Default CID Unlock rom etc. Help Needed.
He guys i'm goin mad about my htc universal.

I need help of you.

I want to ask lots of things. First of all i need to know about rom upgrade and downgrade. I did upgrade and downgrade nearly all of the htc devices. But i saw in topics friends asks how to downgrade. Isnt it enaugh to downgrade in bootloader mode or my jasjar is unlocked. Coz i did upgrade or downgrade several times. But people have still problem about downgrading. What is its trick.

Second i need the most stable wm5 rom for jas jar. What didi you suggest to me. My device is tmobiles device but i think there is no differece with the other uni. devices like jasjar itwq etc.

Thanks for helps
