Sd Card Serial Number Clone

Is there a way to read the CID of a micro-SD card Questions and Answers. PSN' which is written in the CID Register of a microSD-Card; the Product serial number PSN.

(tl;dr – skip to bottom for instructions, see also ) The CID register on SD cards is supposed to be read-only, which means it can be used to lock devices to specific SD cards, preventing the user swapping them out, which is very annoying. This can result in you being stuck with a smaller card than you’d like in a device or not being able to use a backup in case of damage. I’ve spent a while trying to work out how to change the ID on some cards. There is surprisingly little info out there about this, when it’s easy for other devices. For example, if you want to change the supposedly read-only ID on various kinds of RFID tag you can simply buy a special version from China that allows it (often referred to as gold or magic cards).

There are rumours of cheap Chinese SD cards that don’t follow the official spec and allow you to change to them – I now have large pile of cheap Chinese SD cards on my desk, but unfortunately none of them did allow it. The spec includes a command (CMD26) for writing the CID, but it’s only supposed to work once in the factory when the card is first assigned an ID. All the cards I got seemed to honour that restriction. However, there is probably some way to unlock them If you’ve found this page by looking for help on this topic you’ve probably already seen Bunnie Huang’s SD card hacking presentation, unfortunately I wasn’t able to track down any APPO AX211 based cards, which I thought would be my best bet. In that presentation was mention of vendor commands for a Samsung eMMC used as the built-in storage on an Android phone. I’m not well enough versed on the technology to know quite what the difference between eMMC and SD cards are, aside from the way SD cards are packaged of course – although that might be all there is to it. Reading around they seem work in the same way and appear the same within Linux.

Then I stumbled upon, where Sean Beaupre had managed to unlock a Samsung phone (to developer mode) by reverse engineering some of the eMMC firmware on his device and finding commands that allowed the CID to be unlocked and rewritten. So I started buying Samsung SD cards, hoping for one with the same moviNAND core as the eMMC in their phones. I now also have a stack of Samsung SD cards on my desk, but with the last different one I found I struck gold!

(Collecting Samsung cards is more expensive than cheap Chinese ones and it takes some effort to avoid getting fakes.) The Samsung EVO Plus 32GB MicroSDHC card took the commands from SamDunk and let me change the CID. I have taken the SamDunk code and reworked it a little to make it easier to use for SD cards, but all the credit really needs to go to the original author. To use you simply need a rooted Android device with an SD card slot. Copy the evoplus_cid binary to the device and put it somewhere with a proper Linux file system (not FAT), then apply execute permission to it. Run the tool and point it to the SD card device e.g. Realtek usb wifi adapter driver. /dev/block/mmcblk1 (you almost certainly do not want to use mmcblk0, that is likely to be the built-in storage on your device).
