Hello, I'm very new to rooting, and need some help. My phone keeps freezing on boot up at the "htc evo 4g" screen when ever I try to flash a kernel. I found out that I need to wipe cache and Dalvik-cache, but everytime I try to wipe the Dalvik-cache, it just goes black for a little while and then returns to the previous menue. I assume that it did not wipe, right? Or is it freezing for some other reason? Thanks.
