Cannot upgrade app because of signature conflict error

Please bid only if you have experience.

I have an android app and source code.

I installed app on my phone now.

Also Android studio was reinstalled because I have reinstalled operating system.

When I build through new Android studio and to upgrade the app , It appears signature conflict problem.

I cannot reinstall app because I have 900images with remark on this app on my phone.

I must upgrade to keep DB.

Please help me with this.

Thank you
