  1. Hi. When a phone has been rooted, the software in the phone is changed, which can lead to varying results. Sometimes it is necessary to temporarily revert the phone back to the original default software to unlock the phone.

  2. After dialing *#0011# I get a different result — “ServiceMode — No Service — IMEI CERTI – NA”
    Perhaps you have to put in a certain SIM card in for this to work? In my case, it still has the Sprint SIM in it, but the service has been terminated. Do I need to put a new carrier’s SIM in in order to unlock?

  3. i use samsung vibrant sgh t959. i have gone through the unlocking procedure given but nthing shows when i select the network lock i only see ‘PRESS BACK KEY command is 1867. how can you help
