Now I would like to try to do the same thing by sending the necessary commands to the uSD instead of using evoplus_cid.Īfter initializing the uSD successfully, I am trying sending these commands that I found somewhere here in between the messages:Ĭmd17 0x00 (confirm Smart Report after reading Sector 1 at Address 0)Ĭmd26 0x00 0xFE (WRITE_CID+single block write start TOKEN+16byte NEW CID) I have a uSD of which with evoplus_cid I can rewrite its CID. I’ve also fixed a bug causing the displayed CID to include some extra ‘FF’s. Although, I’ve got a laptop that always displays 00 for the checksum when showing the CID, so I wonder now if his cards really did need that! I’ve fixed a bug when compiling on 64bit Linux that could prevent the CID being written. This was requested by a user for cards that apparently always had a checksum of 00.

If you supply a full 32 digit CID (and don’t apply a serial number modifier) it will be written as is without recalculation of the checksum. I’ve made a couple of updates to evoplus_cid. The tablet is running CyanogenMod 13 unofficial from here. I have used evoplus_cid on a Samsung Galaxy Tab 2 (10 inch, wifi model, p5110). I also cannot guarantee that you’ll get working or even genuine cards, but I have purchased on two occasions from this seller and the cards have been genuine and worked with evoplus_cid. I am not affiliated with the seller and get no referral commission from this link. Purchased from this listing on AliExpress. I doubt many of the fakes have properly set Samsung CIDs so hopefully this is an easy way to tell. Last is the checksum (a1) which will be different on your card. I also have March 2016 (0103) cards that work fine. The next 8 hex characters (98625deb) are the SD card serial number, yours will be different! The manufacturing date is next (0102, or 0 10 2), where the first digit is ignored, the next pair is the year in hex since 2000 and the last digit is the month in hex. The manufacturer ID should be 1b, followed by an application/OEM ID of 534d. Card CID – check it and compare to working ones.Mine are made in the Philippines but this is probably not the only place so don’t get hung up on this. Text on the back is printed so it is read with the card contacts end pointing upward. Correct font, especially for the capacity digits, some fakes don’t use the correct slim font. Slight bevel on the contact side, to help insertion.

Smooth back, not lumpy showing circuit parts beneath the surface.

The card – lots of subtle details to check.

All of mine have, but oddly enough when I tried to check one on the Samsung China website I didn’t get anywhere with the verification code, the site was in Chinese though so I might have been doing something wrong. The real ones have them (recent ones at least), fakes might but probably don’t.

Hologram, with scratch-to-reveal verification code.

Look up the UPC from the barcode on the back and make sure that matches the product and size of your card. The correct size should also be printed on the packet. I had one fake that incorrectly stated a 32gb card was SDXC on the pack instead of SDHC, the card itself had SDHC printed on it.

Packaging info – the product information should be correct and match the card.

The gloss overlay over the printed areas should align with the printing below them, if it’s offset that’s a bad sign.

Packaging quality – the image should be well printed, in high resolution and good bit depth on the colours (some fakes looks like they’ve been converted down to 256 colours).

These are very common and if you google for fake Samsung cards you’ll find lots of info on how to spot them. would give different results – as long as it’s a proper SD controller (not a USB mass storage adapter) then sending the command should work just fine. I can see no reason why different phones etc.

Others have suggested different hardware / firmware revisions might be an issue – quite possible but I have no way of knowing (all my Evo Plus cards work, so I can’t can’t compare against ones that don’t). First off, I suspect some people who are struggling have fake cards – there are a lot out there and some of them look pretty convincing.
