Hi everybody,
my S7 doesn't want to turn on WiFi anymore, and don't know why. Checking my software version in searching for a clue, I tapped update OS and got the message that my OS was modified without authorization. I rooted some other smartphones in my earlier years (HTC) but not this one, I just have it for some 6 weeks. Did something like that occur to anyone of you?
I attached a screenshot of my softwareinfo if it helps.
Thank you in advance for any hint.
Might Be a software bug, try factory resetting. The important thing is that KNOX isn't tripped, you could always bring it to a Samsung Store and let them update it for free.
Y just try factory reset or installing a stock rom with odin again otherwhise go back to the store!
goodluck!
I did factory reset, and the problem was gone - for a short while. I also switched off auto update of fear of wrong OTA updates. Now, my OS doesn't appear as unauthorized altered. But the moment I inserted the second SIM (sorry, forgot to mention it's the dual SIM Version) the initial problem reappeard: No wifi connectivity. Is the wifi module located near the SIM Slots?
Cause of error found
Just wanted to inform you, that I succeeded in finding the source of wifi error: Using the second SIM slot (only with SIM, SD card working fine) disables wifi. Why exactly, I couldn't find out though... Anyone experienced something similar?

I bought this device less than a month ago from the carphone house when I was in uk. Today it gave me no sim card error suddenly. the device is not modified not flashed. I did nothing to it. I tried reseting the device but still having the same problem. I tried a different sim but had the same problem.
However, what I did notice that the device ask for the PIN of the sim card but as soon as I enter it. it gives me no sim card error
Any suggestion well be hopeful. Sadly I also lost the receipt
Are you using Agile Lock or any other lock or launcher app?

Thanks for your help but I was not using anything adding to that I did restore the device to its factory settings I did a complete (hard) rest for the device but still facing the same problem
I think I should have expected such a bad quality from LG
Anybody Help
Please anything
Hi, i had the same problem a few days ago, but on another situation.My phone was rooted and i tried to install "original firmware" to get rid of CWM and root, but at 42% of the process"Windows just crashed the LG updater", i managed to restore my old ROM trought CWM but got a sim card error, everything else was working but telephony.
Just tried it again like on this simple tutorial and got the original firmware installed again, and for my surprise telephony was back.
If you lost you receipt and dont live where you bought your phone, maybe this is what you can try.

I'm about ready to throw this phone out the window, and hoping someone here can help me out...
My wife ordered a never used g955u off of ebay. It came with Oreo installed. It had the CRE9 firmware installed. We are on Page Plus (Verizon reseller). We put in her SIM card, went through setup, but we are not able to make phone calls. The SIM card works fine on her old phone. I reset the network settings to no avail.
I did a network search and selected Verizon Wireless, but it times out and gives the error :
No Service
Selected network (Verizon Wireless) not available
I talked to Page Plus, and everything looks fine on their end, they say it's something in the phone.
I suspect it's something in the radio settings, but I'm locked out of the service menu. I factory reset the phone, and that didn't fix it either.
I've been down several rabbit holes since then.
I tried to follow the steps in this thread: https://forum.xda-developers.com/galaxy-s8+/how-to/carrier-switch-snapdragon-t3615680 hoping that if they can make non-verizon phones work on verizon, then it can make a verizon phone work on verizon. I also tried to root the phone using this thread: https://forum.xda-developers.com/ga...root-g955u-g955u1-snapdragon-sampwnd-t3658911 hoping to get access to the service menu.
But evertime I tried to flash any of the necessary binaries, I got Fail! (auth) and the phone gave the error:
sw rev check fail : [boot]Fused 3 > Binary 1
or
sw rev check fail : [boot]Fused 2 > Binary 1
Turns out, you can't downgrade. And all the binaries in the tutorials are now downgrades.
Somehow in all this, I managed to flash the phone to CRD4. I tried flashing back to CRE9, but regular Odin fails without telling me what the error is, and Comsy Odin gives a model dismatch fail.
I tried connecting the phone to Kies, but it gives me the error "only the device owner can connect to kies" even though I'm running Kies as administrator.
I've ordered a new SIM card from PP, just in case that fixes it, but I'm losing hope here. If anyone can help me out here, I'd really appreciate it. If there's anymore information you need, let me know and I'll post it.

Yeah, that's what I had figured out. I'm still not sure what direction I need to go in to find a fix for this.

So I know Odin 3.13 at least. But other than that with Oreo I don't know
I wanted to stop by and mention I am having nearly the identical issues. I bought a used Verizon Galaxy S8 from somebody today, and even ensured that the IMEI was supported by Page Plus beforehand. I tried using an existing, working SIM card of mine from Page Plus but found that it did not work automatically as it should have. After going through four customer service representatives, I was told that my phone is somehow not compatible. Still, I think I may have a slightly different situation going on... I was told it would not work because there is no "LTE/CDMA" option in the "Network Mode" setting. Instead, upon inserting the existing SIM into the new phone, my Network Mode setting only has access to "LTE/3G/2G (auto connect)", "3G/2G (auto connect)", "3g Only", "2G Only" options.
When I put the SIM back into my working phone, it gives me the correct network options. For some reason, this new phone is not allowing me to connect to the Verizon network at all.
You've taken a lot more steps than I have... I figured it could be an issue with Android Oreo, but I am really not looking to delve into the degrading process. I will also order a new SIM and see if that magically fixes things, but it's starting to look like a lost cause.
Let me know if you figure something out - you are the ONLY person online I have found with my identical (or near identical) issues. If you happen to know any way around the exact issue I'm having with the Network Mode, that would be insanely cool.
Hello guys,
I am losing my mind here so I kindly ask for help. I aint no expert in flashing roms or anything, I have a stock Redmi 6 and yesterday I got a pop up about updating my phone. I selected yes and my nightmare begins.
Since then, I cant get the phone to connect via mobile network. I cant get any connectivity of any type using mobile data.
The phone is a Redmi 6, android version is 8.1.0 O11019 and rom is MIUI Global 10.2 Stable 10.2.3.0 (OCGMIXM).
Please help the noob get his phone back, I am about to throw it away
There is an update miui_HM6Global_V10.2.4.0.OCGMIXM_f662ddbe15_8.1.zip
http://ru.miui.com/thread-24171-1-1.html
thanks for your reply, updating to 10.2.4.0.OCGMIXM didnt resolve the issue.
Still no 4G.
Any other ideas? Please I am desperate
Head to" about phone" (in settings ) tap " internal storage " multiple times to enter phone info
Then head over to change network settings to LTE only or enable one with LTE as a possible option if you've disabled it by mistake
Also check which slot your sim is in ...
May not work if sim is in secondary slot and 4g is disabled for it
Let me know if it worked !
Cheers !
Thank you for your reply my friend.
I have tried all these things, they were the obvious ones, so I went with them first. Nothing works, phone is unable to connect to 4G. I have flashed multiple times in case it was a bad flash, I even downgraded to a Developers Rom, but nothing works.
Funniest thing of all, I contacted Xiaomi UK customer services today, and after trying various *# codes, and the guy asking me to turn the phone off and then on again, he ended up saying that I need to wait for the next update.
It is insane
I recently bought a used Samsung Galaxy S10 (SM-G973F).
At first glance the phone was in excelent shape. The SIM Card was connecting to the mobile network, and calls, internet connection, etc was OK.
But then, I found out that the phone had been rooted. Probably, by the seller. In pannic, I rushed to unroot flashing the stock Rom.
Here what I did:
1- Forgot to check my precisly CSC code and assumed ZTA (cause I'm from Brazil, and the phone is from carrier "Claro")
2- Downloaded the stock rom using Frija
3- Using Odin 3.14.1 flashed the device.
The previous rooted system was on Android 10 and One UI 2.5. With this new rom went to Android 11 and One UI 3.0.
The problem:
The phone recognizes the SIM Card. But it simply doesn't connect to the network. When I try to make a call it says: " not registered on network"
The phone DO recgonizes the SIM Card. On the SIM Card Manager shows my carrier name (Vivo) and my phone number. Also, the SIM app is showing on the app list.
Things I tried:
Rebooting the phone
Changin the SIM Slot
Testing the SIM on another device to ensure it was working
Checked if the IMEI wasn't missing/undefined. It is not, the IMEI appears to be untouched
Checked if the IMEI had been blacklisted. It's not.
Flashed SEVERAL different stock ROMS with different CSC (ZTO, ZTA, ZVV)
Try to manually select the network. This also throws an error saying "error while searching for network"
I'm really desperate and don't know what to do anymore.
No one have a clue either? :C
Look inside here:
How to Fix 'Not Registered on Network' on Android
Here is how to fix 'Not Registered On Network' error on Android. Mostly error occurs on Samsung phones, but this solution works for all android phones.
www.android-recovery.net
Wow,
This is exactly like my S10 right now.
At first, all is good, the signal was great, all working well, except cant connect to samsung pass and samsung health because it was root.
then i brought to sellular shop service, to flash the phone.
Then, “not registered to network” happened. The signal ok, the phone able to read dual simcard, but “emergency call only” and if i try to search network manually, “error while searching for network”
And the sellular shop service have no idea how to fix after they reflashed and try to fix it for several days.
Have you found any solution to fix your pho?
pls advice…

So, were you able to find a solution for this problem? I also bought a Note 9 N960F/DS recently and found out it was actually a N960N model that was changed to N960F/DS. So I did exactly what you did, I flashed the original stock rom, N960N, but now phone will not connect to network. I also did hard reset, reflash other stock roms, nothing changed. Anybody with insight should please give us some pointers.
I have a samsung a12. It was rooted and I tried to software update it with odin, but failed and led me to factory resetting the phone. After it was done, for some reason it said "IMEI(or MEID) is empty".
I think it has something to do with my sim card? But I have it inside already and tried putting it out and back in but no success... Now I rooted my device again and tried a lot of stuff but nothing worked. Any suggestions?
IMEI has nothing to do with SIM-card:
IMEI stands for International Mobile Equipment Identity and helps identify a specific phone across all mobile networks. Think of it as a social security number for your phone, or a fingerprint. It’s a 15-17 digit number that allows networks to identify a phone and get information on what kind of phone it is, including where it was manufactured and its model.

I'm having the same problem with my factory unlocked USA version S22 Ultra running on T-Mobile. Seems like it started right after I applied the June security update over the air. Whenever I try to access my Samsung account or Find my mobile in Settings, or use the Galaxy Store app, I get that exact same message. Did you ever find a solution to it?

I'm also having the same problem on my factory unlocked USA version S22 Ultra running on T-Mobile. I deleted my eSIM and got it reactivated and was able to sign back into my Samsung account, but the problem came back when I restarted my phone.
I posted the following thread and got the help I needed to solve my problem. Hope it helps you too.
