[Xperia Z2 Original Android Development] iXaidyiu:
Permanent FIX:​

Before using the temporary fix below, you may want to try out this permanent fix.

-----------------------------------------

Difficulty? Simple as hell

But please note that doing these steps will completely wipe and reset your device, so please do backup before proceeding.

-----------------------------------------

What you need to do is to restore the device using EMMA, tap on the .575 (or .570) option and then install.

After the restoration is complete, fire up flashtool and update the firmware to .291.

Then reinstall this ROM.

The issue should be fixed once and for all.

==================================================

TEMPORARY FIX: Will be removed upon positive feedback with the above method.​

Since the initial launch of this ROM, users have been complaining about that they have trouble when connecting to 4G/LTE after disconnecting to Wi-Fi, so I made this simple temporary workaround for the moment being until I can find the real problem.

-----------------------------------------

Pre-requisite:

A device capable for 4G/LTE bands (NOT needed(suitable) for D6502 user)

Root

Time

-----------------------------------------

Steps:

Go to Google Play Store and download AutoMate.

Download the "script" I wrote HERE and put it anywhere that is easy to reach.

In AutoMate, tap on 3-dots menu on top right, click on "Settings", check "Run on system startup", "Device administrator", "Accessibility service" and "Usage access". No premium subscription is required as this "script" is set to be run for infinity (infinity loop).

In main screen of AutoMate, click on the 3-dots on top-right, select "Import", navigate to the file and tap on it.

Back to main screen of AutoMate, tap on "Enable system to renable 4G/LTE Connection" or something like that.

In this sub-screen, under

PERMISSION

, install the two permissions it requires.

Click on the "Start" button right above the

PERMISSION

section, then it will be running forever and the problem shall now be solved once and for all.

Discussion:

Q: How the battery drain caused by it?

A: No significant amount of battery drain by it observed after a day of real life usage testing (1/2 hr SoT difference between with and without), but may varies with different life style among different people. If you have out-of-barrier battery drain experienced, please revery back to manually method and report to me in this thread the presence and wait for another method found by me (or anyone else) you found battery-life-friendly.

Q: Any bugs?

A: One: WiFi has to be set to on when system start-up (and switch it off again if you intend to), otherwise manually trigger for Wi-Fi is needed.

------------------------------------------

Updates may come if I have discovered a more efficient way to solve this problem.
