Please note, this is a TEST ROM and may not work.

I do not have a G4 version Wizard to test on, so some brave soul with the hardware in question is going to have to give it a try. Be aware, while I have double checked everything and this should work, FLASHING THIS ROM MAY BRICK YOUR DEVICE.

Once this is confirmed working on a G4 version Wizard, I'll update this post.

The contents of this ROM are functionally the same as the standard Mr. Clean ROM. For more information on Mr. Clean please read the original Mr. Clean thread:

Mr. Clean AKU 2.3 ROM v2.24.0001a for HTC Wizard (G4 version)

-------------------------------------------------------------

The ROM of choice for tinkerers and hobbyists is back, and this time the big baldy is ready to take on the G4 variant of the HTC Wizard. Because this ROM is designed specifically for Wizard units with the G4 flash chip it WILL NOT WORK on the original Wizard. If you have an original Wizard, you must use the 2.24a version of Mr. Clean.

---------------

WHAT DO I NEED?

---------------

-A CID Unlocked HTC Wizard with a G4 Flash Chip

-Windows PC with a USB port

-ActiveSync 4.0 or higher installed

-MrClean_RUU_WIZARD_2240001a_AKU23_WWE.zip

HOW CAN I TELL IF I HAVE A G3 or G4 VERSION FLASH CHIP?

-------------------------------------------------------

There is an easy way to tell which version flash chip you have in your Wizard.

Simply look at your boot screen and check the IPL/SPL version.

2.xx = G3 Flash Chip

2.xx.0001 = G4 Flash Chip

WHAT DOES CID UNLOCKING MEAN?

-----------------------------

A CID lock normally prevents you from using any ROM aside from an official ROM provided by your carrier/OEM. Trying to upgrade a CID locked device with an unofficial ROM can damage your Wizard. DO NOT try to upgrade your Wizard if you have not CID unlocked it.

If you wish to search for a free solution, please check the forums on http://xda-developers.com. Be aware however, that free solutions are only available for certain ROM versions. As of this writing there are no known free solutions for the G4 series Wizard, but this may change in the future.

A viable alternative to waiting for a free solution is to visit http://imei-check.co.uk. This company charges 20 British Pounds (approx 40 US Dollars) to perform a SIM and CID unlock on your Wizard. It claims to handle all versions of the Wizard hardware, so if you have a G4 version, this may be your only option. It is generally accepted as the place to go for SIM and CID unlocks.

HOW DO I FLASH THE Mr. Clean ROM?

---------------------------------

1) Unzip MrClean_RUU_WIZARD_2240001a_AKU23_WWE.zip to a folder on your hard drive.

2) Make sure your Wizard has at least a 50 percent charge on the battery.

3) Connect your Wizard to the PC via the USB cable.

4) Run the program ROMUpdateUtility_Wizard_NoID.exe in the ROM folder.

5) Follow the prompts to update your Wizard.

6) When you get to the UPDATE screen the version listed should be 2.24.0001a_MRC. If not STOP NOW. You have the wrong ROM.

7) Once you start the upgrade, your Wizard will reset to a rainbow colored screen. This is normal.

8) The Wizard then switches to a blank screen with a progress bar. It may pause for a few minutes at 98%. This is normal.

9) Once the update has completed, the Wizard will reset and present you with the initial configuration.

10) Calibrate the touch screen and let the customization option complete.

11) After the customization completes, the Wizard will reboot a final time and the upgrade is finished.
