Xperia x10 "Unable to scan for networks"

[#1]

Hi, I have an xperia x10 on at&t (still only with android 1.6) and it has been working fine until a couple of days ago.  My wi-fi has been working fine (except for the occasional "unable to start wifi") until one day it just stopped working.  I was connected to my home wifi network when all of a sudden it just disconnected.  I proceeded to go into my settings to turn it back on, however, when I checked the box, it turned on for about 5 seconds then turned off and said "unable to scan for networks."  I have tried everything I can to get it back to working.  I have tried:

-Taking out the battery, sim, and memory card for a few minutes.  replacing them all and restarting the phone.

-doing the above but while everything is out holding the back key for 30 seconds, then putting everything back in and holding the power button for 10 seconds.

-Plugging the phone into my computer

The only thing I haven't done is the factory reset.  I do NOT want to do this because I have heard that it only sometimes works and if it doesn't work, then I cant't get any of my apps or anything back on my phone and it will be completely useless to me.  I do not want to lose all the data on my phone because I have no internet currently, and therefore can not backup anything.

Please provide me with some info that can fix this!

ok, turn off the phone, take the battery out, press the power button, put the battery back on, now make sure you first hold the back button and then without releasing it connect the microUSB cable to the phone. see if that works

i have usb debugging mode on.  would that make a difference?

[Uliwooly]

you can turn off your debugging mode

if that doesn't do it, we'll go on plan B

your first link does not work

[Uliwooly]

this might be something with either JAVA or your DeviceID

lets try JAVA first

go to

http://www.java.com/en/

and download java

[#10]

the java website says i have the latest version.  should i run SEUS in the background so that it stays in flash mode?

[Uliwooly]

to find your DeviceID

Run regedit.exe

and navigate to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\U SB\VID_0FCE&PID_ADDE.

You will see a number similar to this:

“1&23cfa456&7&8″.

This is your Device ID. Copy this number down

now go back to your folder and look for the DeviceID text file, open it, and replace what's in with what you just copy/paste
