Bypass pattern lock on Sony Xperia Z2 and backup all data

So in a nutshell the suggested solution is "press several times buttons at random and before or later you will by-pass the lock"? ?

Or that you have to take a picture (i.e. out of all the "random" presses, taking the picture is what unlocked the transfer)?

That is very interesting and I wish my Chinese was a good as your English is. Are there equivalent words in Chinese to English for forensic terms? It would not surprise me if you are a leader in forensics in the Chinese market so perhaps you had to create new Chinese language forensic terms. What are the characters you use for computer forensics, please.

So, it appears you have found a glitch in Sony's phone to PC authorization/handshake system.

Perhaps the combination of the desktop software suite installation plus your actual use of the phone - taking pictures - was sufficient to convince the PC software suite that you are in fact the phone owner.

** Was the phone connected by USB cable to the PC running the Sony suite at the same time you took a photograph and thus got the PC to "trust" the phone (enough to export some level of owner-personal data)?

It makes sense if, for example, a Sony phone owner did legitimately forget their pass code. It would be a heartless Sony who did not at least allow such a forgetful phone owner the ability to extract out some level of personal data stored on the phone, which then one could import into a new phone that Sony just sold you "We cannot retrieve your forgotten unlock code, but we can sell you a new phone"?

Do you think the Sony PC Suite stores the phone's passcodes and other passwords? I wonder if the Sony PC Suite was unable to extract the phone's "lock code", and thus showed you the screen lock message, or if the PC Suite did actually ingest the phone's passwords but wanted to make sure you are the actual owner.

Thank you guys. As long as you could achieve your purpose, the easier the better. So if I could backup the data from Sony Xperia with pattern lock on, I don't mind pressing buttons or taking photos or make emergency calls whatever.

Sorry my Sony PC companion suite is Chinese edition, and I have no time to take screenshots for English version…Actually I use English version software but you know that some students are not familiar with English, just like "UnallocatedClusters" is not familiar with Chinese.

Yes I took photos when Sony Xperia connectd to my workstaion by USB cable. Suddenly I won't need to establish the "Trust" relations between my workstation and Sony Xperia Z2 and I could do the backup successfully. We should take advantage of this when it comes to Sony Xperia phones extraction.

I just want to let you know that if I found something interesting helpful to forensic guys, and I will let you know ASAP. I think Sony does not care about users lost or forgot his/her passcode/pattern lock, and the only way to take ownership of phones is to unlock bootloader first. The consequence is that he/she will lost all data. I will try to find ways to unlock Sony Xerpia bootloader without data loss,but not now, maybe couple days later.

gorvq7222,

Thanks for sharing this.

Be careful, unlocking the boot loader of a Sony device always triggers a reset of all data!

gorvq7222,

Are there forensic software applications that are native to the Chinese market?

I actually can read many Chinese characters as I can read, write and speak Japanese fluently.

Unfortunately, there is no direct translation for the word "forensic" in Japanese, so the best translation is "フォレンジック", which is Katakana, not Kanji (Chinese characters).

In Japan, most companies never want to be involved in litigation, so there is very little software in Japan.

I am curious what your perspective of the Chinese domestic market for digital forensics is?

Thank you guys. I don't have to unlock bootloader first. I just use Sony PC Companion to bypass unlock warning and backup all data from a Sony Z2 D6503 with pattern lock on. Is it amazing, right?

As to the word "forensic", in Traditional Chinese is "鑑識", and in Simplified Chinese is "取证". I do know some forensic software that are native to Chinese market, and one of them is InfoDetector. You guys could try to get a trial for test.

Usually we usually use forensic software like X-Ways, EnCase, FTK. BEC, IEF, etc. As to mobile forensic, we use Oxygen Forensic, XRY, UFED, etc. Everybody heard about those forensic software. So we don't have to explain to judges that why we use that forensic software.

The Chinese domestic market is very big due to more and more computer and cyber crimes. Not all forensic guys here could read/write English very well, so they hope got better Chinese character support from those famous forensic software. Not just user interface, the most important is that those forensic software could recognize and decode Traditional/Simplified Chinese character well.
