I have a VMG3625-T50B running an ISP-dedicated firmware version (V550ABTL0b2r). I managed to get the supervisor password yet I can't enable open an SSH port because my SP disabled that option.
I've been doing some research and found this blog that on getting a root access on a similar modem (the differences are merely zero). In the blog, Thomas describes how he gets root access by modifying the Backup_Restore JSON file. Unfortunately, mine is openssl-encrypted. The first line of the file is:
I've read somewhere on GitHub that I can decrypt the file using the supervisor password and I tried every password generated by boginw's keygen but I had no luck. (The password that works for my modem is generated using zcfgBeCommonGenKeyBySerialNumMethod3).
I need to enable SSH so that I can debrand that modem and flash the global firmware, but that won't happen until I disable 'firmware ID check' aka fwidcheck using zycli.
Does anyone have any idea how to enable SSH on that modem by modifying the Backup_Restore file? or any other way really
