After several coding attempts, my Note 2 LTE has finally been unlocked from EE.
It was on JB 4.3 but now I notice that it is on 4.1.2 but I'm unable to contact the unlocker at present.
I tried to do a software update to get back to 4.3 but get a message that 'your device has been modified and SW updates are not available'.
Does this mean that it was rooted to achieve the Sim unlock and if so, how can I tell?
Is there another way to revert to 4.3?
Download a ROM on Sammobile and update your phone with Odin or Mobile Odin.

Thanks for your help.
Does the phone have to be rooted for this? I've just been advised to run Antutu and according to that, it's not rooted.
TBH I'm a bit (OK a lot) scared to do something that's gonna brick my phone.
All I really want is a working phone with the latest updates.
No need to be root, if something fail you can reflash with another usb port until it works.
Hey,
Still a bit of a noob to the whole rooting process and navigating XDA forums, so I'm having trouble finding the information *I think* I should be looking for. Basically, my phone's just begun crashing periodically, multiple times a day: anything from Camera, Process System, Touchwiz Home Launcher, or Samsung Apps have "stopped working" / "not responding" before. Of course, my phone's warranty has expired, but my contract isn't up so an AT&T Store wont re-image it for me :crying:
Even I can tell, at this point, that it's either my OS that's failing, or it's my hardware. I figured the easiest way to test this would be to put some stable CyanogenMod on it.
The information I'm looking for is: "is this possible?"
AT&T Samsung Galaxy Note 4
SM N910A UCU2DOI2
Currently @ 5.1.1
Thanks for reading,
~Vita.
No it is NOT possible to use any form of custom firmware or to root this device. It has a locked bootloader that has yet to be cracked open and the future of that happening os very bleak to non existant.
As for reimaging the device go to the note 4 at&t general section on the forum and read up on using odin and the 5.1.1 image posted there it will wipe the phone and format yhe system and data partitions and reinstall it like a new phone just like at&t would do or the manufacturer if you sent it to them.
Good luck
Thanks for the response.
Sorry for the dumb question, but isn't Odin able to flash any firmware onto a device? The "locked bootloader" means that only the stock OS may be reinstalled? Why is this...
Also, it seems unlock progress is being made on the N910V. Maybe hope?
Thanks for mentioning Odin, I'll try re-imaging the phone.

Well the problem is the kernel the bootloader prevents the devs from using an unsecure kernel (one not created and signed by at&t) on the phone if one is used the phone stops boot and says it is an unsecure non at&t kernel and to take thenphone to at&t store.
Odin can only write the firmware versiom that is currently on this phone in this case it is 5.1.1 if you flash any other note 4 versoin such as 4.2.2 it will brick.
Sm-910a flash example
Update ver Official at&t 5.1.1 / currently on phone 5.0.1 or 5.1.1 = good
Update ver (downgrade)oficcial at&t 4.2.2 / currently on phone 5.0.1 or 5.1.1 = brick not good or odin fail
Update from another carrier such as tmobile or verizon for 910t 910v 910g = fail (do not attempt)
Until oir boot loader is unlocked there is nothing we can do to mod or use custom firmware on this phone any attempt leads to a brick requiring using odin to re-flash the latest firmware (5.1.1 at this time) in order to make the phone functional again.

So from what I understand, I could use Odin to flash the 4 files which correspond to the specific AT&T 5.1.1 SM-901A version of my phone (which is exactly what I have) to re-image the device and make it functional again. The problem is, I cannot find these devices on sammobile D:
Could someone direct me to these files? Or are they not out because AT&T sucks? Or, what.

I think so, I don't know for sure but we've been able to Odin from various 5.0 Lollipop releases back to KitKat so should be fine.
downgrading from 5.1.1 or 5.0.1 to kitkat is possible but with many many problem but form 5.1.1 to 5.0.1 i don't know maybe phone will stuck or boot loop
thanks finitetime for your reply
other question are there any news about root for 5.1.1 n910a

I am sure that you are referring to a sim unlock. A sim unlock and unlocked bootloader are two completely different entities. To flash a custom rom you will need to have your bootloader unlocked, which is something that a few of us are currently working on. Until then, no custom roms can be flashed on the att variant Note 4s. Take care
the boot loader says Qualcom secure boot : disabled ?
in the boot loader screen ?

Your phone is SIM UNLOCKED which has NOTHING to do with root, bootloader, or custom roms.

Sorry, was off the forum for the weekend. Spexwood was correct, that is sim unlock. Qualcom is for the sim IE network. Take care.
Root is possible btw
Root is possible if youre willing to dedicate 10-30 hours of repititive root fails
How?

Hi All,
My apps are updating fine and i see that android 10 has been out for a few months now yet my Note10+ SM-N975U is not updating at all. it seems my security patches are still stuck on august 2019 and every time i try to OTA update, it says my phone us up to date. Is there anyway to bypass this. I see everyone saying to use Odin to update my phone but i am not familiar with the program and where/how to source the note 10 update
Id greatly appreciate the help as its affecting many of my apps

+1 for me. Ive spent almost 2 years and 3 phones trying to get an answer to this. My note 8 had this problem, then my note 10+, then the replacement note 10+. At&t blames Samsung, then Samsung blames at&t, over and over and over. I even had a Samsung technician sit in on a 3 way call with an at&t technician for the better part of an hour. The last I heard was that at&t was petitioning samsung to fix something on their end because at&t shows that everything is up to date on my phone but its not. Im looking into Odin too because this is getting stupid.
At&t is horrible with OTA's. They work for some but for a lot of people it does not, and I am one of them. At&t has never been able to give me an answer as to why this happened on my Note 8..9..and 10+.
Odin is very easy. You dont have to use At&t firmware you can use any Snapdragon US firmware they are the same. Once its installed, it will provision to you sim. There are many threads that have the firmware needed or just us Frija to download the firmware. Once downloaded you need to extract the files. You will have BL..AP..CP..CSC...HOME_csc. You need to download the correct version of Odin to flash the firmware. Open Odin put device in download mode connect device. Once odin recognizes devices find where you extracted the firmware. In odin put BL in BL spot..AP in AP spot..CP in Cp spot. If you want to save data, put HOME_csc in CSC spot. If you want clean install put CSC in CSC spot as it will wipe device. Once you have everything where it should be click start and Odin will flash the firmware. Once complete Odin will say PASS at top left..boot time should take a few minutes. But remember if the firmware you flash has a higher bootloader you cant downgrade back to previous version.

So I can use a verizon csc and it will work on a att branded phone? Or is a generic one better?
Edit
Basically which one do you pick. I'm leaning towards a tmobile because it sounds like the included bloatware is smaller.
I have At&t device purchased at At&t. I have used USC..Tmobile..Verizon. The device will provision to your sim. If you dont want bloat just flash U1 firmware. But I think you will lose advanced features like wifi calling if you do. I cant remember if flashing a (U) csc with U1 firmware brings back advanced features. But prob just stick with 1 firmware until you have a understanding on how to do this...Good luck.

I actually went ahead and did this last night with the tmobile firmware and it was just as easy as you said. For whatever reason I didn't even get any bloatware. It booted up with the at&t logo and sound, and my software version says att/att/att. I put my sim card back in and there were no special notifications or anything, everything just worked. I wonder if Frija gave me the att firmware despite me putting in tmb? Either way, everything is up to day now. Thanks for the help!
Anytime my friend glad it all worked out[emoji106]

Hi I have the same problem. I flashed android 10 One UI 2.0 on my Exynos Note10+ SM-N975F last December via Odin and download the firmware from Samfrew(like Sammobile).(the firmware is the German version and I bought my phone from Egypt) Since then I didn't receive any security patch updates I only have the December 2019 one. Will it be safe if I download the latest firmware from Sammobile and flash it; the file in over 5GB , can this overwrite? I never tried to flash the same software two times. Is it safe?
As long as you are using the firmware that is for your device and your region you should be fine. Although this is Snapdragon thread I would think International flashing is same. You may want to double check in your device specific thread as I don't want to be the blame if there is something different with F version.

Also try turning off auto update date and time. Set date like 5days ahead. Then check for update. Sometimes this little trick works for OTA

Greetings,
I'm super new here, also a tech noob so pls be gentle.
I purchased an unlocked At&T Note 10+, and i am living in Malaysia. Little that I know At&T would never send updates to out network, and that I require an At&t SIM in order to get the updates. Currently I am stucked with Android 9, ONE UI 1.5, with no hope of getting anything higher than that.
My question is, how can i get the updates besides flashing a new firmware? I tried connecting to Smart Switch on my laptop, and all it can says is that my software is up to date on SJ8 (ATT).
Hope there's a way other than flashing. HELP.

Hi Mohd Azrimny,
Am in the same boat as you. In Malaysia and have the note 10 plus at&t version. How did you manage? I am using Odin and getting error message connection failed. Not sure what is the problem.
Can you point me from where you downloaded the firmware? I am suspecting that is the culprit.
Thanks!

I'm sorry but I don't think there's other way around, you'll need to flash another firmware.
I have an Unlocked Verizon Note10+, the first thing I did after getting it out of the box was flash the unbranded firmware (CSC: XAA).
Ever since, I've had OTA updates as quick as they're released for N975U1.

I see...tq man. Can u help me out with one last thing? As they are thousands of firmware out there, which one should i choose? Can i simply choose any unbranded firmware (N975U1) from any month security updates n just flash it? I just need a stock ROM, not the latest should be ok as the OTA will take care of the rest.
Right now i'm at nov 2019 security updates SJ8 (ATT).

Well, unfortunately I'm not sure about previous versions, however I'm leaving attached my SW information, my CSC is XAA.
You can download it from sammobile or frija (this is way faster).
Hope this helps,
Regards.
So, knowing you are a noob is half the solution already...
I highly recommend you look for Frija on the internet. Download the tool, search for the phone you have , it is a SM-N975U , and since you want to get rid from the AT&T version, you can install the SM-N975U1 version with XAA as CSC, that Samsung themselves push updates to. Even if they will not, you can always download the next revisions..
I assume you know how to use Odin..

No worries, as Odin and the phone check revisions and suitability. If not the right firmware, it should not write it.

Hi all,
I am trying to reflash the unbranded firmware back on my unlocked S20 Ultra with Odin 3.14.4. I was able to flash the T-mo version, and currently my phone is tmo branded, so that worked, but everytime I try to flash back i get the SHA256 error. I do not know if it is because I am trying to flash the wrong firmware or I am doing something else wrong.
Can anyone point me in the right direction?
Thanks everyone.

Ensure you don't any other usb devices plugged into the pc.
Thank you for the reply, that is not the issue though. Tested re flashing the Tmo firmware that is currently on it and it flashed ok. Its just tryign to reflash to the original unbranded that fails.
Got the answer. I needed to use the patched version of Odin

So I installed and it went back to the stock firmware. No longer do I have the tmobile bootscreen or additional software. What I am concerned with though is I tried an OTA update and I get: Your current software version isn't supported. Visit a service center.
What can I do about this?

If you used HOME_CSC, that might be your culprit.
I had this issue when I flashed TMO firmware on the unlocked phone. With me being lazy, I didn't want to start from scratch and flashed HOME_CSC to experience this exact issue. As soon as I flashed with full wipe, this issue was solved.

Yes, that was the reason I initially put the tmo firmware on. So the samsung messages app had RCS. With the stock, I have lost it.
