I decided to start fresh and used WP Recovery Tool to go back to 8.1. Since then trying to update to 10149 has been giving me the below error. I've tried resetting a few times but still same problem. According to Windows phone 10 update 10149 won't install error code 0x80070020 - Microsoft Community I am not the only one. Anyone else encountered this?

No you are not the only one. The other personnel in that thread also experienced this.

That's what I said. Maybe if you have nothing useful to add to the thread you shouldn't say anything? Keeps threads clean and useful. Thanks.

[Asik15]

Can someone tell the exact size of this update????

Says the guy who started a thread with a fresh install of 8.1 but can't upgrade to the latest technical preview software when the answer is obvious.

Ya... Good job buddy.. Lol.

****, if you're so clever and the answer is so obvious to you why don't you enlighten us? I hope your name is ****, because you sure sound like one. ​

Thanks. I tried this a few times and still it didn't work. I have almost 25gb of free space on phone so I doubt phone storage is an issue. I used WPRT to install 8.1 then setup my phone without restoring anything, downloaded Windows Insider and selected Insider Fast. Phone downloads the update properly and then give me the option to Install. It starts installing and then I get :-( and it reboots back to 8.1.

I am facing the same problem but with a different error
0x80070057 ..

[naeem151287]

This is what I did -

1. Flashed Indian ROM (from HK)
2. Didn't restore anything.
3. Deleted all 3rd party apps.
4. Installed Preview for Developers.
5. Completed all updates.
6. Installed Windows Insider and selected Fast Ring.
7. Downloaded build 10049.
8. When installation started (gears screen), put the phone in the refrigerator. It got to 100% after about 30 minutes and got stuck. Removed SD card and installation completed successfully!

[Ivan05il]

I'll have to try that thing with the refrigerator :D It was turning the wheels for more than 30 minutes and when rebooting it turned itself off. Then when turned on it turned the wheels a bit more and turned itself off again each time I tried. I don't know why MS does not make the install image available via WPRT, with a special option to check for previews instead of WP8.1. An installation would be a matter of seconds instead of this torture.

[Mattman86]

4. Installed Preview for Developers.
5. Completed all updates.

Why?

[naeem151287]

Why?

Someone on the forum suggest I try it, since he/she had done so and it was successful. I don't know if it's really necessary but the steps I followed lead to a Windows 10 Mobile 10049 build that's running fantastically on my Lumia 1520.

Makes sense. Are you having any issues with heat so far?

None at all. All the apps have installed correctly and it seems very stable and fluid.

What do u mean by 'Delete the page'

When the phone displays an empty battery sign while updating it's because it overheated, not because the battery is empty. So putting the phone into a fridge is actually a good idea :D It happened to me yesterday and then I had to rollback, because nothing else seemed to help. If the phone were in the refrigerator it might have worked. I am going to try it today, just for the fun of it.

ETA: I hate to bring this up, but I was updating my brother's Note 4 to Lollipop and it went very quickly and without any glitch or overheating while updating WP is always one big PITA.

[Ekamek]

Remember, this is not a final OS as in Android 5.x or even 4.x. Reinstalling WP8.1 doesn't cause the phone to over heat and everyone accepted the risk of installing a beta software. As much as I have reservations from the beginning and putting the phone in the refrigerator too, it's a precaution so the battery doesn't deplete much faster because of the heat. If the final OS continues to make phones overheat, then compare WP10 to Android. Until then, we are all taking the risk that is clearly stated.

[Ivan05il]

It happened after rollback to 8.1 too, when installing some updates after RTM was flashed and yes I let the phone cool down before proceeding. Luckily I was able to break a reboot loop, turn off the phone, let it cool down and turn it on again and finish the 8.1 update.

[Ekamek]

I have a 1520 too and these are the steps I took:

1. WPRT to WP8.1
2. Use default setting throughout
3. Install updates for pre-installed apps (minus carrier apps that I removed first before updating)
4. Phone auto download update for WP8.1 but I didn't install it until all apps were updated/removed
5. Restarted the phone to complete Extra info, motion, network+ settings
6. Download Windows Insider (can be done after installing WP8.1 update)
7. Installed WP8.1 update
8. Accessed and Configured phone for Insider program/rebooted
9. Downloaded WP10 (OS Version 10.0.12648.133) build 10149
10. Installed new preview OS and have been using it since then on daily driver.

Note: It's a beta OS and yes, there are bugs but it works as design at this stage.

So putting the phone into the fridge actually worked. This time I removed the SD card, because somebody wrote it helped, too. So it was for about 2 minutes in the freezer and for the rest in the fridge, about 20-30 minutes, if anybody is interested :p The screen went black with only the buttons on and then I realised it's because of the missing migration screen, I use another app to manage the lock screen and because it was not installed yet, the screen was black. It actually works nice without a hard reset, too. I may do this later if I have problems. It's all a bit slow, loading, starting, if something pinned to the start screen crashes, it helps to unpin it and pin it back. One of my frequently used apps still does not work, so I'll keep it for a week, check if the hard reset helps and if not, go back. But I like what I see.

I had the build prior to 10149, I was able to install the 10149 with no problems, however several apps that
come with the phone won't open (Camera, People, and Photo) for example. The message that appears:
Uninstall and try buying the app, then try it again. I tried with photo app and still get the same error. I'm wondering when the next build will be available.
