AIGO EROS Q / AIGO EROS K / IRULU Surfans F20 / AGPTek H3 / HIFI WALKER H2
speachy:
I finally got around to recreating the mass hibyos firmware patcher environment I occidentally deleted a couple of years ago. As well as regenerating almost all of the existing firmware images, I added in the ones that I've come across since then:
Eros Q v2.0 [ Note that the Eros Q II is a different player. Two different players, actually, thanks to the touch variant ]
HifiWalker H2 v1.1, v1.3 [*1] v1.4, v1.6, and v1.8
(These are still using the bootloader builds from 2020-01-08, same as all the other patched binaries. If there's a need to update that, I will)
I am still missing the following firmware images, so I can't generate patched versions of them:
Eros Q v1.9
HifiWalker H2 v1.7
Surfans F20 v2.2 [*2], v3.0, v3.1, and v3.2
If you have a device with these versions, you could try contacting the manufacturer and ask for the update package, and pass it onto us.
There's also the HifiWalker H2 Touch ( and its sibling, the Eros QII Touch ), but those aren't handled yet.
[*1] I replaced a hacked v1.3 image with the official update
[*2] There was already a patched version of this, but I don't have the unpatched original any more.

Hey all sorry for replying late
I took advantage of Ali and amazon sales and got a few more Eros Q and F20 units.
I have a good bunch now, both from ~2022 and now these more current batches.
Eros q is on ofw 1.9. I'm using the native port with the newer bootloader that was re-posted a few pages back.
Can I use this to dump a firmware image for you?
I need to double check my newer F20 units but I'm pretty sure they're all on ofw 3.1. Haven't gotten around to messing with them yet but again would be happy to dump any and all files for you all.
A few more things to note:
The Bluetooth on the official firmware works both ways. Meaning you can use it as a Bluetooth dac for your phone etc. Very cool.
While usb c dac dongles mostly work, some dont and I can't figure out why. For example my Abigail dongle
works but my Fiio KA3 doesnt.
The official firmware has a gain setting but it doesnt seem to do anything lol. Does this translate to rockbox in anyway?
On the newer F20 models the screen is crooked, mainly because its not held down tightly enough. I gave it a few good palm smacks and it shifted into place.
If opening these up wasn't such a pain in the ass I would just tighten the screws or add a bit of tape but for now I can't be assed.
Still would love for someone to design a 3D printed back that screws into the existing mounts to replace the glued on glass/acrylic + plastic bs that both models have. Would go a long way in terms of future proofing and battery replacements.
I recently saved my ancient clip + from an expanded battery and these clipped/glued cases dont pop off from the pressure so it can crack your screen and stuff.
Anyway, just let me know how I can dump the firmware and stuff for you.
If someone can add those newer bootloaders to the wiki page that would be great as well.

I believe so, but I couldn't tell you precisely how. (In the past I disassembled the unit, got a serial console while the OF was running and manually dumped the flash to the SD card)

Yeah, that would be good to have as well.

The latter either doesn't claim to be USB Audio class or it has some sort of quirk that's not recognized/handled by the fairly ancient linux kernel+drivers in the OF.
coomer101:
The rockbox recovery menu on my eros q 1.9 has "dump OF player" and "dump entire flash" options.
Would either of those give you what you need?

"dump OF player" will probably do the trick!
