Honor 6 missing OTA upgrade to android 6

Is this because the OTA update isn't out yet, or because my phone is not compatible?

Honor 6 user till few months ago. Honor 6 upgrades are a terrible mess:

• They are released region specific, example, India, Malaysia, Russia with the Chinese one completely different.




• Performance / Stability varies from region to region




• AFAIK except for Chinese, they're wasn't an OTA to start with. For Indian market the upgrade was available on their Facebook and then on their website and about two months later, OTA was released and that too had teething problems




• Company preferred mode of informing users is on their Facebook page , so you would need to check out there




• Downgrading is not straightforward and you have to risk that

So, coming to your specific question, it looks like OTA had not been released .

Is it safe to upgrade using the downloadable firmware? The procedure seems easy enough

You can use update file but make sure you research user feedback because of downgrade issues. With the Indian version there were issues with battery life, missing functionalities, and random bootloops

Will such an upgrade reset my phone, or will it keep the data?

If it is not OTA, you lose data
