Retrieve Files From Device in Bootloader I'm working on an android application. I accidentally turned on a developer option(I'm guessing RTL Layout), and now I get the message "..System UI has stopped working". I tried to clear the cache partition in recovery mode and that did nothing. I don't mind doing a factory reset but I just want to get files off the phone as I don't believe a backup. (My phone is the Droid Turbo if that matters)
When I connect it to my computer via USB it is not recognized. I believe it was set as PTP connection on my phone. It does not show up when I run adb devices. However in recovery mode, when I choose "apply update from ADB" it shows up when I run adb devices(with the word sideload next to it), but I cannot seem to find it in the device manager. I tried to pull/backup through adb but I get "error: closed". Is there any way to retrieve my photos/etc before/after I factory reset. Thanks!
Did u tried to boot phone to fastboot mode, on my phone I do that this way:
 Pull out battery for 5 sec, put battery back, an then hold power + volume down key.
Than u can try using pull command.
What device do you have?
