I was able to get around FRP without a combination file or ADB access on T280XAR0APH3.
I'll try to list what I did:
Using chrome, search and download:
Get into Gmail:
You should now have access to the google search bar, use it to access the file manager (type my files)
Hope this helps.

- Turn talkback on (Tripple press Home key)

Using chrome, search and download:
- An app launcher apk (note 8 launcher or nova launcher)
- Account manager for android 5.1 apk

Get into Gmail:
- While in chrome, goto a website
- Select any text, choose share and pick Gmail.
- Add a non-google account like outlook.
- Let your email sync.
- Pick any email with text.
- Make a selection, long press and choose web search at the top (grey bar)
You should now have access to the google search bar, use it to access the file manager (type my files)
- Navigate to downloads where all the apk files were downloaded.
- Install the launcher first then open it.
- Now open the file manager again then install the account manager apk and the browser sign-in apk.
- Open the browser sign-in apk and tap the three dots at the top right corner, choose browser sign in.
- Enter a working google account and login.
- Reboot the device and continue with setup until you reach the home screen.
Hope this helps.
