Crashes all the time on TF300T

I recently updated from the final omnirom build of android 4.4 to the 8/27 omni rom nightly. I updated the gapps package and rooted the tablet as well. Everything would be working fine if the os didn't crash and restart all the time. I updated to today's nightly and that did not help. Is there anything that can be done to fix this?

Unbrickable tf300t

Hello everyone. I am new around here and totally new with android devices. I got my tf300t, installed twrp and flashed to the newest android version. Then my dad suddendly pressed something like restore to the manufactory setting and after that it rebooted and just keep booting with teamwin logo. I can not access twrp recovery mod, it is just in boot loop. I managed to get adb to work, but no fastboot since it does not boot into recovery mode. When I am in adb I can browse the device but the adb reboot bootloader does not work at all. It just hangs there. I can not power off the device because it does not let me, I can not boot into recovery mode with powerbutton and volume down button. After a long power button press it only reboots. I even tried with hard reset button but still the same. Could You please help me somehow? I really need that device for school. Thank you so much.
