For the Redmi Note 10S (rosemary), unlocking the Mi Account and FRP typically requires specific partition addresses and an MTK-compatible tool. Since this is an MTK (MediaTek Helio G95) device, you can use the SP Flash Tool method with a scatter file or a dedicated bypass tool.1. Address Method (SP Flash Tool)
To use this method, you need the stock scatter file for the “rosemary” firmware. You can use MTK Auth Bypass Tool to disable the SLA/DAA protection before flashing.
Lock Type
Linear Start Address
Partition Length
Mi Account
0x4d80000
0x2000000
FRP (Google)
0x5a00000
0x100000
Note: These addresses are standard for the Note 10S (rosemary), but always verify them by opening your MT6785_Android_scatter.txt file in a text editor and searching for the persist (for Mi Account) or frp partitions.
SP Flash Tool (V5 or V6): Used for the “Format Manual” tab.
MTK Auth Bypass Tool (LibUSB): Essential to bypass the Secure Boot without a paid authorized account.
USB Drivers: Ensure MediaTek Preloader drivers are installed.
3. Step-by-Step Guide
Preparation: Open MTK Auth Bypass Tool and click on “Disable Auth.”
Connection: Power off the phone. Hold Volume Up + Volume Down and connect the USB cable. The tool should show “Success” or “MTK Auth Bypassed.”
Flash Tool Setup:
Open SP Flash Tool.
Select the Scatter-loading file from your stock firmware folder.
Go to the Format tab and select Manual Format Flash.
Execute:
Enter the addresses provided above for either Mi Account or FRP.
Click Start. It should complete in a few seconds with a green checkmark.
4. Anti-Relock Note
If the Mi Account relocks as soon as you connect to Wi-Fi, you may need to use a “Mi Account Unlock File” specifically designed to disable the finddevice.apk or use a “Micloud Disable” tool.
Another effective free method for “rosemary” is using the “UnlockTool” (if you have access) or “Android Multi Tool” which often has a one-click button for “Xiaomi Mi Account Reset” specifically for this model.
