I have a Teracube One phone that will not boot, either normally or into recovery mode. Does anyone have any advice for how to recover this phone or, at the very least, retrieve data from it? Any magic button combinations I haven’t tried? Any way to get the phone to act like a hard drive I can mount long enough to get my data off it? Any possible last ditch stuff like taking it apart?
Here’s what happened and what I’ve tried:
Today, the phone was running fine and then all of a sudden turned itself off (it was just sitting on a table). I held the power button. The Teracube logo came up briefly, but the phone immediately shut itself down again. I thought it might have a dead battery, but it shows the same behavior when plugged in and also after being left alone to charge.
I followed the procedure to boot to recovery mode, but the phone will not boot to recovery mode either. It simply does the same thing. I hold power + volume up, the phone shows the menu, I select recovery mode and press volume down. The Teracube logo displays briefly, but then the phone shuts off. I’ve tried this a dozen times at this point and it’s the same thing every time.
Right now, the only thing I seem able to do is boot to factory mode: holding power + volume DOWN for awhile (~10 seconds), the Teracube logo shows up and then the phone boots to a text-only screen with “Factory Mode” at the top. There are a number of options for testing the phone and erasing the eMMC as well as rebooting (rebooting from here doesn’t help).
P.S. The real pisser is that this phone is the one I received a bit over a year ago after the screen on my previous Teracube One was destroyed: Factory reset Teracube One with inoperable touchscreen (no display, no touch) . I was hoping it’d last a few years.
