These chinese devices are awesome for their price! I got a chinese Jiayu phone that works nicely. but uh too bad about your sour egg. Best option - return it for full refund or replacement. Other options:
1. contact JXD
Voice phone: +86 755 8397 3170
2. if the touch screen or physical controls work, then do a 'factory reset
' under System Settings and power off and power on. (google it...)
3. if there is physical volume button, then when power is OFF, hold volume UP and power on. or try to hold volume DOWN and power on. hopefully
you get a screen like this
. (taken from this blog
.) Another way is to hold either volume button and then connect USB cable (still holding volume button). You got golden profit now.
That is recovery mode. You can do a data wipe in there and install the latest firmware from JXD. Choose the right firmware FILE
for your model. (google it...)
4. can you remove the battery? if so, remove the battery, disconnect all cables, press power button for 10 seconds, let go of power button, insert battery, and power on
5. you can google and search inside this xda site. "jxd 7800 hardware" or "jxd 7800 touch fix" or something like that. I found "dingoonity" forums
good luck & cheers with a beer mate.
*EDIT* -- Here is a youtube video of my JXD device playing an included game "Monster Shooter - Lost Levels" in its stock rom Unfortunately, the touch screen sometimes stops responding to physical touches (my finger). http://www.youtube.com/watch?v=Ju44OWs6G2I
