How to distinguish the hardware? please press menu , and if you can see the words in Setting: "Hardware version No.:XXXXX " then the device is made with latest hardware, it has the latest firmware, and now it doesn't need to upgrade.
If you can not see the words in Setting: "Hardware version No.:XXXXX ", then it is made with old hardware, and it can be upgraded with firmware 2.0.2, and if you confirm this, the firmware for the device with old hardware is attached.
By the way, the firmware 2.0.2 only fixes device with old hardware. The device with new hardware can not use this firmware to upgrade.

!!! IF YOUR 2C32T IS BRICKED, READ THIS !!!
Just remove the back cover, unplug the battery and plug it back while holding the POWER and MENU button. You'll be back the firmware upgrade mode.
