Question about baseband upgrading

I use to be on V20C and decided to switch over to V21E to see if it will help with ghost call issues. I got everything working. But I noticed my reception is on Edge now. Is there anyway to fix that or is that normal cause I switched basebands? I use to be with Rogers on V20C in Canada

i need some advices on that problem too phone works but no data network (4G in my case its always "E")

need help please on that one

Not possible, V21e does not support the required bands. Try v21f.

It dosnt work for me lol cud that be because itts still on froyo maybe it says i am upto date with updates
Sent from my LG-P920 using xda premium

Froyo, yikes. Update to gingerbread with kdz method asap. Froyo is slow and battery drain was diabolical.
Ignore the "no updates" rubbish, that's just your carrier who can't be bothered to give you any.

You are mucking up the forums with questions that have been answered over and over. Please use the search button. I think it's one of the rules (or at least it should be). Everything you need to know is in the dev section. Reading will make you more knowledgeable about your phone, its capabilities and this entire forum.
Good luck rooting your phone and trying new roms.

Sorry i just dont seem to get the right response when i post in right place for some reason. But i will do it from now on.

Good that you have rooted successfully.
21E baseband is the one that doesn't have the :GHOST CALLS" issue.
ROMs are sensitive to the baseband versions, so please be careful about te ROM you are trying out else you will face no network / boot loop / stuck on LG screen.
If you can flash Baseband 21E, then Promethius ROM 1.4 with Promethius Kernel v 1.4.5.1 ( please check for kernel versions with + and without + in the end) will give out the best battery life (as per my experience)

All the best

Ive tryed that rom a couple of time twice had no network signal and once stuck on lg screen bloody pain. I thought it was coz i was still running froyo but since on gb still wont work and for sum reason it wont flash the kernals all a bit of a blag for me so just on rooted stock rom now lol
Sent from my LG-P920 using xda premium

You must be on GB and baseband 21e to use latest prometheus roms, and kernels.I think you can use Prometheus 1.3 rom with 1.3 kernel, and you will have signal.

Hi after downgrade back to gb bt doesnt work. It wont even turn on.
Edit: im on stock v21e + v21e baseband. And ihave flashed bernis files to get rid of that korean download mode. Now i cannot enter it to check if its gone lol.

So far i have tried v21A ap, v21e ap. No bt. Cm10 too. Does lg update flash something more than flash tool? I have converted kdz to bin files.

Ghost call on cm10?

Hi to all,
I am just wondering am I the only one that have GC on CM10?i am using v21e with bernies files
Thanks a lot

Probably you're the only one , i don't have ghost calls.
Using V21E baseband.
You need to be in V21E to eliminate ghost calls so , be sure you're on it.
Download the app GETRIL from playstore , it'll show you which baseband you're on.
But flashing v21e baseband from the start takes about the same time so , you might wanna just flash it again.
Ignore the build.prop line.
Flashing a new baseband won't modify the build.prop so it will stay as it is.
So if you flashed V21E while installing CM10 or any ROM and then V21D or something accidentally , it'll say you're on V21E , which is not accurate in this case.

That is strange,i have only been on v21e because all other roms suffers from gc issue.recently i upgraded to cm10 directly over 21e and now i know two persons that have call me and my phone did not ring!

Just right now my friend told me that he call me today two times and i did not answer!ahh crap
Sent from my LG-P920 using xda app-developers app

I confirm it's true, as I have warned about this quite some time ago.
Tested by a friend with 3 different basebands, 21A, 21D and 21E. He is currently testing 21F.
All present ghost calls and at least one of them had also ghost sms'.

And 21f is good so far?i suppose i must return to stock 21e to avoid gc issues?
Sent from my LG-P920 using xda app-developers app

He has only been using 21F for some days, so still too early to say.

[Q] (Possibly) bricked optimus 3d

So I just installed CM10 nightly ( jelly bean if I'm correct ) and I think something's wrong. When I try to boot it first thing that looks wierd is random colors (shouldnt be like that). After that it boots up after loading and I can use it. After using it for 2-3minutes it just turns itself off and I have to take my battery and put it back in to get it working again for 3minutes. How do I fix this, I am sure I did nothing wrong.
Edit: I installed it over CM7 nightly, I think it might be because I didn't wipe caches, but now I dont have rom manager.

Are you on 21e baseband? If you are. That is your problem. Just change your baseband

You have to read a little before you flash your phone... you need your baseband for right communication eith phone. If you want to flash baseband you need flashtool. The files you need are fls files. I consider you to go back to cm7 for now and to read few tutorials, so you have enough expierience to flash cm10. Cm10 had a lot of bugs because its the nighly version. And for most people they need to flash bernis files and wkparks bootloader to get cm10 working.
