I've seen reports of "too big" cards having issues, lemme see what I can google

But if you have a smaller one around, try that in the meantime.

"User did not grant permission" is your clue. Make sure it doesn't present you a prompt while picking the drive or while flashing that you never agree to, or that your drive is write protected.

(User is you)

I’ve tried 4 or 5 different drives. No different.

I don’t even know how to write protect a micro sd.

Try running as admin, or temporarily disabling UAC?

I’m trying Rufus. Looks to be working. At least no errors yet.

Rufus Worked!

@glacial oyster I’ll bet it a Windows 11 security issue. Nevertheless, Rufus has me rock in and rolling.

i have no problems on Win 11

Rufus doesn't do a verification pass IIRC so it doesn't catch SD card corruption issues

Brand new SanDisk Ultra 32Gb. And I tried 4 other Micro SD cards ranging from 8 Gb to 256 Gb.

8 is too small. But yeah definitely sounds like a permission issue.
