Hi guys

i am looking for information on this huawei OLTs device file, looks lke its responsible for unlocking 3rd_party ONTs..

ont_iofile.iof

does any one have it? or have docs talking about its structure?

[collerok]

also interested in these file structure
but coudnt find it anywhere

BTW its not responsible for thirt party ont unlock. it is responsible for correct OMCI messaging between OLT and OLT

If you are interested in unlocking MA5800 or MA5600. you can pm me. ive got v21 unlocked fw for ma58

and codes to unlock r018 for ma5600

all i found is mention about this file on huaweis forums

Hi thanks, on which version are you using this ont_iofile.iof ? i have heard i need special R22 firmware version then load patch ont_iofile.iof compatible? can you confirm this also? or i can use original huawei R22 firmware version ? I have extracted the original R22 firmware win Binwalk and now analyzing all squash-rootfs more then 10GB unpacked information will try to analyze and disassemble the code to check for more information on the OMCI.. for R017 and R018 i have used the diagnose su commands, but for R019 and R020 and R021 they have changed..
