I am sorry about loosing it.

I just never ever bought anything that did not come with any
documentation.? and yes

NanoVNA-H4

I went to the site
/g/nanovna-users/files

and looked around and did even a search and nothing with that name is there.

Sorry.

Also, I took another look at your photo - you have an H4, not an H which means you can only use the H4 firmware on your device.
Not to worry - flashing is very simple: 1. install defuse-demo software (it's not a demo, that's just the name). 2-download DiSlord's 1.0.69 firmware for the H4 (it may be in an archive with other versions), 3-plug Nano into PC and place your H4 into DFU mode by holding in the jog sw and turning it on - screen will stay off but you'll hear the familiar notes to show the PC sees the device. 4-open DeFuse s/w and you'll see in the top left your unit should be in DFU mode. 5-in the Lower LEFT select CHOOSE and get your H4 firmware, then flash with the UPGRADE button (NOT upload). 6-power-cycle & Done
