Problem connecting to O2 after unlocking XDA

Hello all
My colleague posted this message a couple of weeks ago, but didn't provide full info and as such the replies did not work. :roll:
So here it is. I would be grateful for any advice.
I unlocked my xda I, using a software I downloded from here, which was previously working on O2 UK. After that, it doesn't work with any O2 Sim. It works with all other UK sims (Vodafone, T-Mobile, Orange). But not O2. The O2 sims are ok as they work on other handsets and specifically my unlocked XDA II and other handsets ( I have tried 2 different O2 sims).
But no joy. I even tried to change the GSM frequency on the XDA through boot loader (even though I didn't have to), but no joy. I have gone through the auto config several times. but no joy. I even re-installed the latest O2 firmware and radio update (from the O2 web site), but still no joy.
I am running out of ideas. Does anyone have any idea? Should I try and downgrade the firmware and radio stack and try again? Can I do it from the original CD?
I would be grateful for any ideas.
Cheers
Nima

Can you tell us the nature of the error with an O2 sim, what is shown at the signal level meter, what happens when you attempt a call etc. Please leave the radio stack alone, your phone is working on 900 and 1800 bands so that is not the problem. Was the sim that you have at the moment working on this phone on O2 before the upgrade.?

Hello Thank you for your reply.
When you turn the phone on, it asks you for the SIM pin and the device works fine in every other way. But you get no signal. If you try to make a phone call, you get the phone dialer screen and you can dial the number but, obviously, it disconnects more or less immediately. If (from the phone dialer screen) you try and go to options it freezes and doesn't show you the options screen and then you can only exit the phone dialer. Also, I put the GSM frequenct back to what it was. I haven't changed anything in the bootloader mode anyway. I had problems with the original O2 sim after the upgrade (funny enough, it worked for a day or two), but now i don't have that sim as the contract finished. By the way, both of the O2 sims I am trying now are contracts and NOT pre-paid.
Well here it is. I hope this helps to let you figure something out. I would be grateful for any ideas. What about formware downgrade? what do you think? could it help ? is it even possible?
Thanks a lot.

It presents as a blocked phone, if you look closely at the signal meter after a soft reset you may see the signal come up but then drop back to nothing. It may be coincidence that it stopped working with O2 2 days after the upgrade. I have seen this happen with phones that either have been subject to insurance claim or where a contract was not fully paid up for the 12 months, however it usually means it will be blocked on all networks. It does not look like a rom downgrade will work, also as said before, if it works on Vodafone it should logically work with all other 900 mhz bands.

"Unknown SIM Error" on MDA Pro on T-Mobile

Hi,
I just bought an MDA Pro direct from T-Mobile's website and it was delivered today. Unfortunately, while the PDA side of things works perfectly, it won't connect to T-Mobile at all.
On the 'T-Mobile' start up screen it displays the text 'No GSM' above what I think must be version information.
It reports 'no service' in the phone status bubble, and SIM Manager says: "Only emergency service calls can be made without a PIN" When I enter the PIN I was given, nothing happens. I think it goes into 'change PIN mode' because then I can put two more 4-digit numbers in (it doesn't matter which!) and then it says "Unknown PIN Status. Unknown PIN Error"
Unfortunately it isn't just a SIM problem as the SIM works in my O2 P800.
I've spoken with T-Mobile and they want to swap the handset, which would be fine if they had any in stock! I'm wondering if anyone here had any advice on ways I could try fixing this short of waiting for them to get in touch and tell me they have another handset I can try.
Any suggestions would be much appreciated!

Hi,
what is your local provider ? Is it T-Mobile, Vodafone, E-plus or O2 ?
The mda pro only works with a t-mobile sim !

Try to clean the sim before putting it back in the MDA Pro,
Generally works for me!

i had the same problem with my jasjar here is Australia......my sim works on any other pda and phones but not the jasjar.....apparently the sim that i have or some of the new sims have a little higher voltage than normal.......and the jasjar dont like it.....so what i did was replace the sim with another one and that worked......al they had to do was port my number to the new sim......but before it did that tried to put the sim in first and it started to look for a network so i knew this was gonna work......becoz before when i put my old sim in it just says invalid sim or no sim........so try replacing ur sim with another one......perhaps try and get an old sim maybe the sim has some in stock.....i bet ya that will wrok....good luck

Thanks guys ... I'm trying to find an older T-Mobile SIM to try. It's just frustrating! I've tried giving the SIM a wipe, to no avail. If it is that the SIM is slightly incompatible, T-Mobile sending out another unit won't really help, right?
How annoying!
If anyone else has any great ideas I'd love to hear them!

try using someone elses sim and put it in the device and give it a try to check if its definitely the unit and not the sim......when i rang the tech support for optus thats what i was advised.....and they were right....sim voltage was the problem......anyways try getting another sim.

Contact customer services.
The problem sounds like you SIM is too old.
They should ask for your SIM serial number, if its too old they'll offer to send you a new SIM or something else to make it work straight away??? :wink:

The MDA PRO as its a 3G type phone with WCDMA it needs a diffrent sim card that is usaly known as a 3V USIM.
Its the same on Three in the UK, the sims from their phones will only work in 3G phones not standard GSM ones and vica-versa.

Old SIMs (from about 5 years ago) are rated at 5 volts. Newer ones are 3 volts (not just for 3G). Trust me, I work for a certain mobile phone company who sponser West Brom. ;-)
The problem will be fixed in a future software upgrade. But for now you need a new SIM or your phone unlocked.

Trouble is, this *is* a new SIM... I'm moving back to the 'hardware fault' diagnosis I think.
I went to a friendly carphone warehouse shop in Oxford and tried a new (and definately working) T-Mobile PAYG SIM and that gave exactly the same error.
Maybe T-Mobile need to send me a 3G SIM. I guess I'm probably just going to have to wait until they can send me a new handset to see what happens.
Ho hum!

There's no such thing as a 3G SIM. The 3G gigery pokery happens on the phone. There is no need for a different SIM. The MDA Pro has a problem with SIMs with certain serial numbers (Don't know which coz I'm not at work). You need either a SIM that the phone likes or your phone unlocked. Call customer services if you still have your phone.

Had the same problem allready twice in 2 weeks.
One time a soft reset made the device working again - another time I had to take out the sim card and put it in again, then it worked. But all email accounts were gone and had to be installed again.

Hi, thanks for that reply... it seems very useful! If you could post/pm me the numbers of those SIMs that the MDA Pro is unlikely to like I'd really appreciate it... customer services aren't striking me as very helpful (and certainly not knowledgable) and I can tell that if I call them they're still going to say: Wait until we have another handset in stock and we'll see what happens then. Which doesn't help me much as who knows when that will be?
Thanks!

Any SIM serial not starting with 06 or 07 will be affected by the issue.
eg 90043575, the serial starts with 04.
This will be fixed with a software upgrade in the future, in the mean time you either need new SIM or you handset unlocked. For either call customer services.

I got my MDA Pro a few days ago also, had the same problem as you, basically the handset is network locked, not sure how they managed to lock all UK network, basically give Tmob a call and make sure your stay on the line until they provide with an unlock code, i got mine, now my old sim works and my handset is unlocked

i had the same problem with my ASUS P535 (here is France) with new SIM card.
seen from :http://vip.asus.com/forum/view.aspx?id=20070818011855796&board_id=6&model=P535&page=1&SLanguage=en-us
Thanks.

I had the same problem BUT-
I had the same problem but i had been using the sim card successfully with the exec for a year, after a hard reset it doesnt recognise the sim. will a ROM upgrade fix it or is it a hardware failiure?

My solution

I had this happening to me just last week with a card that works all the time. Then followed that I had no sound coming off speakers or bluetooth. In my case it was a third party software problem. Don't ask me which as I install and uninstall too many applications and my Uni gets in a tangle sometimes. A soft reset instantly (in terms!) restored phone activities and sound, so I recommend a reset if you haven't tried it already. Maybe you will need more than one.

NO SERVICE? - For no reason

Hello..
I last night put my phone onto "flight mode" so that i was not distrubed in the night if a text came through....
this morning i set it back to normal but the network reception reported NO SERVICE
when it had not come back this evening.... i put my sim in a different phone and used a different network's sim card in my pda.... NO SERVICE was reported for this as well but the sim that was placed in the other phone registered on o2 as soon as the phone was switched on
I've only just bought my MDA but off ebay... although it was new i am unable to contact the seller... please can anybody help??
email me to [email protected] or [email protected] if anybody can help
Thanks

MORE info re above
Hi again
In my frustration I have swapped sims again and this time put VODAFONE pay as you go sim in the MDA Magician above.... It found the network and i was able to ring/text from it.....
On putting the O2 Sim Back into the MDA it said NO SERVICE again.....
But using that very same sim in my nokia finds a network.....
The MDA is originally a TMOBILE one that has been unlocked...
ANY help on this would be very appreciated as I'm very annoyed that it's stopped working.
Thank you

Soft reset?
Although, I think taking your batter out and swapping sims may count as a soft reset.

Thanks for the reply - but again that did not solve it... besides to eliminate this i did a HARD RESET as well and re configured it....
I've even RE UNLOCKED it in case this was the problem
(its a T MOBILE PDA) with an O2 SIM IN...... I bought it in November time and unlocked it the same time... My O2 Sim has been working ok in it until the other night when i decided to put it in "flight mode"(so i wasn't disturbed at night)
Im suspecting that it anything to do with IMEI number vs SIM CARD number? Could this have been blocked somehow to that phone?
Its very confusing as it WORKS with VODA sim and DOESNT with O2 yet the SAME O2 sim works in my old nokia 6610.... aaarggghhhh!! LOL

If your MDA works with a Vodafone SIM, it certainly can't be blacklisted for all UK networks since it picks up Vodafone. Secondly, it sounds more like a SIM card issue relating strictly to the MDA. What happens when you try another O2 SIM card in the same MDA?
Make sure the O2 SIM hasn't been damaged in some way, if all fails you might want to take the MDA to T-Mobile to see if they can determine whether its IMEI has been blacklisted for certain networks. Otherwise a ROM upgrade may also help fix the problem.
Good Luck

My guess is that your magician is reported & listed as stolen. Probably not all providers are using the same list with blocked IMEI numbers. Which can explain that one sim works & the other doesn't though works in an other phone.
See if you can find a list for your country on the web. There are some references to such lists in this forum.
Regards, M

check which band your phone is using....
go Phone>Options>band> then select auto

Weirdest Problem Ever..

I have this weird problem with the JJ. I have 2 SIM's with 2 different Operators. The JJ works just fine with one SIM .....
BUT, when I insert the other SIM, I can make calls normally, but I can receive only ONE call (i mean it, ONE), after that the damn thing won't receive calls anymore! (Like the phone is turned off or unreachable)
After trying to make calls for several times it does work, but again, one incoming call and that's it.
I tried that SIM in the 8800, it works just great.
Anybody has an idea on what's going on?
Thank you guys..
PS! I did post this in another topic, but needed some attnetion from you guys, so posted it in a new topic!

It is SIM free btw ..

Come on guys, 80 views and not a single reply.
I need to you that SIM in the JJ.
Could it work by a Radio upgrade or something?

OK, please tell us which version of ROM and radio stack you have.

Sure,
ROM 1.30.69
Radio 1.09.00
Thank you Richard.

the reason there are 80 reviews and no replies is cause nobody knows.
this is an anomoly, way out in left field, that I have never seen ever in all of the forums.
1. get a new sim card
2. get a new sim supplier
3. stop swapping them, and use the one that works
4. take the phone back under warranty and have them fix it.

Tried a colleagues sim card with the same operator and the same happened.. unfortunately there are no other sim suppliers.
the reason i want to use this sim in the jasjar is that my corporate email doesn't work with the other operator, there is some routing problem to our email server.
but why this sim doesn't work properly while the other does. its really confusing.

Throw this thought in.....
Could some settings relating to the "phone" usage be stored in the universal's registry that conflict with the other SIM card thats being used. Are both cards UMTS?
Matt

Here is a thought, Is the SIM with corporate e-mail the one that is not working? I have a T-mobile account with Blackberry BES and a Cingular account, two different SIM cards. Both work fine but the TMobile card will not work all the time with the blackberry connect software I have loaded up on my Exec. I called TMobile and they reset my "LOCAL Data" from thier switch and now it works fine.
Your carrier may have to reset some things for you to get your card working again. Just give them a ring and ask them to help you sort it out.

No they aren't ... I tried to hard reset the Universal with that SIM installed, nothing changed, still can't receive calls.
And once the problem happens, GPRS won't connect as well..

Already called them, they can do nothing about it, I traced our mail server using their GPRS, it stops some where is London! :lol:
I will try to down-grade the Jasjar with the old firmware. It might work :?:
Thanks buddies!

Can the Radio only be downgraded? Or I will have to downgrade the ROM as well?

You can downgrade the radio only, Find the radio you want on the ftp and then upgrade or downgrade just that

Here is what I tried so far..
1) Installing Qtek latest ROM, still didn't work.
2) Downgraded to Radio 1.06.00 and the problem is still there!! :evil:
Looks like I will be selling the JASJAR as soon as the P990i is here! :evil: :evil:

I suspect troubling SIM is UMTS (3G) enabled, AND has poor 3G coverage. JJ sees UMTS and spends its time trying to connect, but can't quite pull it off. I'm battling with this and trawling this board indicates that this is the issue; weak UMTS which you only experience witht he one SIM.

Phone doesn't find network

Hello to everyone !
Ok, first of all I want to say that for years I've been reading this forum and it helped me a lot in the past, but now I have a problem I can't resolve by myself.
I have A HTC Magician PM10A that was bought many years ago in Israel from an official dealer. It worked fine back in Israel.
Now I live in Italy and the phone just doesn't find the network. Not manually, (searching and giving me an empty list), not automatically.
I tried everything. I'll write it down.
Putting back the Israeli SIM card.
Unlocking (turned out to be unlocked).
Flashing with Ctulla WM6.1 Rom (WOW!)
Flashing Radio Stacks from 1.0 to 1.13.
Flashing with Some Italian ROM (downloaded from this site).
NOTHING !
Just gives me network error, unable to register on selected network.....
But there is no network ! Just an empty list !
I wanted to install the original ROM that came with the PDA, but I don't have it.
Thank you very much !

I have the same Problem but no solution.

Well, I have sad news my friend. It's the phone module that is dead. I found another XDA II mini with broken screen, changed the antenas - nothing helped. Plus I checked it in Israel again - it's dead. Well, at least I have a really nice pda

f*** this device was awesome all the years.

Indeed it was a great device. But I checked it at my friends lab, he says that it's possible to fix it, but we have to buy some parts on ebay (i didn't really followed), and only than it might work.
It did it's job and did well. R.I.P.
btw, I am a med student, so it uses me great as a pda to all the books and other staff.

i have the same problem.
What kind of part we should change?
i just changed antena and battery with new ones, but no result

Things you should try to fix this:
Hard Resetting
Cleaning your SIM card.
Pushing the little gold connectors on the SIM slot a little bit up with a screwdriver.
Reflashing ROM.
And the last one, which fixed mine problem:
Another sim. When i tried my sim in other phones, they refused to boot, so i just tried another sim, brand new one - it worked! So ive gone to my operator to replace my SIM.

I had the same problem and accidentally fixed it.
Coulnd't get any signal after upgrading it to WinMo 6.1 ROM. I flashed it back to its original WinMo 2003 SE ROM but still couldn't received any signal.
I took SIM card out and put it in different phone (Nokia in my case). Got SIM card error massage on Nokia screen. Took it out again and cleaned it, reinserted back and it worked on Nokia. Then I was curious and tried put the SIM card back in magician. Signal was magically reappear and phone worked back to normal.
Hope this may work for you too.
