Info 2 [Q] F180K modem is not compatible with E975 stock roms?

Hi. I found the MIUI 4.8.1 based on E975 20A Thailand firmware in Android development thread.

http://forum.xda-developers.com/opti...itkat-t2839043

here is link.

I have F180K korean model. When I flash this rom, it successfully boot. But it says 'no service' and cannot find carrier.

How can I fix it? Any other roms which are based on E975 stock firmware like ARTMOD 4.1ST etc. is available to flash, but always communication error.

Stock rom use different ril library for different model, If you want to try you can replace /system/lib/libril-qc-qmi-1.so with F180K Kitkat rom. And maybe /system/etc/telephony.xml. I'm not sure it'll work.

But what I did is compare all files from 2 roms and get all different file to make a patch. It works for my patch to change from Thai firmware to German. (I also change kernel but I don't think there are anything relate to mobile signal in it)

A lot of Korean forum people are saying thank you.
They can flash rom successfully but can't get signal bars. But when they try your method, all people are getting signal bars and communication.
Thank you one more time.
