I realised that the modem of E988 and E980 are incompatible and that I need to flash the correct modem for E980. So, I needed to root,install CWM recovery and flash the modem. I did some searching around on xda and found the methods to root, install recovery and flash the modem. In this thread, I want to list out the steps I carried out to get it working so that it may help others who are struggling to get it right.

  1. Flash E988 Kitkat OTA Rom on E980
    Download the E988 Kitkat rom KDZ file from here :

    The instructions to flash the KDZ onto your device are in this thread (Thanks to hyelton) :

  2. Factory Reset after reboot
    When the device reboots after flashing, it will ask to enter a pin to decrypt. To solve it you will have to factory reset the device. Press the power button till the device powers off. Then, press the volume down button and power button simultaneously till the screen powers on. It will show instruction on how to factory reset. Press power button once and it will ask for confirmation. Press power button again and the factory reset procedure will start. Your device will reboot after that. On reboot, you can then proceed in the usual way you would after a factory reset.

  3. Root the Kitkat Rom
    Now, you need to root your device. I searched xda for a rooting method that will work with E988 4.4.2 rom but could not find anything specific. Then, I stumbled upon the method from the following thread and it worked !!!

    Thanks to jarari2

  4. Install CWM recovery
    To install the CWM recovery on 4.4.2, I downloaded G Pro Kitkat Recovery app from the following link and installed on my device :

    Thanks to hoangnova​ from lgviet forum

  5. Flash the E980 modem
    Download the correct modem that will work with E980 from here:

    Thanks to hyelton again.

    After downloading, transfer it to your internal SD card so that you can flash it through CWM recovery. Take care that you copy it to the "internal" SD card as Kitkat reportedly has problems with accessing the external SD card. Though there may be workarounds for accessing the external SD card, I did not want to get involved in those at the moment.

    After you transfer the modem zip file to internal SD card, reboot your device into recovery mode. You can easily boot into recovery mode from the G Pro Kitkat Recovery app that I wrote about in the previous step.

    Once you are in CWM recovery, flash the modem zip file as you would usually do and then restart the device. You should be able to see that the network starts working and your carrier's signal bars.

The only issue that I have observed till now with this E988 rom is that it shows the internal SD card storage from 32 GB to 16 GB.

If someone can point to some method to increase the storage to its original, it will be excellent. Otherwise, I do not really mind it for the time being. I am using this rom till the time a Kitkat OTA for E980 is released. Once that is there, I will flash that stock rom.

Hope this post helps someone
I tried following hyelton steps on my AT&T E980 running software version E98020g running KitKat, After reading your post at "" I was tried installing "India E98810E_00.kdz" downloaded from link posted by hyelton as suggested.

Infact I am able to root my E980, but when I connect to LG Flash tool(Downloaded from the link hyelton provided) the error I get is connection "problem with communication between Cell Phone and PC".

In my first attempt my phone was not rooted and Developer mode was not "ON"
Tried couple of times after reboots on PC installed drivers as required.

Could it be because of mismatch from the version i am trying to install (E98010E_00.kdz) compared to one mentioned in the forwarding post (E98820A_00.kdz). Or I should know something else.

I also read that their is some TOT method to do it and was also able to connect my phone E980, but I am missing the .TOT or .dz files and could not find one. Any help you could will be huge help.

Yes I am new and trying it first time because of my comfort with Android Stock.

Appreciate your help.

Hi guys, I got a nerve racking situation with the Unfortunately the process has stopped. Then my phones turns off. Interesting thing: this only happens when I connect to a Wifi spot or when I have my SIM in. If I turn off Wifi and have no SIM in, I can use the phone with no problem.

Actually I have been using the ROM described here for a while, until I took out my SIM for a few moments. Then it started happening.

I have LG E988. I did flash the 4.4.2, although I didn't do the modem thing.
As I said, until I took out the SIM, both calls and everything worked perfectly well.

What I tried so far:

-Fix permissions
-Reset app defaults
-Clear cache

Thanks for any help!!!
e980, e980h, kitkat 4.4.2
