Galaxy s6 5.1.1 root stuck on Samsung splash screen

Ok so updated my stock firmware to 5.1.1 with smartswitch for my s6 sm920f model, everything went fine so decided to root it using Odin with unibase bog8 v2 image, root was successful at the time and was working perfect up until I had to restart phone, its now stuck on Samsung splash screen but can still access download mode and recovery mode, I've tried clearing cache aswell as restore but issue persists need a bit of guidance please :(

Newer ROMs hang at splash screen

I want to upgrade the ROM on my HTC Bravo from MildWild 14 to a newer version of Android (4.*), but whenever I try to boot into any of the new ROMs it just hangs on the splash screen (after 45+ minutes).

I've tried the following ROMs so far:
- CM 10.1 Chromium
- CM 10.1 VJ Jelly Bean 4.2.2 v6.3
- Beanstalk Release 6
- KitKANG v2.0

I have upgraded my recovery to TWRP 2.7.1.0 and have repartitioned my 2Gb SD card using the GParted method. The first partition is 385Mb FAT32 and the 2nd is 1.5Gb EXT4. I always do a full wipe before trying each ROM.

Is it the case that the JB ROMs require more memory, and is that why I'm not able to boot any of them?
