So, I've flashed about 3 ROM's. Jelly bean's ROM, PAC-Man ROM and Team Carbon's ROM. Recently I just flashed Team Carbon's Nightly March 17 ROM build. After that, my 4G was completely gone and my single was acting weird. Wasn't showing Verizon Wireless in the toggles in the notification panel and wasn't getting a data connection at all, also wasn't getting any single bars for regular cellular connection (phone calls and text). But was able to place calls and such. I noticed this when I was about to turn on tether.
I've done my research, tried all possible solutions to the best of my knowledge and still, nothing. Has anyone had this issue before? I've seen one other post by someone who has the same phone and their thread didn't come to any resolution. There must be a fix. Can ROM's edit the sim card data? How can I force to activate when the phone won't let me? *228 won't let me.
I've already tried restoring to stock, factory reset from the stock settings and from TWRP (2.4.4.0). I have plenty of TWRP backups and tried them, but nothing seems to work. I'm betting the data on the sim was changed somehow and I know I did not do this intentionally. How would I?
I really do not want to call Verizon and have to get a new sim card, if they'll even give me a new one. Of course, I won't tell them I've been flashing ROM's and have unlocked my phone. But still.
[Edit] Corrently returning to stock via odin and am going to run a hard reset code. - Didn't Work. *2767*3855# doesn't work on Verizon Apparently.
So I was trying some new roms (CM11, temasek, etc) today and I got an error when flashing an old 4.1 samsung rom (I was on 4.3 official yesterday).
Now my SIM card is not recognized. It says "only emergency calls" and nothing else. I don't have cell signal at all.
I tried taking out the SIM and putting it inside again and factory reset in CM. I also tried flashing again the 4.3 samsung unlocked rom.
I'm downloading right now the 4.3 official rom from Vodafone (my carrier), in hopes that will fixed it with ODIN, but just to be sure I'll ask if anyone knows how to fix this issue.
Thanks!
Hundreds of identical posts, search and read before starting new threads.
If flashing the stock 4.3 rom with odin doesn't work then you'll need the backup you made of your efs folder.

Music from SD Card
I just flashed the rom on my e970 and everything works including the phone seeing the SD Card but I can't get any music player to read the music that is on the sd card. Any help would be greatly appreciated.
Use sd scanner app from play store, that works fine for me.
Will this support Mod kernels? I think that's what I want to say but I'm not a complete Android geek.... Yet

Upgrading to CM12 Lollipop
Hi, I'm trying to upgrade to Lollipop from this ROM and at first while flashing the CM12 zip i encountered the error "This zip is intended for gee, geeb" etc. So, I tweaked the updater-script and removed the assert and ran the script which installed the ROM but I'm unable to install the Google Apps. I tried with all gapps packages (minimal, micro, full), but none of them works. Can you please help me out?
Does this have anything to do with build.prop? Even though I flashed the fix to show as ATT e970, the CM12 updater-script identified this device as "geehrc4g"??Also, build.prop has some lines like
ro.com.google.cliendidbase.am=android-kt-kr
ro.com.google.cliendidbase.am=android-kt-kr
Do you know where can I find the exact build.prop for e970 (Kitkat)?
Device: LG - e970
Recovery: TWRP 2.8.3.0
is all good w the e971 and this rom?
Hi, just wondering how everything functions on the e971 with this rom? Flashing roms is new to me and am so bummed to finally receive word from Rogers there will be no official update for this device which is in my opinion unacceptable buying a flagship device and getting only 1 update for it 6 months later when the phone manufacturer has updated it, I'm done with them, anyways some help would be appreciated as I need my phone to function properly, I am on official JB 4.1.2 from Rogers, I have unlocked the device to be used with any carrier, now I am planning on rooting using the zv9-zvb universal root method, i was then planning on unlocking bootloader using freegee and then using freegee to install cwm phils touch and then gonna install this rom, anyways are those the propper steps and if I so will all functions of my e971 work as they should with this rom?
Also if i need to go back will it be as easy as downloading paulicats rogers 4.1.2 zip and using cwm to install it and revert back? Any help would be greatly appreciated and if your ever in my neck a the woods I'll buy ya a beer. Thanks.
Working fine for me
This is my first android device so I was attempting this for the first time, I was on Stock JB. First I Rooted the phone(universal root kit), unlocked its boot loader(app from playstore), was taken to cwm, tried to flash the ROM it didn't work a status 7 error occurred, then I flashed philz recovery, flashed the ROM again and its working fine.
I am new to this android world so this may sound noob but is there a way to backup my apps only so that I don't have to re install them every time I flash a new ROM. (Will be trying a lot of roms from now).
lg optimus g e971
When flashing the kittkat do I need to us cwm and be rooted
how to flash e970 stock ROM!
I tried it by installing zip via cwm recovery but it says error in zip.
Flawless Installation
I just installed this ROM on my LG Optimus G E971 and the entire installation was simple and flawless. Prior to this ROM, I had [ROM][5.1.1] [GEEB] [Mako base] Unofficial CM-12.1 which is a great ROM too, however, I wanted to try something that was based on stock. I have the latest version of CWM for LG Optimus G E971.
This is how I installed the following ROM:
1. Downloaded the ROM onto my phone
2. Booted into CWM recovery
3. Wiped data/factory reset
4. Wiped cache Partition
5. Installed ROM
6. Rebooted
Once I have used this ROM as my daily driver for a while, I will get back and share my opinion and thoughts about it.
I stumbled on to this rom and I must say it is very good. There are only two issues I am having that hopefully someone can help me out with. The first issue is an annoying data network setting prompt that happens when I boot up which tells me that I will incur additional data charges. There is a setting under mobile networks that is checked called "ask when data connected" Whenever I try to uncheck it it reverts back to being checked. The second is under access point names. There are two other apn there that I cannot delete for some reason. Does anyone have any ideas how I can resolve these issues?

Mobile network not working
The only thing that doesn't work is data/mobile network connection. I can make calls and receive texts, but data doesn't connect. What are some fixes I can try?

Try flashing the jellybean modem and see if that fixes the issue.

Just straight on top of the rom, or should I do a fresh install?
EDIT: Also are there different versions of the modem? This post only has one: http://forum.xda-developers.com/showthread.php?t=2220048

Yes the one you have linked to. Just reboot into cwm or twrp which ever recovery you have and flash it. Once done reboot.

I tried flashing the modem, but it doesn't seem to have any effect. I'm still getting this error (i.imgur.com/Ds2sHYc.png) and everything works the same as before (but at least nothing new is broken).

I'm not really sure what APN is, but after Google-ing it I found this on AT&T's support site (att.com/esupport/article.jsp?sid=KB424489&cv=820#fbid=lMQAN_Ixyrx).
I don't know what it did, but following the instructions fixed the problem
Thanks for the advice
Hello, thanks for clicking. After a bit of trouble (thought the rom was 4.4.2, flashed wrong gapps multiple times), I was able to install a nightly installation of Liquidsmooth for the Samsung Galaxy SIII (AT&T), however the phone is unable to detect the SIM card, telling me there is no SIM card, and emergency calls only. I have tried removing the card and putting it back in a few times, and have tried rebooting, as well as messing with the settings, and "Googling" fifteen times in desperation. I have even tried Does anyone here know a potential fix?
Unfortunately I was not able to post the URL to the nightly itself, but it's at drdevs,com if you can find it.
Also have tried reflashing the rom and Gapps, to no avail. If someone knows a modem, or a patch I can install, please let me know, it would mean worlds to me to be able to have a running 5.0 rom with no problems.
Hello there,
I have just recently flashed CM10.2 after I went through a lot of **** as a beginner.
Thanks to blueether's help.
Anyways, I have no connection on my phone, It detects and reads tmobile, att, etc... I try to connect to them and it just doesn't work. It says; (invalid card - Emergency calls only) Even though it worked an hour ago on stock rom so I know it's not the simcard.
Anyway or anything that I can do to fix this issue I am having?
I have dual custom recovery installed philz&TWRP so I could flash anything if needed simply.
Please get back to me on this. Thanks.

CM10.2 will have real issues with the new baseband that you have. You will want to run cm11 or other 4.4.4 ROMs

Yes indeed you're right after what I saw today.
Now let me ask you though, where could I get the baseband drivers?
Cuz even on cm11 that I tried today, there was still no sign of any connection, I even updated to the latest one.
Any ideas? /:
