He has a shop on Taobao, but mainly sells in the QQ group.
他淘宝上有个店铺,但是基本上不在淘宝上卖东西了,主要在QQ群里交流。

Hi~

Can you use QQ or WeChat?
Now we discuss this in QQ groups and WeChat groups.
QQ group No. is 384456070.
Wechat group, you can send me a message and I replay a QR code, use Wechat scan the QR code to join.
Also, you can find him on http://bbs.38hot.net/index.php, but this old forum may have some problem with registration.

Sch and firmware I think you found is "Handheld 6.5" ,not the lasteset JOY6.5. And we have the lastest firmware of "Handheld 6.5" in QQ group.
