Serial number HiB PQ65G45160902040 I attempted to upgrade the BIOS in a CWI526 HiBook Pro using the file at this location:- [[HiBook] [Official Version] Chuwi HiBook Bios + Android + Windows download](https://forum.chuwi.com/t/hibook-official-version-chuwi-hibook-bios-android-windows-download/963) but now the screen does turn on nothing happens, it does not even attempt to boot. Ironically the document states the following:- **Flash BIOS** （If it’s reinstall system, you can not flash bios，flashing the wrong bios may result in no display,Please be cautious.） What exactly do you mean by “reinstall system” and is there now a way to recover from this? ---

In Chuwi support. if the device doesn’t start, there’s nothing you can do. To find out about the BIOS you have to search on Google ---
