hello, just wanted to say on the prometheus project roms v1.3,1.4 and kernals v1.3,1.4, and 1.5 i get no signal. i can only get signal on roms version up to 1.2 and kernal 1.2, even after installing a new baseband still no signal, anyone out there with a solution to the problem?
Have you checked your baseband version with getril from playstore?
please hit thanks if i helped
yes its v20F
Have you flashed promethius 20f kernel to? sometimes it can take awile before it works.
please hit thanks if i helped
yuo, nothing is working, no signal at all, usually when i have no signal it will say emergency call only but when i flash kernel and rom, says no signal.

Download the v21e baseband from here

Then download the Attached v18a baseband from here

Read this for how to use LG flash tool
http://forum.xda-developers.com/showpost.php?p=17177547&postcount=2
Then copy the name of the v18a baseband file to the v21e baseband file u downloaded and flash it with LG flash tool (otherwise you get an error saying invalid cp path. the flashing proccess will say failed at 72s, when that happens, just exit it and turn your phone on. It should work now). Use a windows XP 32 bit pc.
i had the same problem when i flashed a baseband 2.3 and then a rom and no signal
i did flash again a kdz file 2.2 and woked fine
then a acura rom for 2.2 baseband and it is now super

Hey guys,
When I flash v21E I get no signal, any ideas?
Thanks
Same with me I think it has to do with kernel if I get some time I'm going to try a bunch of different kernels with 21e and see what happens
You have to flash 21e baseband or 21e kdz file with baseband included. Tutorials are on general section.

ya thats what i did i flashed 21e kdz and no network at all

Yeah me too, I'm not a noob I have written my own roms before. I am just nooby on this phone lol. I don't understand how with the correct baseband etc it still doesn't give me signal. Any help will be greatly appreciated.
It's really weird: I own a Brazilian P920H which should be incompatible with V21E, but it's not. It worked with the official ROM and now I'm using Prometheus 1.4 and Prometheus kernel 1.4.5.1 for a couple of weeks. Wonderful battery life and no ghost calls.

did it again
So I did it again ... after I installed the baseband I went into recovery and did all the wipes ... I got signal! let me know if it works for you.

I struggled to flash the KDZ file. When I got it to flash, I had a complete phone update to original GB. This wasn't so bad but I still wasn't on V21e. My PC is having all sorts of problems flashing the KDZ file (I've spent a few days trying to get it working) so I've moved on to the fls file instead.
I used SmartFlash Tool to flash the bin and fls file and although I am now on baseband V21e, I now have no signal. I have used GetRIL to match the RIL to the baseband but not joy. I have reflashed the bin and fls files a few times.
May be worth noting that my RIL says its V21e and my Baseband is XMM6260. GetRIL recommends V21d but it doesn't solve the problem.
I am now using the Prometheus ROM and Kernel but still no joy. I have tried different kernels, like the Titan kernel that has solved the problem for other people. Please help - currently my device is a 4" tablet
*Edit* - having more of a read, its possible that I'm using the wrong bin and fls files and maybe the XMM6260 chipset is not used in this phone. I'm going to try to find a different version of the fls and bin files - if anyone can point me in the right direction for the v21e files for the P920, that would be greatly appreciated
*Second edit* - I think the phone DOES use this chipset. Help please
*Third edit* - FIXED. I flashed the Titan kernel again (I flashed them all again) and reset the RIL to v21e in GetRIL and I now have signal, hopefully ghost call free. I should note that GetRIL says my RIL and baseband DON'T match
*Fourth and hopefully final edit* It wasn't as fixed as I thought. Some kernels gave me wifi but no phone signal, others gave me signal but no wifi. I'm now running blue kernel on Prometheus 1.4 and both seem to be working.
I really liked CM but it forced my baseband back and I was getting network issues, plus the lack of 3D caused me to change up. It did indicate that basebands could be updated through ROMs, which would make things much easier

This is happening because smartflash doesnt flash baseband properly...
You just got your signal back because of the kernel you flashed over... which isn't a v21e dependant.
I had the same issue...
Solution? I kept my v20a baseband and I'm using XPlay3d (which is based on v21d).
For me smartflash won't update my baseband no matter what I do... although it flashes the firmware and stuff (and even recovered my phone from a LG logo stuck brick)
That makes sense. I did upgrade the stock LG firmware first and ghost calls seem to be cured. The worst was being on froyo and using a GB ROM like CM7 - calls and data signal were horrendously inconsistent

I wouldn't recommend the blue kernel, it gets slow and the cpu gets very slow in responding after having the phone on for a few hours.
Try one of the older Prometheus Kernels, i had the described network problems too, i couldn't even enter the pin for my sim card.
I tryed a few kernels, and i found out that Prometheus V1.4.5.1 Kernel is working best for me, eventhough it crashes and reboots when you activate bluetooth, but wifi AND signal is working, which is the most important for me

I tried Prometheus 1.4 ROM but didn't work. I probably need one with a matching baseband. I have noticed my phone slows down after a few hours and eats more RAM - thanks for the heads up

Try the newest rom, it flashes the super stock kernel with it, at least should get a signal then, otherwise try a different baseband version (there are 2 different versions) Maybe you flashed a wrong one in the first place. Also the prometheus rom doesn't flash its own kernel, i would advice you to flash the real prometheus kernel, as soon as you booted with the normal prometheus rom, then reboot into recovery and flash the kernel. for some reason there are problems for me when i install a rom and flash a kernel right afterwards, without booting and setting up the new rom.
Also did you wipe everything before installing the rom?

That's what I did - I flashed Prometheus 1.5. Yes I wiped everything. I have an issue with my PC and LG Flash Tool so I'm trying to avoid using it again.
Just to clarify, you are saying I should flash Prometheus 1.5 ROM, then the 1.5 Kernel? There are two (one with a +) for different basebands I think. It wouldn't be a problem as I have everything on my SD card and ready to go. However, I'm not sure which baseband I'm on now - my phone says v21e but you are right that it doesn't seem to be

my phone showed the same, and the + kernel didn't work for me, i didn't get asked to enter my pin or anything, it was showing just no network
I was using CM7 by mik_os on my Optimus One and my phone was working fine. I wanted to try ICS on my phone and installed 4.0.3 by Lupohirp. Thats the beginning of my problems. Once installed, there is no reception on the phone. When i go to network operator selection, on manual selection of networks it gives error "Error while searching for networks" and when i select Automatic selection it shows "Unable to connect to this network at this time. Please try again later". I am sure i had wiped all the data, cache before installing ICS ROM. Hoping to correct this, i installed Oxygen ROM, but still the phone cannot get the signal.
Please help me. I m guessing this is something to do with the baseband/kernel..about which i dont know much.
Old Baseband(V10?) - Froyo and variants,mik's cm7
New Baseband(V20?) - gb and variants,ics and variants,oxygen,cm10
If you want to just try a new baseband rom flash the following fix:
New BasebandFix by adfad666
It is only temporary and you will have to flash it each time you flash a new baseband rom.
If you revert to a old baseband rom, no fix needed.
For a permanent fix use the following tutorial:
[HOWTO] Flashing baseband (radio) via LGMDP.exe - Flash P500-v20G-baseband.7z
Or(i prefer the method below):
flash gb(v20g) through kdz>>root>>cwm recovery>>flash cm9

Any help with this would be great thanxs.
You mean that your mobile running 2.2 and you install a costum rom (.zip) ??
This costum rom may be a gingerbread rom so you must upgrade your phone officially before flashing costem rom .

yes i can see my imei number
my base band is L6260_MODEM_SIC_01.1042.00
software version LG920-V20D-JUN-27-2012
android version 2.3.5
this is an orange based rom n would like to have it on stock
there is different stocks on different times (first was v10a)
this is not your base band This is INFINEON stuff.. go to market place and take GetRIL
Install. Run, See your base band version.
You can also isntall from there the recommended RIL for your configuration. Wait a minute (do not exit the program). if you do not have still signal - then RESTORE RIL back from the program (the program make a backup of you RIL when you install new one)
I've tried that getril and it said baseband matched but still no imei number once I've installed a custom/stock Rom. Looks like ill have to keep the orange Rom
Sent from my LG-P920 using xda premium
IMO getril is pretty useless and most of the time you're better off when they don't match.
Why are you uncomfortable flashing a baseband? Its not as simple as a zip and can be a pain but once you get it, you have so many more options.

Hi, i don't have 10 post on this account so i'm forced to post this here.
Just to say that CM10 nightly works fine with V21A Europe after some reboot. I'm downloading JB_Multi-Pack++ V3 for Gapps : WORKS !
I've just test 3G and Wifi. Bluetooth seems to be OK and GPS too.http://forum.xda-developers.com/showthread.php?p=33383098
P920 V21A EU baseband OK.
EDIT : After some hours and test, the BB disappears then i'm forced to re flash cm10. So, this nightly can't be used daily. No fully network. Wait a new nightly :fingers-crossed:

Can you tell if you were on ported ICS? And what you was running before CM10?
Although flashing with V21A or V21E, it always stucks at CM logo loading :crying:. There's also a strange pic after loading LG logo.
I was on Thiaiz 2.8 (V21E) -> flash to V21A Europe -> Flash CM10.

Same Problem as cm7 here! Just Reboot and wait a few Minutes and then search for Network! Happens about 2 times a Day
If you dont reflash when phone bug , it will reboot by itself ater a while then you have to pull out the battery and pull it back and the phone should restart with baseband recognized
im having trouble with the camera.. it force closes..
i was using cm7.2, the camera had 3D.
cm10 nightly dnt hav 3D photo nd video capture?
No, CM10 haven't 3D. But with Multipack++ Gapps you have the 4.2 camera app.
Btw, im' return to Thiaiz 2.8 V21E ^^ Keep in waiting a better stability
I tried to flash with many ROMs, but it didn't work. The phone just keeps loading at CM logo. Maybe I should flash back to GB and wait for st new :angel:
Where can i get the V21A Eu baseband? not the whole kdz file..
how to flash just the baseband to V21A Eu? (some .fls file)
is there any way?
The title is misleading since for many it still doesn't boot up. For the ones it do work for it either doesn't show bb, it may work without sim card freeze with it etc... This seems to more like a test rom than anything, now don't get me wrong I'm very greatful for the updated roms that lies good could never provide but I'm going to wait to a stable version or RC version to be released.

I had this new Optimus 3D (P925). I flashed it with CM7 but had network problems with it. With a help on the forum I was able to flash a new rom using the omap4boot, smartflash, and OS hacking utility. The kdz file had a v21e baseband. I was able to get back on gingerbread but the phone became P920. I reflashed the CM7 because I thought with the v21e baseband I could get the network working. I had the same problem again. I flashed the phone again but this time with a different baseband( LGP940_V20D). I still had this problem on it and I tried to flash the v21e baseband among others but the V20D baseband doesn't erase. Please I need your help. I am in Ghana
