PLEASE HELP!! Carrier Switch or Just Flash Carrier Rom? - Samsung Galaxy Note 8 Guides, News, & Discussion

I have a T-Mobile version of Note 8 purchased from Samsung. T-Mobile unlocked it for me since it was purchased in full and I used it on Verizon with no issues (even received ota updates). My current setup shows SPR/SPR/TMB. I am currently on bootloader v4 and I am not rooted.
AP:N950USQU4CRF3
CP: N950USQU4CRF3
CSC: N950UOYN4CRF3
I am trying to have the latest Note 8 sprint firmware (N950USQS4CRE1).
Current Problems I hope to solve: VoLte does not work, keep getting random MMS error 225, internet super slow although I just got the service and on unlimited plan. Internet is slow in multiple zip codes despite them saying 4g LTE is covered in those zip codes.
What files would I need/Where would I go to get them?
Do I need to "carrier switch?" If so, I don't see any v4 files and after searching the thread I am still at a loss. Any help is appreciated.

[Q] How to Force Sim Unlock Prompt

Hi there,
I rooted my phone. I've installed Cyanogenmod 7 and enjoyed it. However, it is SIM locked. I purchased an unlock code... but now I can't enter it.
This person had the same problem:
http://forum.xda-developers.com/showthread.php?t=1313393
Cyanogenmod does not prompt to unlock even with a foreign SIM card.
The solution was to revert to a stock firmware. Which is great... except for the fact that my phone's model number is:
i5500m.
It's the dreaded Canadian version. I can't find firmware for it anywhere. I've tried Check FUS:
Product Code: GT-I5500YKMVMC
No firmware info retrieved for given data.
Generally it seems like I only have two solutions... and one failure.
The first solution is to find a stock firmware for this phone. Or receive a backup from someone who has the stock firmware with Clockworkmod.
The second solution is to enter the unlock code without the prompt. Is there a way, an app, or a hack to do something like this?
My failure is to accept that there's no reverting. But I don't really want to do that.
Oh, and thank you for welcoming me into your forums. XDA Developers is a really amazing site. I've thanked it plenty of times for saving my ass.
Thanks for your time,

Look closely at the latest changelog and notice that point 12 states -
"Network: SIM lock messages will no longer be ignored. This may help people who have problems using SIM cards that require a PIN unlock."
Good luck

Thank you so much! I missed that update by only two days. I'm sure this will help many people.
I'll edit this post with my results once completed.
Thanks again!
Sacrosaint.
---------------------------------
Results:
So I updated the ROM. I did not do a data-wipe. I inserted a foreign SIM card. It says it's connected but I'm not getting any service... I don't believe it's unlocked, as I haven't entered a code yet.
Perhaps I should do a data-wipe and retry. I'll repost afterward.
---------------------------------
Potential Final Update:
Odd! I inserted a Rogers SIM card into my phone running CyanogenMod and although no unlock code appeared... it worked. Also known as: my phone is unlocked.
Some interesting thoughts concerning this:
My phone model is i5500m. It comes locked to Bell or Virgin Mobile in Canada.
Upon trying the bml5 unlock method, my code came up as "01234567." Others experiencing this problem concluded that the phone was hard locked.
However, it would appear that flashing this ROM effectively removed the SIM lock. That means that originally, the SIM lock was a part of the firmware. That is slightly scary. I wish I would have come to this conclusion earlier, however, as I paid a premium of $40 dollars to unlock it (at least I supported a local business.)
So: for i5500m or Canadian Samsung Galaxy 5 users to unlock their phones, they must simply root and flash a custom ROM. Originally mine was from Bell, and it has worked with a Rogers SIM card. I'll possibly update this tomorrow when I try the phone with a Koodo SIM.
Hope this helps someone out there.

Sacrosaint,
I have an unlocked GT-I5503YKAINU running baseband I5500LUYJP2 and ROM CyanogenMod-7.2.0-RC0-galaxy5-v1.9. I inserted a Virgin Mobile Canada SIM card and do not get Service. With a Rogers SIM card, I do get Service. I spoke to people at Virgin and they said it's because my phone doesn't support HSPA+. The reason it works with Rogers is because it supports GSM.
I'm wonder if there's a way to install the baseband firmware from GT-I5500YKMVMC and still use CyanogenMod-7.2.0-RC0-galaxy5-v1.9?

What the representative said was true.
Virgin is both HSPA+ and CDMA. The Galaxy 5 IS a GSM phone. Its radio will not work with other frequencies.
You will want to go with Bell, Rogers, Telus, Fido, or Koodo, the GSM suppliers, my friend.

[Q] Can't seem to fully reflash SG Note 2 with stock ROM. Help please!

Hi, and firstly, thanks to any and all who offer their knowledge to assist my conundrum.
I recently purchased a Bell Canada version of the SG Note 2 (i317), I am on Telus so I attempted to Unlock the phone. I looked online and found people were having success unlocking these phones for free using the *#197327640# method, (whereby you go into the service mode, turn off the PERSHO_256 and then INITIALLIZ).
I tried this method and the phone then seemed to work with my telus sim, but only for voice, not data. When I put in a Bell SIM from a friend, both voice and data worked fine - which tells me its not a hardware (radio) issue. I also tried using another friends Telus SIM and had the same results as mine - which tells me it's not a SIM error. Also, all the settings in the mobile network area appeared to be correctly set up.
So, my next step was to try and reflash the phone to the stock Bell ROM and then just buy an Unlock code. I downloaded the stock ROM (2 different ones actually) and used Odin 3.07 to reload the ROM. I've tried it several times now, with both Bell ROMs and each time it says it's been successful, but the phone remains in the same, partially unlocked state.
It seems as though by using the PERSHO_256 method I have permanently, PARTIALLY unlocked the phone. I can't seem to re-lock it by installing the stock Bell ROM, and since it's unlocked, I can't get the foreign SIM error to come up to enable me to put in my purchased unlock code.
If anyone has any insights, it would be GREATLY appreciated. Thanks!

You should ask questions about a specific device in its own Q&A. (unless it doesn't have one). Cuz people there have the same phone and will know exactly what to do.
LIFE! IT'S WHAT YOU MAKE OUT OF IT!
Will do, thanks for the tip!

[Q] Phone settings say g900f but odin says g900t

Hi Guys,
2 months ago I bought a Samsung s5 in Hong Kong.
While travelling through South East Asia this device worked fine.
While traveling through New Zealand (Old home) this phone worked fine.
While traveling through America (New Home) this phone worked fine for the first 2 weeks (on the metroPCS network).
The problem:
Randomly after 2 weeks the s5 stopped connecting to the metroPCS mobile network even though the network was available (btw metroPCS uses the T-Mobile network). It gives errors such as network not available or cannot register with network.
Things I have tried:
-Im sure the APN settings of the phone have not changed and I have double checked to see if they are correct.
-replacing the sim card with another does not fix the issue
-soft and hard reset of the phone does not fix the issue
-Getting metroPCS to refresh the service on this number does not fix the issue
Other important info:
-This phone was purchased in hong kong but it is from the Philippians according to Kies's firmware information (XTC is the country code)
-It is running a custom allianceROM that must have been installed by someone in hongkong
-The device is rooted (superuser app installed)
-the model number as shown in settings is g900f BUT when attempting to flash with odin the phone displays g900t and fails to flash the latest Philippians verison of kit-kat
I have 2 questions:
1. Any ideas why my network connection has suddenly self destructed (and how to fix)?
2. Would flashing a stock ROM to my s5 help? and if so why is there conflicting information on which model I own (g900t/g900f)?
Please help. I do have some know how on flashing android devices but i've really hit the wall on this one guys!
Cheers,
Yetti.:cyclops:
It's not uncommon for the model # to be different with a custom rom as that is a very easy thing to edit in the build.prop. It should tell you under the battery which one it is. As far as the network issues, check to see if the baseband and IMEI are still there and not listed as unknown or incorrectly. It's possible you could get away with flashing the appropriate modem that matches with your update and that might work better in this region vs the previous one.
Please list the Alliance rom version and baseband version here in case it's relevant to your issue.
More info
Im not sure if this helps but looking through the build.prop file in the system folder my ro.product.local.region=GB
When in recovery mode the region is set to XTC (Philippians) using mutli-csc.
Also my IMEI number seems ok and is NOT blocked.
Cheers. Yetti :cyclops:
Baseband and rom etc
Thankls for your reply!
Sorry when you say "under the battery symbol" do you mean in /odins boot script on the device/ or /in settings on the phone/?
Baseband is g900TUVU1ANCH
Build Num: AllianceROM_G900F_XXU1ANCF
If the "no network" issue can be solved with the current firmware that would be the most desirable solution but going through the flashing process may be a good idea for my learning process, and will help with future updates.
Do you think getting back to a stock rom would help me?
tHANKS AGAIN!:cyclops:
Model confirmed to be g900t
Sorry i didn't understand the "under the battery" thing. I was lost in software world. The sticker under the physical battery says SM-900T so i guess that confirms that it is a t-moble verison (and the baseband is therefore correct).
I will try to flash the T-Mobile stock image to the phone and see if that works.
Also i will try to flash a modem (after i work out which one i need).
Cheers, Yetti :cyclops:
Current status.
Flashed the stock T-Mobile firmware to the phone. No success.
Flashed new modem to the phone. No success.
Will go to the T-Mobile store tomorrow to see if they can help (I doubt it but i have to exhaust all the options).
Any more help would be appreciated...
cheers, yetti:cyclops:
By under the battery I mean like to take off the battery cover of the phone and pull the battery out and look at the sticker found there.
G900t.

Yep it says g900t (see above)
As per flashing a modem. I have heard that it is possible to flash any modem for any version of the s5 to the phone. Some work well and others not so much. I have tried 2 T-Mobile modems (baseband) the G900TU1ANCH and the G900TUVU1BNG3 with no success. Do you have any recommendations for a modem to try (or even a custom ROM that might help?)
Cheers,
Yetti :cyclops:
I know that you mentioned they refreshed the service for your number, but do they have the correct IMEI in the system for your account? Metro makes a big deal about that now and you can't just take your SIM from another phone and pop it in a new one and go like you can with pretty much every other service (Cricket is like this too now).

I need help with my Samsung S3 SGH-I747 AT&T

Alright, so my parents sent me a Samsung S3 SGH-I747 AT&T Carrier...
Problem is that I live in a different country, that would be the Philippines and I was just wondering, if there would be any way possible to get rid of this 4.1.1 I747UCDLK3 Firmware that it comes with
Reasons being:
1. Locked Mobile Hotspot (saying Mobile data is not available (though I activated it) or Invalid SIM Card)
2. So much unnecessary bloatware
3. Using mobile data has become impossible (Globe Telecom carrier), though I can receive texts and calls
What I've tried so far:
Odin, but it just kept on giving me the "SECURE CHECK FAIL : aboot" error and cancelled the Firmware flashing...
Also, if I have to flash Cyanogenmod or any other firmware just so I can port it to a different stock firmware apart from AT&T, that would be epic.
Thank you in advance...

Getting Tmobile Updates on phone with SW ver Tmb/Tmb/Att and Att baseband version

I bought a s9+ from swappa around February. I bought my mom one from the same supplier a week ago. At first I was concerned that her's had ATT logo until I realized it would change once a tmobile sim was put in. Her's is now SW ver Tmb/Tmb/Tmb. Then I noticed she is at Android 10.0 UI ver 2.0. I am stuck at Android 9 UI ver 1.0
So It seems I was worried about the wrong phone. It is MY phone that can't get updates. My baseband is:
G965USQU7CSK6 which I believe is an ATT baseband. my SW ver is Tmb/Tmb/Att
I tried connecting to smart switch and it says I am up to date. I tried putting in an at&t sim card (that no longer is in service) and smart switch doesn't complain about anything but it still says it is up to date. Doing OTA while using At&t sim card also says I am up to date. I am CLEARLY not up to date. My last update says Nov.1, 2019.
I have used Odin before...mostly for rooting phone. I haven't rooted since the s5 ( where I could take the battery out ). Little paranoid to use Odin considering I can't take the battery out, but with good instructions I will proceed.
Any help on how to update and especially update on tmobile network would be extremely appreciated.
btw I'm in the US and my model is SM-G965U
-Craig
--UPDATE
I have researched a bit and found that it IS possible to change the firmware over to Tmobile using a patched version of Odin.
I downloaded from
https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
the 3.13.3_3B_PatcheD.zip
I downloaded G965USQS7CSK3_G965UOYN7CSK3_TMB.zip
from sammobile, which is for Android 9
I would love to be able to use HOME_CSC but that may not work. I could really use some hand holding going through this process.
Is this the correct firmware? Should I be using Android 10 firmware if that is ultimately what I want? HOME_CSC or no? I notice they have the 10 version:
PDA G965USQS7DTB1
CSC G965UOYN7DTB1
as well, which is Android 10 for Tmobile. Also, knox ? will this trip the knox counter thing-a-ma-jig?
Thanks

ok, so I bit the bullet and decided to go ahead. I used
odin 3.14.1_3B_PatcheD.zip just to be sure
I made sure my phone was unlocked: yes it changes carriers if I put in different sim. When in Tmobile sim Settings->Connections->Mobile Networks->Network operators , yes it has a search networks button and it eventually comes up with other carriers so....safe to say I had unlocked phone ( but not samsung unlocked ie. SM-G965U not SM-G965U1)
I used the latest android 9 firmware. and I used HOME_CSC ( even though I did a backup with smart switch b4) Everything went smoothly, and I still have my apps and now I can get an ota security patch for it. Will write back once I am up to Android 10. oh, btw I am still at SW ver Tmb/Tmb/Att , but I've got ota updates so I don't care

I am now at the same baseband version as my mom. Everything worked perfectly. I suggest you go with the least change possible to get to the point that you are able to do OTA updates. For me this was going to the latest Android 9 that they had at sammobile since I was on Android 9 and going with the Tmobile version. I hear the carrier doesn't even matter these days, but I decided I wanted to make sure it was Tmobile compatible so I chose the Tmobile version from sammobile. Happy trails to you in your endeavors. Hopefully you can learn something from mine.
Hey, I really want to thank you for this! I had the same issue and was exploring similar solutions. After several days of researching alternate plans, I was about to give it up as too risky until I found your post - by googling for hints: "SW ver. TMB/TMB/ATT"! You helped me take the dive, and I'm now happily past having a second-hand S9 (sm-g960u) that wouldn't do an OTA update. After a flawless flash, my first OTA request got me to Android 10, (UI 2). now I have a follow-up update scheduled for the wee hours. (And, yes, I'm still at "TMB/TMB/ATT".)
Perhaps like you, I started by investigating the possibility of flashing the UNLOCKED ("U1") firmware. After learning it was possible with the _patchedD Odin, it still scared me enough that I decided on a more conservative approach and followed your exact advice. I especially appreciated your plan to flash NOT the latest update, but the last Android 9 TMB update. That turned out to correspond to the ATT version on my phone, making TMobile either unable or unwilling to offer an OTA update.
History: This is my third used S9. While all were sold as UNLOCKED, only the first had the "U1" model suffix (SM-g960u1). When the second one booted up as a TMobile phone, I felt tricked - but also lucky that I got the right carrier. That's when I learned about the difference in model numbers. As you noted the U1 firmware is factory unlocked - attached to no carrier. When my third phone booted up with a Verizon greeting I figured I could be facing trouble - even though it accepted my TMB sim card.
The seller explained to me that my phone was part of a batch of ATT phones, all "SIM unlocked" using a Verizon sim card. I think sellers of phones with claims to be unlocked should be required to specify whether FACTORY or SIM unlocked.
Hope this great contribution of yours will continue to help others.
