@blankman Dowgrading with stlink requires that you have extracted your bootloader and settings for the correct serial number, mileage.
If you use someone else's bootloader and settings then you need a special program to change the serial number, mileage.
After stlink, then you can Rewheel with encrpted file 5040, if you don't have the 5040 file then no point going any further.
What was your goal try to get into factory mode?

I just received the Ennoid MK8 with the BT module.
I rewired a stock XR/Plus power switch as the MK8 needs a momentary NC switch, the stock XR switch is wired NO, but has a NC terminal on the switch, the led lights up fine on 5v, normal XR/Plus led is fed by 12v.
This switch makes using the stock XR controller box a lot easier.
The 6.05 firmware is already loaded in out of the box.
I will be running 24s1p Molicel 45b for now and a Stokedstock bms

@loaffette They're bright but doesn't thow a beam very far, I still use a helmet mounted bicycle headlight when I ride at night.

@loaffette I use to carry a solar charger, a 36v hoverboard battery, charging adapters, in a camera bag for group rides.
The solar charger converts the 36v to any higher voltage up to 90 v all programable with memory for different boards.
I've gone to 24s, so I can't use this anymore.

@loaffette The front light bar is just a constant headlight, not rgb, the rear is rgb and uses a Adruino Nano for different light patterns.
The front led strips canme from a dollar store much like the ones on Amazon, each pair of light strips run on 3v and are quite bright.
So you get 2 headlight strips and four cheap AAA cells from one wall switch light.

@kusosan I used the stock motor but I cut off the 9 pin Molex and used bullet connectors.
The stock XR controller box was used with a adapter for a 20mm gland, also a custom wiring harness was made. The picture shows block off plates, but on a Ubox build.
The Thor is mounted on a aluminum plate and bolted to the controller top lid.

Got the model 3 suspension vesc build parts back from the painter and mocked up with a new Ohlins shock, Pint hub with a Burris 11x5.5x6 tire.
I have 24 new p45b cells and a SS bms, just trying to decide on Thor 400 or MK8.

@lia Amazing work!

@lia You can also do software "posi" with FFM if your GT has not been updated.
Just need the Gt encrypted ota file.

I went backwards with my Gt/Ubox 100 build..
I switched out the SF motor back to the Hypercore motor although the GT motor now has a 6 inch rotor, 14 bolt end cover with an actual oil seal. Special axle blocks were made to center the wheel.
This is not my main ride and the extra 5 lbs of the SF is not worth the torque gain. I'll save the SF motor for another build.
The Ubox 100 has been updated to 6.05 "no limits" firmware and refloat.
The external yellow XT90 connector is a quick disconnect so the battery is not connected in storage to avoid parasitic draw.

@lemur I've since updated the Ubox lite firmware to 6.05 "no limits" which allowed the Ubox Lite to have an higher maximum input voltage from the hard coded 95v to a higher value, in my case with 22s at 103v.
Hopefully that will avoid the regen voltage spikes that will ND with the 95v input.
The best feature with 6.05 firmware is the hill holding setting that matches a OW board, the vesc board is no longer rolling away on a slight incline.

I survived the test ride on my fresh vesc build.
New Ubox Lite, 22s1p 42 A cells , Maxkgo 30s bms and out of percaution I only charged to 90 volts instead of 92.4 volts and kept my speed to 16 mph for now.
I had a warning on Float control about maxium motor voltage being too low but I couldn't change it as I believe that 95 v max is hard coded in the firmware, I not sure if a "no limits" is available for the Ubox Lite.
I had a strange buzzing and harmonics on rocking back and forth on Refloat but smooth on Float, I have to check into that.
This build was against all advice, but if you don't try, you will never know.

@weno66 Picture posted in one of your requests.

@weno66 Here you go.

@weno66 I had a diagram somewhere, I'll try to find it.

@lia Thank you!

Re: Building a updated suspension board
I fabricated a few more pieces for my third suspension build, the controller box I may use is a printed one with a Ubox 100 in it , but things change as the build comes along and the rails are longer than stock to fit a larger tire than the Pint size. The swing arm pivot is stainless steel and self lubricatig delrin bushings.
I'm presently looking for an high end bicycle shock, even better than the Mazocchi air bomber, as I believe a top tier shock is the secret for any suspension, be it a car, motorcycle, bicycle or even a one wheeled balance vehicle.
Pictures of my 2 completed and partial suspension builds. Top one is XR controller based, middle is Thor with 20s2p battery.

@weno66 When you say m2t mosfets, did you mean m8t mosfets?
When you get high and low cell voltages on adjacent cell groups usually it's a m8t mosfet.
There are 8 mosfets controlling 15 cell groups, but #1 m8t mosfet controls only one cell group.
Best bet is to get the bms repaired at Atlowshop or source a good working bms.

Watch Floatwheel's video before it gets taken down.

@lia I'm not sure what the op did, something reversed or wired wrong.
