  • No signal after successful unlocking ZTE MF90 Bolt

    Today I unlocked my ZTE MF90 Bolt using DC-unlocker client software V1.00.1118. The status is unlock fine but now there is no signal (red). Before unlocking it got 3-4 bar blue signal. Change to non-Bolt operator SIM card also the same no signal even tough the SIM is now valid. Have powered off on several times, removed batteries and reset...still no signal.
    Pls advice how to fix this. Read about firmware B05 and B07 but confuses one suggests to upgrade B05 to B07, other downgrade from B07 to B05?

    If you have checked settings and with operator of device, then you should update device to latest firmware of the device, and then perform unlock for it again, before unlocking it again check with original bolt sim card if device works.

      I've checked with Bolt operator and they told me to bring the device to their repair center. I will try to update with the official B07 firmware before bring in for repair though.
      Anyway I consider the unlock fails, pls tell me how to reclaim back those 7 credits to my dc-unlocker account?

          Never mind.
          Before I updated the firmware I run DC-unlocker again to check the existing firmware version. This time it got hung but then to my surprise I notice the signal is now blue. Weird, but i get the signal now so I cancel the plan to update firmware and/or bring in for repair.
