Hello!
Long story short, I bought a dual SIM Edge+ (G9287) but found out I can't use my second SIM in it.
I tried flashing Audax ROM which doesn't have support for my model and it worked just fine, but couldn't detect my SIM card (even though I'm only using one).
So my question is, can I use SM-G9287C firmware on my G9287 and then flash some ROM? Will it work or will it brick my phone?

Just curious, when you couldn't use your second sim, were you on stock firmware? If yes, did you enable the 2nd SIM in settings? Setting->SIM Card Manager -> 2nd SIM and turn it on with the toggle.
My phone is G9287C which is a dual sim as well, there's a workaroud to make the dual sim work on CRISSCROSS ROM, though I'm not sure if the same goes for other ROMs. However if the 2nd SIM doesn't work with stock firmware, I believe it wouldn't work other ROMs too.
Naw I couldn't use the second SIM because it's from my work phone, I work for the government and they got retarded protection so I couldn't set up my email and few other things and they also forbid removing SIM cards from their phones. So I had to accept not using the second SIM card.
But when I flashed Audax then I was not using stock firmware, although I was using older G9287 firmware (J7, since it was apparently the only way to be able to successfully flash custom recovery as my old K5 would just re-flash stock recovery after every restart). Still, it would not recognize my home SIM regardless if it was in slot 1 or 2.

Not sure if it works, but worth trying:
1. Get these 3 files from your stock firmware under folder /system/lib64/
i. libril.so
ii. libsec-ril.so
iii. libsec-ril-dsds.so
then copy to the same folder and overwrite the files after you flashed the custom ROM. Make sure those 3 files are in -rw-r--r-- format. Wait 20 seconds see if the signal icon appears on the status bar.
2. If signal icon does not appear, flash other kernels like arter97 or anything.
3. You might need to flash the radio/baseband "modem.bin" from your stock firmware.

Thanks for trying to help, but I was looking for an answer if the phone will work normally with a firmware from one of the single SIM models
If it works, then I can just flash it and then use pretty much any Edge+ ROM without having to edit much.

Ah, my apologies for not reading your question properly. Just for your reference tho, I have only tried Crisscross and Kos ROM and both didn't detect my SIM card. I believe the same goes for all other ROM since they only support single SIM variants, reason being the baseband and RIL are different from ours.
Ahh so I guess not even flashing firmware from a single SIM model would work :/
Last time I'm buying dual SIM anything.

I have also SM-G9287C (dual sim) and I am interested to flash custom ROMs. So far no custom ROM for my dual sim phone is available so I have to flash single sim custom ROM. My question is, will your method work with every custom single sim ROM?
And how to flash radio/baseband "modem.bin"?

I don't know if it would be able to run every custom rom. But as far as I know, my phone is able to run Crisscross rom 1.8 smoothly (haven't tried the latest one 1.9.1) without any hiccups.
Regarding "modem.bin," get the stock firmware from sammobile G9287CDXU2AOK1 (this is the latest one but any stock rom in tar.md5 format will do). Open the file and extract modem.bin (can be done with 7-zip). The Crisscross rom 1.8 doesn't overwrite the baseband (the latest 1.9.1 might wipe the baseband) so this step is just optional and if anything goes wrong you can do this afterwards. If your current baseband is G9287CDXU2AOK2, you can leave this step.
Remember the step 1 I've mentioned in the post earlier is the most important step of the 3.
p/s: I also did this tweak on my phone and it runs even smoother, http://forum.xda-developers.com/s6-edge-plus/general/root-ram-management-multitasking-fix-t3228917
I have 9287 using dual sim and only one card can use 4g while another is 2g only did u check the gsm frequency is supported by your carrier http://www.samsung.com/hk_en/consumer/mobile/smartphones/galaxy-s/SM-G9287ZDUTGY

So as a conclusion, can you use Crisscross ROM on 9287 with at least one sim card working? Thanks in advance if you clear this up with details

pm you few days back and still waiting for reply.
Fenrir_ac,
I am also on the 9287. I tried installing CrissCross 1.8 and 1.91 and both times they made my baseband version Unknown and it couldn't read my SIM. I installed a clean stock ROM before i installed both 1.8 and 1.91. I then tried installing the modem.bin from a stock ROM using Odin and the CP option and that didnt work either. Can you please put a detailed description on this thread how to get CrissCross working on a 9287. Thanks!

It's worth to note that my phone is g9287c variant, not g9287 without the letter "c" at the end. It is still a dual sim variant, I faced the very same issues before (sim card not detected on both slots), and therefore I'm just assuming the fix that I did on my phone MIGHT work with your phone too. I'm not a developer so I have no idea what risk would involve in doing this. If you still wish to do so please do it at your own risk.
Few Questions:
1. Are you on stock ROM now? What is your current bootloader version?
2. It makes me wonder why your baseband became "unknown". Did you flash "modem and bootloader" file provided on the CRISSCROSS ROM thread? If yes, please DON'T flash it on your next attempt.
3. When you flash Crisscross ROM 1.8, did you dirty flash instead of clean flash?
4. Did you port over the 3 RIL files ( in the /system/lib64 folder that I mentioned in earlier post) from the stock ROM after flashing Crisscross ROM? It's the most important thing to do.
Here's what I did to make CRISSCROSS 1.8 to work on my phone.
1. Get the latest stock ROM and flash it on my phone, extract the modem.bin file just in case.
2. Update the stock ROM (if there's any) with the built-in software update.
3. Backup somewhere these 3 files from /system/lib64 folder (MOST IMPORTANT STEP!)
i. libsec-ril.so
ii. libsec-ril-dsds.so
iii. libril.so
After back up, flash TWRP with ODIN.
4. DIRTY Flash CRISSCROSS ROM 1.8 through TWRP recovery. I did not flash the latest 1.9 since its a requirement to perform a data wipe.
5. I did not flash the "modem and bootloader" provided in the CRISSCROSS thread.
6. Wipe dalvik and cache after flashing CRISSCROSS ROM. Reboot system and wait until the phone is ready to use.
7. Move the 3 backed up files earlier and overwrite it to the same folder (/system/lib64). Make sure the three files are in -rw-r--r-- format. I'm not sure if root is required for this as it involves overwriting system files.
8. Wait 30 seconds until signal indicator magically appears on the status bar (Only one SIM will work at this stage. The provided AUDAX kernel does not support dual SIM).
9. Reboot to recovery and flash the latest arter97 kernel (v11).
10. I did not flash modem.bin through ODIN since I found that the Crisscross Rom flash did not touch my baseband.
11. Reboot system and turn on your second SIM option in Settings>SIM Card Manager.
Hopefully this will work on your phone. As usual, do a nandroid backup before performing this just in case.
1. I am currently on stock ROM, J7. This was the only Firmware that allowed me to root. Bootloader Verison G9287ZHU2AOJ7
2. I did not do that. All I did was install the zip file in recovery. How am i supposed not to install those files.
3. I did a clean flash on both attempts.
4. No I didnt. I need to do that next.
I will attempt this sometime this week and give you feedback. Thanks for the write up. I also have a problem with artex kernal and Audax kernal where it causes major lag issues for my Gear VR so it looks like i have to use a modified stock kernal.

At first flash lolipop stock ROM.Full guide is here.Then flash cm13 by @ED300.
Bro Lenovo a6000 plus firmware downloading link fail.
I have solution
Bro first of all test those sim cards in another mobile , if they were fine then you have two remove both sim cards from your device and then reboot to recovery and flash stock rom (if you have kk based rom installled then flash only kk based pure official stock rom only or if you have lollipop/marshmallow /naughat based rom installed then you have to flash only stock pure official lolipop rom ) . For flashing stock lolipop rom first extract that package and move system.zip and another country named file which one you want i recommend you to use your own country file , after that flash only these to system.zip and country zip via recovery first flash system.zip and then country zip and then super su . And after flashing stock rom don't forget to flash your twrp recovery ( for example- for stock kitkat flash kitkat based twrp.img and for stock lolipop flash lolipop based twrp.img and then flash any supersu.zip file ) remember the step of flashing twrp recovery again before rebooting otherwise you will permanently loose your twrp and root access .This simcard error comes from persist partition (you can easily see this option during mounting any file system in twrp recovery) . I am damn sure that you accidentally wiped this partition , but don't worry if this is not a hardware related problem you can easily make your device to work properly with your sims, Another tip please flash those stock roms without sim cards and don't insert sim cards until your phone turns on for first time after that you will switch off your phone and insert sims. Wolla you got your sim connection back. I am again saying flash stock rom only without any sim . If these steps dont work contact me via WhatsApp - +91 9205097520 or simply reply me on xda or mail me at [email protected] . I hope you understand the steps :good: .
And don't forget to tell me about your device problem
. Any time you want help iam ready for you guys.
sometimes the sim slot is loose for sims when we put in our micro-sim my telenor PK works flawlessly on both slot 1&2 while i couldnt get my Jazz/Warid one to work and the solution was to add a piece of paper on the sim over slot 2 to get it read otherwise im sure your issue was resolved by the previous person who posted
I was on stock KK ROM . I wanted to try the Mokee 7.1.1 so it went to twrp flashed the KK2LP firmware switch zip and then did a clean wipe and flashed Mokee and gapps . It was stuck in the boot animation. So I went to twrp and flashed the ED300 cm12.1 and it booted .And after rebooting both the SIM cards are not getting detected. But the carrier names are written cannot connect to network. Again I flashed the Mokee and error was also present in that.
So I reverted back to stock LP ROM by flashing stock recovery for LP and flashing the System.zip from the LP OTA zip that I had.
It flashed successfully and on booting it too didn't show the network but the carrier names are present.
Please provide a fix for this .

Sorry for my English, but I'm Panamanian ... I have an S7 that I installed RROS and now the phone does not detect the SIM card, and I need the libsec-ril.so file to fix it. Can you help me?
Go to stock rom via odin and then your sim will work fine .After that make a backup of efs and then after Installing your custom rom you can just restore that backup and sim will work fine..

That's the problem, and that is that my phone does not allow the installation of Rom Stock, because I bricked my phone, But currently it only works with Custom Roms
Hello, I wanted to know where I can get the firmware of the j730f / ds version 8.1 if possible, in the same way any other would work for me. To install via recovery or twrp, no Odin (damaged connector) ... greetings and sorry my probably wrong English
Hmmm
I understand your problem
I am not a pro, but have found some roms for you (install through TWRP) All are Custom Roms
Clean Pie
Clean Oreo
S9+ port rom oreo for j730x
Hope these will help you, But try at your own risk
Hello, i install all of these roms and my phome never find a sim card. I try to flash sboot files via odin 1000 times but not success. No sim card recognized and phone are dead. Anyone knows a solution?
