I have a Verizon Galaxy S4 which has a fully unlocked bootloader and is rooted. On "My Verizon" the device shows up as unknown which makes sense. My issue is that I can't port my number from a Verizon Post Paid account to a PrePaid account since they can't active an unknown device on prepaid.
My question is, what on the Verizon system indicates it is an unknown device? Is it the bootloader? Rooted? Is there a way to revert back to a state that does not require relocking the bootloader that will make Verizon detect my phone as a Galaxy S4? I'm trying to switch my account over so that when my Nexus 6 comes in I can just swap at the sim card. Then the unlocked bootloader S4 goes up on Swappa.
Let me know if you think there's something that can be done. I could always just active an old Verizon phone, but I need to dig one up somewhere.
Thanks

So I used Odin to restore my phone back to stock. Locked bootloader and lost root. However, the Verizon My Device page still shows my device as unknown. I contacted Verizon and they changed my device ID number in their system to match the Galaxy S4. Still didn't update the My Verizon. Does anyone have any ideas how to get my device to be recognized by the Verizon Wireless Network as a Galaxy S4?

once you have root again you have to edit your build prop to say sch-i545 if it says anything different. when you switch to the prepaid tell them its a SCH-I545 Galaxy S4. My verizon takes months to update the model number at times and its not to be worried about. i think my old phone showed up unknown for a year and a half even before i had root
Just looked, the build.prop file says SCH-I515. Not sure what's holding up the Verizon system from recognizing the phone.
My concern is I can't activate or sell the phone if the system doesn't pick it up.

Hey guys,
I ran the Suckit Verizon boot unlocker exploit, and it was successful. At which point I used TW Recovery to flash Android Revolution HD 8.0 (N7100 ROM). My phone wouldn't connect to the Verizon network, saying I did not insert the proper SIM card. I found this strange, but realized Verizon locks their network to international phones. I then used the Verizon Toolkit to flash back to stock recovery and ROM. After doing so, I still had no luck in activating my phone.
I called tech support (now having stock everything) and they told me it was likely my SIM card. After spending 2 hours at the store today, it is clearly not the SIM card. They have no idea what the problem is...
When I flashed Android Revolution, I wiped my efs. Could that be the problem? Is it possible to flash a new EFS or COM3? I have no clue how to reactivate to the network..
Anyone have this problem? I did a search on both Suckit Verizon and the Verizon toolkit thread and no one appeared to suffer from this. Please help! Any solutions are greatly appreciated. Thanks in advance. Will update if those guys at Verizon come through.
Definitely has to do with wiping my EFS and not saving it. Under Settings > About > Status IMEI is unknown as well as all other carrier info.
Can someone send me their EFS or is their a way to restore the EFS without having backed it up?
Flash the full Odin restore image and that should fix the problem. Note, it will wipe your data and re-lock the bootloader, but it should at least connect to the network again.
If the stock Odin doesn't work since your imei is unknown this may be what you need, but listen to imnuts first

Flashed stock rom. No luck. Now I have to root back, as one of the prerequisites is being rooted. Will get back.
I kind of had this same problem right after I rooted/unlocked and before flashing any ROMs. I was getting signal bars but kept getting a cannot connect to network error every time I tried to place a call. I called customer service and they "reset" my account, whatever that means but it still didn't work. Started driving to the Verizon store and decided to try one last factory reset and it started working! An IT guy at my work said the account reset plus factory reset got my device sync'd with Verizon signal again. Don't know if what he said is true...don't know why it worked...don't know if this will help you but I thought I would share my experience. I know what you are going through so good luck!

I had almost the same problem using MIUI for AT&T's variant. I was able to get most functionality back by accessing the hidden menu and doing the ##RTN#, but still cannot get 4G LTE back. Maybe this will help you get started too.
http://forum.xda-developers.com/showthread.php?p=36163537
According to the OP instructions - which I have done entirely correct. Put phone in Debugging, Went to Qualcomm settings in Hidden menu and set to "RMNET + DM + MODEM" , connected to the proper COM port, clicked the READ on top, however when I go to click the second read to populate the information -> Says cannot set device into DM mode.
The instructions and accompanied video do not reference having to place the device into DM mode at all. The fact that I am getting this error message is also a unique problem.
Anyone know what this could mean or how to fix it? Could it be due to the USB Qualcomm settings not "taking or shifting", although it does confirm that I changed by saying "Saved"
Also, can Verizon Wireless sync my IMEI in store if I bring the original box with the IMEI barcode on it ? Can they flash / scan it to the phone?
anybody?

I know with a fact that the stores do not carry any flashing software for any smartphones. So there is nothing they can do.

I took a USC SCH-R970 down to the USC store and they unlocked it, I had a sim from vzw already so I put it in and the phone didn't reject it so I rooted with odin and then downloaded a stock vzw rom I545vrufnk1.zip and it worked. The phone thinks its a i545, has my phone number, tries to run through the setup but there's no service actually working. My current phone is still working so I guess it's not really activting all the way.
It says it's roaming, I have access to the secret menus (thanks to shortcut master....mad props) and was wondering if there's a menu to check/edit anything to gain service.

Well, i just bought the new Samsung Galaxy S6 Edge Plus From verizon because it's "unlocked" for any carrier. But when trying to see if there's any update it shows "Software update is temporarily unavailable. Try Again Later", does it matters if im not using verizon Sim card? thanks.

I believe you do need a Verizon sim card to access the Verizon software update platform. I know that when I de-activate a phone I get that message until I activate it again.
Try Using Samsung's Smart Switch software for updating.
Yu da man!
I had similar prob when I wanted to unroot my S4 "reformat" and after successful I couldn't update via OTA.... so I did it the hard way with Odin and then was happy, stuck my phone in a drawer for almost a year and decided to put it to service...... same problem again!...
After reading this thread, I realized since a new update was not available I'm getting the error whereas I didn't get it before....
I simply took my existing sim card in my activated Note 4 and put it in the S4 and wallah!... it worked! OTA!
My Verizon account didn't change anything because I didn't actually activate, just only switched sims "so no activation charges".... after OTA done, simply switched it back to my Note4 and now I have a fully updated S4 I can give away!..
Thx!
I got the same problem . I have a galaxy s5 virizon wirless.

Hi, i have been trying to find an answer to this after hours of searching i've come up short and confused.
I recently switched from tmobile to verizon, and i paid off my tmobile s9+ and had it sim unlocked. When i put my verizon sim in it, nothing really happens. either it tells me that it can't register on the network or to insert a tmobile sim card.
I have tried using reset and factory reset. I have also tried the method of holding the volume bixby and power and doing a factory reset, then putting the sim in, rebooting, etc. That doesn't work either.
I see several people trying to go from verizon to tmobile, but i haven't been able to find anyone going from tmobile to verizon, and what method i need to do to get this to work, if its possible at all. Any help would be so much appreciated!

That still may not help, remember Verizon is still CDMA and the T Mobile branded phone does not have CDMA bands activated and they may not even be on the phone, I don't know. Granted band 13 should work fine, being LTE, but could the sim be looking for a CDMA radio and that is why it is not working?

The hardware is identical for all US Galaxy S9 phones. Any bands that may be missing will be resolved by flashing firmware. OP could also just stay with U1 if they want unlocked, and all bands would still be there.

As per Samsung chat support, I've asked if the dual sim version (international) will work with Verizon. I've also asked the rep if I can switch carriers with a locked phone. They said that essentially, all phones were manufactured with the CDMA and GSM band compatibility, it just needs to be unlocked and the US versions will work on any carrier in the US and the international version (dual sim) needs to be unlocked and it will work with any carrier in any country.
That said, it seems that you're just having an unlocking issue - which is good and bad. I hope you figure this out. Try using Odin 3.13, get the CORRECT firmware for U1 or U(VZW) to flash your phone

Only one small correction to what they told you: The 965F (international), will not have CDMA capabilities. That might not be a problem on some US carriers. But if you can't get VoLTE working on VZW with 965F, then you're dead in the water, since you don't have 1x CDMA calling to fall back on. It becomes a data-only device. I don't have experience with it, but I wouldn't be surprised if the VoLTE doesn't work on US carriers. For GDM/WCDMA carriers, you'd probably be just fine with 965F. Even if VoLTE doesn't work, you'd still be able to call.
Hope this helps.

Step 1
Can you find out the exact model number?
For T-Mobile, it will be one of these :
SM-G965UZKATMB (Midnight Black)
SM-G965UZBATMB (Coral Blue)
SM-G965UZPATMB (Lilac Purple)
The U is the important part, as a previous poster explained that the F models do not have CDMA support (forget what that actually means, just know its necessary for verizon)
Step 2
Next, make sure that the carrier version is correct.
Example: SM-G965UZKATMB
BST Boost
VZW Verizon
ATT ATT
USC US Cellular
ACG C Spire
TMK MetroPCS
VMU Virgin Mobile
TFN Tracfone
XAS Sprint
TMB T-Mobile
XAA Unlocked US
SPR Sprint
CCT Xfinity Mobile
Essentially, you need the firmware that starts with SM-G965U and ends with VZW
Step 3
I'm not 100% sure on how to flash from carrier to carrier but there will be a list of directions. You may need to do some research there to see if it will void samsung warranty (aka 'trip knox') or anything like that, if that matters to you. I think only a modified version of Odin will be able to do this.
Download Odin v3.13.1
Extract the firmware file you just downloaded. You should get 5 files:
AP (System & Recovery)
BL (Bootloader)
CP (Modem / Radio)
CSC_OXM (OXM CSC file, will wipe your phone)
HOME_CSC_OXM (OXM CSC file, will NOT wipe your phone)
Add each file to it's respective field in Odin v3.13.1. Use CSC_OXM if you want to do a clean flash and HOME_CSC OXM if you want to keep your apps and data.
Reboot your phone in Download / Odin mode with the following button combo: POWER + VOLUME DOWN + BIXBY
Once in download mode, connect your phone to the PC, preferably using the original USB cable you got with your phone. Odin should detect your device and a blue box will show up with the COM port number.
Do NOT tick any extra boxes. The only options to be ticked are F.Reset Time and Auto-Reboot.
Click the start button, wait for Odin to say 'PASS'. Once the flash is complete, your phone will reboot.

Hey thanks a bunch, I’ll give this a shot when I get home tonight. It very well may be that the rom I got wasn’t the right one. Other threads I’ve read seemed to indicate that everything was universal now and by having the SIM card in the phone while flashing, it would download the carrier specific stuff automatically. That part at least doesn’t appear to be the case since the phone wouldn’t accept it. But I’ll download some of the carrier specifics and see what happens. Thanks again!
Did you get it to work after all?
Sorry that i forgot to update! I did get it working, but it required a bit more discussion and help on a reddit discussion someone started. I noticed that someone asked this exact question and i pointed him to this thread where he was able to get it working, then helped me with which roms he used, and i got it working as well! I've been using it daily for almost a month now. Thanks so much for everyones help, i hope that if anyone else is trying to do this, between the two threads it can help.

Awesome gigatigga - thanks for getting back. I'm on the verge of trying this. I owe some money on my S9 plus on t-mobile but before i paid it off wanted to make sure all is good.
How are the speeds? Everything working ok? Thanks again! :good::good:
Edit: I was all set to do this and during the signup - I found out that my imei wouldn't work in Verizon's system so they used one from another phone. He advised that if I wanted to pay for insurance, if I make a claim it could be an issue because the imei numbers won't match up. Seemed like a big red flag to me. So I didn't go through with it. Wonder how others are handling this?
I just switched from the ATT firmware to ARF4 on T-Mobile, but it says there is no update available, while the newest T-Mobile update is ARF7. Does anyone know how to get updates OTA?

I cannot network unlock a T-mobile Samsung Galaxy 9 plus which has never been active on any plan. When I insert my Verizon SIM card a system notification says "Invalid SIM card. Network Locked SIM card inserted".
I want to bring this phone to Verizon where I have an active plan. I don't have a plan with Tmobile and my friend gifted me this phone. I flashed it to Samsung stock firmware and bought an unlock code from DoctorSim. The code applied successfully however the phone doesn't unlock completely and continues to prompt for the unlock code when I insert the Verizon Sim card. When I called Tmobile they said only a phone active for 40 days on their network can be unlocked using the phone app and that my friend would have to call them to unlock the phone.

I purchase a like-new condition Samsung Galaxy S9+ phone from Amazon Warehouse for international travel coming up in couple days. I figured I would have a better chance of getting an authentic phone from Amazon than from ebay sellers. I received the phone yesterday, and here is the situation with the phone:
- The box of the phone says "unlocked by Samsung"
- The sticker on the back of the phone has the model # SM-G965UZBAXAA and IMEI number of a factory unlocked phone
- The actual IMEI of the phone however shows model # SM-G965UZBAATT, which corresponds to the AT&T carrier locked phone
- When I turn on the phone, it shows T-mobile screen and has T-mobile apps on it
How do I determine whether this is a AT&T phone, or a T-mobile phone or something else? Unfortunately, I do not have either TMO or ATT sim cards that I can use to check which network the phone works on. How do I know whether this phone is unlocked and if it is will work internationally? I am not sure how to explain the imei of the phone coming up with ATT model number, yet the phone shows TMO screen.
Please help as I need to get this resolved today, and don't have time to purchase another phone. Thanks much in advance!!

put any sim in it and it should work these phones are multi carrier means all the us models are the same if its att imei id say its unlocked since obviously last used was t mobile but if you put any sim in it other than att it should accept it and not say unnsuported sim and or ask for unlock code
to further this as i said the us models are all the same. They have a file called CSC which determines carrier based settings you can put in a tmobile sim and it will repersonalize for tmobile then swap to att and att will show up..
Its the way of the future and actually quite nice as one firmware pretty much covers all carriers other than specific user data which is that carriers apps
it may be unlocked obviously the listing was wrong but xaa is factory unlocked for sims, You can reflash xaa if it is unlocked for non carrier branding,But id put any sim in and see

I downloaded the phoneinfo app, and here it what it shows:
Firmware's CSC code: XAA
Active CSC code: TMB
IMEI check shows model ending in: ATT
That made me highly confused as to whether this was a AT&T phone, a T-mobile phone or whether it was originally sold as factory unlocked.

Under Service Provider SW ver., it shows TMB/XAA/ATT
I am trying to understand what this means, why would it show TMB, XAA and ATT? Does it mean the phone was originally AT&T, then someone installed XAA firmware on it and used it on T-mobile. If that is true, is there a way for me to verify whether the current installed firmware is XAA?

That is correct. You see it now. The third csc code is the original device. The second is what csc you have running. And the first is or was sim inserted.
Look in settings about phone and software info. At the bottom somewhere it should show you

Yes, what I pasted above is from about phone->software info. It shows the service provider sw version as TMB/XAA/ATT. Thank you!!
