Hi all long time user of the site but never been registered as never run into issues such as this below.
Recently family member took out sim of their locked three IE phone and tried to put another sim in into samsung j3 2016 sm-320FN model, one thing lead to another got message promoting for pin, even when original sim was put back in which never had pin lock on it and tried different pins which propably triggered some sort of lock on the phone but original sim works fine in any other unlocked phone.
When i took hold of phone i tried to root it and got hit with frp lock, eventually untied it from google account and managed to get lineage room onto it v14- no backup was made of original firmware my naive thinking on this part .
i used odin v3 with twrp 3 wiped cache david data and systems before hand. got it rooted with SUroot, and after then installed latest twrp to get other rooms onto phone.
Now strangest issue is that original sim works fine on any other unlocked phone but putting it into J3 i get hit with network unlock code PUK, at first tried support from three Ireland they thought it was sim blocked after numerous different codes it would return same message network unlock failed, eventually got hold of network unlock code, but entering it in lineage room OS it would say network unlock was successful but there would be no bars on sim, checking reception and signal it would show as none towers discovered and no signal received, following that every time phone is reboot it still promts for same code, figured it might caused issue with current room and downgraded to lineage v13 but still wouldnt see any reception the signal bar appears grey, final conclusion was maybe wrong unlock code was sent so requested another one which came back same as previous from mobile provider.And all repeats if entering code says unlock is successful but no mobile signal detected, tried 3 different roms and always keep getting greyd out signal icon and promt to enter puc unlock code.
In the process managed to wipe completely all rooms from the phone and did DBA backup restore via cmd and managed to get different room running on it RR-OS but same happens each time phone powered up inserting any sim including original network sim promts for code, after entering it, says successful and no bars or signal.
phone is only good to use for wifi browsing now, and im out of options to figure out whats the main reason also cant find original firmware.
Spent 2 days flashing rooms and unbricking phone but seems mobile signal and network unlock fails for unknown reasons to me. tried to list every step ive taken and software used.
If anyone has any idea whats causing this would appreciate any help, even thou phone is old by now but still enough for person that uses it.

Hi guys,
I recently picked up a used S4 on Craigslist for cheap because the guy "screwed up" using Odin and flashed something that caused his phone to not register on any networks. I figured, what the hell, it's cheap enough and I might be able to restore it. So far I've restored the Rogers firmware over Odin and tried installing a custom rom/recovery too. I'm still getting this problem unfortunately. The IMEI reported with *#06# and in the status screen does match the sticker on the inside of the phone.
So I'm sure everyone's going to suggest that the phone was stolen and the IMEI has been blacklisted. My provider (Fido/Rogers) apparently doesn't care if the IMEI is blacklisted, they'll let it run anyway. I called up Fido anyway (since I'm a Fido customer) and asked them about the IMEI of this phone and they say they don't have any record of anyone calling in reporting it stolen and they don't have an IMEI database so she didn't have much to say about it.
Does anyone have any other suggestions? I've also flashed just the kernel, and I will flash a modem onto it too. I know my SIM card works, and both my SIM card and the last owners SIM cards don't work. I know the radio works because it picks up the emergency signal fine, and the SIM tray isn't damaged because when I put in my Fido SIM the Fido APN's automatically come up, as well as the lock screen goes from "No SIM inserted" to "unregistered SIM." Could my EFS partition be borked? Wifi works and IMEI shows up correctly.
The buyer said he would take the phone back if I can't fix it, but I want to try a bit more before I give up. If anyone has any ideas or suggestions, that would be great. Thanks a lot in advance XDA!
Summary:
-Used S4
-Owner flashed something wrong in Odin
-Gets "Not registered to network" error, unregistered SIM error
-Tried restoring
-Tried new ROM/Recovery
-Carrier says IMEI is fine, also tried directly registering the IMEI to my account
-IMEI is correct in settings/sticker on back of phone
-Wifi/everything else all works
Sounds like it's SIM locked to a different network. Try the the guide here: http://forum.xda-developers.com/showthread.php?t=2285431

My girlfriend has a Bell sim, which when we insert, gives us the "Please enter unlock code" screen.
My sim does not do that. I know this device is for my carrier, but I figure the easiest way to get this going is to just unlock it and see if the problem persists on other networks.
I've tried that unlock tutorial before. The first time I tried it, when I just got the phone from the previous owner, it said "Golden-backup does not exist" so I couldn't do the restore step of that guide. After Odin-flashing everything and starting over, I can't even get into the UMTS menu anymore! I'll try another restore and give it another go though.
Edit: Another problem. I did a restore again using Odin and notices that it never properly wipes the phone. When I finish flashing, my Wifi still autoconnects on first boot, and every few seconds, a process crashes causing the phone to freeze. Has anyone heard of this kind of problem before?
Quick update:
Managed to Odin-flash it to the earliest firmware I could find for the phone without any crashing or freezing problems. Trying to do the network unlock method mentioned online. It does not work, even though I'm following the instructions to a T. Could it be that my EFS partition is borked and that the NV rebuild can't happen, meaning my radio configuration would also be borked?
Edit: Oh and when I booted up my phone for the first time, the phone was actually ON Fido! But within a few seconds, it went back to "Emergency calls only."
Hmm, that is some odd behavior, and definitely not a carrier lock. Shame it's never that simple to fix.
Not quite the same as your issue, but I lost my ability to make and receive calls after flashing a newer modem on an AOSP firmware. Flashing custom kernels, older modems, the latest stock rom and kernel were no help at all. I tried everything I could think of short of groveling. In the end the only way I got everything working again was to flash the original factory firmware my phone shipped with, factory wipe it from stock recovery, then flash it again. If you've already tried that (and I'm guessing you have), consider contacting Samsung regarding warranty. They've been really good to me in the past, even with second-hand phones.
I can confirm that Odin doesn't clean everything out. In my trials I also noticed that flashing via ODIN without a factory reset presented no setup wizard, caused lots of FC's and left some previous files hanging around.
Sounds like a bad sim tray.

I had trouble with my handset after it got run over in the street, making it's otterbox earn it's money. The only bad symptom after that episode was Emergency calls only kept recurring.
I cut a tiny square of transparent scotch tape, avoided touching the sticky side, and placed it squarely on the SIM chip's backside, to make it fit the sim slot more snugly. It sounds like you should try stacking two or three layers on your chip as it sounds to be more loose than mine is.
Hi everybody! Thanks for all the help trying to fix it! It ended up being that the guys the previous owner had unlock it used the debug-menu unlock method and my phone was one of the ones that doesn't accept it. Lots of other people complained about similar problems as me in the free unlock method thread. In the end, I paid for the FastGSM USB Unlock method and it fixed the problem.
OH MY GOSH YOU JUST SAVED ME from buying another phone!! THANKS so much.. I added 3 layers of tape on the back of my sim and it works!!! weird.. cause I have the Dual Sim.. and it was the first sim that would not work. the second sim was fine.. anyways.. THANKS SO MUCH!!
This is going to be embarrasing story.
I bought new Nexus 6p, and it required Nano Sim card. Being genious me, i've decided to cut my old card and insert it in the sim tray.
It did not work and asked me for sim card's PIN code (which i never set up). Figuring i must have simply broken the card, i decided to boot the phone without any card inside.
Now, when i start the phone, i get the same lockscreen right after Android Logo.
I have tried factory reset, and inserting brand new nano card from different carrier, but none of those it did work.
Using the emergency call dialler I tried entering PUK code *05PUKnewPIN*newPIN# and i recieve "Connection problem or invalid mmi code" error, with or without nano sim card.
Most of the fixes for MMI error are assuming that user can successfuly launch the phone as well.
I have yet to try putting "," or "+" somewhere in the USSD code, this is supposed to "ignore any error messages and perform the code" but i am slightly pessimistic about this.
I thought that maybe the pins were damaged, but they all seem to be allright.
I am a bit conflicted about flashing the image, since i am not sure if unlocking and locking bootloader for flashing will impact my warranty?
I have tried already flashing 6.0.1 stock on top of the stock 6.0.0 the phone came with, but I was still unsuccessful, since i did not enable USB Debugging on the phone and when performing flash-all command in ADB fails due to locked bootloader (that can be unlocked from the settings).
Tried fastboot flash unlock (since fastboot oem unlock did not work at all) as well but it did not work for me.
Based on this, those are the possibilites i consider:
*Try to get MMI error code fixed
*Flash the stock android once i get around locked bootloader
*check the SIM card slot for any dents on pins
*contact carrier and check if maybe it was somehow locked on their side
*Return the phone on warranty and hope that it will be accepted (i expect major hurdles along the way, since the phone was imported to Poland), this would imply that i should not interfere in hardware and software.
I feel that if i get one of mentioned above issues, rest of them should be a walk in the park.
I am really looking for feedback from you guys, since i seem to be unable to deal with on my own.
EDIT: Solved! Found an official google nexus helpline (support.google.com/store/answer/6301411?hl=en) from there someone contacted me and i was given directions on how to solve this issue. If someone finds this thread i needed to do another factory reset
Hi guys
I recently purchased an S4 from an on-line professional seller, the guy apparently owns a physical store but sells some phones on-line
when the phone arrived, I turned it on without the SIM, insert my home's wi-fi connection password, and the phone started to update both apps, and the OS to lollipop
I installed the backup I previously got from my old s3 mini, installed all my apps from playstore, and once I installed whatsapp, I turned the phone off, and than on again, this with my SIM since whatsapp has to confirm my number
The phone accepted my PIN code, whatsapp accepted my number and restored it's backup, but the phone also asked for this SIM network unlock pin
I told the guy what's happening, he told me he would send me a new phone, but I suspect this can go wrong
If that's the case, can anyone here tell me how can I overcome this SIM network unlock pin issue ?
thanks in advance
Regards
Antonio
If the phone were unlocked for use on any carrier, you would never see the SIM unlock pin request screen. Since you are seeing that screen, the phone is not unlocked.
To resolve this, root your phone and downgrade the phone's modem to an Android 4.2.2 version. Find a copy of RegionLock Away on XDA or through Google, copy it to your S4 and install it. Run it. Afterward, upgrade the modem to a more current version, and enjoy.
That's roughly what I had to do when the SIM unlock screen popped up on me.
Which s4 do you have? If it is the i337, region lock away may not work as you may not be able to downgrade the modem.
Hello guys.
Recently, my phone's EFS files & IMEI got lost. I managed to "recover" my phone from its unusable state, but my phone refuses to detect the SIM.
My IMEI was 0, but I changed it back to my original IMEI. Yet my SIM still does not work.
The SIM itself works on another phone.
EDIT: It also seems that the SIM is indeed getting detected on my Mi A1, but no mobile network, and messages/calls do not reach me.
For the full story:
I flashed a MIUI 12 GSI (Android 9). Then, wanting to try out an A11 custom ROM, I flashed it, like I usually did.
It took extraordinarily long to load, so I force shut it down (this probably corrupted my EFS and stuff) and from then on no ROMs would work, and TWRP would give me a black screen, and a myriad of other problems
After 2 days of non-stop research, anxiety and magic I managed to "fix" my phone. The SIM was working at some point, but along the process it lost its IMEI, and even though I managed to restore it, the SIM does not get detected at all.
I would appreciate any help at all. Thanks for reading.
Hi Folks,
I have a VNS-L31 running C440B392, EMUI 5.0.4
It is UK region and currently locked to EE, or sort of. I have the unlock code from EE, no problems getting that but when I put in different SIM cards I'm not given the prompt to unlock the phone. The phone boots and tries to connect but then fails to register on the network.
Oddly, if I boot the phone, put in an EE SIM and allow it to connect, then swap the SIM to another network without rebooting it will connect to the alternate network for a short while.
I've been looking at the instructions for putting custom firmware on but most of the links are old and dead. Even trying to find copies of the stock ROM doesn't do well these days as the Huawei database is gone.
So, I'm not sure where I am with it other than waiting for a response from EE that may or may not help.
Factory reset makes no difference...
It's a lot of hassle to go to for a backup phone!
Cheers.
