sure.. everything you need is in that repo I created a few days ago

https://github.com/gundal/greatlte

clone the repo, grab the ramdisk folder, in there you will find unpackimg.sh and repackimg.sh

you just do a

./unpackimg.sh boot.img

and it unpacks for you... you will need a linux based system however.

ubuntu on a vm or something. otherwise send me the boot.img from the U (tmo firmware)

and I will extract it and upload it to the repo also, then you can just look at the extracted files without linux
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
ah thanks! I will check it out after work tonight. I run a Ubuntu VM at home for these Android projects, should be good there.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
So i just got home, wifi calling took about 2 minutes for the icon to show up.

On another note , i've noticed that signal can be 100% and LTE is available, but there's zero data throughput. I've had several apps advise me data network is unavailable while i have full bars.

What do I need to do? I'm not familiar with the mimo convversation or how to take advantage of it but this can become an annooyance
[Samsung Galaxy Note 8 Questions and Answers] gundal:
SO after realizing my WSP is restricting access to ims services based on imei and device origins.

I started a complain with the CRTC..

it was accepted as a valid complaint in violation of the CRTC CODE and my WSP was given 30 days to resolve it...

The office of the president for rogers just called me, and gave me the exact same song and dance, its impossible to whitelist your imei or to force provision your account

the system will automatically deprovision ims services from any account that does not have a valid rogers device connected.

Said that was rogers business decision and it was not going to change...

Then.... she offered me a note 8, rogers branded, to alleviate the problem (a swap of mine, not a free device)

I then explained it was the exynos version, with 256gb and I did not want a RWC device, I just wanted my device allowed to use their services... and that I am rejecting their offer and I will let the CRTC rule and dictate their actions in violation of the code, then they can change the system to allow any device.

she then said she will contact tech dept one more time and find out if we can find a way to force provision the system, then she will get back to me.

LOL.. give me a phone and get me to shutup and let the monopoly bs continue??? Not happening.. ill let the CRTC FORCE them into changing it.. or if they provision my account, ill just post everywhere I can think off to show others how to get this changed, and STILL get the CRTC to force them into changing this BS policy.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
very nice, i wish we had such consumer protections in the US...

Where do I find the MIMO settings on my korean version ?
[Samsung Galaxy Note 8 Questions and Answers] gundal:
doesn't the FCC regulate things in the US much like the CRTC?

for the MIMO settinsg you need to:

-have root

-download shortcut master lite

-open shortcut explorer

-run code 27663368378 with Method 0 (root)

in that menu goto

3 ETC -> 3 COMMON -> 6 ANT TEST Setting -> 5 4x4 MIMO/256QAM
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
thanks. 256qam was disabled , i enabled it, not sure what to expect

And FCC doesn't get involved in the peon's (that's us) petty squabbles.
[Samsung Galaxy Note 8 Questions and Answers] gundal:
whoa wtf...

3 ETC -> 3 COMMON -> 6 ANT TEST Setting -> 3 MAIN ANTTENA TOGGLE... MINE WAS DEFAULTED TO OFF?!?! anyone else??

Just turned it on so far no differences

---------- Post added at 12:11 AM ---------- Previous post was at 12:10 AM ----------

256qam being off means you will not see the + next to LTE or 4g.

you can disable see it doesnt com back, enable, and watch it come back I tested that the other day

you also want to check the 4RX Diversity selection.. for 4G. that should be the default (CA+4RxD)
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
main antenna toggle for me was off too, enabled it.

Also itw as already on CA+4RxD)

I'm curious are S8+ Korean N users in the states having this problem?

IF not , then what is the difference?
[Samsung Galaxy Note 8 Questions and Answers] Kamikaze_Ice:
Rogers.... that sound just like how AT&T act (bribing customers for silence over the stupidest things (i.e. to lazy to authorize one persons device on their end).

At least with AT&T the majority of their CS reps don't know and will enable it for you. Just gotta call and imply that you were basically told on their own forums, of unofficial tech support lol, that provisining the device's IEMI/IMEI/EMMY/iMAY works for other customers.

I'd love to not have to act stupid to get things done here. Telling the City that flash was insecure and their software had a secure HTML5 mode was fun. They tried to get me on "hacking" their website. Gotta love southwest Missouri. (It was Avolve software, and they did bare minimum changes from default "example" settings! City was still "forcing" people to use Internet Explorer and Windows XP computers even after MS stop support...)
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
I'm gonna go ahead and confirm that whenever there is a demand for data download, i.e. downloading ROM on your phone, the signal will drop completely several times. I repeated this behavior back to back 6 times today so far. This also includes during speed tests.

I'm on notorious kernel and nemesis rom. gonna flash Ironkernel and see if it makes any diff, i doubt it will though
[Samsung Galaxy Note 8 Questions and Answers] gundal:
i suggest you backup your data in twrp. do a factory reset from android then restore your userdata and test your connection.

That restored my CA working by default.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
k i will do that right now
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
1) The bandwidth drop when data is requested is due to CA being triggered at that point. The first second or so of your download is on the network you were connected to. the speed drop ties perfectly to (at least on my device) the moment it starts cycling bands. IDK if carrier aggregation is supposed to do this, but that's the behavior I see on multiple LTE tools as well as *#0011#. tested this a billion times using service menus, various apps, and various speedtest apps; as well as doing all sorts of combinations of LTE band locking/band disabling, etc.

2) Literally just posted like 3 pages ago that main antenna toggle was off. It's supposed to be. Doesn't affect anything.

3) I tried factory resetting from android, but that made no change to the CA behavior (constantly cycling the moment data is requested). Also my icon (see earlier post) has never gone back to what it used to be (which is the part that bothers me the most, considering I did a full restore in TWRP)

4) for anyone who prefers doing things by hand, rather than using a service mode tool, you can just su in a terminal emulator, then run "am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://27663368378".

5) There are laws in the US preventing carriers from actively disabling features due to phone region. That doesn't mean the carrier has to natively support features on every phone variant, nor that it's the carrier's responsibility to help you mod your phone to enable said features. It's not the carrier's fault if a Korean Note 8 doesn't come with the software to properly enable their wifi calling, volte, etc. That doesn't mean they're blocking it.
[Samsung Galaxy Note 8 Questions and Answers] tokoam:
On CA+4RxD I have it enabled but on info it just shows disabled .
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
thanks,

I can concur that android factory reset didnt do nothing. If anything i somehow gained an extra volte icon with what looks like two clouds swirling around each other (volte was off).

Is the F\DF\N models of the s8\s8+ having the same issue?
[Samsung Galaxy Note 8 Questions and Answers] gundal:
No here in Canada, rogers is legit blocking it. (actually the system automatically provisions the account and removes volte if the imei is not a known to them)

My voLTE works perfectly for 15 min after switching sim from branded device to non branded device.

then is cut off, if I put it back in my branded device it takes 15-20 mins then turns itself on.

The other day when I was super happy everything was working, I actually had volte for a full day.. I later found out they were running maintenance on half of their systems and thats why it didnt pick up the change and cut me off sooner lol..

thanks for the adb shortcut (wish that dialer code just worked..)

my complaint including this "method" of proving that the carrier is indeed deactiving and stopping the features from working.

It is not supposed to cycle like that, and does not for me, and you should see a +

also seems we have only 2 antennas.
[Samsung Galaxy Note 8 Questions and Answers] gundal:
is tmo FDD or TDD lte?
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Yeah on my phone it shows the CA:# like it should for carrier aggregation, but it's always at 0 until I request something (like run a speed test). Then instead of switching to like CA:1 or CA:2 and staying there, it goes back and forth between them and continues to do so until the data is no longer being used again. I know the service mode screen looks different on every phone, so I wasn't sure what CA was supposed to look like on this phone. I've seen screen shots from other phones where it actually lists every band out simultaneously.
[Samsung Galaxy Note 8 Questions and Answers] gundal:
you will see the secondary and tertiary PCI (physical cell indentifier aka tower) number for each signal connected but not each band. Sec.. ill post mine

Usually sit at CA 0 or 1, when I hit a speed test it ramps up to 2 then stays there until the test is done.

Maybe you dont get to see every tower and band, the tower below is same as above.
[Samsung Galaxy Note 8 Questions and Answers] minhajmsd:
Hi guys, I just got the 950N (KT variant if that matters). Is it possible to just flash the stock 950F image on this and the T-Mobile CSC? I have no problems with internet speeds with this but calls are taking extremely long to go through.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
What I'm saying is that I've seen screenshots from some phones where the service mode screen showed all the towers listed simultaneously with the bands too I'm pretty sure, and every phone shows the info on that screen differently so I want sure how mine should look when CA is working correctly. I'll do some more tests now that I'm outside. Maybe it won't cycle anymore...
[Samsung Galaxy Note 8 Questions and Answers] gundal:
That is my SM-N950N

earlier today I showed you the same scren from my note7 which showed individual bands.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
I'm not disagreeing with anything you're saying. I'm simply describing what I experience and pointing out that due to variation handset to hardest that I did not have enough information to reach a conclusion.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Also notice my lte icon has no plus as I pointed out before, yet CA was 2 and this lte app shows this:
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
using Kalm's CSC zip, it removes the LTE+ icon, i just tested it out, doesn't mean it's not aggregating though

What should these 4x4 mimo settings be ?
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Please read my previous posts regarding this.

---------- Post added at 03:32 AM ---------- Previous post was at 03:22 AM ----------

@kalm_traveler considering how popular this has gotten, you might want to consider modifying your first post with some information + the link to the latest zip. Unless there's another release thread I'm not aware of. :P
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
haha good point - I have been focused on trying to find the final piece of a fully functional patch, not paying enough attention to the first post :D

So when I come home from work I don't get the wifi calling icon, even though it is still connecting. At work I had it off and on all day (randomly, I wasn't doing anything to try and make it appear or disappear).
[Samsung Galaxy Note 8 Questions and Answers] gundal:
and I was just trying to show you our phones screen so you would have more info.

Well those speeds are disheartening.. is that a custom rom or the stock skt?

---------- Post added at 03:38 AM ---------- Previous post was at 03:36 AM ----------

I have the same default setup that you are currently showing, ive played with it a bunch but didnt seem to change much.

---------- Post added at 03:39 AM ---------- Previous post was at 03:38 AM ----------

after flashing the zip and losing the CA, is 256qam disabled by default in menus?
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
I have one test in the same area go 95 down but only 4 up. Haven't had uploads over 25 yet. It's stock running this patch. Although (as mentioned in a previous post) I had to reflash stock from a file I downloaded from sammobile and it turned out to be an SKT firmware someone uploaded as KT. Though as kalm pointed out, that may not matter as these are multi CSC.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Also, in the same area I took this speed test right under 4 towers according to the same lte tool

Edit: it shows I'm under 4 towers on the map tab that's not shown
[Samsung Galaxy Note 8 Questions and Answers] gundal:
When you fIrst had the phone before flashing anything did you get better speeds?

I have downloaded all three of the n950n firmwares, they are all 100% identical with the default being SKC. As palm said they are multi and have skc/luc/ktc.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
I don't even know what to think anymore I'm in side of a Walgreens where the screenshot was taken the last three or four tests where they were all above the normal speeds were used to.

This is using the CSC settings inside renovate ROM.

At home with my T-Mobile Note 8 I was getting the same speed but with my Korean Note 8 at home I'm not getting the same speeds.

Yet here I am sitting in Walgreens trying to upload a screenshot of this and it's telling me upload failed none of this makes sense

Edit: I couldn't upload the screenshots until I got back on my WiFi at home
[Samsung Galaxy Note 8 Questions and Answers] gundal:
that must be super frustrating.. I do not have those issues at all on rogers network.. and I always thought they ran the same freq as tmo, in earlier days the T rom would always be the one that was compatible with our canadian W8 devices from n3 and up..

For you guys that are getting **** signal I would suggest trying to flash the F modem and see if it helps. There is also the ability to disable bands individually. so its very possible one or more of your bands has the right frequency but a diff implementation and perhaps the device cant use it but thinks it can, disabling that freq would let you ignore it.. you guys should make a log, of which bands get what speeds etc.. etc..

to disable individual bands its that same menu we all love, in ant setting goto

Antenna Switching -> AS TEST - > 4g-> Enable test mode - > Test mode -> band setting -> turn on the ones you want.

on a side note... I think I figure out how to trick the system into letting me keep volte ! its been on for an hour now.. so either a maintenance or adding an invalid apn for ims to override the existing one and stop it from updating is working!
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
ill play with individual bands and see what i achieve.

If i flash a F or U modem will it brick my device if i'm on a N device? and where are they located ? i'll happily be the guinea pig
[Samsung Galaxy Note 8 Questions and Answers] gundal:
no. its sooooooooooooo fu-CK-ing hard to brick your device for good.

but dont flash a U modem, thats a qualcomm modem and 100% will not work, the F has a great shot of working.

always worst case, you can get to download mode and flash yourself back a stock everything and you are saved, and if you put your TWRP backup on microsd card even if you had to smartswitch back to stock, you can then install twrp and just restore your current state.

the modems are not anywhere readily available, you need to extract them from the stock images.

I will try and do that for you tomorrow if you havent found another way.

---------- Post added at 05:17 AM ---------- Previous post was at 05:09 AM ----------

can you guys please confirm tmo's lte network bands and frequencies

T-Mobile	2, 4, 12, 66, 71**	1900, 1700 def, 700 a, 600

bold being main ones

Rogers has 4, 7 and 12..

so try to enable just 4 and 12,
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Didn't test as thoroughly but from my memory, no, not really.

---------- Post added at 05:26 AM ---------- Previous post was at 05:25 AM ----------

Instead of going into test mode, it's a lot easier to just *#2263# lol
[Samsung Galaxy Note 8 Questions and Answers] gundal:
!!! theres so many codes haha thanks..
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
T-Mobile primarily uses LTE bands 2, 4 and 12. In my area I'm usually on band 4 but driving around some spots switch to 2 or 12.

My speeds out of the box were much much faster than they have been since about 5 days after opening the box. Honestly i am half tempted to order another one to keep as a spare and leave completely stock just to compare.

Although, as I've stated already mine most definitely has a physical reception problem. Unplugging the antenna wires should drop the signal strength but it doesn't change at all (it's already not benefiting from being connected to the lower PCB so disconnecting the wires does not make it any worse).

Soon as I can buy a replacement I will know for sure.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Did just that. Left 2,4,12 enabled after accessing test mode I rebooted and now these are the only bands selected.

And I am now about to upload attachments on T-Mobile network to xda app
[Samsung Galaxy Note 8 Questions and Answers] gundal:
So is slower.. But doesn't cycle on and off?
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
No. Not slower. At home I was getting sub 11mbps. Now it's almost more than double.

Question is did the change I made permanent ? Because it won't let me back into that test mode, only band settings
[Samsung Galaxy Note 8 Questions and Answers] gundal:
Use the code joon showed. It is without test mode

Sooo this is weird.... But flashed iron kernel, and I'm still stuck on enabling. But even weirder... Swiftkey is like 50% larger on all sizes now..... Wtf?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Yeah like I said at home I still need to reboot, but at work it will connect without a reboot. I should have time this weekend to do more research (full time work + full time school does not leave much time to finish this patch).

Why would the kernel affect SwiftKey size? The only strange behavior I've noticed with it was that for some reason the long press popups are tall rectangles now instead of squares, and on the Korean layout the long press for ㅋ changed to a red heart image: ♥ with an outline heart as it's other option: ♡
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
No idea. I've gone back and forth a few times now to be sure. Notorious: Small SK, Iron: Huge SK. Every time.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Does this seem right?

I'm not in the UK obviously
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
No, it looks like your sales_code.dat still has the original CSC code in there. It should show the region as USA, and active CSC as TMB
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Thanks, I fixed it. by flashing ur csc, just gonna use it from now on, since the icons make little difference to actual behavior.

Side note: data connectivity while on phone calls is more reliable than LTE connectivity when i'm not.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
[MENTION=4375750]Kalm_Traveler[/MENTION] any reason why others (not even going to attempt to mix my own experience into this as it makes no sense) are losing the + icon after flashing? Does TMO not use a + or is it possible there's an icon resource missing somewhere?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
If the CSC applies correctly, the icons will change to what T-Mobile uses, which does not include the default LTE and LTE+ icons.

T-Mobile will show a "4g/LTE" icon for any LTE connection regardless of CA being active or not. If it drops to HSPA+ it will show just a 4G icon. If you enable Download Booster the LTE icon will change to the letters "LTE" above an upwards-pointing Wifi icon.

In short, the icons should completely change with different CSC's applied.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
thanks for the education sir

I just activated a new sim, gonna takae a spin around town and test data speeds.

Side Q: I never recall seeing it on my tmonote 8 because i wasn't paying attention, but when on phone calls, data drops to HSPA+ is normal correct?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
It does that if you're not on VoLTE, has to drop to 3g (HSPA) to make the call. if VoLTE is connected it won't do that.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
I figured this was the case. Makes what I experienced make even less sense lmao. Well good to know that now at least I shouldn't see the + icon.

If anyone does want to test whether CA is working or not, without launching into dialer codes all the time, I've been using this app called Network Cell Info that gives you all sorts of in depth information, as well as indicating whether or not CA is working on the main screen. It also shows the location of nearby towers on a map and indicates which one you're connected to. I've also gotten some interesting information from the plots provided by another app called Rx Monitor. Network Cell Info has plots as well, but I like the one in this app better. Lets you track the strength of the various signals you're connected to. Used this with speedtest in multi window to figure out what was happening with the speed drops and such. Just thought I'd throw these out there in case anyone finds them useful.

---------- Post added at 12:49 ---------- Previous post was at 12:47 ----------

people always forget this advantage of VoLTE. It's not just the HQ calling. It's being able to stay connected to high speed data while on the call as well.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Got ya. I disabled volte because no one could hear me lol
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
VoLTE seems to work fine for me, but when I do wifi calls there is about a 5 second delay at the start of the call before they can hear me. I don't think this happens on my Note 5.
[Samsung Galaxy Note 8 Questions and Answers] minhajmsd:
Asking again, would I just be able to flash the files through ODIN or do I have to take any extra steps?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
No, it won't let you flash the F variant firmware because Odin knows your device is an N variant. You can flash TWRP with Odin, then use TWRP to flash a 950F-based ROM in a zip file, however.
