@bradster3 also, its my old bms is on a 2.0.8 revision, new one is a 2.0.7 revision so that might be a issue.

@mirhannes check ebay. Ive seen a few here in the us for 180 bucks witch isnt that harsh. They pop up frequently and i just bought one for 120 from a seller.

Long story short i fried my old bms in my xr due too rain. Was able to pull the hex from it when it was on 4209 but dropped the ball and accidently updated the board while diag. Got a new bms from a pint on a low revision and sent the hex file i managed to pull off the old bms and send it too the new bms no issues. However, when i hooked it up i get nothing. Plugging in the charger waskes up the controller not the bms. The bms is tested good from the seller. Im guessing my hex got currupt somewhere down the line and i need to test a good working hex to make sure its a whole other issue. Keep in mind the old bms would force the board on and would not turn off till i unplugged it. Any help would be appriciated.

@lemur not to bring a sub back from the dead, but you know where i can find the xr bms files. I had a old xr bns i pulled the hex from with no lock but it got messed up somewhere. I have a brand new pint bms and when i try to push the hex the ow does nothing, does not turn on, no light, nothing. Im guessing the hex is bad because the old error was the board wouldnt turn off....guess i found the root issue. If you could point me in the right direction i would be greatful since i cant ride if no power lol.
