Unroot/Relock bootloader - Galaxy Tab S Q&A, Help & Troubleshooting

I know Knox will stay tripped, but how do I unroot/flash stock? Using netflix was 50% of what I used this tablet for and now that they blocked root, I can't watch it anymore. I tried to use magisk, but it doesn't work at all for me on cyanogenmod. If anyone can recommend a rom that magisk 100% works on, without laggy videos in youtube/twitch/netflix, that would be awesome! If not, can someone link me a way to unroot/relock the bootloader so that I am able to use netflix again. I'm currently running cyanogenmod 12.1. Thanks!!

Just flash back the official ROM, your tablet status will be official but the Knox count won't change. Search sammobile for your model, if you can root then flash back official firmware is not a problem.

Region doesn't matter, I have SM-T580 runs Germany firmware, SM-P580 runs Korean firmware because both are Android 7.
You can take the Australia firmware. Fact you should know: all Samsung tablets sold around the world are the same tablets, the difference is software customized to certain region.
Open a tablet sold in Asia, it's the same as the one sold in US, if loaded with US firmware, it becomes an US tablet.
I have one US tablet with Google Locked, downgraded it to Hong Kong firmware to bypass Google Lock, then upgraded it Nougat with Germany or Korean firmware.
I doesn't matter which firmware I loaded as long as English is my language of choice. Every region, you see the CSC ( Customer Software Customization ) file along with the AP file, that's the difference.

[Q] Want upgrade to 4.4.2

Hello.
Just bought an used Note II. It has 4.3 and I want 4.4.2. Software updates on the phone tells me 4.3 is the latest. Kies on imac is telling me the same.
Baseband version: N7100ZSENA1
Current firmware = Latest firmware = PDA: NA1, PHONE: NA1, CSC: NA1 (TGY)
It means that the update is not ready for that country? What country is NA1 (TGY)? Can I change that somehow and get the latest firmware?
Thank you in advance.
Update might not have arrived on your country. But you can get the ofiical firmware from here and instructions too. http://www.sammobile.com/firmwares/3/?download=28988
Thank you.
I'm also interested in knowing which country is NA1 (TGY). According to http://forum.xda-developers.com/wiki/Csc, TGY is Hong Kong. That means the phone was bought from Hong Kong?
If i flash that firmware, it will change country to India and will have OTA updates when available in India?

I would advise you flash the French Version and not the Indian version cause it carries the modem file that is tailor made for Indian users only,people who use that modem outside of India might experience sudden battery drain and weak signal (the ones that are rooted can take care of it by flashing the french modem or one of the older 4.3 modems) but you wont be and you'd have to flash French rom which carries a XX labelled modem that works for most EU countries although XF is the one for romania
http://www.sammobile.com/firmwares/3/?download=29588 - is this the right one?
Will this be enough? Or do I need to flash a different modem firmware? After this the phone will be french version instead of hong kong version?

Ya thats the latest one that released today.Download it and flash via pc odin.I am not too sure if your phone would change to "french version" look at my screenshot of attached CSC .Shows BTU (which is UK) and CSC country is UK AND IRE (cause i believe the stock rooted ROM from the developer i got turned the CSC into this i guess he's from that part of the world) and my note II is originally from Dubai and been using it in India .So you can imagine by poor phone has been touringaround the world..LOL But doesn't affect me cause i never upgrade to stock roms from sammobile i always get the stock dedoxed pre rooted ones from xda so CSC doesn't matter to me unless it messed my phone up.
Read this post below that would give you more info about how does flashing a rom from another country works

This is mine. Should I go then for french update or wait for hing kong version.
Is it ok that I'm using hong kong version in romania? France is closer
Ok, I did the firmware update from France.

Is this ok? Do I need to do anything else?
Battery life seems worse on 4.4.2. Should I flash different modem firmware?

Since you are on stock 4.4.2 you got two options,either flash a custom 4.4.2 custom ROM (dr ketan's rom is the least bloated and very close to stock)so that would give you a good estimate how your battery drain is or you flash a custom 4.3 (there are tons available out there choose the one which impresses you the most)
For now I wish to stay on stock ROM. But battery life on 4.3 was much better than on 4.4.2.

Well give it few days and see if it improves ,if it doesn't then only option is to root your phone and try custom 4.3 or 4.4 ROMS.Good luck

Why not give it a try? The 4.3 stock firmware should be on sammobile's site. Why carry another battery when you don't have to?
Assuming you upgraded (as in kept all your apps and data) from 4.3 to 4.4.2 then you should probably factory reset before judging battery life. Some apps just never play ball again after an update.
The rule typically is:
x.x.a to x.x.b - wipe only if experience issues
x.a.x to x.b.x - wipe suggested but not generally required
a.x.x to b.x.x - wipe generally required

Na no problems with region lock. it might trip knox, mine was tripped at 2nd flash. You may have to flash more than once to get it working.

Flashing with different region firmware.

Hi guys, I have Galaxy Note 10.1 SM-P605. My one is most likely a Malaysian variant. Baseband version: P605XXUCOE1. I still haven't got the lollipop update on this variant. Now kinda planning to flash it with the Finland version. So I have some questions here before I do...
1. Will there be any sort of problem because of different baseband/ region?
2. Will I have to face any issue with knox or official OTA updates in future?
Thanks in advance.= :fingers-crossed:
I can only answer half of your questions, as my device is rooted, so i don't get official updates anyway. Flashing a different region firmware never caused me any troubles, not on my 10.1, or my Galaxy Note4, so it won't affect the functionality of your device.
As for Knox, it will trip Knox as you are flashing a kernel not for the same region...
It may just bootloop. Make sure you have a stock rom to go back to, mind you this may not work if the bootloader is upgraded to a newer version, say KK to L or L to MM....

Glad to know man, btw I am having only 1 problem that is it's not showing my operator's name on lock screen or in connection settings, instead it's showing the 5 digit number code of my operator. Thats not a major issue I guess, must be some conflict with regions.

Austrailian Lollipop on US M919?

I don't have my phone rooted and I'd like to upgrade it to 5.0.0 lollipop. I see Samsung only put out the update to other countries and not the US, how nice of them.
Would I even notice a difference using it or would putting the Aussie version of lollipop on my US t-mobile phone be a no no?
Thank you
You cannot flash an Australian stock LP ROM to the USA T-Mobile phone via Odin.
There is a T-MOBILE Australian lollipop upgrade on Samsungs website for the m919. For verification, It won't work on my m919? Would u mind to help me understand why?
Thank you
The bootloader in the rom will be compared to the hardware being flashed. If it's a match, it will flash but not necessarily function properly.
If the Australian m919 is the same as the hardware as the USA variant, it will probably flash but I don't know if it will work n properly.
Ok thank you for the explanation
Why don't you install Lineage which will put you into >7.0

Downgrade to Android 12, One UI 4 - because of broken ANT+ Support?

Is there a possibility to downgrade to the last Stock ROM?
How to do this?
It's because of the broken ANT+ Support. Custom ROM with ANT+ would be great too, but I can't find one with working ANT+. Any recommendations?

You can flash Android 12 Firmware using odin.
Just download firmware files from Frija by typing your phones model number.
As for the CSC, the only one I know of with Android 12 as of now is KSA.
Once you get all the firmware files, place them in odin and flash while your phone is in download mode.

Thanks for your swift and helpful reply!
Is the wrong CSC a problem? I would need DBT for Germany unbranded.
Dispite of this, I can't find a Android 12 Firmware for my SM-G980F with Frija - not even with KSA.

Wrong CSC shouldn't be a problem as long as you have a sim card installed, but then again, it doesn't matter anyways since you want to stay on Android 12.
The S20 got updated into Android 13 in most countries.
Second way to do this is via those websites either Sammobile or samfrew where you just input your Phones model, CSC, and select what Android version you want.
