7i76 Error: BootSector is invalid

It is my first time with the 7i76e board, because of a defect in the cable assembly, the writing of the .bit file was interrupted, now it is an error BootSelector is invalid. How is it repaired? Thanks a lot

1. if you power cycle the 7I76E, do you get a red /DONE LED?
2. if not, retry the firmware update
3. If you get a red /DONE LED on power up you can recover using the secondary flash memory:
A. Power done the 7I76E
B. Move the Jumper W9 to the "DOWN" = S position
C. Power up the 7I76E
D. Immediately move Jumper W9 to the "UP" = P position
E. retry the firmware update
F. NEVER update firmware with W9 in the DOWN = "S" position

Note that to fix a broken boot sector, you may need to add
mesaflashes --fix-boot-block option (depending on mesaflash version)

I have 3 red LEDs. that is good ?

The red /DONE LED is the only one significant here

well that's no entirely true, if you have a red POWERFAIL LED illuminated, you have hardware issues

There are only 2 Red LEDs on a 7I76E card:
CR2 = /DONE
CR12 = PWR FAIL

There are three Yellow LEDs:
CR1 = INIT
CR8 = FIELD PWR
CR13 = PWR

and 4 Green "user" LEDs

I have on the power led and the field pwr led, after turning off and on the 24v source

When linuxcnc starts up, the red INIT LED will light but it doesn't turn on DONE

What should I do exactly?

I'm a bit confused here

I thought you were trying to update the 7I76E firmware

yes !!! yes, that was what I was doing, I was writing the file 7i76e_7i76x3d.bit and it was interrupted, then I stayed in this situation

Did you succeed in updating the firmware?

no, I still have the same alarm
