hello, I finally dared to sign up. so far have read many hours here in the forum and have already mastered quite a few projects.

i have a Lime gen3 scooter from an auction and want to unlock it. I removed the controller and the battery and started the experiment.
I have all the files. in the first attempt he had no communication with the controller, the second attempt with pin 7 on GND made the STLink flash blue and it says controller is protected. I tried everything possible for an hour, unfortunately without success. where am I making the mistake? I checked the wiring and pins. everything is correct so far.

is there any other way?

I am very happy about your suggestions and solutions.

I just do not understand what did I go wrong.Thanks for any sugestions. :oops:

In case you still need help.
You have to tie pin7 of the stm to ground, to cause it reset.
You need to make a few tries for timing and hitting pin7.
You have to tie pin7 to ground while plugging in the St-Link and than release it, than you can remove read protection.
