We actually did start probing stuff around, and we are missing something in the "full restoration process", so we're stuck for now.

Sahara protocol still is a mystery for us, and we can't get pass an error.
I think we don't actually have the right programmer_firehose.mbn for our device, but if it's not this, I'm basically out of ideas. (we might need an "QFIL expert" on this)

I still don't have my device around and feeling dumb about this.

Anyway, all the files and tools required to try probing around are in my gdrive and I can PM the link (as I still can't post it right away) if anyone is interested.

Thanks for trying to help or actually help everyone !

Cheers !

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 !


i was able to unbrick my device

requirements:
samsung drivers installed
windows 10 (i have the windows 10 pro installed)
oem unlock
usb debbuging selected prior to brick
install the latest samsung drivers
install fastboot/adb drivers
stock-boot.img provided by minotauri



the steps are as follows:

  1. the device must be in recovery mode an plugged to the computer. I was on stock recovery
  2. open device manager in windows, look for anything android and delete it and choose to delete the drivers
  3. refresh device manager for new devices (keep only the xdp-300 android connected)
  4. right click on the android device and click on update drivers
  5. select browse my computer for driver software
  6. click on let me pick from a list of available drivers
  7. unselect show compatible drivers (if you see a samsumg driver here, select it. If not try generic windows adb drivers)
  8. seletct google adb drivers (this is the one that worked and it's under samsung drivers)
    i performed the steps 1 through 8 a few times until the computer categorized the device as adb
  9. open a command prompt, navigate to the directory where fastboot is installed and type: Fastboot devices (you should have a device listed here)
  10. type: Fastboot oem unlock (this unlocks the bootloader)
  11. after copying stock-boot.img to the root of the your fastboot directory, type: Fastboot flash boot stock-boot.img (reboot)
    after the reboot you should see normal boot
  12. if you want twrp and root follow the instructions here: https://forum.xda-developers.com/and...layer-t3902949 all credits go to anthony nguyen.
  13. i installed twrp the latest supersu pro, viper4android, root browser, busy box pro and everything works perfectly.
    good luck to you e n j o y ! ! !

i am not an android programmer so i won't be able to help you from that perspective, but i a software engineer so i maybe able to answer some questions.
There is no guarantee this method will work for you but it did work for me
I can provide a TWRP backup file for you to restore your device

Here is a few items to note about the image:

You must have twrp installed and accessible in order to restore this image.
First time booting after the restore will take a long time, so have a cup of coffee and let it do it's thing.
Every time you boot the OS will perform application optimization, it doesn't bother me so I have not even looked into it.
After you boot connect to your WIFI and open Google Play to set up your account
If you want to use Viper4Android, download and install busybox, then open settings, go to apps and disable Musicfx, then reboot and turn Viper4Android on.

Good luck

Thanks for answer and sharing your files. Unfortunately, there is some error when trying to restore in TWRP.
I packed all the items from your disk in ZIP and downloaded to the SD card .
I'm getting an error about the content: no MD5 file found Failed to map file'/external_sdxxxxxx-Full BACKUP.zip'
Error instaling zip file
. Do you have an idea why this is happening?

You need to change settings in twrp not to check md5 checksum, if it doesn't work then i'll create one with checksum.
