Wojciech Plocharski Posted May 19, 2017 Share Posted May 19, 2017 my mini pro run on 1.2.2 and i feel like i might fall when reaching higher speed as the knees are almost out of the steering. is that due to 1.2.2? I dont have that problem with my xiaomi mini but the steering is obviously different. look at the video below. When I want to bend my knee its almost impossible. it doest matter how I will ajust the knee bar. It force me to stand still which I hate and feel unsecure.

I didn't ride that long on 1.2.2 but it is described by others as an overkill safe firmware (as in trying to slow you down and restricting max speed). You could try other fw versions. I will publish a newer 9BDgrader package soon that suppose to work on both mini/Pro and 9b1. Link to comment Share on other sites More sharing options...
Ozpeter Posted May 19, 2017 Share Posted May 19, 2017 Try leaning forward at the waist more, so your upper body weight is adding to the forward tilt. Link to comment Share on other sites More sharing options...

Do not upgrade to 1.4.0 yet if you can wait. There is no easy way to downgrade from 1.3.1 and 1.4.0 (only jtag method). I'll try to update the downgrade guide this weekend. The new 9BDgrader makes it easy to change firmware (anything between v1.1.7 - 1.2.8) Link to comment Share on other sites More sharing options...
Vik's Posted May 20, 2017 Share Posted May 20, 2017 I've just updated the "downgrade package" and made some adjustments to the instructions here: @Wojciech Plocharski Now, you can try some of the earlier firmware versions like i.e. v1.1.7 to see if you like them better.

Vik's Posted May 29, 2017 Share Posted May 29, 2017 @zugu, JTAG programmer is required to be tapped/soldered to the controller board in order to downgrade v1.3.1/1.4.x to lower versions. That way firmware can be written right to the memory without restrictions. Link to comment Share on other sites More sharing options...
