Lumia 950 stays in firmware update mode

Post by gyurik » Tue Jul 02, 2019 5:13 pm

Hi Folks,

I need help from you! :)

After I tried to unlock my 950 for getting W10 onto it, the Windows Internals (v2.8) after the second phase complained that it cannot connect to the phone. The phones display is red with an arrow form on top of it, such as when the firmware is updated, and doesn't com out of this mode.

I fear that it has been bricked. Anyone could help me getting this nice phone into living again?

Hi Gyurik,

you should try to flash the original Lumia 950 firmware using the thor2.exe from Windows Device Recovery Tool.

Type thor2.exe > help.txt to get a small manual (you must run thor2 in an Administrator Command Line).

thor2 -mode uefiflash -ffufile <Location of your Firmware>. Flash will begin instantly.

Firmware via or WPInternals.

Best regards,
