Repair EROM K850i

[philzfog]

yes it has been water dameged buddie
try to rereflash it with out the lcd buddie as u need they keypad to start the flashing

[McBane]

Now I tried to reflash it without the lcd. But with Ultimate Unlocker and A2Uploader I get the same errors...

An hour ago I asked the seller of the phone (from eBay) concerning the water damage and he says that he is sure the phone never was droped into water. He only ask himself if the indicator could react on steam, because the phone sometimes lies on the window board in the kitchen...

[philzfog]

just show him the pics off the water marker and did it say in the listing it was water damge if not u can cliam ur monie back though paypal

[McBane]

Yeah, maybe you are right. I think we tried everything that was possible with my stuff.

Hey buddie!

I have news! After I put the parts together again I was able to flash it with A2Uploader and the Ultimate Unlocker wored, too.

But the didn't works correctly either. But its different now. Now sometimes it doesn't react and then another time it vibrates one time and the light of the keypad is on and the light round the cam too (I think it's called blue ring of death). And only one time, it showed me on the screen "sony ericsson" like it would like to boot now, but then after that screen it turned off again. So what should I do now? Now we have a different situation, didn't we?

try seus buddie see what its like after that if that doesnt work try reflashing it with difrnt main and fs (we will get this phone working haha)

[McBane]

OK I will try SEUS.

But before: The phone is now on, but it is for about 10 minutes at the same point. There it says "please wait". Is this normal? 10 minutes?

[philzfog]

a2 do take some time about 5 mins tops to load up take battry out then try to turn it on again

[McBane]

No, maybe you missunderstand or I do. I mean A2 is finished. Then I turned the phone on. Then "sony ericsson" appeared and then the dialog "please wait" appeared. That all happened on the phone. No A2 connected any more.

And now "please wait" is still there in the and it doesn't go ahead.
