Dear: A few weeks ago I bought a Samsung i9000 S Galaxy, with the function "unlock pattern" working.
A few days ago a co-worker playing with my phone, tried several times to unlock it by entering the wrong pattern, which occasions that the phone will block indefinitely. As an option to unlock it you need to enter valid user name and password associated with your phone's Gmail, it is there that begins my big headache. I tried entering my username and password which was associated with the phone but told me that the data was incorrect, I clarify that I have configured, enabled and operating a 3G data connection but I could not make it work. I read countless posts where indicated a number of possible solutions, from testing with password "null", try without the "@ gmail", try "@ googlemail.com", etc, but without success. I also tried typing the hidden codes of hard-reset, but do not work because it only allows emergency calls. Obviously I tried turning off the phone, start in recovery mode with all possible combinations of buttons and even tried to flash the rom connecting the phone via usb cable and try to start it in "download mode" but the combinations of buttons do not respond, the phone starts without stopping. You say I have had not enabled the "USB debugging mode". As indicated in this post http://code.google.com/p/android/issues/detail?id=3006 the problem that I cannot unlock the phone through my GMail account is due to a bug of the Android Operating System. I contacted the seller and told me he has a phone like mine with the same problem and have given no solution yet, I also got in touch with the support of Samsung, which I am still waiting for a response. Clearly this problem is due to an operating system failure, if you also added the keylock that comes from factory to enter in "recovery mode", "download mode", etc. It is a very complicated situation with the phone because I tried everything with no luck. The number of people affected with this problem is growing and still there is no solution from Samsung and Android. I thought the Galaxy was a phone i9000 S without problems, but clearly I was mistaken.
After much fighting with the local Service Samsung in Uruguay, in the Call Center in Argentina and Spain, all we received were automatic responses to emails sent to Samsung with this reply "You should contact the local Service Center, the only solution left was to find a solution on my own. I would emphasize that Samsung service is very bad
1) I put my SIM card
2) I called from another phone and answered the call
2) Press the touch button that is on the left winged “home” button
3) There appears a menu with 3 options, "Contacts", "Notes" and "SIM services”
4) I selected "SIM services" and lower the drop-down menu at the top.
5) Press the home button (the square in the middle), I went to the main menu, Settings, Privacy and data factory reset.
I lost all installed applications and some data but I got my phone back, hope you find it useful.
Besides the problem of not being able to unlock the phone to my GMail account due to a bug in the operating system is also a security problem being able to access the menu while the phone is locked. Imagine this situation, if someone tried to steal the phone and try to access the critical information it contains, even though it has the pattern blocking enabled, using the solution provided you could access the contents of the phone even when it is locked for security, the thief could obtain critical information from the company that you work. Really unfortunate.
