1. download and install new software.
2. run wellon software and exit wellon software.
3. run c:\weilei\wellon\wellon_reset.exe.
  if display "sys update ok!" ,the programmer reset OK.

WELLON VP-990 Reply  
Hi, my programmer stops working vp-990. It began with the fact that he tried to program with any chip gave an error - programmer trouble! ID: 01D414FFFFFFFFFF. But then it could still read without errors chip. Then he stopped reading them as well. Of instructions read that it is necessary to update the firmware shorting jumper. I did so.

EMP-290..I have two questions. Reply  
I recently purchased an EMP-290 from Needhams Eletronics and weilei.com is listed on the instruction booklet.

I have two issues:

1 - How do I get it out of "demo mode"

2 - Should it have an ac adapter plug? I use the USB cord and I assume it is getting power because the green G/E light is illuminated.

1.program mode:button "config",choose "hard copy(verify)" and "used(page=2112)".then read one and program the other.
auto prg choose "earse"and "program" on the right side.
2.if fail,you may choose "hard copy(no verify)" then have a try.
3.if it is still not working,maybe the bad blocks area are used for value datas,this you have to use another one.
