Can we still downgrade software on Samsung mobile devices? - General Questions and Answers

Hi,
Saw on a reddit thread that Samsung has updated the RP (Rollback Prevention) Fuse version of Knox in latest updates, so we can't downgrade software if we are using the latest updates.
Is this true? If so, to what extent? Is this device specific or region specific?
Can someone provide some insight & info about this?

Galaxy S7 TELSTRA root.

Hi,
I recently updated my S7 (Australian Telstra model) and can't find any rooting available for it. Has anyone got a root out for Build Number: MMB29K.G930FXXU1BPIT yet? Baseband version is G930FXXU1BPIQ and when I click 'Software Update' it checks for a latest software and tells me it's the latest already with the current version: G930FXXU1BPIT/G930FTEL1BPIT/G930FXXU1BPIQ.
I also hear alot about 'tripping knox' when you root a Galaxy S7. Can someone please explain what is meant by this?
Thanks in advance.
Yes, knox WILL be tripped for the international model of the S7. No way to avoid that. Tripped knox counter means void warranty

Help Needed Regarding Updates.

Hi Everyone.
I'm currently using a refubrished Galaxy S8 plus, the model is SM-G955U.
As you can guess this is a phone destined for the USA market but currently I'm using it in Bangladesh which is in another continent.
As a result i didn't receive any updates after purchasing the phone and whenever i try to download update manually it says, "Registration Failed"
Can anyone help me to update my phone? I have attached screenshots in which you can see the current software version of the device.
Also if updating to official Samsung software isn't possible then can anyone suggest me custom ROMs for this model!
Any advice would be greatly appreciated, thanks!

You should get updates automatically irrespective of your location. Try the site https://firmware.science/ and select your phone and firmware version and follow the instructions .

Failed registration may be because of the fact you aren't using a US SIM card.
U models also.. don't have much custom ROM abilities. It's a locked Snapdragon. You can use firmware sites to be able to download updates respective of the model number.

S9 plus not receiving OTA after moving to another country

Hi,
I used to live in US and got an S9 plus from AT&T. I moved to India (in July 2018), got it unlocked by getting the unlock code and procedure legitimately from AT&T. Put a Vodafone India sim card. It works fine since but I have not received a single update since. Last update is June 2018.
In sw information Service Provider SW version shows
SAOMC_SM-G965U_OYN_ATT_OO_0073
.......
ATT/ATT/ATT
As I use this phone for work, our company mobile management tools prevent the use of rooted phones. How can I start receiving official OTA updates without tempering with the legit status of the device.
Thanks.

Because Vodafone does not offer updates for your model number. The carrier controls the updates and which devices are supported via update. Your device is not a Vodafone device, it is an AT&T device being used on the Vodafone network. If the original AT&T US stock firmware version is working fine, you should be able to download any updates that are available for your specific model number and then flash them manually.

Thank you for the answer. What will be the legitimacy status of the device after that? How do I flash manually an update? Do I need to use Odin or similar, since Samsung tools look at the CSC?
Thanks for your help!

Yes, use Odin. Find the updated firmware, just make sure it is for your specific model number and your region/carrier.

What will be the legitimacy status of the device? And where can I find a legit fw for G965U ATT. I couldn't find any so far.
Thank you for your help!

Samsung S10e not Receiving Updates (SM-G970U)

Hello guys,
I bought my brand-new Samsung S10e this year in early July and I havent received any update since the January 2020 security patch, which I assume was installed when the phone was manufactured. I was wondering if there's any issue with my firmware or anything. I have seen some recommendations for firmware flashing, I am a bit freaked out about it as I have never done it and I dont want to brick the phone. Additionally my phone is the US variant (Snapdragon) and New Zealand where I live has Exynos for the Default, further convincing me that the phone might have no compatible firmware for where I live to receive updates. I also read that it is not possible for Snapdragon to be rooted and so I was wondering if I could get comfirmation as to whether or not I could use custom ROMs. Any help, suggestions, or recommendations would be greatly appreciated, I am desperate for anything.
Phone model number: Galaxy S10e SM-G970U 128GB
Thanks in advance

Your best option is to download SamFirm 5.0 and download SM-G970U1 firmware XAA code. Youll get updates then. Search how to use SamFirm and tutorial how to flash with patched Odin.

Are you sure that I use the SM-G970U1 firmware and not the SM-G970U firmware, I just really don't want to screw it up, is there a link you could send so I'm not installing viruses? Thank you
