[EVO 4G Q&A, Help & Troubleshooting] _Burst_:
Being that XDA has great info but 5x the garbage, here is some knowledge if you are interested in having root access on your HTC Evo 4G. This may change in the future.

Brought to us by Toastcfh, so this has been known as the "Toast" method of root and is quickly becoming the only way to go if you want root access. So thanks to him and anyone who has helped in the process.

Note: This process will wipe all data from the phone, so you will HAVE to start from stock.

Steps to have root:

Step .1

No matter what version of stock you are on, download this file: PC36IMG.zip

This file can be found directly here: http://link.geekfor.me/rootedromzip

Original site and info here: http://xdaforums.com/showthread.php?t=690762

Now that you have this file, place it on the root of your sdcard. That means in your sdcard, and in no other folder. DO NOT rename this file. This will take care of acquiring root. But we are just getting started, so on to the next step.

Step .2

This next part will cover getting ready to use a custom recovery. This has be given to us by Koush and is known as ClockWorkMod Recovery. Major thanks to him and the devs behind ROM Manager for making this so simple/PC less.

Download this file: recovery-clockwork-1.8.1.7-supersonic.zip (file version may very)

The file can be found here: http://www.droidaftermarket.com/koush/recoveries/recovery-clockwork-1.8.1.7-supersonic.zip

Again, original site and info can be found here: http://xdaforums.com/showthread.php?t=699043

Now, with this file, you want to place this in the root of your sdcard as well. However, this must be renamed to 'update.zip.'

Note: This file must be named update.zip and remain in the root of sdcard to use regularly.

Step .3a

Here you will want to download whatever rom you want in zip format and stick it in the root of your sdcard as well. You will need this for later. Most roms now have the super user app so you will be good to run rooted apps.

Step .3b

There is a good possibility that whatever rom you just downloaded does not come with the newer radio for the phone. This is available in a zip as well. Again, put in the root of sdcard and save for later.

Download this file: evo.1.39.00.05.31.zip

All files should be in the ROOT of your SDCARD. Meaning not in any folder.

Now that the files are ready, we can begin to attain root access.

Step .4

First you must reboot the phone into recovery mode. To do this you must turn your phone on holding the Volume Down button and the Power button until a white screen comes up.

When this screen pops up, the phone will go into recovery mode and works automatically. Give it some time (~60 seconds) and it will ask you if you want to install PC36IMG.zip.

Step .5

When the phone asks you if you want to update, click the Volume Up button to say YES.

Allow the phone to work. Takes a couple minutes so take a little breather.

Step .6

Once complete, the phone will ask if you want to reboot the phone. Again you click the Volume Up button and respond, YES.

Allow the phone to boot and install the stock rooted rom. Once the phone has booted, do not bother signing in and everything as you will be doing it again very soon. But congratzi, you have root access! But only from Recovery mode.

Step .7

Power down your phone. And then, turn the phone on by holding down Volume Down and Power.

Step .8

This will send you into the white screen that is searching for PC36IMG.zip. When it is done, this time decline the update by pressing Volume Down. Then it will ask you if you want to reboot. Press Volume Down again and say NO.

Step .9

This will send you into a menu that you can actually control. Use the Volume buttons to navigate up and down. Use the Power button to select. Scroll down to 'Recovery' and press Power. This will reboot the phone with a black screen and a red exclamation point icon.

Step .10

From this black screen, press Volume Up and Power. This will send you into the real recovery mode.

Step .11

Once here, again use the Volume buttons to navigate and Power to select. Navigate down to 'wipe data/factory reset' and select with Power. This will wipe the phone and get you ready for your first rom.

Step. 12

Once that is done, navigate to 'apply sdcard:update.zip' and press Power to select.

Congratulations, you are now in the custom recovery of ClockWorkMod.

Step .13 and beyond.

This menu is a fully capable recovery. Although it takes some time to get to, here is where you flash any zip you want. I recommend you start with the rom, then the radio. It doesn't matter really. And if the rom comes with the radio then it is redundant. But flash to your hearts content and enjoy your rooted Evo.

To flash zips, navigate to 'install zip from sdcard' then select whatever zip you want to apply. Refer to the roms instructions for any specifics.

Enjoy!

Note:

-Notice I didn't say "connect to computer?" This really can be aquired completely ota if necessary.

-Later on you might want to rename PC36IMG.zip and store it somewhere safe on the sdcard and home computer. Not that you will ever really need it, but if you want to go back to stock, this is a semi-automatic way to do so.
