Yes friends, I'm really in trouble my OB. Two days ago, I flashed a patched ROM to get my phone rooted through the smartflash method. Everything went OK, but short time after, I realized that my 3G/GSM signal was completly unstable.
The phone gets the signal but only for a while. Then, it loose it. Can't call, can't receive, no 3G. Full disaster!!!
So, since two days ago I'm eating every LG forum trying to find the solution, but it's impossible, no way, I'm about to throw my phone through the window.
So, pleeeaaase, could anyone help me???
From my forum lectures I could imagine that is anything involving baseband, or perhaps some network config in the service menu "3845#*970#".
My spanish network works in GSM900/1800 and WCDMA2100
I've tried to flash several STOCK firmwares with the same result: no luck.
Please, any help will be apreciated.
Thanks

First of all Question belong to Q&A section...
try a stock based custom rom like zeus, marvel or supressed or a non-stock AOSP like CM7... maybe is a hardware malfunction...
First of all, sorry about the wrong section I posted this thread, and thanks for the reply.
I don't think it's a hardware issue, because the phone was Ok before updating to a new firmware.
Anyway, after work I'll try to flash a custom ROM if no one gives me a better idea.
I'll post the result, but please, I still accept suggestions in order to solve this problem using a stock firmware.
I also have mesuared gps strenght signal with an android app, and it detects around 25%-30% where another phone with same carrier detects 75%.
Thanks, and keep in need of new ideas.
Sorry for any written mistake. My english is not as good as I wish. :·(
If you tried several roms like Zeus, and noone have solute your issue, than you should assume, that you have a hardware problem. Of course you should compare the signal strength with an other Smartphone, due their format cause a bad signal reception.
Go back to stock. I recomend this: http://forum.xda-developers.com/showpost.php?p=18946763&postcount=1
and here pick your corresponding stock:
http://lg-phone-firmware.com/index.php?id_mod=1
other thing: In which country are you using the phone, and it is buyed there? Maybe bad bandwithspecs.
Regards!
Thanks Pacos1, the phone is being used in Spain, and also it's been bought there. (weird to write you in English :·)).
I still haven't tried a custom ROM like zeus or another one. I wanted to solve the issue with any Stock ROM, but as I have been trying several with no luck, I think it's time to try a custom one. I'm thinking about Zeus.
But first, as you've mentioned bad bandwith specs, I remember that the problem came after installing a patched stock ROM from russia. Once installed, I found out that spanish language wasn't included, so I returned to a patched stock spanish ROM. At that moment I started to have signal unstability.
So, I ask you with hope, do you know something I can do to restore spanish bandwith specs, and how to do it??
That would save my ass, as I'm really touched with this trouble.
Thanks again and hope a good end to this embarassing stuff.
I'm going to give up and call the SAT center. I've tried a lot of things for the last days without luck and no more ideas come to my brain.
I've tried Zeus ROM, it's quite good and nice, good performance, but still unstable signal. I've return to an offical ROM through LG update service and again unstability.
My conclussion is that is something about RIL and baseband, but don't have enough knowledge to solve it, then it's time to ask for official help and prepare my wallet (phone is out of warranty :·( )
End of the story.
Thanks

Hello!
I have big problems.
The fact is that recently I have started a problem with the wifi: icon appears and disappears constantly, the phone tries to reconnect and lose the connection. signal is excellent. I thought that things in the firmware (Super D 1.11), but I haven't time to deal with it.
Now I have started the same with 3g/edge. Icon disappears every 3 seconds, then it appears again and disappears. Internet use is not possible, the phone due to constant reconnections began be slow and very fast mount battery.
At first I reflash same firmware. It did not help. Then flash a few more firmwares - no. Then I thought that problem in OTA, and tried to flash to ota-radio-2_22_19_26I, but to luck, because I have it before.
Now I don't know what to do, use the phone is impossible, I suspect that he just broke down. Can't use guarantee, living in Ukraine.
Help please.
P.S. Sory for my english.
someone ??
have you tried a wipe and a flash of the newest radio? The newest radio version is 2.22.23.02 and can be found in the first few pages of the development section. It might be a hardware issue if those two don't fix it.
Just flashed it. Didn't help
Hi folks,
I can't post in the dev section so I'm hoping someone can answer here instead. Searched imilka's thread but couldn't find anything that helped me. Wipe & reflash has worked for others but not me.
Wifi doesn't work for me. It worked when I activated it in the setup wizard after flashing the rom but after the first reboot it doesn't present me with any networks and it doesn't connect to the one I configured. I know the wifi device works because the mac address is identified in the status menu.
Also, battery time isn't very good. Less than half remains after being fully charged then left alone over night.
I have tried a full wipe & re-flash and also flashed the last version released yesterday. Does anyone have any tips or do I just wait for a new version? Seems weird that it works for everyone else.

Indeed, I didn't come accross any of these problems... I don't know what to say mate, might have something to do from whatever ROM you came from, some kernel remnants...but again, that's just guessing...
What I'd do in a situation like this would be to revert to a stock GB, use jBroid's kernel cleaner, and then try to reflash Chainfire's repack and back to CM. That's just what I'd do...
I'd try to do a factory reset first. That way you'll get another chance to setup your WiFi from scratch and see what transpires. If it fails, it's back to basics, most probably. Rooted GB --> ICS Repack --> CM9.
It's such a hassle to reinstall everything again.
I'm downloading a stock rom now and I'm going to try flashing the modem partition. Perhaps the modem in the chainfire repack I flashed before is not 100% compatible with my phone... Otherwise I'll just have to stick to mobile data.
Flashing modem made no difference so it's something with the ROM. Luckily I have a good data plan so I'll just leave it and see what happens in the versions to come. If anyone has an idea, feel free to let me know.
And thanks for your answers guys.
Suddenly it all works. Thank you Google. You're swell!
Hi guys,
I already have some experience in changing ROM, and so on.
Recently, I gave up the experimental ROMs that have always worked well for back to cyanogem stable 7.2.
The first week was very good, but in one afternoon, for no apparent reason, my signal disappeared. The smartphone settings showed me that my number was +0000000000, the imei was shown correctly, but for some reason imei_sv was unknown. Put other roms, but the problem persisted. So I decided to go back to the stock ROM, I lost my root and CWM. Surprisingly, at first, I could make a call and receive another. But after the excitement, the same problem again.
Sometimes, the settings show my number correctly, others turn to show +000000000 ...
Nevertheless, the display shows me a good sign, and the phone recognizes messages in my mailbox.
* Detail: I can not in any way put CWM. I spent the whole day trying, and absolutely all the methods that the internet gives me do not work.
UPDATE: Finally now I have CWM, but the problems are present.
Rom: European stock v30a - Android 4.0.4
Baseband version: 1035.21_20121130
If someone can help me, would be very grateful!

I did not do this procedure. But I turned it into a brick, and formated all partitions and redid them with a fantastic tool here forum, All-In-One Toolkit -> http://forum.xda-developers.com/showthread.php? t = 2020737. This procedure can, by itself, restore a corrupted imei or delete data cal?
If not, how could I do this? And because it is corrupt without any procedure? I was at home and no apparent reason the phone lost signal. At 13:00 he had signal, and at 14:00 had no more.
I considered another possibility: virus in sim card.
This test will only be able to do tomorrow, using a sim card that is not "infected", if that would be the problem.
UPDATE: Today I bought a new sim card and tested it with the stock rom newly formatted. I had the same problem, but strangely, the first few minutes of use, everything works. After a few minutes of use, the signal sim no longer works, and after a few hours, the smartphone connects on a rece wifi, but the signal does not stabilize: connects but does not have internet access.
REALLY DO NOT IDEA HOW TO SOLVE THIS!
I really need help!

You really should try Erase CAL data. http://forum.xda-developers.com/showthread.php?t=2087215&highlight=wifi the first Post what you need. If you having problems with restoring your imei then use putty instead of hyperterminal
I did not do this procedure, but deleted all the partitions and redid them, and I believe it made the signal back. Thank you all for the help!
UPDATE: The problem is present again! I restored Imei, erased CAL data, change billions of basebands and no sucess. If I search for networks, it´s fix, but only any minuts, and the problem returns again. I have sucess for any days, but the sms were frequently lost, and after, my signal losts completly. It´s a possible hardware problem?
I really need professional help of my friends of XDA.
You are tried to erase cal data again by smartflash using 30B Rom and Baseband 30B?you o2x is from china or korea?

I have been using CM11 (14-03-2014 I believe), without major problems until yesterday. Sometimes my phone seemed to disconnect from my SIM and I had to re-enter my pin code to reconnect to my operators network. But as of yesterday my device doesn't seem to recognize the SIM card, It doesn't ask for a code at all and can't make any connection whatsoever. I didn't change a thing, this problem started out of the blue.
I wiped cache and dalvik, updated to the latest CM nightly (08-05) but that didn't make any difference. In other threads I read about the baseband that might need an update, but I can't check which version I have now because when I try to enter the hidden menu I get the no network connection error. The strange thing is that CM11 has worked with (I guess) the stock baseband.
Is my phone tripping or could it be that my SIM card is broken?
Help and thoughts will be very much appreciated
Try it on stock to be sure about it.
After some searching I found a phone that could fit a regular SIM card, a Blackberry 9900. My SIM worked perfect in this phone, so that is not the problem.
I Also did a complete wipe and installed a stable version of CM 10.1.3, but that didn't seem to help. I hoped that a downgrade would have done the trick. I might try a ICS ROM or the stock firmware, but I kind of lost hope and i'm starting to think this problem is hardware related in stead of software. I'll report back with results on stock firmware and the ICS ROM.
How can I make sure the SIM reader in my phone is working properly?
Sorry for double posting, but I got an update:
SIM wasn't working with ICS so I decided to go back to the stock ROM. However, when I tried to flash V20B.kdz with KDZ_FW_UPD, the program got stuck at wParam=2010 and iParam=210. The phone is now stuck in S/W Update mode, and I haven't found a way to restore it yet. I will argue a little more with my phone when I get back from work, I'll open a new thread on how to unbrick when I can't do it myself.

I have the same problem, and exactly the same error at reflash.
Dead end. Buy a new phone .
I tried to flash it about 80 times. One guy from a gsm repair has a bit luck and make it work at the first, but then, when he wanted to repair my imei, the phone stucked again in S/W Upgrade.
Yesterday, my phone just decided it didn't want to be connected to a network anymore. I was running DynamicKat ROM. It just happened out of nowhere and continues today. I've tried flashing different ROMS and they install fine, but I still can't register to a network. I believe I need to update the modem, but I'm not sure. I'm currently on baseband version ANK4, but I think I need to update to BOC4. Does this sound correct? Any advice would be great, and if you might point me in the direction of any files needed it would be greatly appreciated as well. No need to link, but just a general section where I could find the files would be helpful as I seem to have little luck with the search function here. Thank you in advance.
EDIT: Ehhh... Nevermind. It just started working again. I can't explain it. Suddenly I was connected again.
Always a good idea to check your APN settings if you are in a known coverage area with a new ROM. Been my problem 90 percent of the time

Funny you mention this as I run the same ROM and have had this occur to me whilst traveling around my area and in and out of T-Mobile "Dead Spots" which seem to be many...
Even called T-Mobile to report and best they could tell me is go into "More Networks-Mobile Networks-Network operators" and select - Select automatically.
A real PITA when you driving down the road and need to call out or re-connect your call with someone.
Note: I've had numerous issues on different ROMS similar to this so I pretty much blame T-Mobile and their service in my area unless someone else can chime in, I would be curious...

I had a similar problem on DK, except that it was unmounting my sim card completely & I had to reboot to get it working again. Happened every hour or so, very frustrating. I tried a different rom & the issue went away, so it's definitely something funky with DK which makes me sad cause that's my favorite rom.
I just reflashed it last night though & I took the precaution of completely reflashing ANK4 through Odin and redoing root & TWRP too, then flashing DK like normal. So far, so good(and it seems to have fixed the battery life issues I was having as well, yay), so you might try that method & see if it helps for you too. But be sure to back up your internal storage first cause odin WILL wipe it. Learned this the hard way, bye-bye all my pictures & titanium backups :/
Files I used can be found here.. BOC4 is for LP, so you should be fine with ANK4.
