Hello, there was a notice for a update on my Teracube 2e. I have clicked install. Download and install and update and reboot runs few hours. After a reboot, there is always the old OS installed and the same notice is displayed. I have run this 2 times. It has no effect.

What is the problem?
Same with me. I have two Teracubes 2e (bought in May '23), one of which could not be updated for a year now (Android 11, iodéOS 2.11). I contacted Antoine for help from iodé but received none. In July I posted a request to the community - no reply either (Teracube 2e - update 2.12 coninuously failes). I was thinking I was the only one with this sort of problem … Tried updating several times, nothing worked, even reset to factory settings failed solving the issue.
Try the following: open “iode news” on your phone, choose “join/participate” (or whatever the Englisch word for “Mitmachen”), then “Become a beta tester” and follow the link (github). Donwload the installer (it replaces the one on your phone). I tried this for one of the two Teracubes and it worked. The phone even got promoted to Android 12 (very nice), iodé is now 3.10. There is a downside, though: Being a beta tester means that some updates may not work properly - one crashed my phone entirely and I lost everything.
But then … since there are now two of us, maybe we get heard in the community! In any case, keep me informed.
Hello bomdomqw1,
today, a update to 2.20 was displayed. I have run the update (download, install, reboot = 6 hours?) without errors or warnings and it is the same: No changes. Still 2.10 is installed.
I had tested to display the boot display. This is very difficult. I had try different key pressing and after a long time the boot display was displayed. I don’t remember me, wich was the correct key press. Then I had choice Fastboot. Then “=> Fastboot …” was displayed and no key press changed this. I must remove the battery.
Its frustrating. No FM Radio. Bad cam. No Updates. No or bad support.
What is your Teracube 2e version?
Serial Number: 2020… = codename “zirconia”
Serial Number: 2021… = codename “emerald”
Works the FM Radio on your Teracube 2e?
it’s frustrating …

Unlock Bootloader?
If you unlock the bootloader, you will be able to install custom operating system software on this phone.
A custom OS is not subject to the same testing as the original OS, and can cause your phone and installed applications to stop working properly.
To prevent unauthorized access to your personal data, unlocking the bootloader will also delete all personal data from your phone(a "factory data reset").
Press the Volume Up/Down to select Yes or No.
Yes (Volume Up):Unlock(may void warranty).
No (Volume Down):Do not unlock bootloader.
→ Press: VOLUME UP
Select Boot Mode:
[VOLUME_UP to select, VOLUME_DOWN is OK.]
[Recovery Mode]
[Fastboot Mode] <<==
[Normal Mode]
=> FASTBOOT mode...
→ do nothing. respectivelly no reactions by key press.

Unfortunatelly the FM Radio still don’t work, because iodé is based on LineageOS:
[Teracube 2e 2nd Batch (SN: 2021)] LineageOS 21.0 [emerald]
What does not work?

Hi Miria, I have never tried to flash a device, so I cannot comment on your efforts, but they look impressing (and complicated)! I just downloaded a new updater from github as beta-tester, since (again) updates didn’t work. But now the phone is stuck to the start screen with the “iodé”-lettering.
LVE tells (Mise à jour bloquée à 2.11 - #3 by LVE) there are more of us with the same problem, but apparently Antoine from iodé didn’t help either.
Any suggestions how to go to “factory-settings” with the startscreen stuck? It IS frustrating indeed!
Hi Miria, I have no radio installed on my phone. The camera works properly and I like the pictures. Since my phone crashed again after an update, I can’t tell what version I have, but I am pretty sure it is 2021 emerald.
Hello @bomdomqw1 , i had read that there is a backup tool for the settings, and with the initializing (screen procedure) of a newly installed/flashed OS there is the question similar to “would you be loading a setting backup file?” I did not make a backup, unfortunatelly.

You find the serial number inside the phone under the battery, also after remove the battery.
Let use wait for the next update (2.21).
Maybe a short version of flashing a Teracube:
1.) LINUX: Download a OS fastboot package
→ Download to the Linux PC
→ Example: iode-2.20-20240218-emerald-fastboot.zip
→ Open the directory in terminal.
→ Unzip: unzip iode-2.20-20240218-emerald-fastboot.zip
→ Go into the unzipped directory.
2.) PHONE: Activate the FASTBOOT mode
→ connect the device via USB with the PC
→ Shutdown the OS (Power Off)
→ Press: Power + Vol+ (to come into the boot manager. It’s very difficult.)
Select Boot Mode:
[VOLUME_UP to select, VOLUME_DOWN is OK.]
[Recovery Mode]
[Fastboot Mode] <<==
[Normal Mode]
→ Press: VOLUME UP (select)
→ Press: VOLUME DOWN (OK)
=> FASTBOOT mode...
3. LINUX: Flashing an OS to the phone
→ Go into the opened Terminal
Check the USB connection:
→ type: lsusb
A entry must be displayed like:
Bus 002 Device 033: ID 0c4b:201d MediaTek Inc. Android
// eventually? → Type adb reboot bootloader
Skip this point by your first running. Maybe it is not necessary.
Is adb not installed, install it. The instruction is displayed in the terminal.
Flash the OS to the phone:
→ type: fastboot flashing unlock
Is fastboot not installed, install it. The instruction is displayed in the terminal.
