I am looking for firmware files for SM-T707a to update my Tab to Android 6 but currently i am on Android 5.0.2 ( Baseband Version: T707AUCU1BOE4) . i am currently not in USA and looks like AT&T wont allow OTA updates if you are not using AT&T SIM , as i tried several times to check update and every thing it returned a message saying my TAB software is upto date. Now the only way for me to update my Tab is to do it manually and i am looking for firmware files with Baseband version: T707AUCU1BOE5 released on 13th Aug 2015 so that i can upgrade to Android 6 eventually. I got Android 6 firmware (odin files) from this forum but i am not able to get this intermediate firmware file( BOE5) to enable me to update to android 6. Can any one please help me with these firmware files or can anyone lemme know if i can safely upgrade directly to android 6 without this intermediate update ?
Need T707AUCU1CPK1

search and read. especially about downgrading the bootloader
I believe, if you have bootloader version 3 it's not possible to downgrade. I have downgraded international unlocked Note 9 back to ARL4 version back in January. There is a huge discussion here on xda how to do it, but unfortunately I think it can't be done in your case.
Hi all,
My Note 8 is currently running Android 9 (official), with baseband N950FXXU6DSD3. Given the phone is turning sluggish day by I thought it would be a good idea to downgrade to Android 8. Well, I downloaded Odion and the official firmware for N950F but Odin gave me an error. Googled and found it is probably because the baseband / bootloader is l6 and the firmware I was installing was l5. However, I couldnt find any official android 8 version with bootloader l6.
Just wondering if there is an alternate was of downgrading without tripping Knox/ Samsung Pay?
Thanks!

Nope not possible you're stuck on bootloader version 6 and there's no going backwards now!
There is no Android 8 rom with v6 bootloader? Also, if I choose OEM unlock will it still trip my Knox even if I install official firmware?

No OEM unlocking will not trip your Knox flag. However, if you install twrp and root the phone that's when you'll trip knox. If you're thinking that toggling the OEM button will allow you to downgrade backwards it's not going to happen! I personally don't know of any Android 8 on bootloader version 6. This is why we preach not to accept updates or buy a phone that's already been updated because there's just no going back once you update! We haven't found a way to do that and I don't think anyone is actually spending their time to try to figure that out either.
Ah ok. Thanks. Guess I am stuck on a laggy OS.
Hey guys,
I have a question about my new note 9 I bought recently. So I bought the phone which was described as a Tmobile unlocked note 9. I noticed the phone is on android 9 still and won't update via the software update or samsung switch PC app. Says I'm on the current version and no available updates. I decided to try and flash the newest update but when I looked at the software information, I saw the following:
One UI version
1.0
Android version
9
Baseband version
N960USQS3CSJ2
Kernel version
4.9.112-16352588
#2 Wed Oct 23 12:37:16 KST 2019
Build Number
PPR1.180610.011.N960USQS3CSJ2
Service Provider SW ver.
SAOMC_SM-N960U_OYN_TMN_PP_0019
28f15f89d33f7ece
TMB/TMB/SPR
So if i'm not mistaken, this phone is originally from Sprint? How should I go about flashing the newest android 10 firmware ? for future updates as well?
Any help is greatly appreciated!
Thanks
It does seem that you have the Sprint model of the Note 9. If you cannot update the OS via OTA in the device. you would need to download the update from Sammobile and install it onto your device using Odin.

Thanks, that's what I plan on doing. Should I flash the Sprint or T-Mobile version of the update via Odin?

You can install either OS. Or the Samsung stock OS as all of those will run perfectly in the US variant of the Note 9
Hi ; my device is G975F Exynos and Original CSC is NEE. İ am on Android 11 Firmware which is G975FXXSEFUJ2.
i plan to go back to Android 10. i do not know my device's bootloader is unlocked or not. And also do not know is it available for bootloader unlocked or not.
What shall i do ? is it possible to go back to Android 10 for this device safely ?
I'm telling my own experience with my G973F, short answer: no
My phone has a unlocked bootloader and i have TWRP, i mistakenly flashed a wrong (lower) bootloader version, and my phone didn't boot anymore, i was only able to recover using download mode.
Older android versions have older bootloader, if you manage to install an older bootloader you phone will only give a message in the top of the screen saying something like "SYSTEM REV. CHECK FAIL DEVICE 8 BINARY 7"
You can only install a lower android version if that android rom works with your current installed bootloader
