some of these methods were figure out from the windows version of unlocking the amaze 4G from Binary100100 here: http://forum.xda-developers.com/show....php?t=1426377
IMPORTANT: THIS WAS TESTED ON TMOBILE AMAZE 4G (are there other versions? would it make a difference? can someone more researched answer that question?)
Before doing any of these steps, I ran system software update MULTIPLE times.
Choose Settings->About Phone->Software Updates (or HTC Software updates for earlier versions).
Repeat this until there are NO MORE software updates. This makes sure all your systems are up to date.
1- Go to the https://www.htcdev.com/ and unlock bootloader.
Follow instructions on the website, they are well documented, and easy (although it takes a few steps)
DURING THIS PROCESS YOU WILL DOWNLOAD THE MAC VERSION OF FASTBOOT (fastboot_mac)
2- create a directory in the top level of your hard drive (not the desktop, but right at '/') called android. put fastbook_mac in this directory.
Install ClockworkMod Recovery
ClockworkMod Recovery can be installed with a combination of a few steps, and a small hack.
we will use fastboot_mac to install clockworkmod recovery
3- Download the attached recovery-cwm-ruby-188.8.131.52.img (below)
make sure this is in the /android directory with fastboot_mac you created in step 2
4- Put phone in fastboot mode.
a. remove and replace battery
b. hold volume down, and then power. Hold together until bootloader starts up.
c. choose fastboot
5- install clockworkmod with fastboot.
open a terminal. then use these 3 commands. enter each one on a separate line (in order)
./fastboot-mac flash recovery recovery-cwm-ruby-184.108.40.206.img
Install ClockworkMod Superuser
7- Install ClockworkMod SuperUser from the Google Store
just download and run the app.
8- on first install you will be asked how you would like to run superuser. The install recovery method didn't work for me, and I just chose to install it (3rd button on right).
Hope this helps someone else following in my footsteps.
I also admit I'm totally doing this so I can remember it again later if I need to!
