Hi, This rom has also issues, this rom is very slow compared to the previous version v1.5 from 2015.
This is not a good solution...

Admin, please be more precise - whether users should definitively downgrade to version 5 or stay in version 6 and wait for the patch.

Now there is an official firmware and tools

Hmm ... after my painful experience with Android 6, I had downloaded and flashed this version (V1.1_20160429) and similar as reported before, my phone starts switching to German again, every time I go off airplane mode ...
Last time this stopped after ... a couple of days (?) and / or after receiving another over-the-air update.
I speak German so this is not the end of the world but very annoying ... I noticed someone reporting that their phone is switching to Thai (or something similar) and I wonder, if this is connected / related with what country your (2nd?) SIM is from ... but I am just guessing.
Thanks,
Robert
