    so hey guys I went ahead and rooted my phone everything was going fine until right now! Not sure what I did but on bootloader logs says - start up failed your device didn't start up successfully , use software repair assistant on computer...

    I am still able to get into twrp recovery but anything I try ends up with the same result

    "AP fastboot flash mode (secure)
    invalid boot image size!
    failed to validate boot image
    ERROR: failed to pass validation. backup to fastboot
    Fastboot reason: fall-through from normal boot mode"

    please this is a brand new phone and I'm far from rich please tell me this is fixable?????????? thank you

    Did you do a full backup before you rooted? If you did, did you try restoring the system?
