Yes you can flash baseband, its safe! But I am on 157 baseband and on rom 108 without battery drain! Since no detailed changelog by oem about 157 I have no idea what is changed in 157 in diferencie with 108 and allso I am not interesing to 157 rom, used them 5 days and noticed 10 percent drainage over night which is not good. Now using good 108 rom. About dormancy, we can disable them totaly by replacing dormancy binary in bin folder with an fake script for example which we do "exit 0"... just idea! Disabling dormancy in etc folder in fd_custom_config have no sense since dormancy stil continue spaming logcat which mean is active (see logcat), its very agresive on 157 and I don't know why... Best idea is replacing binary.
