm.what is gsm?
Sent from my LG-P500 using Tapatalk

GSM = Global System for Mobile Communications more or less your phone's ability to work as a phone/connect to your provider's network.
The tricky part with basebands and different ROMs is that once you flash the new baseband (update to official GingerBread), you will not have gsm/network if you go back to a ROM based on the old baseband. Up side is, Mik has taken care of it by coming out with a workaround, which you can find in the FAQ section in the CM7 link I posted earlier.
And btw, searching the forums is a good way to find a lot of useful info, don't get me wrong, I'm new here too, but all the answers I'm giving you, I've managed to find with the search options

Ok thanks dude this is very helpful

What was your previous ROM and what is the one which you flashed today? And are you getting any networks in the search? If yes, is your home network available in the list?

I had the default rom and now moved to void #forever - and it doesn't show any network at all, when I do a search it always returns network error and it never asks for my pin. Thanks for the fast reply people
And the default rom was what? 2.2.x or 2.3.3?

Which version of Android did u have on your phone before you rooted and flashed a new ROM? Which ROM did u flash?
If u had Froyo (2.2.*) and now u flashed a Gingerbread based ROM (2.3.3), you have a baseband problem (The baseband is the subsystem of the phone that controls radio communications: GSM and data connection...). Froyo uses a different baseband (old) than Gingerbread (new baseband).
Solution: change the baseband according to your newly flashed ROM.
How to upgrade/downgrade baseband for noobs
Flashing baseband (radio) via LGMDP.exe
If u have a Froyo based ROM or any ROM that needs the old baseband (Mik_os's CM7 port...), you need P500-v10E-baseband.7z
For Gingerbread based ROMs u need P500-v20G-baseband.7z
--------------------------------------------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------------------------------------------
EDIT:
Since u came from Gingerbread u have the new baseband. Since #forever is based on CM7, it uses the old baseband... U need to downgrade to P500-v10E-baseband.
Has I said I am a rookie but what I did was:
Installed original 2.3.3
- Rooted
- Created recovery
- Installed latest Void #forever
GSM didn't work

Dude, you had 2.3.3 first. It uses new baseband.
Void forever is based on CM7, which supports only old baseband.
You can do any one of the following things:
1. Flash 2.2 official ROM through KDZ. So you'll get old baseband again and you can install void forever. Go here: http://forum.xda-developers.com/showthread.php?t=1060121
2. Mik has a fix for the new baseband. It will provide GSM support, but internet data will not work. Wifi will work, GPRS/3G will not. Go here and flash the file through recovery: http://www.multiupload.com/R9CEDO2HS9
3. You can revert to the old baseband. Follow this thread: http://forum.xda-developers.com/showthread.php?t=1149530 and you can find the old and new basebands here: http://lg-p500.zrusit.eu/index.php?dir=baseband/
Follow the steps in the given threads and you should be fine.

It gets easier as you get more "seat time" with this stuff.
I'm running Mik's stable at the moment and I'd say it meets 95% of my needs. Great ROM.
also dont forget to look into the available kernels, they are preety much what makes your system what it is concerning its speed, graphics, battery life
the current mik_os and void both have outdated versions of the franco.kernel, and a much more recent version is available, as well as a modified version by fserve.

I have flashed the new kernel, thanks.
Honestly I am very thankful for you guys being so nice. Sometimes I see in the forum some really hard messaging towards the new guys and I think we all want to learn right?
So my biggest problem with the phone I love P500 was that it was a bit laggy and although I moved apps as much as I could to the sd I was running out of space in my rom.
Now the system is a lot faster and although (because I am a noob) I lost some of my stuff I am glad because the phone is working so much better.
Actually I have another question: I bought Titanium backup because it seemed really worth it (it is the only paid app I have) but when I look at all the possible apps to backup there seem to be a lot missing (all the ones in the sd card).
Does anyone now how I can fix it?

newbie. best rom?

hi i just bought my phone last week an I've already experienced some lag even though there's not much apps installed. so now i want to try a custom rom. what rom would be the best for first timers thanks..
If you have 2.2 installed (old baseband) than andy's phoenix rom is the best.
Grab it from here http://forum.xda-developers.com/showthread.php?t=909242
If you have 2.3 (new baseband) than you should go for Ginger LOL:

hi, thanks for the reply. baseband is the version of android im currently using right? im using 2.3.3. but the link for ginger lol says page is not found. i'll try to search for it in the forums. thanks.

baseband is not the android version. i wrote up a small thing on baseband here.
here is the link for ginger lol (the link in post two is actually the right link except for the four dots):
http://forum.xda-developers.com/showthread.php?t=1118685
in my opinion, i would use andy's phoenix rom. follow these instructions:
a) http://forum.xda-developers.com/showpost.php?p=15309588&postcount=2
b) also, since you are currently using official gingerbread (2.3.3), you need to downgrade your baseband version, instructions found here
thanks for the info man. as i've read, most roms will eventually support the new baseband. so i think, im gonna wait a little longer for that. one more thing though. i though when i install rom, the kernel comes along with it, but as i read it seems that i need to flash my kernel too? thanks for your help.
phoenix rom comes with franco's .35 kernel preinstalled
There's no need to install other kernel.
roms using old baseband is never going to support new baseband...
DUDE I prefer, no need to root your stock rom for installing custom rom.
follow http://lg-p500-optimusone.blogspot.com/ if u want this.
note : I didnt try this but this should work

[Q] Can't Save APNs in Custom Roms

hey XDA peeps,
Seasoned Android modifier here.
Got a LG Optimus One from Telus (Canada) (P500h), came with 2.3.3 .
I can root it, flash custom Roms, Flash the Baseband Fix, Flash a custom Kernel and restore it back to Stock 2.3.3.
The only thing I can't make it do, is make my custom ROMs save my Rogers Wirelss APNs !!!
I can't seem to find a KDZ file for the V10 (2.2.1) firmware and two of us cannot figure out how to flash the DZ files, (Cannot Find Monitor Port?? Tried 2 different computers). From my understanding, its best to start from the 2.2 Software, but I can't find it for my P500h Telus Canada.
I see that I am not the only one who is having the APN Problem.
So what I'm asking is
A) How do I fix this APN not saving issue
B) Which CM ROM should I flash that does not have this issue
Thanks!
You have to downgrade your baseband to old one then you can save apn ...
Flash cm6.5.8 it is stable

So, i gather that the zip file ive been flashin via CWM called "baseband fix" is not downgrading my baseband.
Is this a file I have to flash via KDZ? Can anyone link me to the file? I've looked high and low for such a file.

Can i go back to the old baseband? Is there a thread somewhere? Is it safe? From my own investigation, it looks to me like I don't go back to the old baseband, but rather flash some patch to make the roms work anyway. Sound right?

It won't be OK. If your phone uses the "new" baseband, ROMs made for the "old" baseband will work on your phone (as in flashing will be successful, the phone boots etc.) and everything works except for the most important thing in a phone: the GSM/UMTS module. Which means you won't be able to connect to your mobile network and won't be able to make and receive calls. Bummer. Now, there's a patch that solves this BUT something will still be missing: mobile data. You will be able to make and receive phone calls, but you won't be able to connect to the internet using the mobile data connection (only WiFi).
So, if you want to use a ROM that clearly states it's made for the old baseband, old baseband is what you must have on your phone in order for both calls and internet to work. How to tell which baseband do you have right now it's a different discussion and we'll get there if necessary. I just detailed vlt86's answer for you to understand.
EDIT: I see you already know what baseband you have - the new one. Follow voyager20021's link in order to find out how to return to the old one.

Switching Baseband - The easy way [ Tested on GB ]

Mod plz add this to sticky or link it in sticky
As we know there are two types of baseband's available for our device, old baseband which is used by froyo and some gingerbread rom's and new baseband that is used by gingerbread onwards.
To switch baseband you either need to flash baseband through lgmdp or flash firmware using kdz and both involves a substantial degree of risk of bricking your device.
What I will be telling will not actually change your baseband but will make the ROM compatible with the baseband you are using. So here it is how it goes.
-> If you are having old baseband and want to use new baseband ROM, flash this after flashing ROM

-> If you are having new baseband and want to use old baseband ROM, flash this after flashing ROM
https://www.box.com/shared/r5l39a5ocaxr8zq1s46h
Note:- Patch for old baseband was originally made by adfadd and thats where idea came for creating a patch for new baseband. While the patch by adfadd is long lost in pile of threads, this is where this thread will come handy.
Flashing baseband through LGMDP cannot brick your device,only flashing full firmwares via LGMDp or KDZ_FW_UPD can have chance to brick

i looked into the zip file and found that a few lib files are added by flashing the patch. would this affect the performance? my phone works fine in 90% of the time. however, sometimes it is just too laggy to even answer calls. it could become normal after some time, say 30s ro 1min.
i dont have this problem when i was using roms based on the old baseband. so i am wondering what would the patch do to the system.
thanks.

those libs aren't going to affect performance in any way... its the ROM & kernel that affects performance.
