oneplus 9 pro authorised OxygenOS 13 gone
I downgraded my oneplus 9 pro to OOIS 12. After downgraded my device model was changed also some authorised app was gone like phone dailer,message. So I wanna know that How can I get back T Mobile O...
might opt to get your info in the same place that walked you through downgrading back to 12. almost safe to say when you downgraded you downloaded a different variant of 12 that TMO doesnt use..if it did you wouldnt be having issues with the dialer etc.
