Step 6: First Boot After Lock Removal

1. Disconnect the USB cable.
2. Press and hold the Power button until the phone vibrates.
3. The first boot will take a long time (up to 10 minutes) because it is rebuilding the cache and userdata partition.
4. The device will boot directly to the Android Setup Wizard.
5. There will be no PIN, password, or Google FRP lock (provided you wiped userdata).

Step 4: If You Also Need to Remove FRP (Google Account Lock)

Flashing with wipe USERDATA does not remove FRP on Android 6.0+. After flashing, you still need to bypass the Google account verification.

Simplest way after FTF flash:

• Use FRP bypass tools (e.g., SamFw FRP Tool, or manual via test menu).
• Or flash a customized FTF from a region that doesn't enforce FRP as strictly (e.g., older Android 5.1.1 FTF).
• Or use OEM unlocking + fastboot if bootloader is unlockable (but that wipes DRM keys).

Step 2: Download the Correct Sony E6833 FTF File

This is the most sensitive part. You cannot use a generic “lock remover” tool. You need the exact stock ROM.

• Find your customization number: Originally, you could dial *#*#7378423#*#* (Service Info > Software Info), but since you are locked out, you need to guess based on your region (e.g., CE1 for Central Europe, RU for Russia, AU for Australia).
• Trusted sources: Download the FTF from XDA Forums or dedicated Sony firmware collections. Look for a filename like: Sony_E6833_32.4.A.1.54_CE1.ftf (where 32.4.A.1.54 is the Android 7.1.1 Nougat build).
• Critical step: Ensure the FTF contains the userdata.sin file. This partition holds the lock data. Without it, the lock will remain.
