How to setup samsung galaxy j7 mobile after factory reset has been made and i have forgotten my google id

We don't e-mail answers but hopefully, you'll get a mail telling you your thread has a response.

Tell your friend to go into G-Mail on a PC and type any word in the password at login time. She'll be told the password is wrong and an offer to go through the Forgot Password process.

She should be the only person who can answer the security questions she set when she created her account.
