Phone crashed tried to fix it, now no signal

Hi guys!
I'm a little new to all this Android stuff and tried to learn how to fix my phone but I've been reading around in circles now for two days and still can't make heads or tails out of it.
I've got a LG P920 Optimus 3D that has stopped working.
Now what happened is it froze like a it had before and didn't want to shut down when I held the power button so I took out the battery. When I turned it back on it got stuck at the LG logo right after the LG sound played.
I tried some sort of LG update but that didn't work then I tried a couple of things I found on different forums something to do with the LGflasing tool or something witch also didn't work (or at least I don't know what I'm doing) and at the end I was able to hold some vol+3d+power and got a recovery menu and wiped everything I could find.
Now the phone turns on fine and everything works except for the phone part. I don't get asked for a PIN and it just says "no network" with any SIM card.
Here's the data from my phone:
Country of purchise: Slovenia
Android v: 2.2.2
baseband v: L6260_modem_sic_01.1042.00
Kernel: 2.6.25.7
SW v: LGP920-V10K-SEP-17-2011
Can someone pleas help me and explain what I'd have to do to get this thing working again because currently I'm out of ideas and I have no idea where to start.
Can I do something on the phone to make it work or do I need to flash something and if so what and how. I'm really lost here and can't seem to make heads or tails out of all this.
Thank you for your help, patience and I apologize in advance for my lack of knowledge in this area.

I punched in *#06# and it just outputs IMEI and blank. I'm guessing there should be a number outputted. What would this mean?

You wont connect to network till you get IMEI back. This is baseband problem. Check your PM i will send you instructions what to flash and how to restore IMEI.

Yes success!
I was able to use the method in the link above to put a newer rom on the device and it seems to be working fine.
Thank you very much guys. This is all very new to me. I hope it doesn't crash again since I was scared that I lost all of my contacts but thankfully I had a backup.
Best regards

having the same issues
Please help. can you send me the instructions also iodak to this issue.

Here you go. Works 100%. And you will get the new gingerbread baseband.

You cant write IMEI with hyper terminal until your IMEI is that strange number. If you cant get it that way with smartflash tool (erase CP). Flash lg prada baseband that will do same thing. After that flash 21e baseband and restore imei with hyperterminal.
Edit: check if you got drivers instaled.

Rare Baseband

i got this phone (is a tracphone lgl95g) y have flashed weapong2x i want to update my baseband in order for fix gps lock problems (im nicaraguan and my retired mytouch 4g dont have any problems with gps lock ) my baseband says NOV 07 , the lg tool says that my phone is already updated an say version V10F the allinoneg2x tool say the same :S i need help for fix gps or update baseband, i try tutorial but i couldnt done (sorry for my bad english lol)
Geetings e_e/

Maybe you have to do the offline update for it? There is a guide in forums.

Thanx
im trying right now thx for reply

Sorry fir the delay
I followed some tutorials but without success, I think my phone is some other type p999, all in one tool G2X tells me the v10c version is not supported, and I think the baseband chip is not the same as having tmobile, I hope you can help me I know it's ICS is close but I would update my baseband
PD: virtual windows xp with virtualbox

I remember reading somewhere that the tracphone G2x is NOT the same thing as the T-Mobile one, and isn't compatible (I think jboxer said something about it).
What is the model number under the back cover? That's probably the accurate model
Sent from my LG-P999 using xda premium

in the back cover i have this:
<GPLGL95GB>
FCC ID BEJP999DW
TRACFONE WIRELESS, INC
IMEI : XXXXXXXXX
S/N: XXXXXXXXXX
LGL95G
MADE IN KOREA
I want to upgrade my baseband because in any ASOP rom, "message sent" always shows me even when I have balance in my carrier or sent to random inexisting number, to give an example if I send an SMS to "123456789" I get "message sent" , being that it is impossible to send a sms to that number, if I can not upgrade my baseband, i would like to know if there is any way to fix this please
I think it may be a mistake to see if the message was sent, and that's why I always shows "message sent"

You might find info in here: http://forum.xda-developers.com/showthread.php?t=1305077
The phone you have is an unreleased prototype that was supposed to end up on tracfone's network but later cancelled. It's basically the same thing as the g2x but has minor differences that could cause you trouble.

thx i will read the thread, look interesting lol

I remember something I read about the Tracphone P999 being unable to be unlocked and other restrictions it has because it was going to be marketed real cheap but only able to work with that service provider.

I dont now about that , jboxer say on his thread that, but i have a unlocked tracfone p999 unlocked by box service e_e
Any idea about the sms problem in aosp?
if this could help Somethimes during i am sending sms (always in aosp) my phone drop the signal

How did they unlock your phone? Was it with a hardware box such as an Octopus Box?
The cell radio modem is the same as in the G2X/P999, a Qualcomm, not the same as in the O2X/P990.

Yes i guess that was hardware unlock with a box (i dont know what box) mmmm ok if the baseband chip js the same g2x chip why i have this error on the lg tool ? :/

The LG tool checks the phone's IMEI and ROM version before it will authorize updating. If the IMEI isn't in the database for a particular update, LG's update server won't authorize updating. Did you try the offline update method?

Yes the method that i used is offline with the script http mini server in the screenshot you could see it e_e

When the package is downloaded from the internet Windows 7 blocks applications from running. Did you unblock the dll and .exe files (Properties -> General) and set each .exe to run as administrator first (Properties -> Compatibility)? Did you turn Windows Enabler On before running anything else? Next, run the http server then the update.

I used offline method in windows xp virtual machine , i will try tonight with windows 7, i turn on window enabler before to begin the procedure e_e

I've used Virtual Windows XP successfully. The problem with it is that the USB port disconnects and has to be manually reconnected to continue updating. The problem with Windows 7 is that there's an inherent flaw in the LG updater which caused problems which I think have been fixed with the last updater. Try what I've told you in Windows 7, I've successfully done it but, if that doesn't work, try Windows XP mode.

I will try in a real xp machine e_e

A few months back my s2 fell in water and apparently I didn't let it dry enough before powering it own. When I did it came in and everything worked except reading the sim. And of course it had no imei number and no baseband. I had a friend check the hardware out after I tried to flash it back to stock and tried flashing the imei back with one of those boxes like the z3x I think that's its name. But it turned out there is a chip on the board that holds this information that got fried. But everything else worked fine. But I could forget using a sum on it again. So my guess was maybe that same chip on ur board might be the issue if u tried flashing back to stock and it didn't work. Or u could have that random efs corruption problem. But seeing as flashing a stock rom won't kill no one I would suggest u go back to stock and see what happens. And btw did u check and ssee if u sill have an imei number? And yeah u check by dialing *#06#

And about the imei number there are a lot of things associated with imei. For one its like ur devices ID there are some apps that are linked to imei like viber and things like that if I'm not mistaken. Without imei its like ur device has no identity. Its sorta how ur carrier recognizes ur device. So if u have no imei u have no phone. Or any telephony u have a tab with working wifi, Bluetooth and u can do almost anything but no mobile data and no calls. But lets hope that's not ur issue. Good luck man.

[Q] hellfire sandwich rom

Hello,I searched all forums but cant find a answer to my issues,hopefully someone can help.
I flashed hellfire sandwich rom to my g2x Now my issues are
picture messaging dont work-I can send regular texts but not with pics nor can I receive them
I get process at android ,com has stopped and I click ok bit it keeps coming back until I reboot
the second one is my battery bar indicates a full charge but its been on for about 6 hours now-I did install battery recalibrate but it still does it
third is that my phone number says unknown and my voicemail number is also not known I have a feeling this is related to my mms erros too.
Thats about all please help.I did have cyanogenmod 7.1 installed before and was having the messaging issue then too.I did switch to another version of hellfire after that and everything was working great except my battery indicator had ? mark in it and the phone shut down and had a hard time rebooting.I used g2x scrubber before I installed the hellsandwich rom and followed directions to the t so I dunno whats wrong
Thanksfor any help,Steve

When you go into settings/about phone what baseband shows up?

m6600a-scautnz-2.0.972ot 1 [may 21 2012 16:00:00} TRULGE_08.09.02R_MDM

Were you originally on 2.3.4? I don't know if it will help or not but if so try flashing the new baseband fix zip file. Its a sticky I believe in the g2x general section. I know its meant to fix problems with calls but it couldn't hurt I guess.
Sent from my LG-P999 using xda app-developers app

yes I was on 2.3.4 I will give it a shot and let you know how it works out.
Thanks,Steve

No problem. I double checked, its stickied in the general section under “how to fix popping in calls" just download it to SD card and flash in cwm and reboot. Hope it helps!
Sent from my LG-P999 using xda app-developers app

well it was worth a try but no go,any other suggestions?

I honestly have no idea. I'm currently running an ICS rom (eaglesblood) and have none of those issues. However my voice mail had the same "no voice mail number" error. I'm assuming you're on t-mobile...if so, just put this number in for your voice mail and it will work properly:
+18056377243 This will definitely fix your voice mail...as for your SMS messages...hopefully justjackyl comes in here and can give you some better information

I think you should try reflashing your rom. Or try a different one. You have a lot of weird issues. When you go from gb to ics or vice versa are you wiping /system?

Good call twitch. Make sure you wipe /system under mounts and storage in CWM!

i attached 2 pics

I switched roms to hellfire 2.4.2 everything works except I have a question mark in battery indicator,no chang if plugged into charger either
phone randomly shuts down on me getril still says ril/baseband dont match i tried switching ril's from the drop down list but nothing changes.
under baseband in getril it say recommended march baseband. Any suggestions?

Whats the model number on the label?
We are not quite sure how you have a may baseband, the P999 basebands carry June and March months. I believe June 15 2011 and the last was March 11 2012.
I keep wondering if your not using the Wind G2x model which is an O2x P990 branded as G2x or even using a P990 in general, which this than would be incorrect ROM and could definitely cause all these issues.
In you screenshot it will say P999 because the ROM build states that, not the phone.
Check your model number sticker please.

I have odin back to ics 4.0.4 and then tried the dialer code to no luck, then tried a stock 4.1.2 and no luck. I did get my meid back doing this and my phone number is still correct. I do have qpst as i have flashed a few phones to cricket. Would just hate to screw up my replacement s3. I dont have original box as it was an insurance replacement so i believe its a refurb.ill look for a qpst instruction page but if anyone knows the link i would greatly appreciate it. I was able to get my text and talk back but still stuck in data roaming..... so i guess qpst is next step. Btw i did flash back to PA 3 4.2.2. Should i odin back to stock b4 using qpst??

fixed
Got it working after two days of messing with it. Used the samsung xda restore app, it was hard to find the .rar but i was able to simply type in g imei. Strange part is someone had mistakenly typed my imeid into verizon stating that it was lost or stolen so once i called verizon with the proper imei provisioned i was good to go. Thank u all for ur help!XDA is the best site for accurate feedback from people who care.

Woooo xda!
