I temp rooted my evo shift using visionary. And tryed to flash my kernal n failed, I want to know do I have to be perm-rooted to be able flash my kernal!!!!??????? I JUST WANNA OVERCLOCK MY EVO SHIFT using set cpu!!!
Also I used rom manager and attempted to flash my kernal but failed.
I'm no expert but I'm going to say that it isn't possible. Achieving perm root is really not that difficult as long as you can follow instructions. Check out the ROMs and hacks section for a breakdown on the whole process.
Ditto on the perm root. I just did it the other day and I can tell you that, while yes you do have to follow all steps exactly as written, that is generally the case with anything involving rooting/flashing/etc. I found it to be a much easier process than I went through with my Hero back in the day before there was a one-click option for that phone. Or maybe it's just the experience I've gained since then...
