[HD2 Android Q&A, Help & Troubleshooting and Genera] linstit:
Hello everyone,

It's been a while that i'm using android on my hd2, and i saw a really nice game on my friend's android phone called Asphalt 5, however, i downloaded it and installed it n it worked so well for me, but the problem is, sometimes when i open the game it comes with no sound and when i want to turn up media volume it doesn't let me do that and the media volume is stuck at mute, but some times it works and the sound comes too, and after that the media sound stays in mute and doesn't come up it's not only inside the game, after i exit the game, i can't listen to music or have media sound again and for having it i have to restart phone and boot android again,

can somebody tell me whats the problem with it ?

:confused:

I have a Orange SPV M2000 with WM2003 version 1.31 (sim unlocked) and would like to upgrade it to WM6.5 for better browsing properties. However, when I tried to upgrade it from the below link:

http://xdaforums.com/showthread.php?t=758462

It didn't work for me, as the updater didn't detect my device at all. Note that I am using Win XP SP3 and followed everything in the feedback from other users. Are there any other alternative ways to do it?

Also, I have lost the installation disk so I don't have the software to sync (not that I have valued information inside anyway).

Many thanks!

it was not productive

so it just evaporated, we lost a good chance to do real good and get some cool phones out, all because the people couldn't behave themselves

Hello I'm writing this behalf of the cracker.

I am pleased to announce an exciting news. I believe we have solved Motorola RSA bootloader by cracking its sign tool. Thus, custom kernel can be built. The cracker wants to work with a developer who knows kernel/rom building. Making long story short, like porting cyanogenmod is possible

Please contact me as there will be a lot of casual replies in the bottom.

Contact Information : urdestny@gmail.com

Please do not send email if you are not an experienced developer.

This will also solve all motorola's smartphone and is applicable throughout its line-up.

Thank you Cracker and others who made this dream come true :)
[Defy General] ericlaw02:
Agreed, more technical details would be nice.

And I'm just wondering, why wouldn't the cracker release the tool/method itself, and instead ask for collaboration with other developers?
[Defy General] noxunas:
Please, put this thread in the developpement section !
[Defy General] ggnx190:

[Defy General] urdestny:
He will give you guys more details. It's a lot of work for one man to handle, therefore, requires other enthusiasts who can collaborate.

I can also tell you that those of you who thinks that it is too good to be true, well, I am pretty confident that he knows what he is doing. He actually made some changes to exisiting rom for Korean users. He can't speak English well, so I will be his proxy.

We will release more details, and once I get up my post up to 10, I will officially start a new thread in the development corner.

[Defy General] urdestny:
Being skeptic is your prerogative. However, in which thread did I ask for an email address? I said contact me individually if you are serious. And, I said I will start a new post on the dev corner today. I'm waiting for the hacker's email too.

[Defy General] racca:
this might be it
[Defy General] ketonkss4:
Im excited but I dont know why!

Does this give our defy's like endless possibilities?

...and does the commoner without the blessings of dev-powers really benefit from this tool? Or do we just just wait for devs to come up with something?
[Defy General] urdestny:
I'm afraid it is the latter. I've seen the first half of his secret. He is explaining how things are done , which partition has the sign key info and which has public key information. Basically, it is an idea how to bypass the private key which people are trying to crack.

Anyway give him couple more hours. I have the first half of his article. When I get the final half, I will start translate the whole article.
[Defy General] racca:
in korean? do you mind posting the original article first?

things might got lost in translation (and we might need to do it twice),

it's much better if we had the original as a secondary source (and translate

it to other languages if needed).
[Defy General] urdestny:
I can't copy/paste the original article. It wont let me drag it because the site is protected. I dont think anyone can translate Korean into English here. I have to wait until he sends me an email which he told me he will do when the article is finished.

But if you want to know the original link (though you wont able to view it) its here:

http://cafe.naver.com/androiders.cafe?iframe_url=/ArticleRead.nhn?articleid=801614&

Ok. i found away, how to view this page.

http://search.naver.com/search.nave...rsa+signature+bypass&x=0&y=0&sm=top_hty&fbm=1

Click on the page above, and click on the thred

Motorla RSA Signature Bypass tool

However, the first half of his article says, you must understand the basics to follow his methods. Those links are

http://en.wikipedia.org/wiki/Public-key_cryptography

http://en.wikipedia.org/wiki/RSA

http://en.wikipedia.org/wiki/Digital_signature

https://www.droid-developers.org/wiki/BootRecoverySignature

It's lunch hour in Korea. I promise that I will share the article in couple hours.
[Defy General] youlsa:
It's not gonna happen.

Many Korean geeks are watching this thread, so don't worry.

If something goes wrong, somebody will correct it. ;)

Actually, second article is not online now.
[Defy General] bschuele:
much ado about nothing??

i hope this motorola_rsa_sign.rb is not the bypass tool!!

if you look at the end of the code:

1. first he make a new RSA key pair (pub and private)

cert = OpenSSL::PKey::RSA.new(1024)

2. he takes the pub part of the key

public_key = cert.public_key

3. he overwrite the pub key with the motorola pub key

public_key.n = hex2dec(motorola_public_key)

4. he check with the public key

puts public_key.verify('sha1', sign, content)

Conclusion: with step 3 he just overwrite the public key and makes step 1 and 2 useless.

Or with other word, the private key of step 1 does not match the motorola's one.

That's not how RSA work, you need the PRIVATE key to sign!!!!

And of course this key has motorola....
[Defy General] switchgott:
Hi, but what does it meen?

How we can create a new rom and sign it with the key??
[Defy General] bschuele:
if that is it, we can't because you need the PRIVATE key to sign.
[Defy General] switchgott:
So all is useless!

So IT Koera make a big job, but we cant use it for motorola devices :-((

No hope :-((

But on other side, why they tell us this?

I hope they have test it befor posting !

So it could be, thats correct and it work!
[Defy General] youlsa:
Last part of original article is as follows

=====================================

이제 상상을 해보죠..

RSA Sign을 하려면 개인키로 한다..

우리에겐 개인키가 없다..

부트로더는 Sign을 검증한다..

RSA Sign을 검증하려면 공개키로 한다..

공개키로 한다..

공개키?

공개키는 파티션에 들어있고.. RSA Sign값도 들어있다..

부트로더는 파티션에서 공개키를 읽어와 Sign을 검증한다..

자.. 그럼 우리가 RSA 개인키를 만들고 컨텐츠 Sign을 해서 파티션에

나의 공개키와 Sign값 넣어놓으면 부트로더는 내 공개키로 Sign값을 검증할것이다..

결론

====

RSA 1024bit 개인키를 생성한다.. (2048bit 이든)

그 개인키로 컨텐츠를 Sign 하여

해당 파티션에 공개키값과 Sign값을 바꿔치기 한다..

자.. 쉽죠?
[Defy General] ABC_Universal:
Be patient, guys! Give some time and see what comes up. ;)
[Defy General] youlsa:
Translation goes like this... (I don't know whether it's right or not... Just translated)

=================

Now look...

We should use PRIVATE KEY to rsa-sign.

We don't have PRIVATE KEY.

Boot loader verifies RSA Sign with PUBLIC KEY.

PUBLIC KEY...?

PUBLIC KEY...

PUBLIC KEY is located in the partition. We know where it is. So is RSA sign value.

Boot loader scans the partition to get PUBLIC KEY, and verify RSA Sign with that PUBLIC KEY.

Now! We can sign our contents with my PRIVATE KEY.

and put PUBLIC KEY(MY KEY!) and Sign value to the partition.

Now Boot loader will verify the Sign value in partition with "MY" PUBLIC KEY.

Conclusion

====

Create Private Key (1024bit or whatever)

Sign the contents with that private key.

Put public key and Sign value in the partition.

Easy. Eh?
[Defy General] dogo2:
Well this sounds plausible... With no way to verify the public key you should be able to use whatever key you want. On the other side you have to get youre phone on and connect to internet. What happens then is unknown :rolleyes:
[Defy General] wods:
Public-key can be modified easily?

Is there any kind of protection?:confused:
[Defy General] bschuele:
No it is not.....

I'm sure the motorola key's are also signed by a CA-root certificate (http://en.wikipedia.org/wiki/Root_certificate)

And you cant use a self Self-signed one. (http://en.wikipedia.org/wiki/Self-signed_certificate)

And the boot loader check's if the pub key is signed by a root-CA....

Else the would be to easy.......

Yes! You can verify Motorola's encrypted content with Motorola's public key.

But you CANNOT verify your own signed encrypted content with Moto's public key!

If you want verify your own signed encrypted content, You must use your public key!

[Defy General] shawnsdada:
To be completely honest, I thought the sbf leak for the Xoom was intentional. They announce it has to be set back to factory settings in order to get the 4G hardware upgrade. Then what do you know? The sbf leaks out not long afterwards making that process a lot easier for some people. Could be completely wrong.

Any chance this method has anything to do with postings made by Eugene_373 on Twitter just a few hours ago? Announcing that he flashed an update.zip on the Defy without breaking encryption on /system or is this all unrelated?
[Defy General] IFLPI:
so, can the author verify is it bull**** or really BL is hacked?

Personally I don't believe in such mysterious crackers

Well, I have GE installed in the N1 and in the Galaxy Tab, this one has internal memory, even if I not use a sd card I can see the "sd card" in the file explorer, something like if where a virtual disk.

Must I have my devices rooted to have a look if find something on the preferences system or data/data? Hope any guy with knowledge here find this issue interesting enough to have a look, maybe its a simple thing to change but I have no idea how to look for.
[Android Software/Hacking General [Developers Only]] snakerdlk:
You can try to unpack the apk file for the google earth app and check if any of the files there has any mention of the size limit.

I think it is better than to go hunting for the configuration files spread all over your phone.
[Android Software/Hacking General [Developers Only]] lagoausente:
Have unpacked the apk, open with notepad, there are characters unreadeable and some text. On the text have found references to the "clear cache" , that refer to that option on the app, but no specific. Only this:

buttonView c cacheDir cal

callbackProxy canWrite cancel cause cb cel

What I think doesn´t mean anything. I guess..., maybe 200mb is the default cache that Android allows for any app considering that the the most often devices a mobiles phones with limited space and or performance?
[Android Software/Hacking General [Developers Only]] Ogrisor:
You see all those funny characters because the app is compiled.

You should try decompiling it. I would post a link for you , but I'm new and can't post links , so just search on google the word : smali.
