[Guide] Install E988 Kitkat OTA Rom on AT&T E980

sandyiscool said:

Hi all,
I installed the E988 Kitkat stock (OTA) rom on my AT&T E980. The flashing went fine but there was no network/signal. 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.

Steps:

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 !!!

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 :

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

Okay so i have finally cracked the free space issue and solved it , the issue :- not seeing 32gb usable i.e. 23.3gb usable space
the cause :-
e980 mounts the internal sd as under /sdcard/
e988 mounts the internal sd as under /sdcard/0/

this can only be seen in recovery , strangely when in the os the default "0" is loaded and even if u choose to goto /sdcard/ you cannot it mounts to the "0" location , so the correct way to have the full usable space and the perfect non bloat rom as follows

1.Root and install CWM 6.0.4.4 or 6.0.4.5
2.Download the necessary files -
the CWM restore zip http://boxhost.co.uk/3u0c26iw2dyx/2014-05-19.06.05.14.zip.htm
the baseband zip - https://www.dropbox.com/sh/ty1ri9o81ejukx2/AACyCFnq2n3ph5WRclUH3369a
these are all the files you will need
3.place the files correctly , the baseband zip can be placed anywhere in the external sd, the cwm restore MUST be under your EXTERNAL SD card path being /clockworkmod/backup/2014-05-19.06.05.14/
Under that path you should see many files such as boot.img , if not you havent done it right.
4.power off the phone and take out your external micro sd ( this is a must)
5.Hold down the vol down + Power key - it will ask you to hard reset - confirm ( This will wipe out the internal sd )
6.Reboot to recovery by holding the volume up + power key
7.Insert external micro sd card
8.Choose backup & restore and restore from sdcard1 - it will give you and option of only one backup , restore it
9.wipe data , factory reset, wipe dalvik cache
10.install the baseband.zip
10.reboot to system

Enjoy & verify you have connectivity & storage should say Total Space 23.3GB , Available - 23.07 Gb

Tested on my Gpro , would request OP to update this guide , will help many a few.
