For some HTC Evo 3d users with HBOOT version at 1.5, flashing custom kernels is pretty much impossible with your standard recovery install. Due to updating the HBOOT to 1.5, you are forced to use HTC”s bootloader unlock method which opens up custom rom installs, but locks down the any boot partition modification. In layman’s terms, this prohibits all kernel installs.

However, there is a way to get around this. The below steps will assume you have ADB and Fastboot tools installed and ready to go. If you do not, please download it at the bottom of this post. This also assumes you know a little on how to use ADB and can follow basic command line directions.

I used the below method to flash Android Revolution successfully on a CDMA Evo 3d with HBOOT 1.5 — rom and kernel.

Note: this should be fairly painless, but problems always have a chance of occuring. You are on your own if you brick your device.

1. Set up ADB/Fastboot tools and make sure the command adb devices shows your device. If this is your first time, grab and install the fastboot drivers from here.
2. Ensure your Evo 3d is on HBOOT 1.5 (volume down + power from a powered off phone) and has been unlocked via HTC’s unlock method.
3. Time to flash your desired recovery. I prefer TWRP, which can be downloaded below. Place this recovery.img within the directory that ADB and fastboot tools reside in.
4. Boot your phone into the bootloader (volume down + power).
5. Select fastboot.
6. Connect your USB and issue the command fastboot flash recovery recovery.img. This will flash the TWRP recovery onto your phone. Do not reboot or exit out of the fastboot screen.
7. We will now fastboot into the recovery instead of using the two finger salute. HTC will give write permissions thru the recovery to write to the boot partition via fastboot. Issue the command fastboot boot recovery.img. This will boot your Evo 3D into the TWRP recovery.
8. With your favorite rom or kernel on your sdcard, you can now successfully flash them thru TWRP.

One of my favorite roms on the Sensation 4G is Bulletproof 1.4, based on Sense 3.0. It has the right mix of tweaks and mods to make it smooth and quick in the heavily populated world of S4G roms. However, one thing that was missing from the rom is the ability to wake the phone via the volume buttons. The version based on Sense 3.5 has it, but not on this Sense 3.0 version. So like any rom junkie, I ended up messing around with the android.policy.jar file and manage to smali/baksmali edit the file needed to make this happen.

For your enjoyment, download the zip below (log in first) and flash it via your recovery. Cache wipe isn’t necessary but it won’t hurt.

There is no guarantee that this will work with any other rom. It’s also highly suggested that you back up your /system/framework/android.policy.jar file or just run a nandroid on your existing rom. This was done entirely on a stock BP 1.4 environment and has been tested on this rom specifically.

PS: If you have another rom you’d like this mod done on, I can run the edit for you. Just let me know what rom and what Sense version etc.
