Samsung SM-A7070 Firmware Overview
What is the latest SM-A7070 firmware?
A7070ZCS3CWE1, released June 1, 2023 with Android 11. It is a security update on bootloader binary 3. The archive holds 20 official builds across 1 region (CSC).
Is the Samsung SM-A7070 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-A7070 builds in the archive run Android 9 to 11. The earliest build we have for each version:
- Android 11: A7070ZCU3CUC4 (Mar 2021), 9 builds in total
- Android 10: A7070ZCU3BTD1 (Apr 2020), 8 builds in total
- Android 9: A7070ZCU2ASL2 (Dec 2019), 3 builds in total
Can I downgrade the SM-A7070 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 3:
- Binary 3 — since Jan 2020
- Binary 2 — since Dec 2019
A phone already on binary 3 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 3 build. How to read a build number.
