[X2 Android Development] javirix:
Thank you! Your solution for offline SIM worked in my Nokia X2 DS (RM-1013)!

Hi Karachi,

I would like to thank you very much because your "SOLUTION FOR NO SIM" procedure has solved my SIM offline problem in my Nokia X2 Dual SIM (RM-1013) device.

After installing the CyanogenMod 12.1 suddenly I totally lost the RIL connection and my Nokia X2 DS device could not do any SIM1/SIM2 call or any SIM1/SIM2 data connection. I tried all kind of SIM combinations but nothing at all solved my problem. The only thing that appeared on screen was that SIM cards were in some kind of weird offline mode. At least I had correctly the IMEI's numbers inside, they were NOT null, but the SIM cards appeared as totally offline mode without any option to recover the radio connection.

I tried all the different solutions that appear in XDA and other Google found webs, but none of them worked for me:

- reinstall all the CM12.1 ROM using the different wipe options

- install the famous path1 and patch2 zip files

- launch the terminal emulator ril-daemon commands

- reinstall the original Nokia stock ROM

I could not find any solution at all and I was going to give up totally: my phone was going to become an only WiFi device and never a phone anymore. But after googling for "nokia x2 dual sim sim card offline" I found someone that was saying that "NOKDROID_V1.1_FOR_NOKIA_X2.zip" custom ROM could solve the SIM offline problem. I was very lucky to read such comment so after finding the XDA entry here, I did not install the NokDroid ROM but I read your interesting solution "FLASH ONLY MODEM - SOLUTION FOR NO SIM NO WI-FI" paragraph and I tried it.... and it worked!!!

Finally, I have again my Nokia X2 Dual SIM (RM-1013) now with CM11 and the SIM1/SIM2 working again: voice calls and data connection are working without any problem. THANK YOU VERY MUCH!!!

So here are the steps that I followed just in case it may be useful for someone that has also a RM-1013 device (Nokia Ara = Nokia X2 Dual SIM) with CM12.1 installed inside but with the SIM offline problem (no voice calls possible, nor data connection, although the IMEI's are not null and appear correctly in the Android settings):

1) download the "NokiaX2_modem_flashable.zip " file

unfortunately, it is not anymore available in this XDA repository but you can find it still if you google "NokiaX2_modem_flashable.zip "

I found the zip file in next link : https://androidfilehost.com/?fid=1395089523397967915

2) follow the Karachi steps that are very simple to do

you only need to have a custom recovery installed in your Nokia X2 device

in my case I had the TWRP but you can google others :

there is a tool that does it automatically in next link :

once you have the custom recovery working properly you can follow the Karachi steps

> install the "NokiaX2_modem_flashable.zip " file in the external SD card that will be then put inside your Nokia X2 DS device

> boot up in recovery mode (power off -> volume up + power during some seconds -> TWRP appears)

> click the Install option and then select the "NokiaX2_modem_flashable.zip " file

> wait till the process is completed on screen

> click the "Reboot System Now"

3) when Android restarted with CM12.1 release, I could see that finally a SIM radio bar icon appeared in the status bar... finally !

BUT the problem now was that although I could see the radio icon, when I tried to do a voice call, the phone crashed and restarted automatically

there was a strange exclamation symbol in the radio icon and each time I did or received a call, the phone crashed suddenly and Android restarted

so although it was better than nothing (SIM offline) there was still a big problem because Android restarted each time I tried to do or receive a call

4) so how did I solve it?

I decided to install the CyanogenMod 11 ROM that is based on Android 4.4

why? because I read that CM11 did not have any RIL issue, so I wanted to try it just in case, now that SIM's appeared again correctly in the Android bar

to install the CM11 ROM you can follow the same XDA link than for CM12.1 because the links still work (or google them wihout problem)

in XDA here it is : https://xdaforums.com/nokia-x2/development/rom-cyanogenmod-roms-nokia-x2-t3295230

after installing and booting up the CM11 ROM the two SIM cards appeared correctly now in the status bar

remember that SIM cards must be inside the device when you install the CM ROM's

I tried to reinstall again the CM12.1 ROM but unfortunately the OS crashed each time I tried to do a voice call, but at least I have now CM11 working fine!

Cheers!
