[HTC Amaze 4G] aj_2423:
*****Disclaimer: As always, though there is little risk in doing this, if you turn your device into a building material (brick), blow it up, or it vanishes in thin air, I will not be responsible*****

****IF YOU HAVE AN UNBRANDED aka ASIA VERSION aka Factory Unlocked HTC AMAZE, PLEASE READ THIS ENTIRE THREAD BEFORE DOING ANYTHING TO YOUR PHONE. MAKE SURE TO READ THE FIRST & SECOND POST****

***The following is a brief description of the very common scenario that most new users with the Unbranded unit have encountered lately. Please read it now so you can hopefully avoid going through it in the future***

**SO, you got yourself an HTC AMAZE 4G that is UNBRANDED (also referred to as INTERNATIONAL VERSION, ASIA VERSION, Carrier-free, or Factory Unlocked) Congratulations! And welcome to our forum..

Now, if you haven't noticed yet, the Unbranded Amaze comes with stock Gingerbread (GB) as the Android OS. So you look and see that IceCreamSandwich (ICS) was officially released by HTC for the amaze. SO of course you go straight to settings>about phone>update, your so excited to get ICS on your new Amaze, THEN BAM!! Your phone says everything is currently up to date. But how? GUESS WHAT, THERE IS NO OFFICIAL ICS BUILD FOR THE UNBRANDED AMAZE.. Soo THEN you maybe do a little research and learn you can manually flash an ICS RUU to your phone, you just need to find the RUU for your carrier.. BUT wait, oh no, you don't have a Carrier so there is no RUU. THIS is when most people make a common MISTAKE. They decide to Unlock the bootloader an their phone, flash a Custom Recovery, and then flash a custom ICS Rom and think it will be Fine, but when they try to turn on the phone it just get's stuck on the boot logo.. Now begins the freaking out, the obsessive duplicate thread creating, such as "HELP Trying to get ICS on my unbranded Amaze" or "Flashed Custom ICS rom on my Unbranded Amaze running GB 2.3 now phone is stuck on boot logo IF YOUR PHONE IS ON GB, YOU CAN NOT FLASH A CUSTOM ICS ROM UNTIL YOU HAVE FLASHED THE ICS RUU OR FIRMWARE PACKAGE. UNFORTUNATELY, YOU CAN NOT FLASH AN ICS RUU ON AN UNBRANDED AMAZE UNTIL YOU HAVE FOLLOWED THE STEPS IN THE GUIDE BELOW!

ENJOY**

*[GUIDE] Now, i will explain step-by-step how to MANUALLY upgrade from GB to ICS on an UNBRANDED Amaze, and hopefully avoid the headache others are facing.

1.) Make sure you have required HTC drivers installed

2.) Download Hasoon's All-In-One Toolkit

3.) Unlock your bootloader through htcdev.com (hasoon's toolkit can help)

4.) Now perform S-Off. You have to be on Stock Ruu to perform S-OFF, so best to do it now while you are still on stock

5.) Once you successfully S-OFF your device, you will then need to SuperCID your device

6.) When your device is S-Off and has SuperCID, you can then download this Amaze_ICS_RUU ..Rename the RUU to PH85IMG.zip and place it on the root of your

EXTERNAL

SDcard. Once this file is on the SDcard, do a battery pull, then turn the device back on while holding down the VOLUME DOWN button. it will prompt you to install, select yes and YAY, you will now be on ICS.

7.) Take the PH85IMG of the RUU off of your SDcard, and then put this PH85IMG of HBOOT on to the SDcard. Repeat the same instructions as step 6 to flash this IMG.

8.) Congratulations, you now have stock ICS. If you would like to flash custom ICS or JB roms, continue with steps 9 & 10

9.) Finally, Use Hasoon's toolkit to, Flash 4EXT Recovery AND

10.) Then to flash supersu.zip to gain root (also done using hasoons toolkit)

OH AND ALSO, you weren't thinking about creating a new thread asking anything about this topic were you? I hope not, seeing as all these people already did. these were all found only on pages 1-6!!! I didnt even have to use the search feature...
