Here are some great tips and guides of GM MDI clone serial number update if you need to.
The GM MDIserial number is in the 16mb on board flash memory – the intel chip on the computer sub-board.
You can get u-boot access by making up a serial cable. Signals are available on the 8 pin mini din on the outside of the MDI case. pin 1 goes to PC TX (MDI
RX), pin 2 goes to PC RX (MDI TX). Pin 3 goes to ground. Then when you boot:

of this the update commands don’t work 😭

Failed to read same serial number back from Strataflash
Go to Settings and then click ABOUT. On top you will see Device ID: 10 digit number, which is the Card ID of the SD Card inserted. Unfortunately if you change your SD card it will always show the same number, at least in my case. So try with the right card first. At least you will get the ID of one SD Card. 2 days ago How To Clone Sd Card Serial Number 8,5/10 3889 reviews Is there a way to read the CID of a micro-SD card. Rechargeable battery 600 mAh 8. VXX) for the SD card. Clone SD Card to Smaller SD card. For those of you having problems locating the new files for a china clone Kess v2 running version Open case of Kess v2 and locate SD/TF card. Run the tool and point it to the SD card device e.g. /dev/block/mmcblk1 (you almost certainly do not want to use mmcblk0, that is likely to be the built-in storage on your device). 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.
I think that if we mapped a memory partition at 0x00FE0000 with size 0x00020000
then we would be able to erase that partition and load a new one via ethernet /
tftp. This 128k block would cover both the serial and mac paritions. Both these
partitions have checksums which would need to be figured out and calculated.
What you have been editing is the equivalent of the MDI registry. Once the
serial and mac are changed in flash then a re-flash of the device should put
the new numbers in the registry and they should persist over device firmware
updates. I expect duplicate mac addresses are as relevant as the serial number
duplicates on your lan.
That location is with the entire SD card being read with a hex editor. If you can read the file then look at the end of registry.dat file. The serial number is 16 pairs of hex numbers. Anyone with a clone probably has “4E 2E 4D 95 AA 5D F3 F1 C7 3C 44 B9 97 55 A4 19” which somehow translates to 22129579.

The sdcard is just the /usr/local/ portion of the firmware. The rest is in the
16mb flash.
Be careful, its super easy to brick your MDI Interface with these tools.
Figured it out.
Mount the sdcard parition 1 under linux, and rename telnetd.sh-disabled to
telnet.sh in /bin. While there I also edited the init script and added this
near the start to make the prompt nicer:
Access u-boot (38400 baud, see previous post), and at the prompt type:

boot
The MDI will boot and start a telnet server on its IP and have a new flash
partition configured as /dev/mtd10 called ‘id’. This will align with the erase
block so can be updated. Check in /var/log/messages for the presence of ‘id’
without it being forced readonly.
Telnet in and rip a copy of mtd10 with dd, and send it to an ftp server you
have setup on your lan.
Quote:[root@mdi~]# cd /tmp
[root@mditmp]# dd if=/dev/mtd10 of=mtd10.img

[root@mditmp]# ftpput -u <user> -p <pass>
<ip> mtd10.img mtd10.img
Now load up mtd10.img on your pc in HxD or Hexworkshop. The serial is at
0x10000 with a crc32 checksum of 0x10000->0x17FFB at 17FFC (LSB).
MAC is at 18000 with a crc32 checksum 0x18000->0x1FFFB at 1FFFC.
Update both (just change the last couple of numbers), and use the calculate
checksum feature of the hexeditor to calculate crc32 the sums of of the ranges
and save the new sums in the bin (remember to enter them in LSB format).
Now pull the files back to the mdi, and update flash:

Now reboot the MDI,
and hold down the power button so it goes in to recovery mode. Use MDI manager
to recover the device. Once completed it’ll have the new serial and mac.
I expect that the cloners will find this thread and soon they won’t all have
the same serial anymore. But if you already have one then you can do this
yourself, so long as your careful and make sure everything is going to plan and
makes sense to you as you go.

Flash an SD Card
When you need to save a system to a Raspberry Pi SD card, or similar device, direct copy does not work. You need a tool to flash the operation system image file to an SD card.
balena Etcher is a software tool to flash OS images to SD cards and flash drives.
Etcher is available for Windows, Mac and Linux platforms.

Format an SD Card
To use a new SD card in cameras, phones or other devices, it is better to format it first, otherwise, the SD card may be not supported by the new device, or it does not work in best performance. It is recommended to use the SD Memory Card Formatter to format SD Cards rather than using formatting tools provided with Windows or Mac OS.
SD Memory Card Formatter
Formatting is the process to create a new file system on the disk, memory card, or flash drives.
Common File Systems:
- NTFS: NTFS is the file system that Windows uses by default.
- HFS+: The Hierarchical File System is usually the mainfile system used by macOS.
- APFS: It is an Apple file system developed as a replacement for HFS+, with a focus on flash drives, SSDs, and encryption. It is used in the new iPhone OS.
- FAT32, exFAT: FAT32 and exFAT are the popular and standard file systems used by digital cameras and portable devices.
- EXT 2, 3, & 4: The extended file systems (EXT) are usually used by Linux.

How To Clone Sd Card Serial Number N1996
There are fake SD cards in the market, e.g. you bought a 128 GB SD card but actually, it is a 16 GB Card with faked labels. If you use it in a digital camera, the card of course stores much less photos and videos, it may also cause data loss and your valuable photos may be lost. You may need a tool to test and detect fake or counterfeit SD cards, or perhaps you just want to test an older storage device for errors and problems. H2Testw is a freeware tool designed to test the card capacity, read/write speed of an SD card, or scan and check for errors.

Sometimes, you may need to make a extra copy of an SD Card for backup or other purpose. Win32 Disk Imager is a Windows tool for reading data from an SD card and writing to a image file, also, it can be used to write a image file to a SD card. You may first use it to create a image file from a “Master” SD card, then write the image back to a different SD card to complete the SD card clone.

Important note: flashing, formatting or some SD card cloning and checking tool will wipe the data on the SD completely. So please use those tools carefully.
