I am thinking of flashing my Micromax a35 with stock Android 4.1.2 Rom of galaxy S3. I know it is not a custom rom but since it is not of my device can be considered as a custom rom rather than stock for my device. So regarding this my questions are as follows 1.) Is this a good Idea? 2.) My phone has no gps, so gps related app or os components should crash or will they take the whole os down with them? 3.) Should I install Cyanogen mod (Galaxy Vibrant) instead of this? 4.) Can someone give me a super detailed copy of instructions regarding rom flashing and clockwork mod with its working and installation? 5.) Is there a way to remove gps from the settings of ICS rom and from the notification screen as well? in other words can we remove gps functionality from it altogether? Thank you in advance and I am sorry if any of the above questions sound stupid. I have no idea regarding rom flashing(have never done it before), though I am a developer on android and wanted to switch to ICS. EDIT: No custom rom is available for my device and that is why I had to choose the galaxy s3 rom as an option.
