Galaxy Tab S SM-T705- Flash Other Countries Firmware

[SM-T705] flash other countries firmware
Hi there,
I have bought an italian SM-T705 LTE device (T705XXU1ANF7/T705ITV1ANF1/T705XXU1ANF6) and want to flash a german firmware (T705XXU1ANF7/T705DBT1ANF1/T705XXU1ANF7). I already found posts which discussed the SM-T700 WiFi version (seems to be possible), but for the LTE version, I found only one statement which says "might give problems with the radio". I do not want to brick my tab, so I would like to know if someone already did that successfully (or even unsuccesfully) and if there is something special to do.
Thanks in advance, Markus

You will be fine.

Thank you very much, ashyx. I flashed the DBT firmware and everything went fine.

Looking stock firmware for SM-R805F

Hi everyone,
I just recently got a SM-R805N (Korea LTE ver) and want to change its region.
However the CSC variants in the stock only contains Korea telecom (as mentioned in the CSC thread by ecoco1)
I am trying to use the old fashion way: flash in the combination firmware, switch the CSC and then flash back to stock, in which, the CSC I am looking for is in SM-R805F version
However, I cannot find any free source for SM-R805F firmware online... all those available , also in this XDA forum, is only for bluetooth version.
Would anyone in XDA able to source the R805F firmware? (best to have both combination & stock?)
Thanks a million

Caution.
Since Gear S3 it is NO good idea to flash wrong Firmware nor wrong parts... to LTE variants...
You could end like this:

https://forum.xda-developers.com/smartwatch/gear-s3/please-help-bricked-gear-s3-sm-r765s-t3665558
I have no Galaxy Watch... but this means not I have no idea how dangerous it is... if you doing """experiments"""...
Example:
https://forum.xda-developers.com/showpost.php?p=78545468&postcount=74
Only as info.
Additional info...
Not tested what happens with CSC only... BUT be sure it is not less dangerous... because partition PIT is inside CSC and netOdin AUTOMATIC write this file to device...
Suggestion...
Study offline...
You can extract files with 7zip and compare...
rootfs.img needs some other Tools or Linux... or...

Thanks adfree, but its too late... I have already bricked my brand new galaxy watch...
Now the watch wont go into any mode below. All it does is have a flash of horizontally line screen, consistently.
continue
factory command
recovery
download (wireless)
Tried the method "press 2 seconds, release 1 second" does not work, think it corrupted the partition.
Only mode still work is "download" which shows the screen correctly. What make it worse is I reset the watch before doing this and forget to turn off activation lock (but I have my own user name and password, think that does not make it worse then?)
Appreciate if any idea on how to tackle this... am already thinking about buying the usb connector for odin flash...(hopefully something will make it work again...)

Suggestion, if you want try it self at home....
Look into this post:
https://forum.xda-developers.com/showpost.php?p=78545468&postcount=74
Look into Video...
You can also click around this Thread... to see diffferent "solutions"...
Security prevent netOdin use... IMHO no way without USB to flash again.
If you have POGO Connector... Odin...
Then try FIRST to flash SM-R805N...
I see at this time it is not leaked...
So you need luck to flash SM-R805N Firmware...
Hopefully Warranty Void will still:
0 0x0000
Seems 3 SM-R805N Stock Firmware leaked:
Code:
R805NKOU1ARK8
R805NKOU1ARJ6
R805NKOU1ARHJ
You can PM me... if you need Help with POGO...
Best Regards

Sent you a pm thanks very much, i have not yet able to watch the video as im at work, but i think i need the items below:
R805N stock firmware
POGO Cable for usb connection
anything else would i need?

Sorry to hear it bricked, here is at least R805N normal firmware, there isn't any combo firmware that I can find atm
https://www.androidfilehost.com/?fid=1395089523397891319

Thank you @deadman96385 for the firmware
Hi adfree, here is the photo of the "Download" screen
Now i need to get my hand on the cable to try it out...

Thanx for Photo. :good:
Good:
A
SM-R805N to see...
So sboot.bin is not overwritten...
B
Warranty void still 0 0x0000
So Knox not dripped... BUT you have to wait for final result after Repair Flash...
Not so good = IMHO bad...
Reactivation Lock is ON...
This means MORE f&%ing Security...
As "we" have only Stock Firmware...
If no luck then also Warranty Void Value will change... maybe.
P.S...
partition.pit aka PIT is 1:1 same between SM-R805F and SM-R805N... except the RSA 2048 Signature crap at the end of file.
Best Regards

thanks... I should be able to get the POGO wire mid next week, will update you the result....!

My Galaxy is back alive! Thanks everyone in this thread. Tested the following:
Install R805N firmware: Download mode: Works
Install R805F firmware:
Download mode: PIT fail instantly, without install
Download (Wireless): Able to complete the install -> Fail warning in red -> Bricked
Tried for combination firmware, or CSC only, same result
Guess I will never have chance to change my CSC then...? (Unless there is a combination R805N available which has all CSC countries inside?)

no i am not able to change, as mentioned above, the original firmware does not have other CSC included, flashing any other firmware will brick the watch
i think it will only be possible if R805N has a combination firmware release

Samsung Galaxy Watch Active2 SM-R820 Region Change Files

Hi guys,
First post, so please let me off if I haven't followed protocol properly. I have been looking at all the other threads and posts and I have come to the conclusion that this is possible, but I need some guidance:
Bought the watch second hand. Samsung Pay isn't available. Samsung Tech help believe the watch isn't from the UK. I also believe this to be true, as when it is reset, the first language to appear is German, before it syncs with the phone and changes to English.
So I would like to change the region from Germany to England to get Samsung Pay enabled.
I have downloaded NetOdin3
I am capable of connecting to the watch in boot mode through wireless.
I have downloaded the combination firmware and stock firmware from https://forum.xda-developers.com/sm.../samsung-galaxy-watch-mactive-2-gwa2-t3968437 where adfree posted the links.
This is where I am stuck. I am unsure if these are the right files for the UK, because that thread was to change it from Germany to "ser"
From what I've read I need to change some text in the combination firmware, but how do I do this, in NetOdin3? or some other program.
Secondly what do I need to change it from and to? I understand its to get the region from Germany to UK, but what is the region code for the UK?
I appreciate I am a total beginner and have probably just asked some real basic questions, however after reading the thread about the guy who flashed his 820 with 830 firmware and bricked it, I'm a little more worried about getting something wrong.
Cheers in advance

You have to change from DBT to BTU..BTU is UK CSC.

OK, thanks.
So do I need to edit the files that @adfree linked in SDP?
or are those files ready to go and do I need to edit some files off the watch somehow?
Cheers

Firmware to downgrade SM-R805F

Hello everybody!
I need the firmware R805FXXU1ESI1 to downgrade and change the CSC of my Galaxy Watch, but unfortunately I only find it in Easy-firmware, and I don't have an account there:
R805FXXU1ESI1 Tizen 3File | Easy Firmware
easy-firmware.com
I need this version exactly, because my region is ZTO and I need this base firmware (OWO).
Thank you very much in advance.

As per my understanding, I have to follow these steps:
1. Flash combinational firmware
2. Change CSC using SDB commands
3. Flash stock firmware
4. Install samsung pay
5. Repeat steps 1-3 to change CSC back to the original so that i retain mobile connectivity
@galaxys I have the same watch model but with Tizen 5.5. Would the same old firmware work with my watch also?

Thanks for your early reply otherwise i was thinking of giving it a try.
BTW i found that dialing *#272*IMEI# also change the CSC but did not try because people here are going for flashing firmware due to some reason only. Do you know why shouldn't it work on galaxy watch?

It may be a Samsung thing for not working, but haven't played with changing CSC...

@galaxys @adfree I could not find Tizen 5.5.0.1 firmware for SM-R805F anywhere on the internet. It was released on 15th march 2021.
Is it not available yet? I am waiting for it...

Change region to Active 2 Model SM-R835U

Hi guys!
I want to change the region to my active 2 LTE from US to Mexico so that I can use my Mexican carrier. I got it thinking it was globally unlocked but it looks like it's locked to the US.
I've seen some tutorials but they are for older versions (Tizen 4). This watch is on Tizen 5.5.0.1.
Can anyone please help me out with this?
Thank you very much

Looks like Mexico is OWO Region package... with CSC:
TCE
Step 1.
We need Combination Firmware...
Attached is slightly "modified"... only removed folder + 1 file...
Step 2.
We need OWO package of SM-R835F...
Best Regards

i need some help to not mess it up. since it only has one go through the wireless method.
thanks
