if you have 4 bars in 2G mode, then nothing is wrong with your reception level. 3G mode is completely different from 2G mode all together. having 2-3 bars in 3G mode is perfectly normal. 3G coverage is week in general. You have nothing to be concerned about really.

In my situation I was having 1-2 bars in 2G mode and 1-2 bars in 3G mode. (Polaris). Also, in 3G mode signal frequently was degrated to the level where radio would automatically fallback to 2G mode and stay there. We have practicaly entire HTC range at our disposal. Every single HTC phone that has been manufactured Himalaya inclusive. As soon as I have noticed week GSM signal on Polaris, I have checked few others for the same issue, namely:

Kaiser, Wings, Niki, Excalibur, Cavalier, Himalaya, Pharos, Hermes, Trinity, VOX, Herald and few others.

Also, please note: Kaiser, Wings, Niki and Polaris were running indentical radio: stock standard 1.58.21.23. we keep our handsets consistent accross the board as much as we can.

Kaiser, Niki and Wings produced excellent reception quality results with full 3-4 bars in 2G and 3+ bars in 3G mode.(UMTS 2100 and HSDPA).
I have tested on 3 GSM networks in total.

At the same time, Polaris demonstrated very concerning results in both 2G and 3G mode. (see above).

That is why I have decided to further investigate this issue.

After flashing Murata PPAS radio, Polaris receives 3-4 bars in GSM mode indoors, full 4 bars outdoors, 3 bars indoors and 3-4 bars outdoors. This is perfectly in line with other phones based on the same hardware platform: Kaiser, Niki and Wings.

I hope it helps.

P.S. At this stage I come to conclusion that there are Polaris handsets that have issue and others that have not. No matter what radio they being flashed to. This is perfectly possible if manufacturer replaced some electronic chip in newer batches of phones. This is common practice for mass production. Therefore we have conflicting reports in both polls.

bottom line is: if your Polaris has no issues with GSM reception after non-Murta radio upgrade, then it will likely to keep good reception level with any radio.
Murata radio seems to address the issue with support for specific chip only in handset and will not improve reception level for every single Polaris out there.
Please accept my appologies for such a long winded post.

I am currently a little too anxious to try out myself with my Orbit 2 but I thought it would be an idea to point this possible solution in a separate thread and for those who have tried it, please vote so we have a better overview if this is a fix or not... [edit] I tried the Radio-only first (after I did the HardSPL flash) but I still get only 2 bars 3G signal strength. Only outdoors it's 4 bars and when walking it's changing between 3 and 4 bars. 2G (GSM) is always at 4 bars inside and outside. After that I flashed the complete Russian ROM but everything stays the same. Also after hardresetting the device. Even after flashing it again and again :| Now I think I tried every option which I found on this xda forums several times... maybe any1 has another idea?

No need for apologies well it gives me a better feeling that my Orbit2 is not really that bad, though I remember I had better reception in original state. Currently I'm trying to figure out why TomTom does not get any satellites. I have updated latest data with QuickGPS and chose Built-In GPS...

[edit]

took about half an hour to get the initial first gps fix... but from then on, it gets the first fix within 3-5 seconds... nice

Works greaaat ! Thank you so much guys!!

Ok here is my story... I bought a Cruise but the first thing I did was to unlock it (without testing it before!). So when I tried it I thought "what this piece of shit... the reception is so bad!!" but thought it was normal so I was already thinking about selling it on eBay Then I found this forum....

I've just flashed it with Radio_Murata_PPAS_1.58.21.23 and it works like a charm now, so thank you very much!

ps: before finding this post I tried each rom radio I found! thx again!

You guys are great! I flashed the radio only Murata, and it fixed everything.

I'm an US expat working in China. The entire import industry for the Polaris shutdown these few weeks because of this problem. There will be many happy Chinese HTC dealers tomorrow. Wooohooo!

Hearty, hearty thanks!!!!!

Yeah I extensively tested my Orbit 2 this weekend. I think I have no more problems now with it. So my vote to my own poll is actually wrong now... should be "... my 3G reception is back to normal and at full strength"

Thanks to everyone involved on Xda Dev!

At home with original rom I had 2 bars, after to Raramomo SFR and 1.64.08.21
still 2/1 bars in 3G, I have tested Murata and always 2/1 bars, so I have decided to keep 1.64.02.21 because I known its battery's drain and I known nothing about Murata.

Thanks a lot for you works
