[Samsung Galaxy Watch] orbifone:
AS always, AT YOUR OWN RISK INSTRUCTIONS/ADVICE!!

Device:

Galaxy Watch Active2 - RM-R820 (44mm)

WIFI Only Model - UAE Region Code

Status:

Device was initialized and updated to R820XXU1BSJ6

Tizen 4.0.0.7 (Latest at time of writing)

Backup health data only if you used the watch

The full backup/restore may bring information Region specific that you don't want

PROBLEM

=========================================================

Stuck in !!! UART !!! - Engineer Mode

(Were you can access and test all the sensors of device)

(Permanent Yellow and Blue writing on the screen)

(Every thing works including settings, but you have reduced apps and no wifi or bluetooth connections)

(if previously attached, the Samsung Wear app recognizes the phone. But that's all)

(The connections in wifi download and recovery mode work!)

=========================================================

Thanks to adfree

Downloaded the FT Combination file FT40_R820XXU1ASI2.tar.md5 (First Update???).

Downloaded the 3 Individual files smR820XXU1ASHF.7z (Original ROM???).

Connection problems for some:

- Shut down Antivirus, Firewalls, Internet and other connections on the machine

- Remove cable (usb) connections to other devices (phones, etc)

- Restart the machine if necessary

WIFI Download Mode

- Start netOdin first - adfree

- Activate phone Wireless Download after

- Connect to the phone access Wifi on pc (ie: RM820----)

- Check netOdin to register the link

- If not, try to restart one or the other until they acknowledge contact

Same for Recovery Mode

- used SDBstarterKidv1 from adfree page instead of the TIZEN sdb kit

- Hotspot you PC Wifi or use your phone Hotspot

- Disconnect other cables

- Make sure that SDB only sees the watch connection

========================================

I've used the FT combination file first!

Followed Post #51 Instructions.

- Thanks hashirajaz94 -

- I think that was the problem (tell me if I am wrong!)

- Follow first post instead!!

...

Step#12: click on AP in NETODIN and select the file from the combination firmware and make sure you have unticked AUTOREBOOT option before pressing start

Step#13: once you see pass status in NETODIN press reset, select CSC and select the CSC file located in the STOCK ROM file , also make sure you unchecked auto reboot before starting

Step#14: once you see pass status in the NETODIN, hold the Home button on your watch until you see rebooting splash and repeat the STEP#6

At restart Engineer Screen came up.

- With respect for hashirajaz94 post #51, follow the the first post instructions instead!

- I don't know if there is a difference for editing the CSC files, but use the AP from the 3 Individual files smR820XXU1ASHF.7z

- Some one will tell if I am in the wrong!!!

But, I followed the rest of instructions strait.

Used the FT40_R820XXU1ASI2.tar.md5 for AP, BL, CSC.

---

As others advice, to edit CSC the Region files

- use left / right navigation arrows for position

- use back key to delete the replaced letters

- use sequence 3 keys ( :wq ) + Enter to save the files

- you will get a red line error. But the files will be updated!

---

Restarted the watch.

Engineer MODE was still active!!!

Solution:

Started Wifi Download, netOdin and used the 3 Individual (AP, BL, CSC) files in smR820XXU1ASHF.7z

Auto reboot enabled.

The Engineer Mode came OFF.

All though older Rom version, seems more stable!!

Could we use the smR820XXU1ASHF.7z for the all process instead of the FT???

(I don't really know if the FT Rom was the problem or not!)

- The latest update R820XXU1BSJ6 is only 16MB download in Wear app.

Before pairing the watch, remove Wear app if paired before!

WEAR APP (One or more Phones)

- If the watch was paired before

- Clear DATA first and then UNINSTALL galaxy Wear app.

- Watch app plug-in will uninstall

- Non rooted devices are unable to remove Wear app

- Go to galaxy store and uninstall it from there.

- It will loop, but will uninstall and reinstall or reset

(because is as system app)

- You may want to restart the phone at this point

After that...

- Update Wear app

- Pair the watch

- It will install watch plug in

- Once fully paired, wait for or search for update R820XXU1BSJ6 from app

That should be it!

HUGE THANKS to first poster, file Uploaders, XDA

And all of you who resist the technology PIMPS to TOTAL CONTROL.
