Where to find 4212 xr hex files for the bms
-
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.

@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.

@bradster3 I also have 4206 and Pint hex.
If you're running a 4212 controller, you may need an "Owie" chip between the bms and controller.![IMG_1561[1].JPG](/assets/uploads/files/1793889230248-img_1561-1-resized.jpg)
