[LG Optimus Me P350] JimvanDam:
My LG p350 did not turn on and the home, back, and the other two lights blinked for a while. Now I followed a tutorial on how to install a new firmware, but, very unexpected, KDZ_FW_UPD_EN.exe gave me an error:

And now it doesn't do ANYTHING anymore, not even emergency mode.

I have no idea what to now from here, so help is very much appreciated.

(I also saw a guy on youtube fixing this with some special device (h t t p s : / / w w w . y o u t u b e . c o m / watch?v=POZGmcMhi7o), but I don't have that...)
