I was running Sling 2 perfectly without any network error . Yesterday i flashed Superlite vdt and i liked that rom since it was faster than Sling. Issue i noticed was network won't work in 2G only mode and phone would not recognize network. 3G was working fine but once ill be out of 3G coverage phone will lose signals with No service or Emergency calls only . I flashed E975 h modem but it did not work. After that i flashed F180 k modem but it resulted in Service disable . Finally i restored my previous EFS backup and hurray it went fine . Very strong signals on 2G and 3G both. So if any one is facing this issue just flash your phone's respective modem and after that restore EFS . Enjoy .

Dear Ahmed Senior,

I just admire you always for your help and thanks a lot from heart for this beautiful post and solution.
Actually, I didnt back up EFS till from the first time i update the lh f180. Now can you please inform when i should backup my EFS, after flashing jellybean or after flashing the modem. Or is there any EFS backup from original rom for F180k in the thread that help me out.

Thanks lot in advance.


Regards

If imei number is not visible you can't make any backup. Efs is specific to phone so it's difficult for you to get it.

Your message mean that My phone is only suitable for 4G now...Not working in 3G as i have no imei.

But when i was reflashed my phone through LS970 and press *#06# then i found a serial. But in Phone settings IMEI = 0. The LS970 rom is icecream sandwich rom and it was CDMA. But I am in GSM/3G. Is there any way to solve the problem Dear. Please suggest me


Regards.

Dear Ahmad bhai i am having the same problem as yours,,. but in my case i didn't backed up EFS before flashing VDT Rom.. my IMEI is fine shows same imei as my sim jacket on *06# receiving 3g signals in my city area but I live in a village so not getting any 3g signals here... this is what i have tried..
1. Flashed KDZ 4.4.2, 4.1.2 no improvement
2. Flashed several modems (flashing F180k gives me no signal) all thaht i could find in flashable form
3. Tried flashing several roms CM11, 10.2, Carbon 4.4.2, tried tinybin recovery via LGNPST
4. tried several sim card zong, warid, ufone, telenor, mobilink none works...

Please help me my mistake was that i didn't backed up my EFS when phone was working fine i too it's backup after the problem occurred...

If IMEI number is being shown i think no need to worry . Just make a backup of your EFS flash modem for your device i, i guess you have F180 k,and after that restore your EFS. It should work fine.Actually you need to restore EFS backup even if IMEI number is being shown.

Yes i have F180k, I did as you said but still no signal even now it does not find any network at all.. here is what i did tell me if i did anything wrong..
1. Made an EFS back up using Freegee
2. In recovery mode wiped cache/dlvik
3. flashed modem of F180K for 4.4.2 Roms
4. Reboot restored EFS partition.
5. Rebooted after restoring EFS

Still no signal what I did wrong? can you share the modem that you flashed and how do you back up your EFS via Freegee or any other mean?? and how you flashed the modem??

I am not using VDT rom but Sling 2.2.2 can this be the problem??
