Archos 50 Helium Plus Firmware Flash File Download [Stock Rom]

The Archos 50 Helium Plus is a 5-inch, 4G LTE smartphone from 2015. It is powered by a MediaTek MT6735 processor and runs on Android 5.1 Lollipop. This guide provides an official OTA (Over-The-Air) update package to allow users to manually update their phone’s software to a newer build, which can improve stability and fix bugs.

Important: This is an OTA update file, not a full unbrick package. It is designed for updating a functioning phone that can boot into its stock recovery mode. This process will not wipe your data, but a backup of important files is always highly recommended before any software installation.

How to Manually Install OTA Updates

Manually installing an OTA update on your Archos 50 Helium Plus is a simple process for a working device. The easiest method is to place the downloaded OTA .zip file onto a microSD card, then boot into the phone’s stock recovery mode and select the “Apply update from SD card” option. This will install the official update without erasing your data.

For detailed, step-by-step instructions for both the SD Card and the more advanced ADB Sideload methods, please follow our comprehensive pillar guide: How to Manually Install Official OTA Updates on Android.

Device-Specific Troubleshooting for Archos 50 Helium Plus

• “Update Verification Failed” or “Installation aborted”: This is the most common error. It means the OTA package is not compatible with your current software. This can happen if your system has been modified (e.g., rooted, custom recovery installed), or if you are trying to skip a required intermediate update. You must be on official, unmodified firmware to apply an OTA.
• This is NOT an Unbrick File: An OTA .zip file is designed to update a device that can boot into its recovery mode. If your phone is hard-bricked (won’t turn on), you need a different type of firmware (a full SP Flash Tool scatter package) and a different flashing method. This file will not fix a dead device.
• Model Confusion: The Archos “Helium” line has many models (50 Helium, 55 Helium Plus, etc.). This OTA is specifically for the Archos 50 Helium Plus. Do not attempt to install it on a different model.
• Insufficient Storage Error: The update will fail if there isn’t enough free room for the system to unpack the update file. Make sure you have at least 1-2 GB of free space before starting, or use the recommended SD card method.

FAQs

Q1. My phone is stuck on the Archos logo. Can I use this file?

Maybe. If you can still boot your phone into recovery mode (by holding Power + Volume Up), you can attempt to flash this OTA file. If you cannot get to recovery mode, then your device is likely bricked and you will need a full unbrick ROM and the SP Flash Tool.

Q2. Will this update erase my data?

No, a standard OTA update does not wipe your personal data. However, it is always a good practice to back up important files before any software update, just in case.

Q3. Do I need to unlock the bootloader to install this update?

No, official OTA files are signed by the manufacturer and can be installed on a device with a locked bootloader using the stock recovery.
