Does anyone know how to get the BOP firmware off of a SanDisk sport clip +? Mp-3 player with an Android phone? I'm just tying to get it back to factory, or put new firmware on it. Rockbox won't work.

So did you ever figure it out?
I did figure out that I can't do it with this cheap ZTE phone. I'm in prison so I can't just run to the store and buy a galaxy. Lol.
I'm working on getting one though. Maybe a week or so. In here they are 3k. I'm guessing you also don't know? I have a good idea for it. But I need a phone that will recognize that something's plugged into it.

Yes it can't be done with ZTE because of OTG cabalities. I can add music with no problem. I can also add days to an expired mp3 by shortening the board. But the wait is around 30-60 days before I can power it up. I want to know how not to wait. If you know how?

How are you adding days and music? What do you mean by shortening the board?
Are you saying you can do this with a ZTE? How?

Again you can't add music with ZTE. You need another phone like an LG or TCL then you need the right app to move the music to player and finally you need to make the cord. The adding days doesn't work ever single time but it's basically getting a wire to the positive side of battery and then to a chip on the board.

I already made a info transfer wire. Which chip on the board, and which leg? Any resistance needed?
  • And which model player are you referring to? If it's the old Sansa clip with green display, an ordinary rockbox will run it. You'll delete the current firmware. It's relatively easy to do that one.
  • But if it's the sport clip with color display, the firmware is a monster. Real hackers can't break it. As far as I can tell. No one has ever hacked the installed ATG firmware and got it working or off of it.
There's only one way I know that works, and it requires a computer.

We've had success by going positive to some transistors that sit next to the memory chip. We understand that they control the actual buttons but don't understand why sometimes it works and other times it doesn't. So we are not sure just yet.
