Seamonkey, thankyou for this. I was about to trade in my K800i when I got this problem. Actually I had no WSOD, no blinking infra red, nothing at all; it just wouldn't start… but this technique worked! I did however have to use the OLD WotanServer client, available from WotanServer's own site… do NOT go their parter FastGSM; they only offer the latest client which won't work for the K800, and credits between WotanServer and FastGSM are not transferrable. I learned this the hard way (but at least now I can unlock two Sony Ericsson phones if I'm ever foolish enough to buy them again).

so i thought all i had to do was switch it of and then back on then it would start playing coz that is usually the case.

when i tried to start it, it wouldnt work and i get 5-6 red blinking lights at the infra red.. took it to a shop but they couldnt fix it.

can some on help me out.
step by step i would really appreciate
thanx.
all let you know when the hammer optional starts looking aluring

On pwering up sometimes got sony screen, sometimes WSOD, sometimes got as far as enter pin. After trying this for ages the battery started to wear down and guess what it wouldnt charge the damn battery because the software was fried, so no phone no means of even charging it.

Took it O2/Sony – it was out of warranty, tool to a little mobile shop who said the memory would get cleared, i said OK, after 3 weeks of trying they couldnt reset it?????

Started searching internet and found a few useful posts but especially this one – but first problem battery needed to be charged – i had an old battery recharger the type used to charge AA batteries and hooked wires from the chargers terminals to the sony battery direct and fixed in place with electrical tape, the charger showed me when i got it right because a light came on to say battery was charging (the battery terminals on the sony battery are marked + and -, left overnight and presto battery had a full charge – now we can start.

I started to go down the wotanserver route (the payment put me off) then saw posts about SEUS and searched for that, not holding out much hope considering the professionals couldnt make my phone live.

I didnt realise at first that you fo NOT turn on the phone, simply hold the C key down after battery in.

I tried SEUS and didnt realise you are supposed to let go of the C key after it connects (it kinda flashed up quick as instruction 8 – my first few attempts i got to around 15%, and it failed. Then it wouldnt recognise the damn phone at all, so i tried holding the 2 + 5 key instead of C and guess what it saw it again? But this time it wouldnt load the software, then it would see the phone at all – arghhhhhhhhhhh!

I tried turning the phone on holding 2+5 – nothing, holding C nothing, noty holding anything and beep bopp it saw the phone, SEUS recognised it and started loading the software, but this time loaded 100%, and when restarting loaded new software hooray! but then froze at select phone mode – frustrating but i had a feeling it was going to come good.

Restared procedure all over again using C key as specified and whammo – i am back!

It can be done although the guy with the hammer solution i think is probably the best!
