[Karbonn Titanium S5 ROMs, Kernels, Recoveries, & O] rjt.rockx:
Thanks for that. I'm downloading it now. Will test it in a few hours ...

Let me have a guess...

Android v 4.2.2

Based on Xperia v2 ROM ( from the A919 Tool app icon and the normal nav bar icons in screenshot no. 2, and also the background in screenshot no. 1 where a message is seen saying that " Actually I was bored with Xperia v2 ROM so I made this ROM. " )

Changed Framework apk and systemui apk

Added Samsung Apps like the launcher and calendar, etc.

Updated GmsCore.apk (or Google Play Services to be simple)

Did not edit and/or change the data folder

Followed any MTK porting guide

Did a quick port today ( from the date and time in the screenshots )

Better RAM management -- Tweaked minfree values would be my guess

Did not change the Flashlight app (TinnoLED.apk)

Brighter Flashlight -- Not as easy as he hoped. He would need some redirection of app processing power to the flashlight app to increase its importance, and thereby increase the flashlight brightness. I'm guessing he hasn't done that, so you'd better remove that line.

Did not change the default time zone in build.prop settings (It is set to phillipines time. )

Neat. Good attempt.

Bugs :

Transparent Status Bar

From the screenshots, it is apparent that the Status Bar isn't transparent. You mean that the background of the Notifications panel is transparent. Status Bar transparency refers to the status bar having the colour of the app's upper part. Like in the first screenshot, the status bar (the part with the battery charging info, network signal info, clock, etc.) should have the colour of the app. (like its background should have whatsapp's green colour while running whatsapp)

But, that is more of a misconception than a bug.

Here is a bug which he cannot fix.

3g support on both SIMs.

For that, you need hardware support. It is wrongly mentioned in the Xperia ROM v2 too. I have tried and tested that in almost all other ROMs like MIUI v5, Xperia ROM v2, Stock ROM, etc. and it all comes down to the same thing. YOU NEED HARDWARE SUPPORT FOR 3G IN BOTH SIMS.

A piece of advice : Do not bet that there won't be an bugs at all. Each and every ROM might have a bug that the developer might have overlooked.

Here are some things your friend might have done or should do if he hasn't done yet.

Changing the build.prop setting of ro.product.**** to that of Karbonn's from MyPhone Agua Cyclone ( Xperia ROM v2 was built on that phone's ROM )

Add Material Design Apps from Apkmirror like Gmail 5.0, Maps, etc.

Try porting Kitkat ROMs to Jelly Bean based devices by modifying the installation procedure to include the priv-app folder

Try porting CyanogenMod to this device

Help me in porting Carbon ROM and/or CyanogenMod 12 to this device.

Mention how he got the updater script to work properly and install the ROM perfectly in TWRP and Philz Recovery

Sign the ROM using ZipSigner app and then upload it.

Add more features to it

Here are a few suggestions :

Update the version of SuperSU and then install it.

Make the Xposed Framework built-in. ( Not to be installed manually after installing the ROM )

Pre-install GravityBox or XBlast tools.

Odex the apps folder for better RAM usage

Increase the wifi supplicant scan interval

Throw in some paid apps for free.

Increase the net buffer size

Add the X-Reality engine

ZipAlign all apks.

Add some more fonts ( other than Choco cookie )

Add more sounds for ringtones, audio, etc.

Mention all these to him, and if possible, ask him whether he could help me to develop other ROMs for this device.
