[HTC U11  Guides, News, & Discussion] Peak81:
Rookie question.

How do I install the zip file?

Thanks I advance!
[HTC U11  Guides, News, & Discussion] metal_ghost:
Restart device.

Press Power button and Volume down button, keep them until you see download mode.

Use the Volume rocker to navigate to the menu entry Reboot to bootloader and press Power button to confirm this action.

Use the Volume rocker to navigate to the menu entry Reboot to Recovery and press Power button to confirm this action. Your device will now reboot to recovery mode.

When recovery starts, you will see a red triangle with an exclamation mark within. Don’t worry nothing bad happened, this is just the entry screen of your stock recovery.

Wait for a short while and press Volume-Up button with Power button. This combination allows you to enter the Recovery menu.

Use the Volume rocker to navigate to apply from phone storage option and press Power button to confirm.

Now you can choose your OTA package.

After reboot you will get message that you successfully updated your device.

Happy flashing...

I got the update too. Unfortunately, I don't want think it's the update we've been waiting for. This one is update 1.16.617.6, and the only thing listed was "system enhancements." The update the Taiwanese model got a couple weeks ago was 1.16.709.5, and the updated features list was longer, including things like "camera improvements." As far as I can tell, the only difference in this update is the security patch. The camera shutter lag is still the same as before on my unit.

I don't know what you guys are talking about. 1.16.617.6 is blazing fast with the camera shutter speed. I took a picture while it was still doing post-update processing and it snapped immediately. HDR took a few seconds to process but the shutter is instant.

I dont think they can go meddling the original state on these devices they are just making them problems after half a year with a "phone" that is really a computer priced computer device. I used to think it could be done. But that was around the time of android L and M.

There has ta be a way to get just the security updates but keep original phone in working condition.
[HTC U11  Guides, News, & Discussion] 5m4r7ph0n36uru:
Can't complain about camera. Even with latest update focusing works flawless on my end.

Which gallery are you using? If still on an HTC Gallery port, this is due to missing development of the App by HTC. Honestly if that's the case time to find a new App. No problems here with Google Fotos and Camera Roll as a gallery App.

Oreo has new way in how some notifications work. There's one giving a feedback about Apps that wake an e.g. scan storage for new MP3. Those will disappear right away as soon as the App stops.

Battery usage is also better on my end.

But to get back to Nougat, go S-OFF, flash Nougat RUU right away. Reboot to go back S-ON, and be happy. But all you data will be erased, so you'd have to start from scratch.

And pay 25$, so no real solution unfortunately without reinvesting even more money in a device which is already pretty expensive...is there not another way? Hardware, apps and settings are different on every individual device. My Oreo update is making me think about to sell this device, because performance is noticeably worse than before. I hope HTC solves these problems, because I always loved HTC phones.

Ps. There is a thread about the newly introduced bugs and flaws in oreo, but HTC announced that the update for Europe does take so long just to NOT introduce them to our deviced as well, which, by now, was a plain lie and that disappoints me.
[HTC U11  Guides, News, & Discussion] Azathoth6:
solve it thanks
[HTC U11  Guides, News, & Discussion] 5m4r7ph0n36uru:
Read this thread as well and can't agree with some of the statements at all. First of there are many features introduced with Android Oreo by Google. Those are no flaws and in addition nothing we could blame HTC for in the first place. Seems a lot of users are always forgetting about that fact. There are flaws in Oreo as such, at least if I read it correctly on the Pixel forums.

In addition there are devices of some users who tinkered really a lot prior to the Oreo update, causing problems now. Well for those I got to say: they should have known that it might have effects, if not done properly. All who've always been full stock might have some problems here and there. But it seems those devices are seldom and HTC has a warranty, so why not make use of it!?

Device variants have to be different in some ways. E.g. in the US where devices git to support either CDMA or GSM networks which work completely different.
