If L is abandoning the platform, what reason is there to NOT unlock the bootloader?

    I was thinking about it.

    Normally you wouldn't unlock the bootloader if you were selling the product as a loss leader and wanted to force people to use your software/advertising/etc.

    This isn't the case anymore for logitech. What other reason would they not unlock the bootloader for us?

    It seems like it would reduce support cost because people running their own firmwares will generally be smart enough to know logitech wouldn't support anything they didn't provide.

    I tried contacting a couple of people at logitech regarding this issue but I wasn't able to receive any replies. Curious if someone has insight on what I'm missing.

    Probably contractual agreements with Intel and Google. After all, the boot loader for the Revue is built into the CE4150 processor. That's why they have to use the Intel's Consumer Electronics Firmware Development Kit (CEFDK) whenever they build finalize a patch.

    I was wondering the same thing with Logitech dumping the Revue. Warranty won't matter as much anymore.

    Quick Q on the Revue honeycomb leaks. Were they binary leaks of kernel + Android, or do the community actually have partial source that's usable? Is the Revue bootloader checking to make sure the images are valid/signed (I assumed so since people are asking for unlocking the bootloader)?

    Thanks!

    That's an interesting point I hadn't thought of.

    I doubt it's with Google because I know HTC is unlocking bootloaders from the factory now. They are using ARM instead of ATOM though. Or at least previous phones have been ARM.

    Still though, what would Intel have to gain by locking us out? The Boot loader development kit is free I think.

    My understanding is that the previous firmware wasn't checking to see that the image was signed but the current firmware is.

    All the developer leaks were fully signed OS packages from Logitech. That's why there's not much in the way of "underground development" for the Google TV. In the second developer leak, they even removed the ability for user input while in recovery. Therefore, holding down the power button while the Revue is booting up will no longer initiate the USB update process.

    I believe it is more relative to Google than Intel actually. Google still needs to prove to the content owners that Google TV is a safe platform. Otherwise there's nothing to stop someone from overriding the HDCP copy protections if they have full access to the kernel. This is one of the main reasons that the Native Developer Kit (NDK) is still not compatible with Google TV; not even the x86 NDK.

    Remember, Google is still trying to smooze the content providers to embrace Google TV as a tool to enhance their product offerings. So, leaving a security hole that will prove that they do not have control over the platform will be seen as a threat to content owners and distributors. This is why "security updates" continued to be pushed by Google even after Logitech appeared to cease development for the 2.1 platform at the beginning of March.

    I really regret updating now. :( I updated the night I bought it before I did research.

    That does make sense. Although Netflix and Hulu plus both run on rooted android devices. I understand what you're saying though.

    Don't worry, you can still back rev to the previous update. So, if the GTVHacker community can get a hold of the OTA package then you should be able to get back on the official OTA release schedule. However, the process is a bit involved as it requires use the Android Debug Bridge (adb) client. Instructions for ADB here, "http://www.googletvforum.org/forum/...-set-up-your-revue-running-hc3-1-use-adb.html" or here "Updating to future USB updates from HC "User-Debug" leak"

    Awesome news. Sweet, I'm familiar with ADB. I suppose I'll continue being patient and wait for the OTA release since it's so close. Next year might be a different story in regards to future releases however.

    I guess they're still in denial that HDCP is completely broken.

    I'd post a link but I don't have 10 posts (and I will not try to get around the filter)

    Sorry, completely blew that one. Tried to access that website petition all day and guess what; it now works after I posted something here saying I couldn't access it. Typical....Nevermind, my bad!

    Another Revue user happy to sign the petition. Lets hope it gains some traction.

    I signed the petition but I haven't read the agreement between Google TV and Logitech to manufacture the Revue and can't believe it would permit opening up the platform but if it does, maybe it will happen. I have signed quite a number of internet petitions but I have never signed one that resulted in the desired outcome, in fact, I don't think I have ever even signed one that was acknowledged by the company being petitioned.

    • What is a bootloader ?
      • A bootloader is the code that loads and executes kernel. It kicks off before any piece of software on your device, and is responsible for loading the kernel which is responsible for loading the rest of the operating system.
    • Why is the Bootloader Locked ?
      • The bootloader is locked because the manufacturers do not want you use another version of the operating system.
    • Why Unlock Bootloader ?
      • Unlocking the bootloader allows you to install custom firmware on your Android device.
