[Q] After rooting phone doesn't connect to any gms network - Optimus One, P500, V General

I am completely new and did my first rom today. Seems fine but the phone doesnt ask me for the pin number for the sim, as it always did. And when I try searching all gsm networks it returns me an error.
Well just also need to tell you that I am using roaming for I am in another country then the one my phone and gsm networks are from. Can someone help me»

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?

Missy:
- there is NO mik baseband. There are LG v10 and v20 basebands.
- The only thing from mik related to baseband are patched ril libs for CM7 that tried to make the new baseband working on CM7 and failed, since it cannot read the operator information from SIM card. Therefore, no APNs and no 2G/3G.
- There is an extensive howto I have written with instructions. I have also explained in detail which baseband is for which ROM.
Read the darned howto and stop asking the same thing over and over again. If you do not understand, stay with stock ROM.

Flash the goddamned old baseband as said in my howto. Then go and reflash the ROM. It is clearly said that the patch does NOT work for data on the mik's thread, why are you flashing something with a known bug and complaining thereafter?!?

Because you need to reflash the darned ROM which you have screwed with the non-working patch. Read!

plz gimme a link of ur kernel version
RoM n baseband
Well, flash a full stock ROM via KDZ and move on. When you have done some reading (which clearly hurts your brain), come back with some non-PEBKAC issues. While you have mismatch between your baseband and ROM, you have no GSM and data. It is written in the howto, but then again, too long and boring to read, huh?
Bye.
Hello ppl. I have flashed to new baseband w/ Cyanogenmod 9(lurpohip) and franco's newest kernel. I can call and send text messages, but data doesn't seem to work. Would appreciate help. I've gone through both how-to's pt. baseband LGMDP.exe. Also did a full data wipe before installing the rom.
I noticed some NVRESTORE NV_FAIL_S errors when I changed to new baseband in LGMDP.exe though.. Any ideas? Tried to change 3 times, same errors occur.
Thanks in advance. Sorry for being a noob, but I have been searching for 2 days.
Unfortunately, CM team has removed some frequency from sources and now, with some carrier (eg. Vodafone or 3 IT), data connection doesn't work. I have the same problem. The solutions are:
1. Not use a CM rom
2. Use old baseband with patch for CM.
3. Wait for a fix

[Q] imei number wiped when installed new ROM

Hi all I am having problems flashing a different rom to my lg optimus p500h. I have tried flashing a couple different roms to my phone but when I boot up I don't have service. I looked for my IMEI number on my phone and it's blank. How do I flash a rom and keep my IMEI number?
possibly you dont read carefully what roms you can use when flashing this phone.
there are 2 sorts of baseband (needed for gsm and data service) - if you are coming
from LG stock rom you have to decide what rom you want to use and than you have
eventually flash the baseband too... its all written here in general topic, so take a look
at previous posts/topics about baseband and what rom to use.
What would be considered the stock rom? It used to have 2.1 on it but I updated it a couple times and it now has 2.33.

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.

no 2g after flashing adfad666's cm 7.2 with telus p500

im guessing i cant get 2g because telus's 2g was cdma? im on the old .32 baseband and flashed that version of cm7. does anyone know where i can get just the radio or baseband for telus to flash over this rom?
this is my pay and go phone so i dont need 3g data and 2g gives me better reception and battery life so i want to be able to leave my optimus on 2g all the time.
EDIT: i just tried flashing P500-v10E-baseband.7z from this thread and have the same results
u had to change the rom, not the baseband....

From what I gathered in the abandoned thread for AdFad666's rom, future builds may only exclusively support the new baseband.
Of course, I could be wrong, since it seems like the A-series and F-series are still being updated.
In any case:

OP, did you confirm that you're on the correct baseband?
You can either throw the phone back on LGMDP (it'll display a version in the window) or hop down to a rom that has the LG hidden menu.
Also, what happened to the backup that was made when you flashed to v20G?
