Thanks for your input 1FastBrick!
Unfortunately i did swap the usb cable no result, obd11 cable no result, different usb port on my laptop no result, loaded efilive on different laptop no result, attempted no update boot block and firmware no sucess...
Reading though all related stuff, i came to realize that the Flashscan should never be powered from two different cable to the vehicule at any moment. When i bought my flashscan, i assume i read that orange notice inside the box saying never use an inverter to power your laptop, which is probably the reason why i went and bought one of those 12 volt laptop chargers thinking it was all right, but it was NOT! Still, its been working just fine for six years but suddenly came to a stop...
So my advice to everyone on this forum: DO NOT EVER USE A 12 VOLT LAPTOP CHARGER WHILE YOUR FLASHSCAN IS CONNECTED TO THE VEHICLE! At any time you do so you're playing with your luck.
I sent my Flashscan to SoCal Diesel for repair 5 weeks ago, still waiting for an estimate...
