volcano box reset pattern lock without usb debug

Source: Not really a source but got a hint from a comment under this answer. This is how it actually worked out when tested on my devices. Unmount Data and reboot into Android OS.That delete ( rm) command is not necessary since adb push should overwrite the file, but I executed it for my peace of mind. Rm /data/data//databases/settings.dbĪdb push ~/settings.db /data/data//databases/ Save the changes in settings.db and copy it back into Android by typing: adb shell These checks in step 6 and 7 are not necessary but should be done so that troubleshooting becomes rather easy if the solution doesn't work for you. Check that verifier_verify_adb_installs is set to 1 in the global table.Ĭheck that as default, in the secure table:.if that is turn off, my problem is Shine. but both of them need usb debugging for remove pattern without remove files. i can issuse this whit 3rd softwere like shuami or whit adb command. In the global table, change the value for: for example i forgot the pattern of my devices.I'm running Linux and DB Browser for SQLite works well. Back it up at some other location too, and open the file in an SQLITE editor.Type: adb pull /data/data//databases/settings.db ~/ We need to tweak some parameters in settings.db. Repeat step 2 and 3 used in JB 4.2.1 method.JB 4.2.1 users can also follow this method if the previous one didn't work for them. You may verify that the echo command overwrote the file by using: adb pull /data/property/ ~/Īnd seeing the file's content in some text editor. In that case, I would suggest not using adb pull but doing: adb shellĮcho 'mtp,adb' > /data/property/ Note that sometimes Android doesn't understand the text file changes if the line terminator is 'DOS Terminators' which Notepad would probably do on Windows (mine is Linux so no issue here). Open that file in a text editor and you would possibly see mtp written there. Repace ~/ with home directory of your OS. Open a shell on PC and type: adb pull /data/property/ ~/ Boot into Recovery and mount Data partition.Since I would never try step 1., I would do the following: For Jellybean 4.2.1: You should try your pattern-cracking software (or whatsoever the genre it has) from inside the Stock Recovery to see whether it works with the former's environment (ADB shell available there or not).If your Stock Recovery allows ADB shell access then you may also consider this solution. Note that this method is tested on Stock Android 4.2.1 and Stock CM 12.0 (Android 5.0), both devices having custom Recovery (ADB always enabled as default). Based on OP's clarification done in the comments below Izzy's answer, I propose the following solution if one's device is locked out and ADB is not enabled under Settings.
