Hi guys, I'm on beta 3 what is best way to get the official 9.0 software? I've tried through oxygen updater but local updater says the firware is lower then what I have and won't download the zip.
I even tried to rollback to Oreo but facing the same issue, Oreo firmware version is lower than my current, also wont download..
Hope the experts here can give sime advice as how can i resolve this issue.
Many thanks in advance
If you're like me without twrp, and do not want to go the twrp route, you can follow the following steps to update to stable Pie.
- Backup using Oneplus Switch and transfer the backup (located in \opbackup) to PC
- Download the downgrade package from here
- Settings > System > System Updates > Local upgrade to flash the downgrade package. Data will be wiped..
- After finished the initial setup, install oxygen updater and use it to download and update to stable Pie, or download the stable Pie from here.
- [optional] perform a factory reset after successfully update to stable Pie.
- After the initial setup, transfer the backup from the very first step to the phone (under \Backup, yes it is different from previous) and use Oneplus Switch to restore.
NOTE:
1. You may want to exclude WhatsApp (including the images and videos folder) from the Oneplus Switch backup, the restoring is slow for the media folder. You can download the whatsapp from play store and restore the backup from Google drive later, it is so much faster. Of course you've to be sure you've turned on Google drive backup for Whatsapp.
2. You do not need Oneplus Switch backup if you've turned on Google backup for your account.
