I followed instructions in this post: http://www.xperiablog.net/2017/06/28/android-7-1-1-nougat-xperia-z5-z4-tablet-z3-plus-32-4-a-0-160/ Flashed firmware Xperia Z5 Compact_E5823_32.4.A.1.54_UK_Generic 7.1.1 Afterwards no SIM will work. I find that in About phone, Baseband and IMEI says 'unknown'. Cannot restore as no backup taken - my wrong! How to fix this issue? Thx
