Q1. Can I install this OTA file with the SP Flash Tool?

No. Although this is a MediaTek-powered device, this specific file is an OTA update package designed for the stock recovery. It is not a full scatter-based firmware and cannot be flashed with PC-based tools. Attempting to do so will fail.

Q2. Can I use this firmware on my Archos 55 Helium Plus or 55 Helium Ultra?

No. The standard, Plus, and Ultra versions of the 55 Helium are different models with different hardware specifications (like RAM amounts or even chipsets). You must use the firmware that exactly matches your device name to avoid software conflicts or bricking your phone.

Q3. My phone is stuck on the Archos logo. Can I still use this method?

Yes, as long as you can still boot into the stock recovery menu (by holding Power + Volume Up), this method is the ideal way to fix a soft brick or bootloop, often without losing your personal data.

Archos 55 Helium Stock Firmware (OTA Update File)

The Archos 55 Helium is a 5.5-inch 4G LTE smartphone from the French company Archos, released in 2016. Running on Android 6.0 Marshmallow, it served as a budget-friendly large-screen device. If your phone is experiencing software glitches, is stuck in a bootloop, or you wish to perform a clean installation of the OS, using this official OTA (Over-The-Air) package from the stock recovery is the intended method for restoration.

Important Note: This is an official OTA update package designed to be installed through the device’s stock recovery menu. It is not a full firmware file for a PC flashing tool like SP Flash Tool. Ensure your data is backed up before proceeding.

Backup Your Data: While applying an OTA update doesn’t always wipe data, it’s highly recommended to back up all important files as a precaution. A factory reset may be required to solve certain issues.
Charge Your Device: Ensure your phone has at least 50% battery to prevent it from shutting down during the installation process.
Prepare a MicroSD Card: You will need a formatted microSD card with enough free space to store the update file.

🔧 Device-Specific Troubleshooting

“Signature verification failed” Error in Recovery: This error means the recovery does not recognize the file. This can happen if the download was corrupted, it is not the official file for the standard 55 Helium, or if your phone’s system has been modified (e.g., rooted). OTAs require a 100% stock system to install.
“Installation aborted” Error: This can indicate a problem with the microSD card or a corrupted download. Try using a different, freshly formatted microSD card (FAT32 is best). If the issue persists, a “Wipe data/factory reset” from recovery before applying the update might be necessary (this will erase all your data).
Cannot Boot into Recovery Mode: If you cannot access the stock recovery, its partition might be damaged. In this scenario, you cannot use the OTA method. The only alternative is to find a full, scatter-based firmware for this model and flash it using the SP Flash Tool to restore all partitions.
4G/LTE Not Working After Update: If you lose mobile data connectivity after a successful update, the first step is to check your carrier’s APN settings under mobile networks. If they are correct, booting back into recovery and selecting “Wipe cache partition” can sometimes resolve connectivity glitches without deleting your personal data.
