[Q] Restricted access changed - MT6575 S4 Clone
I purchased a MT6575 S4 Clone from abroad.
I noticed that with supplied IMEI number restricted access changed message would appear and there would be no connection to my UK mobile network.
Afters pending numerous hours researching and failed attempts to change to change from GSM to WCDMA only - even using apps such as mobileuncle etc.
I changed the IMEI number to another S4 clone I purchased and this appeared to have temporarily resolved the problem.
It connected to my UK mobile network and the phones voice calls etc worked.
However 24 hours later I noticed that every 3 minutes or so it would revert back to restricted access changed message and no network and then back again to the mobile network.
I don't want to have to keep entering new IMEI numbers every 24 hours or so for the mobile to work.
Although I noticed the other S4 clone appears to do something with auto generates new IMEI numbers by itself.
Can someone help me resolve this with a permanent fix please?
I would be willing to install a new firmware etc if basic instructions are provided which include backing up?
Ideally keeping the workable S4 theme and features.
I did briefly try MTKdroidTools and backing up did not appear to work on there.
