Shanling Q1

[...] Mine must have been corrupted or the backup process didn't work.

Your backup contains rockbox-info.txt... what appears to be random junk... and apparently a copy of bootloader.q1! Whatever the case, that backup can't have come from a bootable device.

I'll add some basic sanity checks to the restore process to prevent it flashing total garbage, but honestly, I have no idea how all that junk got into your backup in the first place. Especially rockbox-info.txt, since it doesn't exist anywhere except inside the .rockbox folder, and the bootloader doesn't open it.

Yeah, not sure what happened.  The sequence of events was as follows:
1. Used Q1 for 6 months with stock firmware
2. Tried rockbox for a month
3. Decided to go back to stock firmware, restored backed up bootloader
4. Used Q1 for 2 months
5. Decided to try rockbox again, backed up bootloader
6. Decided to switch back, restore failed.

Is restoring a backup of the stock bootloader that you are suppose to make when installing Rockbox the way to revert to the stock firmware?

Yeah, that's supposed to be the tried & true method.

I understand and read all the warnings when initially installing but it would still be good if there was an independent way to return to stock.

But given that the Shanling firmware apparently does not touch/contain the bootloader, there is no such thing as a '2.2' bootloader? Anyone with an original Q1 and the latest tools could donate a bootloader for the greater good.

Having said that, I am very happy with Rockbox on my Q1 and with the option to hold a button to boot the OF, I have best of both worlds.

I've uploaded my Q1 and M3K bootloader backups to the wiki. They're found on the JztoolInstall page in the "Removing Rockbox" section.

Here's a new bootloader release for the Q1, version b4e7c60c6d-221029. Download it here or from the wiki.

This version fixes a few bugs:

The old Rockbox bootloader interrupted the original firmware's update process, preventing OF updates from being installed. This is fixed in the new version, and you can now update the Q1's firmware from the Shanling player app. There are a couple things to be aware of: Shanling's updates don't include the bootloader, so the Rockbox bootloader will remain installed after an OF update. If you want to remove Rockbox you need to restore from a bootloader backup. Second, after the update finishes you will be rebooted into Rockbox. The update has succeeded at this point, but some leftover files will remain on the SD card; you can either remove them yourself or reboot to the Shanling app, which should clean up the files automatically.

The bootloader backup and restore functionality will now display an error message if it looks like the backup is corrupted. The level of protection is minimal but it's better than the old bootloader, which had no such safety checks.

The Linux loader had a bug which added garbage to the end of the kernel command line. This has been fixed.

Hi,

I have lost bootloader backup for my device. Will the one in wiki work?
I have FW Version V2.1

Yes, it should be fine. If it doesn't work let me know.

[Telehubis]

All fine. Updated OF and RB.

Thanks!

Hi

I don't know if this is the right place to report this but Advanced Key Lock is not working since a couple of months, it use to work before but now any hardware button isn't working after lock even with properly exemption configured.

There was a change submitted some time ago which broke quite a few settings for a while before it got caught, this might be related to that. Assuming you're on the latest development/daily build, If you haven't tried it already, you might want to try starting from a fresh config file (try moving .rockbox/config.cfg to .rockbox/backup.cfg), configure it through the menu again. See if it works after that.

After getting annoyed for the n'th time I finally got around to bisecting the bug. It's fixed now in the latest build.

Hi everyone! Thanks for this phenomenal port that I've been using happily for about six month until yesterday ... something broke. Without any further changes (not attached to a new computer, no charging, no manipulations to sdcard etc.), the Shanling Q1 refuses to start. It does show the bootloader and boots into OF. When asked to boot Rockbox, it shows the logo, very briefly shows the text scanning... or similar and shows the logo again. It stays in this state for about 15 seconds or so, dims the screen, later turns the screen off, finally shuts down after a few minutes. I tried:

• Check if the sdcard has bad blocks. Yes, it does (unsurprisingly), so I formatted it with mkfs.vfat -c in order to skip over bad blocks. No effect.
• Tried another sdcard. No effect.
• Tried another sdcard. No effect.
• Tried to reflash the bootloader. No effect.
• Tried to flash the original bootloader. Software refused, claiming it's not a tar archive (which is true).
• Update: Took the wrong file :-( it lets me flash the original bootloader (which works as expected) and flash Rockbox' bootloader (which boots OF properly and leaves Rockbox stuck).

Do you have any hints what else to try? Do you need any more information?

Hi, I'm wondering if anyone has an og bootloader backup? One I got was corrupt, weirdly enough.

Do you mean the original bootloader? I attach the bootloader I have as a backup of my Q1 which runs the firmware V2.2 (see the known issues here: https://www.rockbox.org/wiki/ShanlingQ1Port.html)
