Just a little housekeeping before we start:
Please! If you have a question, do not post it in both downgrade threads. Doing so makes it hard to follow what you've already done. Many people frequently visit both threads and will see your question. Thank you for your cooperation.
All credit goes to Unknownforce for making it possible to downgrade the EVO 3D. I take absolutely no credit for the downgrade method. My aim in creating the HBOOT Downgrade Toolkit was to make Unknownforce's downgrade method as easy and painless as possible. Thank you to him and everybody else listed below.
See post #3 for:
- Full Step-by-step directions
- Bootable USB flash drive instructions
- Other useful resources (How to burn an ISO to a CD)
Important! Please Read this!
- This is for CDMA phones only! DO NOT USE THIS IF YOU HAVE A GSM EVO 3D!
- Test that your computer will boot the Toolkit before Bricking! Use the 'Check device status' function in the Toolkit to see if your phone is being recognized (USB debugging must be enabled on your phone (Settings -> Applications -> Development -> USB debugging).
See Unknownforce's thread for bricking instructions.
- Do not do this if you already have S-OFF! If you aren't sure whether your already S-OFF, boot into the bootloader on your phone (Power off -> Hold down 'Volume Down (-)' and the power button). If you see S-ON, you're fine. If you have any questions, feel free to post them inside the thread.
- Charge up your battery - know that you have at least a decent (even 50 or 60%) amount of battery power going in. It will save you a lot of frustration later.
- If you are flashed to a different carrier: you must keep a record of the settings for your phone, as they will be wiped when you do this process.
Again. This is less scary than it sounds! I promise.
LATEST VERSION (STABLE): (should work perfectly when burned to a CD; if a USB flash drive is used, follow the NEW instructions in the second post to make the drive bootable)
- Device Test now properly states how to start the test
- Device Test does a Fastboot test, and an optional ADB test
- Help option gives a brief overview of the Downgrade process
- Some more information given before doing tests
- Downgrade will no longer snap back to the main menu after finishing

Personal thank you to the Revolutionary Team
Thanks to everyone who tested the CD and reported their findings.
If I forgot someone, please PM me, and I'll add you to the list.
I will also quote Unknownforce's thank you list, as I'm pretty sure that most of the programs in the downgrade CD method have some relation to them.

What is this?
This is a Live-Bootable Linux-based CD that attempts automates many of the steps that are required for the downgrade process. It's designed to make the task less daunting to users unfamiliar with Linux. It does not install anything onto your computer, and contains the drivers right inside of it.
Is there risk involved?
I won't lie. There is a small amount of risk using this. Then again, there is a small amount of risk with almost everything you do with your phone. There's even some risk in the HTCDev method. Doing this is a lot less scary than it sounds. Many people have used this method, and many have used the Toolkit to simplify the process. If you have questions, you may always post them inside the thread.
Is this a one-click method?
No. Not quite. It will still require you to use short commands.
Will I still have to work in a Terminal?
Yes... But don't leave yet. Most of the processes are done for you, and require entering a single letter to run a process.
Should I backup my phone before doing this?
Yes. Whenever doing something like this, you should always make backups! Also, this method will require you to flash a RUU after you are done downgrading and doing the Revolutionary S-OFF. You WILL lose all data on your phone (not SD Card) when applying the 1.13 RUU.
How do I know that my phone is bricked?
If the screen powers on and displays anything at all, it is not bricked.
I'm unlocked using the HTCDev method. Do I have to do anything different?
You will have to lock your bootloader before starting. Since you likely already have the benefit of backing up, do that before locking. Lock your device by using the HTCDev Relock feature in the Toolkit, or the command: fastboot oem lock while in the bootloader (Fastboot-USB mode) on your phone. If you are running a custom ROM, there is a chance that your phone will reboot and give you a Security Warning. You will have to apply a stock 2.08 or 2.17 RUU before proceeding. Get the 2.17 RUU from here, rename it to PG86IMG.zip (If file extensions (.zip, .doc, .mp3) are set not to show in Windows, just rename the file 'PG86IMG'.) and place it on the root (main directory) of your SD Card. Boot up your phone and run the RUU all the way through. Remember, running this RUU will erase all data on your phone (not SD-Card though). Now, continue as if you hadn't taken the HTCDev Unlock.
Please make sure to keep this thread limited to questions and comments on the live CD. For support with the Downgrade method, it's probably best to keep discussion in Unknownforce's thread. I will try my best to support the CD, but I cannot guarentee that I will be able to continue to answer questions about the CD.
