OnePlus Nord Device Overview:
OnePlus Nord is powered by the Snapdragon 765G chipset which is 5G enabled. The phone is coupled with 6-12 GB of RAM and offers storage options of 64/128/256 GB. OnePlus Nord does not have a dedicated microSD card slot. The phone sports a 6.44-inch display with 1080 x 2400 pixels, a 20:9 ratio, and 408 PPI. The device has the protection of Corning Gorilla Glass 5 and features a 90Hz refresh rate with
HDR10+ display.
It comes with Android 10 OxygenOS 10 out of the box and with a remarkable OnePlus software update policy, this phone is eligible to receive Android 11, 12, and even 13 updates, whenever that comes out. FYI, OnePlus offers 3 major firmware updates along with 3 years of security updates, which is the best in class alongside Google Pixel.

I tried to perform this downgrade on my new Nord n10 5g but the System Update setting for local upgrades is telling me to place the update file in the root of storage. So I had it there, but the system would not find it automatically and there was no option to browse and select. Should I be renaming the file to something else, that will be recognizable as a system update? Thanks for any help.
