I recently upgraded my old HTC Hero from CM6 to 7 . The install process was pretty painless largely due to the fact I had the bulk of the work done from when I installed CM6 previously.
The upgrade and install process
I used rom manager to download and flash the rom and google tools but not before backing up my applications and data. I used the well known titanium backup for this . Once this was completed I chose to wipe the dalvik cache and system data and proceeded to install the rom via rom manager.
The install process completed fairly quickly and within no time I was back up and running . I had previously read a few reports of the rom behaving sluggishly and some people having problems, so I was anxious to ensure all the essentials worked.
Wifi , camera , gps , audio and the rest worked fine with no problems. I did notice the rom feeling a little sluggish though. To remedy this I went into the settings and overclocked the processor the 710Mhz . I tried to push it higher but it kept shutting down . Also another thing I did was to install launcher pro as the default dock instead of ADW that comes with the rom by default. I found these tweaks to greatly improve the speed and responsiveness of the rom.
So how does it compare to CM6 ?
Overall the rom seems to be more responsive , I had applied the same tweaks to CM 6 also so I’m not sure how much of a difference there really is in terms of speed or whether it is mainly the placebo effect.
In the previous version I had to install setCpu to overclock the processor while this rom had the option built into the settings. This made it very convenient and saves space too.
The UI looks a lot sleeker this time around and allows for greater theming options. Some examples are the status bar , the dialer , the keyboard.
CM7 also has the ability to take screenshots by default which saves me having to connect it to ADB via USB to take them.
Overall I am very pleased with the performance and quality of the rom and I would like to take this time to thank the cyanogen mod community for the hard work they put into their releases and for keeping the older models alive.
