hello , follow this tutorial Works 100% https://www.sammobile.com/forum/showthread.php?t=39155
Hello Experts,
I have a US ATT SM-G960U. I got it network unlocked outside USA. It is on Android 8 and when checking for updates, it always says its up to date. I also tried through SmartSwitch and its the same. The last security patch was from June 1, 2018.
I have downloaded G960U1 Android 9 with April Security patch from SamMobile and Updato. If I update my mobile through ODIN,
will SM-960 U1 patch work fine with my device?
will it lock the device or will the network unlock still be as is?
will I be able to use the device with other carriers?
will I be able to update the patches in future?
will it affect my device?
Please suggest,

Please help :crying:

The problem It's only with the July security patch. But you can no longer downgrade the software, now you have another binary. The only option you have left is to wait, or write to SamKEY support to solve your problem. So they can make it compatible with the latest versions of android.
Get rid of your IMEI number from your post. You never want to post that publicly.

Its nothing to do with Samkey. It maybe a new bootloader was released in the latest samsung updates preventing everyone from going back to previous version of software.

the fact that hes in here posting help for sometjing that samkey provides as a paid service that im sure no one in here knows exactly how they do it in the fiest place since if they did they wouldnt need to pay for it with samkey then he should ask them directly for help or why etc. as they are the only ones that could help him really..
but yes, if bl/rev was incremented we can assume they changed something that broke it and yes, if rev was incremented u cannot downgrade, this has been a thing for years n years now..
so the last part of ur comment, yes, samsung puts something in every firmware when they increment the revision that prevents u from downgrading, that likely doesnt matter tho since they probably added some security or changed something that broke the way samkey changes the csc so it is entirely on samkey thanks to samsung and samkey will have to fix/update their methods
I got the same error, wrote on support and their answer is:" Mr. Amin17:07 Not supported". I changed csc in May and it worked fine, it doesnt work now. I also tried downgrade FW but it stuck at boot.img (odin).

Your device firmware security versionis Bit3 not supported by samkey or any other 3rd party tool at the moment. Next time check samkey.org if your model is supported first. Also use ebay sellers like STAI30 who can help you with technical questions and sells 1 or 2 credits if you dont need 3.

Samsung frequently updates their firmware security and once you have upgraded there is no way to go back to an earlier security version. You can tell your security version by checking the first number after the letters following the device model number eg. G981NKSU1ATED model is G981N then the letters KSU follow and then the security bit which in this case is 1. For G988B if you check supported models at samkey.org you will find that BIT 3 IS NOT SUPPORTED so if you check your firmware and haave a 3 or higher at the security bit location it wont work. You just have to wait until samkey updates to support it. Usually all the 3rd party tools have the same limitations so chimera tool also does not support bit 3 etc. You can get the cheapest samkey credits from user stai30 on ebay any quantity from 1 credit and up
SAMKey now supports the latest firmware versions. Please try again

Hello,
I am new to the unlocking stuff.
I just bought a used ATT Note10+ 5G in Malaysia, model SM-N976U
However the security patch was stuck in May 2020. It could not be updated over the internet or Smart Switch PC.
It says it is the latest s/w (the latest should be July 2020)
I checked Sammobile and discovered 2 firmware updates : USA(TMK) and USA (T-mobile)(TMB)
(tried to include sammobile link here but was disallowed due to new user status)
Which firmware is suitable for my phone?
Is there a way to unlock ATT and receive the normal monthly security update over the internet automatically?
(i saw Odin in youtube and have basic idea how to flash it)
Appreciate any advice. Thank you

A thread already exists with the answers to your questions.
https://forum.xda-developers.com/galaxy-note-10+/how-to/att-note-10-5g-n976u-firmware-files-t4059721
No unbranded firmware version exists as of yet.. so you will have to flash a carrier specific firmware.

Thank for for the link provided.
Based on the link information, i can download the 4 base files from sammobile (either TMK or TMB) and add USERDATA ATT N976USQS3BTF4 to flash it.
Is that correct?
I could find USERDATA ATT N976USQS3BTF4 in easy-firmware website with a purchase fee.
(editied: My phone Active CSC Code is XAA, CSC Country is USA)

Hi SCitta,
Fellow Malaysian having the same problem as you. But my problem now is that I have Odin and the latest firmware (XAA) but Odin is showing failed to establish connection. How did you do it with yours?
Am using the AT&T version of the Note 10+.

Never experienced the failed connection before.
Have you installed the SAMSUNG-drivers ? The Samsung Smart Switch PC installation might help to fix the drivers.

Just want to share my experience in this. Bought an ATT N976U from the US and using in Malaysia. Phone came with XAA/XAA/ATT and never received OTA updates.
Downloaded Google phone app and changed CSC to TMB/TMB/ATT using *#*#27262826#*#*
Voila. Received the OTA updates one by one since May2020. Am now on N976USQU5EUC2.
Volte is also working on Celcom.
Did not have to flash firmware. Data not wiped. Everything seemed to be working normal apart from "Tips and Help" in settings crashes every time I click it. Also phone boots with T-Mobile logo now.
Hi all does anyone have the combination firmware for 520FXXUGCTKA? or even a latest guide to bypass?
I have check multiple guides and I can't seem to bypass FRP, the sim trick doesn't work on the latest build
The closest combination firmware I've found was FXXUF but not on for FXXUG
Any help would be appreciated.
