I've done something - no mobile signal HELP! - MDA, XDA, 1010 General

Hi, I've had my XDA wallaby for about 4 years now, no problems ever until tonight.
It's got the Rom 1.2 upgrade and I usually run a Tesco's O2 PAYG sim with never a problem.
I've got an Orange card that I wanted to use - this seems to have caused the problem.
I was looking through the forum to try to get the Orange sim to work and have, I think, re-set wrongly the GSM band and the autoconfiguration.
So now whichever of the 3 GSM bands I set my XDA won't recognise either the Tesco 02 Sim or the orange sim HELP??
Also, I've looked in the auto config list and neither appear, again HELP!!
Can anyone suggest the correct settings for tesco o2 since I'm stuck HELP

It's fixed itself! Weird. Read on...
So there I was, staring glumly at my number one piece of kit now w/o a telephone then all of a sudden, up comes the signal bars and the 'G' !!!
About 5 minutes after my last post.
So I guess the message here is:
1. leave well alone
2. write down EVERYTHING before you play, and
3. The XDA knows more about itself that me the user does, since it seems like 'it' fixed itself.
So back to the original issue that I got so badly wrong.
Q: Can I use an orange PAYG sim in this phone w/o killing it again?

And now it's dropped the connection again !!!
I know this must be my meddling but can anyone tell me the correct
autoconfig and band settings for O2 Tescos.
I've used this network as PAYG on my phone for about 2 years with no problems until yesterday ???
Or other than those 2 settings can any other settings influence connection, bearing in mind it used to work perfectly, and did for a few minutes last night???

status update - problem solved
I think I found out the problem.
When in the phone module, select:
Tools > Options > Network
Network selection needed to be Automatic but for some reason, probably my medelling it was set to manual and was taking about 5-10 minutes to find the connection.
Now, as auto it connects in seconds and then all is well.
The post might help others in the future.

[SOLVED] Cannot use GSM radio - help needed!

I have since discovered that my IMEI has been blocked. This phone was bought off eBay in January but apparently the block was only placed on August 7th. I'm gutted, I'm really hoping this can be resolved or that I am covered by insurance.
--------------------------------------------------------------------
Hi everyone,
I'd greatly appreciate any help anyone can give me. Here is what happened:
About 2 weeks ago I upgraded radio from 1.38 to 1.50, which worked and everything was fine.
Last week I went on holiday to a little place on the beach, where signal has normally been a problem. Not so this time, I had plenty of signal and was talking and texting fine.
On Tuesday it worked all morning and then in the afternoon the signal dropped off and it said "no service". I cycled the phone radio a few times and rebooted the phone, all to no avail. I concluded that the local cell tower had a fault and that I wasn't in range of another.
On Wednesday we took a trip and, as I expected, a few miles down the road my phone picked up signal again, consistent with the faulty cell tower hypothesis. I recieved a load of texts that had been waiting for me, made a few calls and everything was fine. When we got back to where we were staying, the signal held - I presumed the fault had been fixed.
Later that evening the signal dropped out again as before. I assumed that perhaps the fault hadn't been sufficiently fixed in the cell tower, so while annoying I presumed when I got to a different area the signal would come back like it did before.
However, it didn't. We came home on Friday and it hasn't picked up a signal, just says "no service". If I manually search for networks it finds O2 (as well as all the others) and I can select it, but it still says "no service".
I plugged in a T-Mobile sim, and it found signal immediately, BUT I cannot send/recieve calls or texts, people calling me hear a strange problem about it being unable to connect their call, and text message delivery reports give the same (not the message that one gets if the phone is switched off) - so it is obviously on the network but something is stopping it using the network - when I try and make a call I instantly get those four beeps which indicate the call has ended.
I then phoned O2 and said I think my SIM is dead, and they agreed and are sending me a new one. However, I then tried my old O2 sim again and got a brief signal, but still the same problem as the T-Mo sim - cannot send/recieve calls/texts/anything.
My O2 sim now says no service, although I have tried it in another phone and it works fine.
Since then I have re-flashed 1.38, hard reset the OS (Sleuth's v3) and flashed the O2 WM6 official rom with 1.47, all making no difference. I've tried forcing 2G and 3G and particular frequencies (it usually says it cannot apply these band settings, but after several reboots I sometimes manage to change it).
So, in summary:
Signal is very intermittent and usually says "no service".
Even when I do have signal, I cannot send/recieve calls/texts.
My O2 sim definitely works.
I have tried radios 1.50, 1.38 and 1.47 to no avail.
I have hard reset the ROM (Sleuth's v3) and flashed the O2 official ROM to no avail.
Desperate for help! Many thanks
I have also cleaned the SIM, SIM contacts in the phone, and checked that I can access the SIM card from the phone, and I can get the phone's IMEI etc so at least part of the radio seems to be working, and as mentioned before the SIM definitely works.
Thanks
Update:
I have tried Orange post-pay and Orange pre-pay sims and they both work fine, so it doesn't appear to be my phone that has broken.
However, my original O2 sim continues to work in another Nokia phone, suggesting that the sim isn't broken.
It may just be the pairing of that sim with my phone, which is the only thing I can think of. Does the Hermes apply sim "profiles" to sims which are inserted? Have I messed up the profile associated with that sim? My new O2 sim should come next week so we will see if that one works.
Also, the error messages of the text delivery reports sent to my phone while my O2 sim was in it say "Interworking Not Available" (this is from an Orange phone). Any idea what that means?
Thanks to anyone who can help.

Shot in the dark here: how did you get your Hermes? Could it be blacklisted from O2 - i.e. could it be stolen from an O2 subscriber. (I would assume by the person you got it from, I am not accusng you of anything!)
Hi Todd,
Thanks for your reply. It's not something I'd thought of but it could fit the scenario. I got the phone off eBay back in January and had no problems with it until now. It's actually a T-Mobile branded one, (i.e. the MDA) rather than the XDA Trion. When I phoned O2 to ask if my account had been blocked and to get a new sim the person I spoke to said there was nothing to indicate that my account would have been blocked, which would presumably include any blocked IMEIs that were listed there. Also, if the phone had been blocked after being listed stolen it would have been blocked on all networks wouldn't it? If my new sim doesn't work I will phone O2 and ask them if my IMEI is blocked, so thanks for your suggestion.
As updated in the first message, my IMEI has been blocked, causing all the problems. The reason the Orange sims worked must be because the block hasn't propagated to the Orange network yet.
Hey i discovered i had the same problem today aswell i bourght the phone of Ebay for the first day it was working then next day i upgraded to WM6 and it stop working i did some research on why it stop working and here it was
Orange & O2:
If you place an active orange or
O2 sim into a blacklisted handset you
phone will not show any signal strength
at all! If the handset is a Nokia then a
"SIM card registration failed" message
will also be displayed. If your handset is an
Ericsson then an "Invalid Mobile" message
will be displayed. For most other manufacturers
the handset will simply show no signal!
Vodafone & T-Mobile
If you place an active Vodafone or T-Mobile sim into a blacklisted handset, the phone will appear to function perfectly UNTIL you try to make an outgoing call. When you try to call out from the handset you will hear a sequence of beeps and then the call will be dropped!!
wow nice story man , it seemed like a movie or something
anyway before i finish it i expected that your problem is that the phone IMEI is blacklisted . since its working with orange and other sims . its usually normal to get signal but u wont be able to make or recieve phone calls .
good luck .

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.

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.
Bill
can you share a link with HTC Field Test?Thnx

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.

[Q] perhaps a new TG01 user

Hi,
Since my HTC universal broke the LCD I start to find a replacement.
I found a friend who have a TG01 with no use... and he borrowed the device before I buy it.
I am running with the device since last Sunday, and I must say that the cons of this device (battery), for me it´s ok (4h30) of use (mix of calls, emails, etc).
I can not reach this time with my HTC
I had found some "problems" but already solved, using search in here.
But, on other side, I have some problems that I could not found the solution.
1. I can not put the device in 3G, only in 2G (I try changing in appropriate settings zones).
If I put in "automatic".... always in 2G and my home area have 3G.
So I decided to leave the device with GSM only.
2. Some cases, when I make/receive a phone call, the others persons inform me that
they can not hear me correctly (like I have poor signal, but the times I could check the
signal, it was full).
3. I use the TG01, with a bluetooh car kit (he did not access the contacts in the phone)
Works fine, but yesterday I found that the TG01 was "frozen" several times in the
day...???
In the evening I found that the freeze are related with bluetooh connections to the car
kit. Connecting/disconnecting.
The 3 problems that I have should be related to radio version???
I have:
software 5005.0000.0171 SP-00
radio version 5005.0000.0171
Thanks

Hi,
Yes your problems are from the radio version and from your carrier nerwork!
I have the same problem in Romania because i have more phones and also 3 carriers.
In one case, I use this phone with the Cosmote carrier from Romania it gave me the same problem as you have (the Cosmote carrier has two networks- one for GSM (2G) and one for 3G). Because the two internal network my phone see that i am in roming and give all that problems!
I installed the Feropont rom ( http://forum.xda-developers.com/showthread.php?t=969087 )and it works ok by now, Mirolg roms (http://forum.xda-developers.com/showthread.php?t=906969)was also ok for me untill a point (is with Sense)!
Another rom I tried is fxdjacentfxd (http://forum.xda-developers.com/showthread.php?t=993343) (best free memory) unfortunatly it gave me an error because of the carrier and i changed.

Thanks very much!!!
for the links.....
I installed feropont rom !!!
Looks fine, but still have the problem of 3G...
Tomorow I will check the sound!!!
Thanks again!!
Perhaps I quit!!!
Hi,
Well, I try radio 1600 and now 300.
In this weekend, 1600 still have bad quality sound (people can not hear me very well).
In this morning (early) I flash again the same rom with radio changed for 300, but still haven´t 3G (for my experience I think I will have sound problem).
Today before flashing I put another SIM card (vodafone) and ... I have 3G, after changing the settings.
I leave the settings in HSPAD, put my TMN sim card ..... and no signal!!! (like usual).
My SIM card what is giving me "problems" had +- 4 months.
(Had 3G in the HTC Universal, with same card).
So, my problems could be in the SIM card (I think not)? what did you say?
After flash and reflash and because I use TG01 for professional use....
Pherhaps I quit!!
Thanks to everyone!!!

I told you!
The problem consist in the equipment carrier use! Vodafone use Ericsson devices and Orange use Alcatel stuff, but other carrier could use other equipment and from here comes the errors.
I don't think that the error comes from your SIM card !
I think the error come from the radio in your phone witch is not adequate with the carrier equipment. So my advice is keep looking for another radio! Try 1700!

Your Right Rila, the problem could also be in the TG01.
But my SIM card, in my wife phone or in another phone with 3G could not "enter" in 3G.
(I did not use 3G in my HTC universal, the sound also wasn´t good, but I always think it was for my blue tooth car kit or bad signal reception)
The same with my old Qtek S200(who don´t have 3G only GSM)
The sim had 4 months old.
For future "helps" I try 1600;300 and now 321.
I am waiting news from the operator.
First I must have a SIM that in other phones, work in 3G, after that, let´s test in TG01
I will post the news
(I must admitted I star to get TG01 addicted )
Perhaps I do not quit!!!
Ok!
In my break launch, I go to a store from my carrier!
They did found one problem, in my "service"!
After 30 minutes they call me and ask to reset the device ( they know it was a Windows mobile phone).
After reset, I select hspda settings and I have now 3G.
I put again the Tg on GSM only ( for saving battery).
In +- 10 calls no one has inform me they can not hear me well.
It´s soon too say that the problem it´s SOLVED but it´s looking good
Another think that I noted is that I have 1H55 m with 70% remaining battery.

Talk Mobile UK issues

I have had my TITAN since about a week after its release. At that time, I was using an O2 SIM card and everything was perfect and fine.
Around 4 weeks ago, I switched to Talk Mobile as my O2 contract was up and I got a deal from Talk Mobile. Since then, my phone has been a disaster - but I dont think the TITAN is at fault.
Around 50% of all my calls get dropped. Typically, when this happens, I will be connected to a 3G/HSDPA network with decent signal strength. The call will drop, I look at the phone and the signal has been lost entirely. Then the signal comes back but at GPRS or EDGE. I also often have a GPRS or EDGE connection in areas I know have strong 3G signal. The phone will transition to 3G eventually but it is a right pain.
I am already on my 2nd Talk Mobile SIM card and will try a 3rd this week. I have tried hard resetting my phone too. None of this has helped and the network have so far been typically useless in trying to help so I was wondering if any of the bright people on here would be able to help at all.
Many thanks
Sounds like a network issue, I am on Vodafone and have not had any problems with the handset. Make sure you have correct network settings installed on the Phone like APN's etc for Talk Mobile
Are they listed in htc connection setup? if so run it.
Talk mobile piggybacks vodafone iirc. i get this problem of switching 3g/edge/gprs with vodafone and talkmobile. with talkmobile if its a phone they don't sell they don't seem to have the settings for internet/mms etc. i usually have to manually input them.
If you need to manually input the Talkmobile settings, they're all on the website.
Click the second orange button 'Talkmobile phone settings' and they should be listed in there.
talkmobile.co.uk/get_your_settings.html
Thanks to all for the responses. When I run HTC Connection Setup app, there is a setting for Talk Mobile which I selected. Before doing that, I had no internet as obviously Windows Phone on its own doesnt have the right settings.
I will try manually entering the APN details next and see if that helps, but I dont think the APN affects voice calls if I am right?

I am complaining vigorously
You've checked the aerial right? http://forum.xda-developers.com/showpost.php?p=18523952&postcount=12
I have a Talk Mobile sim (I got it as it was an offer - unlimited data) and a Vodafone sim. I have the same problems with Talk Mobile.
E.g. today I could only get Edge in London, and it seemed to be slower than basic G. When I swapped to Vodafone sim, in same area, suddenly good H signal, and fairly fast.
Also my pop3 email sometimes just errors with the Talk Mobile sim.
When I first got this TM sim in November it was great, downloaded no end of music and data on the Titan. Past few weeks it has been rubbish. I find calls are ok though.
Haven't got as far as complaining.... yet.... sorry have no answer but just to say that I don't think it's the Titan at fault.

Elephone S8 Weird issue with network

Hey all,
I am hoping somebody can guide me in regards to an issue I am facing.
I was working on my car a few days back and left the Elephone S8 on the car seat not realizing that it was being hit directly by the sun. After I was done, I picked up the phone and it was very very hot. I then went inside and let the phone cool off.
Since the above, I notice that I struggle to pick up reception. I have tried different firmware, replaced sim cards, everything. It seems to only be affecting certain MHZ bands as 4G LTE work, 3G works fine, and 2G works find but not always.
I have a feeling the 2G is having issues but maybe only certain bands. I do not think it is software related but have no idea where to even start on the hardware side. I first want to try scan for towers and see which bands they use and try see which one could be giving the issue. I don't expect it to just be a lose connector as the phone has not been dropped and I have only been using it for 2 weeks. If I do send it back under warranty for repairs, they will never pick up this issue.
Elephone S8 loss of network issue
Hi.
I think is a hardware issue as the same thing happened to me after 3 weeks perfect use.
I think has nothing to do with the sun as for me happened on a snowy Sunday 10th of December in London.
I suddenly noticed that when sending email the sending would start fast and after a 2-3 seconds the network will drop to 3G and stay like that for long time until the mail app stops sending process and the phone goes back to LTE 4G.
Also when dialling a number the phone will drop from 4G to 3G and than loose the connection straight away.
When indoors the phone would have trouble registering to network for ages without success.
I picked up 4 different pay as you go cards to make shure that is not my network but still no success.
All documented in the support ticket to GB and yesterday have send it back for a refund.
I really like the phone but i am reluctant to buy another if the issue persist so will wait and see.
Hope some more comments will follow to highlight the problem and influence a solution to this.
Cheers
I have the same issue - my wireless connection inside my home keeps dropping and connecting off and on again and again - I have two routers and maybe as I move from room to room it tries to connect to the closest router or something like that - not sure if there is a way to fix it without doing something in the routers.
Wifi

Same problem here
My network problems are a little different. I don't have problems connecting to different wifi networks (home and work) but the phone does not activate mobile data when leaving a wifi network. I always have to restart the phone when I want to use mobile data (3G).
Kind of the same problem. Have my S8 for about a month. First it has a wifi network. When I leave the place where it is connected to wifi, it goes to 4G. But when I come back to a place with WIFI, the phone does not find any WIFI network. I have to reboot the phone. Soft reboot(a little faster) will also do/work.
Are you guys on the stock ROM?
Were you guys able to resolve your issues

I have the same problems with stock rom and eragon rom. I don't have a solution but I'm still hoping for a new update.
For now I found out that turning flight mode on and off again helps to switch between wifi and mobile data, so it is not necessary to reboot the phone every time.
I can confirm as well that Eragon won't resolve 3G / 4G network issues.
I'm using my S8 for a week now with only one problem, call related.
No wifi problems but after one day of usage I couldn't use mobile data anymore I almost re-flashed my phone (unlocked bootloader, rooted and using Xposed). Turned out my provider f*cked things up. Probably because Elephone is a not known brand here. It took me some time to convince the agent on the phone that I do not own a Samsung S8 lol.
Problem was solved at the providers end.

This information sounds interesting. How did you manage to 'convince' the providers agent that it is not Samsung? And what did you tell it instead?
Steve the issue you have is different. Your issue won't be resolved that way.
You would need an app that switches to 3G/4G if WiFi is not connected.
Happy too soon. After one day with mobile data it's gone again. There's a cross in the lower right corner of the mobile data icon in the status bar. I'll be calling my provider again tomorrow morning.

I'm not sure if the fact that I own a brand that is unknown here causes the mobile data problems. The problems I'm running into atm are
- mobile data problems, 4G is connected, but no internet
- fingerprint scanner doesn't work with my banking app
- backlight bleed in the middle of my screen
- after 3 out of 4 calls, phone freezes for about 30 seconds
- rattle in fingerprint scanner
I guess I'm about to find out how good the return policy at Banggood is ?
I highly recommend that you return the phone now.
There are so many issues with the phone that it's just not worth the time.
Hi guys, I just got the phone, but mobile data is not working. Am I missing something?
Can you attach a screenshot

Does your sim card work in another phone? If so, are the apn settings the same?
I managed to resolve the issue.
I'm trying to figure what went wrong at start. When I got a phone I inserted both SIM cards like this:
SIM 1 - my business phone number - provider 1
SIM 2 - my personal phone number - provider 2
I wanted to use data only on my personal phone number, so I disabled data on business number. What happened is my business SIM downloaded APN info on first boot (i assume), and then my personal SIM used this APN (which was incorrect).
To resolve issue I first inserted my personal SIM to slot 1 alone and booted. Then I changed APN profile to match my old phone's, turned off phone and inserted my business SIM to slot 2 and booted.
Now data works fine. Obviously there was APN issue but how come that phone didn't get correct APN settings per SIM?
Thanks for support!
