Some users dislike EMUI 12’s battery drain or missing features. Downgrading is possible but wipes all data.

Official method (HiSuite Rollback):

Manual method (Unsupported): Download the EMUI 10 firmware for C605 via dload method. Note: Downgrading may trip the anti-rollback (ARB) counter, permanently preventing re-upgrade to EMUI 12. Do this only if you understand the risks.

| Problem | Solution | |---------|----------| | “Software install failed” (dload) | Wrong cust. Extract cust.img from correct firmware and flash via fastboot | | No mobile network after flash | Reflash modem image (modem_na.img) from stock LX3A firmware | | Bootloop after EMUI 12 | Factory reset from recovery (Vol Up + Power) | | HiSuite says “no updates” | Change proxy port to 7777 and disable antivirus | | Touchscreen inverted | You flashed LX1A firmware – reflash correct LX3A version |

This is the standard method for users who cannot get the update via OTA or need to unbrick their phone. You will need a MicroSD card and a Windows PC.

You need the "Full OTA" image. Since the MAR-LX3A is a Latin American model, you generally want the firmware tagged for that region (often labeled C185, C432, or specific carrier codes).

Search for “Huawei Latin America Support” and enter your Model (MAR-LX3A). Some regions provide direct download links for recovery firmware.
