Xperia Tablet Z (SGP 321) Too Many Patterns Attempt Done via Flashtool.

Problem : Too Many Patterns Attempt

Tools - Firmware - Procedure

1) Flashtools: Download Here

2) Latest Firmware:  Download Here

3) paste the ftf file downloaded in step c) to folder „Firmware“ included in the XPERIA Flashtool

4) open the XPERIA Flashtool, click on flash and choose downloaded firmware, than click ok. Important - if you do not want to delete any data of your phone, just uncheck flashing userdata.sin file. All data will remain in your phone, but sometimes it can cause additional troubles. So it is better (and I recommend that) to do the backup of your personal data, than proceed with clean instalation and then restore your personal data.

5) turn off your tablet and when Flashtool shows pop up window, connect tablet to PC with holding volume down button

6) after few minutes all is done and your tablet gets the new firmware
