Frequently asked questions
Will a hard reset delete everything on my Lenovo S90 Sisley?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Lenovo S90 Sisley to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the Lenovo S90 Sisley 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 Lenovo S90 Sisley?
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 Lenovo S90 Sisley?
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 Lenovo S90 Sisley?
Use the Hard Reset method above if your Lenovo S90 Sisley 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.
What is recovery mode on my Lenovo S90 Sisley?
Recovery mode is a stripped-down menu outside the normal operating system, used to wipe data or apply updates when the Lenovo S90 Sisley won't boot normally. See the Enter Recovery Mode section above for how to reach it on this device.
How do I format my Lenovo S90 Sisley?
"Formatting" and "factory resetting" mean the same thing for the Lenovo S90 Sisley — both erase all data and restore default settings. Use whichever method above matches your situation.
