Installing it on x86/x64 PC hardware will fail unless you are using a specific emulation layer or have an old ARM32 device.

A functioning Windows PC (Windows 8.1 or later) – You will run the media builder here.
At least 15GB of free disk space – The UUP files expand significantly.
USB flash drive (8GB minimum) – For the final installation media.
The UUP files for Build 15035 – Search for 15035.0.170210-1800.rs2_release_clientcombined_amd64fre (ensure you get the correct architecture: x64, x86, or ARM64).
A third-party UUP media builder script – The most reliable is "UUP dump" or the open-source "uup-converter-wimlib" script.

Build 15035 will accept generic Windows 10 product keys (like VK7JG-NPHTM-C97JM-9MPGT-3V66T for Pro) for installation. Do not use this build for production or mission-critical systems.

4. Installation Walkthrough (Lumia 950 as example)

Step 1: Unlock bootloader (requires JTAG or hacked Secure Boot – this is the hardest part). Step 2: Boot into mass storage mode using WPInternals tool. Step 3: Flash the FFU using thor2:

thor2 -mode uefiflash -ffufile "15035.ffu" -backup_data_partition

Step 4: After flashing, device reboots into Windows 10 Mobile bootloader, then loads the OS.
