Soft-Bricked ...

Hi everybody !

I think now i'm in the right place now to post my brick issue question,
so i'm reposting it below.

Here is the thing :

I downloaded some app which was incompatible with my tablet and unfortunately didn't remove it before restarting.
Result ? bricked in endless bootloop until battery runs out .

My main question is :
- can i get it up and running without losing my data ?
or
- can i recover data before reseting it ?

I have lots of questions in relation to this ; but i don't want to make this post any longer now.
Will ask more as the conversation goes along ...

Thanks in advance ! ...
