I can see no reason why different phones etc. Others have suggested different hardware / firmware revisions might be an issue вЂ“ quite possible but I have no way of knowing (all my Evo Plus cards work, so I canвЂ™t canвЂ™t compare against ones that donвЂ™t). First off, I suspect some people who are struggling have fake cards вЂ“ there are a lot out there and some of them look pretty convincing.

I thought it was worth posting an update with some extra information.

CHANGE SD CARD SERIAL NUMBER HOW TO

My recent post on how to change the CID on a Samsung Evo Plus SD card has generated some interest, but also a number of people who are having problems with it.

evoplus_cid

This can be found in the file like /sys/class/mmc_host/mmc1/mmc1:0001/cid, but the path may vary, and again make sure you are looking at the right card by checking it disappears when you remove the card.Д®voplus_cid-master Samsung Evo Plus CID changer I suggest you make a note of the old CID first, in case you want to set it back later.

If you only need to change the card serial number (part of the CID) you can supply the old CID and the new serial number and the new CID will be calculated for you. Supply the new CID you want to set on the command line. List the /dev/block folder and make sure the device you going to use appears and disappears as you insert and remove the SD card to be sure. dev/block/mmcblk1 (you almost certainly do not want to use mmcblk0, that is likely to be the built-in storage on your device). Run the tool and point it to the SD card device e.g. 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.

To use you simply need a rooted Android device with an SD card slot.

CHANGE SD CARD SERIAL NUMBER CODE

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. 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. So I started buying Samsung SD cards, hoping for one with the same moviNAND core as the eMMC in their phones. 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. Vous devez ГЄtre inscrit et connectГ© sur ce forum pour voir le contenu cachГ©. Reading around they seem work in the same way and appear the same within Linux. IвЂ™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 вЂ“ although that might be all there is to it. In that presentation was mention of vendor commands for a Samsung eMMC used as the built-in storage on an Android phone. If youвЂ™ve found this page by looking for help on this topic youвЂ™ve probably already seen Bunnie HuangвЂ™s SD card hacking presentation, unfortunately I wasnвЂ™t able to track down any APPO AX211 based cards, which I thought would be my best bet. However, there is probably some way to unlock themвЂ¦ All the cards I got seemed to honour that restriction. The spec includes a command (CMD26) for writing the CID, but itвЂ™s only supposed to work once in the factory when the card is first assigned an ID. There are rumours of cheap Chinese SD cards that donвЂ™t follow the official spec and allow you to change to them вЂ“ I now have large pile of cheap Chinese SD cards on my desk, but unfortunately none of them did allow it.

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 is surprisingly little info out there about this, when itвЂ™s easy for other devices. IвЂ™ve spent a while trying to work out how to change the ID on some cards. This can result in you being stuck with a smaller card than youвЂ™d like in a device or not being able to use a backup in case of damage. 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.
