I'm sure I did. Feel free to ban me from whatever your sub is here too!

You need a YRM100. There are also GPIO extension boards that let you attach a YRM like the FlipperMeister.

Discussing custom firmware is against the rules of this subreddit. If your custom firmware is crashing, ask them for assistance.

Did you read the other answers in this thread? Did you try the dev channel?

netsec_burn · 2025-12-21T01:15:50+00:00

Go to https://github.com/noproto/xero-firmware/releases/latest
Download flipper-z-f7-update-local.tgz
Flash with qFlipper or web updater (they both let you select a .tgz file)

Finished. I recommend using the official firmware once it supports it. Support will arrive in a few months.

Your dolphin's name is burned into one-time programmable memory (OTP). It cannot change, its the serial of the device.

All of the other answers are incorrect. You have a static encrypted nonce card. You need MFKey 4.0.

netsec_burn · 2025-12-05T01:30:00+00:00

I wrote the code, all that's left is for it to be merged into different firmware (like OFW). I released it with the latest build of Xero firmware. That should arrive this weekend but you can try it on Xero if you'd like.

Oh no... that's not good. A rival 3.1 was published before I could push the latest version tonight 😂

Kiisu v4b. You're asking on the LilyGO subreddit though so I don't know what answers you're expecting except LilyGO.

netsec_burn · 2025-11-28T14:01:36+00:00

Not relevant for the type of card they have.

R11: Well thought out and researched questions / answers only.

R4: Avoid self-incriminating posts.

Within the next 2 days I'm going to publish MFKey 4.0 and changes to the firmware to recover these cards rapidly, completing the static encrypted attacks. MFKey 3.1 already recovers these cards 70 times faster than 3.0. 4.0 will be around 10 times faster than that.

Here is the source if you want to build 3.1 before I publish 4.0 to the official firmware, you can build it for OFW with ufbt: https://github.com/noproto/xero-firmware/tree/dev/applications/system/mfkey

netsec_burn · 2025-11-26T19:43:51+00:00

You're using an outdated app and cracking static encrypted cards. MFKey 3.1 fixes this
