The G3311 is the single-SIM variant of the Xperia XA1 Plus, released in 2017 running Android 7.0 Nougat (upgradable to 8.0 Oreo). Its security architecture, particularly the TrustZone and Secure Boot, makes lock removal complex.
USERDATA (this removes lock data)CACHE and APPSLOGSYSTEM, TA (keep them safe unless troubleshooting)The Sony Xperia XA1 Plus (G3311) is a device built on the MediaTek (MTK) platform, specifically the MT6753 chipset. Unlike the older Xperia lines that relied heavily on S1 protocol bootloaders that were notoriously difficult to crack, the G3311 presents a different challenge.
An FTF file for lock removal is essentially a repacked firmware image that has been modified to bypass the standard security checks during the flashing process. When you load this file into Emma (Sony’s official flash tool) or third-party alternatives like Flashtool (by Androxyde), you are attempting to rewrite the phone's partition table.
Specifically, this FTF targets the TA partition (Trim Area). This is the holy grail of Sony hardware—it holds the DRM keys, the device configuration, and crucially, the SIM lock and bootloader status. A "lock remove" FTF attempts to flash a "clean" or patched TA partition, tricking the bootloader into thinking it was never locked, or resetting the SIM lock counter to zero. sony g3311 lock remove ftf
Cause: You forgot to check WIPE USERDATA in Flashtool.
Fix: Repeat the process, ensuring USERDATA is ticked.

Title: The Locked G3311
Leo stared at the old Sony G3311 on his workbench. The phone had been sitting in a drawer for two years—a relic from a forgotten family member, locked with a passcode nobody remembered.
He’d tried everything: factory reset via recovery mode, Google account tricks, even digging up old service manuals. But the FRP lock (Factory Reset Protection) held tight, like a digital ghost guarding the past.
Then, in a forgotten forum thread from 2019, he found a clue: a custom FTF firmware file—stock Android 7.0 Nougat, but modified to skip setup wizard locks. The filename was cryptic: G3311_Custom_NoFRP.ftf.
Risking a brick, Leo fired up FlashTool.
