Problem with network - Galaxy S6 Q&A, Help & Troubleshooting

Hi all.
I bought galaxy s6 last week with android 5.1 (Network was still working). Next day I flashed stock android 6 with odin and then I flashed recovery, I rooted, flashed new modem and I installed Pure stock extra lite ROM. All worked, except network.. I can see that I have signal but when I try to call someone it shows "Not registered on network". So I try to flash new Alexis ROM with new bootloader (Hacker bootloader) but it isn't better and problem is still here. Anybody know what to do with this problem? Maybe try to install stock android rom with odin? I would be really greatful if anybody can help me..

Aha, restore your firmware through 'emergency recovery' google or youtube it for instructions.
= Emergency Recovery Smart Switch for *Galaxy S6* if necessary <
EDIT: Oh your network.. I'm afraid I just can tell you to do what I told you to fix it..
It will bring you back to stock Android 6 then root it..
EDIT2: Do what I told you and repeat all the steps you done:
Root and download the ROM but don't flash any modem cuz it will bring you back to the current problem.
Remember, no modems.

Is your IMEI still ok?
I made instructions on how to use Smart Switch here:
http://forum.xda-developers.com/galaxy-s6/help/how-to-smart-switch-emergency-t3383448
but it will revert you back to stock fw.
Check your IMEI/sn with *#06#
If you get IMEI null, or 3500000000006, you will have to rewrite IMEI with a box, and before that Smart Switch initialization won`t help.

So I did it and after Smart switch installed the rom it restarted and screen "Device doesn't have DRK"
EDIT: Now it boots to recovery and there it writes: "Device does not have DRK (Device Root Key), contact to SW PL. Please flash ENG binary then install DRK".
Does anybody know what to do with this?
EDIT2: So I found this video (https://www.youtube.com/watch?v=TSNbHvJdTk4) and I flashed space x kernel and it boots but it didn't solve the problem which I had.. still I can't make any call or sms.. Btw my IMEI is still same and it's fine.
EDIT3: It manually found networks but I can't connect.

That's weird.
Try to flash the ROM through Odin, grab it from SamMobile. Choose the correct model and region.
Tell me what happens.

Same after installation I have to also flash space x kernel (like in this video because it wouldn't boot https://www.youtube.com/watch?v=TSNbHvJdTk4) but network still doesn't work :'( I also tried other sim but this wasn't working too.

Hi Mlopik,
No your phone is not lost you just need to flash the modem you had before dealing with that problem.
Was the modem you flashed in the Aroma installer?

No. I flashed this like it was in guide of installation on pure stock extra lite rom. https://www.androidfilehost.com/?w=files&flid=50807 I flashed "G920FXXU3DPAD_MODEM.tar.md5"

I see.
So you flashed a modem you didn't have to use.
Usually using Smart Switch works and gets everything back as usual.
Please wait until someone knows about modems come.
Again, your phone is not lost, have patience and good luck.

Your welcome pal, I wish I can help you but modems are the last thing I will touch. Don't lose hope, try to flash modems, search for correct modem for your phone.
Good luck!
EDIT: I also recommend flashing more than 3 ROMS sometimes that helps. Try to flash XtreStoLite ROM and Terminator and any popular ROM you see. If it asks to flash modem in the Aroma installer do it, flash the latest one.

So I tried to flash all modems via odin from here ( https://www.androidfilehost.com/?w=files&flid=50807 ) to stock ROM with space x kernel and nothing happened Does anybody know what to do now? I can't find other modems to download
EDIT: I tried to flash many ROMs but it didn't help.. I tried to flash so many modems and problem is still same. Maybe I can try to go back to 5.1? But how? Only install 5.1 firmware from sammmobile via odin and it's all?

No, don't flash anything.
Just go to your recovery and do a factory reset. Tell me what happens?

[Q] CSC is unknown after ROM installation

Hi Friends,
I don't know that i should open a new thread for it. But I have searched in XDA forums no one is ask about this CSC.
Now coming to the problem, I have taken the backup(contact, message) from Kies and rooted and installed the custom rom(Frankenstine and after ZSLE5 for NEO). After installing the custom rom I am unable to connect my phone using Kies, it shows, no sim card.
I have re-flashed it with Stock rom and able to connect it. Hope this issue is because of the CSC(which becomes unknown) after installation of custom Rom.
Anyone else faced this problem?
Thanks,
Karthik

after flashing any of the custom ROM, if it shows UNKNOWN CSC ..
then flash only cache.img of your stock ROM via ODIN
Thanks dude
Thanks dude! I will check it now. You are very fast in replying like your ROM
download and flash the TAR via ODIN
(dont worry. It doesnt affect binary counter)
http://www.mediafire.com/?79gdtd0pxadrffy
Hey bro, if you flash a custom rom.. You will not be able to use kies.. So i advice you to use a different app to backup your contacts etc and restore after flashing the custom rom..
Kies only works on stock roms..

I was really dumb, and also did the exact same thing. In my case, I found my stock firmware and tried to flash using Odin (both 3.0.4 and 3.10.7) but ended up getting the NAND write start failure error. Is there anything I can do?
Please help!!!
Help!!!
I did the same thing also with SM-G920F. I deleted all partitions by accident.
I can't access recovery but I can access download mode.
I tried to flash stock rom with odin but odin does not recognise my phone.
I tried Samsung kies, I tried Samsung switch and nothing works.
Please help I'm desperate.

You need to fix the drivers to make your device detected by your pc
You may need to install samsung usb drivers or install them on another computer and try there

Did you get it to work? If not, check this link to download the firmware: http://forum.xda-developers.com/galaxy-s6/general/stock-firmware-official-stock-firmware-t3086387
I don't know which firmware Austria is supposed to download. I think it's based on carrier anyway.

If you flashed a stock firmware successfully it will not boot into twrp, flashing a stock firmware will install stock recovery, which means the stock firmware did not flash properly. Have you tried smart switch at all? Are you sure you have the correct firmware to flash through odin?

Yes I am sorry I didn't explained that. Atfer I tried to install stock ROM it got stuck, then smart switch didn't recognize the device but I manage to do the emergency recovery thing with model number and s/n but same thing it got stuck on the same installing system update screen. After that I installed TWRP via Odin to try to push a custom ROM zip, I did that but when I tried to install it failed.

Download Samsung SmartSwitch and from the upper menu select Emergency Recovery Mode, put your phone in Download Mode and connect it to your computer, enter your model number and S/N when asked, and it will download and install latest firmware for your model.
Sorry, i haven't seen that you already tried that.

That means TWRP works and Fastboot/Download works. What is the actual Galaxy S6 model? Mine is G920F.
What custom ROM did you try?
What version of TWRP are you using? The wrong one can create issues.
Did you wipe the phone trough TWRP first? Twice? Including internal memory?

Problem when flashing the Stock ROM

Hey everyone,
right now I'm running XtreStoLite MM on my G920F but I tried to return to stock ROM for different reasons. As usual I went into the download mode and opened Odin. I loaded in the Stock ROM but the first problem is, that after trying to flash hidden.img it fails. I already found a solution for that, that I have to flash it seperatley. But after flashing the hidden.img, my phone just shows "Galaxy S6" two times and then goes into the TWRP Recovery. When I try to restart the phone it will just go into the recovery again.
What am I doing wrong?
