Frequently asked questions
Will a hard reset delete everything on my Archos 55 Cobalt Plus?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Archos 55 Cobalt Plus to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the Archos 55 Cobalt Plus remove the SIM lock or carrier lock?
No. A hard or factory reset only clears data and settings — it doesn't remove a carrier/SIM lock, which is tied to the device's IMEI at the network level. You'd need to contact your carrier for an unlock.
How long does a factory reset take on the Archos 55 Cobalt Plus?
Typically a few minutes, though it can take longer on older or heavily used devices as more stored data has to be wiped.
Will I need my Google account password after resetting the Archos 55 Cobalt Plus?
Yes, if Factory Reset Protection (FRP) is enabled. Android (and HarmonyOS 2.x devices with Google services) will ask for the last signed-in Google account after a reset — make sure you know that password first.
How do I reset my Archos 55 Cobalt Plus?
Use the Hard Reset method above if your Archos 55 Cobalt Plus is frozen or won't respond, or the Factory Reset method if the screen still works normally — both are covered step by step on this page.
Can I factory reset my Archos 55 Cobalt Plus without the password?
Yes — resetting through recovery mode doesn't require your lock screen password, since it bypasses the login screen entirely. That said, Factory Reset Protection may still ask for your Google account credentials afterward as an anti-theft measure.
Does my Archos 55 Cobalt Plus have a hard reset button?
Not a single dedicated button — the Archos 55 Cobalt Plus uses a button combination instead of one labeled "reset." See the Hard Reset section above for the exact keys to press.
