Is it a new card?
If so, is it formatted correctly?
It’s formatted to FAT32
It’s not new, it’s a few years old (16gb). I just reformatted it to FAT32. Removed all files, except for the firmware file .dfu
The Coldcard will not recognize the file on the card
Reformat. Re-download. Insert the card with the CC powered off. Them power it on.
Attempting now….
Followed steps - now it won’t even recognize the card at all. JFC.
Ugh...
Did you have your seed phrase backed up anywhere else?
I think I’m just going to try doing this on the terminal
Thank you for helping me
Keep me updated. This sucks. 🫂
This is the absolute fucking worst
It is the very least I can do. I was helped. I will help those I can.
Yes. Yes, it is. I was fortunate. I am gutted and angry for those who are boned.
What size is the micro SD? It won't recognize larger ones. I forget the cutoff. Could Google it. I've used 8GB and 16GB. My 200GB doesn't work in a Coldcard.
Asked the Googs. Google says 32GB is max.
Simple step: insert microSD before connecting cable and booting coldcard
A thing to try: get a different SD, if it recognises, format the SD card using the coldcard option. Then put that into your computer and move update file to SD
Try to update to an intermediate version (e.g. 5.2) and then to latest. There seems to be an issue with large version bumps.

Are you trying to update via an SD card - can’t see one inserted.
If for some reason you’re trying to update via a usb connected to the laptop then you probably have the USB disabled. In that state it only functions as a power source and can’t read data.
Hmm guess I should read. I would try reformatting the SD card on the coldcard and trying again once you copy the firmware on to the sd again.
What’s on the end of the wire ?
I had the same issue. I just used it to sign the transactions to a new wallet and ditched the device.
Got the seed words? Just import them to an offline machine. Make a TAILS drive real quick. Or just risk going to a hot computer for a moment to get them off? And put them immediately into a new wallet generated offline. And then a new wallet generated by dice.
TAILS is the way IMO.
I didn’t have this exact issue but had a problem where it got stuck trying to start the firmware upgrade. Try unplugging, taking out the SD, wipe the SD, and just restart.
I can't help but can sympathize. The same thing happened to me yesterday - could read the SD card and then suddenly couldn't (tried cleaning up the SD, unplugging, etc). On top of that, it wouldn't let me wipe the current seeds. I tried multiple times in a few different ways, both before and after the firmware update. After all the warnings that I agreed to, it just announced "aborted" and that was that.
I don't have much of a stack so wasn't dealing with the panic of many folks, but for me it was multiple Coldcard failures on top of the entropy problem.
use dice roll. u don't need new firmware to use dice roll path
Solved - thank you homies
I tried 2 different size microSD - 2 gig and 16gig, neither worked. I ended up using Mac terminal to update firmware on Coldcard, got new seed generated using 99 dice rolls. What a giant pain in the ass. I love you guys.
Tried simple step- didn’t work.
Will try the other idea in future if needed. For the firmware updated using Mac terminal. Thank you!!
I got it sorted – used Mac terminal
Thank you friend
I got it sorted thank you
The additional failures was like getting kicked while down
I wish I would’ve known this a couple of hours ago hahahahh
🧡
Use the cold card to format the SD card, then copy the file to it, then "bless" the file
Glad you're good
Scary 24 hours not gonna lie.
Make sure you format the card as FAT32. The coldcard on-device format option uses the correct format
What’s weird as I did that and it didn’t register on the device for some reason
You're taking a big risk further entrusting your stack to a brand which has irrevocably lost the fortunes of nearly 1,200 #plebs.
My advice (do as you please, of course): forgo that hunk of plastic completely and procure other options.
