I don't know what actually happened to my phone; since last week, I changed my mtn sim to a glo sim and then, I inserted back my sim and ever since then, my phone has not been detecting sim both on Slot 1 and Slot 2.
It is kind of strange that even if I insert the default mtn sim into slot 1, it still does not detect it.
a. I have unlocked the phone via mtk engineering from Google playstore to work with other networks
b. I have rooted the phone
c. Slot 2 does not detect sim as well ever since the problem ensued
d. This has nothing to do with sim management setting as I've activated it several times
e. I have cleared cache, clear user data a 'million' times in recovery mode
Thanks in anticipation to a solution.
