Question New Device Setup Questions

[Energy3759]

Waiting for Pad 5 to arrive, in meantime was looking around and had few questions.
From what the seller posting said, it is china version with bootloader unlocked to flash global rom.

1. Since you need to link a Mi account to the device to unlock the bootloader, is there a way to unlink the account the seller used to flash the global rom without access to the account they used? This is just to remove the seller completely from device. (Maybe since it's already unlocked it's not needed? Idk I'm new to most of this)
2. Even if it's a minuscule chance of seller installing some malicious programs, is a reset through device settings enough to return it to factory/stock or is it better to re-flash global/another AOSP rom.

Thanks in advance.

Received the tablet, will answer my own questions

1. There was no MI account already logged in like I had thought and someone on reddit mentioned it as well in the comments. But like the store page mentioned, bootloader was already unlocked so I still think seller account was used SOMEWHERE. I think only way to fully check would be to re-lock bootloader (using china rom) then go through the unlocking process using your own account. I'm not that paranoid to do that though.
2. I did try resetting to factory through the settings app, no asking for password of any sort appeared liked I thought might appear (iCloud lock). In the end, I ended up flashing the latest version of the global rom anyways instead of doing the OTA update. It came with V13.0.4.0 RKXMIXM global firmware.

Now I'm trying out MIUI to see if I like it enough or I might flash ArrowOS/any of the other AOSP roms that support this tablet.
