sounds like i have the exact same issues. i bought a glo from walmart yesterday. wife tried setting it up on her mac. it failed always at the login. she gave it to me to setup for her and ive tried everything. almost same testing methodology. setup has been attempted on a mac, 2 pcs with different windows versions, thru 2 routers and tethered thru my cell phone. setup either fails with a network error (i think it actually says oops. haha) or it will loop at the sign in on the computer. ive tried 2 kobo accounts and a facebook account as well. same error on all 4 firmware versions i tried. i also tried formatting the accessible storage under windows... no change. the only way i could access the home page was to inject a user "foo" into the sqlite database but this only allowed offline use. absolutely no way to link an account with this device.
