There is a small chance that FW from other player may work on this player. For instance screen driver is mostly compatible, flash memory is also compatible, there may be problems with keyboard and other unpredictable isseus but there is a chance.
For example, I have pentagram vanquish r touch (polish RK260x player) which has the same hardware like Teclast C260, the firmware works and even it became even much more functional after the upgrade.
Though, there is always a huge chance that you will kill your player, and without backup firmware you are hopeless (even with the firmware the player may keep hanging and it wont be recognized by the PC usb port, so be careful - I once killed my player to such extent but after a little play with scissors on the main-board under the metal case I managed to reset flash memory)
