Gladiator NXT is seen only in bootloader mode

Postby hiland » Sun Aug 31, 2025 20:16

Hello,

I hope to get help with some problems with VKB Gladiator NXT base.

Recently my VKB Gladiator NXT just stopped being recognized by windows or VKBDevCfg. I also have VKB Gladiator NXT EVO base with omni throttle stick, and if I swapp the Evo base to the Gladiator NXT stick - it works just fine. So I know the issue is with the base.

I tried to follows the recommended steps to reflash the firmware, but with actually regression in results.

At first I was able to enter the boot mode by pressing F1+F2+F3 before plugging in the usb cable. I flashed the firmware (_Gladiator_NXT_v2_19_9.vkb), but the device still wouldn't show in VKBDevCfg. Even more, now I can enter the boot mode only by shorting two boot pins. I also tried the oldest firmware I could find (_Gladiator_NXT_v2_05_5.vkb) with no improvement. Not sure what else to try/ check.

Hello,
can you measure the voltage on the BOOT pins?

That's OK

Is the firmware process complete and error-free?

What firmware was used before 2_05_5?

Do the LEDs on the base or handle light up?

First I tried to flash v2_19_9, then v2_18_2 and v2_05_5. Every time the process was error free, with the only difference in Blocks number. I also tried now _v2_19_F, same thing - device isn't seen in VKBDevCfg in normal mode.
I see the blue LED light up during programming, but that's all I think
