In the previous post (New Mele A1000/A2000 ICS Android 4.0.4 firmware released) I announced a new firmware.
Seems that it fails to be flashed with PhoenixCard 3.0.3 on Windows 7 (thanks to JP for pointing it out, see the old post comments)
On mele.cn forum: http://bbs.mele.cn/showtopic.aspx?topicid=751&page=end someone has the same issue.
I never noticed this since I flashed from a Windows XP virtual machine.
The solution is to upgrade to PhoenixCard 3.0.6 on Windows 7, or run the tool on Windows XP.
I made a video from a Mele A2000 flash failure process. I got that when I was tweaking my firmware (missing DISKFS file):
Mele A1000/A2000 flash failure
Flash success sequence, for reference: Mele A1000/A2000 flash success.
