Hello,
i just got an old a5, the 2015 variant.
I was told it was from an colleague who wanted to throw it away since she wasnt able to surpass her mcafee security stuff and now its mine.
i made a wipe to factory settings and unsurprisingly, i got a clean phone. but it didnt recognize my sim.
so i tried loading the current lineageos on it, su it and everything worked. well..everything except for the sim.
i tried the last two days to get it running but to no avail. tried normal stock rom, older lineage, current lineage, some modem fixes i found here, nothing works. and im nearing the point of just throwing it away^^. samsung phone info leaves most of the csc-code field plank and in settings, i get invalid network mode (-1) in the networks section
Can anyone help me (or the mobile)?
solved it myself. for those who care: i put some ducktape on the back of the nano sim and carefully (theres more pressure on the card and holder) put the whole construction into the sim slot 1.
Even though noone answered id like to thank anyone who cared.

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
Hey there!
I try to keep it short. I have no network service (the sim is working in other phones). There is sometimes a "stop" like symbol in the top bar or an exclamation mark saying "no chosen network available". However, emergency calls should be possible (phone got network access).
I bought the phone, so it's used and that "problem" was known. I thought I could fix it. I tried the following:
Rooting and RegionLockAway.
Flashing new Firmware (I9505XXUHOA7)
Flashing the ME2 modem and trying to SIM-Unlock it. However I get an popup "error" after pressing NV-Rebuild (it stated Golden Backup exists) and then the phone immediately reboots.
SIM detection seems to work (asks for PIN and notifies on empty sim)
The IMEI is there.
If I try to choose networks it gets a list with EPlus, T-Mobile and Vodafone (I am currently in Germany). Unfortunately I do not know where the phone's from.
Also, I never experienced any popups asking for unlock codes or similar - it is just not able to register on the network.
How can I make sure theres no SIM Lock?
How can I make sure theres no Netlock?
After those two are clear what else could be done? What about NVData?
Anyone any ideas? Thanks!
I can post some infos from the service/UMTS menu, however I am not sure which. I also searched and tried hours but without success.
Replace the SIM card tray. From appearances yours is dying.
Thanks for the reply. Can I test this somehow? I am just wondering since it asks for SIM-PIN and even reads APN data etc. I just searched and it is about 10 bucks on ebay and I should be able to do it at home that would be cool. So since it is detecting my SIM can I test somehow whether there could be other problems causing this problem bevore I try to replace that sim-slot?
Thank you!
By the way: Yesterday I also tried to repair NVData with the SamsungUnlock software as posted somewhere here. While that worked without a problem it did not change anything.
To sim unlock the phone, you could try flashing the 4.2.2 modem, rooting, and using regionlockaway.

I wish there was a way to test it. I only knew mine was bad by sheer luck. Mine revealed itself only after flashing an Android 4.2.2 stock ROM; more current versions didn't show anything.
Could there be a loose connection inside the phone?
Where it is a known issue, there is a possibility that the original owner replaced the SIM tray. When they did, they likely forgot to reuse the foam pad from the top of the connector on the old tray. If that pad is missing the connector will pop up in time.
hey thanks for your help!
I will open the phone and check the connector of the SIM-Tray. But as I already described, it even asks me for the SIM-Pin, but maybe even though something might not be right.
Regarding flashing an 4.4.2 Modem: Is that the "9505_DXUAME2_MODEM.rar"? If, I tried that already (installed that modem, rooted, RegionLockAway and even with the Serive Menu SHA256 OFF method (this one did not work since I got an Error and the phone did not freeze etc.). However, I did not install a full 4.4.2. Stock Rom yet.
Well maybe I could buy a SIM Tray and just connect the PIN without acutally gluing it on the phone. This way I might be able to get a refund if this does not do the trick.
If all these fail I just have to find some new use for that phone
You cannot use an Android 4.4.2 modem or ROM to unlock. The modem or ROM MUST be from Android 4.2.2 or RegionLock Away will not work.
Regarding the SIM tray, foam mounting tape from the local store on top of the connector will work. No need of glue.
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 all,
I have a problem with my XC, i hope there's someone here who could help me out with this .
I get a SIM card error when i start the phone. After a while (5-10 mins) the error transforms into "No Service" as if the phone now detects the SIM card but has no service whatsoever.
Things i did to my phone prior to this:
- unlocked bootloader
- installed custom recovery
- root
- installed custom ROM
- drm fix
The phone did function properly for a few months actually after these operations without a SIM card error even once. But then i tried to install custom ROMs again (and i'm sure didn't flash ROMs not suited for XC) -actually tried to install "existenz" ROM but i did get a bootloop so i -once again- did the usual procedure with flashtool and flashed a firmware to set everything back to stock as close as possible. That was, when i started to get the SIM card errors. After several restarts (cold and warm) the phone sometimes recognized the SIM card and i could use the phone normally. But this was true only till the next restart, where i got the same SIM errors again.
Things i tried:
- flashed several different firmwares (official) with flashtool (wiping everything) - all the newest firmwares.
- *#*#72786#*#* in dialer to wipe carrier settings
- *#*#4636#*#* in dialer to go into phone settings and changing those settings randomly
- flashed another AOSP based custom ROM instead of stock sony
- wiping and formatting everything between the flashes of course
- cleaning and re-inserting SIM card (which i never took out before anyway)
But unfortunately nothing worked. Phone keeps to not recognizing the SIM card (which is working just fine in another phone). Everything else works just fine on the phone. The IMEI is displaying correct. I'm almost certain that the fault isn't hardware-based (i didn't drop the phone or exposed in water etc.) but software-based. Did i just managed to brick my phone by flashing something related to the modem which i'm not aware of?
I can't find any solutions on google, which help me, which is why i'm posting it here. Sorry for the long post.
Did anyone experience such an error and/or knows what else i could try to fix this? I hope for answers
Thanks in advance!
Anyone?
I've got the same problem.
I didn't unlock the bootloader or anything prior to getting the bug.
I wanted to downgrade to nougat, because aparently it helped someone in the forum below, but I didn't manage to do it.
https:// de.ifixit. com/Antworten/Ansehen/468864/Sim+Card+not+picking+up+mobile+network.+Possible+software+issue+(Oreo)
Did you try nougat, when flashing different firmwares?
Your post makes me question if its worth it, trying to downgrade.
Try to remove sd card if you have one. then restart the phone and see if sim card is recognized.
I had the same problem and I think it was a hardware failure in the end.
I also tried almost all the things you were writing above. In my phone it started slowly. Sometimes the SIM was detected but after some time the connection was lost.
It happened some time after I installed a new battery.
But since there are no original batteries available for the device anymore and the new battery was even worse than the 5 year old original battery, I gave up investigating the SIM issue and don't use the phone any longer.
I bought a new (used) x compact because I still like the size and I saw some development was going on for this device.
In the end I cannot tell whether the SIM was not detected because I broke something while changing the battery or due to age of the phone but I think it was a "normal" failure.
I also read from others that they had the problem and the SIM was working for some time after I switched the battery before it stopped working.
Nevertheless. Good Luck to you. Maybe it is something different on your phone.
