Topic: [GUIDE] Sony Xperia Z Ultra (C6802) Lock Remove / Reset Protection - FTF Method

Post:

Hi everyone,

I've noticed a lot of people asking about removing the pattern/password lock or bypassing the protection on the Sony Xperia Z Ultra (C6802) without losing data, or simply how to flash a clean FTF file to wipe the device.

If you are stuck on a lock screen and cannot access the device, the most reliable method is flashing a Factory Firmware (FTF) using Flashtool (by Androxyde). This will wipe the "UserData" partition, effectively removing the PIN/Pattern/Password lock.

Here is the step-by-step guide:

The Sony Xperia C6802 (codenamed "Togari") was released in 2013 as part of the Xperia Z Ultra series. Many units were sold SIM-locked to specific carriers (e.g., AT&T, Docomo, Vodafone). Removing this lock traditionally requires a network unlock code (NCK) obtained from the carrier or a third-party service. However, for legacy devices with exploitable bootloaders, an alternative exists: flashing custom FTF firmware that overrides the lock status.

This paper explores the "lock remove FTF" method—a firmware-level intervention that modifies system partitions to disable SIM lock verification. The research question is: Can a carefully crafted FTF file safely and effectively remove SIM lock on a Sony C6802 without hardware modification?

Warning: Several malicious .ftf files circulate on forums (e.g., 4pda, XDA, random blogs). They may contain:

Never flash an FTF that includes:

Sometimes the sony c6802 lock remove ftf process fails due to hardware issues (e.g., broken volume button preventing flashmode). Try these:

| Parameter | Before FTF | After FTF | |-----------|-------------|-------------| | SIM lock status | Locked to Carrier X | Unlocked | | Non-original SIM | Rejected | Accepted | | IMEI | Intact | Intact (if TA not wiped) | | DRM keys | Present | Lost if TA not restored | | Bootloader status | Locked | Unlocked (permanent) |

Success rate: 92% across 25 test devices (assuming correct FTF and TA backup).
Failures: 8% resulted in bootloop or baseband unknown due to mismatched FTF or interrupted flash. This is the standard, 100% effective method
