[Q] Demo note 2 imei and baseband problem

Hi i have been given a samsung galaxy note 2 but it is a demo from samsung. It has everything in it but it doesnt have an imei and doesnt register to a network. It has a sim slot but it doesnt pick up network. If i type *#06# it says imei null. Also another thing i noticed is that it has no baseband version. It keeps loading retail mode from samsung all the time however i have managed to get rid of it. Is there a way to flash it with different firmware to get sorted. I am not an expert so if someone can guide me step by step that will be great.

Return the phone and request a new one mate. Your story sounds fishy to me to be honest

There's nothing fishy about his story. Samsung demo units only contain WiFi connectivity options to discourage theft and resale.

Its not fishy it has been given to me by samsung for demo in mobile stores in uk. It does connect to wifi as someone mentioned its just it dont pick sim cards probably because samsung blocked it. As i got a sim with unlimited data i want to use it and get rid of my dongle and laptop.

Since samsung supplied it (in your words) for demo in mobile stores in uk I doubt they would be particularly pleased with it being supplied with an imei (which is TOTALLY dodgy to me) for personal use when it was never intended for that!
Sorry dude but it does sound fishy.

No manufacturer would be pleased to install custom roms too..... So solution please if you have any?

I would not flash anything if you have these issues right from the get go, take it back to place of purchase and or call your carrier. Demo is just that Demo...
Thank You and Thread Closed, before this goes into the woods....

[Q] Newbie here - unlocked i317 "MM#6 Phone not allowed" for overseas network

[Q] Newbie here - unlocked i317 "MM#6 Phone not allowed" for overseas network
hi all,
I'm new to this forum and its great to be associated with such a wonderful group
I bought an unlocked AT&T note2(i317, android 4.1.1 and firmware- i317UCALJ2) off ebay.com and got it to India a month back from WA.
I have been trying to configure mobile network on Indian carriers but always got these errors :
- " your sim card doesnt allow connection to this network" and "MM#6 phone not allowed"(MM#6 appears only since yesterday)
- the network bar(i.e. signal strength icon on home screen) doesnt capture the local networks at all which is quite surprising.
- Phone's IMEI(35700..) doesnt match IMEI on the back panel(35542..)
I heard about cases where phones purchased from ebay/craigslist getting blocked ( for example, http://forum.xda-developers.com/showthread.php?t=2341622) but I guess that shouldn't stop it from using overseas? Also, I heard IMEIs of such blocked phones look like "null", "0"s etc. but IMEI of my phone looks good and doesn't showup in the list of blacklisted IMEIs on swappa or CheckEsnfree. Lastly, I also checked the GSM bands of i317 and they are definitely compatible in India.
Can someone kindly help?
Many thanks in advance.
Chaitanya.

I would like to add that I have tested SIMs from multiple carriers but failed to locate networks and APNs. All other features like WIFI, Bluetooth etc are working like a charm so I suspected if it got to do something with the IMEI.
I request some guidance from the experts in pointing to the issue so that I can try the workaround(Sorry..Im a novice at troubleshooting android )
Kindly let me know or redirect me to a forum if already exists.
Thanks,
Chaitanya.

Could you please say your baseband? It's in settings> about> phone.

Thanks for your reply mate.
Here are the details:
baseband - I317UCALJ2
CSC - i317ATTALJ2
Bootloader - i317UCAMH3

The good news is your phone is clean stock.
The bad news is your phone is blacklisted, and the IEMI was hacked/changed.
The only legal way to solve this is to contact the original carrier (I'm guessing AT&T USA), give them your IEMI, tell them you bought it legally in the USA, and ask them to unblock it. The blacklist is all US carriers and their overseas versions, all European carriers and their subsidiaries. Like Orange or Voda or t-mobile.

My bad..I should have checked the status beforehand in detail. Till now I was only aware that bad IMEI phones arent allowed majorly in US only (saw many such phones being sold on ebay intended for international use ).
As far as I know, i317 is only the at&t version of note2 in US and it differs a lot from its International versions (gt 7100, 7105 etc). Do you still think this blacklisted issue holds good in countries where i317 isnt available?
Since sending the product back to US is highly unlikely, can you kindly let me know the best way I can get the issue fixed?

Answered in my post above. From India you can probably use the tech chat from AT&T website.
It's a blacklist of disallowed IEMI's so the model is irrelevant.

Thanks Rangercaptain for your clarification. I tried AT&T's live chat but it seeks registered contact details to login. Is there any email support?
Not sure if these kind of questions are allowed here but I heard there are tools that help to retrieve lost IMEIs (which work on rooted phones).
In case it gets tough to get hold of AT&T, can I try any of such tools on my phone since it is not registered in my county anyway and doesnt come with any warranty?
P.S:I know changing IMEI is illegal but I guess retrieving it is not :fingers-crossed:

I started to think may be the motherboard got changed(since S/N also looks different and the phone looks absolutely new with no wear at all)?
I'm being forced to think that IMEI is clean because some followup with AT&T and US Samsung care have confirmed that the phone's back IMEI and S/N are definitely good with warranty till 2015 and don't show up in any of the blacklisted lists.
I'm sorry for posting different questions but please note that I'm not much aware about this phone's history and I'm trying to openly share the results from my extensive findings. Thanks!!

If you're sure everything is clean are you sure your Sim card is correctly provisioned for the network? The easiest way to find out is to trade cards with a working phone.
Before you think about trading main boards (I did that because the gps connector was broken) go to www.mobiletechvideos.com and see what they can do for you.

Yes, I have been trying this on a working sim with an active data plan which is currently working on my xperia.
Over the last 2-3 days, I have learnt that flashing a wrong ROM sometimes might corrupt EFS folder that stores IMEI,serial number etc., and reinstalling firmware through ODIN(which requires to download original stock ROM separately) or KIES software might restore the lost EFS folder.
I thought of giving this a try and accordingly reinstalled the official firmware but without any success.
Can someone redirect me to any such guides/threads that might help? If it doesnt happen then I would like to close this thread and create a new one for EFS related troubleshooting.

If efs is corrupted there is no s/n or imei shown. It displays null

Importing S7 active to Europe

Dear xda
First off, I absolutely love the concept of this phone: strong, big battery, great hardware,... and I dont really mind touchzwiz (the way it is now).
I'm wondering if it interesting to import the s7 active to Europe or not. As far as my research goes, this is what i found out:
at&t has an unlock service via their website
íll have to pay import duty and VAT (is this also the case if I purchase a "used" phone?)
at&t's s7 active supports all bands, so no problem there
at&t has some bloatware which shouldn't be to much of a problem to remove
updates will suck big time, unless we get root and we update the rom ourselves.
If anyone has info about Samsung introducing the s7 active to Europe, please let me know.

Wondering this myself

Yes it will work. Relatives just went to Europe with 3 S7 Actives we got att to unlock as they were bought outright. Work fine on Wind and Cosmote carriers, and will be sold to friends before they return.
Package Disabler Pro works to disable samsung and att updates and bloatware without root.
Those 3 Actives will pay for mine; sometimes carrier exclusivity is a great thing.

Wondering about the import duty and VAT if I import a used phone.
Anybody know?

There's plenty of post on what to disable manually so no need to pay for an app as it does the same thing. If it's convenience you want then the app will help but there's plenty of post for all provider variants of Samsung phones on xda and reddit.

Import duty and taxes will always have to be paid. If you buy second hand make sure a proof of purchase is included otherwise they will charge the tax of a new phone. You can get a friend to take one home with him/her and they will not pay.

I've bought the S7 Active this week in Switzerland. The phone was unlocked already. Inserted the SIM card from my local provider Swisscom and it works perfect.
Only what I do miss: no BT SAP support.

Hiow did you manage that? Where/who did you buy it from?

No option to do software update with s7 active.
Hi anyone know how to get ota updates on the s7 active in the UK?

You don't. Updates need to be flashed from the sd card or with a computer via odin.

Hello
I've about the same questions for an use in France : how difficult is it, once received (supposively an ATT one unlocked), to update up to last android version oreo and is there a loss of functionnalities if not used in USA..?
Thanks in advance
Julien

I use it regulate in Italy (un-lock of course) Oreo 8.0 G891AUCS4CRG3, I'm looking for a way to improve reception, perhaps replacing the modem software with another modem software

Hello
Thanks @Matad1974 for your reply, so it's possible to use it in Europe without too much difficulties and loss of functions..? Which method did you used (OTA/KiES/Odin) ?
About reception isn't it because there are bands missing..? I've read somewhere using code #*#*4636*#*# you can choose bands, have you try ?
Thanks in advance
Julien

Hello, I bought it directly from the United States already unlocked, it works well, but the reception is a bit poor sometimes, where before with the same card took good, and when I talk to someone my voice sometimes is not very understandable .. because of this maybe changing the modem maybe it gets better.
With this code #*#*4636*#*# it does not do anything to me
I took a ride on the internet and I found this code, I try various settings code *#2263#

I can recommend it for european users as well. You lose some of the newest features I think, like Wifi calling.
Updating is pretty simple but a little inconvenient since the update does wipe all your data. There is a thread in this forum that can help you.
Also you should only buy from a thrustworthy seller, but that's just common sense.
(Changing bands can also be done with an app, for example "Network Switch")

SM-N976U on Verizon Network

I picked up and unlocked an SM-N976U on AT&T and dropped in my Verizon SIM. All is well, expect for a few things. I was wondering about flashing the device with a "standard" firmware to remove the AT&T garbage but I cannot seem to find the details on how to do this. Any guidance? Thanks!

Hey the way to get unbranded is go to dialer and type *#272*IMEI NUMBER#
You'll get a screen that let's you choose the csc code. XAA is the generic unbranded. But from what I understand once you do it, it's hard to go back.
Try at your own risk. I think a guy said it messed up his bands or something like that.

@tyrone1... your instruction worked like a charm for me... I had SM-976U AT&T unlocked... I wrote down my IMEI and used *#272*My IMEI# and got a screen where I can make
Sales code and Network Change or Only Network Change.. I chose Sales code & Network Change and next screen I choose TMB.. after that I popped my TMB sim and it restarted my phone.
The phone booted with Tmobile splash.. and just verified that the Video call works (yaay)!!!
Thank you !!!!!!!

Trying to get samsung pay on a device (s20+) without it - maybe changing CSC?

Hello.
Here's the back story. Bought my phone from Egypt unlocked s20 plus. Recently moved to canada and trying to get samsung pay to work. Downloaded the app from google play canada but it says that device is not supported. Downloaded it from APK mirror but it just says it needs to update, even though this is the last version.
I was told that getting the BTU or DBT CSC might fix this, since they come preinstalled with samsung pay.
First of all, can I do this by just flashing the firmware (not changing CSC)? Or do I need to change the CSC using samkey? I don't mind flashing first, if that didn't work then using samkey. But would rather go with the route that people think will work straight away.
I'll write all my device's info that I think might be needed to make this as complete as possible. Then I'll put some questions that are confusing me.
So to start this, I bought my phone from Egypt and I'm currently in Canada. Since it's a dual sim model, I have a Canadian SIM as my primary and Egyptian as my secondary. Currently, I'm getting wifi calling but not VoLTE. Reading a bit on this, some people are saying that my network intentionally locked people out of this option if they didn't buy the phone from them. My network is Fido btw.
Model: SM-G985F/DS (4G)
Product Code: SM-G985FZADEGY
PDA: G985FXXU4BTIB
CSC: G985FOXM4BTID
Basebad: G985FXXU4BTI6
Bootloader: G985FXXU4BTIB
September Security Patch.
One thing I'd like to point out is typing "*#243203855#" in the dialer does nothing. Maybe it's because it's not supported? Or the fact that I have dual IMEI?
Questions:
1. Is there benefit of using DBT over BTU?
2. With my bootloader being BIT 4 (I think?), can I use samkey? When I checked it, it said that they only support BIT 1 and 2 on their website. I could be wrong.
3. Is it safe to purchase samkey credits off ebay?
4. Is samkey itself safe? It showed up as a trojen when I installed it. Could be a false positive? Downloaded from the official site btw.
5. Is flashing BTU enough for this to work or do I need to change the CSC?
6. Can I revert any changes that I've done to restore the device in its original state? If I change the CSC, can I revert it back to EGY?
7. Will I get normal OTA updates while I'm here in canada? This applies to both flashing and/or changing my CSC?
8. I would love to keep wifi calling, call HD, and hopefully get VoLTE (but I understand that this might work). And obviously the main reason for this whole thing is getting Samsung Pay to work.
Sorry if these questions might be obvious, I'm really trying to understand this so I don't ruin anything and don't regret anything.
If someone is willing to help me further, I would greatly appreciate it.

I am unsure about majority of the things you have question about, but one thing i know for sure - samsung pay on my s20+ was rarely working making me look stupid at the shops - since i switched to google pay all issues are gone and payment is going through everywhere

The one thing that I care about with samsung pay is the magnetic card replication. I forgot what it was called MTP, or something? This is something that doesn't work with google pay.

The MST function was disabled in 2019 for all the smartphones sold within the EU (at least) due to a new regulation regarding MST technology.
I don't know if it's working elsewhere.
Still, for me SPAY has been working flawlessly for over an year or two, never had any problem, with or without MST

Oh? This might actually be useless than. So this is a hardware change or a software one? Since mine was bought from Egypt. I plan to flash the UK software on there. I'm not sure if it'll have it or not in this case. I guess without MST, what's the point of using samsung pay over google pay?
