Polaris Radio problem solved!!

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.

I stand corrected, however I was referring to users who do not take advantage of 3G capabilities.

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.
goodlucks

Oh ok, now I understand the relation between the battery drain and GSM band selection mode. I will try it Thanks for sharing with us.

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!!

[Q] Updated FW to JM5, now phone is trying to access WCDMA

First off I've tried searching for a similar topic and couldn't find anything.
So here's my issue. I updated my SGS which I bought from a local O2 store here. Checked that is was indeed unlocked and went ahead to follow the instructions that can be seen here in the forums.
After installation, the language was set to an Eastern European locale, which conveniently was easy to change back to English.
I could not connect to any network, so did all the app installations via WiFi. It wasn't until early this morning when going to work that I noticed that I didn't have any DATA going through.
Checking on the settings, I now have the option to connect to CDMA networks, instead of the option to disable 3G (Only connect to 2G networks).
What do I do to get that option back?
Thanks in advance for your assistance.

You need to manually install your phone network details or AP (Access Point) details.
Firstly check you have any details entered.
Settings > Wireles and network > Mobile networks > Access Point Names
If you don't have any details in here then you need to find the information and put them manually in.
Other then this you can check your Network Mode the next entry below Access Point Names and select the mode you wish.
Mine is GSM/WCDMA auto.
Wish you luck with it.

That's the thing, there are APN's on there and all. It's just that the setting for 3G had now changed to CDMA. Is there a way to just flash the specific CSC and not affect the PDA & PHONE?

PDA must always be flashed. THe other two you can add if required.
WCDMA is the same thing just make the selection you want. No need to flash a different CSC. I'm using JM1 at present and it's WCDMA as it's from Europe but it doesn't effect the phones capability. It's just a name.

Thanks for the reply. So what you're saying is, even if it is saying WCDMA, it WILL connect to HSDPA? Flashing my phone now back to JM5. All other FW's I've tried just show WCDMA instead of 3G.

Eventually settled for JFF and 2G option is back. Now I have the problem of the APN's working. Off to weed through these forums again.
Different question, same problem unresolved. So my original problem is that I seem to have lost all data connectivity (apart from WiFi) after the very first FLASH. OH well. Thanks for your assistance Ancient_One.

WCDMA is not CDMA. It might be confusing a bit, but it's actually two different things. WCDMA is basically just another name for 3G.
(Well, it's a bit more complicated than that, but for the sake of simplicity, let's just leave it at that.)

Yes, WCDMA is 3G. It's not CDMA as used by Verizon and Sprint in the US (they just share some of the radio-level technology).

Thanks for clarifying the bits regarding WCDMA. My how things have changed. Anyway, I'm going back to JM5 and am hoping to get internet up and running. It is so annoying to not have everything working as they should, even after the APN's been added and all.
Much appreciated guys.

[Q] Defy, AT&T EDGE only

I have an unlocked Defy from T-Mobile USA that I'm using with my AT&T service, but I'm only getting EDGE wherever I go, no UMTS at all, and I've even heard of people getting it to run on HSPA bands. I know already that HSPA is available everywhere from my home to my workplace, thanks to my Atrix 4G. I've rooted the Defy and it's running Cyanogenmod 7 latest. Any help would be greatly appreciated, as I can find nothing on this forum or on Google to remedy the issue.

You should try to change the freq via baseband switcher.And restart.
Maybe you got the "2g only" checked in networks settings..uncheck that.
Settings >Wireless & networks > Mobile networks
You can also put automatic(2G and 3G) mode in GSM/UMTS network preferences.

Thanks for the reply Viper. I just noticed the baseband is set to some central Europe nonsense. Should I change it to one of the T-Mobile USA band settings? There's nothing there for AT&T.
Edit: I changed the baseband to US T-Mobile 3.Something, whichever was latest. 2G only was not checked. I'm still getting 2G only. Could it be my APN settings? Could I copy the APNs from my Atrix?

I'm having a problem with my AT&T connection as well, but I've been using my phone unlocked on the network since March with no problem. I'm new to modding, but OCD about streamlining my electronics. My friend suggested rooting my device and flashing a new ROM. I decided on stock Nordic Froyo, and it makes me so happy not to see all the T-mobile crap in my apps tray.
BUT the collateral damage is not so hot. I have no 3g or even 2g connection anymore. I tried the fix in this thread http://forum.xda-developers.com/showthread.php?t=944258 and was able to get a signal with 4 bars instead of the previous state of emergency calls only, but no letters like E or 3g and no ability to use the internet/transfer data. I also installed the broadband switcher in this thread http://forum.xda-developers.com/showthread.php?t=1052745 and tried all of the T-mobile US bands. No luck. I did rest the APN to default. No change. I've been using wifi, but will have to go back to work soon. Not having access to the smart part of my smartphone will feel sort of like having an arm cut off.
I'm not sure what to do next. I could try flashing another ROM, but from what I've read in the forums, that's no guarantee.
If anyone has any suggestions to help a noob, I'd be forever grateful.
Thanks in advance!

Thanks for the link, halah. Do I apply this as an update.zip from recovery? Or install?
Never mind, it won't work for me, for whatever reason.

[Q] Nexus 4 can't find AWS network

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?
https://play.google.com/store/apps/details?id=de.mangelow.network
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.

Band Setup Problem South America (select band GSM and UMTS menu)

Good day
I am currently in Venezuela and I just received a Moto X pure literally just get it out of the box. When I plug the SIM on the device recognized it I could receive SMS and Calls but no data, no 3G no H+, no 4g. I double checked the APN and nothing. So I look some Info and found this app from the store called "Network" which i think its just a shortcut to the *#*#numbers#*#* anyway below there was an option "lte/gsm/cdma auto (prl)" i change this to other options to try to force LTE but nothing worked. So going desperated press the three dots menu on top and click "select radio band" and by mistake selected USA Band. Inmediatly lost signal and now the decvice doesnt recognize the sim card anymore. I tried to go back to this menu (select radio band) but the only options i see are "USA Band Cellular and PCS" none of this working for me. I ll really appreciate any help you could bring me cause i dont have a phone to replace this one. I also ask the moderator to move this post if this is not the right place for it, I ve been seaching for help but there is just too much information concerning radios, modem, and bands that i can really understand.
My carrier here is Digitel working with this bands
LTE 1800
3G 900

Hopefully you unlocked the bootloader and made a backup before messing with such things. If not, factory reset is probably your best bet.

thanks for the reply
I just did a factory reset and still the same... could flashing a stock rom help with this?

Likely reflashing the firmware will put it back to where you originally had it. If it asks you for a password for anything, it should be all 0's (00000).
