Hi !
I've attempted to deal with the devil by trying to root my Pioneer XDP-300R resulting in a bootloop problem (device is stuck on "Powered by Android" screen).
I attempted to flash a boot.img for a Onkyo DX-P1 (which is the same firmware), and still I haven't progressed.
No firmware, update or imgs are provided on Pioneer's website.
I still have access to fastboot (OEM is LOCKED, so I can't boot TWRP and such) in bootloader mode and adb push (no shell) in recovery mode.
Do you guys have any idea how to sort it out ?
Edit :
I managed to make my device go into Qualcomm's emergency download mode.
Here's how to :
1 - Make sure the device is completely off and unplugged from USB.
2 - Install QPST V2.7.474 (not enough posts to share url, but I can PM it).
3 - Install QDLoader Drivers (same as #2).
4 - Simply press and hold the "Play" button while connecting it to your computer, the device manager should see a "Qualcomm 9008 port" listed in Ports while the player's screen stays black.
5 - Do the Carlton (important step !)
Now, if anyone possessing a FUNCTIONAL AND ROOTED Pioneer XDP-300r is reading this and willing to help, can you get in touch with me ?
Together, we could manage to save all the other devices from soft-bricking.
All I would need from you is some time, hard disk space and patience to sort it out.
Please <insert_your_name_here>, you're my only hope !
Edit #2 :
Thanks to minotauri's great help, we managed to get a FULL rom backup, split the partitions to files and generate all the files needed for QFIL.
ErrOzz has been given access to this, hoping that he'll try it out soon.
If that works, I'll link you the files and write the walkthrough to bring you DAP back to life.
minotauri's contributions are not in rest tho, he managed to also successfuly patch TWRP for the device, so anyone can securely flash things from there now.
For anyone reading this thread : you're not the only one who screwed things up, we did too but we might have the cure. Hang in there !
