Because this is Account App related... rcz4775900...

All I can say...

NO Account is need to download Apps... :angel:

This Demo Store from XPKD6 is not the same... what you maybe expect...

Its only an example how important/powerfull KonaConfig.ini is...

Btw... compare KonaConfig.ini from XPKD6, normal Kona and from "Andromeda App"...

[Barnes & Noble Nook Tablet] pokey9000:
I now have proof that the Nook Tablet is efuse locked and bootloaders signed. We can only boot signed bootloaders, kernels, and ramdisks from microSD.

Don't buy this if you expect any real development to happen on it. The only possible way is through kexec, and that's a lot of trouble to go through considering all the other tablet options.

For what it's worth, the u-boot in the recently posted update image from the Kindle Fire does not appear to have the signed header that the one on the NT has.

Things I learned in the process:

-USB boot is enabled, as is SD boot

-I can boot from a microSD if I format it the same as for Nook Color (modified CHS, fat on p1) and copy the MLO, u-boot, and boot.img renamed to flashing_boot.img

-There is a serial port inside that will let you at the u-boot console and a shell after the OS boots

-x-loader is signed. A known-good x-loader on microsd will not even execute, and the next item in the boot list checked (emmc)

-u-boot is signed. I know this because a known-good u-boot from Pandaboard that should be close enough to boot causes x-loader to take the code path where the secure ROM call with a pointer to the image returns nonzero

-kernel and ramdisk are signed individually in the boot.img. I can modify a byte in the boot.img on the microsd that's in the middle of the kernel or the ramdisk section and u-boot will fail the same exact call that x-loader uses to validate u-boot, but this time emitting a message complaining that the image is corrupt

-Comparing the first part of u-boot grabbed from the NC, NT, and the KF, shows that the signature that's at address 0 of the KF and NC versions is seen about 300 bytes into the NT version, with some unknown junk above. I assume that's the signature, and that the call to the secure ROM returns the image pointer (which is passed by reference, a good clue) plus the size of the header.

[Barnes & Noble Nook Tablet] boomn:
That's certainly... interesting. Definitely not the direction I assumed they would go given those quotes from the B&N guys that have been thrown around.

I'll hold off any true disappointment until more people have had more time to poke at this thing. Nothing against you pokey, and thanks for your investigations so far.
[Barnes & Noble Nook Tablet] pokey9000:
Close enough to the one for Pandaboard minimal Linux, which I tried.
[Barnes & Noble Nook Tablet] diamond_lover:
I hope we can find a workaround, there will be a way to do that, because they installed android in some way.

BTW, have you tried a bootable SD card? I think it's the right path to follow.

EDIT: I see you can't boot by sd card.. what about if you try some file from Nook Color?
[Barnes & Noble Nook Tablet] aludal:
pokey9000: what kind of a response you can get when trying to boot your test SD in BB Playbook, I wonder?
[Barnes & Noble Nook Tablet] pokey9000:
Trust me, I've tried every trick used when we figured out how to boot on the NC.
[Barnes & Noble Nook Tablet] discothan:
might need some combination of keypress while the thing powers on...

I bet BN built-in some backdoor 'boot off SD' mode. This would allow them to grab the Nook Tablets and reformat the onboard space/memory however they see fit.

This was done in the past with the NC.
[Barnes & Noble Nook Tablet] boomn:
I agree, but it sounds like the problem is not with it blindly skipping the SD card but with it not seeing a signed image on the SD card. In that case B&N might just be providing their stores with SD cards with a properly signed image that doesn't need any other tricks
[Barnes & Noble Nook Tablet] jasoraso:
If B&N really is requiring signed images to boot from the SD card, I guess there might a different method to change the bootloader - after all, most (all?) phones won't boot off of a SD card, and it is still possible to change bootloaders on many of them.

BUT, I don't think this device is going to have nearly the same dev support as a year ago to discover/crack the bootloader issue.

I'll wait a little bit longer, but the quick progress rooting the Kindle Fire makes me think that that might be my next device to replace my lost Nook Color.

Sorry B&N - you might have lost me!
[Barnes & Noble Nook Tablet] nexus14:
agreeed. there's so many low-cost devices out there and devs are going to have to pick "sides": kindle fire, nook tablet, and who can forget the hp touchpad
[Barnes & Noble Nook Tablet] RussianMenace:
Considering most people havent had this in their hands more than 24 hours, I think it's a bit premature to make any calls.

That being said, I'll be holding on to my $$ a wee bit longer it seems.
[Barnes & Noble Nook Tablet] Ellerbestyle:
I really hope it can be rooted and then be able to put ICS on it. I guess I will hold onto my money a little longer also.

Even though I want the NT more, I would get a KF since it can be rooted.

You should really consider giving the Tab 7+ a try, even sight unseen. It's pretty nice, I think much better than the 8.9, also has microSD, don't think the 8.9 has that?
[Barnes & Noble Nook Tablet] bg2:
If you only boot from the SD card this is not even a concern because there is no way for B&N to push an update. If you happen to stray into Emmc, don't setup wifi and you are not in danger of unwittingly dowloading an update.
[Barnes & Noble Nook Tablet] madsquabbles:
no mSD, but i don't plan on putting many movies or music on it. it's mostly an ebook/comic reader. my gt 10.1 is the movie player - although my archos 101 is far better with different formats.

my tablet collection is getting too big. i've already sold my og ipad and nook color earlier this year. if some positive moves are made on the nooktablet i'll probably get one also.

honestly the nook tablet and gt 7 + both have better processors than the gt 8.9 and 10.1, but for what i'm using the 8.9 for it's not really much an issue. on the 10.1 i hate having to convert my videos just to play on that specific device. heck even the old gt 7 plays back movies better.
[Barnes & Noble Nook Tablet] PaulLeahy:
I want to start by saying thank you to any developers working on the NT, good luck, and godspeed.

Frankly, I'm fairly (if not completely) satisfied with an unrooted NT that can sideload apps and run them on an android launcher like LauncherPro. What do you all think is the possibility that B&N can/would lock down the ability to sideload apps?
[Barnes & Noble Nook Tablet] rmm200:
Well before launch, almost no one would have expected them to put out a signed bootloader. It was expected to be like the Nook Color, which worked out very well for them.

I would say don't make predictions on what B&N is likely to do...
[Barnes & Noble Nook Tablet] John Kotches:
that is the raw parts cost but there's more to the cost than the bom (Bill of materials). there is cost to build/assemble and many other amortized costs that add into the bottom line.

many people don't look beyond the bom but that is a quick path to bankruptcy for a business.
[Barnes & Noble Nook Tablet] Drewmungus:
You are half right. HTC released a unlock tool to unlock the bootloader.The bootloaders are still locked from the factory. It did work,it only takes minutes to unlock the bootloader.

The real down side is that every body who did the official htc warranty. But as far as I know that hasnt stop anybody from getting replacement phones at a sprint store.
[Barnes & Noble Nook Tablet] rmm200:
That would be a really satisfactory solution for B&N to take - release an unlock tool with the understanding that it would void the warranty.
[Barnes & Noble Nook Tablet] Meeker:
I think the problem with that is that BN has absolutely no incentive to do that? Much like Amazon, I think they need to realize some sales from the nook store in order to make the Nook viable as a business?

Else you've get dirty canadians like me... looking at the tablet and thinking of rooting it to get Google Apps working so it's be... you know... useful outside of the states :P
[Barnes & Noble Nook Tablet] MonkeysInACan:
Im liking that route. Hopefuly after thanksgiving BN will have a press release regarding the Nook and the trouble developers have been having with it.
[Barnes & Noble Nook Tablet] shaxs:
I agree... 7" is a little small. Maybe 8 or 8.9 will work. 10" was too large. I wish the gt 8.9 didnt use a tegra 2. That processor kind of sucks for hd video playback.
[Barnes & Noble Nook Tablet] compscure:
They locked this thing down so we wouldn't go to Amazon and Google for apps. They are now seeing blogs, message boards, etc talking about how easy it is to get apps from Amazon on it.

Maybe they won't close the loophole. But I wouldn't bet 250 bucks on it.

I have nothing but respect for anyone who wants to wager on the devs to succeed. I think they will.

But I wouldn't bet a nickel right now that B&N won't screw you over.
[Barnes & Noble Nook Tablet] PaulLeahy:
I don't know, I feel like the 7 inch tablet fills a nice little niche in the market. My phone is mobile, but it isn't really sufficient for all of my web needs; My 10.1 Touchpad (don't judge me...) does everything I need and is certainly more portable than my laptop, but it's not really mobile. I feel like even 8.9 inches starts hitting that same area, too big to just carry with you.

Fair enough. I'm keeping my money on the table, though, we'll see how this thing plays out. Talk about mixed messages from B&N, from the NC to this.
[Barnes & Noble Nook Tablet] antonyfl:
in the EXACT same boat as you. Personally I am only CONSIDERING getting it for the potential for a cheap AOSP ICS tablet.

Hopefully successful workarounds for other locked devices will work. I would donate a pretty penny to whoever can get honeycomb or ICS running on this. I love everything about this tablet and cant find any others that satisfy my wants without spending another $150. So part of those savings could surely go to whoever can allow me to avoid returning this.

Yea I thought it was funny how some people were saying "WHAT!? THIS THING HAS BEEN RELEASED FOR 17 HOURS AND THERE STILL ISN'T ROOT AND CM9/ICS? I'M RETURNING IT!"

I feel really bad for the people that returned the NT for a Kindle Fire. The KF is a flaming turd compared to the NT, rooted or not!
[Barnes & Noble Nook Tablet] acruxksa:
My NT won't even arrive until 11/23 and since I'm at work for another 8 days I won't get to open the package until 11/29.

In the meantime, I just flashed my Atrix 4g (another supposedly locked device) with the latest Fingerprint_CM7_Preview (they finally got the fingerprint scanner working in CM7....yay! ) and Faux 1.45Ghz :eek: OC kernel. That should be enough to tide me over until I get home to my new NT.

Rooting the NT is just further proof that there are some very talented people who frequent this site. I mean if I read the thread correctly, he managed to root the NT while in the store.......probably doesn't even own one. :D
[Barnes & Noble Nook Tablet] Indirect:
I actually rooted it without being in the store. I had to get someone to test it for me after I got the emulator for it successfully rooted but emulator does not mean it WILL work on the device itself so I got lucky I suppose. :)

[Barnes & Noble Nook Tablet] RussianMenace:
Yeah little to nothing has changed regarding the issue in the OP. This thread just turned into a turd-slinging contest and got a bit off track. The original issue still stands as the bootloader IS locked and IS signed.
[Barnes & Noble Nook Tablet] MrOtsKrad:
Ah, the Condescension is strong in this one.

Yes I read it, and yessum I sure does understands it....

....I also have a sense of humor and also do not think just because its got a B&N chastity belt strapped on to it justifies saying

"Don't buy this if you expect any real development to happen on it."

:p

Edit: also, Im a little emotional hearing all these rumors about Farve being Cutlers replacement...leave me alone!
[Barnes & Noble Nook Tablet] acruxksa:
While the boot loader may be locked and signed, it's not the worst news possible. As I alluded to in my earlier post, my Mot. Atrix was in a similar situation at one time and although development for it doesn't move as fast as some of the other devices out there, progress is still being made.

I believe the early posts in this thread had very good information on the nook tablet bootloader and efforts to confirm it was locked, but a less sensational title would have helped avoid many of the "I'm returning my Nook Tablet and you should to" posts.
[Barnes & Noble Nook Tablet] Entropy512:
How is it jumping the gun? Do you have some evidence we don't that the bootloader is unlocked and not enforcing signing and pokey just screwed up? You have not provided any such evidence.

If you're referring to the fact that root exists - root's kinda nice but it's not that big of a deal, especially on a device like this where achieving its true potential requires major firmware modifications.

Even if the kexec() hole still exists (Easy enough to close in the defconfig - I'm shocked Moto left it open), just look at the Droid 3 or Droid X2 forums to see what happens to development on a device when you can't directly boot custom kernels.
[Barnes & Noble Nook Tablet] NickBoy98:
hey... just a quick thought?

as a complete noob as far as android development goes (tried to root my friends phone... didn't work out so well)

I suggest you try to follow one of the following noob methods...

Purposely break/brick your nook tablet so that you will have to take it instore to fix... if you have a watchful eye you may be able to see if the repair man/employee presses a certain key combination to access a special menu? boot menu? if they use a repair sd card?

or befriend a barnes and noble nook specialist and get them to tell you all their secrets about the nook

hope i helped XD

*chuckles cause i probably didnt help at all*
[Barnes & Noble Nook Tablet] deserthi:
I was watching at B&N when they did this. Not even hooked to a computer. Thy have microSD card they put in the tablet and have it reformat and restore it. That's it. I tried to see if I could steal it but they had a watchful eye on me.
[Barnes & Noble Nook Tablet] PlacidCat:
Doesn't surprise me - probably have an image that is properly signed. The issue appears not that the system can't boot off SD but that you need an image with the proper signature. I think this was mentioned early in this thread.

So, hack the key(s) or wait for someone to leak them...?

Take this with a grain of salt - simply writing my interpretations of prior posts.
[Barnes & Noble Nook Tablet] rmm200:
I still find this whole topic misleading.

There is no "Bad News".

There is no "Worse News".

There is just news, and there is new news daily.

Thanks to the hard work of the devs, we have a very useable tablet at this point, and by far the best value for the dollar I have seen.

Master, your vision. Your vision was right! Tai-Lung has broken out of prison! He's on his way!
[Barnes & Noble Nook Tablet] Entropy512:
No... It's NOT that simple. To try and simplify:

The CPU itself is configured in an irreversible manner (blown eFuses) to only boot software that originates from Barnes and Noble. Any bootloader/kernel on this device must be digitally signed by Barnes and Noble. These signing keys are closely guarded secrets - it is EXTREMELY rare for them to get leaked out or reverse engineered. For example, in the case of the PS3, it required multiple hardware compromises followed by Sony screwing up and not using a random number when they should have.

So far I have not seen a single instance of anyone cracking the OMAP4's code signature enforcement.

Some Motorola devices could be worked around using a technique called kexec - but there's a good chance B&N learned from Moto's mistake here and disabled that feature.
[Barnes & Noble Nook Tablet] hololight:
Now I see it will not boot from SD without proper signature ... but I didn't notice if anyone has said if it will boot unsigned code from emmc?

I don't know why you would implement checks on SD and USB but not emmc... but figured I would ask...

More bad news - Assuming that android_4430BN_defconfig in the B&N source drop is the defconfig they used:

#
# Boot options
#
CONFIG_ZBOOT_ROM_TEXT=0x0
CONFIG_ZBOOT_ROM_BSS=0x0
CONFIG_CMDLINE="root=/dev/ram0 rw mem=128M console=ttyS2,115200n8 initrd=0x81600000,20M ramdisk_size=20480"
# CONFIG_CMDLINE_FORCE is not set
# CONFIG_XIP_KERNEL is not set
# CONFIG_KEXEC is not set

That's the final nail in the coffin - locked bootloader plus no kexec = really bad

Good News: Development will continue

Bad News: It will be SLOW

If you bought this with hopes of installing CM7 within a month or two, or installing CM9 ever, I think you will be disappointed.

If you bought this with hopes of using it rooted with some slight workarounds to get the apps that you want, you should be very happy.

It is a great value for the hardware, and it is just sad that B&N went in this direction. I can see why they did it (revenue in their market), and I don't know if it will hurt sales or not (% of total units sold vs. % sold to xda readers).

Not sure what I am going to do with mine right now, but I will keep it for some time longer and pray that one of two things happens.

1. B&N decides to unlock the device (unlikely unless broad public outcry)

2. Genius Devs figure out something different than the two currently known ways to get around signed bootloaders.
[Barnes & Noble Nook Tablet] anlog:
I suspect that a rooted Nook Tablet will be fine for +80% of the community of people that actually root their devices. Even if the bootloader never gets unlocked, I'm fine with mine the way it is. The speed of the stock UI/kernel is more than enough for what I use the tab for.

I also suspect that we will have an unlocked/bypassed bootloader MUCH MUCH sooner than two months. The Nook Tablet has been out for 3-4 days and we have already made quite a bit of progress.
[Barnes & Noble Nook Tablet] Entropy512:
That's an SBK key used to flash via nvflash - the device never enforced signed binaries for booting anyway. A manufacturer has very little to lose by the nvflash SBK key getting leaked - as evidenced by how lazy Samsung was about locking locking with an SBK on Galaxy Tab 10.1s (around 50% of devices initially sold didn't even have a lock.)

Private signing keys used to sign binaries for bootloaders that enforce signed code are MUCH longer than that and MUCH more carefully guarded.

To put it another way - because the negative impacts for a manufacturer of an nvflash SBK leaking are FAR less than the private key used to sign code leaking, an employee of a company is going to be FAR less fearful of repercussions/far less careful about handling said key. Hell, that SBK might have even been leaked intentionally in order to reduce warranty claims. (Locking out APX flashing mode on a wifi-only device is, in my opinion, stupid, as it doesn't benefit anyone and makes it easier to brick a device.)
