sixt'th sense solusion :

Step by step

*** BA20 ***

1. FLash u r C45 with all34 205 with flx files until u r c45
Wrong Software

2. Read with logger 3.0 or 4.0 and make a map (with robot or
hardware dongle) use C45 type

3. Write map to u r phone, select c45 type first to read from u r
map and than change to SL45 type for Write IMEI... OK?

***end***

P.S. Read all old posts (in the beginnind of september) there was this solusion

Now I already got Wrong Software, so
I can skip step 1 right ?

Next problem is I'm not sure that map calulator program I used is work for my C45

Well, it's better to ask Sixt'th Sense for it, mayby yes or mayby not? Second question - yes - you need map calculator for calculate map - but in that way that it was written in solusion. Please read all old topics (page 2 or even 1 in the bottom) , I think that will help you.

P.S. keep on trying, I repered my C45 (but flash type was 4XX), completly dead (even no sound and display flash), so you can repeir too.
