Yes, I'm trying to revert native Rockbox installation back to stock then to hosted mode. I've observed that I boot into Hiby more often because of working Bluetooth.

The stock update file does not write the bootloader by default. But we can simply mark it to be updated and then run the stock updater.

Ah, that explains a lot. I'm not sure the stock updater actually does anything right now. The way I remember it working was rebooting and showing the progress bar while applying the update.

If I boot into Hiby and run an update it almost immediately reboots into Rockbox and does nothing.

Alright, give this file a shot. Put it on the SD card named "update.upt" and then, with the device off, hold VolUp + Power, and then select "Aigo Recovery". It should run the updater then and you'll be working with a totally stock player. (fingers crossed for no weirdness)

I'm new here, and I've been trying to restore my V2.0 back to stock bootloader.  I know the above conversation was about restoring a V1.5 H2, but did you do something to the 1.5 bootloader to come up with that updater above? (EDIT: I guess this is just a modified 1.5 update file using a script)   

Is there some way to get a V2.0 device working with the stock bootloader as well?   I tried the one for V2.0 and I got bricked, so I had to use 'jztool' to restore the Rockbox bootloader.

Yeah, we can do that I think... I'll see if I can get one to you after work. I think I will try and see if we can just get all the "uninstall" update files up on the downloads page, or at least linked in a google drive folder somewhere.

[rednakes]

@dconrad  that would be great!

I wonder if a v2.0 flash image backup can be bundled with the stock bootloader, so that we have a fake update file that can allow a full restore to stock. I remember doing this with Android backup images years ago when I was developing a tool for custom ROMs, though I don’t know if the same idea can be applied here.

It would be nice for a native installer (the new way, with update files) to perform a bootloader dump/backup by default. I did a native install before I've figured out Rockbox recovery, jztool and other stuff and lost my stock bootloader this way.

It sure would be, but in order to do that you would need to use jztool, which defeats the entire purpose - if there are any interactive backup options in the stock updater, I am not aware of them. As far as I am aware, it can only read from the SD card and write it to the internal memory.

(I would love to be proven wrong about that!)
Edit: Looks like there are some "script" pre-install hooks that might make this possible... And there is also a "install only if newer" feature I wonder if we could use... In either case, this is well beyond what I know about swupdate at the moment.

I should also add, if you feel like looking into it, patches are always welcome

I understand this is about a Hifiwalker H2 V2.0, right? I just want to make sure, because a Hifiwalker H2 V2.0 is different from an Aigo Eros Q V2.0!

Well, I went through the process of manually creating an update file... You can try it here at your own risk. Link

Put the file on the SD card as "update.upt", and then, with the player off, do the following:

• Hold VolUp + Power
• Run "Aigo Recovery"
• The device should update and then reboot into the original firmware

Please let me know how it goes!

Thanks for taking the time to help.  Unfortunately it didn't work properly -

It shows a screen with "Updater V1.1" with a progress bar saying "Upgrading...".    When it's done after about a minute, it reboots with the Hifi Walker logo, and then proceeds to repeat the same upgrading step unless I remove the SD card.

If I remove the SD card it says "Updater V1.1". "Insert TF Pls"


I can however recover by loading the Rockbox boot loader with jztool.

EDIT:  Yes it’s a Hifi Walker H2 v2.0

[rednakes]

BTW after the recovery update, it doesn't allow me to boot into the stock HiFi Walker system anymore.  I can only boot into Rockbox.  I still have my flash.img but I don't know how to use it.

Actually, never mind, I got my Hifi Walker H2 V2.0 back to stock!  I built my own update.upt and went into Rockbox recovery and selected "Aigo Recovery"

Here's the link to the HiFi Walker H2 v2.0 updater, which will restore you back to stock firmware. It can be launched from Rockbox recovery (or even when you don't have Rockbox installed, just press Power + Volume Up).  Use at your own risk.  It's working for me though.

To build it, I followed the instructions by user 'disrel' in this thread:
https://forums.rockbox.org/index.php/topic,55233.0.html

On my Mac I had to install UTM (for virtual machine) and then added an Ubuntu Server VM.  Then I was able to perform all the actions on a flash.img backup.

[dconrad]

Well, good thing you had more luck than I did! I'll download your update file and overwrite mine with it.

[rednakes]

BTW I notice the controls for most of the games are missing.  For example in Invadrox the Play button acts as the Fire button, but I am unable to move.  I assume the track wheel would control Left and Right  normally.  Is this something that can be fixed in this Rockbox firmware?

[dconrad]

That might actually be something that got fixed in the last few days - here's the patch - https://git.rockbox.org/cgit/rockbox.git/commit/?id=68c3fbe263a30fefaf46f5bba655810ae26584f2.

If you're running a build from before that, you might want to update to the latest (or 4.0) and see if it's fixed.

I’m unable to update because I get the message “Error loading Rockbox file not found” when I reboot with the latest files.  The problem happens with both a manual install of .rockbox as well as with Rockbox Utility.  Are the necessary files for these devices in the latest update?

You're now using the Hosted port, correct? Are you using the build for the Hosted Port then? Try grabbing it from this link: https://download.rockbox.org/daily/aigoerosq/rockbox-aigoerosq-20250402.zip

Otherwise, we can dig into what's going wrong, but it's usually that mixup.

I did use that file from the daily builds, but no I didn't use the Hosted port. I just downloaded the zip file for the build and unzipped it on top of my original .rockbox folder.  I also tried unzipping it by itself without an existing .rockbox folder.  Then I tried with the Rockbox Utility.

For the Hosted port, do I need to install the patched firmware image?  Seeing that there is no hw4 for HiWalker, do I install the Surfans 3.4 version?  OR we need to patch the v2.0 H2 updater that I made?
