I'm also stuck on the Indian version totally unable to change back to EUR-EX. Quite unfortunate, I may not have done it if I knew I'd be stuck.Using the above guide Android 11 working fine. But now the phone has some bloatware on it - the Bravo Unicorn App Store. Ive seen you can hide Hotapps & Hotgames in the AppStore settings.
I thought changing the region back EuropeEx might get rid of it - but I get the error 'Connection problem or invalid mmi code', instead of the region screen appearing in the dialer.
Anyway around this?
The dual-wifi works fine - its connects to my 2_4ghz and 5Ghz bands simultaneously, Overall Im more than happy with it.
