First off let me say I'm new to root. I rooted my evo last night by following the 2.2 root video guide. Now I'm looking for a rom and kernal that's right for me so please be patient with a noob.

Can someone explain to me (in noob terms please) how to install a rom and kernal. If there is a video guide that would be great. I assume all roms will come with the same files so once I learn how to do it I should be set.

Thanks in advance for any help you can provide.

Please use the search tool. Most roms in the development forum say how to also.
And check the sticky in the same forum.

PEOPLE USING AMONRA RECOVERY THE ROM AND KERNEL MUST BE ON THE ROOT OF YOUR SD CARD. ONLY ON CLOCKWORK RECOVERY CAN YOU SCAN THROUGH FOLDERS TO FIND YOUR ROM/KERNEL. SOME PEOPLE SWITCH RECOVERYS WITHOUT REALIZING SO TO BE ON THE SAFE SIDE I SUGGEST PUTTING ALL ROMS/KERNELS ON THE ROOT OF YOUR SD CARD. ALSO, WHILE ON AMONRA RECOVERY TO GO BACK A MENU/SCREEN YOU MUST PRESS VOLUME DOWN AND VOLUME UP AT THE SAME TIME.

1.) To install a new ROM you first have to download the said ROM. (Obviously.) Second of all, you have to find the kernel you want to use. Most ROMs come with kernels but you can still download the kernel of your choice.
2.) Once you have the ROM and kernel of your choice, go into recovery mode by powering off your phone, turn it ON WHILE HOLDING the VOLUME DOWN button, do not let go of the volume down button until you're at the boot screen. Select "Recovery" by pressing the VOLUME DOWN button and selecting it by pressing POWER.
3.) You're now in recovery mode. Make a NANDROID backup (varies on how to do it depending on which recovery you're using) if you're on Clockword Recovery scroll down until you see something saying "nandroid" when there select it with POWER, then select the option that says "Backup". (Not sure how AmonRAs recovery works exactly.)
4.) Wipe data/factory reset twice, wipe CACHE twice, wipe Dalvik-cache twice. (Dalvik-cache is located in "advanced" in the main recovery screen.)
5.) Choose "install zip from sd card" then "choose zip from sd card", press up once and it'll bring you to the bottom of the list and you should see your ROM, select it, then install it. Once done installing, go back and reboot your phone, it should be all done now. IF, IF, IF, you have another kernel, after installing your ROM, re-wipe CACHE and DALVIK-CACHE, THEN install the kernel.

You're all set.

Ok simple enough. Thank you for the info. Can I download the rom directly to my phone from this site or do I need to download it on my computer and move it to my sdcard?

You can download it from your phone, but make sure it's on the ROOT of your sd card. I prefer downloading it from my PC, then putting it on my sd card.

So you mean make sure its on the sd card itself and not in a file like downloads right? Also can I delete the PC36IMG file so it doesn't do that update check every time I go into bootloader?

Yes, make sure it's not in a folder like "downloads". And yes you can ditch the PC36img.

why cant ROMs be in a folder? i have flashed a dozen ROMs that are all in a folder.
Depends what recovery you are using. Ra recovery has to be in the root folder of the SD card. Cwr you can actually go through folders and search for the zip. So it wouldn't matter where you out it on SD card for clockwork but If ra recovery and its in a folder in SD card you won't see it and can't search through folders for it.

No problem :) just trying to help out.. I used Cwr then found out the delvik wipe didn't work. I had my SD card organized. Had my roms and kernels in a folder. Switched to ra recovery and couldn't find them. Realized then it had to be in root folder. Thought somehow I lost them during the process. I have a backup on my pc also just in case.
