It worked for you? Well i've seen many many f180k facing the same problem.. Over lgveit there is some kind of solution but can't understand the translation how it will work :(

Btw thank you for the share...

Yes it worked perfectly just for the 2g signal. It was nice and strong. No 3g however. Please notice that you MUST have your imei changed after the efs restore on order to assume that it did well. If your imei is unchanged then the efs restoration did not complete.

By the way I have an E975 not an F180

Do you have IMEI backup? Flash back firmware same as time you backup IMEI, restore IMEI, restore baseband then Hard Reset, everything will fine!

Dont worry. You just have to flash f180k official rom and after that root it
And install fx fjle explorer and its root addon after that open fx file explorer and select root and then go to /system after that open build.prob with text editor
Change this :
Quote:
ro.product.model=LG-F180K
ro.build.target_operator=KT
ro.product.locale.language=ko
ro.product.locale.region=KR
ro.build.target_country=KR

ro.product.model=LG-E975

ro.product.locale.language=vi
ro.product.locale.region=VN

Bro You just have to Flash f180s kdz
After that Go to Setting>> networks>> CDMA SUbcriptions Tap on it and just change Nv to RUIM SIM
Reboot your cellphone And Your single will be Back :)

    Smae problem but didn't backed up EFS before signal lost

    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 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...
    Right now i am on Sling 2.2.2 using my phone as a PMP... Please help me!!!1 i am waiting for your response

    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??

    I am myself on Sling 2.2.2. Never used Fregee for EFS I'll share you Modem which i flashed and procedure for backing up EFS
