Typical First Post - sorry

Right, to cut a lonnnnng first post story short, basically, rooted my phone yesterday, went well, installed some rooted apps and was having fun, one app, 3D something, from Google Play. it asked me to restart my phone after setting superuser (i thought this was quite weird) anyway i boot locked my phone - got the typical "Samsung GALAXY Note GT-N7000" and the phone woundnt move from there, i can gt into vol+ home and power and vol- home and power still. so after some research i found i had to flash therelivant stock ROM using odin - so i did. and it worked. then at somepoint today my phone got stuck in a boot loop consisting of the GT-N7000 screen then the samsung spash screen. when i do vol+ home power, i get in red text "E:/error%20in%20/data/recovery_last_kernal_log.txt" - what does this mean? and how(if at all) do i fix it?

i have curently re-flashed stock ROM and vol+ home power & "wipedata/factory reset" and so far so good......

any help or shed light would be a great help

Phone is Samsung GALAXY Note GT-N7000
