Default [Q] is there a way to access system files through recovery/bootloader?

whenever i turn my phone, i get an error that says the com.android.sdksetup application failed or something like that and when forced to close, it would just show up again.

as a result, i'm stuck in that infinite loop, i can only access recovery (3e) and the bootloader. I've tried a factory reset but that only erases user data. Since it runs on 3e recovery, I get signature verification errors when trying to flash to a different rom. I was wondering if there's any way I can access the system files through any of these two modes? the phone is the Gsmart rio r1
