I recently tested some smartphone's NFC cards, Call the wallet funtion in the smartphone, such as HUAWEI,XIAOMI,SAMSUNG.
smartphone's NFC card can simulate an unencryed mifare card.
if an unencryed mifare card block 0 is: 4E 6D BD C3 5D 08 04 00 01 D5 63 BD FF 77 C0 1D
NFC simulate card block 0 is: 4E 6D BD C3 5D 08 04 00 D2 00 00 01 00 00 00 00
All the same, No matter HUAWEI XIAOMI or SAMSUNG.
simulate card lost manufacturer data.
I looked up some information, modify lost manufacturer data some Android files needs to be modified, It needs ROOT rights!
I'm not sure an app "nfc card emulator" can do this.
my question is : Can I modify lost manufacturer data without using root privileges or using PM3?
Thanks a lot.
