Hacking JR Programmer Woes

H Slick · Mar 11, 2021

Hi Guys,

I'm kinda tearing what little hair I have left out over this - please tell me there's a silly step I've missed somewhere.

I can't get a green light from my JR Programmer V2, regardless of the configuration of the switches. For redundancy, I'll add a picture of the model I'm using.

I'm using Windows 10 - in the device manager, it shows up as a "USB Input Device" under the Human Interface Device tab - not Pruftechnik as a USB device like multiple people with the same programmer report.

I've restarted with signed drivers turned off, installed the drivers successfully, and I still only get a red LED, regardless of configuration.

The JRunner program, V3.0.0, does not show the logo as expected, but will recognize it as a bootloader with the switches in the appropriate configuration.

I've tried this on two separate Win10 installations now with the same results.

Have I done anything wrong, or should I throw in the towel and buy a NAND-X ?

Try it on Windows 7 32 bit?

64 bit stinks in that regard and Win 10 has shite compatibility with decades old tech.

Great, thanks for the advice. I'll give that a try tomorrow!

@DinohScene

Okay well I went the the tedium of doing a fresh install of Windows 7 32 Bit and finding a compatible version of J-Runner.

Exactly the same thing. Only recognizes it as a bootloader and never shows a green light.

Do you have any further advice?

Running Jrunner v0.4?
I think your programmer must be faulty then, hate to break it to you.

Tbf I never had a JR programmer, me NAND-X continues to serve me well ;p

I was using v0.8 on Win7 - 3.0 was crashing every time I opened it, so before I gave up I tried 0.8 - still no luck unfortunately.

NAND-X is on the way, hopefully that will be a different story.

Okay, final update hopefully - I got a NAND-X programmer from chipchopmod.co.uk - no hiccups using that whatsoever.

It was a little tricky finding the NAND-X drivers, which are known as nandpro_20d - I eventually managed to find them so I put a download link to that here for anyone else who may need it.

Cheers, I'll see if I can mirror it on the download center.

Glad to hear it worked!

On win10 Disable driver signature enforcement,

Also sometimes you gotta plug it in and unplug for a few seconds then plug it in slowly

When you plug it it it should flash red then immediately hold solid green, then it's ready

Mine sometimes will have this issue too, it goes red as soon as it's plugged in

Thanks for responding. Unfortunately I have tried all of this already!

I think I will probably sell it as "not working" to someone who might be able to get it working on their PC, or fix whatever is wrong on it. The NAND-X has been serving me well, and has just helped me RGH another console
