after that but i can not see the output indicating that the phone is
updating the firmware.
I guess you have a self build seriel cable betweeen your phone and your
serial adapter? Check the cables in the plug, maybe they are too close,
so there could be a bypass.
May also check rx/tx, there are some serial adapters that mixed up the
description on the harware. Hope this is helpful.
