### Disclaimer ###
I am not responsible for damages of any kind. Follow at your own risk!

### Warning ###
- Sync your clouds apps and backup all local data. It will be erased during the process!
- READ EVERYTHING at least once carefully before approching it yourself!

### (My) Starting point ###
I installed OOS10 with the MSM OOS tool, then updated to OOS11 11.0.0.2 ( Bootloader locked and not rootet). At this point i had problems with Widevine or anything. You may want't to backup your persistent partition with the MSM OOS tool (driver) since users reported that it was corrupted randomly while using the phone.

### Windows ###
You may need to install ADB driver manually... Download latest usb driver windows and install like that (I need that when my device was in the bootloader)

### OS Download ###
Download your current os with the Oxygen Updater using the Full update option. Store it on your computer.

### OEM Unlock ###
(1) Activate Dev mode in Android, activate USB Debugging OEM Unlock in Dev settings
(2) Using the platform tools send adb devices and accept ADB on your phone. Then send adb reboot bootloader
(3) Send fastboot oem unlock and confirm on your device
(4) Set it up but don't connect to any network yet

### Wallpaper and stuffrepair after unlock ###
(1) Make a local update with firmware from ### OS Download ###
(2) (It's almost not noticeable but i want't it to be perfect) Tap long onto the sttings app -> select edit -> Press on the icon ->Choose the Oxygen settings icon ->OK

### Root ###
