I was wondering if anyone on this group could help me out with getting my QR20 upgraded.? It is showing HW: v2.0, SW: v2.0.1 and I would like to get it to one of the newer version 3 firmware versions, but I am finding some conflicting information out there.
1. I asked Radioddity support, they said "the QR20 with V2 hardware cannot be updated to V3 firmware since there is a hardware difference. We recommend not upgrading to avoid damage to the radio."
2. On the Radioddity web site they have a PDF with instructions that indicate you need to "Disconnet the UV amplifier power cords" and use "Dfuse Demo software" to do the upgrade via USB.
3.? In this forum post on linuxslate.com it says "Q900 Radios that show HW: 2.0 (or later, presumably) can be updated using a USB Flash Drive. Installing a separate Bootloader file is unnecessary at this time."
I was just wondering if anyone here has done the upgrade either by desoldering the U/V amplifier or just using the flash drive and skipping dfuse altogether. I'd like to get the firmware upgraded but I'm not familiar with the rig and I would rather not brick it.
I appreciate any help you can give!
