Is there a universal way to enter recovery mode on an Android device with only one turn on/off button? I have a tablet (Navon Raptor 7) like this and I can't figure it out. An other problem is that although it can boot and get to the launcher, basically I can't start any application or get to the settings (it says 'xy application stopped' etc.) so I can't even activate debug mode and use adb to achieve this. That's why I want to do a hard reset from recovery...

Please edit your post down to one question, and create new posts to ask any further questions. You'll get better answers that way. To the first question: No, key-combos differ between devices (see also our recovery-mode tag-wiki). – Izzy Mar 18 '14 at 15:49
  • My only question is what's in the title. The other stuff is just for prevent answers like 'go to the settings...'. So maybe I should disassemble and see if there is an inner switch or something? – CompanyCodeMonkey Mar 18 '14 at 17:14
  • You might try a Google-Search on "Navon Raptor 7" hard-reset. There are even some youtube tuts listed. Most of the results are Hungarian, though. I was hoping for a link to hard-reset.com (they always list along how to enter recovery mode for that), but unfortunately there seems to be none... – Izzy Mar 18 '14 at 17:25
  • I speak Hungarian but there seems to be absolutely nothing about reseting it with hard keys. I found out that this device is in close relationship with the Icoo D70 Pro II, which has slightly bigger community but still no hits for reseting. – CompanyCodeMonkey Mar 18 '14 at 17:42
  • According to this video, the "Navon raptor 7"" tablet is supposed to have the hardware volume buttons. Are you saying that yours doesn't have them? – Chahk Mar 18 '14 at 19:10

You can use apps like Quick Boot or Rebooter or some root apps have this feature to go to recovery mode.. Use them

  • Yes, I found them in Google but every one of them starts like 'enable debug mode on the phone...' or not? – CompanyCodeMonkey Mar 18 '14 at 17:19
  • They just need root access – Alexander The Great Mar 18 '14 at 17:21
  • Thats bad enough because I have the original not rooted ROM on this tablet :C . Oh and I cant run any apps on the tablet, it's a total mess. – CompanyCodeMonkey Mar 18 '14 at 17:22
  • Without root access I think only way is hard key combos. – Alexander The Great Mar 18 '14 at 17:24
  • Yeah that is my conclusion too but how to do that with only 1 key? – CompanyCodeMonkey Mar 18 '14 at 17:25

You can use the following command from an adb prompt to enter into your devices recovery mode without using a physical button during restart.

1) Start adb prompt on your PC / MAC / Linux

2) Make sure adb is running adb start-server

2) Make sure the device is present when you run: adb devices

3) Now run adb reboot bootloader and your device will restart into recovery mode
