Windows 10 Mobile build 10581 bricked phone (bootloop)p

I own a Nokia Lumia 920. I was on the last build that didn't require flashing back to 8.1 to upgrade. I got build 10581 to download. It tried to do the pre-install stuff ("Preparing to install" in settings app). It failed the first time but worked after redownload. Once I hit restart, it rebooted into the screen with the rotating gears. At this point, the progressbar filled up a little, then a giant ":-(" filled my screen. Then the phone rebooted (it was plugged in). It would repeat this cycle until I unplugged it.

What I have tried:
- LDR/WPRT won't recognize the device
- Flash mode (vol+ on boot) won't do anything
- I can't get the "!" to show up by holding down Vol- on boot
- Vol- + Power while gears are spinning restarts the phone, no change

Thanks for your help!

UPDATE: I did get WDRT to recognize the device and download firmware. But when it tries to install it, the NOKIA logo on my phones screen gets really big. Then WDRT reports that the install failed and the phone restarts.

You just have to keep trying to re-flash it.

Search for "dead flashing" using Nokia Product Support Tool. Safest way to flash a firmware

I am having the exact same issue, and am not having any luck getting my phone out of the loop, or recognized by WDRT.

I should mention that I can get it out of the loop onto the lightning bolt and settings icon, but still can't get WDRT to recognize it.

Does anyone have any suggestions?

update let your battery die, and when you start the WDRT plug in your phone and it will be on the nokia screen long enough to be read then your can restore to win 8.1 and yes my microsoft account is working again

Plug in your phone pressing the volume UP button you will get a lightning logo or just a Nokia logo the use the Windows Device Recovery Tool and select my device was not detected and it will then find it and start from scratch.
