AIGO EROS Q / AIGO EROS K / IRULU Surfans F20 / AGPTek H3 / HIFI WALKER H2

[dconrad]

I am attempting to install the hosted port on a HW3 version of this player. The link to prepatched V2.1 firmware gives a 404 error. I attempted to use Rockbox utility and the V2.1 firmware but the utility closes when I open the files.

Give it another try now, there was a typo in the filename of the file on the download server.

Hello everyone, does someone know where I can find the latest stock OS that can be installed in an originally stock V1.8 firmware HiFi Walker? I believe version 2.0 has been released, but the HiFi Walker facebook page doesn't include it. Mine came with 1.8 and I never updated it. Thanks!

If you reference this chart: https://www.rockbox.org/wiki/AIGOErosQK#Hosted_Port_Installation_40Manual_41, your player already has the latest known original firmware for a hardware 3 player, so I don't believe you can upgrade.

Is there a way to make talk clips for files in the root?

There's no option in the utility to do that.  The only way I've discovered is to copy everything to a subfolder, create the talk clips and then put everything back in the root.

The link is still not working. But I was able to locate the file in the directory listing.

Oh, yeah my bad, I misread it and thought you were trying to install the native port. Glad you found it though!

Could I load the version 2.1 on my HW3 without any problems? I would run it in hosted mode with the added Rockbox. I don't know if someone here has already tried this and could tell me if it worked. Also, is there a video converter to the format MPEG that can actually run in the HiFi Walker? All the videos I've copied ended up in a restart/reboot of the device (it hanged and turned off and back on by itself).

What brand is your player and what brand firmware are you referring to? Each brandname has (frustratingly...) their own version numbers.

To my knowledge a hw3 device will not even accept a hw4 update file (they use different "device name" fields).

I actually have had success using both VLC and ffmpeg to encode videos for Rockbox - I had to mess with the settings for a while until it worked, see https://www.rockbox.org/wiki/PluginMpegplayer.html for documentation.

I found this combination of settings to work when converting in VLC:
Encapsulation: MPEG-PS
Video Codec: MPEG-2, Bitrate=0, Frame Rate=0, Width=320, Height=180, Scale=(blank)
Audio Codec: MPEG Audio, Bitrate=128, Channels=2, Samplerate=44100

But of course there are no guarantees.

Give that a try maybe?

Thank you, I only had to change Bitrate=0 to Bitrate=800. Also, I noticed the video only plays when scrubbing or setting the FPS number value to show (ON) in the player settings.

Is Rockbox definitely a no-go with exFAT?

FAT32 is so slow when copying files.  I boot to the OF when copying to the player, but it's slow.

Any USB drive using FAT32 has savagely slow transfer rates.

exFAT doesn't seem to have this issue.

Incorrect, FAT32 vs exFAT makes nearly no difference in transfer speeds.  ExFAT is marginally more efficient when writing larger files (due to fewer metadata updates) but lless efficient with smaller files.  The limiting factors are (1) USB 2.0 inefficiencies, (2) the USB mass storage protocol itself, (3) the speed of the underlying storage device, and (4) system throughput of the device.  The latter is the limiting factor for nearly all rockbox-capable devices.

exFAT is not implemented for several reasons:  (a) it's largely unnecessary, (b) the stock firmware probably can't read it (or even boot with it), (c) until quite recently required a patent license to implement, (d) it represents a significant amount of work.

Thanks.  I often copy these huge amounts of mp3 files.  I'll get speeds that fluctuate greatly.  I even tried Linux with the same result.  I'm going to try a few different cables.

Might I suggest putting the micro sd card in a reader when you need to transfer large amounts of data? That should be significantly faster I think.

I'll try that.  Eventually though, we're going to hit a wall.  FAT32 only supports up to 2TB partitions.  Even with exFAT, you'd have to use GPT instead of MBR to get a partition over 2TB.

Hey! I just got one of these.

It seems that the AIGO EROS Q variants have moved on to version 2.2. Not sure what hardware revision it is, but some person on Reddit claims hw4 files work.

https://www.reddit.com/r/rockbox/comments/1i4ceya/comment/md1tinu

EDIT: Confirmed on my end, the hw4 files indeed work for EROS Q v2.2 (jztool method on Windows 11 64-Bit). I backed up the original bootloader, please let me know how I can contribute to update the main rockbox page

Good to hear, if you want to go ahead and try the standard hw4 update file just to make sure, it's here: https://download.rockbox.org/bootloader/aigo/native/erosqnative-hw4-erosq_2024.upt. It will either work fine or it will reject it because the device name is different. You just need to put it on the SD card with filename "update.upt" and run the recovery mode from the bootloader.

If you also want to dump the entire flash and share that it would good too. I'll stash it away in case it's needed at some point. Lately it seems like we've been getting fewer and fewer stock update files from the manufacturer.
