my phone was AT&T g pro that is E980 with an android version 4.4.1 and i updated it to 5.0 with a kdz of 240L that is U+
at the end of the CES flashing (done of flash and installation of apps) i realized that my network signal is down that means no bar of a net signal but always searching for networking .so with this problem i decided to return to my old AT&T operating system ,in which i still faced the same network problem that i had after CES flashing of the kdz file. but before U+ i was having full network .please any help
bro.... i did the exact same thing u did. what i read in several other post was some people figured to solve the problem by flashing our g pro e980 with the mexico telcel e980 kdz to get the signal fixed then flashed the g pro e980 att TOT image. i tried but no success with my phone. give it a try, i hope ur phone gets fixed.

Check your IMEI. Probably corrupted EFS partitions... I really hope you have a EFS backup.

is there a way now for lg optimus g to change baseband?
I bought LG optimus G F180K (KT version -olleh), I'm from Philippines btw. I can't get 3G even with the original device setting. I flashed E975-10a firmware which I downloaded from the LG site for firmwares. I'm sorry I'm noob about this. I flashed the KDZ file without unlocking the bootloader, is that ok? Anyway, everything went well, but still I only get 2G signal. I think I need to change the baseband in order to get 3g or 4g. HOW DO I DO THIS?
Thanks!
Edit:
BTW my current baseband is APQ8064/MDM9x15M
kernel: 3.4.0
build #: JZO54K
I read somewhere in the forum that after he flashed the E975 firmware on his F180L device, he then flash the orginal baseband for F180L. Can someone provide a flashable baseband for F180K? I would greatly appreciate it.
I got this from another thread

Sure, you must do this.
First: Root, Enable USB Debugging, Download this file: (I can't post the link since I have less than 10 post as of now)
2. Copy this baseband.img to Internal Storage (/sdcard)
3. Run file flash_baseband.bat
4. Follow the guild.
5. Your phone will reboot and finish! :victory:

Here they simply flash the baseband. Is there someone out there who would generously share the how to flash the baseband for F180K?
i own an lg optimus G e970 at & t version on ics
i rooted it.... installed slick JB on it http://forum.xda-developers.com/show....php?t=2084431
but forgot to install the modem via recovery.... so when i turned my fone ON, i had carrier network signals available but wifi was not working....
i downloaded a KOREAN kdz for f180L and tried flashing it on my e970 via R n D tool...it was successfull but when my fone rebooted, it was country locked (required some password at the beggining)
so then i started looking for the other kdz,s available online (as i was specifically looking for kdz for at & t LGOG)
then i found a brazilian kdz for e977 and flashed it to my fone via R n D tool and my fone booted up.....everything working but no network signal showing a sim error icon in status bar
edit 1: finally i got the LGNPST to work and flashed the stock at & t rom but still it shows "no sim card"
flashed a different jb radio...its getting weak signals
working on it now
may be need efs

Lg g4 h815 .No service. Need help pls
I am from india. I recieved an international version lg g4 h815. Software version H81510h. I upgraded to H81520L MM using LGUP. After that I'm not getting network. The mobile network option in settings is inaccessible and not highlighted. The phone works perfectly appart from that. I tried searching the issue. I guess it has something to do with the change in modem after update.
Its a case of very low signal reception. I can get 50% signal where it used to be 100. And no network where i used to get 50% network. Anyone solved this issue?
Check your imei i suspect that your modemst is corrupted..
