It was direct from Amazon unfortunately. Toolbox is good and gets me most of the way to what I need, it's just getting Google family link on it that is missing...if u get from Amazon, u are out of luck. physical stores like BB or Target may have old stock, those MAY be rootable. head over to https://forum.xda-developers.com/t/...otloader-unlock-brainstorming.3979343/page-35 n check ur serial and lot numbers.
best guess is HD10 2019 built before Mar 2020 may be downgraded to 126.96.36.199 n rootable from there. good luck!
