Stuck at intel logo (bootloader unlocked)

My phone:
- was Jelly Bean.
- upgraded normally to KitKat
- some time passed and it crashed.
- installed RSD Lite
- unlocked my bootloader
- flashed Jelly Bean stock firmware
- back to life
- one month later crashed again
- flashed the same ROM without erasing anything
- back to life
- two months later crashed again
- flashed the same ROM
- back to life for ONE DAY then CRASHED AGAIN GODDAMMIT
- flashed the ROM - only now it can't complete the boot at the end and ASKS ME TO MANUALLY BOOT IT. That was the problem I was trying to fix, RSD. I can't manually boot it.
- tried a different stock firmware, still doesn't work

Should I try erasing user data? Or a different ROM/MOD? Help... =(

Asus MemoPad7 Build.prop I(ntel BayTrail)

Hello Guys! I have overwrited my build.prop file with the buil.prop of Nvidia Shield. I hoped it will alllow me to play Need For Speed No Limits on higher graphics. Yea I was dumb, Nvidia got Tegra GPU and mine got something else :D

1)Can someone upload stock Asus MemPad 7 intel baytrail build.prop file? I accidentally deleted mine.

2) Does changing of build.prop allow you to fake device info and make apps detect your device as other one? For example need for speed no limits detect device info and set "recommended graphic settings" but i want to play on higher graphic.

Thanks!
