AGPTEK Rocker

Story:
Last week, Thurs or Fri, I was cooking dinner while playing my Rocker thru my external speakers, when it ran out of charge and "died". After finishing dinner, I plugged a charging cable into it, and an error notification popped up. I didn't worry about it, figured it had stopped in an error condition and would reboot fine when it was charged up.
Next morning the error screen was still displaying, but I barely glanced at it, just unplugged and turned the player off. When I powered up, the normal bootloader choice appeared, but when I chose Rockbox it said it could not boot Rockbox. I tried a few times. It did boot into the "Hiby player" just fine, but not into Rockbox. When I booted into the original firmware, it couldn't find any of my music. When I plugged the player into my computers, it would charge, but the player would not be detected by the computer. I tried it on a laptop running RHEL7, and on a desktop running Windows 7. Neither machine detected that anything was plugged in, though the player itself said it was "connecting to computer", and it started to charge. I took out my microSD card and put it back in, no joy.
Eventually on Sunday I bit the bullet. I used the orginal firmware to restore factory settings. I used original firmware to re-format my microSD card. Copied the update_rb.upt file over (I had it stored on one of my computers), and I unzipped the Rockbox dev build from here. Booted original firmware, turned off, then booted Rockbox. Success! Recopied all of my music over, which took an hour or so. Now player seems as good as "new", ie good as originally Rockboxed.
I dunno if this anecdote is useful to anyone. Something during normal usage cycle "fried" (technical term) my microSD card, and required reformatting and reinstall of Rockbox to restore to service. But I don't know what the "something" was. Also it didn't brick the card, I was able to reformat and continue using the card. Just lost all the data. Wish I had paid more attention to that original error message, captured it.
Thanks a lot for merging upstream. Having the dev build available was super useful.

First of all, I have a question about the build procedure on github ( https://github.com/wodz/rockbox-wodz/tree/agptek-rocker/tools/agptek_rocker/ ) - I have to provide an existing update.upt from the manufacturer and then it's gonna get patched, right?

Yes, you need to provide original update file and it will be patched with bootloader. This is one time process.

Neither of those worked for me, I get "Insert TF pls", "Updater V 1.1" and "v_v Failed".

Direct this questions to people providing those update files.

Its a pitty you didn't note what error it was. Anyway if bootloader popped up it would be enough to run checkdisk on SD card/reformat it and unzip rockbox on it. Flashing patched update.upt is only needed to inject bootloader. Anyway FAT filesystem is rather sensitive to power outages.

I didn't know that. Thanks.

Yes.
I apologize for the vague nature of the report. I only posted so the info would be out there, in case other users report something similar. Then someone might say "that sounds a little like what happened to JZC" and maybe help spot a "trend", if there turns out to be one.
Great port, by the way.

Ok, so I was able to patch update.upt. But I'm still not able to flash it, since I could not find any firmware that would flash on my unit. I get the same "Insert TF pls", "Updater V 1.1" and "v_v Failed" every time. Tried 2 different cards formatted by the player.
