help ! revive a bricked gtx 560ti

[wali2]

i tried the Grounding Sub Vendor Pin method using tweezer , and it worked at a certain point ,because the gpu was bricked and not posting and not detected by windows or nvflash when i put in secondary pci e slot
i use bootable usb with nvflash ,(because the windows version of nvflash doesnt work at all) ,i tried the following command : nvflash --index=1 -j -4 -5 -6 bios.rom (i create autoexec file containning command line using notepad and copy it in usb )
nvflash sees the 560ti when booting first time ,but stops at message overrinding strap and nothing happens and nvflash shows : -:>-
nvflash doesnt recognize the 560ti after this message for example i type --list ,it shows the first gpu adapter and not the 560ti (he sees the gtx560ti at boot only),
edit : the gtx560ti was bricked by a bad flash
edit :nvflash says unkown eeprom
edit: nvflash sees the 560ti when typing --check

If that doesn`t fix it you need a new card.

...,(because the windows version of nvflash doesnt work at all)...

The "j" command has been removed from recent NVFLASH versions if you had tried one of them.

Another option would be a hardware programmer as described e.g. at
