Guide to install iode OS on Teracube 2e (SN:2021) using a Mac and terminal

A more comprehensive guide on how to install iode from stock OS on terracube


  1. Update the stock firmware on teracube to the latest
  2. Follow Unlock the Bootloader
  3. If you are not in fastboot mode, then enter fastboot mode again
  4. Type fastboot flash boot iode-emerald-recovery.img and press enter… (make sure you have the latest iode-emerald-recovery.img, filename can be different)
  5. Reboot to recovery using fastboot reboot
  6. You will see an iode OS recovery page. From recovery => Factory reset => Format Data/factory reset
  7. Go back to the main recovery page, then from recovery => Apply update => Apply from ADB => type in adb sideload hit the spacebar and drag in latest [] into terminal and hit enter. This will take 5-10 minutes to complete.
  8. Once the installation has been completed, go back to the recovery page and hit reboot, and you should have iode installed.

Please comment below if you have edits or further instructions, and I will add them to the guide.

Best of luck! :grinning:

I saw on the website only the 2021 / 2022 version. (iodéOS installation - iodé)

Does this installation for the 2020 (Zirconia) model?

@curiousAndreas Not that I have seen. You’d have to contact the iode OS developers to see if you could use the 2021 installation guide and files or if they have separate support for the 2020 model. Doesn’t look like it.

The same instructions may not work for Zirconia (2020) and may damage the partition table. Please be careful.

WARNING: Left out this crucial important step below. Can’t seem to edit the post!

Step 3 should be: Settings > system > advanced > developer options > enable OEM unlocking and USB debugging.

I changed your steps a bit in the original post. Let me know if the changes look good.

Perfect thanks. I was going to link but I wasn’t able to add more than two links.
It will need an edit tho as I have completed the installation but the phone was corrupted. Waiting to hear back from the iode devs to see why. There are no further instructions from them on their basic guide.

I recommend this guide if you want to start from a clean state again.

After trying to install multiple times and receiving no help from the iode community this guide appears to be incomplete.

All attempts have ended in corruption of the phone so far and having to revert back to stock OS.

The following errors show up on the iode recovery screen:
" Failed to mount/metadata: invalid argument"
" Cannot mount / metadata/ota"

If anyone knows what is missing/wrong with the guide. Please share.
