Hello everyone,
I've update my lumia 625 to Windows 10 build 10130 this morning.
However my phone keep restart every 3 minutes or whenever I try to open any app except setting.
So I try to hard reset it, it does not work, my phone can't hard reset, all it do is a normal restart, nothing change.
Then I tried to use Windows Phone Recovery Tools, does not work either, my phone only show the Nokia logo for a while and then nothing happen, WPRT said recovery fail.
Then I tried Nokia Care Suite to flash my rom. It return an error code: FA_ERR_VERIFY_FAIL: 0xFA00000D

So, in general, I can't hard reset my phone, can't use the recovery tool, can't flash rom, and cannot use my phone since it restart every 3 minutes.....
What should I do now? Somebody please help me.... :(

My WPRT kept failing. I restarted my PC (since I had just installed WPRT prior) and it worked first time after reboot.
Give that a shot if you haven't already!

How is it not working? When you try the hard reset, does the hard reset not attempt to start? Or does it start and fail out somewhere in the middle? Give us more information and it'll help others figure out your problem.

It does not start, not at all, when I hard reset my phone, it just do a normal restart, nothing happen.... :(

So what happens when you in into settings and hit reset phone and get prompt and stuff?

It DOES NOT reset? This is what you are saying?

It does a restart, but not reset anything at all.

Doing a hard reset on your phone will only take you back to the factory settings on the same version of the software that is already on the phone. For instance, if you have the new build, 10136 on your phone and do a reset, it will reset you to the same version of the software. The only way to get back to WP 8.1 is to use the Nokia Recovery Tool. Can you explain how that isn't working?

After the update I reset my 1520, but the WPRT doesn't work: it finds my phone, then I press on it and then infinite loading starts. I want 8.1 badly :C.

When I use Nokia Recovery Tool, it restart my phone and the red screen with a nokia logo and a process bar show up for a second then the phone restart again, nothing happenned. The tool say the process has fail. Nothing more.

Try a different computer, possibly with W8.1, nothing to lose there.

I did my roll back on my 925 using my Dell venue 8 Pro, After the successful roll back, I would love to free up the 1.5Gig storage space firmware is taking. Anyone knows where to find and delete this? Disk clean up doesn't locate... Please advise. Thanks

For those having difficulty with rolling back to WP8.1... This new version of the W10M TP has Reset Protection. Reset Protection will not allow it to be rolled back if it is enabled. If you did a hard reset after upgrading, then Reset Protection was turned on by default. You will need to go into Find My Phone and turn OFF Reset Protection in order to roll back using Windows Phone Recovery Tool.

That's my understanding of it anyway, from what I've read about the Reset Protection.

Did that on my 521, which is on build 10080, it does not work.

[rhapdog]

Wow. Didn't work.

That kind of stinks. Did you have Reset Protection on the 521 before you entered the W10TP?

Or have we now completely lost the ability to do a roll back? Is there any official word on rolling back from Microsoft at this point?

I did that too, not work either. I also check my Reset Protection Status from my Microsoft Account, it said "off". Still the same, can't reset, flash, recevery.. etc.

[rhapdog]

Is there anyone that's been successful rolling back yet?

[Harrie-S]

Is there anyone that's been successful rolling back yet?

Yes I did on my 920 and 930 with no problems.
And I saw in a few posts that others could rolled back after installing 10136.

i am using lumia 520 and I have the same issue. I cannot reset, recovery and flash. etc..

[rhapdog]

I was not only "unsuccessful" rolling back, but the Windows Phone Recovery Tool threw an error at 24% during the flash, and my Lumia 635 was bricked. It took 4 days before I finally found out that only the Lumia Software Recovery Tool could handle doing a dead flash to not only bring it back to life, but to bring it back to the original 8.1 that the phone came out of the box with.

Do a web search and find Lumia Software Recovery Tool and use that for rolling back. I ended up downloading version 5.05, which required me to do an update to 5.08 before I could use it. Worked like a charm. Wish I would have started with it.
