Old firmware for VMG3625-T50B (I need version V5.50(ABPM.6)b5_Q0)

Haschman

Hi, I have Zyxel VMG3625-T50B and I want to update it to newest firmware. However when I did it last time some T-Mobile wasn't happy about it and forced me to replace whole modem for new one. I still want to update the new one but in case that they will discover it I need the option to downgrade it again. Is there some option to download old version of firmware? I need this version: V5.50(ABPM.6)b5_Q0

Thanks!

check with your ISP for fw version. if it is not on your device, it means it cannot use with your ISP settings, which is why they have not let you use differet fw version.
