Samsung SM-M3070 Firmware Overview
What is the latest SM-M3070 firmware?
M3070ZCS4CWE1, released June 5, 2023 with Android 11. It is a security update on bootloader binary 4. The archive holds 20 official builds across 1 region (CSC).
Is the Samsung SM-M3070 still getting updates?
Most likely not: there has been no new firmware since June 2023, so Android 11 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Which Android versions did it get?
The SM-M3070 builds in the archive run Android 10 to 11. The earliest build we have for each version:
- Android 11: M3070ZCU4CUC6 (Apr 2021), 11 builds in total
- Android 10: M3070ZCU2BTD7 (Apr 2020), 9 builds in total
Can I downgrade the SM-M3070 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 2 to 4:
- Binary 4 — since Sep 2020
- Binary 3 — since Jun 2020
- Binary 2 — since Apr 2020
A phone already on binary 4 rejects builds with a lower binary in Odin ("SW REV CHECK FAIL"), so it can go back to an earlier Android version only if that version has a binary 4 build. How to read a build number.
