(TUT) Unlocking the Ninebot E-series (E22, E25, E45) to 28 km/h (30 on E45)

[ogor]

My e45 was locked at 13mph from upgrading to the newest firmware using the ninebot app (bad idea) and changing the region with another app.

I was able to downgrade by using the st link and the scooterhacking windows app(follow the stlink instructions), then used the scooterhacking android app to upgrade to drv 5.5

Hi, hi, could you share a link to the description of how to downgrade the DRV using ST-Link?

Was the st-link procedure like this: https://youtu.be/Kba7yK9NV6c ?

And can someone verify/clear up that when people say on this thread that we need to st-link the control board, does the control board mean the one that is with the display etc. (easiyish access) or the one that is down with the battery (lower, a bit more difficult access)?

Does this work for the e2?

With my Segway E22 it did not work, I tried multiple times, when I try to change the SN what the scooter does is it just beeps and nothing is changed

Hello, I Flashed my Ninebot e22e with the Xiaoflasher app and I opened the Segway application by mistake, and now it is region locked and does not allow me to change the region from XiaoFlasher, so I decided to try SHU and when trying to download SHFW it gives me an error of "Flashing Faile, Update Failed! Reason: Data firmat error. power cycling your phone and vehicle might help. I have already tried restarting the scooter several times and still with the same problem. I cannot download SHFW or change the region of the scooter or use the tools in the Flash tab. How can I remove this blockage and how do I solve the SHFW installation problem?
The scooter also changed its SN for one of the e45 and it won't let me change it for the original, help

I need urgent help, I have been having this problem for several weeks

Thank you
