[Android Q&A, Help & Troubleshooting] uylmz:
Hello,

I would like to ask this question in superSU thread but i am not allowed to post there and it redirects me to this general forum section.

Here is the whole process, which makes me think that it is about superSU.

i have nexus 5 with 4.4.4 which is installed by flashing *.img files directly from recovery and only software i used to do this was adb.exe. Later i used superUS's CF-Auto-Root-hammerhead-hammerhead-nexus5.zip file to root. And i didn't set up any google account, just got catlog app from here and start to read it. At first boot of device, there was no error, nothing in catlog file like below and i didn't feel anything about error while using device. But at second reboot and later on "in this time i just granted su rights to catlog when superSU prompted" i saw this fatal errors in log cat file. These errors happen just after i type sim card's password and it happens in seconds, you feel this just a tiny freezing when you want to browse home to app section but later on, i guess this fatal errors caused all random reboots, i have. Do you have any idea? Please let me know, you may see log cat below, thank you.
