[q] sm-n900w8 not registered on network

Hi Eveyrone,
I bought a SM-N900W8 unlocked from a guy. The phone has NOT REGISTERED ON NETWORK problem. I can see full bar but cannot make any phone call. The seller said he tried to flash cm and somehow screwed it up, so he reset and restore the phone to its original stock android. Right now im trying to make it recognize my sim. Does anyone have a solution for this? Should I root the phone and try region lock/ sim unlock?
Please let me know
Thank you
UPDATE: I still have my IMEI, its is the same as in the box
i have the same problem. Did u manage to get it to work ??

ATT note 3 help

So i recently flashed my device. I have an att note 3 i am having troubles using the wifi because everytime i turn it off or reset it the phone wont remember the wifi password or the wifi will get stuck on. I used to have 4.4.4 kitkat on it but when i flashed it i couldnt find the kitkat 4.4.4 and could only find a kitkat 4.4.2 that would work with my phone and actually flash my device i used for a tablet with an old sim card not connected to the network. I recently tried to put my girlfriends sim card in and update it off the att network but it wouldnt connect to the network even with her sim card in the device. I am having alot of trouble and its starting to cause fights between me and her and so i really need some help on how to fix this and update it. possibly a full factory reset. Also i removed a few of the att app that come on the phone the phone is rooted and superu is perm installed even when i factory reset through the boot settings it still is there. if anyone can help me out it would be greatly appreciated.

[Q] Not Reading Sim Card

Hey so i updated my LG G2 from 24A to 39A, but once I got to 39A my sim card could no longer be read. In the network settings tab it now says unknown and under Mobile network type it says disconnected. I tried bringing it back to stock 24A but it still did not work. I tried another sim card but nothing. Before I updated my phone I made a backup, but when I loaded it up it still did not work. I tried flashing different Roms but no dice. Its weird because I can use wi-fi calling and everything works. It is only when I am not on wi-fi where nothing gets read. Can anyone help me? Any help would be greatly appreciated.
Thanks
are you by any chance having this problem when you try vexxoaosp?
Im not entirely sure which one that is, but I dont think so. Could you provide a link to it so I can try it?
I don't think you should try it then.
Sorry mate, did you do a stock reset with a kdz file fitting your model?
I recommend you to use LG Flash Tool 2014 with a stock kdz file. There is a thread about it here.
I tried that...multiple times lol
Did you contact your service provider? Any warranty left?
I bought it second hand, so unfortunately no warranty

WiFi will not turn on due to no Sim Card

I've searched for 2 months trying to figure this out. Basically my sim card will not be read due to the hardware issue so it is the motherboard, now the problem is i cannot enable WiFi due to not having a sim card inside the phone...when i was on 4.4.4 it says Smart Network Switch and something about not being able to enable due to no sim.....well i tried a custom rom to see if it would remove that feature which it didnt so i went back to 4.4.2 and it doesnt have the smart network switch but it still doesnt allow WiFi to turn on....now the funny thing is before i had the Sim problem i had WiFi on and it stayed working after the sim stuff happened, I factory reset my phone when i was going to install a custom rom before evening knowing WiFi wouldnt work without a Sim so obviously to my surprise when i went to turn on WiFi it wouldnt work, seems like the S4 has a stupid feature imo that if you dont insert a Sim it wont allow WiFi to be turned on. Can anyone tell me if under root or something i can get rid of that feature or some how turn on WiFi in the files or root section of the phone?

I have a similar problem. I have an AT&T S4 I337 that was used with Net10 Network and had the intermittent sim disconnecting problem but it was working well when ik worked. After I changed the Net10 sim to an AT&T non subscribed sim the Wifi, GPS and Bluetooth stopped working. I thoug hit was some firmware problem so I decided to Odin flash the NB1 Rootable Firmware but the problem persist ( can turn wifi and bluetooth on, and GPS turns on but cant get a location). I also tried the complete stock version of NB1 and also did not work. I constantly get a security Notice saying "Unauthorized actions have been detected. Restart your phone to undo any unauthorized changes". I restart but the problem persist. It seems to reboot into a Recovery booting and then restarts. The thin is that the Knox counter is still 0x0.
Did you resolve your problem? If not could some one help us PLEASE!!!!!!:crying:
Any one with that could help me identify the problem?
