[Fix] No Signal / No sim detection on cm10 - Optimus L3, L5, L7 Android Development

Hello people of the XDA forum!
I saw many people had trouble with the connection of their sim card when they flashed cm10. In this threat i want to show you how to fix this issue.
Maybe many people already found a solution, anyway, in this topic i want to put the solution to stop people searching for it
What's the problem?​So, you flashed cm10 from v20(?). now you don't have a signal am i right? so how we gonna fix that? If you follow my steps, you will be able to have a signal after this all.

Or you can flash basebands via CWM
v20 baseband for Stock v20 Roms.
v10 baseband for stock v10 roms and Custom roms which are based on v10k (To this day, every single custom rom have baseband of v10k)
You can download them from my Googlde Drive. Here's the link: https://drive.google.com/folderview?id=0B_hs4HhjiC56MDREeFNzYnpZQlE&usp=sharing
How to use them ?
Instal CM10/MIUI/AOPK/SLIMBEAM/PAC rom to you L7, then flash baseband zip, which is v10 for custom roms.

Credits to the maker of the rom and the kernel and the flash tool etc i do not take any credits!
And remember! : Doing this all at your own risk!

If you have cwm, you can flash directly to cm10 or other aosp based roms like aokp, slim bean, etc. Flash the v10 baseband after the rom, then your good to go.

I think you need to add it manually or use SIM toolkit app to request for mobile internet and handset settings.

Hello friends.
I am trying to fix my Lg Optimus L7 for 2 days now, i tried almost everything on the forum and still i cannot get my network working. Here is what i did so far:
Installed the Russian V10k via KDZ - Not working, i cannot get signal again
Installed 10 other KDZ files that should have "worked" but nothing
I flashed back v20a and i have network, then tried again to downgrade again no network
I Installed slimbean (when i am on v10k) and flash the zip v10baseband.zip - again no network
I get phone sim locked, network locked
Please help me, what should i do?

i'm sorry but i'm new to this kind of problem and i'm getting nowhere to the solution
