@m@nish123 Thanks for a great guide, I was able to succesfully port the rom and it booted as well and after setting the selinux to permission my sims also started working but mic is not working, my device is MT6582 (Intex Aqua Speed). I have a working CM11 already ported for my device which is working perfectly fine. Also the soft keys (capacitive keys are not working nor even the power button). Please advise...

@m@nish123. . . . but mic is not working . . . .

The microphone is also not working in all apps (except Telephone where it work's fine) in the original CM12.1 by fire855 for the Kingzone K1. (The Rom this Porting Guide is based on).
That could be part of the problem.

But its not working in calls as well. BTW I am using @moonrotation build as my base. I haven't asked for permissions to port it yet. But that should be fine as far as I dont do the public release of it.

Tried to port this, Device reboots right after vendor logo

I compare stock Ramdisk with CM12. There are no diff. At end both have same values. I changed Kernel and Kernel Header

I changed the updater script so it fits to my partition. It gave me strange errors:

lsetfilecon of /system/lost+found to ubject_r:system_file:s0 failed: No such file or directory
m_file:s0 failed: Operation not supported on transport endpoint

Error flashing Zip : Failed
Updating partition details...

Also @michfood's tool just ain't work here, i took the v4 for my x64 win8.1. The Program is unable to extract the Ramdisk path, so i was forced to use "MTK Firmware Adapter Tool"

Recovery:TWRP 2.8.1.0
SoC:MT6592
Device: Doogee DG550

1. don't touch kernel header....change only kernel
2. u should try other recovery like philz
3. delete lost and found folder if present
4. use my meta-inf only....just change mountpoint of system........it seems u need good recovery with lp supported or philz recovery :fingers-crossed:

Thanks for guide.

My camera does not work and gallery does not see SD card.

How to fix it?

1. camera icon in launcher is issue (for mt6592)
2. for storage...fixes r from mt6592.rc in this file read proper sysmlink and do changes acc. to it ,decompile framework-res.apk....set sdcard1 as primary ,fstab changes also needed

I'm still struggling to port this rom to DG550.

1. The tool you used to extract the kernel does not work in Windows 8.1 and Windows 10 (I got empty RAMDISK folder). So I switched back to Windows 7 and it worked well.
2. Compared both Ramdisk folders in Stock DG550 Kitkat and Stock Kingzone K1 Kitkat boot.img's.
There is no difference except in ueventd.rc file. I tried to mix DG550 kernel and Kingzone Z1 stock Ramdisk with DG550 Kitkat rom. It didn't boot at first. The problem was in ueventd.rc file. See line 152 (Mali Node). After replacing ueventd.rc file from DG550 ramdisk it booted and worked well (stock kitkat rom). So both the stock ramdisks are identical if ueventd.rc file is replaced.
3. But it fails when porting the boot.img for CM12.1. Theoretically CM12.1 ramdisk should work with DG550 kernel for CM12.1 rom without any changes (except ueventd.mt6592.rc). It does not pass the boot logo.
4. Also I noticed that there's some issue in sbin folder in ramdisk.

Please let us know if u can let it boot

Ramdisk sBin shoudn't be a problem, if they really cause trouble, try copy the missing files from base dg550 kk to cm12
