OK. Technically things are working now. Flashing the K700i did go OK, but ended up with "configuration error" and a practically dead phone. I still do not understand completely what I should do. My phone has a loader? with CID26. What i would like to do is upgrade the whole thing to CID 39. I do have the relevant MAIN file (K700_R2CA001_MAIN_EU_3_C_RED36.mbn) and the filesystem file (K700_R2CA001_FS_EU_3_RED36.fbn). No problem flashing the phone with these files, BUT: Apparently, I'am missing some elements, don't know which.
The firmware I would like in the phone is CID36 CDA1022298/42 "Generic Netherlands" the version is R2CA001 which appears to be the latest for K700i.
