[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Welcome back! I hope things are looking up for you.

As far as this goes, I got it to work on stock N firmware finally. Basically the thing holding it back was that Korean TV system, tDMB. Somehow it was preventing the VPN connection for wifi calling from working. Soon as I deleted all of its apps/binaries Wifi Calling started working perfectly.

Current zip works on stock N and F, several F based ROMs but a few people on 2 ROMs are getting FC issues flashing over their existing setup, i think because of needing to clear app data for the couple of F-variant-only apps that i baked in to add support for our N devices.

If i get some time this weekend I'm going to see if i can have the script delete app data for those so it works for everyone, and also see if I can get the 256QAM and Carrier Aggregation CSC settings to load (they are included now but the file doesn't seem to be taking effect).
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Does this also resolve the issue some people had of wifi calls connecting but the microphone not working at all?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
AFAIK yes, I haven't had any reports of that happening, and mine has been working flawlessly as well. Rebooted probably 5-6 times, toggled wifi on and off dozens of times, toggled wifi calling on and off dozens of times.

The only thing that bothers me is that I don't know 'why' the DMB thing prevents EPDG from doing it's thing. I guess it doesn't matter since that only works in Korea on a Korean carrier but it's just annoying not to understand the functional cause.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Oh no. What will I do without DMB support in America on T-Mobile?

But yeah, I get what you mean. That is really odd.

So it sounds like for now, I should be able to just flash the latest on top of what I have now and be fine? I am on a custom kernel so that last issue mentioned shouldn't be a problem.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Yep, 2 people running Light ROM said they got FC from EPDG and IMS Service but didn't confirm if it was on top of a running system or fresh flash, 3 other people on custom ROMs said it works perfectly and 3 or 4 (counting me) said it works perfectly dirty flashing on top of stock N firmware, with the custom F-based kernel.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
on a side note, looks like all 3 carriers have January's firmware update out, SKT N950NKSU3BRA1 is up on Sammobile, but I'm not sure what's the point of updating the firmware every month? just security patches?

It's still 7.1.1 so I kind of feel like maybe just waiting until Oreo is out. Phone is working flawlessly at the moment.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Agreed I was going to update but then figured February is around the corner anyway and another update will.be up
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
I've flashed the latest zip back when I asked last time, but I haven't had a single chance to test it out yet on account of working 12+ hour night shifts every day for the last 2 and a half weeks now. :(

On a side note, I thought I might run something past you. My calendar app is rather weird, and I think it might have something to do with being a Korean phone, but not entirely (as you'll soon see). It's a bit off topic to the main post, but could be related to some of the csc/localization issues we were discussing before.

I'm mainly having two problems: 1) dates appear to be highlighted red based on the lunar calendar. The lunar date also shows up under the standard date whenever I have a date selected. This issue I can see being related to the phone's Korean origin. 2) there is a calendar enabled by default that I can only hide, but not disable (it has the same status as the "my tasks" or "contacts' birthdays" calendars) that appears to be Vietnamese in origin. It reads <see below> I can't imagine why I have it at all.

I'm wondering if at least the first issue has anything to do with the Calendar_EnableLocalHolidayDisplay value being set to "KOREA" in the csc, but like I said, I'm at a loss as to why I have the second issue.

Have you had any similar issues, or any ideas on how to fix this?

Note: Special characters in Vietnamese were screwing with my post and cutting it off right at the second accented character. Without accents, it reads "Cac ngay le cua Viet Nam".

UPDATE

changed "KOREA" to "USA" on a whim and that got rid of the lunar highlighting, though I don't think that's the proper value for US phones. Any idea what the value is supposed to be? Still stuck with the Vietnamese calendar...

MOAR UPDATE

I learned some more and thought I'd share in case there's any other interested parties. There's a line in our CSC that reads <CscFeature_Calendar_SetColorOfDays>XXXXXXX</CscFeature_Calendar_SetColorOfDays>. Anyone who wants weekends colored red (as is default in some regions) can change the value to XXXXXRR. Each character represents a day of the week starting from Monday. You can also use B to color a day blue.

[MENTION=4375750]Kalm_Traveler[/MENTION]

Ever since I moved to Hawaii from Phoenix my phone decided to go berserk once in a while loses all signal and gets stuck on band 26.. only a quick airplane mode toggle fixes this..

Any idea? I'm on December firmware base weta rom with ur latest zip.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
hmm I wonder if something in that ROM is doing it?

I have only used stock N950N base, and that September release of NEMESIS ROM, and never had the phone try to use a non-TMO band. Can you try resetting NV items in the service* mode?
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Ah I'll try the reset NV..

And I hope it's not the rom

Will report back
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
yeah let me know. I kind of wanted to try my hand at a full ROM once the T-Mobile patch works on everything - just debloated, de-knox, remove everything Samsung/Google that can be separately downloaded from the Play Store if desired.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
NV reset worked at the location i was in , not sure if it'll do it again tho
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Getting lots of people saying I sound really bad/muffled on the phone since flashing this. Not sure if related to this flash since I didn't call too often beforehand. Anyone else?
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
can't say the same over here...
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Crystal clear on VoLTE and Wifi Calling here. I've been fiddling with the modem service mode this week though and noticed it isn't auto connecting VoLTE and RCS when i leave wifi range, not sure what I did there.

Voice call quality has been fantastic though. There's nothing in this zip that has anything to do with the sound, microphone, etc.
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
Me neither, no issues with sound quality but I do experience dropped calls randomly & people not receiving my texts sometimes. I've since disabled SMS over IP & it seems to have made a difference.

I get random dropped calls when I'm on the move. When that happens I'll toggle VoLTE off. When I'm stationary VoLTE works perfectly fine. Didn't think I would still have issues in my area after all these years.

This is similar to when VoLTE was enabled in my area with the Note 5 but it was much worse then. Most calls dropped & experienced sound quality that was so bad I couldn't make out what the other party was saying, sounded like underwater. With my Note 5 I left VoLTE off all the time.

With that said, maybe try leaving VoLTE off for a week or two & see if it makes a difference.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Did a couple echo tests with VoLTE on and off, and that definitely seems to be the problem. Every call I made on VoLTE sounded compressed and had little bits of audio drop out here and there. This is area specific right? Every call I've made so far has been from the same geographical location.
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
Yep, I'm pretty sure it must be area specific as well as carrier network. I wasn't too surprised when I had issues with VoLTE & my Note 5 when it rolled out. But after years later I would have thought it would have improved. Well it has but it's not 100% reliable for me in my area. But if I'm closer to downtown I can't say that I remember having issues with VoLTE

They say calls are supposed to switch from VoLTE to HSPA+ when LTE drops but I've never actually seen mine do that on a call in my area. Usually it just drops the call for me.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Probably yes. I haven't had any of that at all in the areas where I've tested VoLTE or wifi calls.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
in case you were wondering, apparently in my fiddling/resetting the settings in the modem service mode, Data Retry was set to Disabled, which when I Enabled it fixed my lack of VoLTE + RCS , I am not sure why that gets disabled by default...
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Had to make a few calls today, from a different area this time. Got constant complaints about my voice quality until I turned VoLTE off. I wonder when I'll find an area where this works properly...

Where's this setting?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
modem service mode

ETC -> Common-> Test Equipment Setting -> Data Retry (when I reset NVSettings it is set to Disabled)
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Yep mine was disabled too. Do you know anything about this setting? There was some confusion as to whether the first option indicated the current state or the effect of selecting the option ("enable/disable this now" vs. "this is currently enabled/disabled").
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
Mine is set to disabled too. But I can confirm that my VoLTE works, RCS I don't know, I don't know how to test if RCS is working but it is enabled in IMS.

Yep, I too asked about that. Changing the setting doesn't seem to do anything. Set either way mine still says unsupported is the service menu but I'm wondering if I have actually be in an area where it is supported for it to report that it is. I know in my area it isn't supported yet.

Siimply adding the CP.xml to enable doesn't change the setting, that would be a good way to find out for sure if the CP.xml did work.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Pretty certain I've seen it not say unsupported in some areas though so…
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
Nice, thanks for confirming.

[MENTION=4375750]Kalm_Traveler[/MENTION]

So i broke down and upgraded to bra2 base BL and Modem and installed BRA8 Ironman rom, rom is amazingly quick , but i am having some funky issues again when using ur zip.

Does the CSC being on a older "base" pose an issue?

MMS isn't totally there and not sure where to start
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
Here's my experience, whenever I tried the later zips on RA2 or RA8 rom, I would get force closes. I have always been using one of KT's older zips, 3a to be exact. That one has always worked for me from day one on every ROM I've tried no matter what base. Worked fine for me on Weta RA2 & RA8 roms. I'm now running Weta QKG with RA2 bootloader & modem, everything works perfectly fine with no errors.

Only think I did like about the zip & not sure if KTs newer zips do it but I get the VoLTE icon whenever using the zip with pretty much most custom kernels. It drives me nuts. On stock kernel it doesn't appear & not sure why the kernel affects. I've tried other CSC mods & don't get it either. But I like KT's 3a zip so that's what I always use. But that's ok, I finally figured it out today.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
I'm using 9m1 which works well for me. I'm gonna hop on weta BRA2 ROM from Ironman and see if it gets better . Will report back
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Finally home for the first time in forever. Gave me a chance to test out wifi calling on my speedy gigabit network. Sounds perfect as far as I can tell, but the only number I had to dial was my google voice number on my computer. Lte sucks here in the basement so I'll have to test that outside when I'm not feeling lazy.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
so i swapped over to WETA BRA2 rom and all seems to be fine with latest zip. Weird how i got that behavior on Ironman and BRA8... oh well
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
Nice! :good:
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
what exactly are you experiencing? I haven't had time to work more on this for a month or so, but I'm also still on stock December N950N.

the actual CSC version shouldn't affect anything at all, but it's possible that the apps/libraries might not be playing nice if they are actually different in the newer firmware versions.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Signal drops, MMS\SMS failure when i have -97 db on band 4 , and other weirdness, but it's fine now on WETA... so it must be something in relation to BRA8 base that ironman uses?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Possibly yeah, i know a few people on Ironman ROM reported problems with the zip.

Next month when my spring break week comes I will see if I can't resolve them and put up an updated zip using the latest firmware versions. Normally I have some spare time on weekends during school but for some reason these 12 credits on top of a full time day job are kicking my butt.
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
KT, just curious, do omc.info, cscfeature.xml, other.xml, etc need to have 0644 for permissions? I just notice mine were not but they still seem to load/work fine. It's cause I made edits to some of the lines in a couple of files that I wanted then threw them back in the zip. That way everytime I play around with a new rom & reflash your zip & I don't have make the edits again. I can easily just use Root Explorer & change the permissions back to 0644 but it would be nice if I didn't have to.

I believe there's a line that could be added to the update-binary but I don't know what I'm doing exactly. I tried using the set_perm code but it fails with an error in TWRP.

This is what I tried entering (found in a tutorial but I assume it's the wrong "language"?):

set_perm(0, 0, 0644, "/system/omc/TMB/others.xml");

Thanks
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Is it possible that all this messing around with csc stuff could have broken Bixby? There's a few recorded cases around the internet of people who have phones (quite a lot were verified as imports) where Bixby will recognize everything you say but then respond with some version of "ok I cancelled it". Mine did that for a while but recently changed to saying some version of "it appears we can't do that in the context". I was playing around with some hidden debug menus when I found this log where it looks like it's trying to look up a rule set based on device info, including the sales code, model number, number of SIM cards, etc. I'm guessing Samsung's system doesn't have an entry for our modified configuration.

You can easily test yourself by asking Bixby to turn wifi on and off.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
You can also check the logs yourself by using any activity launcher to open com.samsung.android.bixby.settings.HistoryActivity

I'm interested to see what others have here...
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Doesn't have to but most files should be 644 in the system partition.

The only thing I tested was turning the camera shutter sound off because it kept coming on even though i toggled it off in camera settings. Bixby did it and it hasn't turned on again since.

Also the only Bixby thing i changed was making it use the American search sites since you didn't like getting Korean language results ?
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Yes but look at the screenshot. Not saying Bixby related things were directly changed. It looks like Bixby is sending device info to a server to determine what actions to take when a command is issued and the server isn't finding a match for this device configuration. Every action in the log returns the same error:

nruleSetVersion : [{"errMsg":"Can't find appropriate version info","queryInfo":"http:\\int.lbpp.dcog.rel2.ec2-us-east-1.n66.cloudpi.net\v0.1\search\ruleversionset?&appName=Settings&versionCode=25&salesCode=TMB&country=US&model=SM-N950N&numOfSims=1&binaryVersion=N950NKOU1AQHD&actorVersionCode=0&osVersionCode=25&simSlotCount="}]
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
If anyone here is willing, if you have flashed the tmobile zip but still have a working Bixby (ask it to turn wifi on/off to test), can you confirm the version numbers of your Bixby apps (voice/service/home/etc), as well as open up HistoryActivity under Bixby Voice using an activity launcher like Shortcut Master (Nova launcher also has built in functionality to launch activities) and screenshot the logs?

Trying to see if anything is different for people with working Bixbys.

If you want more information about the issue, check this link: https://us.community.samsung.com/t5...byQandA/highlight/false/page/1/thread-id/2818

Thanks
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
With some help from a user on the Samsung forums, I have finally debugged my Bixby issue. The problem was that changing the sales code and country of this device via this zip resulted in a configuration that does not technically exist (in Samsung's eyes), so Bixby's server did not know what to return.

Long story short, I had to change one line and add another to my build.prop in order to get Bixby working correctly. Whenever you issue a command to Bixby, it checks what it should do with a server, which returns different results back to Bixby based on the device configuration. The configuration details sent to the server include the sales code, country, model #, number of sims, binary version (though this seems to not matter), actor version code (not sure what this is), os version code (API #), and sim slot count (not number of sims). The problem appears to be that I was 1) missing the property ro.multisim.simslotcount (which I added and set to 1), and 2) the ro.product.model property was set to SM-N950N (which is an issue because no phone with the sales code TMB and country US should have the model number N950N). I changed ro.product.model to SM-N950U.

After doing the above, my Bixby appears to be working again!
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
any update? Another day of horrible signal and bouncing back and forth from band 2 to 4 100 times a minute.

Might just roll back to previous base since nothing seems to work right on newest base.
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
As in the TMO zip not working with Oreo?
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
No it's working but not as well as prior.

I'm on a rom build BRB2 ON WETA
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
Ah I see, I thought you meant Oreo & was curious if this still works on Oreo. I'm not ready to update to Oreo yet, waiting for the all the bugs to be confirmed fixed.

I'm on Weta BRB5/BRB2 also & have no issues. But I have always been using version 3a of the zip & I have an F. Hope you get it figured out.

Looks like official firmware for oreo dropped for our N models today///
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Have you done a read/write test by any chance? I wonder if it's somehow an I/O issue and not a connectivity issue? I realize this doesn't actually fix anything but just trying to pinpoint the issue.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
hmm you mean read/write of the internal storage? I have not, but wouldn't that be back to normal if Odin'd back to stock?
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Well, you'd think. I honestly have no idea what's going on. I'm just defaulting to "find out as much as possible and rule out as much as possible". But if for some reason (either by hardware or software) your I/O was affected, then you wouldn't have to waste time looking at LTE related things at least :P
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Good point, internal memory benchmark results are 585.05 MB/s read, and 254.67 MB/s write.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Well that rules out that. lol

---------- Post added at 14:32 ---------- Previous post was at 13:50 ----------

Well I'm just about to get my tmobile sim card from work :D I'll be able to test some of this stuff out then. I'm staying away from flashing any firmware other than stock N-variant though.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
good luck! With the handful of us that are having the mobile network issues, I am starting to think that it is a physical problem that just happened to surface after a few days of use rather than a software-related thing.

Here at work today I checked LTE strength and ran a speed test with current modifications, and then restored the stock EFS, and did a full factory wipe/reset with Odin, redoing the partitions and flashing the Userdata img before booting up.

Signal strength is identical, and data speeds are within the same level of terrible, even though the signal bars are full or mostly full (of course that means nothing since dBm is the real metric) . Really heavily leaning to a loose antenna wire now, but I'm curious to see what results others are seeing. Hopefully I don't have to open this thing up but on a $1300 device with no real warranty I see no better choice.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
well since i restored the EFS and did a full factory Odin reflash I figured it would be a good time to pull /system/ and do another compare against a 950F.

Made yet another new patch from scratch, triple checking the compare utility to make sure i was copying over everything that was absent on the N and.... no dice. Still no wifi calling - just sits on Enabling. I really don't know how/why it worked for me that one night and hasn't since. Though with a fresh ROM and this patch I'm not getting errors in the Logcat, so I guess that's nice.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
so my speedtests have been interesting (full stock KT). When the phone registers as being on "LTE+" my download speeds are 10-60mbps and upload speeds are usually around 15-30mbps depending on the signal strength and area. When it registers as being on "LTE" ususally dl and ul are both miserable or at most 10mbps, but one time I had like 1mbps dl and 25mbps upload.

Considering how good my lte+ speeds are, I"m afraid to flash anything onto this phone right now.

I also have next to no service in my apartment so getting wifi calling working is also a pretty major priority for me.
