Broken screen and home button being fixed or dead

Your iPad mini3 is obsolete. Apple no longer offers support or repair services for this and similar models of iPad.

Your only potential option to revive your iPad mini3 would be to use a third-party repair shop - who would either use parts scavenged from other broken iPads of the same model, or will use third party parts. In either case, you must understand that (a) all locally stored data will be lost, and (b) the cost of repairing an obsolete iPad is unlikely to be an economic proposition.

You would be well advised to reconsider revival of your broken iPad - and instead spend your money in replacing the iPad with a much newer or current model iPad that supports iPadOS 26 and current Apps.

If you have an existing iCloud or iTunes backup of your broken iPad, this can be restored to the replacement iPad. Any files synchronised with iCloud will remain directly accessible. As is, any locally stored data that is not included within a pre-existing backup is almost certainly irretrievably lost.

it's old back 2014

doubt it would be worth is to fix it

if you have problems connecting it to your computer because that has issues then you can likely get the photos from using another computer than your own

apps are not tied to your old ipad they are tied to your appleID so if you use that on a new ios device then you can get them again.
