Update firmware by copying contents of SYSTEM folder?

parishd · 01-09-2007

My new Dane-Elec miniplayer got corrupted when my pc crashed while transferring songs to it. It would hang on startup with the message "Updating Disc Information..."; it could be soft reset, but not hard reset. Thanks to this forum (thank you, thank you, thank you), I did manage to low-level format the device and reload the latest S1.010 firmware, and the miniplayer is working once again.

I would like to reload the default Dane-Elec firmware, which does not appear to be available anywhere. However, I do have a backup of the SYSTEM folder from before the crash. Can I just copy this backup of the SYSTEM folder back onto the miniplayer to revert to the original firmware? Has anyone tried this?

Thanks very much.

I have never heard of anybody who did that ...

.. but now you know how to low-level format the device, you can try it

Seriously, it would be a good thing if it works, but I don't think so.

But I may be wrong, and I hope so !

I will probably give it a try since I'm confident I can recover if I screw things up again, but I'm going to wait a few days first; I've already had enough excitement for now.

No, doesn't work that way. Files on system folder are just configuration/settings files (no firmware files).

Didn't think so but was trying to be optimistic. Thanks Marcelo.

I think the actual firmware files are stored in a hidden part of the memory. I'm sure of this because, even after moving the system folder's files off my miniplayer, it still only has 3.80 GB free space, 1 file, which takes 600 some kilobytes I think, and the defragmenter shows a file at the end of the memory, too. You can't actually see what the file is, no matter what, though. Yes, you CAN run disk defrag on the Meizu to defrag music files and other files from all that back and forth transferring and deleting, etc... just need to have 15% of the memory free to do so.

At least now you know you can MOVE your system files off the miniplayer and back on again without any harm... just make sure you put the files back before you disconnect from the PC! I moved them off and back on after all my other files were off to get the main system files at the beginning of the memory space... doesn't really do anything, I don't think.

You don't need to worry about background image files, though. You can just delete those if you want. They are the ones labeled like "SYS_MUSICBG". The player uses the default image when you delete the background file.

I don't know if somebody already came up with this.

There could be a way to backup the original Dane-elec firmware from the M6. As you all know, new firmware is copied into the root folder of the disk. When the M6 is restarted, the M6.EBN and resource.bin files are probably copied into a hidden part of the memory like DChronos said, and the 2 files in the root folder are then deleted. Now there is a possibility that the M6 deleted only the links of these 2 files in the file allocation table on the disk. The actual data of these files is not removed and stays on the disk, but there is no "link" to this data.

Now there exists some utilities that are able to recover deleted files because of this (e.g. FreeUndelete 2.0). On a brand-new M6, there is a possibility that you can get the original firmware from the disk by this way.

I couldn't really test this myself, as I don't have a dane-elec and I already copied some music on the M6 which possibly overwrites the data from the 2 firmware files. What I could recover from my newly received M6, was the original resource.bin file, but not the M6.EBN file. (I have version S1.010.2)

The best chance of success can only be on a brand-new M6 without deleting or adding anything on the disk.

Hmm you can disasemble it and take raw rom image of memory. Quite simple to write it here. (:

hello can someone give me those system files because they aren't standing anymore in the system folder and i don't wanne reconnect my meizu of the computer because i think it will be broken again

please help me

Putting those files back on won't fix it, as far as I've read. Try to upload firmware one more time and see if it works.
