Best I know is am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://27663368378

Then ETC-->Common-->Information-->Band/FGI/CA Info.

Also, what I've done to make my life easier is:

1) Download material terminal

2) Set initial command to "su" (understand the risks of this step first)

3) Enter all my frequently used dialer codes as favorite commands in the following format:

echo "<code>" && am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://<code>

I put the first part in so that I can see what code each entry is in the favorite command menu.

This makes my life *very* easy.

Oh and leave a blank line at the end of the actual favorite command to auto execute when you select it.

Hi. I'm very new to this mod thing so don't get frustrated if I aska dumb question. I bought a N9500 model cuz I prefer SnapDragon to Exynos. Is there anyway I can just swap CSC to either Thailand or US version without root? I still need to use Samsung pay and any knox related software.

Another thing is the Samsung keyboardon my model has a globe icon instead of sliding spacebar to switch languages. Is there anyway to change that? I attached a screenshot too for reference.

Last, for some reason my N9500 doesn't come with Samsung pass. I have to sideload it. But it won't work. after signing in it keeps saying Samsung passis temporary not available. Please try again. I tried to factory reset but it still won't work. Not sure how to fix it. Thanks guys.

Tomorrow I will dig into the bootloaders and compare between the F, N, and U variants with WinMerge to see if that will finally do the trick. Definitely would make sense at this point since I'm not seeing anything in the system partition that is missing or wrong now.

On the CA note, per the slow LTE thread I checked my Tmobile Note 5 and Note 8. They both have the same 12 combinations available.

makes no sense why they have such drastic speed differences.. perhaps as you say, the antennas are **** and bad boards

So...

Hey guys, as a chronic early adopter and someone with an S8+, I was trying to decide whether to go with a Pixel 2 XL or a Note 8. Decided to start with the Pixel 2 XL, knowing I had 14 days to return and that if I got the Note 8 it wasn't enough of an upgrade from the S8+ unless I sprung for the 256GB N950N version. Well, Google just made it pretty easy by not only having the microphone die 4 days after having it spontaneously, but now apparently having burn-in issues (or so a number of people are starting to say). I expect more for my $1000.

But reading through this thread, I'm really not certain where thing stand in terms of using a rooted N950N on T-Mobile. It's all a bit technical for me and I swear I keep getting lost without clarity on whether this is "resolved".

So the question is, for Kalm, or whoever else is: is speed still an issue for the N950N on T-mobile, or do you guys think it was simply a bad board that Kalm got? Anyone have the N950N working flawlessly on T-Mobile?

Thanks, and sorry if this is a thread hijack - was just trying to get clarity on the resolution here. Feel dumb that I can't tell! Haha.

[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
I can't give a definitive answer here but as far as I can tell, all the features are "functioning" on my phone now. The only thing is that the theoretical LTE speeds I should be capable of are much higher than I've tested personally, but I could just live in a bad area for T-Mobile (I have hit over 100mbps a few times so it's not horrible by any means). If I had a different tmobile phone, I'd test it out. But unless someone wants to ship me a tmobile note 8, that's probably not happening soon :P

What I can say is:

1) While I may not be hitting max LTE speeds, I find what I'm getting perfectly usable, and it really doesn't negatively impact me. To be fair, I do have 1Gbps up/down fiber optic at home so . . . that could be impacting my judgment here.

2) Restarting my phone every now and then for wifi calling is not a huge hassle, and I'm still confident that [MENTION=4375750]Kalm_Traveler[/MENTION] et al. will figure out the fix eventually.

3) T-Mobile is currently in the process of deploying a new AWS band that this phone does *not* support. If compatibility with that band is important to you, this is not the phone to get.

4) This phone has 256GB of internal storage. I have a 256GB micro SD card in this (and a 400GB card micro SD was just released by SanDisk at a *very* reasonable price) which brings me to *half a terabyte*. The display resolution/ratio on this phone is just fantastic, not to mention the quality of the display itself. It has amazing battery life (in my experience) considering it has not the biggest battery out there (smaller than the S8+, but lasts longer than the s8+ out of the box). I could go on and on and on but basically, it feels pretty damn good having a phone with these specs.
[Samsung Galaxy Note 8 Questions and Answers] minhajmsd:
When you buy an unlocked phone (especially international) and use it on T-Mobile it lists the phone as GRAY PHONE - 4G in their systems. That means that you are eligible for features like LTE/VoLTE and probably Wifi calling but you may not be able to get special features like full carrier aggregation.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Mine was working flawlessly for the first week or so, even after a CSC patch. I am confident that whatever went wrong with it can be fixed, and definitely that at least I (if not others) had a board that went bad on me. If I can get some time this week I'll try resoldering the antenna connectors again with a new better soldering iron and see if that doesn't do the trick. After the mic stopped working, I baked it in an oven at 450 F for 30 mins and the mic came back to life so I really feel like quality control was taking a nap when my phone was being put together.

Currently mine shows up as UNKNOWN with a ? icon on my account, and my mom's AT&T iPhone 5s shows up as an iPhone 5s (we're on T-Mobile remember).

I am pretty sure the bootloader files/settings are the key to finalizing this patch - so I just need a little bit of time to run a compare and build a new patch with the differences to test. I took Wednesday off work this week so I should have a few hours to get 'er done.

As far as "is the phone ok with T-Mobile" , from a technology standpoint yes it's great with T-Mobile. Anything that would make it worse than say a Note 5 (I use this example because it's essentially the same hardware, just older versions) is going to be software-related or something physically wrong with the hardware.
[Samsung Galaxy Note 8 Questions and Answers] minhajmsd:
Yes, the phone is definitely compatible with t-mobile and all of its technologies. As far as the phone showing up as "unknown", that comes up on mytmobile while it shows up as GRAY PHONE 4G in their internal systems. The iPhone 5s in the US is the same model across carriers so that will be recognized. I was just relaying some info I know from my time as an intern with tmobiles engineering team.

@Kalm_Traveler do you mind checking out this menu (that I mentioned in the other thread. Use secret code feature in samsung info app and open FIRST "IMS Settings" option (should be 467) but using TMO CSC and screenshotting every menu and submenu before playing around with it? I'm REALLY curious to see what these options are set as with a TMO CSC flashed but I've already screwed around in my settings so I'm not sure if I'd be getting pure TMO settings if I flashed back.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Yeah I can double check , that's a lot of screenshotting :)

Most of those settings are automagically set by the IMS profile itself, but like I mentioned on that other thread I think all the extra features can be used without changing CSC's entirely, except TMO wifi calling

It would seem that WiFi calling is not enabling anymore after a reboot. I'm currently running IronKernel too. Ideas?

[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
I just added everything that was 'missing' from the F ROM on that version just in case - the FB apps have been removed but I haven't uploaded a new version of the zip since I was waiting for the final piece of the puzzle. I expect to have it tomorrow since I took the day off from work.

Not sure honestly, since I'm a bit surprised it's been working that way for us for weeks. Maybe re-apply the T-Mobile zip?
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Remember I've been flashing back and forth between the tmo and your skc zip. I don't think my phone has gotten to 3 hours without a fresh tmo flash today :P

Sidenote, can you send me your QS icons with the tmo zip? I have two hotspot icons now and I could've sworn it never did that. I'm 99% sure I'm missing a different icon...

I know but I have two hotspot icons... trying to figure out what's wrong if there is something wrong because i don't remember there ever being two hotspot icons.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Haha you know what I do too, of total available icons.

I'm going to get cracking on the bootloader comparison in a bit, so I'll check the CSC entry for icons and see if that one is repeated. I didn't go through everything when i was using the original as a base so it's possible that this is just how TEKHD's file was to begin with.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
ok so I took a quick look at the boot images for the F and N with Winmerge, these are the only 'different' files (and the N doesn't come with init.rilepdg.rc but it appears to be created anyway because I have one and I certainly didn't put it there myself).

I'm not concerned with the different binaries as those are identical size and with the /system/ contents all seem to be the same aside from a different compile, or have the F product name in them instead of the N product name. The files I am interested in are the text files at the bottom directly in the /ramdisk/ folder.

Forgot to mention, in the screenshot F on the left, N on the right.

May be that we just need to either flash those as well as the CSC, or repack the bootloader and flash that with them included (including the init.rilepdg.rc of course).

Also going to try that EFS clear from the other thread just to see if that magically fixes my lack of reception and awful data speeds, but this wifi calling is my main priority since the only time I 'need' good LTE data is if I'm using Google Maps to direct me while driving. If we can get wifi calling working 100% correctly I can wait on getting the LTE fixed.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Best idea I have here keep changing IMS settings and dump file lists one directory level at a time sorted by last modified date, take the top subdirectories that appear consistently, and repeat inside those, over and over until you've narrowed down the file...

Otherwise, I have no idea where that file is.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
ok luckily work is slow today so I took a look through those files, init.rilcarrier.rc and init.carrier.rc are completely different between the F and N. While I am not 100% sure if this would make or break the wifi calling, the fact that they are not at all doing remotely the same thing definitely makes it a possibility.

Example, for init.rilcarrier.rc the F version is:

# Copyright (C) 2012 The Android Open Source Project
#
# IMPORTANT: Do not create world writable files or directories.
# This is a common source of Android security bugs.
#

# only qcom's chip would get this service enable

# MPTCP redsocks
service redsocks /system/bin/redsocks -c /data/mptcp/redsocks.conf
class main
user system
group system net_raw net_admin
disabled

while the N version is:

# Copyright (C) 2012 The Android Open Source Project
#
# IMPORTANT: Do not create world writable files or directories.
# This is a common source of Android security bugs.
#

# only qcom's chip would get this service enable
service diag_knight /system/bin/diag_knight
class main
user root
group system radio log
disabled

on property:ro.dmlogging.enable=1
enable diag_knight

*EDIT*

What's more strange is that I have the F versions already, even though I am on a stock N base currently....
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Where did you see eris mentioned?

nvm that is the 'missing' ril.epdg file - which once again strangely I already have even though I am on an Odin-flashed N950N base again.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
yep I was right there are 2 listed in there, hotspot and wifi_hotspot
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
ok so tonight I reflashed full stock with Odin, this time making sure I got rid of the 950F bootloader (which I didn't realize until today I still had) and in agreement with [MENTION=6170708]jooniloh[/MENTION] found that even without any CSC for T-mobile you can manually enable the IMS settings which gives VoLTE and RCS, as the profile info is already there.

On that fully stock setup, my LTE signal strength was still about 10db worse than the Note 5, but data speeds up and down were vastly improved - which is a good thing in that my phone isn't a lemon. On the flip side, I re-applied the latest version of my T-Mobile CSC patch (slightly reduced in size from the one in my sig), and what do you know, much slower download speeds, data connectivity errors on upload attempts return.

On full stock I was not getting any Carrier Aggregation, nor any listed combos in the Service Menus. With TMB CSC again I had the usual 12, and this only further strengthens the suspicion that there's something wrong with how the 950U TMB CSC is handling CA with our modem.

However.... this brings up a good point since I have screenshots from 9/21/2017 where I still had crazy good data speeds, but was on a T-Mobile CSC, so all hope is not lost. That was before I made my own fresh pack with 950U T-Mo files, so it was either TEKHD's S8 pack or that S8 CSC Selection tool, in either case we have both so this means i can rebuild my zip with those files and we should be good on that front.

This does not, however, help me get any closer to wifi calling working properly on the N base since I've been running N base on top of an F bootloader, and the latest patch version adds in all the files that the N is missing which the F has built-in, but the wifi calling icon disappeared after initial zip flashing, and only works if you reboot. Once wifi disconnects for any reason, the wifi calling won't reconnect again uniless you reboot the phone.

However, since this is definitely contributing to crap Carrier Aggregation I am going to fix that (possibly with the S8 files) and keep looking for the missing piece to get wifi calling working correctly without needing to flash an entire F ROM first.

So, not completely related but on topic with the "getting things that work on the T-Mobile phone to work the same on the Korean phone" theme, but discovered an interesting thing today. Uninstalled the Bixby vision app and reinstalled the version found in the Nemesis rom. Upon doing so, I go in to see that nothing is different and I'm still missing the shopping feature (when on tmo csc). When on Korean csc, nothing changes. I have shopping but it's through some Korean site, not Amazon.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Not too big of a surprise - the CSC has a region info piece. I really should try out Bixby one of these weeks... Makes me wonder if we compared the Bixby components between 950N/F and U if they are different? Maybe you need the 'murican version?
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
No that's the thing. Bixby vision's shopping feature is reported working on nemesis rom. It should work with tmo csc if the Korean csc is the only thing affecting it.

[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Not sure off the top of my head but I know for a fact it works on stock tmo which is why I was looking for its apk earlier with no luck

---------- Post added at 06:46 AM ---------- Previous post was at 06:36 AM ----------

Just tried an apk from online still doesn't work. Literally nothing changes. Don't think it's the Bixby vision apk at this point but another app somehow
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
I have the full 950U T-Mo version from Sammobile for making this accursed CSC pack. I'll double check it against the other two, but don't get your hopes up. Often times regional functions are due to settings hidden away somewhere and the actual apk is identical.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
You mind zipping up /system/app and /system/priv-app and uploading it somewhere?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
sure, for N and U?

*EDIT*

Things are not looking good, here is a comparison of the N and U variants. The apks are 'different' but this looks like just the typical "different build of same core".
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Well like the weather app automatically stopped using the Korean weather service and started using accuweather once tmo csc was flashed. What other regional identifiers are there and is there a way to fake it?
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Might be helpful in general for other things.

Check VisionIntelligence.apk. That's Bixby Vision.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
that one the N version is 5 bytes larger than the T-Mo version. Yes bytes, not kilobytes. Keep in mind I deodexed the N and U variants myself so anything with this small of a difference is likely due to just how it was de-odexed.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
What's weird was the version I had on my system was like 8 mb where as the version I found online was like 38mb...

Also, really weird thing started happening.

Note, I'm on iron kernel. The last things i've done are: flash your skc zip. flash stock CSC in odin, clear EFS in odin (which fails), manually flash the cached zip in TWRP to complete the clear EFS operation, then (more recently), I flashed your TMO zip again. Haven't done much since then.

Just now I checked my phone and wifi calling was on, WITH the icon. I tried toggling it off and back on. It enabled again with the icon. I tried disabling wifi and turning it back on. It enabled again with the icon. I rebooted my phone. It's now stuck in enabling again.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Yeah both the deodexed N and U versions are 8.7mb

clearing EFS in Odin fails? I haven't seen that one yet. What usually fails is when you reboot and stock recovery tries to load a zip file that isn't there (or is there for some of you? it is missing on my phone at the moment).

Yeah today I rebooted and IMS won't register at all, so I have no VoLTE, RCS, or Wifi Calling. Rebooted twice and nothing. I'm going to do that full factory flash back to stock in a bit and stay on that for a bit until I'm not on-call for work next weekend. Since full stock you can just manually turn on the IMS settings which gives VoLTE, video calling, and RCS plus has good LTE speeds I'll just deal with it for a week.

Next weekend I will have a bootloader mod script ready (to add the 1 missing file from the F bootloader) as well as a setting addition, then try to flash the S8+ files that everybody else has been using for their T-Mo CSC packs. One thing I noticed in the T-Mo files today (just looking through some settings files) is that the 950U system/vendor/carrier/TMB/build.prop sets the LTE default network type to 20, where the S8-based T-Mo packs set it to 9. Now... we can't set it to 20 in our service menus, it only goes up to 10.

Not saying this will solve all the problems but i'm wondering if that might not have something to do with the flaky CA behavior.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
No my wifi calling enabled again. I just had to wait.

Clearing was failing meaning it's odin that passes that command to recovery and that command fails. Hence the manual zip flashing. Not talking about anything we haven't already established here.

As far as I can tell, everything is working other than the CA issues.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Very strange, I hadn't seen that discussed yet - the only thing I have seen was something I see as well where you reboot after Odin'ing back to stock and stock recovery tries to 'install an update' but fails saying it can't find /cache/recover/sec_omc.zip (in my case it keeps being deleted beforehand, so I just manually put it there when preparing to full Odin flash).

I flashed the SKC zip because VoLTE and wifi calling suddenly stopped working and wouldn't come back. VoLTE is working great now with IMS manually turned on (per your finding that this works), and as expected my data speeds are nice and fast again.

I'm going to spend this week making a bootloader mod to add the 1 missing file from the F, and some minor tweaks to init.rilcarrier.rc and init.carrier.rc (basically combining them since they have entirely different contents) and make a new T-Mobile CSC zip from my Note 5's files. I can't imagine that anything from it would have problems on our Note 8's since it is all the same family of hardware, and there's nothing it supports that our 8 doesn't.
