Hi.
I've received the Clip+ from TomecekGD and it was indeed bricked, but in a strange way. It's a model after refurbishing, with "R" after the serial number, after a very poor reconditioning inside btw. On the beginning i thought that it is the reason of death. I dismantled it, because there was no any reaction to USB cable and then resoldered the battery, still nothing. Then i replaced the battery for the one from the Gogear sa9x00, cause the original one was drained to zero (measured with the multimeter) and the player started to react continuously (dmesg):
[ 889.793248] usb 1-3: new high speed USB device number X using ehci_hcd
[ 904.858619] usb 1-3: device descriptor read/64, error -110
I've restored it in a slightly different way than on the Wiki page (no pads bridging). I held power button for about 10 seconds, until dmesg showed me:
[ 910.237677] hub 1-0:1.0: unable to enumerate USB device on port 3
I knew then, that the dap is in off state for sure. Then while holding the "left" button i pressed the power button, as if i would like to run the OF from the Rockbox bootloader. Dmesg showed me:

Note that in a normal case (OF) you will get:
[ 5723.102817] usb 1-3: new high speed USB device number 29 using ehci_hcd
[ 5723.218294] usb 1-3: New USB device found, idVendor=0781, idProduct=74d1

[ 5723.218298] usb 1-3: Product: SanDisk Sansa Clip+
Then i did:
dd if=/dev/zero of=/dev/sdg bs=512 count=$((0xF000))
dd if=./clppa.bin of=/dev/sdg bs=512 count=$((0xF000))
and it was ready. I've replaced the battery at the end of course and upgraded Rockbox to the current build from 3.11.2. I'm writing all of this because maybe it can be useful to someone in the future.
TomecekGD decided to donate me this player for the purpose of development and testing. Thank you!
