How can you test a wall charger with a USB-C connection to see its capabilities as it seems to work only over the USB-A connection? I tried a few USB-A to C cables and it would not even power up. Thanks

Fun fact for you. You can actually update FNB58 without a USB micro cable. Just hold the OK button and plug it straight into a PC. Moreover, you can update with a Type-C cable too! I think bootloader mode works on all input ports!

Mine kept freezing/stopping during the format and upgrading process.
But each time I would have to unplug and replug it back.
Each time I would restart the process it would go further.

I need the computer software for the FNB58, the link that was provided for the site only has docs.

Hi TechCorner, I recently purchased the FNB-58 USB tester. There are a few glitches, but in general I like the product.
Wanted to see if others are facing the same problems I am:

1. with the FNB58 connected to the PC, and the recording software ("USB Tester Tool") running, I find that the recording software abruptly stops communicating with the device. This happens after about 20-30 mins of recording. Everything just freezes on the software side. The device itself still works fine. I am running v0.0.6 of the software (I think the 'About' tab erroneously says v0.0.5), and v0.67 firmware on the FNB-58

2. The bigger issue is that after about 1 week of use, the FNB-58 screen suddenly went blank. I see nothing on the screen, and the navigation buttons don't produce any beep. The device connects fine to a computer, and I can see all measurements, but nothing on the FNB-58 screen. I know the screen is working, because I can boot the device into bootloader mode, and see the update instructions there. I tried re-updating my device - the re-flash completed, but still, nothing on the screen when I try to boot in "App Mode"

I am updating firmware. It started successfully but stuck on 13 %. More than 5 minutes waiting without any further progress. What to do now? On the device display I can read: Erasing sector 100%. So, I guess iF I disconnect this device, it will be bricked then? Is any chance to revive it after?

i dont have that big software on the pc either. can you put a google drive link to them ?

Thank you! Can you explain how to set the device (and what cables need) to metering charging voltage and currrent? In addition, when you use the small PD button?

How about another more advanced video giving more in-depth explanations like what each protocol acronyms are, how and why one would use triggers, the PD listener the PD converter or the USB-C E-Marker? Perhaps, you could make a tutorial on how you would use the FNB58 to diagnose a real world problem?

Can anyone tell me where I can read on the FNIRSI FNB58 whether a device supports PPS? The device should actually be able to read this, but I can not find it.

Thank you very much for making this. Would have found it eventually but this makes it really easy!

Hi, I tried to upgrade the firmware (v0.67) following the exact same steps, but I am never able to complete. It fails at various percentages, sometimes in the erasing part and sometimes in the upgrading part, but it never went beyond 35% of the upgrading part. I also noticed something peculiar: as soon as it fails, one character from the display disappears (for example, "1. Erasing sector: 14%" becomes "1. Erasi g sector: 14%" (in this case, the "n" disappears). So now, unless I managed to find a way to overcome this odd upgrade problem, I am stuck with a "bricked" FNB58. Do you know if I can chat with one of their support engineers?
