3. Check that your keyboard is switched to the right OS system. Ex. Switch the keyboard to Windows if you are using a Windows device.

4. Make sure your keyboard is connected to the PC with the cable that came with the box only. If you are using a third party cable, please make sure the cable can pass data as some cables can only be used for charging.

5. Make sure that you use only Keychron keyboard to connect with the PC, otherwise, it might flash the firmware of your other keyboards. If you have multiple Keychron keyboards, please flash the firmware one by one, do not plug all the keyboards to the computer all together.

6. Now start running the exe file for Windows or the app file for the Mac. 

7. After flashing the new firmware, hold Fn + Z + J together for 5 seconds to do the factory reset. You are now good to go.

What's new in this firmware?

1. fn + Caps Lock + P -- Hold these three keys together for 6 seconds, the Caps Lock key will no longer follow the backlight mode, it will be used to indicate the status of capital/ small letters. This feature was included in the last firmware, but with bugs, this time we have fixed the bug for this feature. Notes: this feature is only the 87 key version as the 104 key version have a dedicated Caps Lock light at the right top corner of the keyboard.

2. fn + L + light effect key (the light bulb key) -- Hold these three keys together for 6 seconds, it will lock the light effect you are using now. To unlock the light effect, press these three keys together for 6 seconds again. Please make sure to hold the fn and L key first then hold the light effect key.

3. Under the no backlight circumstances, if you press the light effect key, the backlight will be turned on. (We add this because there are too many users send questions to us saying "my backlight is not working." "my keyboard's backlight has dead", but the reason for it is they accidentally turned off the backlight and forgot how to turn it back on.
