Sony x10 hanging or shutdown automaticly

You messed up your phone pretty bad.
It is time for you to Install a "Generic Firmware" on your phone.
(It takes some experience and knowledge though).
Watch JTAG mobiletech videos on youtube about how to Flash Xperia X10. You may visit XDA-Developers forum too.

#Try PC companion first
#Try SEUS second
#Try Flashtool at last

Be careful.. Don't do this if you're not sure what are you doing. You may brick(dead) your phone.

W810i flashes me a white screen then nothing

When I had the white screen problem, I was about to replace my W810i before I found out about the Sony Ericsson Update Service (SEUS). I used it to fix the firmware inside my phone, even though the phone seemed dead and my computer wouldn't recognize it. You can download the SEUS from Sony's website here:

Blank screen flashing on and off

I wouldn't call it a easy solution, but your phone is "bricked" anyway; you can attempt to re-flash the phone firmware which can be downloaded using the Sony Ericsson PC Suite.

Just run the "Update Service" application with you phone plugged into your computer using the connection cable.

90% chance your firmware is out of date and the application will attempt to flash your phone and return it to factory settings; you may loose contacts not stored on your SIM card.

If all goes well, your phone will be restored; the other alternative is to take it in for repair.

How would i update my SE z550i's firmware without a USB cable?

hi tech,

firstly: use the seus i.e the sony ericsson update service. its an online free update service by sony. its installation package comes with the phone, ona cd. connect your phone to the pc with the cable and run the soft after installing it. follow the instructions.

secondly: if u want to do it urself, then u ned some third party software like XS++, and some more files known as cust packs, main and fs. the mbn file is not the "firmware" but the "main " of the phone. so its not recommended to "flash" the software at home if u dont have the advanced knowledge about "flashing"... u may brick your phone. (make it permanentally damaged).

u may learn the flashing process from the site:

hope this will help!
