There's no universal way to roll any Windows Phone device back to 8.0 that's guaranteed to work 100% of the time.
From the Windows Phone Preview for Developers page:
You cannot revert or return to a prior operating system release version after you have updated your phone to a preview update. We will move you forward to a "released state," but we cannot ...
What is Windows Phone equivalent to Google Nexus series?
The closest equivalent to the Nexus series in the Windows Phone market would be the Lumia family, insofar that it's also (as of mid-2014) being produced and supported by the same company that makes the OS - Microsoft. Luckily for you, it also offers the largest selection of devices of any Windows ...
As with other updates, it will be delivered "over the coming months", with the support lifecycle page implying that it becomes a supported release as of 24th June 2014, until (at least) 11th July 2017. The distribution of these incremental updates may be controlled by the mobile operator or the phone manufacturer from which you purchased your phone, so ...
Once the update becomes available, later this year, it will be pushed out as an update to your phone. Your phone automatically looks for updates once a week. If you know it is available, you can force the check in the phone settings.
You currently cannot update it without a Wi-Fi connection. A few possible workarounds:
Share your laptop's internet connection—most laptops should be able to share it via their Wi-Fi adaptor, if not you can always pick up a USB Wi-Fi dongle for a few dollars
You mention that you also have a Lumia 925, setup a Wi-Fi hotspot on one of your phones to share ...
So, after some research, the short answer is: you will get the Denim update when it's available for your device. Being on the Developer Preview programme does not delay or prevent the update.
But if you're running a Dev Preview version of the OS, you may have Denim already but not know it!
Causes of confusion
The previous update, Cyan, was delayed for Dev ...
From this post at Nokia Support forums (emphasis mine):
Phones come in two basic forms:
Country Variant - this is the standard version of the phone that you might buy independently of your operator. Software for these is tested and approved by the local Nokia team in that country to ensure that all local specifications are adhered and country-...
Yes, Windows 10 Mobile is receiving an anniversary update too. According to this article:
Microsoft will release the latest Windows 10 Mobile OS update known
officially as Windows 10 Mobile Anniversary update starting August 2
for supported devices.
The supported devices stated in the article quoted above are essentially those which are running ...
You cannot upgrade a Windows Phone 7.x device to Windows Phone 8. This can be confirmed by a post in the Nokia Forums.
Windows Phone 8 is a generation shift from Windows Phone 7.5 and will
not be available for current devices due to the hardware requirements
for Windows Phone 8. That said, an update will be made available which
will, amongst other ...

Windows 10 Mobile rolling out started on March 17th 2016. Sadly, the Lumia 525 is not in the list for the upgrade. Hopefully it will be in second phase.
Update : May be your Lumia 525 may not recieve the update at all. As Microsoft says,
As Windows 10 delivers significant new innovations, many older devices
are not able to successfully upgrade without ...
Amber is an update exclusive to Nokia devices.
List of changes:
Improved image processing
FM radio support
Glance screen feature
Flip to silence, double tap to wake
Improved storage check, faster HERE map updates
If you are able to do the update via Settings -> Software Update (or something like that) it will not void the warranty, especially not of the manufacture.
Perhaps if you are using the 'Preview for Developers'-application you may want to check it with your telecom provider - which sold you the phone and thus has given you warranty.
If your phone says there's no update and you don't get an error message it means that the update has not yet been enabled for your model-carrier-country combination.
Be aware that updates are rolled out in waves. And even if the update history page tells you there should be an update, from my own experience it can take up to three days until all devices ...
Windows Phone OS (WP8.1 or lower) does not skip updates. The updates have to be installed one by one.
However with Windows 10 mobile it is a different story now. For Windows 10 mobile some updates (not all) are cumulative meaning that the latest update will be installed directly.
If your phone is eligible for the Windows 10 Mobile update and you're waiting for the carrier approval, you can use the Windows Insider app to update your phone and then switch back to the production ring once you have installed Windows 10.
You will get the same version and firmware as with the Upgrade Advisor app.
Be advised that problems during the ...
Yes, installing the developer preview (the only way to get 8.1 at this point in time) will void your warranty. That being said, people don't seem to have major issues so far, and you can probably flash 8.0 back to your phone if something goes wrong (with some effort).
Yes, there are plenty of Windows Phones that are not carrier branded (depending on where you live). You can get those usually at Amazon or similar retailers. With those devices the manufacturer decides when an update is ready to be pushed to the customers.
As a developer you also have the option to install the lastest stable and tested build on your device ...
When the phone is in spinning gears mode with a progress bar, there is NO need for Wi-Fi at all. The phone hasn't even properly booted at that stage, let alone loaded the TCP/IP stack. It is merely, in your case, installing the package that was downloaded prior to the reboot.
If you have waited an hour and a half and the progress bar has not changed, then, ...

Now connect the phone that has been stuck at spinning gears via USB cable (make sure its fully charged) and click continue.
The Lumia 610 was launched as a Windows Phone 7 device. Windows Phone 7 is based on the Windows CE architecture (CE stands for Compact Embedded- this was an operating system that Microsoft deployed to embedded systems such as mobile phones).
Unfortunately, shortly after Windows Phone 7 was launched, Microsoft went down the route of unifying all of it's ...
Whilst updates aren't as frequent as the desktop OS, they do still happen, relatively unencumbered by network or handset manufacturer. Updates are staggered for logistical reasons, so you may see people asking about a particular update a few weeks before it becomes available in your region.
It's worth noting that all the Windows Phones released with v7 (...

Much of the advertising within apps now require this capability. This is done so that tapping on an ad can cause the phone dialer to be launched.
According to the documentation, the only api that uses this capability is the phone dialer task, which still means a user has to press the dial button.
The updated apps probably now provide the ability to detect phone numbers in the content shown in the app and allow you to make a phone call (or get to the dialer) from within the app.
With the Windows Phone being constantly updated, so are the developer tools pertaining to the OS. As the OS is updated, apps can start making use of the newer features ...
