Sure, last adb and fastboot 1.4. oos 12.1 dn2103_11_c.10
Also my computer does not have 2.0 ports it has 4 usb 3.2 and 1 thunderbolt 4
OOS 12.1 dn2103_11_c.10 lacks fastbootd as per all post I read, neither BROM mode to use mtk client.
So once on this version you cannot do nothing with your phone. Just stock.
You can downgrade to A11 or A12_C01, unlock and then update. I didn't myself. Stuck with A11 for now.
Please check the forum post here and will find how to downgrade and the problems with the C10 update.
adb and fastboot 1.4 is not the problem, but I updated my installation with latest executables from Google platform tools to stay up to date.
The USB 3.0 support seems that is not problem anymore. Was few years ago.
Hope helped. Luck.
