K yeah I'm running TW LP already. I have an issue though with battery drain when using WiFi. I'm hoping that flashing CM12 so I can use their kernel and modem/radio might fix the issue

Edit: I also have a problem where sometimes I don't receive text messages if WiFi is turned on. I think the problem started when I dropped my phone, fingerprint scanner isn't working either, but still hopeful CM12 might help
[Galaxy S 5 Q&A, Help & Troubleshooting] br34k:
Okay so I think I figured out what is going on.. you're saying that on a stock G900FD/MD lollipop ROM install I can flash the ktoonsez kernel you provided in post #27.

Does that replace the stock samsung radio ROM as well? How often does the error notification appear?

No Sim...
[Galaxy S 5 Q&A, Help & Troubleshooting] gunde2014:
I've noticed you can't even encrypt the device on CM12 or CM12.1 on SM-G900FD.

When you reboot it will go into a bootloop. Also I've tried 3 different CM12 ROMs all of them read no SIM for SM-G900FD. And with the newer CM12 ROMs releasing (March 28 build for klte gsm) it doesn't support Xposed module for lollipop anymore. Even the developer doesn't intend on writing Xposed for lollipop 5.1 anytime soon. He's more focused on making Xposed stable for lollipop 5.0 - 5.0.2 which is still Alpha at the moment.

Hopefully we can at least get this sim card working with proper baseband.
[Galaxy S 5 Q&A, Help & Troubleshooting] gunde2014:

[Galaxy S 5 Q&A, Help & Troubleshooting] hawst:
Once we fix the sim card, exactly that moment we can release CM12 for G900FD
[Galaxy S 5 Q&A, Help & Troubleshooting] gunde2014:
CM12 and CM12.1 both work on SM-G900FD. Only the SIM card doesn't work so no mobile network. Since the SM-G900FD is a duos it was expected to be support by CM12.1 for dual SIMs but it's still not working.

Earlier post we can see the devs got CM12 to show up 2 sims in the settings. Also in SIM port 1 we're able to see available networks but can't connect. You could currently get this by flashing the zip file and changing the build.prop

Also once we finally get this SIM resolved please devs compile it with lollipop 5.0.2 because Xposed doesn't support higher than that yet.

I don't give a **** to xposed... most important is to work both sim cards.... and why to go back to 5.0.2 when we have 5.1 ???
[Galaxy S 5 Q&A, Help & Troubleshooting] hawst:
I dont think it matter, either 5.0.2 or 5.1, if we can make any of it to work - then will be not big deal to make work another. As i wrote already - its same issue even you flash G900F rom to G900FD, even 1 sim not work with same reasons.
[Galaxy S 5 Q&A, Help & Troubleshooting] gunde2014:
What results? Ktoonsez is leading this project. He's worked on the S4 that's had dual sim and got it working as well as many unofficial builds for klte.

---------- Post added at 08:52 PM ---------- Previous post was at 08:48 PM ----------

Only stock ROMs for SM-G900FD and SM-G900MD will support dual sim that actually works at the moment.

[Galaxy S 5 Q&A, Help & Troubleshooting] dj_tselis:
i can also help by testing the ril.
[Galaxy S 5 Q&A, Help & Troubleshooting] k2wl:
i dont know much of a java either so you have to pull the logcats and understand what is wrong with the ril.

basically this is java hacking and understanding of ril used by this phone.

most of developers write their own ril based on stock ril.

donating device to a senior developer is excellent idea.

may be @hawst and @ktoonsez know some of developers with excellent java knowledge or donate the device to single sim cm12 developer.

that way he can maintain both devices.
