BITLOCKER REPAIR TOOL FOR WINDOWS 10 FULL
So, in brief, the steps I went for were (see the forum link above for full instructions). I was first hesitant but decided to give it a try, and it worked! I could modify the steps a bit though since the official device recovery tool already had downloaded the correct image for my phone. The light at the end of the phone reboot loopĪfter some more digging I found references to a Lumia flashing guide at the XDA forums. Why on earth cannot the device recovery tool not just re-flash the entire thing? I don’t know. But a lot of folks had ever found a solution, some even had taken it to several Nokia Care centers and even they weren’t able to fix it. Digging around in the forums I found many people with the same issues, both on previous versions of the OS as well as Win10Mobile. Ok, something to do with reset protection status, definitely sounds BitLocker related. phone: 1.1, ffu:Īt .Thor2Service.CheckResetProtectionStatus(Phone phone, CancellationToken cancellationToken) CheckResetProtectionException: Reading Reset Protection status Failed. Here’s the error message:Īnd examining the log show this error line: 12:04:53Z | 10372 (WindowsDeviceRecoveryTool) | 0x00000019 | WindowsDeviceRecoveryTool.exe | | Information | Flashing failed: Running the recovery tool again also fails, and now I dug more into why it fails. No problem for me though, I have all data and phone settings backed up to OneDrive, so just let me flash a fresh OS and start over. And apparently the key is impossible to obtain. On big Windows, you’re given the option to backup the encryption key (which you should do!) when activating BitLocker, but on mobile it’s a big black box. Hard to read, but the screen says that the key is missing from the TPM (trusted platform module). So I instead went for a reset of the phone from within the About menu. The Windows Device Recovery Tool *should* be able to restore any phone to it’s factory state (and was recently updated to support the Lumia 950/XL etc), but I was out of luck.įirst I tried to run the recovery tool on my phone as-is, the recovery tool downloaded the image but failed even before beginning the flash process.
After getting a Microsoft Band 2 and experiencing some sync issues, I decided to go back to 8.1 and see if that worked better.

I’ve been running Windows 10 Mobile on my Lumia 830 for a while, it’s a major step up from 8.1 and really nice but has some quirks. Want to skip the babble? Jump to the bullet list at the bottom. I hope my adventures in getting my phone back to normal can help someone out there. I just had a nerve wrecking 24h period with a phone that would only boot to a BitLocker recovery screen.
