Redmi Note 15/ Note 15 Pro+ Instant Bootloader Unlock

If you’ve been looking into unlocking the bootloader on a Redmi Note 15/ Note 15 Pro+ from Xiaomi, you may have already realized that the standard Android unlocking steps don’t really apply here. This isn’t like unlocking a typical device where you just enable OEM unlock and run a tool. Black Shark hardware follows a different approach, and understanding that early can save you a lot of wasted time testing random guides that simply won’t work..

Why Standard Unlock Methods Don’t Work

On most xiaomi devices, you can use the Mi Unlock tool after getting account authorization. However, Redmi Note 15/ Note 15 Pro+ devices use a restricted on some regions via server-side authorization system, with the service you can skip waiting time completely, its a Instant unlock service.

This means:

Fastboot unlock commands are blocked
No public unlock permission request page
Mi Unlock tool will not detect authorization
OEM unlock toggle alone does nothing

Risk:

⚠️ Full data wipe is required
⚠️ Warranty may be void
⚠️ OTA updates may fail
⚠️ Widevine/security level can drop
⚠️ Risk of soft brick if done incorrectly

How the Instant Unlock Process Works in Reality

Instead of being handled locally on the device, the unlock permission is controlled remotely. In simple terms, the device needs to be recognized and approved before anything can happen. The process generally involves checking the device identity, verifying it through the authorization system, and activating the unlock support.
