hi,

is it possible to examine attached dump file,
it is taken from nokia g-010g-r ONT device, which has rtl9601d, G-97CL PCB and 25L95 laser driver.
I want to change the serial number.
enable password generator doesn't work , and ONT> console only reachable at baudrate 9600 ,but nothing can be done in console

thanks.

Hi can you try generate password with this python script?
I don't have this device and when I tried to emulate the firmware from your dump to verify this it didn't work.

import hashlib
# from VOS_CfgParamGetByName("EepEqSerialNumber", a1, 16)
GPON_SN = "ACLCa1b2c3d4"
text = GPON_SN + "-ONTUSER"
# from /usr/lib/libvos.so.0.0.0
charset = "ACDEFGHJKLMNPQRSTUVWXYZ2345679abcdefghijkmnpqrstuvwxyz"
rawdigest = hashlib.sha256(text.encode("utf-8")).digest()
output = []
#  From /bin/Console
#  sprintf(v2, "%s-%s", v1, "ONTUSER");
#  hmac_sha256_pwd(v2, &cli_password, 16);
for i in range(16):
   byte_val = rawdigest[i]
   char_index = byte_val % 0x36
   output.append(charset[char_index])

print("".join(output))

ONT>enable
#ONT>login
User name:ONTUSER
Password:Script output
