Lots of users who got Huawei G7-L03 from phone operators left behind in updates, as these operators are not releasing any updates for this phone. a user from Chile contacted me for update as his phone was locked to Movistar. we did experiment and successfully debranded and upgraded his phone without any problem. procedure is as following.
