I know im a complete noob and probably did something stupid and also that you senior members hate stupid post here but please I really dont understand what happened....Also I have tried to flash golden eye rom over again and it is just going black and shutting off mid flash...I tried making a new rom slot to see if maybe i could just flash rom on new slot but no luck. I have looked EVERYWHERE and havent found anyone that has had this issue,lol which add to my feling of stupidity...ANY IDEAS???
You did not mention your phone firmware but based on your post, your firmware might be NB1 or NC1 since you said that you successfully installed the safestrap 3.72.
You did not mention which version of GE you flashed but I guess that might be GE28 or later. If you did, those roms are based on KitKat (android 4.4.2)
You flashed the hyperdrive15 which is written for jelly beam (android 4.3) based on the rom for the MK2 firmware.
GE rom installation for safestrap did not mention to install the rom in the different slot, so I guess you installed the GE rom in the stock slot.
Hyperdrive15 installation for safestrap mentioned to create/switch slot so you may or may not install the rom in the stock slot.
As far as I know, safestrap 3.72 does not support extra rom slot other than the stock rom slot. It appears that hyperdrive instructions were written for the safestrap 3.71.
May be that was your mistake.
My suggestion been odin the stock rom that corresponding to your firmware. Use tworl root to get rooted.
