Hi @Thanish24,
Thanks for reaching out. I’ve noticed another user who seems to be experiencing the “flash failed” error you see, though I’m not able to replicate it myself when flashing the Tails image.
I’m reaching out to our Etcher team to find out if there’s more we can ask that will help us troubleshoot and get to root cause, so stay tuned and we’ll be back with next steps soon.
