Optimus 2x No Network

Hi.
I recently purchased a used Optimus 2x with a cracked screen.
The first thing I did, was to start it up with my sim card, to see if the phone was operator locked.
When I turned the phone on, it started up just fine and I entered my pin number just fine, but after that I didn't get any network on the phone.
There were only greyed out bars on top of the screen, with a red " x " next to it and next to that, there was a picture of a sim card with a red " ! " mark on it and also on the "drag down menu" there was a message saying "No network".
I tried reseting the phone to factory settings but that didn't help.
I think the phone is originally from another country, because after I started the phone after reseting it, the language was changed to spanish.
If anyone could help me figure out what the problem with this phone is, I would really apreciate it.

No network is odd, try flashing a different baseband, then root it, install rom manager and start fresh with a new operating system.

Thanks for the reply.
Is there a tutorial on how to flash a different baseband? Is there a certain baseband version I should get, or can I just install any baseband version?

Thanks shpapy.
I managed to flash a new stock rom, but unfortunately the "No network" problem still persists.
However. When I looked at the back of the phone, I saw that the water indicator had turned red, so I assume that it has been water damaged.
Could this be causing the No network problem?
Or could the phone possibly be barred?

if you paid by credit card get a refund through them, or if ebay dispute the purchase and send PayPal images of the water sensor. Its screwed if it got wet.

Is there some way of fixing it?
I've got a rework station and could possibly replace the broken component if I knew which one to replace.
I've reballed a few xboxes before and normally I just work on gaming consoles.
But I bought this phone to give to my brother for christmas. The guy in the advertisement only said that the screen on the phone was cracked, but otherwise worked ok, so I figured it was an easy fix.
But now the f****r won't answer the phone anymore, so I guess he's long gone.
I paid in cash, so theres no chance for a refund.
I'll dissassemble the phone tomorrow and rinse the pcb with isopropyl, but this isn't really necessary as the component that is causing the issue is broken anyway right? But still, I guess it wouldn't hurt to give it a little rinse.

Just flash a new baseband+ ril i recommend starting with .218 bb+ ril and work up from there. Also use CM7 as a rom. I had the same problem your describing when i flashed the wrong baseband on mine. And if all else fails nvflash usually works in the end.
Sent from my Optimus 2X using XDA App

Well I think I bricked the phone.
I flashed the 0405 baseband and 0405 ril and after that, the phone didn't even ask for a pin number anymore and also the Imei number was deleted in the proccess
Guess I should have read more about how to flash the phone properly before I started flashing.
Ah well. S**t happends, lol.
By the way if there is a way to fix this phone, I would gladly pay someone to fix it for me.
Just send me a pm if it's fixable and we'll work something out.

You ticked 'erase cp' didn't you?
Luckily you can write your IMEI back though.

Heh, use nvflash, then flash new baseband. I use .725 myself after flashing baseband > root> install cwm> flash rom.
@rusty i did that wrong once

Hehe. To be honest, I'm not even sure I flashed the ril file the correct way.
I placed the RIL zip file on the internal sd card and booted the phone into bootloader "the thing that was installed after I rooted it with nvflash", and installed the ril file from there.
I chose install zip from internal sd and chose the ril file and after that, no more Imei, lol.

But, like I said earlier, I'll gladly pay someone if they could have this phone fixed for me.
I really wanted to give this phone to my brother and it'ss really a shame it won't work, because I've already ordered a new replacement screen and everything.
My brother's really into android phones and I know he's been drooling about this phone and the samsung galaxy s2, so I really wanted to suprise him with this phone.
If anyone believe that they could fix this phone and get it up and working, please send just send me a pm.

Nvflash = flashing rom from low lvl, last resort, so no basebands etc.
There is tons of documentation on this, read it. It will actually make it simple to do and understand its in the development section: nvflash, smartflash(bb), getril, roms.. etc
Sent from my Optimus 2X using XDA App

Yes! I managed to fix it.
I flashed a stock rom back to the phone, using Smartflash and that fixed it.
When I turned the phone on, the Imei was back and I could make and receive phone calls.
The Rom file I used to flash the phone with was: BIN_LGP990AT-00-V10b-NEU-XXX-APR-05-2011+0
Thanks to everyone that halped
However, now I've got a different problem. I disassembled the phone and while disassemling it, I managed to snap the "antenna/ coax" cable that runs between the main Pcb down to where the microphone is located.
I tried searchin on ebay for a replacement cable, but couldn't find anything. Maybe I didn't search for the correct part.
Does anyone have one of these cables that they'd be willing to sell, or does anyone know where I might buy one?

No sim card problem

Hi i did a search for the problem but none of the other threads with this title matched my problem.
I'm hoping someone can help i rooted and unlocked the bootloader on my x8 and put on ginger DX about 2 months ago and it's been working great.
just for info I didn't flash any custom kernel
So to my problem i tried to send a text message earlier tonight and i wouldn't send. my phone appeared to have no signal. I moved about in the house trying to get a signal no joy. So i rebooted my phone when it came back on it said there was no sim card!
Thinking something had gone wrong with the rom I tried a full wipe through xrecovery to no avail so i then did a repair with PCC.
However my phone still says No sim card
anyone know of any other steps i can take to fix my phone?
if it's beyond me fixing it I'm with O2 and have insurance will they be able to tell that i rooted and unlocked the bootloader and is that likely to invalidate my insurance??
Thanks in advance

I had the same problem. did you use this guide HERE?
If not do the whole guide following his instructions.
or
If you did go to the bottom of the first post and look at common issues. One of them is sim is not recognised. All you have to do is use the other unlock tool.
You will have it fixed in no time!
Please thank me if you appreciate my effort to try and fix this problem.

I wasn't trying to re unlock my bootloader i just wanted my sim to be recognised, but if i reunlock it is it likely to be recognised?
I didn't use this guide when i originally unlocked my bootloader i used x8toolbox

Have you tried inserting the sim to other fone and see if it works? or try using different sim and see if the fone recognize it.
Im guessing your sim card was damage.

Just tried that just before i turned the computer on and i was just thinking the same thing then i saw your reply
now just need to unroot the phone and lock the bootloader before i ring O2
Thanks for everyone's replies and i'll try to put my threads in the right forum next time

You did not unlock the bootloader properly. There was a bug. if sim is working before and not working afterward. Baddaman54 is right. you need to follow the guide and troubleshooters notes. Even though this has been solved I will make this post so that if someone comes here with the same problem they can see all solutions.

I didn't follow that guide at all, as posted earlier i used x8toolbox and i ran the s1 tool which seemed to indicate it was unlocked fine
But i did it about 2 months ago. The phone and sim's been ok all this time running GingerDX with stock kernel.
it appears the sim is damaged not sure how it happened though.

[Q] SIM stopped working in my LG Optimus 4X HD

I'm new to this.
A totally random event. I restarted my phone one evening last week and it show no sim. Using the LG support tool I had multiple failed attempts to update the software. Then as sudden a the sim registration had disappeared it came back to life. All fine until again the phone just stopped registering the sim.
Phone is secondhand. And I have tried numerous times removing, cleaning and replacing the SIM. Tried another active SIM on the same network with no luck.
I've never had a 'bricked' phone so don't know what to expect but I imagine the phone wouldn't even boot up!
I have now rooted the phone and installed CWM recovery, still no joy and have in desperation performed a hard reset. Nada!
Software is V10h. I read something about EFS folder to backup but all I could find is a text file. The IMEI is not registering on the phone. It could be a very simple answer but currently I'm stumped. I have requested a replacement SIM but have little hope this will resolve the issue.
I hope someone has an answer...

re-flash 10h or 20a kdz. look for various tutorials on the forum. (btw, your phone isnt registring on network cuz your imei isnt being read, probably due to failed upgrade process
(or some other bug). it should be fixable though)
also, replacement sim wont help. its your cell phone that's faulty, either hardware or software, not the SIM itself
also, i'm not sure how it goes if your IMEI is blacklisted by your cell phone company - is it possible the phone was stolen? perhaps the original owner reported it stolen to his carrier and they blocked the IMEI?

If the IMEI is blacklisted, the phone will still show it correctly in the settings and the carrier will just block based on this. This is why changing an IMEI is illegal in most countries and why discussions on how to change it aren't allowed on XDA as it can get the site in serious trouble.

check if ur gapps are fine. reinstall all gapps. maybe u deleted some app that u shouldnt. happened to me too 2 weeks ago and i had no sim so signal , i couldnt see my imei, etc. if that doesnt help , then reinstall ur rom or install a custom one. I mean maybe u must be sure to check if u deleted some system app that u shouldnt. Since u have double checked with other sim , if its not from an app , then the above thread is right, the owner could have reported the phone stolen

Okay, strange happenings with this phone. I've not hd the opportunity to re-flash as suggested but by the by I put my SIM back in and it worked fine. IMEI registered in the phone settings and all was as it should be. Until again first the signal disappeared and when I restarted the SIM did not register. Has anyone experienced this before?

There have been some problems with this, but normally due the the RIL on CyanogenMod-based ROMs. I would suggest that you find the time to either reflash v10h or upgrade to v20A/B/C (as appropriate for your region) and see if that fixes it for you.

you still havent mentioned anything about gapps. this means you checked and you are sure that they are fine ??

So I have tried flashing software V20A using the LG software updater and now all I get is the phone booting into 'S/W Upgrade please wait while upgrading'
I can get into any other screen, despite pressing all combination of buttons together.
I have attempted reflashing back to V10H and try and get it back to how I had the phone. No luck there
And also tried again with V20A. No joy.
Is there anything else I could try?

I have always found this thread [TUTORIAL]Update firmware through flashing the kdz files( With Picture )Step by Step works perfectly every time.

Got the same problem here, running cm for a month with no probs, restarted phone and sim not recognized. Installed a backup of the original rom and everything ok. Reflashed kdz's and did a fresh install of cm and still no sim. Am now on Zaiben which is ok but takes about 15 mins to recognize sim?

Can't flash stock ROM, phone show only S/W Upgrade

A month ago I've upgraded to V20B using KDZ with this excellent tutorial: http://forum.xda-developers.com/showthread.php?t=2069723, and everything worked fine till yesterday, when suddenly all mobile connectivity lost, as if there was no sim card installed.
I tried various solutions from the web before flashing my phone to CM-10.1.3-p880, which was great for me, but alas, still no mobile networks and data. I then tried to flash back to Stock ROM, again using KDZ update, and I don't know what went wrong, the outcome was that now the device shows only "S/W Upgrade" screen and no more. I tried to flash several times using also Lg Flash tool, but every time it fails after 10% of the download process. I also tried everything on a different computer.
Plz help..
Thanx

You can try recover your phone with LGMobile support tool, without kdz flashing. In LG program in options you have entry update recovery, click it and follow instruction. I hope it helps.

It didn't fix it either.
Failed at 10% of the upgrading proccess.

i've seen like 3-4 people in the past month on the forum have this same problem (its like imei gets wiped), and all have issues reflashing. quite strange indeed. i don't have any tips for you other than to try reflashing via kdz flasher/another tool again and hope for the best

Try on another computer, this might helps. Do it on PC not on laptop on rear usb port.

Happened to me something similar today, but with the difference that I still have my IMEI and that I still can surf the web using 3G. Also my baseband version shows LGP880AT-00-V20a-234-XXX-MAR-26-2013 and right now I'm on latest CM11.
My problem is that I can't make calls, when I try to do so, I get "Mobile network not available". Also people can't call me and I can't send or receive SMS (haven't tried MMS btw).
I've also gone under "Settings -> Mobile networks -> Network Operators" and when I choose my network operator or select "Choose Automatically" I get "Can't connect to this network right now. Try again later".
Strange enough, in the quicksettings tiles I can see my network operator's name and the bars are full.
I was on Vanir 4.4.2 when this first happened. I have flashed already a few ROMs (like cm10.1.3, Zaiben, CM11) trying to solve this problem and all of this happens in all of them (clean flashed every single one of them). Also tried to restore with CWM some nandroid backups that were working previously and all of them are giving me this same error.
In "About phone -> Status"
I do have a signal strenght, which makes me think the antennas and the sim card are working correctly
Mobile network type: UMTS (I'm in Portugal)
Service state
Voice: Out of service (I believe the problem is somewhere hidden here)
Data: In service
Mobile network state: disconnected (this seems weird to me too, regarding the fact that I have data connection)
And like I said before, my IMEI and all the rest are correct.
I haven't tried flashing a KDZ due to all these reports of "soft bricking" their devices.... Don't know what to do... Any ideas?
Don't know If I shall provide a logcat or a dmesg... If so, when shall I take it?
Thanks in advance and sorry for crashing this thread...

what you described seems like ril crash issue, and ril doesn't connect you to network properly after that. the link in my sig may help you
edit:
just re-read your post, you are 100% sure it also happened on stock-based rom (zaiben)? if so, it may be that something different is wrong. try toggling airplane mode on and off when your issue happens and tell me what happens then

Hi and thanks for reply
When I push *#6# I get an imei number, so I guess thats correct.
However, I think I found the problem, it seems that it's missing one of the pins who should connect to the sim. My sim slot has only 5 pins like this:
Top
''
'''
Bottom
But ive seen on pics, there should be
Top
'''
'''
Bottom
I ordered a replacement part of ebay, so I hope this fix it.
Anyone who knows how many pins the sim slot should have?
