I hear ya... The Note 5 is a rock solid and quite frankly there is nothing wrong with it except the missing microSD. It's such a strong performer...

I've really began to appreciate how strong the Note 5's antenna vs other phones, not just due to this situation, but man...I'm connected on a VPN and the still yet the speeds on the Note 5 can school other phones not even connected to a VPN lol...

I really hope we figure this Note 8 thing out... it's a master piece and and the Note 8 is that good to where it'd be enough to retire the Note 5 (which I wouldn't sell lol... it's staying in the family.)

I think we're getting close....

If I had to give it my best guess, I think this is a situation where something within the code after a certain point goes haywire, kind of like how a computer bogs down after a while of being on for too long. Maybe there is a threshold and the phone is getting by just fine for a while, until the chaos reaches a point to where something is throwing it off for it to either work or not work. ie... software compatibility specific to what is causing this issue within the firmware / efs -> csc.

It drives me crazy to know how the Note 5 has an Exynos chip and works wonders lol...
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Yeah if i have time today I'm going to try using the Note 5 CSC setup (with its apps and libraries etc). It is on Nougat now so I'm pretty sure everything will work.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
i'm excited about this. It seems nothing we try from other Note 8's is proving 100% success rate.

Have u tried dr. ketans csc zip ?

It gives me

- decent speeds (14 CA Combos but CA hasn't activated and i got 62mbps on my couch , will drive around today and see)

- VOLTE & Wifi Calling + Caller Spam protection (which is removed when i flash ur csc kalm)
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
I've tried only that big S8 CSC Selection tool, TEKHD's S8 Tmobile pack, and my own iterations of one made with the T-Mobile Note 8 files.

Incidentally, mine actually does add the spam protection (I've been using it weekly as some spammer has my google voice number and keeps calling me from similar numbers every few days).

Do you have an 950F or running an F-based ROM? So far, this is the only way anyone has been able to get T-Mobile wifi calling reliably working on Exynos Note 8's. There are a number of vital pieces missing from the N variants firmware which prevent the existing CSC patches from making it work.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Getting carrier aggregation and good speeds now on Dr ketan CSC.

Yes I'm on f based ROM .

As u can see speeds sucked at first then kicked in

Carrier aggregation isn't working everywhere for me tho and I'm in a metro area
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
ah yeah makes sense then. With any F based ROM any of the T-Mobile CSC solutions floating around will give VoLTE, Wifi Calling, video calling, etc since the underlying components are in place.

I'm not sure why you would have lost the spam calling since that is just part of the CSC features. However, we have determined that something in the 950U files (which is what i used to make my zips so far) is causing the Carrier Aggregation to not work properly.

The first CSC I used was that giant S8 Multi Selection tool from the S8 forums, and applied it to my factory 950N base firmware. Got VoLTE and video calling, and kept the super fast data speeds but of course wifi calling wouldn't work since it was missing base libraries and apps.

The reason I want to try making a T-Mobile CSC pack with entirely my Note 5's files is that it is both Exynos and T-Mobile, as well as being on Nougat now, also having the same type of modem as our 950N (albeit a slightly older version). This makes me think that it has a greater chance of working out of the box on top of N firmware.

also notice you are not on a T-Mobile CSC, you have the stock LTE icons?
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Alright sir I'm down to test I am excited hoping we can replicate what your seeing on your N5 !

Also anyway I can manually enable volte and wifi calling toggles
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
you need to find the tag in csc_feature.xml or others.xml in the OMC folder for the CSC you have active which starts with

<CscFeature_SystemUI_ConfigDefQuickSettingItem>

and in there add VoLte and WifiCalling

Example, the one from TEKHD's Tmo pack is this:

<CscFeature_SystemUI_ConfigDefQuickSettingItem>Wifi,SilentMode,MobileData,Flashlight,RotationLock,Bluetooth,Nfc,Location,AirplaneMode,PowerSaving,Aod,WifiHotspot,BikeMode,DormantMode,BlueLightFilter,SFinder,Ebook,Cast,Cellular,ColorInversion,DefaultData,DeviceVisibility,Dnd,Intent,RedPacket,WifiCalling,AllShareCast,PersonalMode,VoLte,UHQ,TouchSensitivity,SmartStay,Toolbox,Sync,MultiWindow,UltraPowerSaving,ScreenCapture,UDS,Hotspot,QuickConnect,POWERPLANNING</CscFeature_SystemUI_ConfigDefQuickSettingItem>
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Did this and no toggle is appearing
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Did you reboot?
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Yes but I'll reboot again just in case

---------- Post added at 11:46 PM ---------- Previous post was at 11:44 PM ----------

Just rebooted again. No toggle. I do have the option enabled in settings too
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
While on the subject of quick settings. What's the difference between Hotspot & WifiHotspot aside from the obvious in the name. Also is there is a difference between Dnd & DormantMode?

Ever since I flashed Kalm_Traveler's TMO Mod I have 2 "do not disturb" toggles & 2 "mobile hotspot" toggles. I'd like to get rid of the duplicates if possible
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
to be fair, ive had two do not disturb's on every ROM i've flashed except for stock, even if i don't flash kalm's csc (not sure what is causing it, could be the ROM's csc, could be dr. ketans csc could be TKKG S8+ modified csc zip)

I want to get rid of them too.
[Samsung Galaxy Note 8 Questions and Answers] DeeXii:
How are your speeds?

Are they still good?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
I flashed the SKC CSC zip I made for [MENTION=6170708]jooniloh[/MENTION] over top of my smorgasborg setup (950F bootloader, 950N base, my T-Mo zip) and as expected speeds are right back up where they should be.

For the record I have to thank everyone who said I was wrong about it being a software issue - and now need to dig into this to figure out why the T-Mo Note 8 files cause this weird data speed/connectivity issue, but the S8 and S8+ files don't.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Depends on where I'm at.

I should be getting excellent speeds where I am but alas
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
funny the previous pics i posted are from band 4, im home now and my phone is on band 2 getting 45mbps.

Remember i don't have the CA set up on my phone right now. Stock CSC is SKC , active CSC is XAA (US)

Can someone send me the skc.zip

[Samsung Galaxy Note 8 Questions and Answers] masri1987:
On the note of US CSC's, when using Dr. Ketans' CSC, it adds Device Security to the device maintenance tool. i'm on simple rom and it usually doesn't have the mcafee security nonsense. but i flashed the csc and i had it all of a sudden
[Samsung Galaxy Note 8 Questions and Answers] Kamikaze_Ice:
I finally figured out what was causing my problems with my unstable 5GHz wifi connection.

It was Magisk (no modules).

I have no idea why Magisk caused issues with VoLTE instead of simply working or not working.

Switched to SuperSU and have had no problems at all.

I've flashed back and forth and the results are always the same (Magisk giving me greif, SuperSU remains Super).

Perhaps this may be useful to someone here.
[Samsung Galaxy Note 8 Questions and Answers] Techvir:
Can I request a RWC ( rogers Canada CSC )for flashing, please ? I flashed a moded version of CSC selection tool for s8 but my signal seems to be all over the place on my note8 Sm-N950F

Edit: I am having the same issues that everyone in this thread has with the N950F version but using it on Rogers
[Samsung Galaxy Note 8 Questions and Answers] tokoam:
I'm getting ca2 on att using renovate Rom. I was only getting ca1 before on other roms don't know why.This thing has a mind of its own.Also the + next to the LTE icon comes and goes its never consistent even tho I am getting ca.This is in my apartment.One would also think the phone and or cell tower would stick to a better signal I get better results on band 17 yet it always goes back and forth between 5 and 17 and even if I set it to preferred in service mode.Also another interesting point is when i select a manual band on its own I loose CA all together I have to keep it in auto mode.
[Samsung Galaxy Note 8 Questions and Answers] DeeXii:
Im kinda confused with keeping up with this lol. Plus I have been helping my inlaws move since Wednesday, oi.

So is this resolved? o.O
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
I've been running Magisk this whole time and using VoLTE with no problem (not getting toggle but everything else works)

No resolution still.

Also using Dr. Ketans CSC for TMB is forcing a weird APN and giving me mms issues so i had to abondon that setup too (adding T-Mo APN and selecting it as default doesn't stick)
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
i think i've odin flashed my phone about 20 times at this point, and i'm losing my mind, every time i flash Dr. Ketans csc, or kalms tmo csc, or even tkkg1994 csc that i modified to make it work with N8, i lose features, whether it be toggles, or spam \ caller id protection, can someone provide a complete breakdown on where these items are located in the CSC and if there's a tool or utility that will edit the CSC for us and ensure these features aren't lost?
[Samsung Galaxy Note 8 Questions and Answers] Kamikaze_Ice:
I think "enforceskippingpackages.txt" will disable some packages. I have to modify this so I keep Microsoft apps (Word/Excel) for business reasons.

I have no idea as to the function of this list, but there are two of them in different places depending on rom/csc. (/system/etc and /system/omc/<carrier>/etc).

There are other CSC features, and mostly the more useful ones, in the cscfeature.xml, cscfeature_network.xml and customer.xml.

I've been playing around with them when I found out Magisk was causing my problems (VoLTE was very flaky but did work. Works much better with SuperSU).

The Note 8 has encrypted cscfeature.xmls which is probably why you have all had to play the guessing game trying to get things working (they could be different than N5/S8/S8+ files but we can't compare them).
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
thanks for the info man, this is quite the experience, things were much more simple and straight forward in the past lol
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
I have an app called CSC Features Expert that allows you to see all the current CSC settings, but it doesn't seem to be able to save changes on these encrypted files. Still, being able to view them is almost good enough.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Yeah I did that too in hopes of finding anything in regards to toggles and spam protection
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
I'm on my non carrier aggregation setup. This is such a disappointment and I'm in downtown Phoenix.

My home is not even in as good of coverage and I get up to 60-80mbps under same setup.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
And this is with carrier aggregation in the same exact spot.

Edit: I'm inside a doctor's office now , on band 12 back on my.non CA setup. Band 12 is so useless. Speeds are in the kbps
[Samsung Galaxy Note 8 Questions and Answers] Kamikaze_Ice:
Question:

Does everyone have root and/or bootloader is unlocked? I was thinking, which is a bad thing, that some carrier specific apks/settings may detect this and try to... for lack of a better word, punish us. Sort of like how carriers hate users with devices that were not purchased through them.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
pretty certain we are all rooted and bl unlocked, which apk's were u curious about? because the device behaves the same with either CA or non CA setups on stock rom...
[Samsung Galaxy Note 8 Questions and Answers] iunlock:
:highfive: All good and respect. We're all on the same team. Looking forward to figuring this out...fingers crossed...

Regarding the TMO csc, the answer to the elixir of life is likely in there...only if we knew what it looked like to be able to copy/paste it over and to flash it to our N and F models eh?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Yeah I mean you can look at the CSC Features with that utility but there are a handful of other files. My hunch is that it is the tmb strings file because it appears to be binary so i have no way to know what it does. Everything else is fairly obvious and I'm quite sure not the cause. With the new zip of Note 5 files I think we'll see immediately if that's the issue.

My guess is that it is trying to tell to modem to do something that the Snapdragon 950U modem can do, but the Shannon modem that comes with Exynos CPUs can't. Since the Note 5 is also Exynos with a Shannon modem I'm betting that at worst using its files will give proper functioning CA at Note 5 speeds (which let's be honest is still much faster than most of us ever get or need for LTE).
[Samsung Galaxy Note 8 Questions and Answers] Kamikaze_Ice:
Sorry I was just sharing one of those strange ideas you get when sitting on the toilet. :victory:

I was thinking that potentially there may be some strange shenanigans happening behind the scenes, similar to region locking or having to wait a week or whatever to regain access to OEM Unlock, or even how some apps check for root like Netflix (can be bypassed AFAIK). So I'm assuming it's possible to keep something functional but not as well as it should/would when not rooted.
[Samsung Galaxy Note 8 Questions and Answers] iunlock:
Precisely and that's what I was thinking too in using what we know works form the Note 5 on the Note 8.

This would be a huge breakthrough if it works. One step closer.... :good:
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Have we given any thought that maybe we need the right amount of carrier combinations? I'm getting ca and decent to good speeds. Started over with Odin and flashed renovate rom

The picture of the speed test results, what's in red is where CA:2 was active.

Also, i didn't witness any signal strength dips and battery drain is normal.

I lost my non-CA set up when i wiped my sd card accidentally so i had no choice but to start over and get what i get, so this happened
[Samsung Galaxy Note 8 Questions and Answers] AndroidFantic:
From what I understand is that on T-Mobile they are using the 600mhz band which the note 8 unfortunately doesn't support. 600mhz allows further reach and better reception

[Samsung Galaxy Note 8 Questions and Answers] masri1987:
This set up is working nearly almost perfectly for me. CA is working inside the gym without any dropping of signal, how do i back up this setup without losing anything , especially in regards to the CSC\EFS ( i can backup efs but csc?)

LOL dude i didn't even watch the video he posted til now, wtf.

Have yall tried any of the new roms that popped up yesterday? Some of them come preloaded with t-mo csc, i wanna try but ain't risking it now lol

None of the roms actually change my CSC to Tmo and I've tried every one. It remains resolutely on UK unlocked through every install.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
that's interesting, because flashing rom's like rennovate or slim rom, has csc selection, altho it doesn't have t-mo, it has generic 310 country code selection options which is the US.

The new roms, specifically this one, per the dev, has t-mo csc built in.

Damn. Let him know
[Samsung Galaxy Note 8 Questions and Answers] krabman:
Not sure that it's rom specific because none of the roms that say they change it actually do change it. I'm wondering if our stupid OEM unlock impaired phones are having some effect on the CSC change? Roms otherwise seem to install fine and I've done all kinds of mods, changed the BL, CP etc. The CSC however seems to be a little reluctant to change.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
i've been able to change the CSC to whatever region i'd like using the modified csc tool from tkkg , he didn't modify it but you can modify a line to make itw ork with note 8

I've been reading those threads but I don't need any provisioning, I use Tmo because their overseas coverage/plan is bar none the best available in the US for business and travel.

Here is a download link for a beta version of his upcoming Iron Rom. There is nothing about it, yet, on his site. I'm sure he would love feed back from more users, just remember that it's beta and not ready (or proven ready). It's so beta it's not even on his site, lol.

I believe his priority is Kernel (stable) > Rom (released) > CSC switcheroo for Note 8.

---

I've been waiting for his rom too, as I really like his Iron Kernel (Hands down best kernel perfomance:screen on time:battery ratio on Renovate Ice for my AT&T service reception/coverage/signal stability... Based on 3D Mark (extreme slingshot) and PC Mark (Battery test that runs continuously starting from >80% and drains down to to <20% battery life). Gained almost 2 more hours of screen on time (!).
[Samsung Galaxy Note 8 Questions and Answers] Ian the Great:
So I now have now a snapdragon /Qualcomm Note 8 purchased directly from T-Mobile.com and received yesterday.

I took the SIM out of my Clove UK N950F (slow LTE) and put it in the new T-mobile/Qualcomm device.

I have to say there is no comparison. The Qualcomm device gives far superior LTE speed immediately out of the box. Same SIM, same location, 2nd floor apartment building major city.

Its Not just better speed or a noticable increase in speed, but more like 1000% faster w/ a consistent connection at all times. Data speed is best of any device I've owned. The connection i get is full 5 bars even with closed door in bathroom. I do have an LTE repeater in this apartment, but even so I never had full signal in the bathroom.

Still hoping we find a fix for exynos. I really don't need two Note 8's but that is what I have now.

One thing I noticed about CSC that might be worth mentioning here. When comparing both phones systems side by side I see that the T-mobile device out of the box actually runs with an empty /omc. The /omc folder is there in system, but there is nothing inside. I don't think anything is hidden because everything else in system is visible.

I do have wifi calling and Volte all working no problems with T-mobile device. This is making me think that the /omc folder isn't really neccesary for anything. The stock T-mobile doesn't have it so why would N950F/FD need it? Is this correct or am I missing something here?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
You might need to enable viewing hidden files or something (not sure how you're looking there) but it is definitely in use in the firmware files. The N950U (all carriers and unlocked) have the standard group of CSCs with and including XAA. I pulled the files for my CSC patch from it.

Also - I'm curious of there's something wrong with the 950F software vs 950N. As soon as I got back on my stock SKC CSC my LTE speeds jumped back up to fine (I can get upwards of 100-130mbps downloads in my usual testing spot of the house). My T-Mobile Note 5 gets about 60-80mbps in the same area.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
I've always wondered this. Sure a F rom "works". but would be nice to have a "N" version with a "N" bootloader sans all the SKT and LGU+ crap ,
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
If one doesn't need T-Mobile wifi calling, I think you can do pretty much everything else with the base N firmware as is (VoLTE, RCS, HD and video calling can be had by manually enabling IMS), so you could just delete the OMC folder contents, as well as all the Korean carrier apps I imagine. That 'should' just load the default Samsung menus etc but I have never tried booting without any kind of CSC loaded.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
I tried to debloat the stock N rom, there are many APK's I have no idea what they were in relation to and messed it up to the point i got FC hell , is there a debloater script for the N versions ? or the S8 korean version i can modify?

So go to stock..

FULL BACKUP to microSD

boot to download mode

Smart switch emergency recovery back to latest N950N

Back to full stock.. (with wrong csc)

Reboot to download mode

flash TWRP

boot to recovery

in TWRP > advanced >terminal

type "su" hit [enter]

type echo "SKC" > /efs/imei/mps_code.dat

Format DATA (to remove encryption)

Install magisk

wipe data (for csc change to take effect)

reboot. should now be back to SKC stock.. with TWRP on stock kernel (patched by magisk)

reboot to TWRP

full backup of what you just did (so we can get back here without doing all that ^)

now restore just your data partition.

boom back to stock everything, with all your data as you remember it, 95% chance nothing breaks by adding in your current data to stock system.
