It is incredibly disheartening when your VIVO Y15s, which you just factory reset, suddenly stops at the verification screen showing "This device was reset; to continue, sign in with a Google account that was previously synced on this device." You have tried entering every Google account you can remember, yet the system keeps rejecting them,m and the device simply will not proceed to the home screen. In this state, your VIVO Y15s becomes completely unusable; le you cannot make calls, open apps, or even access basic settings. Many users eventually give up and take the phone to a repair shop at a considerable cost, when in reality there are multiple methods you can try yourself at home, as long as you know the correct steps.
The issue you are facing is known as FRP Lock, short for Factory Reset Protection, a built-in security feature introduced by Google starting with Android 5.1 Lollipop and mandated for all Android manufacturers, including VIVO. FRP’s original purpose is truly noble: to protect your device if it is lost or stolen, so thieves cannot simply perform a factory reset and then use or resell the phone as a new unit. The moment you add your first Google account to the VIVO Y15s, FRP activates automatically in the background. If the device is ever reset, whether through the Settings menu or via Recovery Mode without first removing the linked Google account, the system will force you to sign back in using the exact same account that was last synced before the reset. Without the correct email and password, the device will remain permanently stuck on that verification screen.
While extremely useful for security, FRP often turns into a "double-edged sword" for the legitimate owners of the VIVO Y15s itself. Many common scenarios trap users in this FRP lock: you may have forgotten the details of a Google account you set up years ago, recently changed your Gmail password and cannot recall the new one, bought a second-hand unit from a friend or online marketplace only to discover the previous owner forgot to log out of their account, performed a hard reset from Recovery Mode because you forgot your pattern/PIN without realizing the FRP consequence, or even had a child at home accidentally trigger the reset process. Specifically for the VIVO Y15s, which ships with various builds of Funtouch OS and different security patch levels, not every FRP bypass method works on every unit. A technique that succeeds on Android 11 may have already been patched and no longer function on Android 12 or 13 with the latest security updates.
This article has been specifically compiled as the most complete and structured guide to resolve the VIVO Y15s being stuck on Google account verification (FRP Lock) after a factory reset. We will cover every method proven effective by VIVO Y15s users, ordered from the safest and official options first, through to more technical approaches requiring supporting tools. You will find instructions on how to officially recover your Google account if you still have access to your recovery phone number or backup email, various PC-free FRP bypass methods using the TalkBack feature, helper APKs such as VNROM and Quick Shortcut Maker, and attempts using secret VIVO dialer codes. For more stubborn cases where PC-free methods fail due to updated security patches, we also provide detailed steps using computer-based software like UnlockTool, DroidKit, UnlockGo, and similar tools capable of removing VIVO Y15s FRP in just minutes. Each method is explained sequentially, along with notes on supported Android versions, required tools, and warnings about critical steps to help you avoid mistakes even if you are a complete beginner who has never attempted anything like this before.
By following this guide from start to finish, you will not need advanced technical skills or specialized equipment to restore your FRP-locked VIVO Y15s to full working order. We will walk you through initial preparations (checking the OS version, preparing a USB cable, ensuring sufficient battery charge), trying the official account recovery method, step-by-step PC-free bypass for various scenarios, all the way to PC software guides for the most difficult cases with the latest security patches.
