Important Note: Do not install factory image meant for a different T2e batch or lineage or /e/ OS before reading this
There are two batches of Teracube 2e (T2e) so far
- 1st batch - Serial number starting with 2020 (internal codename: zirconia)
- 2nd batch - Serial number starting with 2021 (internal codename: emerald)
How to identify the batch
Check Serial number (SN). (Under the battery or dial *#06#)
- The 1st batch starts with “2020” in their SN. Sample - 202011T2Exxxxxx
- The 2nd batch starts with “2021” in their SN. Sample - 202111T2Exxxxxx.
What’s different in the 2 batches
While all the hardware specs are still the same, we had to change the Trustzone and TEE (related to fingerprint, IMEI, etc). This means software builds are different. Both versions run Android 11 now. Check out A11 for the 1st batch here.
Update: There is a Lineage build for the 2nd T2e batch (SN: 2021) now.
/e/ OS Update: /e/ OS can now be installed on 2nd batch units as well. Read more here.
