this is the 2nd time i changed the motor in my tekin rs and the 1,2,6,7 led light up?
last time i had to re-download the v212 hotwire software and reset to default settings and it worked
this time its not working. i now have a tekin redline 8.5 motor on the tekin rs and no matter what motor setting on hotwire i do sensored or dual mode the esc gives me the same error msg? wtf???
any ideas?????

I would hook it to the hotwire and double check that it is in BL mode not BR mode. Change the setting to BL-FW then to BL-DL or back and forth to whatever your final setting is and see if it changes on the Dashboard of the Hotwire. If you see it changing then see if you still have the code. If so I bet the RS is faulty and you should send it in.

The chances of two faulty motors is low. I would also double check your sensor wire and make sure your A B C leads aren't touching anywhere.

Don't take this the wrong way, but if your soldering skills are weak, you need to check down at the board on the RS where the solder posts attach and make sure you don't have any of the motor phases bridged.

If there's absolutely nothing visible that could short out two motor phases, clean it anyway with a toothbrush and some denatured alcohol. "Nothing really there" doesn't count, anything that can make any kind of electrical connection between motor phases will cause that error code, including tire sauce, certain kinds of dirt, solder flux, etc.

If that all checks out and you still have the error code, pull the back plate off your motor and make sure the phase plates are also not touching or electrically connected in any way. Sloppy soldering can drip solder inside the motor can bridge 2 motor phases. Also take the chance to take a look at the color of the windings. They should be a fairly bright red or copper color. If they're dark red, or black, it could be the motor itself.

If everything above checks out, try disconnecting the sensor wire and see if the error code stays the same.
