New g955u won't connect to Verizon - Samsung Galaxy S8+ Questions & Answers

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.

S6 g920v - Locked out of my own phone and cant gain access. Radio off?

Ive read other posts and searched the web but I can't figure out what I'm doing wrong.
I have an old s6 I was about to sell so I downloaded the official 7.0 from samfirm and started installing via Odin. At a certain point in system.bin it freezes for 30 minutes. I pull the plug on it. I'm supposed to meet the guy in 2 hours at that point and I download multiple different vwz firmware for the s6 and eventually am able to boot up again. The problem now is that a stock firmware won't completely work (modem.bin) and the older versions from updato work except for system.bin.
So now I have access to my phone but when I go to login its samsung account locked. I try to type in my username and pass and it says "Invalid ID or password" and I even reset it but it still says invalid. I can see the phone on my "samsung wheres my device" website, but I cannot unlock it because it says radio is off.
Edit: Forgot to mention I tried to update from 6.0 to 7.0. Tried multiple 7.0 firmware and attempted to revert back to 6.0.1. I honestly don't know what firmware i'm on now.
It says im on FA50_g920vru4AOJ2.
I'm in the US.
So im wondering since i've frankensteined these firmwares together, is this radio issue because I've flashed a different vzw modem? When it's plugged into my PC it says device not supported. When do a factory reset I assumed it reset the modem back to factory as well.
I can post pictures if need be of the phone showing up in my samsung account so you don't think I'm doing something shady.

Samsung Galaxy S10 (SM-G973F) doesn't register to network

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

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.

Stuck in a loop between custom binary blocked and downloading do not turn off

I turned off and then restarted the developer's mode in my S7 yesterday. When I went to turn it on today, I got the message "Custom binary blocked by FRP Lock. I used power / start / vol down holding all three and came to a screen that wanted to know if I wanted to download (probably Odin). I then pushed two buttons of which one was the start button (the one in the middle of the bottom) and the vol up button, which started the phone trying to download. It got the message Downloading "Do not turn off target". I figured out how to stop that, but when the phone rebooted, it was back to "Custom binary Blocked ..."
The information I need to download firmware (like the CSC), is either in my phone or not common enough to exist in the country lists with their respective phone companies. My phone is an S7 and probably a G930F, although I can't verify that because I can't get into the phone. I would not mind downloading Odin, but I understand that the information regarding CSC_home with regard to who my provider is and what country I'm in is necessary in order to install Odin and I don't know how to find that information or to find the complete model number for the phone.
Thank you for any advice you can give me. I would prefer not to have to use a factory reset on the phone to get it up and running again.
Changing OEM Lock does trigger FRP sometimes, like 2 years ago my friend had the same on his Note5, it wasn't that hard to solve.
You need to verify your device model (written in the download mode's top left corner), then download a recent firmware, flash it via Odin, after booting, it'll ask you about your Google account and in some cases, your Samsung account, too.
Unless you've forgotten them, you should be good.

Thanks very much. I got the info off the download screen.
Do you mean I should go ahead and download Odin and then hope to find the right firmware? That's giving me part of the problem. I downloaded two different versions of Odin
3_v3.11.1
3_v3.12.3
I think to get the right firmware, I would need to know the country 3-letter code, if the phone is dual sim or not and the service provider? Since my service provider is not among those listed (like telekom or O2), can I use "unbranded" for my country? Or is this information for the CSC entry something my provider could provide?
Also, if I enter that into CSC, will I still have the option for Home_CSC? I'm quite interested in trying to keep my data.
And finally, I don't think I set up any account which had to do with the cloud. If an account was needed to verify the operating system, then I hope to be able to figure out what that was.

It doesn't matter. Any firmware will get your phone booting, that's the point, if it was FRP cause you forgot the Google account, then perhaps you should be picky, but since you're not, then it's fine.
CSC gets activated when the phone detects your SIM card, that's how it knows where you are and that's how it sets CSC features provided for your region. If you pulled the SIM out, it won't apply CSC just yet. If you travelled to another country, your CSC will be changed (once you boot into recovery).
What model your phone has, so I can find you some files?

I'm making some progress. I learned you can get the model number off of the recovery screen which I got to with power / vol up / Home and by waiting for the Recovery screen to appear.
I then found a very close firmware in updato, but the last letter was a y instead of a c, so not the perfect model-number-match. That one with the wrong last letter was for my region in the EU. The actual matching firmware ends with a c and I found that firmware on multiple websites, but listed as being from Thailand.
Now, the strange thing is that I bought the phone in Germany for a trip to Thailand and got it unlocked before I went there. Since I'm in Germany and most likely Telekom, and since I've read to trust no website except Updato, which doesn't have the firmware for my exact model number, I've been wondering how to proceed?
You asked for my model numberOne of the non-Updato websites offers the firmware with a checksum with the file, but since updato doesn't have that firmware file, I couldn't know if the checksum was the right one.
So I think what you asked for was the model which is G930FXXU1DQHC
Thanks very much.

That's a very old firmware, it has U1, latest has U8, I had the same device, too.
A trusted, reliable site would be AFH, search for G930F and find large files, that's the firmware.
Hi,
I found the big file of 1.8 gb called G930FXXU1DQHC_DevBase_v4.3.zip and downloaded it and extracted it to a folder I created myself called odin. It's not what I was expecting. It is a whole lot of folders within folders within folders, but none of the files that I would expect to be able to click on for an installation by odin. I was actually expecting three files that were clickable, which I've seen in instructions that utilize Odin to flash the firmware.
The two main folders it produced were ALEXNDR and META-INF. There's a single file at the same level as these two folders called options.prop.
Edit, I will try to attach a screen shot of what I was expecting to get.
More Edit: I'm not finding an installation file, so I think I'm at the point where I need to install Odin, but I don't know whether I install it on my pc or on my phone and if I should install that before I install the firmware. That's the point, isn't it? That Odin is in place to install the firmware?
Also, I can't see any exe files in the zip file I extracted, so I don't know what could be installed.
What is it I should be looking for?
Thank you. You're helping me keep going.
I see you did not get what U1 and U8 means. For an example, this is the latest firmware for Galaxy S7.
But, you downloaded a U1 firmware, which is very old to be believed. Forget about that, download this one, extract it, and flash it via Odin.
Thank you for that information.
The short version: I'm back in! All the stuff below is my journey which was rocky. Had to do some more internet searches, which brought me to another thread here in the forum:
Can't flash firmware, RQT Closed.
Hi! I need help, I was trying to flash Indian firmware (latest) on my Note8 (N950FD) with french rom. But when tried to flash the rom with Odin, start the procces and less than a minute, finished and appears as success, but nothing happened...
forum.xda-developers.com
For others who come after me:
I downloaded the firmware files, started Odin, put the phone in download mode (power / vol down / home), then plugged the phone into the computer and clicked on the boxes one at a time in Odin and was directed to firmware files in Windows Explorer and clicked on the correct one. I wanted to save my data so in the box called Userdata, I entered the CSC_Home file. They were all accepted. Then I clicked on Start in Odin and after a short time, the scrolling of files on the left side ended. That's where the above link comes in which says to try using a more recent Odin, so I tried again with Odin 3.13.1 (with the Chinese figures).
This attempt went better, took longer and then my phone sat and blinked Samsung at me for a very long time. I finally turned Odin off with Exit and then waited some more while the phone was still plugged into the computer. Then it started installing what it had downloaded. At least by now the little Android robot wasn't keeling over anymore.
After that finished, it asked for my pin and accepted it and I got back to the home screen. It then asked if this was my phone number, which it was. And I could see! that it had a charge of 44%.
I then went into Settings and looked for the developers setting and found that OEM was indeed turned off and that probably caused the FRP lock to occur. I turned the developers setting off for now.
I was able to keep my data with one annoyance. Some of the less standard apps are giving me a pop-up when I open them that says the apps are always on, do I want to close them, and there's a feedback button which simply shuts the popup off. You have to keep turning this off. It seems to affect non-standard apps, so I may have to reinstall those. I'll look into that ... tomorrow.
Many many thanks! It was so great to find someone who knew how to help me! I really appreciate it.

Question Samsung S21 VZN need unlocked or converted to ATT. Tried odin.. Maybe I am an idiot.

Hello.
Got a free phone from a buddy S21 5G. I am wanting to swap it for the S10* 1tb I gave my wife to use it was a bit expensive. So I'd rather ti go back in the box.
Popped the sim in it, it works makes calls sometimes, sometimes not. Texts seem to always work, I am currently on ATT I would prefer to have that firmware as I live in the stick with ho cell service. ATT has wifi calling which is pretty much a necessity here.
So what exactly do I need to do to get this off the VZN fir
Hello. Could you all provide me the links for what I need? Found a link that had a patched Odin plus the firmware. I installed in booted how I was suppose to. Tried to install in and it errored out. Also. I do not know what file to select for the user data selection, I do not mind deleting all data as it 8s hacked up and can put ti back with smart switch.
Hello, did you manage to flash the phone?, I'm stuck with a similar case, mine is a factory unlocked unit from Verizon, it turns out that even if it is factory unlocked, is locked after a few minutes by verizon, I have tried everything to get rid of the VZW firmware but it seems that Verizon locks the bootloader so I can't flash it (it passes om odin and everything but the firmware doesn't change)
I even paid SamKEY credits to change the CSC but it didn't change either.

How do I fix "invalid IMEI" in my android phone? After factory resetting, it says "IMEI is empty."

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.
