eried1 Yes unfortunately there is no button combination. (At least I couldn't find one)
I first expected Volume Down + Power to work but that just gets you inside a lenovo specific mode "Lenovo test and reset mode".
I just noticed that NFC does not seem to work for me. Running 20151126 nightly.
Did someone try SIM-Toolkit on latest build?
I just tried it seems to work so far.
Also I just installed the latest opengapps nano build (18 November) works fine (16 November did not) playstore is running and in heavy use ;).
Thank you again ...
HTC Hero running CM 7 nightly.
Its right now in the bin of used phones. I don't really remember using it though it was my daily driver at the time.
