Looks like an faulty eis when you try to read it.

R270 killed the flash 100%.. With the partnumber, we can give you a working flash dump.. ;-)

bad eis or bad key keys mat ,how tool you use for generate the key

0K50E or 3K91D in this case R270 almost everytime erase flash when you try to read EEPROM :( are many threads here on DK about this issue, almost all people have the same problem with this MCU mask :D
when you have eeprom content okey, then is it relative easy, find the right flash version for your EZS part number and reflash MCU, must be then okey :)
