After flashing some roms and custom kernels my S7 edge which was unlocked couldn't identify my SIM card. It detects it but it doesn't show the service provider name and there's a notification which asks me about an unlock code. It's the first time I've come across a problem like this where an SIM unlocked phone seems to have turned into a locked one. I've already done factory resets, flashing the latest bootloader and modem, switching to another SIM card (same result) but nothing works. Is it one of the files being modified or related to hardware?
Currently I'm using Phoenix ROM v3.0 and VoLTaqe 4.2 kernel (best one i have). Also, other roms i flashed also had the same issue.
same here. Eve figure it out?
Was it originally unlocked or was it unlocked with a pin? Some pin unlocks are dubious and only last until updated/flashed.

Before you judge me by saying how i'm posting something thats done before, it hasn't, I've searched everywhere no methods work
Please, someone help me I've been at this for 4 days now and maybe just 15 hours of sleep :crying:.
The phone I have right now is the SGH-i337m Galaxy s4 running NC1 with MDJ modem (Kitkat 4.4.2) Does not detect sim, it says "No sim available".
I'm not exactly sure if the phone is from Bell but the phone use to be running fine on my old rogers sim card until I updated to their new ShareTap Sim.
With the ShareTap Sim the phone doesn't detect my sim anymore. So I tried my Share Tap Sim in another unlocked phone (Galaxy note 3) it worked fine.
Then I tried a Virgin mobile sim card on the S4 and it detected it and worked fine also. So then I tried to unlock it by flashing it with many different methods:
1. I tried flashing a older version of Bell 4.2.2 but it bricked my phone ( I already unbricked it back to 4.4.2)
2. I tried flashing the MDJ modem but it doesn't show the hidden menu.
3. I tried flashing ATT modem to try it but that also bricked my phone.
4. I tried to use the AWS tutorial shown here
5. I tried the regionlock away tutorial here in the third method (RegionlockAway doesnt do anything to my phone)
6. I pulled the modem.bin from the TAR file from sammobile of Bell's 4.2.2. But it still doesn't show the hidden menu! It's the MDJ modem but it still doesn't work!
I'm not sure whats wrong with my phone. When I put the Virgin mobile sim card in there it only shows Telus, EXT and Virgin Sim networks available not the whole spectrum which is what is supposed to happen with the 337_aws.qcn file from the AWS tutorial. Then when I flash MDJ modem from bell or the one from this dropbox link: https://www.dropbox.com/s/2m3id2cx4l...37MVLUAMDJ.zip
It still doesn't show my secret menu.
The secret menu I'm trying to access is the *#0011# but if that didn't work I also tried the *#9090# It still doesn't show the secret menu. So what do I do now? Please Help!
Thanks for reading!
Sorry to hear that, but you are in the same situation i was, the phone was probably sim-unlocked by Box Software, like Octopus or Z3X Boxes as i did, the phone won't recognize some sim cards by unknown reasons, there is no fix avaliable for this as i changed imei, tried different NVM from other phone & even replacing sim card reader. i finally sold it & got myself a i337m unlocked via code.
Edit:
forgot to mention, My SIM stopped being recognized when i upgraded it to a newer LTE version
Kind regards.
Have you tried stock NC1 with the included modem? If the device is unlocked, you might have better success with SIM recognition. In my case, my device was not unlocked, so I Odin flashed stock Telus MDJ, then rooted with CF-Auto-Root, unlocked with RegionlockAway (KNOX tripped), and applied the AWS Mod.
Then I flashed stock NC1 with the incl. modem (root gone), and managed to get Rogers LTE and Wind H+ on the Telus device. From there, I OTA updated, and rooted with CF-Auto-Root, flashed TWRP, and worked my way to 5.0.1. Trust me I know how frustrating this can be, but thanks to this forum, there was a solution. Here's what worked for me (link). Good luck.
Hi,
I have a Defy MB525 on T-Mobile running CM 7.2. The phone is getting old and has some hardware problems, so I bought a more gently used one on eBay. I've rooted the new one and successfully installed Bootmenu, 2ndInit, and CM 7.2, but when put my SIM card in it, it wants an unlock code. I tried the soft unlock method discussed here, but no success. I then tried the troubleshooting recommendation involving airplane mode and terminal emulator, but that didn't work either. I then got the idea to backup my "old" phone and restore it to the "new" one, and that went smoothly, *BUT* while I no longer get prompted for a SIM unlock code, there is an "x" next to the service bars and the phone indicates "no service." Both old and new phones have EPU93_U_00.59.01 baseband, old phone does get service, while new one does not. I'd love to hear any advice people may have. Oh, new phone was on Moviestar service . . . sorry for the stupid question, but when I've been prompted for a SIM unlock code is it Movistar's unlock code that I'm being prompted for or is it T-Mobile's? I assume that SIM unlock code is associated with the phone and not the particular SIM card itself--is that right?
Thanks,
Doug
I guess what you need to do is install Baseband switcher 4.1 or 4.0 and configure it so it grabs the correct baseband
So i have the smg935p but i am new to flashing roms and have been learning trial and error. I initially flashed a custom rom to the 9bit amd essentially soft bricked the phone. I did more research and flashed the stock rom(or so i thought) now my software version is G935AUCU8ARJ1. I have since had the phone unlocked by spint but now every sim i put into besides the original is showing invalid. Any ideas as ti what i can do about unlocking this phone to any carrier? I am currently using straight talk which i never wouldve switched if id known about the hotspot issue. Also if anyone knows how to bypass that issue that would also be wonderful. Can i perform this unlock or task of doing such without a computer?

If you previously owned it, you can try contacting Sprint to get it Sim unlocked. You might have better luck finding an unlock service on eBay though
Hello. Im trying to use my old k20 on a new network. The doner sim card fuctions fine on 3 other teat devices. However it is not unlocking from Metropcs. Its been in my drawer for a while and can not find the original sim card. Whwn i insert working sim there is no Sim card detected. The Device Unlock app states both Pass and Fail.. What am i missing?
I have this message too, it basically is saying that the unlock fail because you (or somebody else) have already unlocked the device and have applied it. I just unlocked mine because I had forgot that I can so I can sell it, it worked and was approved, so it restarted and when I checked to see what it would say again, it gave me the "Unlock failed, Unlocked approved" message. In all, the phone is unlocked, but idk why it will still show the Metro PCS start up, aswell with all the bloat.

Unlocking the device doesn't automatically remove carrier bloatware and other signage. That's what the stock ROM for the phone will be like when it's bought as carrier locked.
As for the OP question, if the SIM works on other devices but not your K20, and you're sure it's carrier unlocked, have you tried doing a factory reset with the SIM card inserted beforehand? It may just be the stock ROM being stubborn or stuck with previous config data.
Hi Everyone,
I just bought a brand new s10+ from marketplace. I ran a full imei report and everything is clean & not blacklisted. It was a sprint phone however the provider I use is consumer cellular (uses ATT towers). When I put my sim card in it obviously said invalid sim and request it get unlocked. I wasnt concerned because I was going to convert it to unlocked anyways via odin like I did my note 9. I reflashed it via odin with the u1 firmware. However the same thing is happening it keeps saying invalid sim and the button for mobile operators is not showing. I have a tmobile sim card and if I put that in it works fine. Being though tmobile and sprint are the same thats why it works fine. I also have a ATT sim card, If i put that in I get the same invalid sim message. So it still appears to be locked somehow. Only sprint / t mobile sim works. I thought by reflashing to unlocked it would unlock the phone sim.
Just to be clear the phone is brand new and never was attached to any account.
Any ideas? I dont know what to do here.
Thanks!!
As I understand, phones that are locked to a network are not just software branded... also the phones hardware ID. So flashing a generic firmware is not enough. You need to get the phone unlocked from the phone's original operator
I found out what I had to do. I had to use a remote unlock service to remove the software lock on the phone. Its fine now. Thanks
