FRP Lock (Factory Reset Protection) is the Android equivalent of Apple's iCloud Activation Lock. After a factory reset, the device requires the credentials of the Google account that was last signed in. Introduced in Android 5.1 (Lollipop), FRP is now standard across all Android devices.
For wholesale buyers, FRP-locked Android devices are functionally bricked from a resale perspective. Unlike some iCloud Lock scenarios where partial workarounds exist on older hardware, FRP is robust on modern Android and there is no legitimate bypass: the device requires the original Google account credentials or a documented account-removal flow through the original purchaser.
Wholesale verification: on Android, ensure a sample of stock has been properly factory-reset and walks through the setup wizard without prompting for any Google account beyond the new owner's. Samsung devices additionally have Samsung Knox, which can lock devices independently of FRP; check for Knox warranty void status (Settings > About phone > Software information) on Samsung lots.
What does FRP stand for? The full form of FRP lock
FRP stands for Factory Reset Protection. That is the full form of “FRP lock”: a security layer Google added in Android 5.1 (Lollipop) that ties a device to the Google account signed in on it. Once an account is synced and a screen lock is set, the phone remembers that account through a factory reset, so a stolen or lost device cannot simply be wiped and reused.
Exactly when FRP triggers
FRP does not fire on every reset. It triggers when a device is wiped without the Google account being removed first. According to Google's Android documentation and device makers such as Samsung, the distinction is between a trusted and an untrusted reset:
- Trusted reset (no lock): erasing from within Settings, after entering the screen lock and removing the Google account, clears FRP cleanly. This is the correct way to prepare a device for resale.
- Untrusted reset (locks the device): wiping through recovery mode with the hardware buttons, or a remote wipe via Find My Device, while a Google account is still synced, leaves FRP armed. On the next setup the phone demands the credentials of the last Google account used.
One practical detail traders hit: the account used to clear FRP must have been on the device for a period before the wipe (Google enforces a waiting window, commonly cited around 24 to 72 hours), which is designed to stop a thief from adding a fresh account and wiping immediately.
What “FRP status: triggered” or “FRP locked” means
When a lot listing, a diagnostic report, or a device manifest says FRP status: triggered or FRP locked, it means those units will stop at a Google account verification screen during setup and cannot be used until the correct previous Google credentials are entered. In wholesale terms the device is not usable stock: it will not onboard to a new user, and no buyer downstream can activate it. “FRP status: not triggered” or “FRP clear” means the units completed a proper reset and are ready to set up.
The only legitimate way to clear FRP
There is no legitimate technical bypass on modern Android. The lawful resolution is account-based: the previous owner signs in with the original Google credentials, or, better, removes the Google account from the device before the reset so FRP never arms. For business fleets, the enrolling administrator removes the device from management first. Aikon does not endorse or describe FRP bypass tools; they are not a legitimate resolution, they are frequently associated with stolen handsets, and carriers and reputable refurbishers reject FRP-locked stock outright rather than risk it. Treat any lot that leans on a “bypass” as a lot you cannot lawfully clear.
How wholesale buyers should treat FRP-locked lots
- Price them as non-working. FRP-locked units are effectively bricked for resale. Value them at parts or chassis level, not as functional handsets, unless the seller can supply verified account removal.
- Put it in the listing language. Stock should be described honestly as “FRP clear” or “FRP locked, account not removed” so counterparties price the risk correctly.
- Build it into intake checks. Factory-reset a sample and confirm each unit completes the setup wizard without asking for any Google account beyond the new owner's. On Samsung lots also check Knox warranty status (Settings > About phone > Software information), which can lock devices independently of FRP.
FRP vs iCloud Activation Lock vs MDM
Buyers often blur three different locks. They behave similarly at the setup screen but come from different systems:
| Lock | Platform | What arms it | Who can clear it |
|---|---|---|---|
| FRP (Factory Reset Protection) | Android | Reset while a Google account is still synced | The previous Google account holder |
| iCloud Activation Lock | iPhone and iPad | Find My enabled at reset with an Apple Account signed in | The original Apple Account holder |
| MDM enrolment | iOS and Android | Device enrolled in an organisation's management | The enrolling organisation's admin |
A device can carry more than one of these at once, so a clean IMEI does not by itself mean a clean activation state. Check each lock type separately on any lot before you commit.
