S5 clone mtk 6582 g900f nvram topic

I have the following phone which is an S5 Clone.

The phone does not detect the Sim Card for any reason. I tried fixing the IMEI but to no avail. I think the NVRAM is broken and I dont have a back up. Can anyone help me acquire one.

[Q] Rooted MTK 6582 not detected after factory reset topic

Hello to everyone. First of all sorry for my english!
I bought a Sophone i6 plus (mtk 6582 device) but when it goes on deep sleep mode it stucks. I solve this problem with an apk that woke up my moblile phone every 19 minutes.
Then the rooted phone stuck on boot image and there was no response.
So I try factory reset from recovery mode. Now when I try to turn on my mobile phone show me media tek logo but nothing more. I can not use recovery mode , also my pc does not deteced my mobile's phone device at all. :(:( I believe that the problem is that I can not conect my device an my computer.
Please help me!!
