I tried to install with no success, unlocked phone but doesn't allow my to flash new OS on it, I tries CalyxOS & GrapheneOS the same way and I tried run device-flasher.exe on their site but PC doesn't alow me to run it.

It is either your browser, antivirus or firewall that are blocking this installation.

First, try a different browser.

Then turn off/make an exception in your antivirus.

If that doesn't work, check firewall to see if it's being blocked.

In my case, it was the browser and the firewall blocking the download/app.

For anyone wondering... this ROM is amazing. Runs smooth/fast. No bugs that I've experienced. Battery life is good. Not a ton of features, so if that's what you're after you should probably look at Resurrection or something like that.

To anyone security/privacy-conscious looking for a good mix of security and convenience, I think this ROM hits a sweet spot.

I've tried Graphene OS and the Lineage OS with microg patch. Both were great ROMs, but Graphene is way too locked down for my purposes and lineage is a bit too insecure for my nerves.

Try it out! And while you're at it, give the Calyx Institute a look. They have a membership program that has several benefits, including an LTE hotspot with unlimited data.

I installed CalyxOS on my 4a yesterday afternoon and all I can say is "Two thumbs up".

Only issue I have had so far is Signal telling me it can't find google services and the pop-up about establishing a connection (I don't remember the exact wording). I reinstalled Signal and haven't had the pop-up in awhile. Not a deal breaker by any means. I think I have this fixed now.

I'm on Visible Mobile and have had no issues with data, SMS, or calls.

I haven't flashed a phone in 7 or 8 years... The CalyxOS install was simple as pie.

OP updated with March security update. If you are already on January or February's of this ROM, and don't want to wipe your device, you can edit the flash-all.bat file with notepad and remove the -w before the update zip.

    OTA update went flawless (y)

    VoLTE/VoWifi doesn't work for Telekom and O2 in Germany, but no biggie for me.

    I see spotify in the Aorara app store. Its subscription based in the app, not paid through play store
    Yes in that case it will work if you go through Spotify directly, you just couldn't get subscription through Google play and other apps that require payment to download in Google play would not be available in Aurora.
