Simcard not detected

Hi,
I have a n9200 Chinese version of the note 5.
I recently tried to flash a custom ROM on the device because I wanted to try nougat, but seems like most of the stable ROMs don't boot on the n9200 or something not working (2nd sim slot e.g.).
I decided to do a restore in TWRP of my stock rom.
However, the SIMcard isn't detected anymore.
"Insert SIM card" message appears if try to click on 'mobile data'.
I did a full restore of the rom, including radio, so shouldn't everything be as before?
I did also try to flash other ROMs, but the problem remains..
Do You have any advise of what to do?
Is it worth trying to flash the modem in Odin?
I assumed that it restores the modem if I do I restore of the radio in TWRP.

Ok. So I have done some research, and I came up with two possible causes to this problem..
1) I bought my phone (n9200) region unlocked, could the lock have been reactivated when I loaded a new rom?
2) I did a back up of my stock /efs partition before flashing anything.
However, I cannot find any .nv_data.bin in the efs folder... Could this be a problem? Are there phones without this file?
Would be grateful for any help. I have tried flashing different stock firmwares through odin, but the problem remains...

You should try ODIN flashing the stock firmware you were using when you first flashed TWRP. Bringing it back completely to stock including the stock recovery might set things straight. If this does not work you might need the PIT file for your device for flashing in ODIN. Best of luck.

Download the latest firmware for your device and flash it via the latest version of Odin. I had a similar issue where I flashed a custom ROM and lost service completely. I simply flashed back to complete stock. I got my stock firmware from sammobile, may take you a while but it'll be worth it cause you can then keep that file and always have a stock backup handy. Do it all the time.

Help plz

Did any one fix this problem???

Yeah, I actually solved it
It never worked to restore with Odin. SIM card was never recognized.
I did however download an official Samsung application (think it was smart switch).
I could do a factory restore of my n9200 through that application and its fixed the "no SIM issue".
i hope it will work for you too.

Try flashing a different modem.
You can download stock firmware from www.sammobile.com and extract out whichever modem you need. Flash it via oden.
Or look at the Note 4 subforums for a list of individual modems posted.

Signal lost inmy redmi 4x device, but...

I lost my sim card signal, in which i was rooted and on custom rom of RR final version, what happend in real is the sim cards (2) working fine in my phone but one of the sim card is getting less signals and i thought to change the network mode in settings as well as in *#*#4636#*#* mode by on & off the radio option, by doing that i lost both sim card signals, then i flashed stable ( stock) rom from official website then i got sim 2 in working and sim 1 no signal, then i flashed with RR custom rom by rooting again then i lost sim 2 signal and i got sim 1 back, it was full of confusion, then i was back to stock rom
Now i started doing process with adb& sdk by changing modems and all but nothing changed
At lost i lost both the sim card network.....
But other sim cards are working perfectly in my phone and my non working sim cards which i used in my phone were working fine in other phone as well..
At last i even tried to give for service center they even could not doing anything .. (they try very hard)
So guys, what do u think were i made a mistake in this process, please any suggestions..., thnk you in advance.,

do you restored the same network setting back ?

Download any official global recovery rom for your model and look inside the "firmware update" folder you will find modem fileb"NON-HLOS.bin". Extract this file to pc inside fastboot folder and open fastboot then connect your device in fastboot mode and type the following lines one by one.
fastboot devides
fastboot flash modem NON-HLOS.bin
fastboot reboot
Now your device will reboot and you get your networks.
Try this if you still having that handset. This method will work 100%.
Incase you need modem file only then feel free to contact me.

(HELP) xt1922-7 need the NON-HLOS.bin file please!!

Hi, I tell you ... my sister bought a liberated American g6 play. the question is that it would not let me put any apn or modify anything, read out there that changing software fixed that since some operators blocked that so they could not use it with other operators. en din decided to flash stock rom and found the ROM ALJETER stock for the xt1922-3 as I saw it was the same model I decided to flash it and then it happened ... all well no error but now I have no signal of any kind or wifi or data etc, I wanted to see if someone who has this equipment could pass me a backup of the modem or the system backup of xt1922-7 PLEASEEE!!! :crying::crying::crying: The backup of the modem or the NON-HLOS.bin file or the complete backup system... thanx!!

You can find the stock firmwares from the G6 and 6 play here. I'm not sure what model you have based on the numbers.

No signal after crossflashing

I tried flashing a sea region firmware but when I finally boot it up, the signal bar shows nothing. Everything else works as it should do. Another weird thing is the netword mode is stuck on "22".

Need more information to help you. What region is sea region and did you mean network stuck in 2g? Network mode is either Global or LTE/CDMA or LTE/GSM/UMTS. If I remember correctly from the one time i wiped the modem and IMEI number from a phone, it did that. Did you accidentally do 'ChipErase' in LGUP? Please provide more information, may be a screenshot to get help. Thanks.

Make sure you are using most compatible LGUP, the Dev patched dual LGUP from this post has never failed me, download it at bottom of post# 168 and don't forget to hit the thanks button for Chazzmatt and other contributors:
https://forum.xda-developers.com/showpost.php?p=76510671&postcount=168
Also, make sure you have the right KDZ for your phone, what was the phone's original model number and which KDZ did you flash to it? Make sure you use 'Partition DL' in LGUP.
Did you cross-flash by jumping from Oreo to Sea region Pie? I have read that jumping straight to Pie like that can cause issues. First try to fix by using 'Partition DL' in LGUP as i just mentioned, if that doesn't work, download your original model Oreo, reflash that using 'Refurbish' or 'Partition DL', then download and cross-flash to Sea region Oreo using 'Upgrade' option in LGUP, from there try flashing Sea region Pie using 'Upgrade' option.

'Partition DL' is a flashing option in LGUP. When you pick this option and it starts flashing, pick 'Select All' option in the new window that opens.

First try flash Pie (Sea region firmware that you already downloaded) using 'Partition DL' option in LGUP. That should work, if that doesn't work:
Download and flash Oreo (LM405EBW version firmware) using 'Partition DL', set up the phone, enable developer options, then download and cross-flash Oreo (Sea region firmware) using 'Upgrade' option in LGUP, then try 'Upgrade' again to flash latest Pie for Sea region.
---------- Post added at 02:26 PM ---------- Previous post was at 02:14 PM ----------
Did you download the Sea region KDZ file from LGFirmwares website? It seems it is not a complete KDZ, it is probably an update file as it is only 340MB and a normal KDZ for LG V40 is around 4GB. If nothing above works, you need to download and flash Pie for LM405EBW (original software you had on this phone) using the 'Partition DL' option. Then flash the Sea region update KDZ using 'Upgrade' option.

If you can't finish setup no worries, just turn phone off. Then hold volume up button and plug in the USB cable to enter download mode and you can use LGUP to flash again. But, make sure you flash a full KDZ as I suspect you are flashing partial file and having all these problems. First recover from these errors then worry about flashing Sea region. go to LGFirmwares website, download a full 4GB KDZ for LM405EBW model. I feel that you didn't download full KDZ since last post because LGFirmwares website is very very slow and it takes many hours to download a full KDZ...
Edit: And whatever you do, do not use any options in LGUP that you don't know about, especially the 'ChipErase' option, it will permanently break/brick your phone. Once you flash a full KDZ and run setup and if still have issues, please go into settings, 'System', 'About Phone', and 'Status' and do you see your IMEI number shown or not? If it is not showing you may have used 'ChipErase' and there is no easy way to recover from that.

In this particular case, the ChipErase did help me get the signal for cellular data and wifi back for me. Eventhough the IMEI is gone but everything now works for me.

It is funny that I suspected right away this is what you have done even though you were not very forthcoming. If you are looking for help from others on this forum please be considerate of others' time and effort by providing all the necessary details so we can help you effectively and efficiently.
Just know that (and let it be a warning to others reading this) ChipErase not only erases IMEI numbers but i think it also erases MAC addresses, EFS partition etc.. In many countries if your device doesn't have IMEI number or other identifiers, sim networks are not allowed to let you register with them, in other words, in most cases your sim will not work in this phone and you will have no cell service. You seem to be lucky if network you are using is letting you connect with them. With most networks you will not have cell service. You will even have issues with Wi-Fi networks as without MAC addresses for your Wi-Fi will either be greyed out or network might not let you connect.
Also, know that in many countries around the world knowingly tampering with or changing your phone's IMEI numbers is against the law. IMEI number is how networks and ultimately law enforcement identify the device and their owner.

Hello. After using the DL partition in lgup, my S / N and IMEI SV disappeared ... The phone now does not pass the safety net check. Would you know how to fix S / N and IMEI SV?

Partition DL wouldn't do that, are you sure you didn't do 'ChipErase'? If you didn't, download KDZ again and try reflashing?

I'm 100% sure the dl partition did it for me. I didn't use chip erase at all. Reflashing didn't help me. I didn't miss the IMEI, but the IMEI SV and S / N ... And when I looked into the system, the phone wouldn't load build.prop ... Maybe it's related

After tinkering around in the setting I found that my model turned into V405UB instead of the real model V405EBW along with the second sim tray doesn't work anymore

Partition DL does not mess with your IMEI number or Serial number. I dont know if a corrupt or incomplete KDZ could cause this? I suggest that you download different KDZ and make sure it is around 4GB in size, md5 match up, and flash that and see if IMEI numbers return.

After tinkering around the settings, I found that my model went from EBW to UB and the second sim tray no longer works

I don't have a S/N for mine either. Don't know if there was one there before I cross-flashed. Does it make a difference?

Hi Android #. I downloaded several FW and after reflash the result of the meetings is the same. IMEI SV and S / N are missing ...
But it's weird that Lgup from this post: https://forum.xda-developers.com/showpost.php?p=76510671&postcount=168 helped me fix the signal loss and LGUP from this: https://forum.xda-developers.com/lg-v40/development/lg-1-16-t3967559 did not fix it for me ...

I also don't have S/N after cross flashing but I do have IMEI
