Since a few weeks I have following issue with my O2 Trion:
Even though the antenna signal shows 100% strenght, I have 1 chance on 2 being unable either to make a call or to receive (same counts for SMS send/receive) When people call me, the call is forwarded directly to my voice mail like my telephone is shut of. When calling someone, I got 3X dong-dong sound without getting through
I have changed the SIM card , uninstalled a lot of applications but problem remains.
What other tests can I do to see if it is a soft or hardware problem?
The sof onboard is the original delivered on + pocketmechanic pro WM5 and Pocketmusic.
My O2 was originally German with QwertZ layout, got the 1.23.707.1 ROM, the radio version 1.06.00.10 and protocol 32.37.7010.01H.
Before I hand over my so precious tool, I wanted to know of some experts here have any suggestions?
Thanks upfront!
I've had several phones in the past that show maximum signal when actually they have virtually no signal at all!!
I wonder whether it's worth trying to limit the connection (as a test) to GSM band only, just in case you've got the band switching issue.
Start>settings>personal tab>phone>band and only selecting GSM in the drop down boxes.

Thanks, but I tried all options in those settings already. Auto + Auto, GSM +Auto, GSM + UMTS etc.. nothing seems to be stable. There is no rational behind to clarify this issue...
What i do notice is that when my network goes from GSM to UMTS depending of the strongest network, UMTS shows less issues( I believe)
I had similar radio problems with my German TyTN (E-Plus), that are resolved now that the device was replaced.
The E-Plus hotline confirmed there are some devices with unrepairable radio problems.
So before you or your callers go crazy with calls dropped by your TyTN or not being able to find a network or you're tired of the quick battery drain, the mediocre CPU performance or obscure crashes, get it replaced.
Would it help if I boot to another radio version only, or is it hardware related?
Issue is that O2 Trion is not supported / distributed in Taiwan (as all WM5are Chinese here)
Does someone knows if DOPOD would do the repair for a O2 XDA trion german version in another country than they distribute their devices?
Any hotline to ask?
Thanks
No, they probably won't. Upgrade the ROM, and flash the new radio. Read the wiki's and ASK FOR HELP before you do anything you are unsure of.
Follow these instructions to the letter and you'll be okay. http://forum.xda-developers.com/showthread.php?t=285586
Let me know if you have problems with the bootloader version
Good luck
I am entering this as a new post as I had a very hard time find this one and I think it's important. Also, I haven't been able to fix a replacement yet...

To my surprise I discovered that the Universal has 3 atennas for the GSM/UMTS Service (I don't know what is the purpose of each one), and my Jasjar is missing one of them!!!! :shock: And a conductive tape (are they really important???)
I couldn't believe it because my Jasjar was returned to warranty at Dubai, they changed the motherboard but they didn't realized that it was missing one antenna! Are they blind????? Maybe they are opening devices very cool with their sunglasses on 8) !!!!!!! :evil:
So I decided to make an antenna for it with the antenna of a Motorola phone I used, and my Jasjar worked perfectly with my past carrier (I haven't been able to cancel the contract so I am paying 2 contracts thanks to i-mate :evil: )
So my question is do anyone of you knows the purpose of each antenna?
What should I do, should I contact i-mate and tell them they are blind and that I will sew them because of all I have been through?
Thank you very much and I hope this time you will help me guys!
Here are the pictures:
DUDE!!! YOU ARE THE MAN!! People have been complaining about me not receiving calls, so I finally started to investigate and after a long search stumbled across this post!! I opened mine up and bingo, I am missing this antenna as well.
I'm going to try to fabricate a replacement and see if things go better. Someone ought to pin this post or put it somewhere obvious as this is a big find!!
Thanks again dude!
UPDATE:
OK... I've been trying to fabricate a new antenna using some sheet aluminum, but it is too flimsy to keep the contact. Also bloody hard to cut to the right size (took me four attempts) and finally succeeded size-wise after measuring with a micrometer.
Can anyone please suggest an alternative? Is there a place to get a replacement antenna with all 3 in place?
So, what do you all think guys?
Antenna Theory
I managed to make a more sturdy antenna using pop can metal. I ensured that the contacts were actually conductive and placed it in. However, I don't see a noticeable improvement in signal strength. It may just be an issue with the contacts though.
Could it be that the SPV M5000 was intentionally designed to omit one of the antenna's to discourage use on another provider's service??
May I suggest that the 3 antenna's are for EGSM (900), DCS1800 and PCS1900? Presumably, that would also explain the different sizes in the plates...I'd say the largest one is 900, the second largest is 1800 and the smallest is 1900.
The GSM mode sets EGSM and DCS1800 which are the modes I used. The second largest antenna is the one that appears to be missing. I'm going to try service on PCS1900, but I don't think my carrier uses it.
Still looking for an OEM antenna if anyone can direct me there.
UPDATE:
I have compared my mainboard to the picture in the service manual, and not only am I missing the antenna for DCS1800, but it appears that even the mainboard may be MISSING components to support the DCS1800 antenna! Can anyone comment on this? Where the picture in the service manual has little black dots which I presume are components, mine only has the gold connectors. This seems bad as this could basically mean that Orange phones are crippled to PCS1900 and EGSM(900).
Can anyone who is qualified please comment on this??
More Info
Ok, after getting more info on the provider, probing around in the phone and playing with settings, it ACTUALLY seems for MY case that I WAS using PCS1900. My provider uses 850 and 1900. I had always selected the setting for EGSM & DCS1800 and presumed that was the frequency actually being used. However, the EGSM for Orange is 900, not 850. SO, that must mean that despite the settings I had manually set, it must have been automagically switching to PCS1900 anyway.
That being said, I presume I must be getting poor signal in certain places because my phone can't roam to the 850 frequency when it loses the 1900 one and therefore just drops signal.
Now I'm on a hunt for a 850/1800/1900 OR 850/900/1800/1900 Universal.
Hope this post helps someone someday. It's been one heck of an adventure for me.
Since I took advantage of the orange ****-up and moved to O2, i just cant make phone calls from home.
From other places its fine, but at home its awful.
I have tried the O2 sim in another phone and its perfect, so I dont think its the phone masts.
I have spoken to O2 and they tell me the account is provisioned but unavailable to send my HTC the settings as they dont support the phone at all.
Is there anything I can do?
Sometimes it happens, you can always try a different radio. Some radios will improve reception in different areas. As an extra quirk, some can even improve battery life!
Take a look here for more info:
http://wiki.xda-developers.com/index.php?pagename=HTC_Blackstone_Radio
Just a word of caution however, you might want to get your HD Security unlocked first before flashing a new radio.
Can you list what ROM/loader/radio version you're using (I assume that you've unlocked an Orange handset)? Sometimes if you've got mixed up versions, the signal quality will suffer - see http://forum.xda-developers.com/showthread.php?t=557843 for someone with a similar problem after flashing their phone.
Different phones will always show some variation in connectivity; it's just a fact of life - but at most about 30% variation. If your other handset has 5 bars and the HD has one or zero, something is wrong with it. Also, since your handset is unlocked it might help to try a payg SIM from another operator (getting a free SIM is easy, and if you don't make calls it won't cost you to stick it in and look at the signal). We carry one from every operator, just in case we're stuck in a region with bad coverage and need to call someone urgently.
More info
I have tried a few different ROMs but currently using Duttys 6.5 R12 revised rom.
Radio is currently 1.14 but I have tried 1.16 in the past with no improvement.
My handset is unlocked (using the link on this forum).
In the other phone (an old Nokia) its perfect signal, 5 bars, but in the HD it ranges from 4 bars to none and all inbetween, quickly changing all the time too.
I might try and get hold of a PAYG O2 sim and see if thats any different.

Read through that and my bootloader screen is fine and shows SPL 1.56 Olinex security unlocked.
So I dont think thats the problem.
I have the same problem!
Got the HD yesterday, and reception goes from 0 to 4 bars all the time. When sim is in my other pdas it fine. I have an unlocked HD on o2.
My bootloader screen shows SPL-1.54.0000
Tried an orange sim and got 4 bars
Telephone connectin strength
I have the same problem.
At home impossible to call. On the road connection is regularly lost (when moving from one ground station to the next I suspect). This feels like the coverage problems in de mid 90s.
ROM 1.56.404.1
Radio 1.13.25.24
Provider Proximus
New sim did not help

19/10 I asked for a new sim card from my provider but that has made no difference.
I am having a problem with my HTC Touch P3450 phone for the past 2 weeks. Although the GSM signal looks good, I am not able to make/receive calls. I am on "Phone" mode (not Flight Mode or similar). Everything else (WiFi, programs etc.) works fine.
My operator is Turkcell and I live in Istanbul, Turkey. The phone was purchased from the United States.
I have done a ROM update to ROM version 1.17.707.2B WWE but the problem still exists.
Has anyone else experienced this kind of problem? I suspect that this issue has something to do with the 3G upgrading process going on in Turkey.
Can you try to use your friend's sim card and see whether it works.
Is it something like a dropped call?
I tried two different SIM cards, one with my operator and one with another operator. I am still having the same problem.
The problem is that I cannot make any calls at all, rather than dropped calls.
Also I cannot take any calls, when I call myself from another phone it goes to voice mail as if the phone is turned off.
I guess it is a hardware problem then.

I think its time to change your phone's radio. go to the elf-upgrading section to find out more.
I have the same problem
Hi, i have the same problem. When I make a soft-reset on my Elfin it has signal, but just 3 or more minutes after i cloud not make any calls and if someone try to call me they receive the message that my cellphone is off. Rigth now i am performing a radio upgrade and i will let you know if this is the solution for the problem, if you are done with this please let me know how to solve this.
Hi I have the same problem with this phone, can some one of you tell me witch is Radio ROM is the best for HTC ELF.
Thank you guys
I think that this is a common problem on Htc Touch, cause i have exactly the same problem.
I have this problem too
I upgraded new radio 3.34.90 but the problem still make me angry
Call ended itself, i tried 3 4 sims from 3 4 operator
Same problem.
i have same problem sometimes network gone automatically but signal shows full but after reset it starts perfect. thn after somtime same prob?
is thr any solution?
same problem here (P-3452 Elfin)
bsnl sim not working
Hello there.....
I am from Bangalore,India. i was using BSNL SIM for 2years. suddenly one day the Sim was dead. i thought sim problem so replaced 2 times after that got AIRTEL Sim. now its working fine. the problem is with 2 or 3 carrier operators. STRANGE!!!!!!!!
i have this problem too nobody to help pelease
tanx
please some one help me.....
I have been investigating this issue on and off for a few months now on one of my elf’s. I originally bought this phone off eBay to test stuff, and found no signal was being received when I got it. The auction did say this so fine. Checkmend says it is not blocked in any country, and is not stolen etc. Therefore, it is definitely something on the phone opposed to networks.
The phone can pick up signal, it noes networks exists, and can identify them, however, when registered and "connected" it does not pick up messages, and when I try to make a phone call the signal completely drops.
I like others have tried many roms. I have even tried every signal radio. I have also tried 6 different working Sims across a number of operators.
Basically, I think this issue is hardware, I mean, there really isn't anything else that I can think off. I have done some reading, and I *think* it may be down to the PA chips. There are 2 off these in the phone, one for Radio signal, and the other for Bluetooth, and wifi. (I think that is it).
These are located just above the battery on the back of the circuit board from what I can see, protected by 2 parts. One removable (two top screws - also contains the speaker) and one fixed into the middle part of the body.
I've done some playing, and it seems may be easy to break, either by dropping the phone, or even possibly by something as little as keeping the phone in a pocket and sitting on it.
I am not sure where I can go from here. I may need to investigate this further, but it is looking like it is going to be a dead end, considering I am not able to BGA solder to replace it, and expect the cost in doing so outweighs buying a new phone. I'm going to look into signal amplifiers, and see if I can find one that’s not just a piece of tin foil, and actually works. It will be interesting to see if that will improve the signal far enough for the phone to be usable once again. I may even just try with some kitchen foil, or by plugging in an external aerial (which I do not have yet, and may be costly, and therefore no point). If the external aerial works, I guess the chip could only be damaged, and not able to get enough strength itself.
This is only a theory on what I think is wrong with my Phone, and may be different to what everyone else’s is. But i thought I should put it out, to see if anyone else is able to confirm/kill my idea. It is a theory after all, they are made to be proven!
If anyone else has any ideas, feel free to pitch them, I like hearing what others are thinking, and it may be possible, although I admit very unlikely, that we could find a resolution to this issue!

@ashkan62 , can you provide a detailed problem please, this may give me something more to look at that I have missed.
wow. that's really informative. I've done upgrading radio roms too and even the spl. but nothing happened. hope your investigation on this works. thanks for the info.
or how about upgrading the o.s.? did someone tried that? coz I'm planning to upgrade my elf wm6.1 to wm6.5 and onyx 4 to onyx 6. would that work? what do you think?

I think it can't harm to try, be sure to follow the right procedure.
Yeah. I'll try to do the upgrade this week. I'll inform you if anything happens. (like bricking my phone. )
Hi, I bought a phone HD2 (EU version) and I have a problem with range on your phone, often lost mobile connection network, upload a new radio it did not work.
What could be the cause, and even if we can fix it?
Coverage on my HD2 is just as good as my N4 on the same network. Are you sure it's not your carrier or area that has poor coverage?
In another phone (same card) is functioning properly, the signal is full, but in my HTC lost signal in the same position

I too had same problem with my T-Mobile HD2, but googling on the problem I found out that if somehow you have dropped your mobile...it might be possible that the antenna contacts with the case of HD2 have been broken..
I opened up my HD2 (you can easily do it yourself, the GSM antenna is the one on the bottom near SIM card (its like two copper contacts ) , carefully twisted them a bit in upward direction so that it can again make contact with the HD2 case.
Assembled HD2 again. And there is no network problem since then.
You can also try this...(but make sure that its a hardware problem), if your HD2 is in warranty then go to the HTC service center.
