[BOUNTY] $$$ to unsign a signed bootloader!

[rmanaudio]

UPDATE: APP/Patch released here: http://xdaforums.com/showthread.php?t=888071

I am starting a bounty for the coders to find a way to unsign/unlock a signed/locked bootloader!

We all know that new JMx firmwares will load a new bootloader and lock it up... if any coder can reverse it and unsign it so we can flash customize kernals and ROM...he or she should get paid!

I will start the bounty with $10.

rmanaudio: £10
alterbridge86: $10
iuzar: £10
deezid: $10
retroqwe: £10 = $15

Im not sure if i understand it wrong, but as i understand the sbl is doing all the flash work, and boot check the signature. correct me if im worng.

So patching the sbl would be a good idea, so it dont check the signature of patch it so it will always end up with pass signature.

It may not help people with all things signed, but most with sbl unsigned will be able to flash an unsigned boot and zimage.

Another way is to see if any og the G2 spl flash is possible on galaxy tab.

I assume that most people with signed bootloader will have SBL signed too cus they come together in a rom packet.

[rmanaudio]

check here

How does that fix the problem? Those ROM's are good for people who dont have signed bootloaders!

Once you make the mistake of loading signed...you cant go back!

 

[GOF007]

Yeah ROTO's ROM is great!!

And yes, signed bootloader and sbl still able to flash those firmwares.
I have both signed BL and SBL and yet I go back and forth many firmwares with no problem.
So it is not so big deal to have signed BL and SBL now, as long as there is no really great kernel released yet.

We just cant flash new bootloader and kelnel = =

And yet I +1 for the idea of the Bounty ^^
Be able to get unsigned BL and SBL back will make me feel safer ^^

Yes...we can flash any JM* firmware that ROTO makes because those firmwares are signed firmwares and our bootloader will except them....so can someone without signed bootloaders as their bootloader doesnt care of it is signed or not.

BUT...lets say some new JK or JL or something else new comes out that is not signed...or lets say CM 6.1 or CM 7 gets ported soon to the tab....we will not be able to load those....or even a kernal with voodoo or OC.

Please state how much you want to add to the bounty...thanks.

I unfortunately was hasty and ended up with a signed bootloader...so count me in for $10!

 

[iuzar]

count me in for $10

 

[deezid]

10 $

£10 here as well.

 

[lux209]

count on me for 10$ as well

 

[rmanaudio]

Thanks for all the support guys...keep them coming!

I think if we get enough money we will get the attention needed for the coders to look deep into fixing this issue.

We really need this fix for the future...as I have a feeling CM 6/7 mod or gingerbread port is coming soon for the tab.

You need to think bigger, $10 milion and build an RSA-1024 cracker with $10M array of FPGAs. Then maybe after 1000 years you will get the key.

Thats not a very nice post!

Maybe if it cannot be removed, it can be disabled (the bootloader check) or maybe a way to sign customized kernals and ROMs!

No problem! I have a Lifetime warranty on my Euro Tab and my name is Norris. Chuck Norris.

 

[lux209]

I think that the solution will be to find a way to bypass the signature check. And not to crack the encryption.

 

[Alcibiade]

Lost cause probably...

what is the encryption exactly? it sure ain't 1KiB.

Has anyone talked to, or have contact with, the Koreans? If there is a cracking vector, to goes through South Korea.
