Ok.
But as a quick check, does the upt file need to have any particular permissions on it, when it is loaded to the SD card? Does it need "execute" permission? The current permission set is rw-r-r. Should I change it to include X, and try to update the firmware again?
JimZipCode:
Alright, this behavior is more complex than I originally reported.
* I plug the Rocker into my laptop, with the player OFF.
* The screen lights up with the Rocker name, and after some number of seconds it switches over to a USB logo and says "computer connected"
* At that point I go to terminal in my laptop, and CD over to the SD card root
* I copy over the update.upt (the .rockbox folder is still present). I check the filename; and this time I made sure it had X permissions
* I eject the player
* After a moment the player displays the Rocker name, and then says "updating music files" and counts up, to however many thousand songs I have on the card
* That takes a couple mins. Then the player goes to its main screen. If I don't tough it right away, it shuts downSo at this point when I turn on the player, and then browse to settings - update firmware, it says there is no update.
Just now I tried it, but after the player finished updating the music files and shut down, I did NOT turn on the player. Instead I plugged it back into my computer. The upt file is gone! It's already gone. So whatever process reads my SD card and build its database, that process is already deleting my upt file before the player shuts down.
Do you have the player powered on, when you plug it into your computer?
Milardo:
Not sure about the permissions as i didn't particularly change any and i just used the default settings in windows 10 where i put the 2 files in the sd card.
I have connected player both on and off and transferred files, but all this was done in windows 10 os. Do you have another computer to try it on that has windows os?
I did have a bit of trouble getting it to update though, sometimes i had to re put in the .rockbox folder. Also, i'm not able to use the usb mass storage feature, i put in the new update.upt file but the feature doesn't work yet i think?

I have also had strange issues after I plugged the player into my PC. Every time after I unplugged it would try to update the firmware and then it would go to the blue Agptek screen, then flash on and off until I turned it off. It would take 2-3 reboot cycles to get Rockbox to come back up.
I bought an SD card reader for adding music and started using an old phone charger to charge, so I don't have to plug into the PC anymore, and so far no more issues.

I would think it is more likely that the file was never actually written to the tf card instead of it being mysteriously deleted. Tf cards can appear writable but actually fail to hold any data because there is usually cache being kept on you pc that gets written only after you "safely remove hardware" or umount. Also it is not unheard of that some card readers and tf cards just do not play well together and you can get only read only or seemingly random errors. The way I recall these flash devices are made they take any piece of waffer that can hold any amount of data and disable the blocks that do not work. So your 32gb tf might of actually been 128gb waffer. My understanding is that many of the cheaper brands do not correctly mark the blocks that are failing as the flash starts to wear out so get flash that has seemingly ever worsening dementia. I would stick with Samsung evo, Sandisk ultra and perhaps Kingston to increase your chances.
wodz: is there anything you need to debug this mass storage thing?
I did try to build obexftpd which could give another way to access files but I am having trouble building libglib. It seems more recent versions cannot be cross-compiled easily and I do not know what is the original version that they used. I think obex-data-server is also capable of serving files but might be even more complex to compile.
