i was even hoping to find a tutorial of how its done manually. hope someone would give us a tip about this. that's why i am hoping to have an app to back up the firmware before even reflashing it to unbranded but i don't know where to look for these apps. i think its in the firmware customization. i encountered it also from a huwaei e151u-1 isp suncellular in the philippines its openline when you insert providers sim but if u open it up its not or changed sim. Hi Dear Jim.Mahoney, after i use this unlocker I got SIM Status: unloked, But when I try to change other Operator SIM, it's said that invalid SIM and in that Tool said SIM Status: Locked :(, could you help me, please? so we could develop more apps that gives more functionalities. and hopefully somebody could give tips on how it is done manually with out the apps. do you know an app that supports huwaei e153u-1, e153u-2, e153u-3, e151u-1, e152u-1 and ZTE MF612 if there is and its tested pls advice me the link to it. So there is no need to manually enter codes. This software can direct unlock Huawei models, Orange Vegas / T-Mobile Vairy Touch / Vodafone Indie SFR 341 / SFR 342 / SFR 343 / SFR Messenger Edition 251
