Reset admin access

 need help with my XB7 Admin Tool credentials. I forgot the Admin Tool password and performed a factory reset, but the reset did not restore access. I have tried the sticker password, “password,” and the current Wi-Fi password with username admin, and none work. Admin Tool access is enabled in the Xfinity app, but the app does not give me an option to create a new Admin Tool password. I need access to 10.0.0.1 so I can put the XB7 into Bridge Mode for my TP-Link Deco BE63 system. Please reset/reprovision the Admin Tool credentials or replace the gateway if necessary.
