What you have is the Windows Mobile operating system. The highest stable version Windows Mobile can be upgraded to is 6.5.3. Windows Phone is a new mobile operating system which was created to replace Windows Mobile. It cannot be upgraded to from a Windows Mobile device. You will need a new device that runs the Windows Phone OS.
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 ...
Microsoft announced an update will be available for current Windows Phones. The update will be named Windows Phone 7.8. There will be no way to fully update your device to Windows Phone 8.
Also, the update will be sent out using the Over the Air technology.

It is not physically possible to upgrade your device to WP7. It doesnt have enough RAM (128MB), Screen resolution (240 x 320), or processor speed(400 MHz) to run the OS.
Even after they've spent a year optimizing the OS, You need at least 256MB, 480x800px, and 800MHz for Windows Phone.

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 ...
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.
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 ...
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 ...
Unfortunately the current crop of Windows Phones cannot handle the NT Kernel which Windows Phone 8 is built on. This would require new processors and processing languages.
This article from Mashable has details on it.
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 ...
The solution is to do a complete reset of your phone:

Press these buttons one at a time in this order: Volume Up, Volume Down, Power, Volume Down

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 ...

Flip to silence, double tap to wake
Improved storage check, faster HERE map updates
You simply cannot on the TyTN II; if you want to use any version of Windows Phone from 7 and above, you need to buy different hardware.
And the same goes for an upgrade from Windows Phone 7.0, 7.5 or 7.8 to a version 8.x (and above): needs different hardware because of kernel changes.
Unless you have a special phone, it wasn't the update to 7.8. Windows Phone 7.8 for Nokia devices will become available in December. So, you've probably just installed the latest security/bug fix package.
There are rumors that it will launch this week, but the phone manufacturers doesn't need to push those updates immediately, some might even decide to roll ...
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, ...
I faced the same issue, my phone was kind of dead for three days, but later on I managed to escape the situation without loosing any data.Steps i followed

I've got the same problem, but I found this and now is fixed. Hope it helps.
Download and install latest NokiaSoftwareUpdaterForRetail
Run NSU and this window will pop up. Then click "My device does not boot up"
Now connect the phone that has been stuck at spinning gears via USB cable (make sure its fully charged) and click continue.
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 (...
