Hello,

I am trying to flash my SE W810 using XS++. Phone connects by connecting the usb cable, holding C button and then pressing to power button.
But when i start flashing the main firmware, process stops at this error



21:42:47| 344 flashblocks
21:42:47| Binary acknowledge failed with: 1521:42:47| Command: Error 0x15
21:42:47| Failed sending flashblock 1. Returnvalue 0xFFFF250B
21:42:47| Finishing flash



can someone please solve this issue?
