Hey guys. I've got a rooted Evo 4g that has recently started refusing to flash anything properly. I'm running the Stock Rom, v. 2.3.3 and I believe the stock kernel 18.104.22.168. Lately I've been trying to find a kernel that might improve battery life. So far I've tried Godmode v.9, Netarchy 4.3.4, and Tiamat 4.0.8. Every time I wipe the cache/dalvik cache and install a kernel, the phone will only boot to the HTC screen. After a little while the screen goes black, comes back on and it reboots directly into Amon ra. I tried clearing everything then flashing a completely new stock rom with all three of the above kernels earlier today, and got the same result each time. Fortunately, I had a nandroid backup saved so I've got my phone working again at the moment, but I'd really like to know what might be going on... Any thoughts?
