I am working with a Gemini devices GEM1000 tablet, I have performed all the steps to get adb working, and the device shows up under 'adb devices' so I go to the bootloader with 'adb reboot bootloader' and once in the bootloader, the device can no longer be descovered with 'adb devices' or 'fastboot devices'
checking 'lsusb' the tablet is not showing up as connected, although if I select "appply update with ADB" it then shows up as '2837487629 sideload' under 'adb devices' and then shows up in lsusb again
The recovery says 'Android System recovery <3e>' and 'Recovery system v4.2.41' in case that matters. Could it be possible I need to flash a different recovery? if so are there any generic recoveries?(since I doubt this generic tablet has any custom ones)
How do i get the device to show up in 'fastboot devices' once I enter recovery mode?
lsusb. I got confused by your last paragraph I guess. And yes:
<3e>is the "stock recovery", and there are several custom recoveries available, e.g. CWM, TWRP, Philz, AmonRa, and more. Not sure if they have any effect on bootloader/fastboot mode, so I better leave that to someone else now :)
