    I have read on a old thread about downgrading PB OS to 2.1.668

    Nope, once you've load 2.1.0.840, you can't ever go lower than 2.1.0.668 (unless you corrupt your NVRAM and your
    PlayBook wipes itself back to 1.0).


    corrupt your NVRAM and your PlayBook wipes itself back to 1.0

    Is this possible to do ?
    Thanks!

    Welcome to the forums!

    It is. But if you mess up you get a 400 grams paperweight.

    I seriously wouldn't try it.

    Why do you need 1.0 anyway?

    had the latest v2.1.0.1753, managed to downgrade to v2.1.0.1526
    my crazy plan is to get somehow to 2.0.0.4869 and start dingleberry
    read posts about how BB blacklisted older versions, only downgrade one version, etc....
    if pb would return to v1.0, maybe it is possible to go up from there to 2.0.0.4869

    any idea, how exactly to do "corrupt NVRAM" in some-kind-of semi-safe way ?
    (I am already familiar with some "cfp" commands)

    thanks

    There is no semi-safe way. You do it and you hope you don't brick it for good. I'm not coming back to this thread, I don't wanna be involved with dead PlayBooks.

    If you really want do it, all you need is here in the PlayBook boards.

    Man, I would seriously consider this. My PB has become a paperweight. If I could use it to stream Hulu and HBOGo again, i could get use out of it and save myself from putting together a media PC out of old parts, just for streaming.

    My phone is just so much better at browsing and watching YouTube, I dont reach for the PB anymore. :/ Flash is its only good point, really...

    Of course it would brick since the minute you restore the PlayBook from the corrupted NVRAM (if you don't muck it up all together) you'll have to upgrade to the latest OS to get the PlayBook to even register.

    If you managed to install OS 1.0, contact me for help in preventing the forced update.

    Can not help extremely curious. Why do you want to go back to 1.0? Only reason I can think of is a desire to go back to the original design goals of the PB that seem to have worked only in a certain environment. 2.0 was already out when I bought mine so, have no personal experience with the original OS ver.

    You can root a 1.0-PlayBook. Am I right?

    Yes. Then there is a possibility of re purposing the PlayBook. Problem is, re purpose it to what? Any foray to the android world would require heavy development, which nobody in their right mind would invest into a now ancient tablet.
