with or without conf.txt file on the card.

Beware that some readers might cycle the power multiple times.Ī. Simplest way of doing it is to insert SpoofCID adapter without uSD card and wait for how long consistent blinking(1sec) occurs. Otherwise the process might not complete successfully. NOTE: Make sure the host used for CID programming keeps the power on for at least few seconds. The file will contain CID of the uSD card and CID of your choice(spoofed CID). To confirm successful CID loading insert SpoofCID adapter with the uSD card you just used (or just uSD card) into card reader. It is safe now to remove SpoofCID adapter with uSD card.Ĭ. After successful process the LED will turn back on. During off period adapter will access conf.txt file on uSD card, read CID and write it to internal EEPROM. While blinking carefully insert uSD into SpoofCID adapter without ejecting SpoofCID adapter from reader.ī. In loader mode Host does not have access to uSD card. Insert SpoofCID adapter without uSD inserted(or half way inserted). With prepared uSD card containing only one file(if there will be more files on the card it may take forever) follow the steps:Ī. The card automatically recalculates checksum since linux/android do not read checksum correctly. Last two hex digits are checksum and are ignored. On the card create file named conf.txt with following content:Ĭhange the CID to the one you want. To change CID you need you need empty FAT32 formatted uSD card. Usually after 1-3 seconds depending on the device. LED turns off when successful spoofing occurs. Each SpoofCID adapter has an LED (random color). When host reads CID and the adapter changes it on the fly. You hold your content on uSD and put it inside SpoofCID adapter.

Before soldering TS2DDR2811 IC remove pin C5 ball(internally not connected).

uSD card slot available in aliexpress see picturesģ. Order PCBs using any PCB factory 1mm thickness(ex. If unsure put isolating tape on the capacitors.ġ. It is against standard and causes SpoofCID to skip one clock cycle. Few cards (so far I encountered one) toggle data on rising edge. To change CID you need SD card Reader or device with SD slot that turns on the supply for at least 5 seconds (preferably more). Maybe in future revisions this can be fixed. UHS Hosts are backward compatible by the standard. Similarly if the Device is UHS and the card is High Speed it will still work. If the card is UHS but the device is not there would not be a problem. The problem occurs only when both card and host support UHS. This also should not be a problem at this point. The card is functioning with adapter but no spoofing possible. UHS – Ultra High Speed is not supported – due to 1.8V signaling. This issue should not be a problem since almost all commercial applications of SD cards use SDIO(which is supported).Ģ. The card is functioning but spoofing is not working.

It allows to use any user microSD card to act as regular size SD card with user defined card ID. SpoofCID is an microSD to SD adapter with builtin functionality do swap Card Identification Number.
