I'd appreciate it if ya'll spare a moment to humor a clueless dude in his struggle to get Rockbox on his Hifi Walker H2 (V2.0).
I'm doing my best to follow the instructions. I extracted the RockboxUtility-v1.5.1 file into the SD card. I tried both the daily build and development versions. When I hit the "install" button, it gives me a popup titled "prerequisites" and instructs me to "provide the correct version of the original firmware file." When I hit "ok" and select the bootloader update "erosqnative-hw4-erosq_2024," the RockBox utility just crashes and the window disappears.
I also attempted the manual method in the instructions, but the when I went to select "update firmware" on the device it just said "no upgrade file found."
I reformatted the SD card using the system restore menu, so that shouldn't be the issue. This is 1000% not my area of expertise so I'd be grateful for a wiser set of eyes to sanity check what's going on here.
