DB2020 flashing difficulty level

[slappy]

@cruiser team
i'm not talking about unlocking, just flashing for firmware upgrade/downgrade which probably will be available for public at official sony ericsson website. what is the estimated difficulty level? that should reflects estimated time for this solution to be released in cruiser.

thanks.

sloppy, I totally agree with you! How difficult can it really be to support DB2020

@Cruiser team, any progress updates (general or specific)...

If it is so easy, why does no one have a current solution for it? Why have you not released a solution for it? Nothing is hard if you know how to do it. Problem is to get there!

Read this article. Please post here any obvious weaknesses you can see, so that Lead/the_laser/Saras etc can use them. How difficult can it really be?

Basically all current RSA bypasses have relied on holes/exploits in the loaders. With each CID increase, the holes have been closed up. DB2020 is as I understand it nearly "holeproof"

So, to answer your question: F*cking difficult.

Slappy's original Q was about flashing and not unlocking. Is Cruiser flashing also out of the question for DB2020 products?

As not too many people have their hands on DB2020 phonez, with loaders and tools, it's difficult to judge how much improvements (or rather to say loop hole closures) there has been. Maybe it's time to think "outside the box" ...

Valid point. Sometimes I forget to read the whole thread properly and go shooting my big ***** off. This is one such time, please accept my apologies.

Having said that, to flash RawFS of all current ARM RSA protected phones with CID > 29 it's necessary to either a) Convert to brown or b) Unlock RSA. Both of these functions require some loophole finding.

The reason that the SEUS service works is because it's plugged into an offical SE EMMA service device - Cruiser being standalone doesn't have that luxury.

So while I was a bit of a tool in my original post, I think the point still stands that it's going to be very difficult. But Lead's already posted the reason for no Cruiser update in a while is because he's reworking the code to support DB2020 phones, so we might all be in for a nice surprise.

About difference between DB2000/DB2010 vs DB2020. It's my understanding from talking to various people that in the DB2000/DB2010 RSA security isn't used "properly", while in DB2020 it is.

Apology accepted!

Let's all hope that there will be some nice surprises for the DB2020 products with the next Cruiser version! Could we even expect it to be version 10.00 as it would be a major break-through to take care of DB2020...

BTW, why is it almost always Bob and Alice that sends messages to each other?

[slappy]

hehe.. lets wait for cruiser team then.

[crow2k4]

804sh is DB2020? files and TP is under test..

Great, but tests by whom?

[slappy]

i was about to ask the same question...

[m_dige]

Perhaps Lead has allready cracked the CID 49 DB2020 etc. but is now working on a new protection for cruiser. A if they were - who could blaim cruiser team for that.

With the laser and Zulea waiting for a solution (since they canøt do it themselves) it would seem a smart move to me.

But that's just a thought.

Best regards

i hope he protects it well, so that we have it for atleats a week or two, or even better that other devleopers are forced to find their own solution.

[charlieneoh]

what is it mean DB20xx ?? where should i go 2 surf 4 the detail ?? how 2 master it ??

[Zwed888]

DB is for digital baseband and number is chip version. Higher number better chip. DB is phonez "brain" with CPU etc...

Ask Lead how to master the chipz
