I can't get a signal - MDA, XDA, 1010 General

Hi,
Hopefully someone can help.
I got a XDA cheap and thought i'd have a tinker with it.
Now as far as i'm led to beleive it was working perfectly before i got it. The guy had been using it as his phone but wanted something smaller.
Now to the present time.
I have installed my O2(UK) PAYG sim card into it but i just can't get a signal from the machine whatsoever.
Now i contacted O2 to check if the handset was barred from the network and they have said that it wasn't.
I downloaded the latest RRU and radio stack updates from the O2 website and have installed them both successfully.
I have loaded the machine into the bootloader mode and it states that GSM is OK.
When i go into the options of the phone i can see the phone number but i can't do anything else. If i leave the phone turned for a while i eventually get a Sim card is invalid. Please contact your service provider for assistance.
Another thing i noticed was that the model numebr on the back of the XDA is NOT the same as the one given by the software. The IMEI numbers do match however.
Any one have any ideas??

Just to let you know i updated the radio stack to 6.24 and its now working perfectly.
Yee haa.

Mine does not get a signal
Is there anychance of posting the update you found
Pocket PC Wallaby PW10A1
ARM SA1110
O2 NETWORK

Don´t know if it is the same.....

Unlocked M3100 problems with O2 sim

Hi All,
Bought a SPV M3100 over a week ago (15th Aug) and got it unlocked using http://www.imei-check.co.uk/ straight away
Installed my O2 work sim in and had no problems recieving and making calls for over a week. However today I noticed the phone was just searching for an operator. Can not make or receive calls.
The original Orange sim works fine in the M3100 and so does my other O2 pay as you go sim. My work sim works fine in my other 2 nokia phones!
I have reset the phone both soft and hard
What is going on? Anyone have any ideas as i am very puzzled!
Thanks
BK
Just tried my work colleagues O2 sim which is just one number different to my phone number and the stupid thing is doing the same thing where it's just searching for a network!!!!!
Ahhhh. Someone please help.
My Pay as you go O2 sim works fine and for does the original O2 sim.
Thanks
BK
Panic over!!
Went into the phone network settings and changed the Network Selection to manual from Automatic. Then used the select button to choose "O2 - UK". The sim is now being recongnised and I have full reception again. Phew!
No idea why i suddenly have to do this out of the blue when it was working perfectly before.
BK
Oh Man! Just when I thought i had this thing sorted. It's failing to register on the O2 network again.
Anyone else having similar problems with unlocked SPV M3100's?

Please don't say this. My SPV M3100 will be here thursday.
I have my other pay as you go O2 sim in the m3100 at the moment and it working fine.
Therefore I am guessing the problem lies with my work contract O2 sim. I don't think it's tied in any way to the imei as I have tried the sim with multiple non work phones and it's fine.
I have read somewhere there may be issues with old 2g sim's i.e. 5 years old+ working in new 3g phones. I think mine was issued to me about 2000/2001.
Now all I need to do is workout how I am going to get the company I work for to issue me a new sim!

I had similar problem as you are. My M3100 wouldn't hold onto O2 signal. Not sure if its the phone, the Orange Rom, the O2 sim card, imei check unlocking or what. Solved it by flashing the Dopod rom works near flawlessly now. Can't guarantee it'll work for you but it did for me.
I give up.
Managed to get me a brand new O2 sim from work and............ it still does not work im my unlocked Orange SPV M3100!!!!
Whats so bizarre is my Pay As You Go O2 sim works fine and my original work sim worked initially for a few days.
Going to test my work sim in another 3G phone.
If its the sim then I will try and find out what needs switching on/off. Failing this then it's either going to be ebay or see if I have enough courage to try a rom upgrade.
ROM upgrading is actually very easy. All you need to do is download the desired rom. Connect the phone over wired usb activesync & then just start the rom program & its just a matter of following the on screen instructions from there.
What you will find that once the upgrading starts it'll get to 6% or something like that & then it will stop & display error messages. Don't worry just exit the program with disconnecting the phone (infact don't touch the phone at all) & start again. You'll go through all the same screens as before but this time the update should load till it finished. Takes a good 15mins so be patient.
I'm running the Dopod rom on my M3100 & everything is pretty stable.
Thanks for the advise Zen123
I have since my last post upgraded the Radio rom to 1.16.00.00
Touching wood with my fingers crossed and my lucky rabbits foot in my pocket I have a network coverage on my work O2 sim for 2 whole days!!!!!
The device has been reset several times and I use the Tube daily so signal is lost and gained frequently.
I am however still not yet completely convinced the issue is fixed as I believe I had network coverage for approx 4-5 days with O2 after I originally unlocked it.
I'll update this thread after a week or 2.

Hi,
just to prove you are not alone:
A guy i know using a Tango sim in Luxemburg bought an unlocked Vario II which worked fine with original T-Mobile sims as well as with his old prepaid Tango sim. But his new sim from Tango makes trouble as he can only receive calls but not call others.
Tango support assumed that new Roaming functions on the new sim caused conflicts with the Radio ROM which is 1.05.
He will make an update on 1.16 within the next days, I will report.

No GSM authentication with SiM card.

I know that you guys are very busy with Aku 3.x and Crosbow, but since my first Pocket PC Phone (XDA) never happened something like this with the GSM,so here I am:
-Last friday I was using my Tytn as always, after I sync my tytn with the exchange server, the signal of the GSM fell, at that moment I thought that the network of my carrier (Tim) was with weak signal. Later after many attempts it seems that mine SIM card cannot registered with GSM network.
-I placed the same sim card in another device and it works, after that I have tested another SIm card in my Tytn and worked (unfortunly it wasn't mine : now It seems that none Sim card is working, I've tryied several times search networks in manual mode , and everytime I found the networks "72410" (when should found "Tim" or "t-mobile", but cannot register!
Anyone suffered something similar?
tks in advance!
Phelipe
*I already upgraded the ROM1.35 and Radio 1.27
*The Radio is working perfect
Probably your phone has a net provider lock. Herm_Unlock_v2a.exe should fix this if you are running the unlocker's patched radio.
2 nights without sleep...
Pof ,
Tks for your reply.
Last night I used the www.imei-check.co.uk tool for my HTC Tytn. is this tool that you are talking about?
I´m using my hermes since November when I brought it from Amsterdam (Unlocked).
I had downgraded the Bl to 1.04 (I was 1.09)
Can you imagine why my carrier (TIM BRASIL) blocked my device or IMEI, suddenly ?

After use your suggestion it works again! Now I am afraid to upgrade my old 32k sim card for a new one,one amazing thing was the answer of TIM (my carrier) "They attribute difficulty to register because their networks are instable due the fact that Vivo (other CDMA2000 carrier) is testing GSM/HSPDA networks here in São Paulo (main city of Brazil).
Pof thanks again for your help. I´m a old user (but not so much active) of this forum, I will donate $5, and I will push harder my friend that works as Windows Mobile Director here in Brazil to give on copy of his WM6 compiled for Hermes...

No network problem - pls help

Yesterday, during a conversation the phone lost the gsm network. There is no way to connect again, i tryed with different sim's. My X7500 is not cid locked, installed ap4 weeks ago with radio 1.57 and it worked fine till yesterday. When i enter in manual mode to search available networks it shows the list but i can't access to it, failing to register to network. All the sim's are ok because they work with other phones and i can access the sim through sim manager normally. I tryed to install radio 1.50 but nothing, gone back to 1.57 but nothing again. Tryed to hard reset but nothing. Flashed to ap5 beta but nothing. I don't know what i should do. Does anyone have an idea?? I need my phone again... thank you
I Have same problem.

This is interesting. I bought my phone 14 months ago at Amazon.de in Germany and have regular invoice. Could it really be that someone have blacklistet my IMEI? Do you know where in Italy i can go to ask for it - mybe Police - before i send it to HTC service, i try to google. Thank you for the input.

First of all I will check the SIM. Just go to IL TELEFONINO store closest to you and ask for a SIM change. If the new one doesn't work too (and it works in another phone) , they will assist asking about TIM IMEI blacklist

I have a corporate Tim, working for a bank. I called 119 and they said that the Imei in not blacklistet, but they see just blacklistet Tim-branded-Imei. My x7500 is not branded at all. And my sim is working with other phones. In google i can't see any useful information.

Try putting another TIM SIM in your X7500 (from your colleagues will be the best, just to be sure). If this works... change the SIM card. If doesn't.. service

Yes i just tried, it doesn't work. Really think the only way is service....
But first i have to install orgininal German wm6 Rom and i have spl 3.5
If I have your situation, I will re-flash again and again same or different rom version.
Hope to clear some weak memory, same to radio rom as well.
With 3.5, make sure it is dead before hand-in. hehe

With "not TIM" ROM it works? If doesn't service is the only solution.
In this case ask to CMONEX, she can assist you in manually downgrading to 1.2 SPL
I can't believe it! I installed wm6 german rom for spl 3.5 installing again radio 1.50 and it's working! C'mon i just tryed radio 1.50 before.... maybe it's the combination wm6 and radio 1.50. can't understand this.
no not again. it worked for about 2 minutes. it's dead again
after flashing again and again and again .... working
thank you all for bringing ideas

A Problem That Has Foxed Even HTC!!!

Greetings Friends,
I have been using a HTC P3400( Old Gene) for last 2 years. As a member here of the Gene forum( although an infrequent one) i have been flashing the various ROMs made my many talented people here. Please bear with me if this post seems inordinately long but i want to share complete details of the problem i am facing.
My peculiar problem started when i flashed my Gene with Krazy_about_technology's ROM SumitsProUsers6.5_v2_OldGene.exe. After a couple of days of using it, my Gene would perenially be searching the network to connect to it, without any success. After numerous resets, hard resets, running ghost images etc and unable to resolve the problem, i thought this was an issue with my Vodafone SIM. I got it replaced and the problem still persisted. Post that i flashed the ROM with numerous other ROMs( Mostly Krazys, I find them very useful- Thanks Krazy for sharing your beautiful works), but the problem would just not resolve. The phone would always show searching a network to connect. I could not use SMS, EDGE or any other feature of my service provider.
The issue threw up another interesting find when i was experimenting with various other GSM SIMs. I used an Airtel SIM and the Gene would work good. Then i tried with a BPL Mobile SIM and it works just as good. But the minute i insert a Vodafone SIM, mine or others, it would indicate searching a network, I would not be able to make or receive calls or sms or access any other feature.
I took the handset to a Vodafone center and even they were flummoxed. They couldnt find a solution. They used my SIM card on different handsets and it works.
They thought my handset was somehow only disabling/ blocking only a Vodafone network. They advised me to get in touch with HTC helpline.
I called them and after lenghty discussions, they confirmed this was the first time they had come across such an issue. They asked me to visit their nearest service center. I did . The result was the same. Even the service centre was flummoxed and asked me to see what would happen if i downgraded to WM5.
I did just that with a HTC stock WM5 ROM provided by Vukile in the forums. and gradually upgraded to Krazy's WM 6.1 v 2.5
The problem still persists. I have been asked to visit the service centre once they run some tests or do some research on the problem themselves on a WM 6.1 ROM
In the meantime, I am currently using my Gene with an Airtel SIM and its working perfectly. It just wont accept a Vodafone network. I am using my Vodafone SIM in a Nokia handset.
Could it be an issue with the Radio ROM version? If so, why did it work with other ROMs and still works with Airtel and BPL mobile SIMs?
Is it really true that somehow, my Gene is only blocking Vodafone networks???
Needless to add, i am not a newbie to the world of Flashing and have learnt my way through friends in the forum like Munrus, Ababrekar, Vukile, NJackal, Chayn( He used to make some great ROMs) etc for the past 2 years.
This problem has completely perplexed me and all the techies i know.
I am posting this here in the hope that some brainy chaps might just be able to figure this out.
Thanks for reading the post and for any remedy you can send my way.
Rest assured, i will be keeping this post updated if the service centre is able to come up with a solution.
Cheers!
Ramon

SPL 1.10.Olip

Radio 2.71.90
Yes, there definately seems to be some issue with your Radio ROM. Its an older version anyways, mine is 2.79.90. Radio upgrading is simple, but finding the radio or dumping it from a phone is something i dont know.
I think the problem your phone is having is with one type of freqeuncy. In India, 3 frequencies are available : GSM900, GSM1800, and GSM1900. Most network use GSM1800 in most places and GSM900 in some places While Vodafone uses GSM900 in most places. I guess that is the reason why Vodafone sims are giving problem to you.
Two more things you can try are : If possible, using it in national roaming mode in some other state and Using some other number Vodafone sim. Try if it works. The site given below will give you an idea of what networks use what frequencies where :

Yes, You seem to be right. Vodafone at GSM900 in Mumbai seems the odd man out. Maybe the Radio ROM is not working for GSM 900 and hence affecting only Vodafone connections.
Still does it explain why the same Radio ROM worked for all this while over so many flashes and failed to connect to one particular frequency suddenly?
I have been trying to get a Radio ROM dump to 2.79.90 to upgrade. No luck yet.
My phone is out of warranty a long time ago. So no chance of getting the whole phone replaced without burning my pockets!!!
Thanks for your inputs Krazy!

Hi I dont think this is a problem with vodafone in mumbai...
Because I am also in mumbai using the vodafone service and also having the same (02.71.90) version of radio.
I think you have made any mistakes while upgrading...
Still check with upgrading Radio ... Let us know the status
Bhushan,
Yes , you may be right. Maybe i did make some mistake while flashing 6.5
None of the links have any Radio ROMs and i havent specifically done any Radio ROM upgrade myself. The only time the Radio ROM changed was when i ran Olipro HSPL.
Has anyone tried out railwayplatform's method?
How many of us are actually using the 2.71.90 version? If I am the only one facing this problem, then most probably the cause would be a bad flashing or M/B issue.
Cheers!
loop mobile a.k.a bpl mobile work on 900mhz so i dont think you have problem with 900mhz network as per my infomation your mobile is more then two year old so i think it time to buy new ..
Ofcourse its old!
But Loop and Airtel work flawlessly still. Its just Vodafone that doesnt.So no real reason why to invest in a new handset now.
Besides Its slowdown time guys!!!
There is a 99% chance there is nothing wrong with the handset.
So i am very keen to see if this problem can be resolved.
Cheers!
Hmm.. this is strange, really strange. Have you tried some other Vodafone sim too? Maybe its just with that particular number? I am just guessing now.
Krazy,
Yes the problem persists for all Vodafone SIMs( mine as well as others).
Have tried it with Vodafone SIMs of myself, my wife's, 3 colleagues at work and 3 at the Vodafone care shop.
This problem has been exihibited for all Vodafone SIMs.
Got a thought from a buddy - All this while i have been flashing with my SIM inside the phone. Does this have anything to do with the problem?
Cheers!
I dont think so...

i dont think so flashing with the SIM inside the phone is causing the problem...and may be you need to visit a HTC service center and ask them to flash an official wm 5 with an updated radio rom and see if it works...just a suggestion...Hope this helps....Good luck mate...
Just a thought
I have flashed my poor Gene and now departed Vox how many times I don't know, and everytime the SIM was inside. So that wont be issue.
Just a thought, are you using Vodafone Prepaid? Because Vodafone, atleast in Kolkata still provide 16 K SIMs and earlier when I had a Vodafone Prepaid number, my Vox would reboot between calls or while browsing the contacts / msgs. This was told to me by the tech support at a nearby Vodafone store that it IS a issue with all sophisticated sets (actually its sort of forcing you to go for a post paid where you will get a 32 K SIM ). So, if you are a prepaid customer, then can you try some one's post paid vodafone SIM and let us know?
Sorry! Duplicate post.
Yes 16 K SIM might be an issue because 16 K Airtel SIM is also creating problems like call drops, people call u but u dont get a notification etc.
I read the same on HTC touch orkut forum.
same prob here
dear friends,
i have also faced same problem, but a little differently.
I am a idea, punjab (formerly SPICE) customer. while roaming in ghaziabad / kale khan/ okhla I found that my phone lost network. it kept on searching on and on.i tried hard and soft resets also. if i did it manually, it wont register, and by any means it gets registered to a network, then 100% sure, call wont make. two sims showed this problem, one- idea and vodafone. but the problem was found while roaming only. i didnt report this in forum as i didnt take it seriously. but seeing this post, i decided to report it to forum so that it can be rectified. its just a feedback, not a complaint.
To Addicted2xda,
I am using a Vodafone Postpaid SIM. All the Vodafone SIMs i tried were post paid SIMs. At Vodafone Care, the guys there tried with a dummy SIM. The problem persisted for all SIMs.
This is really giving me sleepless nights.
Any way i can delete all the data on the phone including all ROMs, like bring it to a pristine state and then start with HSPL and flash a new ROM?? Maybe this may correct the problem - Just shooting in the dark.
To Mehra, Thanks for your feedback.
To HTCP3400,
I had a HTC STock WM5 ROM provided by Vukile. I tried it also. But the stock ROM didnt change the Radio ROM version and the problem existed with it too.
Cheers!
Guys, do you feel this could happen because of the SPL change? I dont know whether SPL is responsibile for sim activities or not, bu I will definately search for it. Apart from that, there is nothing we have changed in the phone. I dont know, but these kind of things never happened with me. Ya one or two times, my phone lost network at some places and keep searching for it even though other phones were working fine, but on soft reset or just turning the radio on and off from comm manager worked everytime. Anyways, lets see waht can be done.
Got this from htc touch orkut community

the problem has nothing to do with ur OS. Its linked with the Radio ROM.
Try diff versions of the Radio ROM which would go well with your network. For instance 3.21.90 rom solves the call drop issue on chennai airtel prepaid to an extent. So you ave gotta experiment with diff versions of radio rom n freeze on the one which would be better for ur network.
Hey vaibhav, can you post the Radio Roms that you have got. That would be good in case when one of us changes his network and gets this problem. Coz I searched for them but couldn''t find em anywhere.

Can anyone help? - No Signal

Hi folks, can anyone please help me with this problem?
My brother in law has asked me to look at his S740. He has tried several o2 SIM cards (UK) in this phone but always gets told there is no signal.
Not only that, but there is a symbol where the strength meter should be that isn't documented in the user guide.
He has also tried my o2 (3G) sim and a Vodafone sim, both UK.
Any advice gratefully recieved. We have tried several hard resets also.
Thanks
This means it's looking for signal. My guess: Still SIM-locked?

Not sure if it's SIM locked as there is a menu to select which carrier to use.
It reads the SIM correctly and sets it all up for o2, but just doesnt get any signal.
Does anyone know where the GSM antenna is on these? Maybe its a bad connection.
UPDATE:
I've had a mail back from HTC that recommends I send it in for repair, lol.
Now do I take it they are robbing buggers or do I take it that the icon is an indicator of a hardware fault??
Hmmmm, dilemma. lol
Are there any more suggestions on what it may be?
Has anyone successfully taken one of these apart?
it may be because of a hardware error...try to connect to a wifi network...if it impossible to find a wifi network then it is due to a harware problem.Most likely because the FR coaxial cable is out of its possision...download the service manual and see how to fix it.

Hi sasiskas, it conects fine to my wireless network at home. I take it from your response that the cable serves a double purpose.
I downloaded the service manual so I could take a look, but only got as far as removing the 4 screws at the back. lol, I couldn't figure out how to get it off, lol
I'm still stuck at the assumption that it is indeed SIM locked, and so will try to find a suitable card to try out.

Try contacting with your phone's provider (shop,e-bay seller whoever it is) and ask him details about the sim.Good luck.

Thanks. I have tried the same but just keep getting a vender ID, (lol spelling), error.
I would appreciate any input whether you have success or not, it just may spark an idea off.
I cant get in touch with any sales or provider as it was gifted to my bro in law. He's not that bothered about it but would like to have it working if he can.
Thanks folks.
Hey! I think I know the solution to your problem...I had exactly the same problem when I hardReseted my phone.
Go to "Start-settings-Phone-Band Select"
and then select
1.Network type : Auto
2.Band Type : "Euro" if you live in Europe, "US" if you live in USA , or "Japan" if you live in Japan.
Good luck...Let us know if it worked!

Yes that is a good suggestion because the phone will display that icon if it can't find a *usable* network, be it that the SIM doesn't allow it or if the bands don't match the selection on the phone or the bands are not usable by the phone hardware etc.
I would suggest downloading & running HTC Field Test (fieldtest.exe) with & without a SIM installed, with each network & band setting & see if it shows any towers or signal. (Normally you want Auto for both but you may not have that option or you might prefer to set to a KNOWN working band to conserve battery & minimize searching) If should show something even without SIM or with SIM lock because it's supposed to support emergency calls either way. If it shows signals with SIM but you still have same no service icon then it's likely SIM locked (although the phone should alert you to that fact) so odds are the phone hardware, rom or settings do not support whatever signals are available to you. (Btw if field test shows N/A for all the values you need to app unlock your phone)
Hope that helps.

can you share a link with HTC Field Test?Thnx
Search is your friend.

Hey all I'm having a very similar problem.
Had my HTC for some months now but in the past few days I've found that my network signal is becoming very unpredictable.
I'm also on O2 and I used to have a pretty contstant H (I presume HSDPA) connection.
Howeever im finding now the phone with go from H to 3G to GPRS to E to no signal in the course of 5 mines and round and round again!
Its very annoying as it means I cant make / received calls or texts fluently and even cut me off on a phone call too.
However usually on phone calls it will keep me connected ok till I hang up and then go to no signal.
I've checked the wireless and it is picking up networks..
Any other suggestions? I will try the field test tomorrow...
PS I know its not the network as my work blackberry is O2 and is not having this issue..
Cheers in advance!
Well, just to close my input on this thread.
I tried various ROM's available from this site and none worked.
I did try the band selection settings but still a no go.
I did have limited success but overall, nothing. The phone has now gone back to the person who asked me to look into it and to my knowledge he is going to sell it to one of these phone reclaim companies.
I did check and one place, I think through the post office, is offering £80 ish so not bad I suppose.
Anyway, thank you to all who have made suggestions and wotnot. Personally I'm still happy with an old Nokia 6300 and my Wizard (Mini-S)
Thanks folks.
