but she didn't read it. So she applied the update and end up not detecting SIM card. So now she wants to downgrade her phone to 4.2, so how can she do that ? Does she need to unlock bootloader + root in order to downgrade ?
This is her phone. As we live in malaysia, and another friend of her also using the same phone, so she thinks it's the same, so here's the screnshot.
Thank you guys.
Just flash it back to the official version B108 using the SPFT (uncheck preloader when flashing), then IMEI will come back and SIM card will be detected. I believed SummerWind in LYN will also able to assist you.
