Lost Data After Nougat Update. T-Mobile on Sprint Device - Sprint Samsung Galaxy S7 Questions & Answers

Hi All,
I have recently updated my Sprint device, which had the mobile data working flawlessly before updating. Now I want to fix it and I want to flash my device to a T-Mobile firmware but I kinda lost between forums. Where should I start? Can someone outline the steps for me?
Thanks!

Start by flashing the latest T firmware to it , if that doesn't correct your data and its showing invalid sim then your device may have been re-locked which I'm seeing a lot of lately

Lost Signal after Lollipop update

Hi guys
My phone was rooted but never flashed a ROM on it. Today I updated my phone to Lollipop through Kies Mac. After that my signal is not there. When I reboot the phone I get signal for few seconds then it gets lost again. Also phone never saves my Wi-fi connections.
I did reset my phone but still the same.
It was locked to Vodafone and I unlocked it in Vodafone shop when I first bought it do you think anything related to that?
How can I downgrade to KitKat or get my signal working?
Same here. Do any of you guys know how to solve this issue?

Please use the search function of this site and google, don't be lazy. There is a thread about downgrading . Also try flashing lollipop modem/bootloader, for this visit any of the TouchWiz Lollipop rom threads (like the one in my signature) most of them talk about flashing modems and bls.

[Q] GS5 KDI AU lollipop upgrade lock.

Thank you everybody in advance for the help you may provide.
Please could you help me to understand if i can fix my scl23?
This is the thing.
I got myself a KDI au gs5 scl23 with kitkat 4.4 and as i understand its rooted with a custon recovery, beacaus of the sim unlock, and the recovery its in japanese.
The phone works fine, but when i try to use it on ultra saving mode, its says that it`s samsung account isnt activated and doesnt allow me to change it(in the settings of the phone there isnt a way to change samsung account). So it bugs on that samsung account, and doesnt allow me to use internet and the keyboard when im on the ultra saving mode. By the way i live in Argentina and cant find anyone who speaks Japanese.
So, Trying to fix this samsung account problem i upgraded to lollipop 5.0, but it lock the phone and it doesnt get any antena signal, its says insert a sim, but there is no "no sim" mesage on the mesage board.
And now im dowloading the 4.4 firmaware files to downgrade it to 4.4 and to unlock it whith service menu commands.
Have anyone been able to unlock it with service menu on lollipop, or in any other way? Beacuase lollipop fixes the samsung account problem but olso locks the phone and installs custom AU rom, only in japanese or english laguage.
Thank you very much to everyone.
same here
This is the same thing that happened to me, did you manage to revert back and unlock the simlock on 5.0? Any luck upgrading to 5.0 and using your sim with the device.
cheers

Ended up downloading the 4.4 rom for phone again, installing that. Had to clear cache and do factory data clear to get phone booting again after downgrading. Then I was able to complete the Sim Unlock steps outlined here
http://forum.xda-developers.com/galaxy-s5/general/tutorial-unlock-sim-au-kddi-galaxy-s5-t2891992
Super frustrating using a phone like this, as it has so much bloatware from Japan which I just want to get rid of. But up and running now, with several replacement mods for keyboard, messenger etc
A lot of information out there, thank you internet and forums like this one for having so much information to get things working again. :victory:

No phone calls?

Hey guys, I come here very often and now I'm going to have to open this thread because I've seen absolutely no posts about my problem..
My S6 Edge+ is currently unable to make any calls and I don't know why..:crying: the strange part is that I can still send text messages and use my SIM's mobile data... Another weird thing is that whenever I reboot the phone, my WiFi passwords are forgotten..
Can any one help me? I'm currently running android 6.0.1 and I am considering downgrading it to 5.0.1 to see if it solves the issue...
Still needing help..
No one?? I really need some help since I've tried 4 different roms and modems ano nothing seems to work....
Have you wiped everything and then flashed a stock rom?

Which variant do you have and which MM firmware did you flash? Check your modem, imei, network operator etc and provide that info here.
Also wifi password IMO related with
Code:
ro.securestorage.support=true
this line in build.prop. I would suggest you to add this line under 'ADDITIONAL_BUILD_PROPERTIES' in build.prop but assume you havent rooted your device. If have, add it.

I've downgraded to 5.1.1 and it didn't work, I have the international version of the s6 edge plus and now I'm looking for a new ROM to test to see if I can solve it.. I've checked my imei in two different websites and on imei.info it comes clear, but the other site gives me a blacklisted warning, which makes me think since I bought it online second hand... it probably was reported stolen or lost and now it's blocked... which ise rather inconvenient. .
If I go to SIM Card Status it says "Not Available" everywhere, but on imei information it says my imei and on IMEISV the value is 01. It's network unlocked and right now I'm about to flash a new ROM, probably stock..
Hello, I have the same problem at boot after I receive the call when making a call nothing remains of numbering you have a solution? thank you cordially guillaume
Hi guys, I know this is a really old thread but I'm here just to say that the problem was with the IMEI, it was blacklisted..
I changed it with a friend and then everything worked fine..
Thanks for you help mates!

S8-G950U Problem

Hello guys i have one big thing to solve here i hope you are going to help me.So here is my problem:
I have an S8(G950U) which i flashed with T-mobile firmware from Sammobile.The phone worked totally fine for 7 days.I even updated the software the day i flashed the phone.Today i just woke up and i got a message on my phone saying that for security reasons your phone is locked.Now i cant even use T-mobile(Macedonia card),and not even my main operator(VIP MKD).Can someone help me what i can do? The phone is snapdragon,and the IMEI IS: 355987080853152. Its not blacklisted i did check it out.
I have 2 questions only:
1.Do phones get locked when you flash it with carrier firmware?

Thanks to everyone that is going to help.Kind regards

Flashing stock with Odin is harmless, I'd go for it

Thanks for replying
Yes indeed odin is harmless but my only concern was sim network lock because i have usa AT&T note 4 and i live outside usa .
previously i had sprint note 4 and i flashed stock via odin and it got network locked it was showing "invalid sim" but this doesn't happens with Tmobile/verizon/AT&T thankfully .
thats y i thought better to ask and take advice in xda.
Have a good day:good:

Now that you mention it, I did get that error on my T-Mobile Note 3 a while ago. I upgraded to the latest version via Odin (I also live outside the US) and the phone is unlocked, but I kept getting invalid T-Mobile SIM inserted and didn't get any data.
Fortunately, my plan wasn't to go back to stock, only to test GPS (Google Maps) on stock. After that, I went immediately to a custom ROM and did not get that error any more.
Hope you don't get it xD
Good day :good:
