[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
If you are getting those speeds with poor service I'm sure you'll be fine. I'm pretty convinced at this point that the suddenly awful reception is a hardware or assembly issue, and will be checking the guts of my phone soon (I have an i-fixit tool kit and dangerously high confidence).

As for wifi calling, I think the 950F ROM and my original patch are safe but I want to find the real difference between the two that is preventing a nice clean add-on/swap pack for the N variant. I looked a little more at the logcat last night and it looked like the epdg service couldn't get the hand off from LTE to wifi to happen for some reason but I don't entirely know what I'm looking at yet.

Also I decompiled all the apk's that are missing from the N but present on the F and U variants and skimmed through their android.manifest files for clues about what they interact with. There are a handful of libraries in system/etc and the dialer, settings, telephony and IMS apps mentioned so perhaps differences in those are the cause of epdg not being able to switch to wifi.

The key here is that once I figure out what all is necessary, I can keep the patch updated as new firmware is released for all variants.
[Samsung Galaxy Note 8 Questions and Answers] mardukeme:
Lte+ represents carrier aggregation, LTE represent just being on one band.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
See the funny thing is if I flash a 950F ROM like that Renovate one, even my original patch works just fine. (I was applying it after installing the ROM, before booting up). The situation now is that I can get the menu option to be there in Settings and the dialer but it is stuck on Enabling, and as far as I'm understanding the logcat messages, it looks like the Epdg service can't switch the phone from radio to iwlan interfaces but I am not seeing exactly why that is.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
also on a kind of pointless but amusing note, I was getting frustrated and decided to make a zip with every file that was different or only on the F variant and flash that (minus build prop and libsec-ril.so in /lib and /lib64) and what do you know, Wifi Calling works. This of course only makes me this much more convinced that the answer is only a few more files away, as I'm positive most of the apps, libraries, etc have absolutely nothing to do with wifi calling.

Sadly, this zip with all the differences is about 750mb which is much much more than I'm comfortable dealing with. I'm going to play around with adding 1-2 of the definitely-related items at a time until I can narrow down the culprit/s
[Samsung Galaxy Note 8 Questions and Answers] Kamikaze_Ice:
And that's why I wanted to mention my experience, it was completely different. I never had the options in the menus actually show up outside of #*#*4636*#*# menu and those are just visual only. I can only get that dialer menu working by flashing these CSC files (full or trimmed CSC selection, or your minimal pack). Also, I don't get those options on my HTC One (M8) or even using that dialer with same sim card :eek:

I did notice the Note 8 Dialer changed to include video calling and all related features also in the notification/quick settings area. And I was able to finish setting up wifi calling (got notification message from at&t confirming this).

I like puzzles but this feels almost as bad as the old thisisnotporn.com site (links to an archived version at thisisnotapuzzle.com).

Also noticed something else interesting. There must be something else this crap as I tried to keep korean CSC this time and noticed in original bootloader, after full flashes with PIT file, that a Multi-CSC is switching to AT&T.

It seems to say this regardless of CSC I flash now, although the CSC appears to be correct once booted. There must be some stray file that I can't seem to flash again outside of the PIT partitions and I have no clue where to look.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Did you look at the EFS partition? In the imei folder there are 2 dat files that contain only your 3 letter CSC
[Samsung Galaxy Note 8 Questions and Answers] Kamikaze_Ice:
I thought they were being wiped with the PIT file repartitioning everything when flashed with Odin.

I miss having total access to the filesystem and partitions on my computer via USB (I always forget to check via ADB).
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Pretty sure I have it this time - need some testers to confirm my success is repeatable with the following steps:

from full stock, enable developer options, OEM unlock and usb debugging

Flash TWRP with Odin, immediately boot into TWRP recovery mode and set it up (format /data/

in TWRP flash dm verity fix, Notorious kernel (might be optional), root (I used SuperSU out of familiarity), then flash my N950N T-Mobile zip

Reboot, allow phone to fully boot into OS, get fully into the OS (skip everything, no need to add accounts yet)

Reboot into TWRP recovery, do factory reset wipe, then flash my T-Mobile zip again, and root since you just lost it

Reboot system. This time you can set up your accounts

I just did this right now and have the Wifi-Calling icon now for about an hour, but i want some other people to duplicate my steps and see if this finally does the trick. I think the issue I was having is that we need to add all the files, let the phone finish booting up fully to set some setting that doesn't get erased with a 'factory reset' wipe, THEN reapply the patch and boot up again.

dm verity/encryption patch from the TWRP thread

Keep in mind this does not delete any bloat - the only thing it deletes is the stock /system/omc/ folder, it adds most of the files that the 950F has that our variant lacks, as well as the CSC, T-Mobile wifi calling + VoLTE stuff and a handful of other files from a 950U T-Mobile variant.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
Does this at least replace some of the bloat with US regional stuff rather than korea like we talked about before? This shouldn't trigger the LTE issues right?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Once someone else can confirm that I don't just keep getting weird flukes where it works for one night, I will have it delete all the Korean apps since they are useless to 99% of us (I speak Korean and try to make it over there once a year for vacation and they are still useless to me!) It does not replace bloat with more bloat - I think all the T-Mobile apps are downloadable from the Google Play Store if you wanted to have them.

For now I was just in a hurry to get it working from a clean slate.... sorry :o

I do not think that it has any effect on the LTE - mine as I mentioned seems to be not quite as bad on a hot day, and useless on a cold day. i still need to pull the back off and check for a loose wire inside (very convinced at this point that this is at least the issue with MY device... and if one had an antenna wire come loose, it's a safe bet that some others will too). I will check this weekend and report back if I find/fix anything while in there.
[Samsung Galaxy Note 8 Questions and Answers] jooniloh:
I mean hell I am korean and this is all useless to me. I hate that bixby cross references everything with a bunch of korean shopping sites. I hate all the system weather components get their data from some korean site that makes bixby tell me it's not raining as I'm standing out in the rain. Also I noticed the netflix app is missing from the play store? I was thinking that might have to do with the regional stuff as well. I'd just be glad if all that could be purged and replaced with their US equivalents.

I'll test your patch out right now and let you know what I find if you're gonna be around for a while.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
ooh thanks! I'll grab it and see if I can update the patch accordingly.

It also seemed like an easy fix for the F variant folks who had issues with epdg after flashing, I could just bake in a choice between N and F so they don't get files that are already on their system...
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
has anyone tried flashing CRC1 via odin on their N model? I can't get past the BL flash..

Update: looks like it won't work on Odin3_v3.12.7 . someone can correct me if i'm wrong or if there's ab etter version
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
Try v3.13.1
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
so i used the odin u perscribed, flashed everthing properly, loaded twrp oreo that's floating around, flashed oreo lightrom and got bootloop eternity. rolling back to nougat for now
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
Did you flash Oreo based kernel? With certain Nougat kernels it will boot loop. And without Oreo based kernel there will be random odd issues in the rom.

I too went back to Nougat. I did not want to try Oreo until TWRP officially got fixed as well as other things fully updated. But I decided to try using since there's at least a TWRP patch available. I knew Oreo was not much different & there are too many incompatibilities with the stuff I use so back to N until stuff gets updated. But as I posted in the other thread, TMO zip still works fine (the version I use anyway).
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
So I'm having a huge problem with signal..

I'm in downtown Honolulu on the 31st floor no physical obstruction. TMobile says band 2 dominates my street address and that's fine but dbm is all over the place one min it's -90 the next it's -120 , one min it's band 2 the next band 4 it's just erratic. All my sms fails even with WiFi calling but mms works. And even tho sms fails they still go through about a hundred times to the recipient even tho I sent it once.

I dunno what to do at this point

Edit: Still on Nougat, using the last release of KT's zip.

It literally bounces back and forth between band 2 to band 4 at least 2 times a second.

Text msgs fail but they go through about 10-30 times a piece, i've had friends call me angry that I am bombing their phones with sms and they can't stop it.

I dunno if this is t-mobile fault or if it's the phone itself :\
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Yes I flashed Notorious but it's fine i'm like u on nougat until oreo development catches up to a decent point
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
Did this start happening after upgrading to Oreo? Don't know what's going on in your case but just suspecting if it might be because of Oreo version baseband (modem)?

I didn't have any difference in connectivity when I tested Oreo but then again I choose not to update to Oreo bootloader & modem and I have a F.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
I can't conclusively say it's an issue post oreo as i've been slowly moving into this condo for the last 3-4 days.

My baseband is N950NKOU3BRA3 with KT's zip which changes CSC to N950UOYN2BQLA

---------- Post added at 07:21 AM ---------- Previous post was at 06:22 AM ----------

I'm in what's normally a good service area right now and it is randomly dropping LTE in favor for HSPA.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
for some context guys i had this issue in phoenix maybe twice since getting the Note 8 near launch... and both times signal dropped for no reason.

Anyway i'm about to jump back on Oreo because WETA has a TWRP data mount fix built into their kernel, ill test it out n report back.

KT any update regarding the new zip?
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
so i'm on oreo, using wetarom , it has a default XEF OMC and i'm able to send and receive sms without issue in my condo on the 31st floor.

So perhaps the culprit is wifi calling? i dunno, but i can tell you signal seems stable , and not jumping from band to band like crazy, i can't see anything in phone info in regards to finding out my band combo because the menu is not available in oreo?

Got anything in the works sir?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
Indeed - I am on-call this weekend though so I won't be able to test anything and don't want to subject someone to a zip that I have no idea about :) Next weekend for sure, gentlemen.

*EDIT*

In case anyone is interested, I'm using the 3CRC2 ROMs for putting this one together.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
where is that ROM found?? i'm confused
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
I get my stock ROMs from Sammobile.com
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
you could also use Samfirm too, it's much faster for downloads...
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
ooh I will have to check them out. I got both the SKC and TMB ROMs in about 3 minutes each from Sammobile but I always pay for a pass to save time...
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
oh you good to go then !
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
was delayed but I am working on the Oreo patch now. Got everything extracted and thanks to that new OMC decoder we have the exact N950U CSC features file to start with.

Oddly, Samsung started LZH compressing the individual .ext4 image files within the main .tar so I had to add a codec to 7zip to decompress the LZH files, but everything else seems to be as expected. If I don't have the Oreo patch out tonight it will be out tomorrow night for sure guys. So sorry for the delay!
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Can't wait!

I'm in Oakland for work for three weeks and signal has been poop!
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
[MENTION=4375750]Kalm_Traveler[/MENTION]

How's it coming along?
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
ah sorry, I got bronchitis and have been dying slowly since last weekend. I may need to 'work from home' this week so if that happens I should be able to finish the new patch.

Basically I have all the ROMs extracted, new CSC's decoded etc but I want to check the APK's to make sure I grab everything that is needed since the wifi calling apps are not the same anymore (as mentioned some of the previously-used apps are not present since Samsung finally created a unified wifi calling app).

it shouldn't take much time, this was just the worst possible time to get sick, end of semester etc...

I'm sorry and promise it will be up ASAP!
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
ouch don't even worry about it rigt now man you gotta get over bronchitis, that ish is no joke.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
thanks! yeah no kidding... and today is my birthday to top it all off. Last year I was in Seoul having a blast with a bunch of pretty girls, this year I'm dying at home alone trying to finish homework :eek:
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
You win some you lose some. Happy birthday!
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
any update? lol, i'm committing a unforgivable sin asking for ETA but figured i do so while i'm in the bay to test it out b4 i get back to hawaii
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
so sorry, I am working on it right now. ETA is tonight or tomorrow. I sort of built a new PC since the last update so just getting tools set up. If we're lucky I can just build a new version of the patch with the Oreo ROMs and it will work on the first attempt.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
I'm about to flash my phone to the newer Oreo N950N update, and test a first version of the TMO patch for Oreo.

Dumb question but I can just use Odin to push the Oreo firmware and won't lose anything installed/saved, right?

I made a full backup of everything but am hoping to just flash the Oreo firmware, immediately push TWRP, boot into TWRP and re-do the no-verity patch, Notorious kernel (Ironman has not updated his for Oreo yet), and SuperSu...
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
if you are flashing the full firmware you will lose everything as far as i know.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
I tried flashing the BL, AP, and CP files, then TWRP again, in TWRP did the no-verity patch, Notorious Oreo kernel, and SuperSu, then my first Oreo patch version

On bootup IMS Settings and System UI crashed indefinitely and the phone was mostly unresponsive.

I think flashing this way in Odin requires data wipe to work properly maybe but I am not ready to do that.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
yeah you're gonna have to, also, i have been going without the noverity patch.... can't remember where i saw it but we don't need it anymore?

Others can verify...
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
you using a custom kernel + root?

if that's the only issue, my Oreo patch may work.... going to try backing up Google Authenticator with Titanium Backup and do a fresh Oreo install in that case...
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Yeah, i did Odin oreo package, rebooted back into odin after it does it's thing, flash twrp , flask rom + kernel and i'm good 2 go.

BTW ironkernel is updated right now..

---------- Post added at 09:22 PM ---------- Previous post was at 08:34 PM ----------

also, if i may express i'm a bit disappointed with the slowdown of development and roms\kernels for our phone.. ,meanwhile my old Oneplus 3t forum is poppin with activity. why is it this way? is the note 8 just too perfect?
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
how did it go [MENTION=4375750]Kalm_Traveler[/MENTION]
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
didn't have time to re-flash my phone yet. I can upload the patch if you want to test it out as is though. It may work fine on a clean Oreo build - since I just dirty flashed Oreo on top of Nougat without wiping data, very likely that the FC's I was getting upon bootup were simply due to that.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
I think it's indicative of the competition in higher-end smartphones. I paid $1300 to have my N950N basically overnight-shipped from Korea, but here we are not even a year later and it's not top dog anymore. No regrets, I skip every other Note so I was already planning on using this one until at least the Note 10 is released but with fewer people owning the device, and many of the things people used to root for built into the mainstream firmware I think there's not the same level of dev interest that there used to be.
[Samsung Galaxy Note 8 Questions and Answers] masri1987:
Ill be a guinea pig.
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
You do still need it but you don't actually have to flash it if you are rooting. No verity is included in SuperSu & Magisk. So if you flash root after formatting data to remove encryption no need to flash no verity. But if you don't want to root for whatever reason, need to flash no verity after removing encryption before booting to system.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
haha ok give this a try in that case - minding that when I dirty flashed (with Odin) on top of Nougat that I got perma-FC's as soon as it finished 'updating apps' on bootup:

https://mega.nz/#!ViZ0BBJA!cZFCWTp9U1WPcJRYaV7iRkW2nNDp9h-RQAV6Y2Th16M
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
[MENTION=4375750]Kalm_Traveler[/MENTION], if you are still having trouble with moving to Oreo, try this.

While on Nougat with TWRP, first update TWRP to newer Oreo compatible TWRP. Older TWRP will not be able to mount data so you can't flash anything in TWRP or make nandroids. Flash Oreo TWRP image in TWRP by kairi_zeroblade from here. Tkkg1994 recently just updated his TWRP build for Oreo also that fixes the data mount issue but I haven't tried it yet.

Then flash latest Weta rom. Since you have N, obviously don't flash Weta BL+modem as they are for F (seperate zip anyway). If you are on latests Nougat BL+modem Oreo will work without updating to Oreo BL+modem. You can update them later if you decide to stay on Oreo.

In Weta installer, choose no CSC option. After Weta installs then flash your CSC. If you have issues, try installing Weta with XEF CSC, then boot to system & let everything install, then boot back to TWRP & install your CSC zip. Sometimes it doesn't like CSC flashed flashed right after new rom install that hasn't booted at least once. Also try using official Xceed kernel if you get weird FCs in Settings, IMO that's currently the best kernel for Oreo.

If that works, while testing your CSC, please check if MMS sends without failure & actually gets delivered, if MMS works with Wifi calling enabled, & if send very long SMS actually gets delivered. These are all issue with various TMB CSC for Oreo. I was able to get them all working.

Looking forward to your zip even though I'm back on Nougat, not a fan of 8.0 Oreo. Hopefully we might eventually get 8.1 & it's better, then I will go back to Oreo.
[Samsung Galaxy Note 8 Questions and Answers] Kalm_Traveler:
oh I didn't have any issues with TWRP... I am/was on basically stock Nougat, and Odin'd stock Oreo on top of it, re-Odin'd TWRP, TWRP'd a kernel, no verity, supersu, and an initial attempt of my T-Mobile patch built from N950F and N950U stock deodexed firmware.

When it booted up I got perma FC's from IMS Settings and I think System UI, and the phone became basically unresponsive so I TWRP'd back to Nougat (took a full backup just before trying Oreo). I am still on the Oreo modem and BL. everything is working fine like this but i want to get moved over to stock Oreo.

I can say that my MMS over WiFi works just fine on Nougat with the 'last' version of my T-Mo CSC patch for it.

Don't really want to throw another ROM into the mix by using Weta since I have no idea what it is built from, and my whole motivation for doing this was to make T-Mobile Wifi-Calling work on an N-variant device's stock ROM since everyone else's patches only got it to work on F variants.
[Samsung Galaxy Note 8 Questions and Answers] shouren04:
I understand not wanting to use a custom rom for purity reasons. I haven't ran into FC issues when dirty flashing Oreo over Nougat except for Settings FC with stock kernel.

You probably didn't run into the unmountable data issue since you flashed everything at once and with custom kernel. Some kernels have the data mount issue patched in. But it would be a good idea to update to the updated TWRP anyway so you don't ever run into that issue. If you do you won't be able to restore a backup but that can easily be fixed.

so after 16 hrs i re-odin'd my phone from scratch. I'm on default XEF csc from weta right now, gonna stay on it until we can figure out why there's a ton of FC's when i install the zip
