[B]Ok I did a root with unevoked 3 and everything worked fine. The problem is when I downloaded the Cyanogen 3 Rom and installed it. It was loading at the boot screen with the blue droid and circling arrow and is kept lapsing. So I turned the phone off and when I turned it back on it went to the white HTC EVO loading screen and thats where I am. I tried installing PC36IMG.zip and it says "Main version is older! Update Fail!" I can get into recovery. I can connect through USB through that. I also wiped Dalvik and the cache. I need an Expert to help me out!! I need this phone for work...B]
When I first installed Warm TwoPointTwo, the white screen happened to me, too. I pulled the battery and then restarted my phone back up and it loaded then. Cyanogen is currently on version 7 over at http://www.cyanogenmod.com -- maybe version 3 is the issue? Try downloading the current version over at their website and flash that instead...
EDIT: I think in my case it's rebooting out of RA Recovery... everytime I do it freezes at the white screen and I have to battery pull and it's fine after. Clockwork Recovery never did that, but I don't like it all that much because they removed Edify... what recovery mod are you using?
Ok Wipe data, cache and dalvik cache and reflash the Rom then the gapps and reboot. That should fix it. Anytime you switch roms (unless its an update to the same rom or that dev says to) you need to do a full wipe.
Don't feel stupid. Its all good
EDIT: For the PC36IMG.zip rom you have, you might want to change the name or make a folder for it on the sd card. Because, if you go back to your bootloader screen it will scan for it. If you hit yes by accident then it will load that rom. Just a FYI.
Am I the only 1 having trouble with the Kinged Kingdom V1.7 sense 3.0 ROM frm kingsrom.com ? It doesn't power on wen u reboot so u have to take the battery out n put it bak in then turn the phone on even after u flash the ROM. V6 n the update frm v6-v7 works just fine with no problems. I like these tons cause they is super gud on memory.
