  3. Bro. Thank you for this tutorial. I got my S860 system crashed last month.

    I use the latest SP Flashtool (, got downloaded from the official site ) on Win 10 and it's work well. I did not do the last step (no 9) because it's already in the proper build number for the firmware at my phone.

    Keep up the good work and kind regards from Jogjakarta.
