In this guide, we will show you the steps to change the CSC on your Samsung Galaxy Watch 5/Pro. While the fifth iteration of the watches brings in a slew of noteworthy features, however, you might still be missing quite a few goodies.

And in this guide, we will show you how to do just that. So without any further ado, let’s get started.

  • I can’t even get to the dialer because the 5 i bought (im in China ) wony even acknowledgr my phone/vice versa.

  • I am in China for 1 year. I just bought a watch 5 pro but cannot connect the watch to my S23+. My question is if the solution you proposed works with this watch. because my problem is I don’t have access to the watch menu at all. so I don’t have access to the dialer to dial the code *#….*#. If possible, offer me a reliable solution. THANKS

  • Stylianos

    Even with second option (odin) nothing changed. How can I change csc

  • The 2nd method worked for me we’ll.

  • NetOdin does not connect to the clock, although the clock says connected. IP not showing up in NetOdin

  • after installing the software from pc it still shows the same regions, how do you actually change the region when installing from the pc?

  • hello,do you have the firmware SM-R925 thank you

  • dear all,

    you need to put your watch’s IMEI number after *#272* and not the one shown in this article.

    • None of the codes (*#272*IMEI#; *#272*719434266344#) worked for me.
      I’m trying to use NetOdin but I can’t find R925 firmware to download it.
      Appreciate any help.
      Thanks…

  • Damn, I had no clue that it would even work but surprisingly it did! However, I have found out is the fact that this tweak might not work with every CSC Code.
