[Q] Porting of other devices ROM on Grand Quattro I8552

Way to port

You can port any arm v7 cpu devices roms to arm v7 devices .

For porting basically u need two roms

base rom :: rom which u want to port to ur device (generally cm ports gives best results)

stock rom :: rom made for ur device. (u can also take backup of samsung stock rom by deleting data folder as stock rom!! but custom roms gives best results)



On your PC extract the .ZIP files containing the two ROMs and navigate to /system/app in your extracted base rom and copy stk.apk vpnservices.apk camera.apk and bluetooth.apk into a temporary directory somewhere else on your PC.

Now delete the following folders from your base ROM and replace them with the ones from your stock ROM: /data /system/app /system/framework /system/fonts and /system/media.

From your stock ROM copy /system/lib/libandroid_runtime.so to the system/lib/ directory of your base ROM overwriting the file.

Next up move the .APKs you copied earlier back into the /system/app directory of your base ROM.

Open up /system/lib in your base ROM and copy all the files and folders. Paste them into the stock’s /system/lib directory replacing all. Then go back to the base ROM and delete the /system/lib folder and replace it with the /system/lib folder from the stock ROM.

Next navigate to the /system/etc/init.d folder in the base ROM and do the same copy-from-base paste-to-stock delete-from-base copy-from-stock paste-to-base shuffle as before.

Sick of copying? Tough. Navigate to /system/etc/permissions and do that same copy-paste dance one more time.

Now open system/build.prop from both the stock and the base ROM in Notepad++. Update the stock build.prop to match the values for ro.build.description= and ro.build.fingerprint= from your base. Now save the stock build.prop exit Notepad++ and copy the stock build.prop into the base ROM overwriting the base build.prop.

Almost there! In Notepad++ open META-INF/com/google/androidupdater-script from both your base and stock ROMs. Edit the base’s script to be like the stock’s updater-script: specifically change edit or add the sections for permissions ui_prints asserts run_programs and installing the kernel. Don’t change any of the symlinks. In the base script make sure that the ‘format’ values are appropriate for your device (compare them to the stock script)..

It work's well for gingerbread,ics rom's.But little bit troubleshooting is required for jb and kitkat roms..

Try out grand roms

Try out to port from grand miui ports as in those dual sim is enabled..U can port from any arm v7 cpu devices..But better choose samsung dual sim devices for an easy port...
