Since Poco F1 is made by Xiaomi, shouldn't it need unlocking with their not only hard-to-find, but also a half-working program which requires, and i am resorting to bullet points for emphasis:

• a cloud account with your phone number linked

• simcard of said number inserted (and i guess also mobile data active but not sure)

• turning sync of sms and contacts and find my device on, probably not very wished of if you consider where that information ends up

• a waiting period sometimes reaching almost a month

• successful operation of Xiaomi's servers which you have no influence on their operation of during said waiting period

• keeping simcard and sync features enabled during said period to allow the device to heartbeat xiaomi's servers to not reset the period

which with latest phones doesn't even seem to be planned to be working in the future, with the arrival of "HyperOS"?

i am aware that some very old devices have a 0 waiting period, but not sure with this device?

with personal experience, if you buy them refurbished (in my case that was a redmi note 10 pro) unlocking the bootloader just doesn't seem to even be possible (the motherboard was likely replaced, but not registered on xiaomis end). i mean, personal anecdotal experience, but shows the fragility and risk of the systen they set up, so that it just doesn't seem to ve worth buying them anymore..
