Can I flash T800/T805 custom firmware on the Austrlaian T805Y model?

Hey guys,
I would like to buy the Galaxy Tab S 10.5 model as it suits me more than the latest model, I also want to install this custom firmware once I buy the device http://forum.xda-developers.com/galaxy-tab-s/development/prerooted-stock-touchwiz-rom-t2973107
How ever upon further investigation it seems like Australian stock of the Tab S 10.5 are in fact this 'T805Y' model. So basically im wondering if the custom firmware above is compatible with the Australian T805Y model?
Should be fine as long as you update the firmware to the official stock so you are on the same base.
Just be aware you will likely be voiding your warranty unless you go the kingroot method.

SM-G960 vs SM-G9600 - Bootloader Question

Sorry for this if it is answered elsewhere but I didn't see a specific answer in my search.
I'm looking for the unlocked international version of the S9 because I want to root it, flash ROMs, etc..
I see the international SM-960 models that have the Exynos chip, which I know can be unlocked.
I also see the international SM-G9600 models that have the Snapdragon chip. Can the international variant with Snapdragon also be unlocked, or is it Exynos only?
In some strings I've seen mention of getting an unlock code from Samsung after 7 days. Is that for the 9600 (snapdragon), the 960 (Exynos), or both?
The SM G9600 has an unlocked bootloader like the exynos variants, but since there is no TWRP for the g9600 you kinda can't do much with it. There are no custom ROMs out there for the snapdragon version. But there are GSIs that can be installed thanks to Project treble. But like I said, without twrp you can't do much.

Hi, I've bought an 960U in the USA, and looking to flash the Brazilian ROM, but the variant used here is the 9600. Can I Flash It?

No, the SM-G960U (AT&T carrier locked version, IIRC) has a locked bootloader. I do not think you can flash any new firmware to it, unfortunately.
EDIT: Maybe you can, follow the guide in this thread: https://forum.xda-developers.com/galaxy-s9/how-to/how-to-flash-u1-firmware-to-device-t3765200
I'm not sure, but it may be worth a try.

Hi
I have the 960u unlocked, I bought it in a best buy.
This makes a difference to flash or not the 9600?

Carrier unlocked is not the same as bootloader unlocked. One let's you use any carrier SIM card the other let's you flash stuff.
I can buy the N9600 but I am not entirely sure if it will be able to get fully twrp working and root

S9 plus models that can be rooted

Can someone tell me which models of the s9 plus can be rooted and have custom roms installed ?
Iirc petty much any of them except the US carrier variants (960/5U)

Is it possible to install USA AT&T or TMob firmware on G9600 and root it

I'm planning to get the G9600 since the Exynos has battery issues.
I don't need to install a lot of custom ROM's , I'll be happy with rooted stock and microG, even though I see that TWRP and unofficial Lineage is already available for the 9600
If I need to use VOLTE and HD Voice on ATT or T-Mob, do I need to install the US firmware? If yes, is it possible to root the USA firmware since the 9600 has an unlocked bootloader?

Some questions about bootloaders, VoLTE on G9600 (SnapDragon)

I have the Latin America Snapdragon S9 G9600 with Oreo and using it with Mint Mobile (T-Mobile ) in the US
Have a few questions:
1. If I update it to Pie or 10 , bootloader will get updated. Is it possible to come back to Oreo by flashing stock ROM with Odin without root? Will that trip Knox?
2. Same question but if phone is rooted
3. VoLTE and WiFi calling is not working. Has anybody gotten those to work on G9600 or G9650 ?
