Hello to everyone!
I have bought ninebot E22D few days ago.
I would like to unlock the maximum speed on it. After connecting and activation it upgrades to DRV 2.6.15
I read the topic and answers. As i understand, i should to downgrade the firmware before i can change SN or change region.
I have found this link with edited firwares https://files.scooterhacking.org/firmware/e-series/DRV/
there I found that latest firmware is DRV271 - but it is higher than the latest on my scooter. That's why I thought that this firmware is for E25 or E45? Am i right?
I dosn't have android devicе - only windows laptop. So i don't want to make a mistake and flash first DRV271 from the link above and after downgrade to lower version.
Does anyone have a solution or advice on how to do it right?
You have to use an ST-Link to downgrade to DRV255, which means soldering wires to your control board. We don't have an ETA on when a wireless downgrade method might become available.

That's what happens when you use a D serial number on some of the newer software versions. Unfortunately, the only solution at the moment is to use an ST-Link.

Thanks for the answer. I would like not to solder my board and wait - maybe a new method will come. Hope it happens soon!

Same Problem . The only solutions at the moment are downgrade using ST-Link or wait for a new update of SHU App that unlock the downgrade from last Firmware version .

After an attempt to downgrade to DRV255 there is information "Flashing Failed - Reason: Data format error"

You have to use an ST-Link. There is no other solution at the moment.
