[Q] LG P500 help!

I am not a pro at installing android os. I am 16. I recently installed Cyanogenmod 10 (Android 4.1) on my phone (LG Optimus One) and I can't call. I use Simple Mobile. Whenever I try to call, it says,"Mobile Network not available". If you don't know a way to fix this. Can you show me how to put it back into Froyo 2.2?
Seems you are on old baseband and you have flashed a rom which is based on new baseband. Just search for ' old bb fix ' and flash this from your recovery. You will get back your network.

Nvm, I got it. I have the same problem for the Galaxy S2 model t989 too. It dropped in the water, then it can't read the sim card. So can you give me a link to old bb fix for S2 T989 plz? Thank you.
Ok, apparently, I installed a different old bb fix and now that doesn't work , then I installed the one you gave to me but then it didn't work. So I am stuck again. Please help.
goto settings, abouth phone and read what is your baseband, if it's v10 that is old, if its v20 it is new,
if it is old update via LGMDP to latest version 2.3 GB(if PC doesn't recognize your phone, boot into recovery, conect usb cable an from advance/mounts mount usb), install, reboot, now you'll have fresh oficial GB, root with Superoneclick latest version(maybe you will need to do it few times, for me it didn't go first time, if I remember it was at 3rd time or so), install CWM trough RomManager and after that you are good to go with what ever you want to put in that phone, anyway, all ccustom roms from 2.3.7 are for newbb

[Q] Boot loop

Hi guys,
My son of 9 wanted a telephone so I bought him a LG P920 3D because I can't afford a new one now. I wanted to install CyanogenMod cm-10-20131006-NIGHTLY-p920 and gapps-jb-20121011-signed. I have done it before with my own phone (S3) and tablet (TF101) and that went just fine.
Now with my son's phone something went wrong. It's now only showing the round CyanogenMod logo which keeps spinning and nothing more.
I especially bought ClockworkMod Touch Recovery to flash it with. Please help me because my little boy is very dissapointed and he got a present, a car you can control wireless with a phone and that was the reason why I wanted to flash it. So he could play with his new toy.
I did a factory reset so I started flashing with a clean phone. Please help me!
First install ICS V30A baseband use this video (you may need to go in to the stock recovery after flashing and do a factory reset is a problem arises during flashing)
https://www.youtube.com/watch?v=FqC5qw6WRaY&feature=youtube_gdata_player
secound install WKparts bootloader and TWRP you can use a tool om this forum named simple tool can be found here everything you need is in the tool
https://www.dropbox.com/sh/p959msww1ol04s4/BUlrkRLEs7
and then load a rom on to the external SD card and flash it in TWRP or CWM touch i recomend

if you want the newest CM although it's a bit more hassle with this 4.2.2 pacman rom as you need to delete the first line in updater script for it to work properly on ICS
@sioxz
thanks for your response but after a while I found out that I had to hold on the volume down (and not up!) + power + 3D button. I've read somewhere volume up so ofcourse nothing happened. Finally back in recovery I could flash again another rom and that went fine. But now I have another problem and that is I don't have a baseband version.
So no 3G!! What do I have to do to get a baseband?? I really have no idea, I've search everywhere but I couldn't find anything.

This what I have flashed:

CyanogenMod versie
10-20130908-NIGHTLY-p920
Build datum

Buil-nummer
cm-920-userdebug 4.1.2 JZO54K eng.

i don't know where you can flash only the base band but the V30A haves baseband in it and it makes to that you have to flash the custom bootloader which works really good (can boot anything)
You can flash baseband with LG Flash Tool.

Can you please tell me how, step-by-step. I've read some tutorials here but they are so not easy to read because they always use so many different colors and fonts it becomes hard for me to understand what they are saying.
Mine is about as clear and detailed as you will find

BUT AFTER FLASHING IT I HAD GSM CONNECTION PROBLEMS
SO BACK TO STOCK ROM AGAIN
BUT THIS TIME WHEN I FLASHED THE STOCK ROM IT GOT STUCK AT THE SAMSUNG LOGO
I COULDN'T GO INTO RECOVERY MODE THEN
SO I CORRUPTED THE DEVICE AGAIN AND INSTALLED THE STOCK FIRMWARE
