For those of you that use TMO or U1 firmware on an unlocked ATT phone on TMO network, do you get a <Subject: NoSubject> before other people's texts in group texts? I've tried flashing U and U1 firmware several times as well as factory reset without being able to get rid of the subject line. Anyone have any insight or suggestions?
[Samsung Galaxy S9  Questions & Answers] Littleibrat:
I was able to go from U1 to the att firmware. My question is why does samsung pass not work? I can see that the knox is not tripped and google play store is certified. Device status says official. Device is not rooted but Samsung pass thinks it is rooted. Why would this happen when all I did was install the carrier bundle?
[Samsung Galaxy S9  Questions & Answers] MFmvrdoc:
(Newbie) doing what jrockz3000 did would allow root to be possible?
[Samsung Galaxy S9  Questions & Answers] ajairola:
Unfortunately not. All North American S9s are not able to be rooted at this point.

Just got reman 9+ from amazon. Has g965u1ueu1arb6 firmware on it. is thatBL1? and its says att/att/xaa. so can i flash vzw u1 firmware to it? and does anyone know if i should leave it alone for a chance to root with BL1, would i have better chance? also how do i get into BL mode on these sammys? used to moto and nexus devices. TIA
[Samsung Galaxy S9  Questions & Answers] jcsww:
Check the model number first under Settings, About Phone. If it says, G965U1, then you are still on the U1 firmware. If it says G965U, then yes, you will need to factory reset and flash to the U1 first. Your device is currently on the v1 bootloader, which makes converting, if needed, very easy.

Thanks, I have a question, I am try to flash T-Mobile ROM on xifinity S9 that has android 8 on it. should I proceed with the same process. or get the latest T-Mobile ROM. Please help
[Samsung Galaxy S9  Questions & Answers] jcsww:
You need to factory wipe and flash to the U1 non-carrier specific firmware first after enabling USB Debugging in the Developer Options once you factory reset. Pop your T-Mobile SIM in and put the device into download mode. Make sure you find the U1 version that has the same or a newer bootloader than your device currently has. You can not flash a previous version of the bootloader. Do not use the file called, HOME_CSC when flashing any of the firmware unless you want the potential for issues. Once you flash the U1, skip through the setup, don't activate WiFi or sign in with your Google account and head straight to enable USB Debugging once again in Developer Options. Back into download mode and flash the TMB firmware, again making sure you don't flash the HOME_CSC (there is another CSC that does need to be flashed) and everything should be good.
[Samsung Galaxy S9  Questions & Answers] oscar786:
This T-Mobile ROM is taking forever to download, it’s been 18 hours and still downloading. I have Comcast blast and that downloads really fast , but this one is taking forever. Any suggestions please
[Samsung Galaxy S9  Questions & Answers] jcsww:
Most firmware download sites are really slow. SamFirm sometimes is a little better but it ultimately depends as on the day.

I have the at&t g960u. Got error using command prompt so I booted to 'download mode' manually. Followed all the steps but Odin showed FAILED. with error- can't open the serial (COM) port.
[Samsung Galaxy S9  Questions & Answers] jcsww:
Do you have USB Debugging enabled within Developer Options?
[Samsung Galaxy S9  Questions & Answers] anifowose:
Yes, USB debugging is enabled.
[Samsung Galaxy S9  Questions & Answers] jcsww:
Are you using the modded or patched ODIN? Have you tried a different USB port?

what would be the reason for doing all this stuff, I'm on a sprint galaxy s9
[Samsung Galaxy S9  Questions & Answers] oscar786:

[Samsung Galaxy S9  Questions & Answers] za33ck:
Other than call recording, and no bloatware, is there any other advantages for doing this, just trying to see if the risk is worth the reward kind of thing
[Samsung Galaxy S9  Questions & Answers] jcsww:
If you check Updato, SamFirm, or Samsung Science, you want the firmware usually tagged XAA. This one from Updato, although labeled USC, is actually the XAA with the v3 bootloader. Any firmware you flash after this point though will need to have the v3 bootloader or newer.
[Samsung Galaxy S9  Questions & Answers] oscar786:
So flashing this V3 bootlader will work. As per your advice and my understanding is I be chosin only BL, AP, CP, CSC not the userdata in U1 and Tmobile ROM. am I right? Thansk again
[Samsung Galaxy S9  Questions & Answers] jcsww:
There is no need to flash the userdata with any U1 unless there is some specific blat you want.
[Samsung Galaxy S9  Questions & Answers] oscar786:
Hi jcsww, I downloaded this and try flashing with moded odin, still same error, any help please
[Samsung Galaxy S9  Questions & Answers] jcsww:
Do you have USB Debugging enabled in Developer Options? Do you have the Samsung drivers installed for the device in download mode? Are you using the USB cable that came with your device? Are you using a USB port that doesn't share resources with other devices?
[Samsung Galaxy S9  Questions & Answers] oscar786:
odin is recognizing phone on com port, doesnt it mean its recognizing the device? or which drivers you want me to instal, thanks
[Samsung Galaxy S9  Questions & Answers] jcsww:
If ODIN is recognizing the device and displaying a port. Then it should have the driver it needs. Are you using the modded or patched ODIN?
[Samsung Galaxy S9  Questions & Answers] oscar786:
Yes I am, it loads BL and all others , then fails, I tried on windows 10 and windows 7 as well . No luck
[Samsung Galaxy S9  Questions & Answers] oscar786:
Hi jcsww, I am using moded ODIN, latest U1 (that you provided in previous post), Odin is recognizing the phone on com port. but still failing. Can you please recomment something else to successfully flash T-Mobile firmware on Xifinity mobile (unlocked) S9 . Thanks again
[Samsung Galaxy S9  Questions & Answers] jcsww:
Trying a different cable and or USB port is all I can think of. Shared ports tend to be an issue for flashing. There is also a setting in the Windows Power Management that allows Windows to disable devices connected over USB when it thinks they aren't needed. Disabling that might help. A high quality cable, like the one that comes with the device can also make a difference. Being able to charge and transmit data simultaneously makes sure the cable is up to the job.
[Samsung Galaxy S9  Questions & Answers] thedillybar:
Update:

I had to use a patched Odin 3.13.1 to get around the SHA256 error. See this post. (The Odin link earlier in the thread is broken)

After installing the U1 firmware from OP's follow-up post, I decided to stick with U1 rather than go to a T-mobile branded firmware. The firmware will still update, WiFi calling & Visual Voicemail work great.

If you really want the T-mobile branded firmware, you can get it from SamMobile. The link earlier in the thread is broken.

Cheers

I flashed one of the files with the version 3 bootloader, it was successful however I can no longer make calls or send messages. error is: not registered on network
[Samsung Galaxy S9  Questions & Answers] jcsww:
Let me guess. You flashed using the HOME_CSC? If so, relfash and use the other CSC. Never use the HOME_CSC when cross-flashing.
[Samsung Galaxy S9  Questions & Answers] anifowose:
yes, I flashed the HOME_CSC. I have reflashed with the normal CSC but error persists.
[Samsung Galaxy S9  Questions & Answers] jcsww:
Are you using the modded or patched ODIN? What did you flash from to (last 5 characters of the firmware). Did you cuange any options in ODIN? The options need to be left at their default.
[Samsung Galaxy S9  Questions & Answers] anifowose:
I used Modded Odin with default option. from: 3ARI6 to 3ARJ6, product code CSC

side note: I'm trying to move to unbranded firmware.
[Samsung Galaxy S9  Questions & Answers] jcsww:
Can you try a different download site for the firmware you are trying to flash? Flashing for any U to J1 is normally very straight forward.
[Samsung Galaxy S9  Questions & Answers] DirtyWhiteBoy707:
I don't know why someone would go through the trouble of making a story up like this. But im pretty sure back in root/custom rom 101 samsungs first law says You cant do any of that without first unlocking the bootloader. Like what was achieved with the verizon note 4. Now the att note 9 as far as i know hasnt had its bootloader cracked yet, and will possibly stay locked indefinitely.

Hey guys I'm a newbie I got a s9 from Samsung as a replacement & its locked to tmobile. Becuz the 1 I sent in was a tmobile phone. T mobile will not give me the unlock code for this new device becuz I dont have an account and they have no record of this phone & I've even had Samsung call talk to them but I dont wanna switch to tmobile to make an account to unlock it.. Is there any way to unlock it to use on a different carrier?
[Samsung Galaxy S9  Questions & Answers] jcsww:
Samsung or a third party unlocking service are your only options. Even if you were a T-mobile customer, they would not be able to give you an unlock for a device they did not provide.
[Samsung Galaxy S9  Questions & Answers] Youdoofus:
yes, but you ll need to buy an unlock code if you cant get it from the carrier it came from. I used www dot androidsimunlock dot com. Its $29, but it worked for mine and my buddies S9. 3 business day wait too, but i got both codes, and they worked seamlessly
[Samsung Galaxy S9  Questions & Answers] leftylok83:
Ok thanks
[Samsung Galaxy S9  Questions & Answers] Youdoofus:
no problem. it sucks, but it is what it is. i know there are cheaper places to get the code, but i cant speak from experience about how those other sites are.
[Samsung Galaxy S9  Questions & Answers] leftylok83:
Its all good I just want to use my phone again. Thank you for that its cheaper than the 1 I was looking at
[Samsung Galaxy S9  Questions & Answers] Youdoofus:
so, what carrier are you trying to use this with?

also, the HOME_CSC wont factory reset your phone, the CSC will. Pretty much the only difference between those files
[Samsung Galaxy S9  Questions & Answers] dovid:
At the time, I was trying to flash to TMobile. We figured out that we must have the sim card in for it to work.

Also, we are only able to get TMB/TMB/VZW to show up on the info screen. We cannot seem to convert that last VZW to the new flashed carrier TMB.

Any insight into that?
[Samsung Galaxy S9  Questions & Answers] Youdoofus:
why is that important really? i have a Cricket S9 and flashed the U1 firmware and it works perfectly fine. Is there an issue youre trying to correct? Is something not working? Or is it just a thing where you want a specific firmware set to show up in the phone info screen?
[Samsung Galaxy S9  Questions & Answers] jcsww:
The last tag of the 3 is the carrier or retailer that sold it. It has no impact on the firmware your device is running.
[Samsung Galaxy S9  Questions & Answers] supasieu:
Does anyone know if I can flash ROM on my Galaxy S9+ Dual Sim international to use with T-Mobile? The phone is working with call/text/data but data only give me 4G (speedtest around 5mbps), the LTE does not active. I've tried T-mobile and verizon sim card but same result. Thanks.
[Samsung Galaxy S9  Questions & Answers] jcsww:
4G is LTE and 4G+ is LTE-A. It's just an icon. You might get better speeds with a hybrid ROM, but you can't flash a full image T-Mobile firmware to an Exynos version of the device.
[Samsung Galaxy S9  Questions & Answers] supasieu:
Using the same SIM card on my Galaxy S8+ from T-Mobile I can get up to 100mbps speedtest, but on the Galaxy S9+ the max I can get is 5mbps. Do you know any hybrid ROM that I can try it out? Thanks.
[Samsung Galaxy S9  Questions & Answers] jcsww:
Carrier aggregation, radio tuning, and APN settings more than likely make the difference.

I don't personally use any hybrid ROM's but look for the T-Mobile Exonos based ROM's. They are essentially the Exynos base with the T-Mobile radio and CSC.
[Samsung Galaxy S9  Questions & Answers] supasieu:
Thanks.

just check imei on imei.info and it say the phone is

OS:Android 8.0 Oreo

Chipset:Qualcomm Snapdragon 845
[Samsung Galaxy S9  Questions & Answers] jcsww:
If you have a South American SnapDragon Dual-SIM device. That gets into a whole different mess. :P There should be threads on those too, just less common. Full firmware versions that have U1, U, or W in the model number, are all cross-flashable with the right steps.
[Samsung Galaxy S9  Questions & Answers] Youdoofus:
this problem is likely caused by the LTE bands enabled on the phone. One of the biggest obstacles to overcome when switching carrier IMO
[Samsung Galaxy S9  Questions & Answers] yan74s:
Hello

It seems that is impossible, I have the same problem but inverted .... I have an US model and I need an international one... Because I have LTE instead of 4G
[Samsung Galaxy S9  Questions & Answers] jcsww:
LTE and 4G are the same same thing! LTE-A and 4G+ are also the same. It's just an icon.
[Samsung Galaxy S9  Questions & Answers] Youdoofus:
they kind of are just icons. 4G and LTE are both marketing terms used to put something easily remembered on a technology that is far more diverse than LTE or 4G can properly label. They only made those terms for end user ease of operation.

the biggest thing ive seen is that the LTE and 4G icons will show depending on which bands you have enabled on your device. I know this because ive had this exact issue and was able to enable some LTE bands in the service menu which changed the connection icon
[Samsung Galaxy S9  Questions & Answers] supasieu:
Update:

I get very slow data connection (0-2mbps) from T-Mobile in most of the locations (surrounding Seattle area within 75 miles radius). One time I was in a Verizon store and got a speedtest up to 33mbps. Another time I was in central of Seattle and got 25mbps, then drove 1/4 miles away and it dropped down to 0.1mbps.

I'm not sure if I flash ROM will it help or sell it.

Thanks.
[Samsung Galaxy S9  Questions & Answers] yan74s:
I know that 4G is a commercial name for LTE...

But it's also a question of frequencies that are used by operators oin different countries.

My issue is that my US phone tries to connect on frequencies that are not the officials in my country.

That's why the signal is very poor, and theG/LTE very slow ....

I found a solution with the app NetMonster (free app in the play store) : with It, we can change the prefered network type, It helps, but not enough to change the prefered frequencies of the networks ...

i flashed U1 firmware just fine, it finished with no problems and showed my phone as U1 in settings, i tried to flash to TMO and it went back to just at&t, tried sprint and verizon too all said success but phone says erasing as it boots and boots with at&t logo, whats going on?, i like the U1 unbranded look but its clocked at 2.5Ghz wheras just the U is clocked at 2.8, 300Mhz may not be much but i would rather have that option plus unbranded at&t junk. what should i do?
[Samsung Galaxy S9  Questions & Answers] jcsww:
Do you have the SIM of the carrier firmware you are flashing to in the device when flashing from U1 to U? Are you using the HOME_CSC, because that prevents conversion?
[Samsung Galaxy S9  Questions & Answers] Youdoofus:
it sounds like youre flashing the CSC file instead of the HOME_CSC. These phones are all literally identical for the USA market and can easily have the U1 firmware flashed on it to remove all carrier crap. Thats exactly what i did with mine. Are you using patched Odin? I assume so, because otherwise youd be reporting failures with that.
[Samsung Galaxy S9  Questions & Answers] 17mm:
i dont have a sim card, using HOME_CSC to flash the new U firmware, like i said the U1 firmware flashes just fine its when i try other U firmwares that it says erasing as it boots after flash then boots as at&t again with no changes.
[Samsung Galaxy S9  Questions & Answers] jcsww:
The HOME_CSC prevents conversion by preserving data that needs to be wiped. It might flash successfully, but it isn't erasing and writing over what it needs to because the HOME_CSC is being used. Using the SIM card of the carrier firmware you are flashing to helps because it specifies what needs to be configured on setup. Otherwise, it will just assume you are going to be using the same carrier the device was originally configured for.

Hello,

On this April 13,2018 post by By jrockz3000 : “How to flash a AT&T Galaxy S9 SM-G960U with a T-Mobile Stock Rom?”

The 4/14/18 post It gives instructions: To Flash the SM-G960U to a SM-G960U1.

My S9 SM-G960U snapdragon AT&T unlocked phone with the locked bootloader. Being my provider is Straight talk, it won’t let me hotspot nor wifi call. So,I was hoping to flash to a SM-G960U1, and get rid of AT&T.

My question is:

Will this process work on my bootloader locked phone?

If it will, the U1 firmware, link in the post, appears to be different than the U1 at sammobile. So I downloaded both.

Thank you for your time and assistance.

Reviving this thread. I was having issues with my AT&T SM-G960U device because my carrier was though T-Mobile. My process was the same. Flash with a U1 rom then the T-Mobile rom. Just updated roms because my phone was already on andoid 10 (Q). I started with a U1 rom Here. Which ended up in a recovery loop. I was still able to get into download mode. I then flashed the latest T-Mobile rom here.

Hi there,

After update to A 7.0 my ZC520TL got some issues like infinite autofocus (so no photos) or poor battery life.

I decided to do downgrade, everything was fine but imei was incorrect, same as serial number changed to 111111.

There was no signal issue in central areas of the city, so i flashed it back to official rom 7.0.

I fixed imei problem by maui Maui META ver 9.1724.25.00 but i dont know how to write serial number from 111111 to my original serial number, i also looked other threads but no success.

Is there any way to do it?

I wanted to put everything stock and send phone to asus service for 6.0 downgrade or just sell this phone and get something with android with no issues like poor battery or not working camera after official update.
