Received ZT-180 on 28-09-2010 from www.merimobiles.com Ordered on 21-09-2010, shipped on 26-09-2010
Received with battery fully depleted.
The first thing I wanted to do was to install the latest Firmware as I had head that the stock firmware installed on all ZT-180 was quite old and rubbish.
After going through a lot of links I found that If you want to install firmware then first thing you should check is what frim ware you have.
To do this ---> From the home screen find the settings icon.
Click Settings > About Device > Build Number
Find the string starting eng.2010 and the next four characters are the build number.
I found mine to be 0830 which was not that old and thus I decided not to install the latest version. Also , it turns out that there are no current drivers for WIN 7 64 bit for flashing the ZT-180 android tablet
-----------------------------------------------------------
I have now updated to 0930. I had to use my WinXP netbook todo so
Some news. I have now updated the wifi antenna. To do this I have removed the first capacitor in the matching network and added a monopole antenna to it. Doing this I have incread the signal by 5-10db
