After evaluating the available information and community consensus, a clear conclusion emerges:
As of 2026, there is no one-click installer, no TWRP flashable ZIP file for the general public to download and use. The developer Balika011 has mentioned a possible software-based secure boot exploit, but as of the latest information, it remains unfinished and not available.
~30–60 minutes if you have all files ready.
Now it's time to download and install your custom ROM.
Because the bootloader cannot be unlocked, you cannot flash a traditional custom recovery (like TWRP) or a standard custom ROM (like LineageOS) directly to the device’s internal storage. So, can you get a custom ROM on the Priv?
The BlackBerry Priv remains a landmark device in smartphone history. Released in 2015, it boldly combined the security of BlackBerry’s Android software with a gorgeous, slide-out physical QWERTY keyboard.
