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. :)


Hi guys,

I stumbled across this thread (http://forum.xda-developers.com/showthread.php?t=388823)... and it seems that there are already a few people who tried to flash the Russian ROM and after that flushing a WWE ROM without radio and they reported that their Polaris was working again after that...

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?

[mavvy4ever]

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

[BICKLARS]

Hi guys, i flashed the radio "Radio_Murata_PPAS_1.58.21.23.rar" and since its back to full strength!

i also lost all my data cuz updating the radio also hard resets ur device;-)good luck folks and dont throw ur polaris away!

[Robin_]

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 :D 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!

[harmsuploe]

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!

[LIPA]

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

[nl2006]

Murata radio is a life saver for wm6.1..awesome full 4 bars reception...highly recemmended for anyone have reception problems after updated their radio ..awesome :D

[SecureGSM]

Just to clarify on this issue with low reception for some Polaris handsets:

Manufacturer has replaced some micro electronic components in some batches of Polaris.

Stock standard radio 1.58.21.23 and others has no support for those new components and therefore new handsets suffer low reception level issue.

1.58.21.23 radio Murata has support for new components included and maintains backward compatibility to earlier shipped handsets.

this radio will not affect ( improve or otherwise) reception quality for phones in older batches.


P.S. Radio is genuine.

[ycimpir]

Thank you VERY VERY VERY MUCH guys :)

My Polaris was born again :D

1.58.21.23 radio Murata has support for new components included and maintains backward compatibility to earlier shipped handsets.

So all new radios should be reconstructed from begining with these or similar settings?

Great news, but too bad my dealer hadn't heard about it when I picked mine up. Can you please point to where you downloaded that rom and what you used to flash it? I tried the first of the two links above and the RUU is unreadable (??????)...

Thanks.

[schaggo]

Stock standard radio 1.58.21.23 and others has no support for those new components and therefore new handsets suffer low reception level issue.

My question is, why my (I got it early, I guess I have an old model) Polaris came shipped with 1.58.23.21 where the Murata Radio reads version number 1.58.21.23 which is lower and thus I assume older?

I think you are incorrect, I had other radio work on my polaris for little while in 3g before they dont work, I think it is got something to do with mty

[shumilica]

Thank you for the great discovery. This Murata thing is working! I wanted to go with this device to the warranty, but i said to give this a shot, because my TC had the same simptoms discribed (only that i tested in GSM, i use 3g only for net).
Where i had signal between 70-80% (2-3 lines) now i have 100% (i use this percentage because i have batterystatus program (http://forum.xda-developers.com/showthread.php?t=270751) that tells me in percentage). Where one hour ago my TC didn't discover any signal now it has 70% (2-3 lines).
I tested with dslreports.com/mspeed before and after:
GSM/GPRS: 29kbits before - 40kbits after
3g: 141kbits before - 200kbits after


My device information:
ROM VERSION: 1.25.405.1 WWE
ROM dare: 12/11/07
Radio Version: 1.58.21.23 (it writes the SAME version i had before, no murata no nothing)
Protocol version: 25.65.30.04W

I have to mention one thing: on my box (the box with the htc touch cruise in it), where it has the bar code, it writes Rev. A (from Revision A). I think maybe all devices with revision A will benefit from this radio and other revision not... please specify what it writes on your package.

Thanks again! Now I can say I am sattisfied with my investment (If you look in my posts I baught a s-h htc tytn I with battery drain problems... now is for sale for just 180 Euro in Romania... i can ship it if someone wants it)

[timat1981]

thanks you for your help.

I had a bad reception in GSM mode.

I downloaded this rom.

Now in my room my reception is full (after 2-3 lines).
And my touch cruise detect a 3g area (no before this radio rom).

I try in my office this morning (no signal with the original rom).

I'am enjoy and this Rom resolve my problem.

[yrsmart]

Hello, im also expiriencing same reception problems, but in my system alredy says that i have radio rom 1.58.21.23, the phone never got flashed, can be alredy the murato radio rom ?!
If not, can i try the murato radio rom with the "original" installed rom that came with de device ?

Anyone knows where can i get this current rom i have or maybe back it up if i want to roll it back ?

Some users expirienced some attery drains after flash with murato... what about you guys ?

Regards, Ricardo.

Regards, Ricardo.

did you buy "second-hand" so it might have been already used with a rom and been restored to "original" state before sold to you?

you can overwrite the rom even if it has the same version number.

i have no battery issues with the murata radio only rom.

[yrsmart]

Hello, no i bought the device brand new.

There is some way to back up current radio rom i have if i wanna roll back ?

To flash this radio rom will work in original pda rom 1.25.410.1 PTG ?

To do this operation do i need to run HardSPL or that is only intended for flashing PDA ROM ?

[shumilica]

yrsmart,
The murata radio looks the same in device information! It is a modified version (by an official company) of the 1.58.21.23 Radio! After you flash the murata radio in the device information you will see the same radio!
You can use customRUU (search and download from this site and put it in the folder where you extracted the murata radio and double click the customruu exe, not the one that came with the murata radio archive) so that you don't have to erase your current rom (only the radio rom will be rewritten), but backup all your data first and don't forget to hard-SPL first!!

later edit (after i saw your reply):

You don't need to change your OS ROM! You will change only the radio ROM using customRUU!
You need to hard-spl your device! If you think you will loose your warranty you can always go back to the original SPL (look here: http://forum.xda-developers.com/showpost.php?p=1962153&postcount=79 ), but look for your original OS ROM and original SPL first, so that you know you have it and keep it in your hard drive!
What device do you have htc touch cruise /xda?

[yrsmart]

Hi shumilica, i've found Hard-SPL-V2 , is with this that ill start ? This hard-sql will hard-reset my device ? What are the disavantages of using Hard-SPL ?
Thanks and regards.

[Edit]

I alredy downloaded Original SPL, do i need also my original rom ? Wasn't this only flash radio rom ?
I have a Cruise.

[shumilica]

I suggest you to read carrefully the sticky topics around polaris area.
Make sure you read this topic too: http://forum.xda-developers.com/showthread.php?t=381600
Hard-spl will not hard-reset your device, but please be patience, take 1-2 days to document and feel safe of what you are doing.
There is no disadvantage in using hard-spl (the only one was that you could't go back to the original spl for warranty purposes, but it is resolved now, check my post above). It is NECESSARY to hard-spl BEFORE any ROM flash (radio, os)!
Check here to see if there is your rom and download it: http://forum.xda-developers.com/showthread.php?t=373233

[yrsmart]

I alredy read the FAQ you said, but i can't find my current rom, but as only radio rom will be flashed there should't be a problem isnt it ?

[Edit]

Alredy updated raio rom to murata, flash was sucessfull, but i cant see if has really got murata raio rom because version showned is the same... Also i didnt get reception improvments... :(

[Steph92]

I had the same problem here in France (SFR), and Murata ROM radio solved the issue !

[reth]

Hi, Murata ROM is working fina but my only problem that I have is that language has changed automatically to Russian. Do you have any idea how can I chnage the language back to english? Many thanks, Reth

[shumilica]

You didn't document enough and you put the ROM for OS !!!AND!!! the rom for RADIO from the murata rom. You had to use CustomRUU to flash only the radio ROM. I explained some post ago in this thread how to do it.
You have to flash now a OS ROM (without the radio os). It is a topic in this sub-forum with ALL OS ROM available. take one from there and put it in your tc

[reth]

Thanks shumilica!! do you think we can continue this in Romanian :-)? here or forum mobilewave.ro..i'm sure io did something wrong and maybe you can guide me through..thanks (multumesc):)

[wheeliemonster]

I can confirm - O2 UK orbit 2 user, this helped me get reception back. Thanks so much...

Now 2 bars HSDPA in room where I had no reception, not even phonecall or sms...

Even the Radio ROM does Hard-reset your device though so just remember to back up first....!

[shumilica]

I will repeat myself untill I will have an entire page with posts that says:

You can do a radio rom flash without hard-reset only if you use CustomRUU.

[irreality]

Brand new HTC Touch Cruise (Polish language version)

Problem - very poor GSM/UMTS reception... in buildings one bar or nothing, outdoor 2-3 bars.

1. Hard-SPL-V2
2. Updated with Murata Radio ROM (Radio_Murata_PPAS_1.58.21.23) using Polaris_CustomRUU_v1.2

Now - FULL SIGNAL STRENGTH!

Thank you!

[amzchhabra]

So after only owning my Polaris (o2 UK Orbit 2) for 4 hours I decided to upgrade my rom to Bepe's 0.67 Opera and also update my radio to 1.64.08.21 as this is what I was using on my Kaiser and it was excellent with T-Mobile UK. As so many others the radio dropped all signal, and I was unable to use any sim with my phone.

Searching around, I found the Murata Radio which "appeared" to fix all of my problems in terms of reception, but I kept dropping calls, kept losing connection as soon as I called someone, and it got rather annoying...

I then stumbled across the Official o2 German update here: http://www.o2online.de/nw/support/downloads/software/xda/xdaorbit2/index.html

in which I noticed the Radio had been upgraded from the old German rom. Having flashed it to my Orbit 2, and then flashing Bepe 0.67 to my unit I have found the phone to behaving perfectly as it was before I started messing with it in the first place.

I would suggest anyone having issues with the Murata radio to try this although please be warned, it will return your device to a "Hard Reset" state, meaning make sure you have a backup of everything first...

[slavislavi]

I noticed something strange with internet connection (on all radios include murata).
Browsing internet is impossible without permanent pinging any host - all the time bands are still changing between H, 3G, E and GPRS.


- With permanent 'ping' all is OK and all the time I have HSDPA over 2000kbps.

- Without ping using internet is impossible :(

Anybody has noticed the same? Any solution?:confused:

[irreality]

I do not have such symptoms. HDSPA where available and switches to EDGE when signal gets too weak. When HDSPA is strong it stays at it.

[agpsexpert]

It works great on my Touch Cruise. Out of 4 different Radio ROMs I tried, this is the only one that works for me. Thanks a lot, you are a great help!! :)

[kogac001]

It works great on my Touch Cruise. Out of 4 different Radio ROMs I tried, this is the only one that works for me. Thanks a lot, you are a great help!! :)

Another Polaris has got his reception back...
Big thanks!

I wonder what would htc do without the communities that makes their phones usable...

[peekie]

for me it did not work :( signal outside on all my other phones is full but not on this phone

[Decaf]

I just flashed the new Murata radio and everything is ACE. Thanks for finding this out. I was so annoyed that I had screwed up my new PDA.

[Skyheartblue]

That's really great folks!!!
I'm visiting the UK right now and got to few cities that I didn't have any (0!!) reception what so ever. Which surprise me a lot!!
I then updated with the Radio posted here and MAGIC! I have 3G all over....

B4 updating I was running the latest released radio for Polaris.

Tnx again friends,

Hi,
thank you to give some ligth and extra coverage ;)
Now i had full HDSPA (4 bars) inside the building where before i only have 1 or 2, even another phone in "original" state has less coverage.

Had tried various radios on a friends O2 Orbit 2(UK):
1.58.21.23, 1.58.25.14, 1.64.08.21
All still reported a poor signal strength!
Just Murata Radio ROM, full signal!

Nice one! :)

[nutcracker2]

can I use radio murata on htc touch dual?
and how should I do that?

[Q2V]

Murata radio make a good GSM signal, but I found that Murata radio cause Bluetooth can't work.

Is anyone have a same bug?

[alroze]

No problem updating with Murata Radio ROM on a Polaris with french original ROM.
No 3G or 3G+ before, even outside
Now good signal, even 3G+ inside.
No hard reset (ouaou..) using Polaris_CustomRUU (http://forum.xda-developers.com/showthread.php?t=376119).
1 minute for HardSPL, then 3 minutes only for the Murata Radio ROM update.

Thank you helping me with this issue.

i tried flashing with murata radio but the progress bar stays at 0% for 10 mins and then it says error 262. Other radio roms work fine except murata rom.

Maybe I don't have murata chip in my polaris?

[banica.alex]

I am also using Murata Radio ROM: 1.58.21.23 on my Polaris and I must say I was really amazed about the very strong signal.

Great job!!!

[lazzy]

Tested both 1.58.21.23 and 1.58.25.14; but i find 21.23 more stable.

With 21.23, i get 2 bar for 3G. 25.14 also the same but it drops to 1 bar frequently.

Testing for both Radio ROM done at 1 spot which is on my computer table :)

[ahmetdamar]

Thank you very much. Best Solution. I installed "Radio_1.58.25.14_M.nbh" on my Bepe ROM. Signal is full.
Thanks again.:)

[khaf]

Suddenly it had happened; NO 3G nor GPRS data transmission. I can see the 3G sign , but when I make calls the phone disconnects; when somebody call me, he received a message that my phone is off line. Only when 3G signal is on. But when normal GSM is on, everything will be OK. My phone can not get data from the internet, even though it shows that is is connected. I tried all of the above solutions to fix this problem but no help. I tried to hard reset and try it before installing any software, no help. I tried mostly all available ROMs and Radio ROMs; even the original, but not fixed. I do not what to do. Now, I am using the phone with GSM only, NO 3G. Please help!!!:confused:

[White_Hair]

I have tried use the KaiserCustomRUU with the Murata radio rom to update the rom for my kaiser. The CustomRUU complained about invalid Model ID and the phone rebooted itself when the progress bar hit 5%. Can this rom be running on Kaiser?

I have the latest HardSPL (I believe it's 3.29)

Thanks :)

[Sayuuk]

Worked!

I flashed Radio_Murata_1.58.25.14 and my reception is full where I had only one bar before!!!

Thanks for this hint!

Works like a charm in my Touch Cruiser too. I flashed radio ROM from 1.64.08.21 to Murata 1.58.21.23 with Polaris_CustomRUU.exe (no need to hard reset). Now I have 3G and HSDPA working again, and internet connection is noticeable faster!

With this radio the hard reset will be done automaticly.All your data will be gone.

can i use Polaris_CustomRUU_v1.2 so ii does do the hard reset?????

[badguy999]

I am not sure.Triy it or wait for somebody to confirm.

[jungl1st]

can i use Polaris_CustomRUU_v1.2 so ii does do the hard reset?????

Yes U should use the polaris customRUU so it doesn't hard reset your device.
Just put the RUU_signed.nbh from the Murata radio folder to the CustomRUU folder.
Put your device in bootloader mode and run the Polaris customRUU.

The process does slow down at 99% , it's normal just keep waiting patiently until it gets to 100%

And you're done.

[jungl1st]

had a bad signal (1 bar) after upgrading to various radios roms, read carefully this thread and decided to give a try to Murata's radio and it did the job, I have 4 bars on nearly all time.

Tomtom 7 getting sats in no time...:D

[ZenkiMon]

[barbone]

I has the same problems, I find Radio Murata (http://wikisend.com/download/703338/Radio_Murata_1.58.25.14.zip), and everything is OK now.

Sorry for my bad english...

[Kenjari]

Flashing a new radio, doesnt affect the bluetooth at all right? I'm asking because, i'm having bluetooth problems...choppy....and i just want to find a fix for it.

EDIT: Well I flashed this radio and as far as signal...i didnt need much improvement in that. But, this bluetooth!!!!! I really hope that maybe its the headset. The problem is that I just switch from the x7501 Advantage...and the headset worked fine on that. No static, choppy, or nothing.

Can i install the HTC bluetooth fix on top of this radio?

[sonojo007]

After Unlocking my Cruiser I had the same problem as everyone; "no signal" and I flashed Murata radio and the signal is back but it is taking like 5 to 10 minutes to get the signal after every softreset. Is it normal? Has anyone having the same problem? Any solution?

[satyasatya]

I recently updated my ROM and after that the radio stopped working...However, Thanks to all the splendid people rolling out amazing softwares and helping the erookies like me, this Murata thing worked wonders and i got the reception back after 10 days of sulking !!! if any of the gurus of the xda-developers world are reading this, please know that i can't thank you guys enough. Cheers to all the effort that's put in on this portal !!!:):):):)

I am having a heck of a time trying to get 3G to work. I have tried both murata radio roms. It does give me good signal strength. That is not the problem. When I try to make a voice call or use data, it disconnects. The only way to use voice call and data is to actually disable 3G. Then everything works although its only through edge and GPRS. I've tried the original radio rom, some of the kaiser ported radio rom but they all give me the same problem. Interestingly, this all started about 2 weeks ago. Prior to that, 3G was working well in any cooked roms/radio rom combination. The only thing that changed was that I am now using a new SIM provided by my cell phone provider that came with my new 3G iphone. When I put this sim in the 3G iphone, I get 3G no problem. Could this be network related? I've tried the older sim card on my touch cruise and it gives the same problem. My touch cruise is revision A firmware as noted from the box. Do I need to send my touch cruise for repair?

I've the same problem, and also for me started about 3 weeks ago.
My SIM is a 128k Vodafone Italy ... i need to know if it is a network or a phone problem.

[rycckor]

To all who are having problems with 3G even after trying the Murata radio ROM, I have a few questions. When did the 3G started giving problems? What radio ROM/Cooked ROM were you using at the time it started giving problems? I am trying to narrow down the cause of 3G problems. It definitely is not due to a physical abuse. So it has to be a combination of software(ROM) and network problem. Please post your results. Thanks.

Thx, the signal has been annoying me for a long time. After I updated this Murata Radio, it worked out. Thanks very much. I'm now using uDk's R8 together with 1.58.25.14 Murada radio. It's amazing.

Hi everyone, i'm a brand new user of htc polaris (cruise in french) ans I have a terrible reception signal. I'va tried to download rom murata but it seems corrupted . Does anyone have a good link to download this radio rom ?
Thanks !

[pipaman]

This patch started a new life for my HTC. I really like all HTC Cruise features but hated the phone when trying to use it as it should work best: as a simple phone.

Now, it's working fine. Thank you!

Where did you find that ROM?

[maqui01]

Does it work with syrius r1 rom??
thanks, sorry if was asked previously

[koerc]

Hi,
read good things about the radio rom and want to solve my week 3G signal.
But is it compatible with official german O2 6.1 Rom ?

[deradam]

Hey all,

I have flashed my polaris with the official german rom from the HTC page (with Windows 6.1). Now I don't have any reception at all :( WTF? Can I use this radio rom for my HTC? (It is not an O2 rom like in the previous post, it is a official rom!)

Thanks for the very good work!
deradam

Update:
I couldn't wait for an answer and did it with this instructions: http://narawen.wordpress.com/2008/05/25/how-to-fix-poor-gsm-signal-reception-on-htc-touch-cruise-polaris/
Everything went well and *bam* 3 bars! Thanks very much!

Update2:
Ok, still very bad reception :( No reception in car at all. At home at most one bar. So all in all unacceptable :(

[cure4all]

[hugorfn]

what rom is the best work for radio murata ? prefence wwe or ptg?
thanks

[usmjan]

just bought used orbit2, sig quality was very poor--not more than 2 bars anywhere (no 3g in pakistan) or no sig at times or sig drops while talking. Murata radio saved me from returning back of phone; later on i performed hard SPL and flashed with original 6.1 ROM from xda---everything is fine now. There might be problems with higher versions of radios, original orbit2 radio is 1.59.42.15. This should work if you have reception problem

[silverwolf110]

the problem still exists and I only get weak 3G signal

[sdssss]

can someone please re upload the Murata radio version 1.58.21.23 for the Touch Cruise phone because many links posted in this forum are not working now
