[Samsung Galaxy Note 9 Questions & Answers] adawn217:
First of all, I want to say thanks for your thorough guide. Having never done any kind of flash or root to any of my phones before (because I was more than happy with them stock, lol), I was nervous, but your steps were great. It took a few tries and some frustration on my part (kept getting "can't open the serial COM port" even though I was using the factory cable), but once I figured out the issue (since it was literally the first time I'd ever hooked the new Note to my system and installed the USB drivers, a reboot of my laptop seemed to fix it) it was smooth sailing.

When it was no longer hanging, I did everything, got the green PASS, phone restarted itself, and . . . I still had Pie.

I'm now figuring I did one of two things wrong:

1. Most likely:

The Firmware I downloaded from SamMobile was the wrong one. I was finally in a port where I could get some fast Google Wifi as ship internet is waaaaay too spotty and was going to take four days (maxes out at about 70 kb sec but averages about 40-50). I didn't download the 2019-01-13 one but this one as it matched the baseband/build numbers in my phone

( 2019-04-24 9 N960U1UES1CSD1 N960U1OYM1CSD1)

So with that said, I'm SUPPOSED to use (2019-01-13 8.1.0 N960U1UEU1ARL1 N960U1OYM1ARL1), even though that doesn't match my build number?

2. Less likely:

As IT_Architect is quoted above, I didn't do a factory reset before I started. When the phone restarted, it did indeed connect to wifi and start doing the updates.

I'm so disgusted with my idiocy right now! I just knew with this down time I was finally gonna start being able to use my new phone, but of COURSE I had to screw it up, lol. Now I've gotta wait 'til Saturday when we're back in the US.

You're welcome IT_Architect! I'm glad it was helpful. That's a good suggestion... I'll edit the original post and reference this post as well.
[Samsung Galaxy Note 9 Questions & Answers] JohnNadeau:
You're welcome! This stuff is surely frustrating... don't be so hard on yourself LOL ! Betting #1 above is the likely issue, and yes, that's the one you should download. I'm going to edit the original post to include a reference to IT_Architect's suggestion. Please let us know how it goes when you try again.
[Samsung Galaxy Note 9 Questions & Answers] adawn217:
My phone actually is US unlocked, and my service is T-Mobile. I've not inserted the sim yet because I haven't set up the Note 9 at all yet. I'm still using the A6 I had purchased as an in-between phone because i was SURE i was doing to buy the Note 10 once my Note 4 died. But the specs on the 10 and the great Amazon Prime Day price on the 9 made up my mind.

So that said, the baseband/build version is PPR1.180610.011.N960UES1CSD1, so I think I'm ok in the U1 regard, yes? I am concerned about the WiFi calling thing, but it sounds like, since my carrier is T-mo, i might have that issue anyway and a phone call will resolve it?

WiFi calling is the other reason i need to switch back to Oreo as well, as it had "WiFi only" as a calling option. Pie's "WiFi preferred" and "Cellular preferred" have resulted in way too many accidental charges because the phone switches on its own from WiFi to Cellular at Sea, AT&T's cruise line service at $5.99/minute and .50/text. I will say TMobile has been great and refunded me the call charges ($30 last month). I just eat the text charges, last month was $5 worth.
[Samsung Galaxy Note 9 Questions & Answers] IT_Architect:
10 would have also cemented you to Pie and very poor call recording.

Yes, that shows boot loader (BL), 5th character from the right, as version 1.

It might be unlocked from your carrier, and the phone from the US, but from the number it does not present itself as a US UNLOCKED phone. While physically the same hardware, they are different model numbers. US UNLOCKED will read N960U1ES* while carrier-specific phones will read N960UES*. If you look at your Phone model it should read SM-N960U. When you finish flashing your phone to the U1 US UNLOCKED Oreo, it will read: N960U1EU1ARL1 and the model number of your phone will change to SM-N960U1. You need the patched ODIN to allow you to switch to the U1. The U1 does not include USERDATA (Carrier specific) firmware while the carrier versions do. When you are at SamMobile, you will want the U1 firmware, not the U firmware. Notice while you are there that the new versions of Pie are BL version 2(poison). No matter how things change there, but keep your eye on that 5th number from the right to save yourself weeping an nashing of teeth. Some people are automatically taking in Pie upgrades to BL version 2 without their knowledge of the ramifications of doing so. If you ever see an upgrade pop up that won't let you use your phone, don't upgrade because you have no idea what it is trying to do to you. Reflash to regain control of your destiny. CURRENTLY all of the carrier firmware (U) is on BL version 1, Pie included. That is not the case with the (U1) firmware.

You can learn a lot about your phone that Settings doesn't show in the Samsung-specific Phone Info *SAM* app.

That is precisely why I didn't ring your bell when I found a way around the Pie upgrade by using US UNLOCKED firmware. As I mentioned before, in the U1 firmware, oddly, for a phone that is marketed as US UNLOCKED, there are branded U1 versions. I flashed the Verizon branded U1 but the only change I could find is it showed Verizon logo on boot-up instead of Samsung, but there may be more, and T-Mobile's might be different. You might want to subscribe to Restore Call Recording to your Note 9 SM-N960U and SM-N960U1 where I am in a discussion with gruuvin, a fellow T-Mobile user of yours, about Wi-Fi calling on T-Mobile using U1 firmware, which is exactly what you need to know, and see what shakes out.
[Samsung Galaxy Note 9 Questions & Answers] adawn217:
My typo

My bad. It actually is N960U1UES1CSD1. It better had been cause Amazon, Samsung and I were about to have a conversation since I didn't buy it from a carrier, lol.
[Samsung Galaxy Note 9 Questions & Answers] IT_Architect:
That puts you on the 9.0 U1 build from 2019-04-01. Just don't say yes to any updates. Then your model in Settings/About Phone shows the Model number: SM-N960U1 also. When you boot up do you see the T-Mobile or Samsung logo?

When I logged into the U1 area of SamMobile just now I noticed a whole lot of the 8.1 software was missing from the archive that I saw there before. I have it on my hard drive now, but I don't know if it's just me and they are hiding it because I already downloaded it or if it has actually removed from their archive.

I have 960u t mobile unlocked can i upgrade to oreo ??
[Samsung Galaxy Note 9 Questions & Answers] IT_Architect:
Based on what you posted, yes. That is precisely the phone I started with.
[Samsung Galaxy Note 9 Questions & Answers] IT_Architect:
I just did a backup of my Note 9 using SmartSwitch and mentioned an update. That scares me. Have you experienced that?
[Samsung Galaxy Note 9 Questions & Answers] JohnNadeau:
It's been a while since I've used/updated SmartSwitch. That's certainly a cause for concern! Yikes, can you imagine going through all of this to restore Oreo and SmartSwitch installs PIE?

I wonder if SmartSwitch is referring to App updates?

Regardless, I'll make a note in the original steps.
[Samsung Galaxy Note 9 Questions & Answers] adawn217:
I did it!

Sorry I haven't been purchasing internet this week to update y'all with all the assistance and patience you've show me. I downgraded successfully!! Went through all of John's steps (including the ADB software update block using Minimal ADB I had already downloaded for a Fossil Watch issue) and IT's advice along the way, and everything is everything! The indicator for WiFi calling is back, so no more unexpected charges! I have also realized how much better Gboard is in Oreo! I swipe, and when it gets it wrong, the word I meant is usually in the suggestions no problem. It only takes one use of a word for it to learn it, so all my profanity came back after one session, lol! There are a couple ( Like LITERALLY only a couple) of things I miss from Pie (like the screen capture button from GoodLock on OneUI), but I can definitely learn to live without them.

But... However...

My call recording isn't working. I was always using the basic Call Recorder from Green Apple Studios. and four calls in, only one has recorded anything. The other four the mp3 file won't load or it's an empty file that sounds just like it did when my A6 updated to Pie. The one that did record, only got my end of the convo. Should I be worried, or is there a different app you would suggest?
[Samsung Galaxy Note 9 Questions & Answers] IT_Architect:
It will be working shortly. What you need is Automatic Call Recorder by Appliqato, BUT DO NOT download it from the play store. Go to apkpure.com, and down version 5.43.11 or the one just below it. Nothing newer that 5.43.11 will work exactly right. Then sideload it with the Samsung File Manager. You will have fabulous call recording. The default install is with the voice very low. Just run the volume rocker up while do a playback and it will remember it from then on. We've tested call recorders A LOT over the years and this IMHO is the one to beat. If it works well, I'll give you some more tips for it. I can't imagine you won't love it. We have the Pro versions and the only way we get away with that is we exported them from our old backups to APKs. However, the free one works just as well, but I believe it only keeps 200 and then rolls off the oldest. The Pro will do probably 1,000. Please let me know how it works for you.

Actually, you caught me refining steps and I'll probably have things nailed down this weekend and plan to work on it through the night. Then check here again. Restore Call Recording to your Note 9 SM-N960U and SM-N960U1 for details how to avoid the Play Store Policy Ransomware Virus.

I take it that's different than pressing the power and volume down button?

PS: I stopped by T-Mobile a few hours ago and popped out my Verizon SIM and popped in a T-Mobile SIM. Instantly I had VoWiFi. I will probably be trying T-Mobile. VoWiFi and that is a deal maker if you travel.
[Samsung Galaxy Note 9 Questions & Answers] JohnNadeau:
Great info!!! I'll reference it in the Original Post.

Thank you !
[Samsung Galaxy Note 9 Questions & Answers] JohnNadeau:
Glad it went well! Great feedback. Thanks!
[Samsung Galaxy Note 9 Questions & Answers] IT_Architect:
I worked on that works perfect for me now and PM'd you with so I wouldn't muddy up your thread, and you can pick out anything you might want to add. It lost all the formatting and pics in the PM of course, but you don't need that anyway. I'll adjust my thread to whatever you write for the areas that need to be a little different for call recording.

Thanks!

Doesn't work for me in my phone Tmobile sm n960u

Failed in odin

Baseband

N960USQS1CSE1

Build Date:

Thu May 2 10:35:06 KST 2019

I think i need to download 2018-12-01 firmware N960UOYN1ARL1

To work ??
[Samsung Galaxy Note 9 Questions & Answers] IT_Architect:
Your phone was built about the same time as mine. I am using the N960UOYN1ARL1 2018-12-01 firmware, but I flashed many different versions. It is the last U1 Oreo, and I've found no downsides to using that latest version.

1. You must have a high quality USB-C cable. If you have the cable that come with it, it will work. Ensure you can easily browse your phone from your computer. Mine is USB 3.0 capable, all conductors, and plugged into a USB 3.0 port, which have more power than USB 2.0 ports.

2. The battery charged to 85% or more. The phone will be warm when you are finished.

3. For the US UNLOCKED carrier-independent firmware, you must use the patched version of ODIN as specified.

4. The firmware must be for the correct model. E.G. it must be for the N960U*

If you have these, I can't imagine it wouldn't flash for you.
[Samsung Galaxy Note 9 Questions & Answers] hamzalp:
Thank you [emoji3590]

Another question please i have unlocked Tmobile

this firmware work for me or i need Different

Firmware
[Samsung Galaxy Note 9 Questions & Answers] IT_Architect:
I also started with a new T-Mobile Unlocked. I am using the normal US UNLOCKED firmware labeled XAA.

Backstory: I accidentally flashed the TMK which, which was errantly stated as the one I needed, and learned later was MetroPCS. However, the phone information after flashing showed XAA. Then I downloaded the XAA, which is the correct one, but when I compared the files using MD5 and SHA-512 and they were exactly the same. So then I downloaded the SPR, ATT, etc. They were all the same. I have no idea why they do this. The U carrier firmwares are different as expected, but there is no expectation for U1 firmware to be different because it is only sold only by non-carrier outlets where they have no idea which network the phone will be used on. The hardware is precisely the same between the U and U1, and U1 will always show XAA after you finish flashing. While perfecting backup, flash, and restore procedures, I flashed last with the XAA zip before quitting and threw away the others to save disk space and prevent confusion later. I documented my discoveries here: US Note 9 Carrier-Specific vs. US Unlocked Firmware Observations & Theories

EDIT: If you got this too late and downloaded the other one, don't worry about it. Rename the the zip to XAA and walla!
[Samsung Galaxy Note 9 Questions & Answers] IT_Architect:
BTW, how do like T-Mobile?
[Samsung Galaxy Note 9 Questions & Answers] adawn217:
That did it!

After installing the APK and calling home, EVERYTHING WORKS NOW!!! You and Jon are gentlemen AND scholars in my book. Now to try and sell this Galaxy A6 to another crew member!

Yeah. You know how that damn Nav bar takes up real estate on EVERY G-D screen, no matter where you go in Pie? It's an extra button you can add on to the bar in GoodLock for OneUI for one-hand screenshot. Very handy since the case I use makes the button presses kinda difficult and screen swiping sometimes catches the Edge Bar (that I keep forgetting to use, lol).

T-Mo is great for travel with their text/data included in almost any country you go to. The WiFi calling works great, and while some people complain about that constant indicator in Oreo, in that indicatorless update to Pie on my Galaxy A6, I racked up probably $60 in charges over the two months I suffered 'til getting the Note 9 set up since I didn't know the call had switched from WiFi to Cellular at Sea ($6/min), all of which T-Mo graciously refunded with NO pushback whatsoever. I usually ate the charges for the .50/texts since I used to forget that even before I had unlimited internet (which probably ended up being about $15 over the entire 10-month contract at sea), but this last time, she even gave me that when I didn't ask for it.

I have never, ever had a problem with T-Mobile and find their service AND their CUSTOMER service to go above and beyond since they don't have to check with their managers before they use their own common sense about things. Between my sister and me, our bill is a flat $90/month (since she rarely uses data, we get another $10 discount off the $100/mo contract price when she stays under 3GB). While I was out here using the ship internet, I even kept under 3GB for two months straight...'til I had to download the 4.4GB SamMobile file in Port Miami the other day, lol. I'll never forget when I left AT&T in 2012 and they tried to make me--who had been buying my own phones straight from the Nokia store in NYC and not on ANY contract in about eight years at that point--pay $85 to cancel my contract with them. Man, I was on the phone with them for an HOUR arguing before they finally removed that balance.
[Samsung Galaxy Note 9 Questions & Answers] IT_Architect:
Faboulous! That's what I was hoping to hear.

I wonder if I should map my Bixby button long press for that.

These are things that I need to know because my end game is Colombia and setting up an orphanage and will be bouncing around at first for sure.

I'm also looking at VOIP with CallHippo. For $15/mo. I get one line free in any country, additional lines for $6/mo., call recording and call logs kept and backed up forever, free inbound and 200 minutes outbound and $.01/minute after that. (Which would include call forwarding and any conference calling that you host.) I get SMS, but no MMS, but in a lot of countries people use Signal (Like WhatsApp except private) to do voice, video calling, and its builtin MMS-like chat is more powerful and easier to use than MMS, and totally private. If I swap change carriers/swap SIMs, nothing changes, I can ring multiple devices, and send and receive calls from anything you can install their SIP/VOIP client on, which means tablets, laptops, etc. This way there are no limitations that can ever again be placed on me by Android/Google, the Play Store, the phone manufacturer, or wireless provider. Whoever the wireless provider is that I choose becomes simply a wireless ISP who sees nothing but an Internet connection. If he doesn't have data-only plans, he is simply hosting a number that I may never use. 1 GB of data is good for 1200-2000 minutes of voice, so even a dog connection can support that. It's difficult to envision having wireless service available without also having data. With LTE, it's impossible. LTE cannot transfer voice anymore than IP can. The both require digitized voice sent in data packets. LTE requires VoLTE just like IP requires VOIP. What little I've played with CallHippo is it works VERY well.

Your T-Mobile feedback was very valuable to me during the transition. I must run the US UNLOCKED firmware to have the best international connectivity and retrain Oreo to have good call recording, but Verizon does not support VoWiFi.

FYI, Google Voice VOIP is free so you will never lose your number and has great long-distance rates. However, call recording is inbound-only, must be a US number backed by a real US number by someone somewhere, and since you are the product, it is not private. It also works very well.

Thanks!

Thank you SOOO much for this post! I'm on One UI 2 beta right now and gonna attempt to downgrade later this week. Btw for the patched Odin, which version do I need? There are 4 different files in the thread you linked
[Samsung Galaxy Note 9 Questions & Answers] JohnNadeau:
You're welcome!

When I wrote the original post, I downloaded and used Odin3_v3.13.1_3B_PatcheD.zip on Windows

Looks like [MENTION=4396505]realbbb[/MENTION] added a newer version on 12/12/2019: Odin3 v3.13.3_3B_PatcheD.zip.

I would be inclined to try the newer version first.

You mentioned your phone is on One UI 2 Beta currently. Double check the Bootloader Version. See the Original Post and the Preliminary Questions and corresponding link regarding the Bootloader version. If you're on Bootloader v1, all should be good. If you're on Bootloader v2, you might not be able to downgrade. Although it seems like someone mentioned there are some Oreo Bootloader v2's available for specific models.

Good luck and let us know how it goes!

U3 is the bootloader

---------- Post added at 10:49 PM ---------- Previous post was at 10:49 PM ----------

You can only downgrade to firmware that has U3 or S3 bootloader
[Samsung Galaxy Note 9 Questions & Answers] gamersekofy:
So I can't downgrade to Oreo then?
[Samsung Galaxy Note 9 Questions & Answers] butchieboy:
This what usually happens, people have no idea that upgrading the bootloader means your stuck on that firmware. Unless there is Oreo with U3 or S3 bootloader then no you cannot downgrade
[Samsung Galaxy Note 9 Questions & Answers] gamersekofy:
Darn I should've had more patience. Do you think I could go to a uBreakiFix store and get them to downgrade my phone?
[Samsung Galaxy Note 9 Questions & Answers] butchieboy:
Um I have never heard of anything like that. How are they able to downgrade your bootloader? Dont know where you get that info.
[Samsung Galaxy Note 9 Questions & Answers] BluePhnx:
I think by changing the motherboard out with a new one and asking them to install the oreo firmware instead of the PIE one on the new motherboard. Which most likely be pricey to do but it's an option though to try!

edited: I haven't done it myself or asked. Was giving an option to try that route if possible!
[Samsung Galaxy Note 9 Questions & Answers] butchieboy:
Well I have heard that mentioned years ago but didnt think people actually did it. Saw it talked about way back when Note3 was the it device and people wanted to go back to Jellybean after upgrading to kitkat, but again never knew any that did it. I stand corrected
[Samsung Galaxy Note 9 Questions & Answers] gamersekofy:
Well I thought that since they have a partnership with Samsung they might have access to special software that might be able to downgrade the bootloader and the OS
[Samsung Galaxy Note 9 Questions & Answers] BluePhnx:
Give the service center a call and see if they can.

Let us know if they can!
[Samsung Galaxy Note 9 Questions & Answers] gamersekofy:
I just called them and they said that they unfortunately can't downgrade because they don't have the tools :(
[Samsung Galaxy Note 9 Questions & Answers] BluePhnx:
Thanks for the info!

So the only option is to switch out the motherboard and hope that it came preinstalled with the very first firmware or at least Oreo.

Have a Happy New Year!
[Samsung Galaxy Note 9 Questions & Answers] gamersekofy:
That sounds complicated lol. I guess I'm stuck on One UI 2 now.

And Happy New Year to you too!

Hey quick question. What's the difference between U3 and S3? I'm on One UI 2 right now and you said that according to my build number I have a U3 bootloader. I found a couple of Pie versions with S3 in them (N960U1UES3CSJ1 and N960U1UES3CSK1). Can I downgrade to one of those firmwares?
[Samsung Galaxy Note 9 Questions & Answers] butchieboy:
As long as number matches your fine U=firmware upgrade S=security upgrade. Maybe read up a little bit so you know and understand what your doing. Knowing what bootloader your on is basic info.
[Samsung Galaxy Note 9 Questions & Answers] gamersekofy:
I see. So I should be able to downgrade to an S3 build from a U3 build, right?
