In this post I will tell you that how to port any MTK6589M/6589/6589T ROM to our Spice Mi-535.
But before porting the ROMs you should know that what exactly porting is.
What is Porting ?
Porting is the process of adapting software ( in this case any ROM of different phone having chipset MTK6589M/6589/6589T ) in an environment ( phone's hardware ) for which it was not originally written or intended to execute in. The term is used interchangeably when referring to the changes made to hardware when it has to be made compatible with other environments.
Due to the difference in the hardware of the both the phones ( from phone it is extracted and to phone it is now going to install i.e. in this case Spice Mi-535 ) except Chipset , we need to replace/edit/add some system files from the stock ROM of our device ( Spice Mi-535 ) with the system files of the ROM which we want to port.
Requirements for porting the ROM to our device ( Spice Mi-535 ) are
.
1. Android Kitchen
Go to this link to download and install Android Kitchen in your PC.
.
2. Notepad ++
Download the Notepad ++ from this link.
.
.
3. Stock ROM and Downloaded ROM ( ROM which you want to Port ).
Download the Stock ROM of Spice Mi-535 from this link. Use this link to extract the System.img of the stock ROM. You can use this or this ROM also in the place of Stock ROM. You can also use any other ROM i.e. ported for our device ( Spice Mi-535 ) in the place of Stock ROM. But better will be the above options.
You can download different MTK6589M/6589/6589T ROMs from the websites like www.needrom.com , www.chinasmartphonereview.com , XDA Forum. There are many other websites also but I am giving you the link of famous websites.
# Steps for Porting the ROM to our Device ( Spice Mi-535 ) #
1. Copy the two ROMs ( Stock ROM and the ROM you want to port ) to
C/cygwin/home/Username/Kitchen/original_update
2. Now Run Andriod kitchen & select 1.
3. Select Stock ROM and give the Folder name i.e. WORKING_Stock. Now ROM will be extracting. After this , Keep updater-script (Edify) format.
4. Again select 1 option and extract the ROM ( that you want to port ). Give this Folder name i.e WORKING_Port. Again keep updater-script (Edify) format.
4. Again select 1 option and extract the ROM ( that you want to port ). Give this Folder name i.e WORKING_Port. Again keep updater-script (Edify) format.
5. NOW you will be having two extracted ROMs i.e. WORKING_Stock ( C/cygwin/home/Username/Kitchen/original_update ) and WORKING_Port ( C/cygwin/home/Username/Kitchen )
Copy/Replace the necessary files from Stock ROM to the ROM you want to port
Now open two ROMs in separate windows.
1. Delete the folder firmware folder from " WORKING_Port \system\etc " & Copy firmware folder from " WORKING_Stock\system\etc " to " WORKING_Port\system\etc ". Fix gps.conf ( WORKING_Port\system\etc ) by changing the first line to in.xxxxxxxxx or just simply replace/add this gps.config file.
2. Copy all files from " WORKING_Stock\system\lib\hw " and replace with the " WORKING_Port\system\lib\hw ".
3. Copy all libaud*.so files from " WORKING_Stock\system\lib " and replace with the " WORKING_Port\system\lib ".
4. Replace libcamalgo.so and libcameracustom.so files from " WORKING_Stock\system\lib\" and replace to " WORKING_Port\system\lib\"
5. Copy mtk_stp_wmt.ko and mtk_fm_drv.ko file from " WORKING_Stock\system\lib\modules " and replace with the " WORKING_Port \system\lib\modules ".
Do some necessary changes in build.prop and updater-script
1. Open the WORKING_Port ROM build.prop and make changes to these lines as given below.
ro.product.model=Spice Mi-535
ro.product.brand=Spice
ro.product.name=Mi-535
ro.product.device= Mi-535
ro.product.board: Mi-535
ro.product.locale.language=en
ro.product.locale.region=US
ro.sf.lcd_density=240 (If this line is not present , then leave this)
ro.build.display.id=xyz
(You can change this xyz to anything , but sometimes it creates issues as some ROMs are having OTA support. By changing this , you can face issues regarding OTA update )
2. Open the updater-script using notepad++ from " WORKING_Port \META-INF\com\google\android and verify that system should be mounted in "/dev/block/mmcblk0p5" & /data should be mounted in "/dev/block/mmcblk0p7".
For more information on updater-script go to this site.
If you want to add Aroma-Installer , then go to this and this site
Now some changes in boot.img ( Very Important )
1. In Android Kitchen select "0" and "12" and "w" (It will extract boot.img from WORKING_Port to Kitchen\BOOT-EXTRACTED)
2. Now select "a" and then copy the boot.img from "WORKING_Stock" to "Kitchen\bootimg_mmddyy_hhmmss"
3. Now copy zlmage from "Kitchen\bootimg_mmddyy_hhmmss" & paste to "Kitchen\BOOT-EXTRACTED"
4. Go to the init.rc file inside extracted boot.img and find (ctrl+F) “cam”. Add more lines (If present) related to camera from stock boot.img init.rc to WORKING_Port ROM boot.img init.rc.
5. Now select "b" option in Android Kitchen (It will build boot.img from BOOT-EXTRACTED).
Now everything is in place , its time to build the ROM
1. Select "99" option and then select "2". You can select "1" also but option "2" will make ROM automatically (including naming of the ROM zip). By option "1" , you can set your desired name.
2. It will automatically create ROM in "Kitchen\OUTPUT_ZIP" after 3-6 mins.
CONGRATS.
