Root [CDMA] [support] issues after htc unlock hboot 1.5+

What you need and should already have:
Android SDK
Java Development Kit
HTC Sync

HTC allowing to unlock our phones is great. Revolutionary has stated that they are not looking for root on Evo 3D 1.5 hboot +. They may find a way to downgrade the bootloader to 1.4 but I would not hold my breath.

While the HTC method unlocks the bootloader, you do not have S-OFF and full control of the system directly. Meaning if you boot into recovery through adb or quick boot or other options you can not write to the /boot partition of the phone. You will not be able to wipe this partition or restore nandroids to this partition either.

What does this mean for you?

This means they you can not flash custom kernels or roms with custom kernels or restore nandroids with custom kernels.
However, dont worry. Where there is a will, there is a way.

If you get bootloops and wiping and reflashing dont work and if you lose wifi or 4g this will fix all your problems.

It has been found that booting to recovery through fastboot will go around this problem.

first thing you need to do is familiarize yourself with android sdk. You installed this when you unlocked your phone. Locate adb and fastboot. In older versions od sdk, adb and fastboot were located in the tools folder inside sdk, but in the new version, adb is now in platform-tools and fastboot is in tools. So what i did is copied the contents of platform-tools into the tools folder so everything is there. With my coding it may be different than what you did so you may have to adjust commands to fit your needs.

First thing, download rom and kernel and put on root of your sdcard. By that, I mean not in any folders so if you open your sdcard you see the rom and kernel easily. (I know that twrp and cwm allow you to browse folders, but this helps in finding them)

Connect your phone to your computer, open command prompt how ever you like and cd to android sdk where your adb and fastboot are located.

Code:
cd c:\android\tools
next boot into bootloader via recovery or what ever method you like

Code:
adb reboot bootloader
Once you are looking at the hboot screen, your cmd should still be open to the android sdk directory

You will now boot into recovery via fastboot

Code:
fastboot boot recovery.img
Once this is done, you can flash away and wirte to the /boot partition


BUT WAIT, THERE IS MORE!!!!!!!!!!!!!!!!!

There has been a new development and there is another way.

Jorykrim has done it again

And here are the steps for using this app.

1. Download kernel you want to flash and place on sdcard

2. Open app and select kernel image

3. Browse to the .zip for the kernel

4. Tap Flash image

5. (optional) Reboot to recovery to flash a rom

(the previous info for joeykrim app was found here: Flash Image GUI)

If you have any questions, ask away
 
A tip, if you just navigate to the folder where you have your tools and shift+rightclick the 4th option down is "Open command prompt here" so you don't have to cd.
