Xiaomi PRO1 with V.3 controller (DRV2.2.4) won.t flash CFW

Postby tzepesch Mon Nov 28, 2022 6:47 am

Hello

A week ago I managed to burn my original controller of PRO1 and it was beyond repair. The MOSFETS are still burning.
So, I purchased a PRO2 controller, V3, reinforced that came with DRV 2.2.4.

I also upgraded the new controller with IRFB4110 MOSFETS, 1000uF 100V and 33uF 100V capacitors. Ofcorse with new thermal grease applied also on case. All good, it works by default with standard speed settings. 15/20/25 kmph.

But, I can not flash custom CFW with downG app.
I made DRV 1.5.5 CFW and also DRV 2.2.3 and DRV 2.2.4 but it can not be flashed.
with DRV1.5.5 down G won.t load the BIN.file and with DRV 2.2.3/4 it reports that i have PRO scooter and the soft is for PRO2 and could be unstable, starts to flash but immediately gives error.

My BLE is 1.2.2. Also tried to update BLE to 1.3.2. No result. Can not flash BLE.

Tried to change the serial Nr. of new controller to my original S/N. It doesn.t want to save the S/N.

All I want is to rise the SPORT speed to 35kph, DRIVE speed to 25 and ECO to 15, remove KERS and some minor tweaks.


Please help
Thank you
Joe
