HOW TO PORT ROM FROM A DIFFERENT SoC!!!!!Works for-MT6589 to MT6577MT6582 to MT6572MT6577 to MT6575Only ICS to ICS & JB to JBMay also work with 4.1 to 4.2No Need of Source CodeNo Need of Kernel SourceNo Need of **ANDROID KITCHENNo Need of LINUX... [IMG]Requirements:* A Brain* Patience* Windows XP/7/8* 7-Zip* Notepad++* Bootimg Unpack/Repack Tools for Windows!* Stock ROM* And a Little Respect!!So now Lets Begin...PORTING For Same SoCs ( Ex: MT6572 to MT6572)* Replace these from your Stock ROM to the ROM u want to PORT!! Lets Call it "PORT"FILE LIST FOR REPLACING:*system/vendor*system/usr*system/lib/modules*system/lib/hw*system/lib/libncurses.so*system/etc/firmware*system/etc/vold.fstab*system/etc/vold.fstab.nand*system/etc/bluetoothFor Fixing Problems...*system/etc/permissions*system/etc/security*system/etc/audio*system/etc/wifi*system/lib/drm*system/lib/egl*system/lib/soundfx* Now Replace the Stock Boot.img to Port ROM!* Now Open The Port ROM folder and go to META-INF/google/android and open updater-script in Notepad++* Do the same for the Stock ROM* Now In the Port ROM's Updater Script, find a line that starts with this...format(".......and only replace the mmcblk0p.. with the stock one!* Do the same for this line...mount("...Example:This is the PORT one!!!format("ext4", "EMMC", "/dev/block/mmcblk0p5", "0", "/system");mount("ext4", "EMMC", "/dev/block/mmcblk0p5", "/system");This is the Stock one!!format("ext4", "EMMC", "/dev/block/mmcblk0p3", "/system");mount("ext4", "EMMC", "/dev/block/mmcblk0p3", "/system");Now just Replace the "mmcblk0p3" from STOCK to PORT!!It should look like this:format("ext4", "EMMC", "/dev/block/mmcblk0p3", "0", "/system");mount("ext4", "EMMC", "/dev/block/mmcblk0p3", "/system");DO NOT REPLACE THE WHOLE LINE!* Now go back to the Folder of Port ROM and You'll see 2 folders & 1 file named-META-INF-system-boot.img* Now Select these three and Click Right Mouse Button and Click on 7-Zip ->> Add to Archive* Now a dialouge box should appear!* Configure the Format like This:Archive format: ZIPCompression Level : NormalCompression Method: DeflateDictoioany Size: 32kWord Size 32* Now Start Zipping and Push the ZIP to your Memory Card* Go to Recovery >> Install ZIP & Wipe DataFinished!!Now was that so hard?? Its a Really Easy thing to d0!!Now Come to the Hard Part!!Porting From Different SoCs ( Ex: MT6582 to MT7572 )Read this carefully & apply the way i say!* Take the ROM u want to port & name it PORT!* Take your Stock ROM & Name it Stock* Now Replace These files from Stock to PORT--*system/vendor*system/usr*system/lib/modules*system/lib/hw*system/lib/libncurses.so*system/etc/firmware*system/etc/vold.fstab*system/etc/vold.fstab.nand*system/etc/bluetooth* Now Open build.prop in notepad++ & Search for this linero.mediatek.platform=MT65xxNow Replace this (MT65xx) with your CPU!!For Examplero.mediatek.platform=MT6572* Now Go To META-INF/google/android and open updater-script in notepad++* Add this line between the lines of "set_perm"set_perm(0, 0, 0644, "/system/vendor/lib/hw/gralloc.mt65xx.so");[Replace the mt65xx with your cpu]Example:set_perm(0, 0, 0644, "/system/vendor/lib/hw/gralloc.mt6572.so");* Now Go back to the Rom folder and Take the boot.img and decompile it with any bootimg-unpack tool!* Now delete the zimage and rename boot.img-ramdisk to PORT-Ramdisk* Now Do the Same for Stock boot.img and open the folder named PORT-ramdisk and copy all the files from PORT-ramdisk to boot.img-ramdisk of your Stock boot.img* Now Go to boot.img-ramdisk and open init.rc* Now find these lines and replace with your cpu#Create Chip Propertyon early_property:ro.hardware=mt6582setprop ro.mtk.hardware mt6589on early_property:ro.hardware=mt6589setprop ro.mtk.hardware mt6589example :#Create Chip Propertyon early_property:ro.hardware=mt6582setprop ro.mtk.hardware mt6572on early_property:ro.hardware=mt6589setprop ro.mtk.hardware mt6572* Now Compile
