This is for any one who have lost their 2g signals/low signal/ or having just 3g signals
I had this problem after flashing VDT rom and lost my 2g signals and i tried what not i even tried to destroy my EFS partition, repair shops couldn't fix it even i got hopeless that my phone will ever work and was using my phone as PMP for a month but finally today i flashed Ice cream sandwich KDZ and i got my phone into working condition again.... have strong 2g + 3g signals
now the solution is pretty simple

Uninstall everything related to LG e.g. drivers b2c tool everything restart your Computer

1. you need to install latest drivers
2. Download kds flash tool (refer to this post for drivers and flashtool http://forum.xda-developers.com/showthread.php?t=2797190)
3. Download Ice cream Sandwich version for your phone
4. "This is important" Select CDMA
5. Select your kdz file
6. Select cs_emergency
7. Finally click on CSE Flash (it will flash and hard reset your phone)
8. Don't change country or language
9. After extraction you might get error "Unable to connects to server try later" ignore it, process will continue under it,
10. Your phone will restart and boot into ice cream sandwich.. now put in your sim and restart phone again and Voila you got your signals back

why this works ?? because icecream sandwich had a different partition scheme as compared to 4.1 jellybean onward, so it Formatted my EFS and it re partitions the whole storage if you are lucky you might recover your IMEI too stored somwhere in you EFS.. IF you recover your IMEI please share and help others... CHEERS!!!!!

Search for F180K30C_00.KDZ file, this is the latest official kit Kat kdz. But before flashing this again flash ics kdz to get your signals back.

No luck for me

I followed your instructions and installed the ICS ROM on my F180K, all installation progressed smoothly and phone rebooted normally but upon loading the sim and after reboot I still have no signal and on lock screen get service disabled. Any more ideas or suggestions? it is almost like the radio has been disabled

Further help would be much appreciated.

Best Regards,

Faraz
