So what is wrong? What should I do to solve this problem(s)?
(The username and password are correct, because if I click on "Get Credit Information" it shows me the right information.)

whats up with ur erom ?

I only guess the problem is a kind of EROM BUG I already knew from the K800i I had. Because the phone doesn't start anymore. It only reacts if I connect it with holding 2&5 to the PC (Holding c-button doesn't work).

So I want to try to repair the erom. And the only program that may will work, seems to be Ultimate Unlocker, because of the DB3150.

what was up with the phone blue ring around the camra and the key pad lights only came on or nothing ?

No I can not see any blue ring or lights when I press the power button. The only signs of life I can see, are a red light at the power-button when I connect the phone to the PC and the reaction of the PC when I press 2&5 on the phone while connected with usb...

from that read out at the top it looks like ur battry could be the problem do u have any other se phones

Yes, I have a K800i and a W200i.

nar battrys to big some thing like w580 will do

No, there is only a K770. But at the moment it isn't there. So I have to wait. I now have connected the K850i to the charger. But with the charger the red light isn't on at the power botton...

do u have any smally screw drivers t5t4 to take the battry cover off it for a min
if so take it off carfully then push ur battry in but not all the way then plug ur battry charger in wiat 2 seconds then push ur battry in all the way

I'm afraid not at the moment. But I don't think the problem should be found there. Because the red light is on every time I connect to the PC. So I'm not sure if it should be on when charging?
(I don't know how the phone reacts correctly, cause I got the phone today the first time).

okies nps but do try a fully charged battry in it b4 doing any thing softwere wise to it could make it worse buddie do u have any other tools ie se tool box

Yeah I have SETool v0.914038, but I can't start it (because of this error: Severe error 8010001D program terminated), That could be cause I only have the software without the box....

yep u need the box buddie

That's why I'm trying to repair it with Ultimate Unlocker. But I get this errors I posted.
So, do you have a solution for this errors? Or do you know what they mean?

You can think about it some hours, cause I'm going to bed now :)
Thank yo for your answers till now. See you later ;)

I'm back again :)

So does anyone has a solution for my problem?

Please! Is no one able to help me? I payed 20 Euro for it and it didn't work. I would ask the support of Ultimate Unlocker, but I can't find the "USC" they want to know.

I will repeat the Error Log:

u need to get a fully charged battry buddie

The phone was all the night charging, so I think it should be fully loaded. There has to be another problem that produces that errors...

ur phone in the state it is wont charge the battry

Ok.
Now I found the K770i of my mom, with the same battery (fully charged) as the K850. So I tested it and it reacts the same way as with the old battery. It didn't start...
So we can be sure it isn't the battery that produces the error.

and u have tryed it on the sony ericsson update service

Yes I tried SEUS, but it said something like it can't find anything for my phone and at the same time it said I have already the newest software.

PS: I used the buttons 2&5. Because they are the only ones that work with the PC.

have a read though this then try to reflash it to see if it will take a flsh and see if u get any err when u do it
A2-DB3150 Flashing - Top Sony Forums

Yes I tried this already. But it didn't work. Because all these tools want you to hold the c-button. But with c-button my phone/pc doesn't react. And with 2&5 it says the following things:

Code:

---

ChipID:C802,EMP protocol:0401

can't get NET header
can't load ACCESS CPU preloader
Can't load ID loader !

can't get NET header
hardwere fault has the phone been droped or water damge
and were u plug ur cable in to ur phone are the gold pins clean

I don't know. I got it from eBay. But nobody said something of water damage or something else. The person only described that the phone sometimes works and somtimes can't get startet. So I thought it could be only a software damage and bought it (and hoped to repair it). The seller himself thought it could be a software damage, too.

r a ebay phone what couor are the markers on the battry and in side off the phone were the battry goes

I don't know exactly what you mean? Do you mean the colour of the contacts? They are both (on battery and inside the phone) gold.

next to the gold con there should be a white sticker that goes red when water damged

Ah I see. But the sticker is white like it should be, right? So no water damage or new battery?

maybe new battry buddie inside were u put the battry at the top is were the battry meets the phone contacks sholud be a other markers

The only thing I would identify as a sticker is white inside the phone. Or to say it in other words: There is nothing inside the phone which has the colour red. So that's a good sign, isn't it?

could be a have service manal posted on hear use that read it very carfully and if u have to open it up to see if u can see any hardwere faults like water damge

Sorry I didn't get this. Do you mean I should read the service manual of the K850? And then open the case to see if there is a water damage?

In this case: I opened the case already in the afternoon and can't find something that looks like a water damage (so far a noob like me can check/discover that). It looked all right for me, but a pro would maybe find out more...maybe I should post some pictures when the phone case is opened?

u can show a pic off the full pcb with out keypad or lcd and try to turn on with out keypad then with out lcd

That sounds difficult. I had removed in the afternoon the case and the keypad, but not the lcd, because i don't wanted to damage something. I hope I can remove the lcd without damage it.
I will try it tomorrow.

Till I will do that maybe we can go back to the topic itself. You don't know the meaning of those errors the ulltimate unlocker shows, do you? Maybe there is another solution we can concentrat on till tomorrow? Maybe I can ask the support of the Ultimate Unlocker concerning those errors, too? Do you know where I can get the USC I need to cantact them (Because they say you get a USC if you are bought credits. And in fact I did that.)?

did u pay on ur card or paypal if so give them the detail and the email u had the password sent to

I bought it on PayPal. But you can't send them something concerning support of the program if you don't type this usc. So I have to contact them in general (there you don't need an usc, because you should ask there only questions concerning questions you have before you use it. But I will try it in that way then...

Hello,

Now I made the pictures of my phone. I think I discovered the problem, which I didn't saw the first time, now. You can see it on picture F and G. There the sticker is red :(

Sorry for the bad quality, but my K800i was unable to focus the object correctly:

K850_A
K850_B
K850_C
K850_D
K850_E
K850_F
K850_G
K850_H


So I think it's a water damage.
Is there a chance to repair it, if the water doesn't damaged something?
