hoe do you replace mother board, with out loosing information on phone

@ukaperson, karen, ZTE N817 Smartphone mother board dead. Have you had the phone already looked at by a good cell phone repair shop, if not you should have a good local shop have a look, diagnose and estimate the repair if they say it can be done with out loosing all your information((make that clear to them)). If the info. is really important and it is on internal memory of the phone, you will want to contact a good professional data recovery service. You could maybe even ask your carrier who they recommend or use. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
