My favorite Android tablet, the I/O limited edition Galaxy Tab 10.1, received a small update today with version number KG4 (full version: HMJ37.UEKG4 P7510UEKG4). The only new feature the update seems to bring is the Videos/Movies app from Google, which is otherwise not available from the Android Market. Disappointingly, I don't see a new Movies tab in the Market, so literally only the Videos app was added and nothing else. What a silly way to roll out new apps, considering I had to reboot to perform it.

Since the Pulse app prevented the previous update KF3 from going through until I did a restore from the original system dump, I'm not surprised that Samsung is asking to remove any shortcuts or widgets linking to the Pulse app from any home screen prior to the update. How amateurishly evil.

Update: Apparently, the update restores stock recovery and possibly locks the bootloader, but since I was rooted, all I had to do was re-flash ClockworkMod recovery again from ROM Manager, and it booted into it just fine. If you're not rooted yet, I can't guarantee you will be able to do so as easily as before, as the bootloader may not allow flashing of unsigned updates anymore (it seems to be locking for some, but not others). See xda for further discussion.

No word on the retail Galaxy Tab 10.1s receiving this update yet.

To force the update, go to Settings > About tablet > Software update and press Update.

    Hi Artem!

    Thanks for the warning, but this news seems wrong or at least incomplete.

    I updated my Galaxy Tab 10.1 I/O and every thing's still unlocked.
    ClockWorkMod recovery's still here too.

    See the post here for a screenshot:

      Did your CWM disappear and did you have to reflash it?

        Still here = still here.

    Artem, can you please provide your proof that the bootloader no longer allows unsigned updates? The link you provide to XDA doesn't reference that at all.

    The Tab 10.1 is due out in the UK on Thursday and I have mine on pre-order and would like to know if I can still root it. If I can't, I'm going to cancel my order.

      That's the definition of a locked bootloader, and that's what the OP on xda says. I will look into whether mine was actually locked or not further.

        Still new to Android (SGT10.1 is my first actual device) so thanks for explaining. I was under the impression you can still root and CWM the locked bootloader version, so I'm not sure why it would be harder now.

        Guess I need to do more reading still. Thanks!

        Artem, it seems you confuse recovery and bootloader.
        No bootloader allow to install updates.zip, its recovery's job.

        Bootloader is what is ran just at power-up, then loads and start Linux or a proprietary flashing interface (like Fastboot or Odin)

        Almost no recovery allows to install test-signed or unsigned update.zip, Galaxy Tab 10.1 Google I/O edition was a very rare exception.

        Please re-read from trusted sources the definitions of bootloaders and recoveries.
        I suggest you to update the article as soon as possible, it confuses a lot of people.
        Don't hesitate to ask if you need more details.

          Can you clarify whether it's the bootloader's job to load recovery if asked for or recovery can be loaded irrespective of the bootloader? My impression is that the bootloader controls that. Am I wrong?
