Yesterday I’ve started the update process, getting a few ROM images from the Net and trying to make them work well with SoftBank. First, there was Aug,2010 version of Froyo ROM on MoDaCo, where Paul said he did not change anything except rooting the system. I’ve made a few changes in config files regarding SBM network settings and upgraded. Everything went fine, except the phone started to behave funny and today it even FC’ed its own Launcher (!). The version of ROM was 2.09.405.8 WWE.
Finally I gave up and downloaded official RUU with 2.29.405.5 WWE software. Extracted .zip file and applied all the same changes before flashing. The only difference was, I’ve decided to change
ro.wifi.hotspotUI=1 and see what happens. The results were interesting — I’ve got two extra menu items (1) in “Wireless and Networks” settings tab, which allow to setup and configure the wireless hot-spot and share internet connection wirelessly. Probably the cellular providers are not very happy with that, which resulted in these items being excluded away on most android phones.
Also, the interesting item was (2) “USB tethering”, allowing to convert the phone into RNDIS ethernet gadget and pour TCP/IP over USB link to the PC.
