An Android phone with NXP PN553 NFC chip was updated from Android 10 to Android 12.
That update resulted that the chip downloaded firmware version 11.21.25.
When rolling back to Android 10, NFC stopped working, because chip firmware mismatches software (libpn553_fw.so of version 11.01.1D) and automatic downloading of older firmware is prohibited.
How to downgrade the firmware on the chip or what other means can be taken to make NFC working on Android 10?
