Encrypted bootloader?

Actually, regression is very rare when it comes to things like the bootloader that is actively being developed and tested. Like I said earlier, you'd have a better chance of attacking the baseband.

Sorry, I don't exactly see how baseband attack could help - and what to attack in the first place. Baseband processor core is completely separate and isolated - only data transmitted back & forth between baseband CPU and application CPU. And how in the world a hacked baseband could influence the signature checks during boot process?

Hey, I was wondering something. Now I dont really have any experience with hacking phones and finding sploitz. But, is it not possible to bruteforce through the code on the stock rom to find the key and then just inject it into a custom rom? I imagine its not, so that brings me to my next question, how come?

Take a look at the s-off hack we'll be releasing in a few days and then ask yourself the same question.

The radio has a much larger part in enforcing security than the bootloader does.

Ah, so that means that RIL's and AT interpreters obviously cannot exist.

Excuse me for my ignorance, but does this mean you have cracked/made progress on the bootloader/custom roms?!?! Sorry if im jumping the gun...i just want my cyanogenmod!

Sorry, no. Its for the current generation of HTC devices. I'm waiting for my X to be shipped.

Ahh darn. Any chance of implementing that method on the X?

Is there anyone actually working on the bootloader? Is there any progress at all?

There's really no such thing as progress on something like this; its either done or it's not.

Wait, are you definitely speaking about Motorola secure boot platform here? This just didn't sound quite right.

Ha speed+eris in one sentence? That's funny... What's it like having a tiny, discontinued phone?

and why would you post from such a phone in the X forum?

Can you speculate on whether a potential Droid X crack will be applicable to the upcoming Droid 2? Or is that impossible to tell at this point. I ask because it seems the dev support will be much greater on the DX than the D2.

Birdman (mrweeeedbirdman on twitter) said the exploit is patched in froyo. So if the d2 is shipping with froyo i would guess the exploit will not work.

Right, but we're talking about the bootloader here. I'm wondering if all of this effort that will be put toward cracking the bootloader or achieving 2nd boot on the Droid X will be applicable to the Droid 2. Since it's likely far fewer devs will be working on that device, any crack will likely have to come from the progress made on the DX or Milestone.

^^ lol exactly. Customize your little Eris all you want...it's just putting lipstick on a pig. I don't care what you say..no customized eris can even compare to an all-stock X...just sayin'. And then once we get custom roms on the X we'll see who is really laughing...or lagging in your case, with your cute little 528mhz processor.

a 2048 bit key has 2^2048 possible combonations or 3.2317*10^616 or:

32317006071311007300714876688669951960444102669715484032130345427524655138867890893197201411522913463688717960921898019494119559150490921095088152386448283120630877367300996091750197750389652106796057638384067568276792218642619756161838094338476170470581645852036305042887575891541065808607552399123930385521914333389668342420684974786564569494856176035326322058077805659331026192708460314150258592864177116725943603718461857357598351152301645904403697613233287231227125684710820209725157101726931323469678542580656697935045997268352998638215525166389437335543602135433229604645318478604952148193555853611059596230656 combonations

This is, of course, an oversimplification of the issue - but as you can see there are a great deal of possible combonations making a brute force attack quite unreasonable.

eris easily overclocks to 768, some to 825, still no where near the power of the ti omap's

I am an incredible owner with trade in options, however i have an eris in a drawer that is still a very nice device. My eris ran stable at 810mhz and was rocking Froyo. I am just saying don't pick on the phone that never claimed to be anything better than the best 100 dollar phone you could get at release.

Not dissing but when someone comes in the X dev forum to brag about his eris it's kinda pathetic...
