The Z1 compact comes default with kitkat 4.4.2. How do I check the panel_id without root? I just need to find out whether it is a JDI or AUO panel. This can be done easily in 4.3 and now I am getting permission denied when trying to open the /sys/devices/mdss_dsi_panel/panel_id file. Any help would be appreciated. Do I need to downgrade to 4.3 in order to check this and then flash back 4.4.2?

You need to read it using something with root privileges e.g. es file explorer

It is no longer world readable as of KitKat - Sony must be keeping an eye on this forum

If I download the 4.3 firmware from somewhere and flash my phone to 4.3 and check the panel_id file, is the panel_id original to my phone or is it part of the firmware from the source?
