I desperatly need chip / hack / tuning for my 4 pro bought in Spain. It only run 20km/h at max. Is there any news regarding speedhack / chip / tuning for 4 pro?? I came in touch with an Germany seller named "Dennis" which claims he has a working chip for 4 pro, like the chips showed at youtube for older xiaomi models. He say the chip for 4 pro came on the market 5 weeks ago. He want 110 Euro for the 4 pro chip, and i want it. But i dont know if i should trust him, he could be a scammer.. Any advice?? Does anyone know if there is launched such a chip for 4 pro 5 weeks ago??

Regards

In Greece still nothing ....hope something come up soon
