[*]How to take logcat :
Getting to the point

1) Unpack boot.img , open default.prop
Change ro.secure to 0 , ro.adb.secure to 0 and ro.debuggable to 1..
2) Download adb fastboot essentials. 
Extract it .. Open the folder. Press shift key and right click.. Open command prompt
First use : adb devices
Type
Adb logcat > filename.txt
Check lines of E\, W\, F\
ROM will boot soon 
3) When the phone is in bootloop:-
As soon as adb detects the device
This means that the logcat will be same in the file named filename. Disconnect phone after 10-12 seconds.. That much log is enough... Guys port ROMs ... Take logsIn the log ,Check the files related to the errors and fix them one by one
