[Q] North America 3G reception problem after updating ROM to 3.4.2.145-003 Finland

[cheena]

I have a US Defy. I flashed it from T-Mobile US 2.51 ROM to 3.4.2.145-003 from Finland. I rooted and installed ItfunzBaseBandSwitcher.apk and switched the baseband to US frequencies. I am using the phone in Canada on Mobilicity (same frequencies as T-Mo USA).

Before flashing, I got 3G reception with 3Mb DL and 1Mb UL. After flashing, most of the time my phone shows H instead of 3G, and I get speeds of 1.6 DL 0.7 UL. I set the phone to use 3G only. Any other settings I need to check? Is it possible that other tools that change the baseband would improve the reception? Thanks.

I tried these 3G fixes since they were taken specifically from Froyo ROMs (I wasn't sure if the Chinese app uses files from Eclair or Froyo). The network status indicator still hovers between "3G" and "H". I have never seen "H" on my previous ROM, (US 2.5.1) only "3G", but I think the "H" it is also 3G mode (Maybe HSPA?). I'm on a 3G only network. When I set the phone to use 2G only, I have no network at all (no voice and no data), so that's why I'm assuming that the "H" indicator is also 3G. I don't know if that's because it's 3.4.2 ROM or because it's from a different country. Can anyone verify that?


The data speed in "H" mode is 1.6DL and in "3G" mode 0.6DL. Still not as good as with 2.51 ROM
