[Q] boot loop problem on my 9005 with x note. topic

Hi everyone,

I am new to android and custom ROM's.

I rooted my phone and then installed x note 5.1 with the kernal that was recommended when i wend through the install process.

Everything was fine until my phone decided to do a security update and now my phone sometimes goes into a boot loop, If i boot the phone in my pocket it boots fine, but if i boot on the table it goes into boot loop.

How can I fix this, I really am not sure if i need wipe the data then re-flash my x note rom and start again?

I am a total noob and really value your help and advise in simple terms lol :D

Thanks guys!
Matt
