I was flashing my Blackview A7 with SP Flash Tool, but I made two mistakes:
1st. - At the beginning I choose "Format All+Download" and at the end IMEI on the phone was deleted
2nd. - I choose stock rom A7-Blackview-V1.4-20171020
Now flashing this phone with any ROM is IMPOSSIBLE!!!
Writing a new IMEI with SN writing tool - IMPOSSIBLE too!
Please, can someone help me?
