W850i Flashing Screen

[merrymeet]

Hi Folks,

My W850i has started playing up...

Sometimes the phone boots up ok (especially if left for 24 hours without battery) but using the phone inevitably leads to it going into a flashing white screen. Sometimes it recovers to show the normal phone screen, but continued attempts to use the phone take it back to the flashing white screen, and eventually the phone just goes black and stops responding altogether. You then have to remove the battery to get any more life from it.

I have read around the WSOD (white screen of death), and thought perhaps the problem is firmware related. I tried the phone on SEUS (sony ericsson update service) and all it does is inform me that the pone has the latest software installed, it does not attempt to overwrite or update anything.

I then thought I would try XS++ to refresh the software on the phone - but I have no idea which version of the firmware to put on there...

XS++ gives me :

20:07:21| Baseband ID: 9900
20:07:21| Protocol Version: 3.1
20:07:21| Phone name detected!
20:07:21|
20:07:21| Profiling SEMC phone...
20:07:21| Platform: DB2020
20:07:21| OTP CID: 49
20:07:21| EROM CID: 49
20:07:21| EROM Color: Red
20:07:21| IMEI: 35282601xxxxxx
20:07:21| Phone ID: W850
20:07:21| Region: EUROPE_2
20:07:21| CDA: CDA102677/27 R8A
20:07:21| Firmware Version: R1ED001
20:07:21| EROM: R3A016
20:07:21| Ready for operation!
20:07:33| User chose NOT to update EROM CID!

XS++ offerred to update my CID to 52 which I declined because I have no idea what that means (and it says it cannot be undone!!!!)

Any advice on where to go next would be gratefully received.

Many Thanks,

Peter.

After looking closely at the XS++ info I decided to install W850_R1ED001_FS_EUROPE_2_RED49.fbn.

The Flash seamed to complete succesfully, switching the phone on now results in a couple of vibrations followed by a solid white screen being displayed.

At least it is consistent now
