Hey guys

I am trying to flash the generic UK rom on my Xperia Z using flashtool but it gets stuck at 0%, It doesn't even flash anything the phone stays intact. Does anyone know how to sort this?

I found out that i was not using the Beta5 version which is the one indicated for the Xperia Z and now im facing a different problem,

The phone doesn't stay in flashmode for more than some 30 seconds, then it disconnects and boots normally and i still can't flash the phone.

Yes it is, it happens for all xperia models
Ll give you the idea
1. Install flashtool beta 5
2. Install Xperia Z flashmode and fastboot drivers from drivers folder of flashtool installation directory
3. Copy the ftf to firmwares folder
4. Don't connect the phone, now flash the ftf and wait till it prepares the files for flashing (believe me this WILL take a while)
5. Now when it asks to connect after preparing, switch off the device and connect by pressing the volume down button
6. Now it starts! Solved?
Press THANKS if I helped!

Thank you for that guide

I followed your steps but the same happens, phone disconnects from flashmode to boot normally. I even tried using a Windows 7 pc but same issue.
However, if I use SUS phone remains connected and the process runs well. If i connect with flashtool (or without any programme at all) it will disconnect after some seconds,

smash_07 install pc companion and go through the steps for doing a software repair it will install the drivers, as the drivers dont always install properly from the flashtool drivers folder even though it says there installed, once the s1 boot drivers have installed cancel the software repair and then open flashtool and go through the normal steps and you should find it'll start flashing the software for you, as I had problems like you until I did what I posted, also make sure there is no other sony apps running as that can stop the flash from starting.

Confused, it is normal that it gets disconnected after some time but it is so peculiar that it disconnects so fast! Try the solution posted by the other guy and share the solution, ll figure out another way if it fails

Ps: Before starting flashtool make sure that adb isn't running. Open task manager in windows, kill adb.exe if present and then open flashtool, follow the guide I posted earlier and when the part comes that the preparation of files is complete and when you connect your device, make sure that none of sony related apps are running (sus, pcc, emma). If they do, EXIT them first (closing them will minimise them to system tray so exit them from there). This also can be done before opening flashtool.

I did all you suggested but in the end i get always the same result, phone disconnects from flashboot shortly after connecting, eccept inside Sony Update Service or PC Companion.

I unistalled all the drivers, even Sony's apps a reinstalled PC companion to install the drivers again. I used another pc with Windows 7 32bits and I get the same behavior, disconnects from flashmode in about 30 seconds.

I'm starting to think that there's someting wrong with the phone itself, which i hope not.

Where do you see the percentage when flashing?

I made a tutorial on HOW TO FLASH STOCK ROMs WITH FLASHTOOL and I don't see the percentage. It justs tells me that flashing is complete.
