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?
