Hi,
I have an AT&T Tilt and I am trying to make it work here in Brazil, with Claro provider.
I did the SIM unlock, SUPERCID and Unlocked security, BUT I still can't get any service. I also tried several ROMs and RADIO combinations.:confused:
My phone keeps searching for network and don't find anything.
I already set the band mode to GSM (which is the band type here where I live) and still can't get it working.
Anyone have an idea about what can be wrong?
Thanks in advance!

You try the network configuration wizard? You can poll the device to make sure the SIM is indeed unlocked too. Also, make sure the radio you select is compatible with your rom choice.

It could be the frequency band selected for the GSM network. I don't think it's a SIM problem, since that usually comes up with an 'Incorrect SIM card' message, when it's not unlocked.

There are two bands for GMS, and I'm not exactly sure how you would select which one to use, since I don't see the option under Phone (green button)/Menu/Options. Another phone I had had a selection screen available where you could specifically select which band to use.

Hi,
my ROM is 1.82.721.1 WWE and RADIO is 1.27.14.09. I think there isn't any incompability on both.
I already tried to select the GSM bands manually. No success.
I also disabled HSDPA to prevent any issue.

I forgot to mention that the network wizard does not have an option for chosing Brazil as country.
Additionally, every time I turn the phone on appears the following message:
YOUR CURRENT OPERATOR (72402) IS NOT SUPPORTED. YOU SHOULD OBTAIN AN UPDATE FROM YOUR DEVICE VENDOR.
Another info: I am using Windows Mobile 6.0.

Looking here (http://www.gsmworld.com/roaming/gsminfo/cou_br.shtml), I see that the carriers using Claro Name use GSM1800 (and 3G850) which are supported by the tilt.

I wonder if the problem is that the IMEI number needs to be registered with the carrier? I know some european countries (like turkey) require foriegn IMEI numbers to be registered before they will work.

Hi,
my ROM is 1.82.721.1 WWE and RADIO is 1.27.14.09.

Good catch, not only is that "an" at&t Radio but it is quite specifically "the" at&t Radio that only works with the at&t 1.6x.xxx Roms.

Although the OP did state they have used other Radios & Rom.

So, which combination would fit?
I don't need any at&t program, so the ROM would be e HTC.

Well, firstly, you must be getting a signal in order to get the operator MCC-MNC, so that part's out of the way.

Secondly, the error seems to originate with the "Network Wizard" program which handles auto-setup. Personally, I don't cook this program into my ROM's as I prefer to cook the settings right in and avoid the added bulk of that program.

Thirdly, a google search brings this up: http://209.85.173.104/search?q=cache:p9FxXFCMXLgJ:www.expansys-usa.com/ft.aspx%3Fk%3D103269+YOUR+CURRENT+OPERATOR+IS+NOT+ SUPPORTED&hl=en&ct=clnk&cd=2&gl=us&client=firefox-a

Lastly, it almost seems as if the Network Wizard is stopping you from using the network due to not having configuration settings for it? That's pretty whacked out.

I flashed the following: HTC 1.56.405.5 ROM and 1.27.12.11 RADIO (they come in a pack, so must be compatible).
There isn't the Network Wizard anymore.
Now I have Connection Setup and the message does not come when I turn on the phone, but the problem remains, no network.
There is 2 questions I wanted to make and can be the source of the problem:
1- Can I flash HTC roms in a AT&T Tilt?
2- Does make any difference choosing a country and operator at Network Wizard or Connection Setup? The phone does not work if I ignore it?

Not to be funny, but go to the CommManager and see if the Phone is turned on

I flashed several ROMz and the default in the CommManager was Phone off...it had me going for about 15 minutes the 1st time and 10 minutes the 2nd time.

If your Rom-Radio combination is correct...again, make sure the phone is on in the CommManager.

Checked this several times. It is not that.
It's possible that my phone will only work with a brazilian operator ROM??

Hi..
I'm from Brazil and my Kaiser has no problems connecting to my network (TIM).
Afaik it shouldn't have any problems with Claro; take a look: http://www.pdabr.com/viewtopic.php?p=22232&sid=e678102e6b1f73d179dace0ec6c57793
As you see, their tytnII works fine with claro (they are trying to configure gprs)

I'm not sure if the IMEI registration for foreign sims is correct... I've taken my Kaiser (also Hermes) to Brazil and Turkey and they worked fine. I did have problems in Brazil with auto network selection but my phones worked fine with TIM and Claro when manually selected.

On a note with the IMEI - did you buy the phone new or used (ebay, small dark shop, man on a street corner etc). If it is used then there is a possibility that it's stolen and the IMEI is barred - you can check this by calling your service provider.

Welcome to the problem , GOINGTOBRAZIL! :)

Now it seems that there are more atleast 3 ppl here in the forum with AT&T TILT having this no signal problems! first i got it, then goingtobrazil, and then Williegonza!

Following are threads made by me and williegonza:

Unfortunately i am stuck with this problem from past one month, I have tried a lot of different methods, but have failed. So long, i am also looking for the solution for this problem...

This morning a friend of mine told me that around 10% of AT&T Tilt phones are having this problem coming up! :(

Welcome to the problem , GOINGTOBRAZIL! :)

Unfortunately i am stuck with this problem from past one month, and have posted 2 threads on this problem here in the forum, and no replies to one of them, and for the other thread, was asked to reflash original htc rom.

I have tried a lot of different methods, but have failed.

So long, i am also looking for the solution for this problem...

Please help us guys!

thanks a lot!

Do you guys both have the TILT or HTC version of the Kaiser? Mine is HTC branded and worked fine in Brazil.

Did you buy your phones new and in Brazil? If so then you should just get your supplier to replace them. If they are used then there is a chance that they are stolen and the IMEI is barred. If you got them overseas there may be some carrier lock installed (I seem to remember something like this with the X01HT versions of the Hermes).

Sorry I can't help out on this but maybe by bumping this thread someone else can help.

It may help if you give some more info about your phones such as:

ROM version
Radio version
HardSPL yes/no
Information from bootloader screen
Does your device info IMEI number match the one on the sticker?

This might help the technical gurus spot a solution.

Hello ACH2,

Yes, we 3 are having the TILT phones from AT&T.

For me, it was working fine for a month, and suddenly one fine morning it stopped working.

Before that i had flashed couple of dutty's roms and no problems at all... it all happened suddenly!

About the rom and radio versions, i think that wouldn't make a difference, as i have gone thru all the roms and radios here and nothing helps.

I have tried the WM6.1 roms with respective radios, and also the WM6.0 roms with their respective radios.

This is totally a strange problem that has started erupting in the AT&T Tilts all of a sudden! :(

I request the mods to make this sticky, so that more people can report their problems here in this single thread, unlike the 3 threads floating now for the same problem.

Thanks.

Hi,

I had the same problem and tried everything.. So I contacted HTC and mailed in and they fix it for free.. They said the main board wasn't working propraly so they replace it for free. KNow I have my phone and it works good. Just go to HTC.com and contact them and make sure you tell them that you bough it from an att store.

I contacted HTC Brasil, could get an Service Order and sent the phone to them yesterday. They didn't guarantee a fix cause the phone sold here it is the TYTN II, not the Tilt, but I hope they fix it.
I am now almost sure that is not a software related issue, but a hardware issue. I recommend all the guy who have this problem to contact HTC.
I will post again when I have news about my phone.
