[Q] How to get Onda v973 to boot into recovery via power/home buttons
Title pretty much says it all, trying to figure out how to get a Onda v973, I think version 2 to boot into recovery via the power/home buttons. Which are the only buttons on the device. I was able to get it to boot into recovery via adb reboot recovery. Seems there was a way with v971 and v972 if you hold the home button + power till the logo comes up. But when I press the home and power, the device never turns on. It will only turn on if just the power button is pressed. Though I do hear it making some sound at one point when I have both depressed.
I have CWM and Cyanogenmod 10.1 installed on my v973. I did not turn off signature verification, the compatibility package failed, and I did not catch that till after I rebooted. Now I have both on there, but no touch screen drivers. With USB debugging not enabled, when the device boots it shows in adb devices, but is unauthorized. I am just trying to reboot into recovery/CWM so I can turn off signature verification, install the compatibility package, and have a working tablet again.
Even with stock firmware I could not get it to enter recovery. I started by using the upgrade tool to install TWRP. Then had to use adb reboot recovery to get into TWRP. Which did not have working touchscreen drivers. I could not get the device to stop booting in recovery mode/TWRP. I then used adb to push CWM to the device and cat it to overwrite TWRP. From there used CWM to install Cynogenmod and stop booting into recovery. I did backup the factory rom, but never got a chance to download it from the internal storage.
I will try using the PhoenixSuit to restore a stock firmware and start over again. But do not run Windows, attempting to use it via Windows running in VirtualBox on Linux. Either way, still would like to know how to get this device to boot into recovery using power/home buttons. I have asked Onda the same question. Does seem like its changed since previous models and/or versions. Hopefully there is a way as if not will be the first android device I have come across with no physical means to enter recovery mode.
