[HTC EVO 3D] closeone:
Hello everyone. This is a breakoff from Unknownforce's HBOOT 1.50 to 1.40 downgrade thread. I created a Live CD to help make the downgrade process a bit easier.

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)

PREVIOUS STABLE VERSION: (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)

The HBOOT Downgrade Toolkit Live CD is a bootable version of Linux (don't worry! :) ) that simplifies a lot of the process of Downgrading your HBOOT from 1.5 to 1.4.

If ClockworkMod or the Revolutionary Team wants me to remove their software (ClockworkMod Recovery and Revolutionary, respectively) from the toolkit, I will comply with that request.
