NFC extended length broken in 4.2.2 update

Under 4.1.2 extended length APDU support over NFC worked like a charm. Now with 4.2.2 "Transceive errors" occur everytime an extended length APDU (longer than 261 Bytes) is to be transferred. Seems someone put in old drivers (libpn544_fw.so) and/or old Nfc.apk.

 

This renders the phone finally unusable when you're using intelligent RFID chips for authentication.

 

Bad update.

Re: NFC extended length broken in 4.2.2 update

Found it. You guys put the wrong (old/broken) libnfc.so into the Android 4.2.2 update. Taking the old one and exchangig that makes the phone working again. BTW: The Xperia M can be modified the same way. My SP, Z and Z1 have to small antennas to give useful test results with our tags.
