Hacking SD2Vita not working please help

[lifeofmikey]

So I've had sd2vita for like a year now and every so often if I don't touch the Vita for a while or shut it off and come back to it everything is gone and config.txt basically resets itself for some reason(anyone know what?) but i always manage to get everything back by setting it back up. Well this time I couldn't. Nothing worked. And when I did input the games.skprx line it would just freeze at the enso boot logo. Well I decided I should upgrade to 3.65 enso so I did, everything went smooth. Now trying to get sd2vita to work and I can't. Re did the memory card zzblank thing. Tried the TF plugin and that still didn't work. It either reboots normally but nothing changes or it freezes on the logo

Tried on 2 diff SD cards (they're not fake or faulty) have the 1st Gen sd2vita (just ordered gen 5)
Can someone help me out. I just wanna play kingdom hearts! Lol
