4G LTE is not working on my D620R. Only H+ works. Anyone with the same problem?
How to resolve it?
I will assume that it is a mtk phone.(that's what most clones are)
Try to boot it with power&volume up or power&volume down.
If it doesn't start,sadly it's a hard brick,and you throw away the phone.
But,if it starts,tell us the mt version.
