SRT8KRMXLT30 - USB Firmware Upgrade - Stuck on Between Step 6 and 7

[randersen]

In regard to https://www.apc.com/us/en/faqs/FA402857/, the display screen is stuck on the yellow Please wait Starting USB Firmware Install Process (not shown in the step-by-step).  It never gets to step 7 of the guide.  If I press the OK button, it goes back to Step 4.  I tried searching and can't find any results related to this issue.

Thank you.

Hi @randersen 

I haven't used the USB method in doing a firmware upgrade, if you are willing to, I do recommend using the UPS Firmware Upgrade Wizard instead.  I have provided the FAQ article below for your perusal.

How do I update the firmware of my CSH, SCL, SMC, SMT, SMTL, SMX, SRT, SRTL, XP and XU series Smart-...
