How to remove Android phone pattern without losing any data!
What is needed; phone w/ sdcard slot and sdcard.
1. download update.zip (http://d-h.st/i0e) and put it in sdcard root.
2. boot your device to recovery menu (common combination: press volume up+menu+power)
You should see "apply update.zip from sdcard"
3. select it w/ menukey and you should be done!
4. exit and reboot!
If this doesnt work, you can use failsafe method!
1. download aroma filemanager from here (http://goo.gl/mrKhW7)
2. rename it to update.zip and move it to sdcard root.
3. see step 2. on first plan
4. go to /data/system/ and delete gesture.key and password.key
5. exit and reboot!
Notes;
If your phone doesnt have sdcard slot ( or you dont have card) you might need to install CWM recovery to use usb mount and move files.
I prefer failsafe method but its more risky because you can delete any files on your phone and brick it.
Enjoy!
