Hi all, how r u?

Now I will described you about ROM porting method for MTK phone (same SoC )

See details below :-

You need to have custom recovery for flash your new created rom.

Note :- Stock Rom is :- Current Rom of your handset. (Flashable zip)

Port Rom is :- Which Rom you want to port. (Flashable Zip)

Stock Rom & Port Rom need to be same version of android. That means if your "Port Rom" is JB Rom, You need to choice JB Rom as Stock.​

1) First you choice a flashable zip rom for port which is same processor as your stock rom.

2) Extract your Stock rom in a folder & rename the folder to "Stock rom"

3) Extract your Port rom in a folder & rename the folder to "Port Rom"

4) Now open the "Port Rom" folder & "Stock Rom" folder side by side.

5) Now copy & replace "boot.img" from "Stock Rom/" to "Port Rom/" folder.

6) Go to "system/etc/firmware/" folder & copy & replace all file from Stock Rom to Port Rom.

7) Now go to "system/lib/module" folder & copy & replace all file from Stock Rom to Port Rom.

8.) Now go to "system/usr/keylayout" folder & copy & replace all files from Stock Rom to Port Rom.

9) Copy & replace "META-INF" folder from "Stock Rom/" to "Port Rom/" folder. (Optional)

10) Now create zip of "Port Rom" folder, flash it via CWM.

If your new ported rom not booted or stuck in boot animation, Try again with replace "system/vendor" folder from "Stock Rom" to "Port Rom".

That's it :)
