I screwed up my phone

Hello everybody, I think I screwed up, but CyanogenMod installed immediately after restart and then nothing worked: he is always in flight mode, I can not connect wireless or bluetooth disappeared and even the IMEI, on the menu CyanogenMod i restore the settings already manufactures but still same.
Any solution? I do not mind putting it under warranty but I have to delete the icon of the superuser ...
Thank you.

Seems like You did something to the baseband/RIL
Or... do you have the p990 O2X or the p999 G2X?
the ROMS are NOT same for the 2 phones...

thanks for the fast response, but whow i know if are one or other?

You can't install P999 CM on the P990, it has an assert check to prevent it. Look for a stock ROM thread in the dev section, this will get you back to stock, although I don't know if it'll get your IMEI back.

You don't know which phone you bought? G2x is T-mobile branded, has T-mobile logo above screeen instead of LG's
Don't worry, it's easy to reflash everything, just need to download right tools and follow a guide

ok, so i have the p990 O2X, what i do now?

I was in troubly with my o2x this weekend but following this process this saved it.

(In the end it turned out I did not have to go back to stock ROM. I re-installed CM7 after wiping data/cache in recovery and that worked).
Im not sure if the smartflash tool will give your IMEI back...

i pick up therom for my country or other?

[Q] Phone Won't Detect SIM Card Anymore, No Signal

Hi Team!
So this is the story:
Got my unit
Flashed CM7
Got LG GetRil
Had 226(I think) RIL and xxx bb
Downloaded matching RIL (622 GB leak)
Worked fine
Changed Phone
Put Sim card back into my unit
Now it doesn't detect the SIM card, doesn't ask me for PIN, and just says no signal (duh)
Which means I can't flash the RIL back (if that is the issue)
What do I do?
Kind Regards
¨Neefy

Try a different BB/RIL, you probably have the unknown BB issue if you're using the 'gingerbread' 622.

Yeah that's the one! But how do I get a new one when I have no connection on the phone?
Steps would be appreciated

You do it all off the phone.
Have a read of this: http://android.modaco.com/topic/335494-12-aug-smartflash-stock-baseband-release-103521-20110725/

But don't I just have to change the RIL back without changing the BB? Without whiping my entire phone and such..

Er, I can't remember if that worked or not when I was in the same position, but you can try.
Temasek has a bunch of CWM flashable RIL's in his Mediafire folder: www.mediafire.com/temasek

[Q] Unable to make calls. How to solve?

Hi,
I have a strange problem. I am unable to make calls from my P990. If i try to make calls with UMTS active my phone does nothing. It is unable to call or get called from anybody. SMS do NOT work most of the time.
In GSM mode i can send and receive SMS messages and receive calls. But i can not make a call. It rings but when the called person answers the call my phone just ends it.
I think this problem can not be ROM based, because i switched from multiple CM10 nightlys to the leaked ICS by tonyp and harsh a few days ago and the problem is still there. While i changed the rom i did every wipe i could find, cache, davlic cache, internal sd and factory reset and fixed permissions as well.
Before switching to the leaked ICS rom i tried different (at least five) basebands to overcome the in call audio bug (loud strange noise on the called persons side) which worked for a few days, but then started to develop this problem. With the leaked ICS rom i tried both the P990_V28E_00_CP.fls and P990_V28G_00_CP.fls from tonyp's download site.
Can anyone think of a way to solve this really annoying problem?
If you need more informaion, like log files, build numbers, etc. please let me know what exactly and i will try to provide them to you.
Thank you for your help.

I tried this today, same problem here.
Something i forgot to mention is that when i try to call somebody and it does not connect i have to force quit the connection to the mobile network to end the call attempt from the phone. So i have to either switch in to airplane mode, deactivate the mobile network or switch from gsm to umts or the other way around.
If i do not do this the phone will try to place the call as long as possible with no result.
Do you think i should try and go to stock froyo and see if the problem persists?

u can try to nvflash the stock rom.it'll be clean then.
i-ve had the similar problem with leak ics rom.
my sim was over 10 years old and after changing the card problem was solved.
my telecom gaved me newer one with the same number.

I flashed the stock (2.3.4) rom (kdz version) with AIO-P990-ToolKit_v1.1-fixed which uses the official LG flash tool after making sure to have the gingerbread partition layout.
So now i have an old system V20Q_00.kdz with Baseband version 1035.21_20110725 but i am still unable to make any calls.
I will try to match baseband and ril next, but if this does not work i have no idea what else to try.
Anyone else?
Thanks.

OK, didn't work either.
Next try is the rom and the baseband from here http://forum.xda-developers.com/showthread.php?t=1504280.
ROM: Gueste2X "GoodBye" v2.0R
Baseband: v20l, 1035.21_20110725
Sms work without any problems, but the main problem remains. Calls, last about 3 seconds. Regardless wether the called person answers the call or not.
Calls to me are working perfect. Checked my APN settings and they are find to.
Is there any logfile i should provide to help track this problem down?
Any hints, suggestions ?
Thank you.

Well now it becomes really strange.
I tried a different sim card a few days ago. Same problem. Unable to call anybody. Today i tried it with yet another sim card. Calls worked perfect.
The only difference between the sim cards is the following. My original sim card is from bob (virtual provider from A1) and the first sim which did not work is from A1. So technically they are from the same provider. The one which worked is from a different provider (telering).
What adds to my confusion is the fact, that my sim card works perfectly in another P990 without any problem.
So somehow the combination of my P990 and sim cards from A1 and its virtual provider bob do not work. They send me a new sim card during the next week. If it works i'm happy and can finally make calls again.
If not i will change provider. :crying:

No Sim Detected LG Optimus 2x :(

Hi
My phone suddenly stopped detecting all sim cards ( I have tried various working sims ).
It is running CM 7.2 and has been running cm 7.2 for a few months with no problems.
Today I took out the sim and put it back in to reboot, all was fine. I went to shower, came back and the sim suddenly stopped being detected.
I have tried to google but it seems most problems are to do with flashing a new rom and having the sim not work, my case is that the rom has been the same for a few months.
I have tried to flash different roms and I still have the same problem. I have a gut feeling it is the hardware that reads the sim that is faulty.
I have read something about a baseband, I dont know what that is but if it helps, when i go to the settings and click on 'about phone'
It says there is a baseband and it is version something. There are no question marks or anything like that.
I appreciate the help and would love some more troubleshooting suggestions.
The worst case scenario is unrooting it, flashing stock rom and send it back to warranty. I actually don't know how to do that so if anyone has a guide lying around please link me on that.

I have similar problem with new boot loader.
Download getril app from play store and see if your baseband is OK. If not, download and flash matching baseband from development thread. You will loose all personal data and your apps after flashing. Then download new ril with getril and reboot. Good luck...
This method was no helpful for me. Maybe you will have better luck.

Thanks for the reply,
When I first opened getril, it said RIL not found, I did not have one. I downloaded one and then it said RIL does not match. I then redid it on another firmware and it now says RIL and Baseband matches. Is this enough? The only weird thing is the baseband has canada and europe in it. I am from Australia. How do i tell which baseband/ril I need?

First you flash BB, then download RIL with GetRil. Read completely through BB sticky topic in development section. All answers are there.

You can flash as much as you want, none of that will help. Had same issue once, flashed almost everything there was through SmartFlash, NVflash and all of that. This is what you need to do:
First, remove the battery from your phone. Write down the IMEI. Now boot up your phone, write *#06# and see if the IMEI that pops up is the same as the one you saw behind the battery. If not, let us know and I'll hand you the solution, but first check if the IMEI matches.

I checked the IMEI and it matches.
I have some extra information if it helps, when I choose a random RIL from getril, the battery might become a ? mark and the sim card not detected error doesnt show anymore, however when I put it back to the original RIL, my battery bar starts showing the 'power left' and also the sim not detecting error shows again.

I get the SIM Toolkit Incompatible Handset error and then whether I press OK or Cancel, shortly after I lose mobile network access. I've been trying all manner of different things, Smart Flashing, NVflashing, changing basebands, Rils, you name it.
I'm currently on the V30B root ROM http://forum.xda-developers.com/showthread.php?t=2064793 and the Ril matches the baseband from that ROM, but that hasn't helped either. So I went and check the in phone and behind battery IMEI and they are different! I'd love to hear what your solution to this is!

My problem was no service and IMEI unknown... Never managed to solve it. Reverted to old bootloader and problem solved.

IMEI Solution
If IMEI does NOT match, you will need to do this:
Check if you can get in a menu by typing 1809#*990#. If you can't, you will need to use a GB ROM (I remember I used Homero's GB NVFlash as I was on ICS bootloader and couldn't get access to it on ICS). Follow these steps if you are sure you can get into the menu:
1) Connect your phone by USB.
2) Enter 1809#*990# in dialer.
3) Select Port Setting -> Select CP USB
4) Install a program called Hyperterminal on your PC and open it. In COM settings select same port as in device manager -> LGE Mobile USB Seial Port (should be 115200)
5) Type at%imei and it should respond by saying OK
6) Now type at%imei and it should now display your current IMEI number.
7) Type at%imei=XXXXXXXXXXXXXXX where X is your original IMEI number.
8) Reset phone.
You might have to reboot your phone after step 3. But see if it works without.

I have been thinking that this is a hardware issue, I have not changed a single setting/rom/baseband at all, the sim just wasnt detecting when I came back to my phone. The rom and settings were the same for a number of months.
I am now going to give it in to warranty, however it only has 1 month left. I have tried to install the stock firmware but with no luck..
I found a rom to flash for my region, it is a zip file but when I try flash it with Clockworkmod, it says installation aborted....
Shouldnt I be able to flash the roms with CWM? The file is a zip file just like the CM7.2 rom I flashed. Do I need nvflash instead? I found the rom here :
http://forum.xda-developers.com/showthread.php?t=1852112 (the download links were removed so I googled the exact same rom)
I was also told that if I just use the LG update tool, it sohuld automatically update the phone to stock firmware AND unroot it, only that the update tool gives me an error. Whats the best approach guys?? I need to get this fixed before my warranty goes.

Your imei should not show in settings, it should show in the back of your battery and when you dial : *#06# into the phone (where you dial numbers for calls).
Cant help you with baseband.
OP here, I am trying to unroot my phone and put stock firmware to get warranty to fix the simcard reader ( i believe it is a hardware issue ).
If I use nvflash and flash any stock firmware I can find on the internet, will that be OK? I have a feeling each region of optimus 2x has slight differences in firmware, eg swedish stock roms and australian stock roms may differ in the default applications etc.
Will it be ok to just install any kind of stock rom for my warranty? Help would be appreciated my warranty is running out in less than a month now.
I also tried to flash stock firmware with CMW, it didnt work. I am about to try NVflash, so I went into greater detail in page 1 but no one replied yet. If you guys know please help. I am more familiar with CMW than NVflash. I have not used NVflash yet.

After I finish typing in 1809#*990# in dialer, nothing happens. If I press the green phone handset icon to dial that number it comes up with an error message of "Mobile network not available".
Any further advice? Thanks.

Okay, I failed at reading comprehension – it has to be an LG Gingerbread ROM for this code to work, NOT a CM-based one!
Trying one from somewhere-I-cannot-link-to-yet

Success! Once I was back on the original stock LG Gingerbread ROM, I could reset the IMEI and make/receive calls again using this method. Thank you very much!
Now all flashed back onto a nice "working" nightly CM10.1 and a very happy little device.
Many thanks all.

Hi,
Anyone have a working link to "progmaq-default-cm-10-20121105 ". My Optimus 2x has been bricked as well, and can't find any other version of this on Google unfortunately
Appreciate all help.

[Q] Full signal but not able to make calls HELP

Well i got a problem.
My LG optimus 2x doesn't want to make when it has full signal. And that's ONLY when it has full signal. As soon as I start calling it says call ended. Other people can't call me either. Everything else works fine from internet to messaging (receiving and sending). I have tried numerous basebands (0725 v20q, 0725 v10d, 0218 v10b) and the one I'm on now which is V30A.
I'm currently running stock LG 4.04.
I have tried the phone with a different sim and it still didn't make calls.
Switching to 2G or turning airplane mode on/off doesn't help neither doe turning on wcdma or gsm only signal.
I was installing the basebands with LG P990 All in one ToolKit.
ANY HELP GUYS.
Thanks

Switch to a custom rom ^^

Already tried it doesn't help. I will flash Avatar ROM again but first i want to fix this

Nobody knows? I don't think it hardware since the phone can make calls but only when its not on full signal.

Could it be IMEI problem?
Have you tried a different sim card?

Dial *#06# and see if your imei appears

IMEI problem what do you mean by that?
The IMEI does come up.
And yes i have tried different sim cards with the same result.

Does the displayed imei match with the one printed on the sticker under the battery?

Yep they match.

You have the problem which I had when I was using su660 basebands. As I see you were trying p990 basebands maybe you cold try a su660 baseband. Here's the su660 baseband with it's ril Flash the bb with smartflash, then if you are on stock or stock based rom copy the ril file to /system/lib and set the ril permisson to rw-r--r--

Will try. I'll post back if it works or not.

Of course, flash avatar rom or any other which grant you root acces or just root your stock rom, but if you still have that problem without changing ril it just will be a worthless effort.
If you still have that problem try this. Maybe it wil help. I know it is for fixing some kind of wifi-mobileinternet transation thing, but you can give it a try, you will lose nothing. Read carefully the post. I think there is nothing to worry about. I perfomed erase CAL numerous times without no problem. I would recommend putty instead of Hyper Terminal.

Just a quick question do you know what erase CAL does? can i use it while flashing a stock rom with baseband?

Erase CAL deletes the calibration data in the radio. By radio I mean that part of the phone which is responsible for catch signal/network. When you perform Erase CAL you lose your IMEI, but you can restore, that forum link I sent describe it how to restore your IMEI after erase CAL.
Answer to your second question: You can only use erase CAL when you flash baseband, and you need stock rom to restore your IMEI.
Why you need stock rom? You need stock rom because it has Hidden menu which is missing from custom roms. Hidden menu is essential to restore your IMEI.
You can find your IMEI on your phone's box or on the sticker under your battery, or type *#06# in the dialer and it will show your IMEI.

I suffered from this problem when I installed Kaspersky Anti-Virus. It automatically enabled its filter and I couldn't make or receive calls, depsite the signal strength or 2g/3g.I disabled the filter and it worked after that. Also, unrelated, but I also suffered from a problem where after a few calls/texts/switching data on/off, I would lose connectivity until the next reboot. I solved it by disabling automatic time and automatically setting the time using the clocksync application from the play store. Hope I helped, good luck.
