Bricked TP-Link TL-WR841ND v5.4 - Cant access U-Boot

I bricked my router when trying read the SPI flash with a clip.
Its not possible to enter the U-boot with "TPL" anymore and wounder if someone having a U-boot or original firmware dump for my TL-WR841ND v5.4.

Firmware from TP-Link website doesn't containing a U-boot for my version.
