Help. Blinking white light on K810i. What to do??

Need some help on how to fix my K810i.

I had a little accident one day on work so I missed my telephone on the floor.
this causes the LCD display to crack and only blinking white light came on.

I bought a new LCD screen to my telephone and works fine but now when I try to start telephone I only get this blinking white light. Nothing else.

Anyone knows how to fix this??....Somebody talking about a service cable. what is that?..Is that this USB cable called DCU-65??...

I have tried a couple of programs like SE tool and XX++ but I can't connect to the mobile phone..

So please help me anyone......

You need flash driver , read here: How to install usb flash driver - Top Sony Forums

Service cable is only for use with unlocking/flashing software.No, it`s not DCU-65 cable.
Tried with this guide step by step ( you must first install USB Flash Driver ). They are on this page:

Nice day

Yes I have now installed the flash driver. And it stands that the USB name of it is Sony Ericsson Device 116.

But when I try to connect to my telephone on XS++ nothing happening.
Cannot open phone communication port it stands.

I'm holding down "C" and everything as it stands...Telephone is blinking one time white light when I put cable inn.

Anyone has an idea??

Nice day

Ok. I have installed the Flash drivers and now XS++ is working so thanks a lot for that one.

But now I have some problems with the program allready.

1. How can I get the Main firmware??..I only have this Flash File Menu files that I've downloaded from this site.

2. After I have started flashing this File Menu. About 10seconds after my computer screen turns blue, and something about the USB is coming up an my Computer wants to restart. Anyone knows what this means??

I am running Windows Vista on my computer.

Look all files are in download section.

Here are:

Click on program and select properties.Then go to compatible mode ( run this program in compatible mode for windows xp ). Maybe will work this. If it works, then copy your log from xs++ here, otherwise tried setool lite.

Nice day

Thanks for the quick respond to my questions Jasmin.
I tried to set the Comability to Windows XP but still the same problem came.
So I downloaded SE tool Lite and tried that.

Read one of the articles you have written as "sticky" and Flashed my K810 without any problem. But still the same problem is there.

I downloaded the Main and FS firmware. Flashed the telephone with them.
And took out battery, Put it back after 5-10 seconds and started the phone.

Still there is just blinking light coming.
Telephone starts with one vibration...then it starts blinking slowly white.

Any more suggestions???

hey hey .. i am sure of this
while light blinking can be coz of GDFS problem or DUE to damaged phone screen !
my customers have experienced this .. ! goto service center and get it fixed

So it is not possible to fix this by myself??

This is last thing, that you can do, but I`m not sure, if it will help.

REPAIRING EROM GUIDES for most sonyericsson phones

Nice day

Hi there again...

I tried today resetting e EROM on my phone with SE 2 Lite.

I didn't understand excacly what to do but i think I managed it.
There was something about Resetting on the SETOOL that came up and that everything was executed. I think I did it right, but still the blinking white light is coming up..:(:(

I guess there is no other way than returning it to service shop then??

I think it`s better that you take it to service center.

Nice day

I will do that then. Hope it would not cost TOO much.
What will the service company do anyway??..
Anybody that knows that?...I mean, since there are no "physical" damage to the phone it most be something about this EROM or GDFS???...

And they have Special tools/programs to handle this??

if u not confirm what is the problem, goto service center is more secure for u. or else, the phone maybe cant on after u done anything wrong when u flash ur phone.
