+
+Erase with an stlink and flash this [uf2boot bootloader](https://github.com/daskygit/uf2-prime-plus), this is a a one way procedure voiding any warranty so be sure you don't want to use the original manufacturers firmware.
+
+you may need to remove write protection to flash, e.g. with openocd in linux
+
+```sh
+openocd -f interface/stlink.cfg -f target/stm32f1x.cfg -c "init; reset halt; stm32f1x unlock 0; flash protect 0 0 last off; reset halt; exit"
+
+```
+
+and write the new bootloader
+
+```sh
+
+openocd -f interface/stlink.cfg -f target/stm32f1x.cfg -c "program build/PRIME_PLUS/uf2boot.bin  verify reset exit 0x8000000"
+
+```
+
+* Keyboard Maintainer: [Dasky](https://github.com/daskygit)
+* Hardware Supported: SteelSeries Prime
+* Hardware Availability: https://steelseries.com/gaming-mice/prime
+
+Make example for this keyboard (after setting up your build environment):
+
+    make steelseries/prime:default
+
+Flashing example for this keyboard:
+
+    make steelseries/prime:default:flash
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
+
+## Bootloader
+
+Enter the bootloader in 2 ways:
+
+* **Bootmagic reset**: Hold down left mouse button and plug in.
+* **Bootloader entry**: Hold the underneath button while plugging in.
