[Q] Charge port only charges but no data

---

I have a friend with a P7510 wifi edition tablet whose charge/data USB port only charges the tablet. It used to charge AND allow him to move data back and forth to PC or usb stick (with USB dongle) but ONLY charging works now.

Odin doesn't recognize the tablet, connecting it via usb to a computer plays the sound but the tablet is not recognized in windows at all. It is running stock TW. In addition, his tablet has on that broken version of firmware that Samsung pushed out several months ago that messed up screen rotation and Wifi. Booting to his stock recovery gives error so I can't even flash on another ROM.

Is there anyway to get him onto a new ROM and/or to fix his bootloader?

Thanks in advance for any help.

Are you sure you have the correct drivers install on your windows computer?

1000% sure the drivers are correct. I have even tried the tablet on my own PC since I've the P7510 as well. It also does not work with the usb dongle attachment and any usb device like you used to.

The linked picture is what I get when I boot into recovery mode.
