Need Help! Generation 3 ST-Link V2

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.

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.
