The hardware tweezers method makes sense to me.

The idea is to short some data lines together of the MLC NAND Flash so the RK270x ROM CODE will always read wrong data from the flash and will never find a valid bootloader. Then, it goes into this RockUSB mode automatically to give a chance to reprogram the whole flash.

This is very cool !!!! ( although i would prefer the soft mode haha )
I never had to open this player yet!

sid6581 I hope you carried out this procedure in case your firmware is different!
Firmware Extraction for new Rockchip RK27xx series players.

This repair tool will get you into rockusb mode:-

The space on the pcb might be for the wolfson audio chip.
the red screen usually indicates something wrong with the BMP0.bin file or it's missing, strange.
Does the player operate blind?, can you navigate and play music?
