In another device, this sim card works. Happened after the firmware with formatting UMI S2 device. I ...

Nvram in Umidigi S2 doesn't contain any different data than this one which can be restored with SN writer. (IMEI numbers, Wi-Fi and Bluetooth address)
I would recommend full format, download latest firmware and restore other data with SN writer.
Here is SPFT instruction

So I don't know what have you done.
Maybe open phone and disconnect battery.
Of course this will void warranty.

I would not like to resort to such measures.

Yes, I installed the firmware with the formatting of the device memory.

Hello, I have the same problem. Umidigi, Could you please provide the nvram.bin for flashing from the flash tool? I am quite sure that this will help to anyone with such problem. Really need this. Thanks in advance!

You no need nvram.
Please use SN writer and restore IMEI numbers.
Here is SN writer instruction

Hello, Thanks for your response. I have restored the imei but the signal did not returned. Still no service. I have tried about everything. The only thing that is left to try is to restore nvram.bin because I am quite sure that the nvram is corrupted. I have fixed similar problem with other mtk phones by simply restoring the nvram.bin from the flash tool. So If possible, Please provide it. It would really help. Thanks in advance!
