How to Unlock Sony Ericsson k790 - GSM-Forum

rushwhq · 10-20-2006, 00:13

Hi All,

Anyone got this model ?

I tried unlock/flash with UB Box and i got this error message:
Terminated with error: No patch for this CID/Color, you should use testpoint (00024530)

I didnt find testpoing image.

Edited:
Ticked just smartcard but still get the same error

Cheers

Hi!

K790 is a DB2020 model.
So you can't lock/unlock, change IMEI, and save/restore GDFS image.
You can only use flashing, and GDFS maintenance, and you always have to use smartcard.

Ok,

Them, when will be available direct unlock ?

Cheers

NO UNLOCK for db2020 for now with any box... only if yu have EMMA III....

fonec · 11-29-2006, 12:42

Bullsh** Emma 3 cant unlock anything.
That is just a urban legend.
Emma 3 is the support tool used by sonyericsson servicecenter
to upgrade and repaire software and it cant unlock anything
cos a servicecenter are not promited to unlock cellphones.
They can only repair them. Only the provider have the code to unlock.
But they can on the other hand not unbrand them.....

Just for your inform:for unlock you need

1. EMMA III GSP login
2.CSCA SmartCard
3.SE dongle

about from dongle see the attachted image

about from emma:

EMMA = Service software/solution by SE themselves. Protected by the EMMA smartcard to prevent non-licensed usage. Current version is EMMA3, though EMMA2 is still alive (but kinda useless on newer phones). The EMMA smartcard contains an algorithm that allows EMMA to communicate directly to/with the phones CID, so performing operations the way they were intended. The smartcard and its algorithm has not been cracked. Current EMMA access levels exists:Service Update - Can't unlock phones.Service Update Pro - Can't unlock phones.Network Operator - Can't unlock phones (but sure as hell can lock them ).Service Center Std - Can't unlock phones.Service Center Rc - Can unlock phones, as they have a special version of the smartcard with a CSCA key.Research & Development - Can unlock phones, as they have a special version of the smartcard with a CSCA key.

about from db2020 etc:

DB2000, DB2010, DB2020 = SEMC (Sony Ericsson Mobile Communications) hardware platforms. It's something similar to chipset in PC.DB2000 (another name is Marita) is a GSM+3G(UMTS) capable platform, SE K600/K608/V600/Z800/W900, Sharp 802sh, 902sh, 903sh and LG 3G phones are based on it.DB2010/2012 (Marita compact) is GSM-only, non-3G, platform. Most not very old and modern SE phones like K300,K500,K700,K750,S700,W300,W550,W800,Z520,Z530 are based on this chipset.DB2020 is the newest product of SEMC. K800, K790, K610, Z710 etc, Sharp 904sh feature this most secure (from SE's point of view) platform.

DB2020 stands for Digital Baseband 2020. It's the next generation baseband "processor" from SE. It incorporates new security measures, so the old method of breaking into DB2000/DB2010/DB2012 (it's predecessors) is useless against it.

Now, later SE security is/was actually very strong and therefore hard to break. It's RSA-based, meaning that it's based on public and private certificates and keys. These two are calculated based on huge prime numbers that cannot be "reversed", meaning that there is no way to calculate the private key based on the public key nor vice versa. Anything encrypted with the public key can be decrypted using the private key. The two "peers" share their public keys allowing them to decrypt eachothers "messages". For more information on RSA, please consult "http://en.wikipedia.org/wiki/Rsa".

As far as I've gathered, the "loaders" (programs) used by SE to communicate with phones either on the production line or at service centers are "signed" using a similar system (again, consult Wikipedia). An initial communication channel has to be set up, then a loader must be sent to the phone. It is through this loader that operations take place. E.g. if you want to flash a phone, you send a loader to it, this loader then listens for a flashfile to be transmitted and writes it to the memory.

Previous ways of breaking into SE phones were based on vulnerabilities in these loaders, somehow allowing developers to make them perform their own operations instead of their original intention. Unlocking for instance, requires a hard-to-get access level and smartcard (holding the CSCA key, allowing a new security zone to be written and signed) for SE's own service solution, called EMMA (now counting version 3/III). Cloning this smartcard or getting the CSCA key out of it has yet to be done, if it is at all possible, the key never leaves the smartcard, calculations are made by the card itself (smartcards are very advanced, some hold 200Mhz processors, for example your average satellite-TV card).The card also holds the algorithm/mechanism for challenge/response authentication with the phone.

DB2020 is completely rewritten from scratch, I gather. They have been thinking "security" all the way through it's development as opposed to the apparent make-shift solutions found in earlier versions. This calls for new tactics by "SE-tool" developers.

What´s the different what i just told?
DB2020 is at the moment IMPOSIBLE to unlock.
Any program or box or Emma3 or what ewer.
The smart one comming up with a sulution
will be a millionere within a month.
Same as bb5 and the other urban legend, "dejan box"
That is not exist, only people talking about it.
No one seen it so far.
I have acces to emma 3, just to inform. It cant unlock ****....

shaaker · 11-29-2006, 21:26

some serbian and other guy has it

About from dejan box also not legend,bb5 unlock is true and aviable

SEMC DB2020 is very secure platform: using of RSA, SC, SEMC Server... till today similar (paranoid protection ?!?) is not known on GSM world.
Its evidence that SEMC are invest much money to educated people with good experience (some Hacker also

) to build good protection.

Our congratulation.

But, SEMC are give unlock possibility, shaaker wrote what all is needed to unlock SEMC DB2020 phones.
BUT (again) its evidence that one bug is not solved - distribution of dongles

thanks for that move.

The diference is that Nokia phones cant be unlocked via SALO server ASK/RPL but SEMC can by, their own server.
For us are also interested why they make good protection and give unlcock available on another side
