[Q] No network connection and IMEI unknown - LG Thrill 4G

My phone specs are:
Model Number: LG-P925
Android Version: 2.3.5
Kernel Version: 2.6.35.7+
Build Number: GRJ90
Software Version: LGP925-V20p-FEB-22-2012
So it used this nice guide to root my phone: http://forum.xda-developers.com/showthread.php?t=1975933
I then had to use this guide to install ClockworksMod because it seams that nothing comes easy on this phone: http://forum.xda-developers.com/showthread.php?t=1257588
I loaded the stable version of cyanogen for the LG Thrill and it starts up and runs, but the problem is that I get no network connection, when i try to import contacts I get "No vCard file found", and my phone says that my IMEI is unknown.
I have looked around and seen that it may be because i have a bad file in EFS, but i have no idea where to find this so called EFS folder.
Any help on this matter will be greatly appreciated, and try to keep the explanations at a low level because I only started doing all this stuff yesterday so i have a limited understanding on what is actually going on.
And I have tried to do the following steps:
1. Connect phone by USB
2. Activate USB debug mode
3. Enter 3845#*920# in dialer if that doesn’t work try 3845#*925#
4. Select Port Settings -> Select CP Image Download
5. A new device should appear at let it install
6. Open Tutty and select serial protocol. Click on open
7. Type AT if response is not OK, change port number (it is possible that when typing you don’t see any letters)
But i cant get past step 3, because entering either of those two doesnt do anything on the phone. I'm assuming because those are specific for Gingerbread, but when i re-install gingerbread and try these again Tutty doesnt open when i select serial protocol, it just gives me an error.

Ha, i found my problem. I dont have a baseband, it comes up as unknown. Did a little reading and found that "he baseband is the subsystem of the phone that controls radio communications. It's a chipset on the phone that directly controls cellular hardware and communications with cell towers."
Well now i just need to figure out how to get it on the phone and which one to use.
Edit:
Ya I'm still having problems i can't get any of the ROM's to work. I was stupid and didn't save Nandroid backup so i cant even go back to what i had before. I tried going back to the standard P925 ROM but it still didnt recognize the SIM. When i try the P920 ROM the SIM is recognized, but all the text is shifted so i cant read most of anything.
Any help would be much appreciated

Get thrill seeker 3.0 or higher I'm on 3.0 not the greatest rom but works

[Q] 2.3.6 Disables Cellular Connection -- No Signal

Device: Nexus One
Android Version: 2.3.6
Baseband Version (according to settings): 32.41.00.32U_5.08.00.04
Kernel Version: 2.6.35.7-59465-g4bad32
Build Number: GRK39F
Carrier: AT&T (This is an unlocked Nexus One)
So after the most recent update sent out by Google, my phone has been functionally bricked. I have lost all cellular signal and cannot dial anyone, even 911. However, Wifi and Bluetooth functionality remain.
The cell phone for some reason also does not recognize when it is connected via USB, and thus I have had major difficulties attempting to root the phone. Thus far I haven't found any means to root the phone.
Is there any way to fix this mofo? Or should I just get a new phone?
Edit: Also, wrong forum. Apologies. Move to whatever forum is appropriate.

What have you trued so far? Did you try taking out the Sim card and putting it back in? have you tried a hard reset? Also dial *#*#info#*#* and them phone info to see if you are on the right radio.

Thanks for the response.
I've tried doing a factory reset (about 3 times now). I've taken out the sim card, put it back in multiple times. I've done multiple power resets, as well as tried loading through the bootloader.
I put the *#*#info#*#* in and the phone info is set right (I believe) to WCDMA preferred.
Also tried to use passimg.zip (2.3.3) on the bootloader, but it didn't detect an image for some reason. At least that's what I read for the half second the bootloader showed something.

[solved by myself!] Network unavailable to one particular provider

This is some unique problem i have got.
Whenever i put in any sim from Network A (tata docomo, india) i dont get signal.....it says network unavailable.
But if i put the same sims in another phone i get signal (so obviously not network fault).
I get signal if i insert sim of any other network other than network A.
This happened when i was changing roms (was on v28g then went to stock froyo and then to stock GB without prob). I tried reflashing roms, changing BB/RIL NVflash, smart flash...but no help...I dont know what the problem is...please help me, This problem is only for one particular network provider.... Currently on CM10 fixed by marsgod, with wifi fix by beenee, with default RIL with su660 30c BB.
EDITED: My IMEI or SIM are not blocked by network....saw it with my own eyes at customer centre...
Please help....
it seems my imei number somehow got changed....i solved it by restoring my original imei number by this method...too bad i cant thank myself!! :laugh:
MODS PLEASE TRASH THIS IF REQUIRED
Here is for custum ROMS
Changing IMEI on engineering sample
1. install Better Cut 3.3.apk
2. Connect phone by USB
3. Select Port Settings -> Select CP USB from Better Cut Widgets
4. Start hyperterminal, in COM settings select same port like in devide manager -> LGE mobile USB Serial Port, 115200
5. Type AT if response is not OK, change port number
6. Type at%imei, it should display your current IMEI
7. Type at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x , where x,x,x... is your orginal IMEI number
8. Reset

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.

Bother. The 1890 etc didn't work on the p990 in android 4.0.4 (nor on my Nexus 4 incidentally), so I guess I'll have to flash down to GB. I'll let you know if I can get it to work, thanks!

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.
hahah after 2 sleeples nights i menage to restore my sim to be recognize ,whit this metod,.. NFlash rulles ))

this is also the best metod for unbricking your phone, .
INSTALLATION:
ATTENTION
The flasher with NVFlash clears all memory, including the Internal SD., so make a backup if u can..
Download this file: http://bayfiles.com/file/yKZL/eGZ31A/driver.rar The pack includes the APX driver (folder driver)
http://www.putlocker.com/file/4CEDEB7E0893B6F1
1.- Remove the battery to the phone.
2.- Press and hold Vol- and Vol+ and without releasing the 2 keys connect the USB cable to the PC
3.- Go to the progmaq-default-cm-10-20121105 folder and run flash icon... folow instruction., wait wait wait Enjoy!

I managed to get an old CM7 install back on the p990,but the above is still not working for me :/
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.

unlock, root, efs backup, install custom firmware from on a branded GT-I9000

Hello Folks,
the last days I have read so much, but all tutorials I read are pretty old or lead me in a dead end road.
Could somebody give me some infos what to do and how I get to a good result for my dad's Samsung GT-I9000
Unfortunately I have no windows computer here, which gives my headache with tutorials based on a windows connect. what I have:
- Mac OSX 10.10.4
- Heimdall 1.4, Kies, SmartSwitch installed
- Samsung Galaxy S i9000 (branded from 3 Austria - Hutchinson)
this phone was unlocked from a shop before, but my dad got no "unlock number". it has worked unlocked for some years. I wanted to try out if I can get into recovery by pressing "Vol.Up - ON" (no home button) and it just restarted. since then I get the popup for using "unlock PIN". even a working 3 SIM card from a friend does not work anymore. Android Eclair just shows a SIM symbol in the upper right corner with a red exclamation mark.
If possible, I want to update to a pretty new Android. I have read the post here that Coderom with Android 5.1. even runs on this model fine.
If I would like to jump from this pretty old firmware to such a new one, do I need to root, unlock it first and flash step by step newer Android version? or is it possible to flash the Coderom immediately (after root, unlock and probably a recovery installation)?
If a custom ROM is flashed, is the phone still SIM locked?
Modell GT-I9000
Firmware Version 2.1-update1

-------------
First I have tried to backup the important data from the phone (only contacts and photos).
Until now I could not backup the efs folder/partition. (probably I need root first, right?)
I could hardly connect Kies with the phone, but I have not got any data with it. And I got an initialise error if I wanted to update (so 2.2 or 2.3 was not possible). An info box showed to use Smartswitch.
So I have used Smartswitch on the Mac and could connect via USB to the I9000. I have seen public folders and made a backup of the contacts and pictures. An upgrade was not possible too. Thus, the 3 branded Android Eclair is still on the phone.
With "Vol.Up - ON - Menu" boots the recovery.
With "Vol.down - ON - Menu" boots the yellow construction figure state for Odin. (download)
No play-store on the phone. Only google market (where I have not found anything useful). I have searched on apkmirror and could not really find apps for Android 2.1.
---------
what would you suggest to do and in which sequence? (without windows)
- root
- unlock
- backup efs folder
- install clockwork mod
- format somehow f2fs ?
- flash coderom
(do I have to care about german language too? or are most distributions CM etc. multi language?)
thanks for any help!

It is strange, I have problems now to get into that recovery with the three button combination. Downloading modus works fine.
=>>> Now I got it....I must hold all 3 buttons the same time and wait 2 times for the Samsung logo. After that, I need to leave the power button but not the other 2. That starts the Samsung Recovery.

No carrier data after Odin stock restore [NEED HELP]

Hi everyone,
Noob here. I was trying to sideload the 6.0 OS and was having issues. The after many attempts, the install worked...but then failed the installation. After this, on the bootloader screen, I was getting the error "dm-verity verification failed" which some posts recommended re-flashing a stock image onto it to fix this. So I looked for a stock image of 5.1.1 and found a guide on how to do this restore. All of this part went fine.
Except now, everything is working but no carrier data. I have phone calls, wifi, etc. I will try to give as much information as possible, please let me know if you're missing some information I can provide.

Yowza. You're on BOI2 (old) build with newest official base band (BOJ9).
I think your best bet is to use ODIN to flash BOJ7, then follow the instructions in the update to MM thread - side load to BOJ9 then PD5 then PD6.
Everything you need is linked in the OP of this thread.

Thanks for pointing me to that post. I started the flash in Odin with OJ7, putting all files in their proper field. The flash failed shortly after starting. Now the device says "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC Software."
I installed and started the Smart Swtich software. The device is not listed in the Emergency Software Recovery list. I reinstalled the drivers a couple times, I can see the device in Device Manager and everything looks fine. How do I get out of this situation...
Every time I reboot the phone, it shows that same screen about the Emergency recovery.
Thanks

I could be wrong, but I don't think smart switch works for recovery on ATT models. Maybe take it to a best buy with Samsung store and see if they can get you up to full BOJ9?
Mucking around with Samsung software isn't my strongest suit - the s6 has been pretty locked down so I haven't played around much, and my last Sammy before it was an S2. Maybe someone more familiar can jump in.

I got it to work. I used Odin to flash each file, one at a time (since one of them was causing an issue). 3 of them worked. I then sideloaded OJ9, then PD5. I have PD6 left, but I'm sure it'll go well.
Thanks for your help mate
