420 no zkt mod gone wrong?

[kegger316]

I've done 4 420 no zkt mods sucessfully, but I've got one now that keeps giving me a black screen and saying, "recovery mode. downloading software".
I've reflashed it several times and keep getting the same message. Any Ideas? Thanks.

Reflash it again, that's what it needs.......

Seems like some 420s are more sensitive to static and interference than others, shorten you jtag leads and keep it away from the power supply section as best you can......

I had 1 receiver that did that b4 i did the mod on it, a Chinese guy showed me how to fix it, he unplugged it, then replugged and went to channel lists and selected all channels. After a few minutes the receiver worked fine, i guess it did download the software.

I mananaged to shorten the wires a couple inches, reflashed it again. Wouldn't even power up. I tried it one more time, shut off everything around me,including soldering iron, and it worked! Thanks for the help guys.
