Firmware Oppo A57s [extra Quality] May 2026
⚠️ Important: The OPPO A57s runs on MediaTek Helio G35. Firmware updates are usually handled via OTA (Over-the-Air). Manual flashing is only recommended for unbricking, fixing boot loops, or downgrading.
Problem #3 – Wi-Fi disconnects during sleep
The firmware’s power management was too aggressive, turning off Wi-Fi to save battery.
Fix: A.10 (January 2023) introduced a “Keep Wi-Fi on during sleep” toggle that actually worked — previously the firmware overrode it.
5. Major Android Updates (Firmware Evolution)
OPPO promised one major Android update for the A57s (typical for budget phones).
| Update | Firmware Version | Release | Changes |
|--------|----------------|---------|---------|
| Android 12 → 13 | CPH2387_11_C.20 | July 2023 | Android 13 + ColorOS 13 (Aquatic Design), new media player, improved privacy indicators, better RAM expansion. |
| Security patch only | C.22 | October 2023 | October 2023 security patch, fixed a Bluetooth stability bug. |
| Security patch only | C.24 | January 2024 | January 2024 patch, improved thermal throttling during summer. |
| Final known firmware | C.26 | April 2024 | April 2024 security patch, fixed a bug where notifications wouldn't clear. |
After C.26, OPPO moved the A57s to quarterly security updates (as per their policy for budget devices).
No Android 14 – the MediaTek Helio G35 and limited eMMC storage made Android 14 too heavy; OPPO confirmed this in a community post in May 2024.
8. Conclusion
The OPPO A57s firmware is stable for daily use but sensitive to cross-version flashing. Always perform a full backup of nvram/nvdata using MTK Meta Mode or SP Flash Tool readback. For bootloop repairs, prefer re-flashing only super and boot before attempting a full firmware reinstall.
