[Q] changing modem xperia z1

Makaze33 said:

hi, i have a z1 branded by h3g (italy) but i unbranded it to receive the newest builds; the problem is that the stock rom modified by the operator had a different modem to function better with their signal (i know this beacause other people with other phones had the same problem but, for example, they solved it flashing the modem via odin in case of a galaxy) and now, with the unbranded modem, the signal is really weak.
i have a backup of the stock ftf and can i flash just the baseband (i think that the modem is the baseband [?])? i just tried it via flashtool but it seems it didn't work... thanks to all and sorry for my english :silly: :fingers-crossed:
