You can simply download any full ROM package and downgrade with the official recovery. I have done it as android 10 was draining upto 50% in less...
If anyone would like to downgrade to Android 9 do let me know. I HAVE done it without using TWRP. the battery is very weird and I got around 3 hour...
Sure here it is, I shorted it - http://go.quickfever.com/pie-5t
Can you provide link for Open beta 20 Oxygen OS?
Anyone who is downloading Open Beta 20 from System Update, kindly upload it to Google Drive or androidFilehost and paste the link here.
Added Google Drive/ Open Beta 20, 5T here https://quickfever.com/download-oneplus-5t-open-beta-20/
You can't. You need Custom recovery for this task.
Use a different TWRP. This solves the issue. 100% tested.
I use GoodLife theme and Google sans font.
Sorry i should not have said that.
