Only china variant is out currently (31st jan) (unlockable) so obviously no one can tell you about global variant
Edit:
Finger print reader becomes disabled after unlock
You will need a cheap plastic device from ebay to recalibrate the fingerprint reader and it will work again after that (or relocking)
So you originally stated: "Redmagic phones have always been bootloader unlockable." which is great and what I thought but this is what I got every time I rephrased/reworded my question to thier support team:
"Dear Valued RedMagic Customer,
Thank you for contacting us.
We are sorry to inform you that we do not have any device with an unlocked bootloader.
Once we hear back from you, we will certainly help you with your query as soon as possible.
Best Regards!"
All the different ways I attempted to get an answer:
"I understand that the bootloaders always shipped locked. Does any variant/region of the Red Magic 8 Pro have the capability of being bootloader unlocked by the end user? via adb/fasboot commands EX: "fastboot oem unlock"."
"Are any of the RedMagic 8 Pro series bootloader unlockable? And if so, what model and regions?"
"The Red Magic 7 can be OEM unlocked (bootloader unlocked). Can I please be connected with a tech at this point?"
The last one was an attempt to get away from customer service but still got the generic response.
