Default [Q] Backup for Evolveo Xtraphone 5.4

Hi.
Have anyone backup for my phone?

Problem:
I tried app (LCD Density) from play google and changed dpi. I reboot my phone and logo stayed upside down. I also tried change dpi (and remove) in system/build.prop, but without success. Have anyone idea (without re/install rom) ?

I have only root without recovery mod.

Thanks for every comments and excuse me for my english.
