I bought a zte v7275 tablet
- model number - ZTE V7275
- android version - 4.0.4
- kernel version- 3.0.21-perf-gc8726c4f
- Flash ROM
which is likely to be locked to a single operator (vodafone, but I haven't tried it with vodafone sim card). Any way when I insert a different sim card and navigate to "Mobile network settings" section, I can see all the operator network related configurations are disabled (greyed). I know this particular modle of device is rare in use.
But I would like you to suggest best option I have, following are some of things I came up with
- Install ROM to 4.1 , assuming operator lock, will be flashed
- Install custom build Phone.apk for android 4.0.4 and repalce the existing Phone.apk system app
Further can I know different stratergies can be used to disable the Mobile Network Settings, so I can reverse it.
