How to flash back to OS11 on T-Mobile OnePlus 9 Pro (or any OP phone).
I had updated to OS12 on my OP9 Pro and I hated it. There are now too manyuseless features, not to mention a few of my most used features disappeared (such as the seconds on my clock in the notification bar, and the quick features by long pressing HOME, RECENTS, & BACK buttons.) So I used the MSM Download Toolkit to flash back to OS11, and I am going to use 11 until T-Mo releases 13. Here is the complete list of OP devices and their respective MSM Download Toolkit(s) associated with them. *Remember to always use the toolkit for YOURdevice model -for they are not interchangeable. You will get a failed result EVERY TIME.* This also works for BRICKED OnePlus devices. https://onepluscommunityserver.com/list/Unbrick_Tools/ For thespecific T-Mo OP9 Pro device, I have the ZIP file available to download along with step-by-step instructions on how to Flash Back to Android 11 on OP9 Pro - inside of my Google Drive folder : https://drive.google.com/drive/folders/1PbVwsUqW8Zh1sJLgl4Uf-YMkzvr8PJt8?usp=sharing1.7KViews1like3ComentariosRe: Is it possible to revert Android to the previous version? Android 12 is a disaster on the N200.

Aside from having to provide approval to get almost every function to, well, function, some things are simply broken. Example 1: Press the square button after swiping up and the 'Close all' button does nothing. If I have three apps open, they have to be individually swiped up to close them. One. At. A. Time. Android makes the right-most app full screen again and displays a meaningless message about my phone being "in optimal condition" if I touch the 'Close all' button. Example 2: Responding to text messages is hit or miss. I often find that the keyboard will *never* appear so I'm unable to type a reply. Example 3: Before the upgrade I was able to change the volume of a Bluetooth speaker using the controls on the speaker itself. Now I *must* change the volume using the phone. How can I un-upgrade? T-Mobile's version of Android 12 is not ready for release. https://community.t-mobile.com/android-9/how-to-flash-back-to-os11-on-t-mobile-oneplus-9-pro-or-any-op-phone-45584?postid=170119#post1701199Visto1like0Comentarios
