6i24 bricked - How to fix? - JTAG?

I accidentally wrote a -25 bit file to my 6i24 board (XC6SLX16-FTG256) and now the yellow and red LEDs are always on.
I tried using the mesaflash --recovery feature which has worked for me once before, but without luck.
How can I fix this? The manual states that JTAG is an option, but I'm not able to find information on how to do this.

I think you can use the recovery function but there's a bug in mesaflash so you have to lie and say the card is a 6I25...

I already tried this.
In Mesaflash version 3.3.0~pre I get:
sudo mesaflash --device 6i25 --recover --write 5i24_16_justio.bit
Checking file... OK
File type: BIT file
Boot sector OK
EEPROM sectors to write: 8, max sectors in area: 16

Checking file... OK

Error: wrong bitfile destination device: 6slx16ftg256, should be 6slx9tqg144


In Mesaflash 3.4.0~pre I get:
sudo ./mesaflash --device 6i25 --recover --write /home/vaerkscnc/Downloads/5i24/configs/hostmot2/5i24_16_justio.bit
Checking file... OK
File type: BIT file
Error: BootSector is invalid

You have to specifically enable mesaflash to re-write the boot-sector

I restarted my PC and now I get the same error in both Mesaflash versions:
Error: wrong bitfile destination device: 6slx16ftg256, should be 6slx9tqg144

If i have to re-write the boot-sector using mesaflash, how do i enable this?

Are you sure the card was not updated?, your first post suggests that it was.

Edit:

I just retried this:

wrote bad (x25) bitfile to 6I24/ reload,: init and /done LEDS illuminated, card not found

recovered with

sudo mesaflash --device 6i25 --recover --write (good x16 bitfile)

This is with mesaflash 3.30

It does complain about the wrong FPGA type, but only after it has wriiten the flash memory
