Sorry but my phone patch unlocked has all padlock open. I believe that only method to detect the patch unlock is the "identifiy" funtion of Setool2 lite.
Or else if i go to info software into hidden menu the phone show me:
EROM: R3A022 prgCXC1250487_EROM_DB2020_THELMA_MIWA_RIKO_FOTA_SI MLOCK_FLAFLA_SIBLEY_SEMCUSB
It maybe another way to detect a patch unlock??
