HTC Desire Z upgrade to ICS

Well now that I've managed to downgrade and root my HTC Desire Z, I think its time to start pushing newer roms to check how the phone takes the upgrades. this is purely for testing purposes.

The write up for downgrade and rooting can be found at the following link.

So the first step is to find a ROM thats stable enough to test. After reading up different forums I thought to stick with Andromadus Mimicry rom.

Here's the summary of the steps that I followed.

1. Download the relevant files (Rom and gaaps)

2. Move the downloaded files to the same place as the "adb" executable
*./adb push mimicry-1.5.0.zip /mnt/sdcard/
*./adb push gapps-ics-20120429-signed.zip /mnt/sdcard/

3. Make a nandroid backup for your current rom
* ./adb reboot recovery
* go to 'backup and restore' on the CWM menu
* select 'backup'

4. Clear cache and wipe all data
* from CWM screen choose 'wipe data/factory reset'
* once thats done select 'wipe cache partition'

5. Install the ROM and GAAPS
* from CWM menu select 'install zip from SD card'
* from CWM menu select 'choose zip from SD card'
* select the mimicry zip first
* follow the graphical installer steps and finish the installation (i didn't choose the wifi calling option for T-Mobile)
* once done choose gaaps zip file from CWM menu
* once both installations are done run './adb reboot recovery'
* and select 'reboot system now'
* have patience this will take some time :)

All good to go. Im going to test this Rom for few days before updating it to KitKat next.
