If it doesn't work you should first flash again with "format all + download", then use the SN_Write_Tool.

Hi phil, my bv6000 cant detect simcard and sdcard since i ota upgrade to 7. I tried flashing many rom but still my sim card and sdcard is not detected. Factory reset, clear mmc from factory mode doesnt help.. is there any way my bv 6000 can detect simcard and sdcard again, if not it became an expensive brick.. i cant send it to the seller because postal service here refuse package with battery ini it, and seller refuse if i send bv6000 without battery. my life suck now because of this phone.
