you can open it very easy, just Press and hold on power button And a volume up button and home button on same time, When it works Lift your finger off the home button and volume, still hold in power button, Then you will see some choices, Just chose wipe data factory reset then yes, Then go back to the first list chose reboot system now, (((The phone will return as new))).
I've already had this problem before and resolved it by: Looking for USB Driver for my phone Then I installed it on the computer and was able to Identify the phone afterwards
I advise you not to remove the shield from the logic board, even if removed it must be returned to its place because it has a important function, They protect the components beside them from the heat, Such as processor heat
In fact yes it can be compatible with the phone in dimensions and all other specifications But there is one difference which is support 2 Sim So I do not guarantee full compatibility With your phone So I advise you upgrade to this model E2306 it have 16 GB Rom
