Easy Installer not working with Teracube 2e

I’m trying to use the Easy Installer to install /e/ onto my Teracube 2e (emerald), but I keep getting this issue where it will reboot my phone in bootloader mode, but from there it will do nothing. My Teracube device will display the following:

Bootloader
Please connect your computer and use fastboot to interface with the device.
Visit (Android SDK Platform Tools website) for more information.

Am I missing something? I’ve tried to install drivers from the /e/ documentation website but it leads to a 404 Not Found screen.
If there is any more information needed please let me know. I’ve never dealt with rooting or flashing any mobile device before so I am essentially clueless. I may try using the platform tools if the easy installer continues to stall.

The /e/asy installer does not always make it easy. A secure installation can be achieved using fastboot commands. Follow the /e/documentation…

I’ve gotten it up to the part where i run the console command

fastboot flashing unlock

upon doing so it will display

< waiting for any device >

My Teracube is currently plugged in (i was able to reboot it with the adb reboot bootloader command), but I get zero prompts on the Teracube, and pressing on the volume up button does nothing.

Not sure where I should go from here. Do I need any additional drivers?

Also, when using the command

adb devices

my Teracube does not display when in bootloader mode, not sure if that is intentional or not

According to your picture you are in adb mode, but not yet in “bootloader mode”

Next step is:

adb reboot bootloader
fastboot devices

Alright, I restarted the phone and re-did the commands.

Nothing seems to appear when I use the command

fastboot devices

and

fastboot flashing unlock

does not prompt anything on the device, nor does pressing on the volume up button on the device progress the program in any way.

I’ve tried two cables, both can be used for data transfer, so that’s out of the question.

Find it strange that the

fastboot devices

command doesn’t prompt anything though?

fastboot devices – This fastboot command will list the devices connected to your host PC in fastboot mode.

Since you have not received any feedback from fastboot as with adb devices, this means that your host PC has no connection to your T2e.


Oddly enough it is, like in documentation, visible in the device manager. Though even after restarting my computer, I’m still unable to use fastboot at all.

Teracube 2e phones have recently had an update pushing them to from Android 11 to Android 13 on a stable branch. Could this also be causing these issues or is this irrelevant?

I’ve also tried installing two separate fastboot drivers by following /e/ documentation and other sources, both not installing onto the Teracube.

I’m completely lost as to what to do now. Am I completely unable to root or flash my phone ever?

You should know what it means when a :warning: is displayed in the Windows Device Manager. Solve this problem by changing the driver.

I’ve attempted to twice with two different drivers and neither were able to be installed. Currently I am redoing all the steps on a Linux laptop to see if I’m able to get passed the fastboot issue.

Good idea, as Linux does not require any drivers. Only adb fastboot is required
Install ADB and Fastboot on Ubuntu and other Linux

It worked perfectly on Linux! Thanks much!
