Hi to all
A customer called to restore kia sportage 2021 u.s.a , he went to another place to do mileage correction and as per cutomer the guy was using small black tablet connected to obd2 port , i figured out its that chinese obdstar , after finishing the job his cluster converted to km instead of miles, 4wd light on, speed pointer little up , the guy disconnect and re-connect battery but nothing changed, also the adjustment not correct , customer want to restore the cluster and do mileage correction properly.
No backup file there as well.
Would anyone suggest from where to start bcz i think the data is corrupted.
Attached cluster before and after modification
Thanks in advance
