Hi,
If your polaris having radio problem after flashing with any custom ROM (or even default) and setting the radio to Murata radio, then you can try the following solution.
The problem may include:
- you have strong GSM signal but you cannot make a call ( for example 1 success out of 10 trials)
- you cannot receive any call (dropping call) not on purpose.
- The battery power drains quickly (..few hours till a half day.)
- The GSM signal is not stabile (strong but kept frequently searching again for signal).
I have tried many ways, from flashing to original ROM and set to any Murata radios, but the problem still presists. Then I did the following.
1. Flash the polaris with any original ROM
2. Flash the polaris radio with the latest official radio version ( I just used the one that included with the official rom that I downloaded from http://www.htc.com/www/SupportDownload.aspx?p_id=59&cat=2&dl_id=113)
3. When the phone is ready, go to the setting, the phone, and then the service. From there you will have two questions, then select the first question, and choose GSM instead of auto, leave the second question intact i.e. "auto".
4. Your phone will reset its GSM connection, and then just wait. It will display "G" next to the reception bar. Then you can test by making a call or receiving a call.
5. If you still have problem, try to disable the HSPDA or any 3G services.
In my case I have T-mobile, where in Europe it is claimed to work perfectly. Learning from IPhone 3g problem in US, where Apple and T-Mobile tried to blame each other, and looking back to "poor HTC support" I could suspect that HTC has not provided the (old) Polaris with "the right" 3G driver.
I hope it helps. Let me know.

I'm sorry I do not quite understand here ...flash official ROM and official radio? then what? can I then flash any cooked ROM? or ported radio from other device? Thanks.
i have an official rom 1.40.466.1 WWE with Radio rom 1.58.25.21 and also i had this radio and low signal problem since i got the phone, never had a good signal at home.
tried to set the band in phone settings to GSM as you said not AUTO and it worked like a charm. thanks a lot
Hi Deepthroat,
I just did it with the official ROM, (ROM version 3.13.405.0 WWE, Radio version 1.59.42.15). However, some reactions confirm that it also works for any custom ROM and Murata-radio. Honestly, I have not tried to any other combination, just give it a try on your current configuration.
Thus, you can skip step 1 and step 2. Just minor correction on step 3, you go to Settings, choose Phone, and choose tab Band (not service as previously posted), choose "GSM" on the "Select your network type", and leave "Auto" for the "Select your GSM/UMTS band" and finally OK.
In my case, now I still have my polaris battery fairly full even after one day. Before the battery already dropped to 50% or less in after one day.
Please confirm if it works, you will save a lot of desperate polaris owners....
thanks
I can confirm the band tab change: network type from auto to gsm and gsm/umts to umts 900+1200 + gsm 900+1800 as a solution to battery drain and poor signal related problems as written on the first post.
I'm using gullum's latest rom TF2D III with the latest radio rom 1.59.44.02.
My reception is excellent, GPS works good and battery drain is not dreadful.
About the fact that 3G is letting the battery drain very quickly.
This is not a problem, but it's just the way 3G works. 3G just requires more battery power to function.

It means that we can't use HTC cruise/polaris for video call ??
I bought the polaris at vietnam and then I used it at Indonesia using Telkomsel as carrier. before I have bad signal also after upgraded the rom to the 6.1 it became good reception for GSM connection but when I need to use the 3G/HSDPA connection there is no signal. (using Band selection )
I already upgraded the RADIO to 1.59.44.02 and the problem still the same..
could anyone help to give info how to activate the 3g connection ?
thx

As I understood, Telkomsel Indonesia has a deal with Siemens to implement 3G/W-CDMA(or popular with UMTS) but not yet HSPDA (http://www.thejakartapost.com/news/...n-contract-set-3gwcdma-network-telkomsel.html). The 3G/ HSPDA allows networks based on UMTS to have higher data transfer speeds and capacity, however not all countries have implemented it (this is commonly termed as 3.5G network). So I guess in that case, you should set the band setting tab, Networktype to "GSM" and Select your GSM/UMTS band to the one suitable to your operator.
The problem with current polaris radio is that it is still not efficient to distinguish GSM and W-CDMA networks that leads to many side-problems (stability, quick battery drain, not working camera and etc). Though, I have not tried, some of friends claimed that polaris can support perfectly video call. So you have to work hard to find the right setting for your net. provider.

thanks for quick answer..
Actually I just want to use video call. Oh...very sad to hear that..
so do you think it's the polaris inherent problem that we can't do anything..?
I just try all setting..and I try also other operator like Indosat and proxl and the problem is same.
When I set the Band selection to W-CDMa or auto, sometimes After soft reset, polaris detect the 3G network but in 3 second dismiss and change to GSM network in most of the time just no signal.
everything is ok when I select the GSM only.
so no other option ?
thanks

If I were you, I will do the following:
Telkomsel requireshttp://www.telkomsel.com/web/info_3g, in Indonesian)
1. your phone is 3g (fulfilled by polaris)
2. You have registered to 3g service
3. You are in the area where 3g is supported
4. You have sufficient 3g signal.
In addition, Telkomsel uses 3G / UMTS / WCDMA / 2100 MHz. So if you have met the requirements, just set "GSM" and "GSM+UMTS 2100" in your polaris band tab (phone setting) and don't forget to enable the HSPDA in connection tab. If it does not work, reflash your radio rom to latest official release:1.59.42.15.
If it still does not work try to use 3g service in another supported handset (nokia or ericsson), if it works then it is the time to sell your polaris (just kidding!!!).
goodluck!!

Just tried this method and still am having horrid reception in Canada here under Rogers.
Can Australian users please tell me which radio rom they're using and whether they've had any problmes with the one they use?
I'm currently using "Radio 2.08.50.08_2" and the person on the other side of the phone seems to fade in and out, so i'm always asking them to repeat themselves...
When that happens, I look at the phone and there's almost full bars of reception.
I've also tried Radio "2.07.50.27_2" but that sems to do the same thing.
Thanks guys

hi anish.. fellow aussie!
i forgt to mention that i'm using Optus in Australia (using Dutty's 1.5 ROM)... i actually did try using the 2.05.51.11 when i first got the the fone... didnt actually notice any problems in that first day or two.
There's been so many newer versions since 2.05 and i'm hoping that someone has used a newer version and found it have no problems.
i'm just praying the problems i'm arent hardware-related

I'm on Telstra and haven't noticed any issues
Hey,
I'm a high user of the next G network and I'm using radio 2.08 and I have no issues whatsoever.
Using Radio 2.08.50.08_2 and Miri's Version 6 Xtralite ROM on an HD2 bought from Telstra
SIM is 3G Telstra
No issues whatsoever - a clean ROM without Telstra's marketing straight-jacket, all radio functions (GSM/GPRS/3G/BT/GPS/WiFi) work perfectly, battery consumption minimal, Telstra's Roam works perfectly in other countries
In short, the best PDA I've ever had ... I like Acer's S200 very much as well, but its' hardware cannot access the UMTS 850Mhz frequency that Telstra uses in regional areas of Aus - the Telstra HD2 is hardware-unblocked for this frequency, of course
bobb
Unfortunately your problems is a hardware one. To have maximum optus coverage on 3g you need 2100 and 900 frequencies
The Telstra HD2 works on 850 and 2100, so you lose the 900 coverage, and can only run off 2100.
To maximise coverage you would need a new phone, or switch to Telstra
FWIW I've found the 2.07.51.22_2 radio best onTelstra so far (using stock HTC 1.66 wwe ROM)
t9193 from telstra
ozrom 1.60 6.5.5
2.08 radio
hobart tas
no problems at all,actually got better with all the latest
good luck

Agreed, of course. If you purchased an HD2 from Telstra, it is hardware-filtered for UMTS 2100/850 Mhz. Optus broadcasts for 3G on UMTS 2100/900 Mhz, so Optus 3G will not work in regional areas on a Telstra-bought device - both devices will work on UMTS 2100 Mhz in the larger cities for 3G
That said, Telstra 3G area (distance) coverage at 850Mhz is very much larger than Optus 3G at 900Mhz
If you want an Optus 3G HD2, use an HD2 from (say) a UK supplier - this will be hardware-filtered for 2100/900 Mhz. For Optus, a cheaper (much) and equally powerful device is an Acer S200 from a UK dealer
None of this affects the GSM segment (normal phone conversations) of these devices
Email - through Telstra
I have no problems using Telstra and either stock or custom ROMs - except for emails.
For the life of me I can only send/receive emails when wi-fi is turned on.
It will NOT send/receive emails when wi-fi is turned off.
So I presume it is some settings.....
At the moment in Settings – connections – connection – advanced tab – select networks...
Telstra Internet (top pull down)
My Work Network (bottom pull down)
Any good suggestions ppl?
Cheers
FG
I use both Telstra and Vodafone in Oz and the best radio by far is 2.07.51.22_2.
No problem with email either way.

Telstra stock ROM forces you to use proxy, with Telstra stock ROM you cannot untick the proxy. Telstra proxy blocks email sync unless you pay $7 per month.
Use other ROM, go to comm manager, menu, connections, you'll see "Telstra internet" and "setup my proxy server", untick "this network uses a proxy..."
In my case email works after removing the proxy.

I'm using a Telstra version HD2 but on at&t 3G in the US. I am using radio 2.08.50.08_2 and haven't hadany issues at all.
Thanks guys
I forgot to mention that I tried switching the phone to 2G only before and the problem was still there.
I took into consideration the 850/900Mhz hardware issue at the time I bought the phone, but i wanted it so badly that i got the telstra one anyway because it's not often I venture into the regional areas where Optus operate their 3G 900Mhz system. Plus it was cheap on the telstra staff plan..
I flashed another ROM yesterday (Dutty's HG V1.2) that comes with the 2.08 radio - the problem didnt appear in any of the calls last night, so hopefully it's gone for good!
btw.. it's great to see other aussies on this board and their willingness to help out!
Nice to see people helping out. Yes the proxy thing is a problem so keep it unchecked

I think those that responded earlier were well-intentioned but your initial complaint had nothing to do with carrier frequency differences.
Personally - though I'm not in aus - I had horrible luck with the 2.08.50.08_2 radio, but much better with 2.08.50.05, which I am currently running.
If you look at the recent radios for our phone, you'll see some themes in the naming convention. Namely, 50., 51., and _2.
The 51 radios are NOT 512MB enabled, I know that for sure. I'm not positive on the exact difference between normal 50 and _2, but I know I get better performance, battery life, and audio quality with the 50!
In any case, that's my ramble, glad to hear you got it solved. If it comes back, just flash down to a different radio. Don't go before 2.06 if you're gonna use 'newer' ROMs, or your phone won't work!

I disagree with the " ... nothing to do with carrier frequency differences" section of your post
On the information supplied in the initial post, connecting to the internet for email transfer may well have been the underlying issue.
As it transpired, the poster doesn't much "venture" out of the city (predatory, carnivorous kangaroos, you know) so UMTS frequency in regional areas was not important
Most of the Roms I have tried(lots) all seem to have different radio bands available, I assume to suit the country/location of origin. My question is what Rom would be suitable for the GSM(900+1800)+UMTS(850+2100) which is what I believe to be the full Telstra spectrum. All the roms work OK but as I venture into the outback on a regular basis the NextG(UMTS850) is a must. The full Telstra spectrum is what I need to enable my best chances of reception. Without flashing roms is there a way to determine what bands/combinations are available as flashing is always a worrying process. If not can someone suggest a Rom? My reason for needing another suitable rom is due to locking limitations when another carriers sim is installed. I don't mean simlock but lockout of other providers data/sms and other services, limitation of band selection and others.
goldfinger, if I understand, are you looking at the band frequencies in phone settings and looking for a rom that has the complete Telstra combination GSM/UMTS on one line? My T8285 has Dutty's latest Holy Grail rom, but indeed there is no way to get that combination with one setting. Have you tried setting your Network type and Band Frequency to "Auto" and just let the phone find the appropriate signal strengths and settings for the area? Your phone is capable of that combination whether or not the rom has the correct combination as an option. Outside of the Telstra Rom, I haven't seen a rom with what you are looking for, or for that matter, what I would be looking for either, so I just keep it set on auto and it has never failed to get what I need.
The phone works fine on auto with most of the roms in the cities but without the full Telstra Spectrum there will always be limitations to receiving the strongest signal and as I mentioned I do a lot of fringe area driving so the NextG is important. The standard Telstra Rom Has the following band listings:
GSM(900+1800)+UMTS(2100)
GSM(1900)+UMTS(850)
GSM(900+1800+UMTS(850+2100)****
GSM(900+1800)+(UMTS(850)
The third band is the complete spectrum.
Where are the bands added in the roms?
I see what you're saying and unfortunately I don't think bands are added. It's just like you said, the roms used by the cooks are area specific because they are area specific releases by HTC. So, essentially it's out of our hands and up to HTC what band settings are included. Ideally, you would need a cooked rom using a Telstra based rom to get the frequencies you need. Now, I'm unsure if you can physically add the combination you need. Perhaps someone out there may know the answer to that. Are you still running the Telstra radio and rilphone, which if I recall I believe it was 1.10. I wish I could be more help to you.
The current Telstra Rom uses Radio 1.14.25.24 and I have also tried updating to 1.17.25.09 but this does not affect the bands at all. They appear to be rom specific as you said. Looks like I may have to learn how to dissassemble the Telstra Rom and cook my own rom with the correct bands. Hate all the telstra branding and limitations using the original rom. I think I better start reading.
Thanks for you help anyways Sean3.
TRY the secret code of *#*#2263#*#* ? This will work on tmobile’s samsung vibrant. This will allow you to check mark the 850mhz and 1900 mhz frequency for att 3g network. If you are on tmobile it will need 1700 AWS and 2100 MHZ for tmobile 3g. I would check all the frequencies so you won’t have to worry about this anymore. Let me know if that works for you. Thanks
this is questionable...seeing that you spelled enable wrong..
Instead of being sarcastic , why don't you just try it. I was trying to be helpful to the forum since i have received so much useful knowledge from all of you collectively . I stumbled on this by accident so i thought i would share it
Sorry, even though the menu choices are there, the hardware isn't. The vibrant does have the ability to use all the frequencies, but not the tab. I think samsung used one menu for every tab model.
Anyway the code is *#2263#. Keep trying -- we need a solution!
How one can dial *#2263# on T-Mobile tab, which doesn't have the dialer?

Heres what I don't get.. Why can't I select the 1700mhz band. When I do it selects the 900mhz band.
I am using Simple Mobile, so theres no way for Tmobile to block the IMEI number....
If I use a stock rom, it works 3g no problems.
The radio band is a limitation of the firmware on the device - the TMO devices are configured to only use the 1700/2100 AWS combination, while the AT&T variant is configured to use 850 or 1900. (Both also appear to work on the 2100 Euro frequency).
To change the available radio bands it appears that not only must we change the Android firmware & modem, but also we need to change the firmware for the RF amplifier chip which is sold by Infineon as being universal.
So far, nobody has figured out how to do this.
Hence we have the 2G limitation on the TMO tabs, and no way of switching between AT&T and TMO frequencies on the same tab.
The IMEI issue is a red herring that is only relevant if you are trying to use a regular TMO phone SIM from a normal TMO phone account in a Tab. They will not let you use a SIM from a standard phone account in your TAB because they want you to pay twice for the data - once for your phone, and again for the Tab. You can't simply drop your phone SIM into your tab whenever you want 3G data on your Tab. This is what they block by checking the IMEI number against your account type.

Samsung uses the same service menu for all models of the tab, so all possible frequencies are on the menu. If there were no differences between carrier models we would ask have the same model number. Different models, carriers, hardware.

I get that.. I come from the land of the HTC Leo. For a long time all we had was edge service, the RMNET 3g, then PPP 3g, then clockwork and finally true RMNET 3g. However, my thoughts are.. If the stock ROM comes with 3g service enabled, there has to be a way to suck out the guts that make it work. Also within our "phone" enabled roms there also has to be a way to split the data within the rom. Sorry if it makes sense to me but look at it like this.. Roto has a modem switcher, why couldn't we just code the rom while cooking to use one modem for data and the other for calls?
Just remember that no matter what device you are using, when on a phone call - Data does not work.
Please shed some light on the details I am missing..

Heres what I don't get.. Why can't I select the 1700mhz band. When I do it selects the 900mhz band.
I am using Simple Mobile, so theres no way for Tmobile to block the IMEI number....
If I use a stock rom, it works 3g no problems.

Wait a minute... Did you flash a Euro ROM over a US TMO Tab?
if so, you should be able to use the Roto Modem switcher that will allow you to use the TMO U S modem if you need 3G, or switch to the Euro modem to do calls and EDGE...
otherwise, something here does not ad up...

Roto actually tried to hack together the data code from the stock TMO 3G modem with the voice bits from the Euro one, but was not able to get it to work. Others have tried to flash modems from the Samsung Vibrant (which is in theory the same device in phone clothes), but the Vibrant modems will not play nice with the Tab and will not support 3G even with the US firmware...
There is something under the hood that we are not able to access that is blocking full phone capability on the TMO tab.

TRY the secret code of *#*#2263#*#* ? This will work on tmobile’s samsung vibrant. This will allow you to check mark the 850mhz and 1900 mhz frequency for att 3g network. If you are on tmobile it will need 1700 AWS and 2100 MHZ for tmobile 3g. I would check all the frequencies so you won’t have to worry about this anymore. Let me know if that works for you. Thanks

I agree with your approach. The modem.bin files we use with the modem switch both do what we want, but are excluding some hardware options.
My idea would be for someone to open the two binary files side-by-side to compare and find the line that turns on/off the voice in the 2g and 3g modems.
To that end we have a bounty thread in the general section, to attract the talent and skill we need. Why not go make a pledge? The higher the sooner!

I will try that in a few and report back. Good idea.
---ATTENTION ALL--- hey guys the only dialer pads are from the euro roms which uses a diff freq then north america we would need to make an american rom with tmobile or att united states 3g freq's this is why u can either hav 3g data or cellular serves also for u guys that hav cellular in order to hav 3g data you would hav to trash ur imei and make a new one tmous has all galaxy tab imei's locked for data only.... hoped this helped u all and we are out here lookin and waitin... GoodDay

according to roto, simple mobile uses tmobile infrastructure, so the speculation is that tmobile is still effectively blocking the imei.
I Have a brand new SIM from WIND mobile in Ontario that came in another phone. I have this Nexus 4 kicking around so I popped in the WIND sim, but it does not connect. When I go to search for mobile networks in settings, it finds all the non AWS carriers (including the 'WIND away' network) but does not show Wind 3G (this is what the correct network lists as on my phone supplied by them). I have played around a bit in the *#*#4636#*#* menu, but nothing seems to make it work. Is the AWS band disabled in some Nexus 4s, and is there a way to enable it?
Welcome to XDA
Okay, first of all to avoid duplicate threads please use the search function of XDA to find your answer, or do a little Googling...
Anyways to answer you question, the AWS band of the Nexus 4 is disabled by Google to lower costs. That may sound crazy, but the story goes something like this:
If you didn't already know, The Nexus 4 is based off of the LG Optimus G, and has a lot of the same insides...
The same board was used for the nexus 4 and Optimus G, and on some of the G models they had LTE on band 4 and 17.
The nexus 4 never went through the FCC for LTE so Google disabled it because it wasn't worth the trouble of supporting 1 band.
Now, your answer: Depending on the Android Version, it maybe as simple as tinkering with the Info menu you were in. (4.2.1)
Newer versions were harder to enable LTE
You need to figure out what you need to do depending on the newer version.
You may need something as simple as an older radio
You might need to unlock your phone's boot loader, (which requires a factory reset), or maybe even have to flash a custom recovery (like CWM or TWRP) and custom rom.
It would really help I knew more info about the device likel what Android version,if its rooted, or has an unlocked bootloader,etc.
If you don't know what any of this means DON'T WORRY, there is an entire community of people willing to help
Sorry I should have gone into more detail. I have done the various tricks to try to enable LTE, but is that the same as enabling the AWS network? I was under the impression from the WIND folks that the Nexus4 worked for them stock.
As for the firmware version, I have tried on 4.2, 4.2.2, KitKat (4.4 I think?). I have tried after flashing the stock roms of each of these versions as well as after rooting. I have also tried flashing different radio versions to no success.
I should also mention that under the "4636" menus I have tried to click "select radio band" from the menu, but this just crashes the process and goes back to the first menu.
So does no LTE mean no AWS?
Hmmm...
First of all, NEVER click Select Radio Band, like you said, it crashes both the menu and resets your connection. Bug? Unfinished feature? No one knows.
You are supposed to click on GSM/LTE button instead of WCDMA preferred.
If that sticks then you might be done on (4.2.1)
If on higher version, then get the older .33 or .27 radio or a hybrid radio
AWS is the band the nexus 4 has unofficial support for, so its actually the opposite:
No AWS=No LTE
So try getting 4.2.1 via factory images and try getting that working okay (WCDMA→GSM/LTE)?
If not then tell me
How about 4.2 (JOP40C)? I have that currently but I can go back and get 4.2.1 if necessary.
And just to put the AWS/LTE bit to rest, can I have (on this or any other phone) AWS without LTE, or are they synonymous?
I am playing with it right now without the sim becaue it is busy in the other phone. When I switch to GSM/LTE AUTO, I find AT&T as well as the big three Canadian networks, but still don't see WIND. I did not see the AT&T on WCDMA, but its spotty near the border here anyways.

Sorry for the late reply but,
In 4.2 all you have to do is switch to GSM/LTE and switch to correct APN's in the phone settings
You can AWS on 3G as far as I know but it won't make a difference...
The only reason we are using AWS band for LTE is because its the only one the Nexus 4 can see.
As for the last paragraph what do you mean you cant see WIND? What do you mean by "seeing"?
Can you clarify?

Could you try this small app (should trigger the radio band select menu) to see what options do you have?

For the Wind Mobile AWS, you will need the WCDMA option. This is what Wind Mobile use, not LTE.
If you will be able to select the WCDMA option and still no Wind 3G/HSPA, then we will tinker with the APN settings.

By 'seeing' I mean when I go to the network selection / search function in settings. When I click to search for network providers, I do not see WIND3G as an option (or any WIND branded network). On the phone they provided me, when I search for networks I have several options that are labelled as WIND. If I recall correctly, I think I have about 12 choices between various providers, whereas with the Nexus 4 I just show three selections.
@DupleX01, Thanks. I will give that a shot when I get a few minutes to play with this at home. It has been a couple of weeks since I have worked with the Nexus.

It's a slow day at work, so I am back on this. I have tried setting the radio to WCDMA only, but this does not make a difference. The only network I can see with the SIM in is "WIND away", which I believe is Rogers. So I am on roaming. Should I flash a different radio to the phone? Anybody got suggestions on which radio is the best version for use on WIND?
With the SIM in, the APN settings are already correct for WIND, but I am not finding their network.
Also just for kicks I flashed kitkat (stock) again, including the radio that comes with the ZIP. No changes in network availability.. Gonna leave it on this for now unless someone suggests that it might be better to revert to 4.2.1 or another version.

Based on your findings, I would say everything is alright on hardware side (APN is good, radio ok for WCDMA). So, it could be a glitch with Wind micro sim card. Still bonded to the previous phone IMEI what not. Make sure you now the serial of the micro sim, your imei of the new phone and give them (Wind Mobile tech support) a call.
