[GUIDA][UFFICIALE] Sblocco del bootlaoder e flash ROM via fastboot [Xiaomi Mi A1]

Ciao a tutti,
quando provo a rottare il mio Xiaomi, dopo aver digitato fastroot devices mi esce questo errore:
fastboot : The term 'fastboot' is not recognized as the name of a cmdlet,
function, script file, or operable program. Check the spelling of the name, or
if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ fastboot devices
+ ~~~~~~~~
+ CategoryInfo : ObjectNotFound: (fastboot:String) [], CommandNotFo

+ FullyQualifiedErrorId : CommandNotFoundException


Suggestion [3,General]: The command fastboot was not found, but does exist in the current location. Windows PowerShell does not load commands from the current location by default. If you trust this command, instead type: ".\fastboot". See "get-help about_Command_Precedence" for more details.

Usa il prompt dei comandi (CMD) invece di powershell oppure se vuoi usare powershell metti ".\fastboot devices"

.\fastboot oem unlock
argc is 2

Quel comando è per sbloccare il bootloader, non per rootare il telefono.
Dovrebbe anche averti resettato la memoria interna.

A ok. In realtà ho ancora tutto come prima. Che guida posso seguire per rootarlo? Vorrei provare a recuperare delle foto con DiskDigger ma mi dice che per fare una scansione più complete devo rootarlo.

Alcune domande ( un pò ingenue)
Se non si ha necessità di rootare il cell. per flashare Custom Rom o mettere la Gcam serve sbloccare il bootloader (mi pare di avere capito che non serve)?
Si può flashare TWRP (senza root) con MIFlash e mantenere la possibiltà degli OTA? (mi pare di avere capito che non si mantiene l'aggiornamento via OTA e si deve fare manuale, inoltre se non si installa dopo una custom rom si ha il bootloop )
In altri termini vorrei istallare la twrp senza rootare, mantenendo la stock rom e gli Ota.
