I did some flashing in WPInternals program on my Microsoft Lumia 640 XL Dual SIM (RM-1067 with 0****4 product code). This process ended due to error, phone showed Flash mode (red screen with rounded arrows) and didn't respond. I tried to reboot it pressing 15 seconds power button, but it made it black screen and EDL Mode (Qualcomm HS-USB QDLoader 9008 (COM4) in Task manager) . And from that moment I can't recover it. Same procedure worked with other phone - Lumia 830 (RM-984 with 0*****8 product code) . How to recover it? Output from thor2:

    Hello Franek O,

    Thanks for reaching out to the Microsoft Q&A forum.     

    Based on your description, I understand you're trying to recover a bricked Lumia 640 XL by flashing emergency firmware using WPInternals and Thor2. Unfortunately, the process failed due to a signature verification error, and the device is now stuck in EDL mode, making it unrecoverable through standard flashing tools. 

    Furthermore, Windows Phone 8.1 reached its end of support on July 11, 2017. With mainstream support officially ended, locating relevant official documentation is extremely limited. The support ended quite some time ago, and as a result, there are very few confirmed updates or official guidance available on this topic.
