    Galaxy Tab Firmeware Shows Locked Bootloader


    Well this is not something we like to see, but it seems the latest leaked ROMs point to Samsung as the next culprits to “let’s not let people hack what they buy” syndrome. These Firmware updates were leaked by Xda member Chainfire, who points out that the software come with a locked down bootloader, which prevents people from loading their Tab up with cooked ROMs.

    Here is what Chainfire has to say about this:
    This really applies to other ROMs as well, but the "new" JM6/A/C/D ROMs specifically.

    Some of these ROMs include new bootloaders. These bootloaders check checksums/signatures in various parts of the firmwares. The "normal" Samsung ROMs, nor custom ROMs and kernels, have these checksums.

    The result is that once flashed, you cannot revert to older/official/custom Samsung ROMs, and you are pretty much stuck using one of these four ROMs, as they are the only ones containing the right checksums.

    At least TRIPLE CHECK if you want to flash one of these ROMs, that what you are flashing DOES NOT include the new bootloaders ( boot.bin and sbl.bin ). I know from the CF-Root thread that a fair number of you are already too late, but I thought to warn new users anyways. Some modders (like rotohammer) already usually remove these parts, but still triple check everything to make sure.

    There is no known fix. I know, I've tried all of them some people suggested in other threads. None of them really works. Sure, with some effort, you can get a different firmware to somewhat run, but you'll still be using the "checksum" bootloaders and the kernel will not be modified. You will still be running the kernel from the "checksum" firmware you loaded earlier. You will not be able to do full flashes, nor will KIES updates work.

    Hopefully somebody will find a real solution for this issue for those already affected. If so, please post it in this thread.
    How does this make you feel? Is it fair for companies to do this?

    Spread the word through the web.

    More like Motorola, and their locked encrypted an Booby-Trapped bootloader on the Droid X. Why should we trust companies who operate like this?

    You can get it, just don't accept any 'auto' update notifications you get one you turn it on until you do your research (or better d/l one of the updates listed above that have the locking files removed).

    Yes it's fast stock but the debate is what rights does the consumer have to the devices they purchase, especially here where the device price is not subsidized by the carrier or the manufacturer and you are not bound by a contract containing an User Agreement.
    You are right to be wary. There is much bullcrap. Be wary of me too, because I may be wrong. Make up your own mind after you evaluate all the evidence and the logic. - Mark Rippetoe

    Well I was waiting on Gingerbread before getting a Tablet (as least for confirmation of which current tablets would get it) but either way this does not bode well for future devices... Might have to look a a Win7 tablet

    I thought this device was getting GB in the future? What is the deal with these bootloaders. Yea I though Motorola was the only ones who would screw us over. I wanted to get this tab, for one reason because I am sick of Motorola and didn't want to buy their upcoming tab.

    ^Since the Milestone, Droid X, Droid 2, and probably their other current Android phones have locked bootloaders.....its a safe bet that the Moto Tab will have one too....

    I was hoping against hope the Milestone and Droid X wasnt the start of a trend with phone manufactures...

    Even tho I'm more than satisfied with my X and I dont run any of the ROMs out for it, I do appreciate and recognize the beauty of my Droid 1...
