[Q] Samsung Vibrant – Not network after unlocked

T-Mobile Vibrant SGH-T959
firmware 2.2
Baseband: T959UVKB5
Kernel version: 2.6.32.9
Build Number: FROYO.UVKB5
I am having a mayor issues with my phone after it was Unlocked, First i was given the unlocked code by a third party vendor (I give them my IMEI#) and it was not taken, so the phone had to be hooked up to a tiny box (x3 something)and i guess flashed in order to Unlocked it after the 3 flashing the tech was able to successfully unlocked the phone then we put a ATT sim card test it and I was able to make a call fine. So when i got home i put back my T-mobile sim card and were the 3G/5 bars usually are there is just a circle with a slash on the middle, so i switch the card to a ATT sim and it does the same, Now the phone is not recognizing any network at all.
When i go to the phone Settings-> about phone-> status-> everything shows OK except under
Network = Unknown
Service State = Out of service
Roaming = Not roaming
Mobile network state = disconnected
...this is the same whether i use my working/active ATT or Tmobile sim card
Any suggestion of how to fix this phone will be greatly appreciated

The tech (or the lack of it LOL) has forgot to flash the modem back to the one matching the firmware in the phone, that's why you're having network issues. You can do it yourself by using Odin and the latest firmware from samfirmware.com
Good luck,

[Q] Phone not allowed mm#6 error message

Phone: SHG-I317
Carrier: AT&T
Current Firmware: 4.1.1
Hey guys, I purchased this phone and have yet to officially activate it. I downgraded from 4.1.2 so that I could unlock it to work on other networks. I did the unlock procedure and I attempted to put in a METRO PCS Sim card but I get: Phone not allowed mm#6. The phone is not blacklisted as Ive checked numerous sites online and even went to a AT&T store and they were able to pop a AT&T Sim card in and it worked just fine.
I tried to search this issue but the only thing I can come up with was that it could possibly be blacklisted but Ive ruled out that possibility for now.
Could it be that the unlock was unsuccessful and I need to do it again? But then how am I supposed to know that it was successful without another carriers sim card? is there something that changes in the settings or something?
Thank you very much for your help.

I need help on samsung note 4 N910v

My friend brought an original refurbish Samsung N910v android version 5.01 which was working with GSM 2G if not 3G until when I tried to update to new version android v6.0.1. In the menu>setting>about when I checked first before anything it showed me N910 F v5.01 but in boot mode Odin it was N910v.The problem started when I just typed *#9090# the phone immediately started reboot loop. I have managed to unlock the boot loader and root the phone installed custom rom version 6.0.1 by Paul Pizz rom VRU2CPJ2.r-1 but still can not have 2G or 3G GSM network. Please help to revive the phone again whether it meant to go back to 5.0.1 that would work with gsm cause am full stack now.

Have you checked to ensure you have the APN information in place? I have a Galaxy Note 4 N910V now (just got it a few days ago) and when I put my T-Mobile SIM in it from the very first time I have to manually put in the APN data - on custom ROMs it's usually picked up and there automagically but not always so, my suggestion is that you check to make sure your APN information is currently there as it should be.
Settings - More - Cellular networks - Access Point Names - make sure the one you need to be using is selected and if it's not then you'll have to put that info in manually and save it.
As for the actual model number, take the battery out and see what the model number is on the sticker in the battery compartment area - if the sticker isn't there then it could be a device that someone has done some experimenting with because that info can be changed. The sticker should be there, of course, but sometimes people take 'em out when they're mucking around with stuff, who knows.

The APN will be your network. Are trying to use Verizon? If so, you should have a spot to tic the VZWINTERNET. If not, then you have a sim card issue.

Is the sim from verizon? If you have a good account go to a corporate store and have them give you a new one. It's free.
Also, what are your APN settings and I will compare to mine. Everything works on mine.

- N910VVRU2CPJ2_FullFirmware_NoAboot<--- Full Framework with no aboot so you will not re-lock bootloader, but will unroot and restore back to 100% stock. once your on the full stock check if your connections are working fine, if they are then install custom rom, otherwise change the sim card

go in settings, connections and select network mode to global, should be fine

Unregistered Sim N930W8

Hi All,
Trying to put this phone on the network but received the error unregistered sim.
Rogers network.
Is there a kernel or Rom flash that would resolve this?
Trying to put it on the network so I can get into Samsung tools and reset the lock screen.
Thanks
