Ok, I know there are a lot of threads on these topic and believe me i have spent a lot of time reading multiple threads and the end result is i am not sure how to proceed , for my particular froyo version so I am posting it here hoping some Kind soul will help/suggest me on installing Cyanogen mod 7.
So here I go.
I have an LG P500 model phone with Anroid Froyo 2.2.1 (Software version V10c-DEC-08-2012, Build number FRG-83, KErnel 2.6.32.9 ). After trying several ways finally I have rooted my phone successfully. after making a clockwork recovery of my custom ROM, I proceeded to install CM7 Stable (for P500) using my 2GB memory card with 200 MB free space, it did not succeed and got stuck with the CM7 android logo.
I cleared up my memory upto 450MB and proceeded again by deleting cache/data and installing CM7 stable. This time it did install but i lost the IMEI number and the phone could not detect any network. I got the same result when i tried CM7 RC-3 . being unable to get a working phone I have reverted back to my custom rom using recovery.
After reading so many threads about these issues, i feel that this is some kind of basband problem as mine version is V10C, Can someone please help me how to install CM7 without loosing my IMEI and netwroks. (a step by step approach would me most appreciated). Thanks in advance.
Yes you need to upgrade your baseband to V20, there are several tutorials (step by step) on how to upgrade baseband on this forum.

Thanks for the reply, but do i need to install the new baseband after flashing with CM7 or prior to installingCM7, Please clarify this. as I dont want to get stuck again.
cm7 roms are new bb. u need to upgrade to v20 b4 flashng cm7. u can do it using lg pc suite or kdz updater.
Solved
I followed
tried to install V20 using this http://forum.xda-developers.com/showthread.php?t=1217504 which i found from here
I followed the steps in the thread but nothing noticable changed after doing it.
Thinking it had worked somehow I Flashed it now with CM7 but sadly nothing changed and my phone still did not had any network or IMEI even now.
I followed this http://forum.cyanogenmod.com/topic/44849-My-experience-rooting-and-ROMing-the-p500-on-Android-2.2.2..... and flashed using oldBBfix_signed.zip and whoa I got my network working again in no time.
Thank you guys for your reply and special Thanks to the people who made the threads that i have added above. :good::laugh:

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.

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'm not sure if this has been covered in another thread, but I was looking around a bit and found nothing and sorry if this isn't the correct place. I wasn't sure.
I have an LG P509(TmoUSA). Yesterday I rooted it for the first time and installed CM10 on it via ROM manager. After it successfully installed, I noticed I didn't have any signal and that my imei was missing. It said "Unknown" . On my dialer I pressed *#06# and a little box popped up with nothing in it. I switched back to stock rom using LG tools and both my imei and signal had been restored. I attempted it again but this time, I tried installed CM 7 via the ROM manager along with Google apps. The same happened. I again, restored back to stock. I attempted it a THIRD time, but, this time I did it via clockwork. I cleared cache and data and installed from zip. I installed CM 7 and CM 10 though this method. Both times my imei was gone and my signal was as well. Right now I'm sitting with stock rom and rooted.
Does anyone know what's going on? Can I not install custom roms with my phone without loosing my imei?
I think you did not upgrade your baseband, thats the only reason you are not getting signal. I cant tell about p509 but i had the same problem, but my phone is p500. You have to flash v20 baseband for new roms i.e higher then gingerbread search the forum i have a link but its for p500. Not sure if both p500 and p509 baseband are same anyway here is link for p500 baseband, just ask if both p500 and p509 baeseband are same if they are same you are good to go.

I had the same issue but with cm 9 and upgrading to the new baseband fixxed it for me
Thanks for the replies guys. I was in the process of upgrading the baseband, but I fell asleeping during the back up. I'm doing it now as we speak though. :good: I will post results.
It did work! Upgrading the baseband worked! Thanks for helping me out My IMEI and service as came back.
..and by the way, I think P500 and P509 are the same.
Hi all,
Flashed a new ROM for the very first time and I guess I've screwed up something.
I flashed the stable version of CyanogenMod 7.2. Everything seems to be running fine EXCEPT my sim-card is NOT being detected!
Cant find any network. Also the new ROM has completely wiped out my IMEI no. (That could be the source of the problem, dont know.)
Also, I really dont know my current or previous baseband,, err newbie!( maybe thats the cause of problem)...
Pls somebody HELP!
PS. my phone aint carrier specific and was earlier running on 2.2.1(if it helps )
Baseband problem, you was on a Froyo (10b-e) baseband, CM7 requires the 20G baseband, restoring a Nandroid should work. If you haven't got one. Then you will be using the LG flasher, good luck!
There's a baseband fix script lying around the forums somewhere that should allow new baseband ROMs to work for you. Search for something called "bbfix", or something like that.

Flash it in recovery and see if that works
Hi there, I have been trying for countless hours to make a custom ROM work on my P920 with no results, always some issues. I've managed to brick my phone in different ways a billion times now, then spent billion hours unbricking it and in the end I'm always back to where I started. I would really love some help please.
My phone is P920.
The android version I'm running is: 2.3.5
Kernel version: 2.6.35.7+
Software version: V21E
Rooting method: megatron
Now I would like a ROM that uses Android 4 and that can still use the 3D features such as 3D camera, the ROM calledthe Darkroom International would be an example I imagine.
While that's one of the ROMs that I would want, I've tried many, and always encountering issues, let me clarify.
First of all my device has to be rooted and since SuperOneClick doesn't work for me as it gets stuck on step 7, I use megatron which works well. I even double check if my phone is rooted with the Root Checker from the Android store. Now according to the guides I've read I need a custom recovery system, so I install Clockworkmod. I then place the ROM on the SD card, in the recovery menu I delete cache, that other cache, format it, format system, data, everything those guides tell me to. Afterwards, I install the ROM by selecting the zip and then I reboot. I've tried like 3 different ROMs, jellybem, cyanogenmod and some other. Yes I know none of them support 3D features - I didn't know at the time. Anyway, the issue was always the same, right after the LG logo there would be a screen with some weird colors showing the display of what happened before the phone crashed. Before it crashed? Yes, the phone would actually boot into the ROM but only for a few minutes, crashing afterwards. The next time I would boot, it would show that weird screen with those fancy colors with what happened just before it crashed. So I followed some steps and I got back to the original 2.3.5 ROM, everything back to normal.
I tried doing some more research and I came across the Darkroom Intentional ROM which had a bit different instructions. It asked me to install TWRP recovery with a bootloader, so I did, successfully, then did all the clean cache etc, installed ROM, bam, wouldn't boot at all. Oh boy have I had issues here, I couldn't even get it back to the default 2.3.5 stock ROM because my phone wasn't even recognized in the device manager. So I did some more research, found a solution, managed to flash back to 2.3.5 stock and I'm back to square one.
Now, could someone please help and explain to me what exactly have I done wrong and how I can make it right? I've spent countless hours now trying to install a custom ROM with no success. Sorry about the long read. If you need me to supply some more information please let me know. Thank you.
First of all if u want to use an ICS ROM then u need to update to ICS FIRST u can't flash it directly from 2.3.5 u can use xbsalls thread to update......
Next if cm based Roms are crashing then u need to flash bootloaders which means u should use os_hacking tool to flash ICS bootladers if u wanna update
Or flash GB bootloaders
So first update if u want
Root
Flash bootloaders
Flash recovery
Flash Roms

I've been running cloudyg3 2.1 for about 6 months and I've developed an echo problem during calls( on the other end) and I've noticed a lag both problems in the last week. I'm running 4.4.2, M8974A-AAAANAZM-1.0.190084 Baseband, KERNAL VERSION 3.4.102 BUILD KOT491 on a D801 . No other mods. I tried running backup from existing recovery but failed twice. I've redownloaded Autorec , the baseband version and CloudyG3 2.2 as per cloudyfa but haven't run it because id rather be a vagina with an echoing phone than a dude with no phone at all. Would someone mind giving me some advice? Could my problem be solved with a fresh install or upgrading to 2.2? Should I hold my breath for Lp? And could someone walk me through the steps?
I really do appreciate the help and I'll gladly pay it back .
Thanks

Are you sure that you don't have any tweak? It might be a ROM problem. I suggest you to flash the newest version of CloudyG3. If you have a problem with the recovery, is always good to have it up-to-date and then flash the newest ROM.
In my case I always had problems with the newest versions of Cloudy. I used to have it on my phone until 1.3 version and then the data did not work for me, so decided to go with Optimus G3 1.4.1, which was the last ROM I used in my LG G2 and everything worked smoothly. If you have the availability, give it a try.

Thanks. I appreciate the help. I found a video on YouTube with some guy flashing the exact same and it turned out fine.
I couldnt get it to back up using TWRP from the first flash of CloudyG3 2.1 so I used LG backup and saved it to pc. Then I flashed the Basrband for KitKat and CloudyG2 2.2 simultaneously. I beleive 2.2 to be the newest. Everything went through for the most part. All important data was there but I did have to reset up my contact profile and my display setting. also also the knock code does not consistently work. it didn't fix my sound issue but it did rerevert my camera back to what I had when I originally flashed G3 2.1. after that's all said and done, I remembered flashing a fix to repair the knock code on 2.1 and that's how I lost the camera in the first place.
anyway, everything's good . I stretched my G2 for an extra year without feeling like I had missed out on anything. I wonder how many others did the same thing. Cloudyfa may want to keep an eye out for LG ninja's. Thanks again.
