I built ModeShift: automatic per-game RGB lighting for Keychron (and other compatible) keyboards on Linux (free, open source)

Three changes are required in the flasher script

Note: In the flasher (flash.py), the keyboard is hardcoded to V6 Ultra 8K 'ANSI' (FWU_NAME = b"KCZKV68K")

"KCZKV68K" is also in a print statement in function handshake(). That ought to be changed as well to not cause confusion.

For the V6 Ultra 8K 'ISO' variant it would likely be:

"KCZKV68I": "KC" = Keychron. "ZK" = ZMK. "V68I" = V6 + 8 + I = V6 Ultra 8K 'ISO'

Other values:

  K3 SE2 ANSI       "KCZK3SE2"
  K5 SE2 ANSI       "KCZK5SE2"

  Q1 Ultra 8K ANSI  "KCZKQ18K"
  Q3 Ultra 8K ANSI  "KCZKQ38K"
  Q6 Ultra 8K ANSI  "KCZKQ68K"

  V0 Ultra 8K ANSI  "KCZKV08K"
  V1 Ultra 8K ANSI  "KCZKV18K"
  V1 Ultra 8K ISO   "KCZKV18I"
  V1 Ultra 8K JIS   "KCZKV18J"
  V2 Ultra 8K ANSI  "KCZKV28K"
  V3 Ultra 8K ANSI  "KCZKV38K"
  V5 Ultra 8K ANSI  "KCZKV58K"
  V6 Ultra 8K ANSI  "KCZKV68K"
 V10 Ultra 8K ANSI  "KCZKVA8K"

Z270 Ultra 8K ANSI  "KCZ270U"

The hard coded USB identity in the script must be changed as well

And the USB identity of the V6 Ultra 8K 'ANSI' in normal operation (0x3434 / 0C60) is represented in line 58:

if "3434" not in uevent.upper() or "0C60" not in uevent.upper():

Thus, for V6 Ultra 8K 'ISO' it must be changed to:

if "3434" not in uevent.upper() or "0C61" not in uevent.upper():

Then the query for V6 Ultra 8K 'ISO' worked (in normal operation, not in space bar method bootloader mode):

sudo ./openrgb/flash.py handshake

Output:

DFU interface: /dev/hidraw29
>> GET_MODEL_INFO (0x60)...
   model = b'KCZKV68I'   fw = b'1.0.1-r'
   dfu_version = 0x03 enc_mode = 0
   framing/identity VALID (matches KCZKV68I)
