Hi there!
First time, I've made everything the same way as
duxxyuk and other folks and FW update procedure went just fine. I've used
chupito57's FW. But I found that Ukrainian language in this FW is totally useless (the problem with encoding - all characters were like abracadabra).
So I decided to look for another FW. On the 4PDA forum (Russian) I've finally found the one I was looking for. And started the upgrade procedure:
1. Loaded FW into Upgrade tool (RK28Upgrade v1.27)
2. Then pressed "Switch"
3. After a while pressed "Upgrade"
Upgrade started but in a few seconds I've received error message.
Now, the problem is that every time I plug-in the device, Windows (Windows 7, Ultimate, 64 bit) recognize it as "Unknown Device" under USB Controller tree. I was disconnecting all the additional USB equipment (except keyboard and mouse of course
), changing the USB cables without any luck...
I will appreciate any suggestions from your side...
Thank you in advance!
