Hi pupils,
I have a (I don't hope so) big problem. I wanted to use those flash menu in my Sony Ericsson K810i. This Mobile Phone had an T-Mobile branding and I wanted also to debrand this Firmware. Now after long time of searching the internet and with assistance of some guys of the internet I got the following files which I already used:

program:
SETool2 Lite v1.08

files:
directory:->K810_R1KG001
------------->k810_R1KG001_FS_EUROPE_2_RED52.fbn
------------->k810_R1KG001_MAIN_GENERIC_RED52.mbn
directory:->HB1-06_Gen_CDA102568_11_R8A_GENERIC_EUROPE_2
------------->zipped to file: tpa.zip

Ok how did I wanted to start the Flashing? I started SETool2 Lite v1.8 on Phone Type I choosed my K810. As Files I added the two files k810****.fbn and the k810****.mbn. I leaved the Firmaware upgrade pack empty and choose at the MISC files the tpa.zip. I also leaved the RESTORE file empty.

So I thougt it is now enough and I can start so I klicked on FLASH. Now the progam gaves me 30 seconds to hold "C" and connect my Mobile Phone.

Everything works fine and here is a log of the flashprocess:

So I removed for a short time the battery and put it back started my mobile phone without the sim card (the card and the stick was on the whole process not in the Phone as I read this before). The Mobile Phone works fine ... so far. I inserted the sim card and startet the Mobile Phone again and got a status bar and I thougt everthing is fine. I typed my PIN and the Mobile Phone asked me for an device code which I activated as I got the Mobile Phone. So I typed the password in but that was wrong so I typed the SE standard Code in which works fine.

And now here comes the problem :-). The Mobile Phone gives me a message, that the Configuration is wrong and I had to contact the Service-Center. So I started SETool again and klicked on Unlock/Repair and also that works fine but I still cannot use my Mobile Phone cause I got this message for an wrong Configuration what can I do now? I need help :(
