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

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.

Help needed using Orange Sim in XDA Mini S

I have two XDA Mini S phones, which I believe are fully unlocked. I am able to use a Vodaphone sim in them and everything works perfect. When I put my works Orange sim in them the phone works i.e. I can make and receive calls but the Sim Manager does not work. Which means I cannot access the contacts on the sim card or use the options menu to configure the phone. When I try to access the options menu I get the message " the phone is not ready, please wait 15 seconds and try again"
Has anyone else had this problem and gotten over or around it. I have spoken to both o2 and Orange and they are both an absolute waste of time. I would appreciate all the help I can get. Thanks.

Hi,
I am on orange too, also had the same trouble. I could make and receive calls, but could not access sim card to add contacts or send / receive texts. The XDA mini is a 2G phone, my orange sim is was a 3G. When I changed it for my wifes 2G orange sim, all worked perfectly, so we just swapped sims and phone numbers. Tried to get a 2G sim out of orange on my contratc, they were having none of it, said I would have to go PAYG. So I did the swap with the wife and extended the contract.
Hope that helps.

Thanks for your advice Mlkey.
Following your response I contacted Orange and changed my works contract 3G sim for a 2G sim on contract. This still does not work and as usual I am getting no real help from Orange.
Looks like the only solution will be to change my mobile / pda, that is, unless anyone else has any other possible fix.
Are PAYG sim's different than contract sim's ??, if they are does anyone know if I were to get a PAYG sim that worked in my XDA would I be able to get my company number transfered to that sim and convert the sim from PAYG on to my works contract account ???.
I would appreciate all the help / advice I can get, before this drives me mad !!!

XDa wizard and Orange sim only
Hi,
I'm having exactly the same problem! O2 to Orange sim only and completely no SMS. Orange support is argueably the worst. Interseting to here that it's version. ie G4/G4..Have read somwhere that VOip SMS maybe the solution? ...If i can find the thread again I'll post a link.
Cheers

Fixed this problem by using the t-mobile 2.26 rom as described in "Definitive Guide to unblocking and rom upgrading g3 wizards

I am having exactly the same problem. My phone is a G4 and I believe it to be fully unlocked from o2. According to orange my sim is a G2 sim because the 7th number of the sim card begins with a 2 and not a 3. I cant even try a different rom because I can't connect to my computer with active sync through usb or bluetooth this has been for about a year now.I usually transfer files through a card reader. Can anybody help me because the deal with orange is really good but the phone is useless without sms or mms and I really dont want to change the phone.

Hi,
I am new to this forum. I have exactly the same problem . Has anyone found any solution to this/ Please help!

The solution is to upgrade the radio rom

Unlocking Hero from T-Mobile to O2?

Bought a 2nd hand hero (tmobile). Unlocked it with http://www.unlock-now.com and put my O2 sim card in... and nothing. Have tried with my prepay O2 card, PAYG O2, 3 and T-mobile cards and only the T-mobile one works.
Flashed it with various different ROMs but each time I get no service; when I go to \mobile network settings\network settings\search networks I can see O2-UK but when I select it I get "your SIM card does not allow a connection to this network" (although it works in my Touch 3G).
BUGGER! have looked everywhere, but for the life of me I can't find a fix for this.
Would really appreciate any suggestions; my Touch 3g is very flaky and I need a reliable phone asap- live deep in the country and wife about to have a baby!

don't know what else to, BUT, when you get it working i've got all the settings from o2 for the mobile web and mms. i would post them now, but haven't got them to hand, will do soon
good luck

NOOB - T-Mobile UK HD2 unlocked - no O2 connection..

Hi guys.
Really sorry about this but I am at the end of my tether with this!
I run my own IT support company and one of the things I do most is Blackberry and iPhone Exchange email syncing. While both of those work brilliantly, I have had users having loads of issues getting their Windows Mobile devices working easily. Luckliy only one or 2 have these devices but more are asking....
I resorted to retiring my Bold 9000 and got a brand new sealed HD2 on the UK T-Mobile network today. First thing I did was get a sim unlock code and that went through first time (using my working o2 SIM from my BB). However, I couldn't make calls so after I spoke to o2 I got in to the Phone, Network settings and with the Network selection on auto, the preferred networks list was blank. Clicking the preferred networks button brings up the list of preferred networks, ticked o2 - UK and ok'd it. Goes back to main network screen and still blank. Clicking Find Network then brings up cannot register on selected network.
Changing automatic network selection to manual, selecting )2 - UK and ok'ing that brings up the same 'cannot register on selected network error. So, after coming here, I stuck on the HSPL 1.42, then upgraded to RUU_Leo_HTC_WWE_1.48.405.2_Radio_Signed_15.28.50.07U_2.05.51.05_2_Ship
That went on fine and after wiping to factory to make sure I sent through the set up. Same errors and still can't make receive calls.
Stuck on the 2.08 hspl for the hell of it then upgraded to RUU_Leo_HTC_WWE_1.66.405.2_Radio_Signed_15.30.50.07U_2.06.51.07_Ship
Guess what? Exact same problems! I spoke to o2 support and they were pretty useless. Explained that it was sim unlocked and on a generic firmware. They said that T-Mobile do something weird with the HTC and I should try calling HTC tech support, who are now closed...... I am not sure HTC will be of any help anyway as I can't exactly go telling them I have stuck on the HSPL and a non-approved firmware for what was the originall carrier!
Help please anybody?? I have googled and googled but haven't found anyone with the same problem, I might be being blind. BTW, what I guess is the antenna icon has an exclamation next to it
Thanks,
Nick

Quick update. Housemate got back so I nicked the Vodafone UK sim from his iPhone and stuck that in the HD2. Same problem, won't register on Vodafone either. Anyone?

Got annoyed. changed the SPL back to the standard 1.42. Installed the latest T-Mobile official firmware. Same problems. Do I have the only HD2 ever to be doing this? . I don't have a T-Mobile sim to hand and the nearest store is miles away sadly.

Does your phone app not work at all ?
How do you know unlock code worked ? so far every sim you tried has failed.
Where did you get the unlocking code from ?
How did you use it ? meaning how did you input it ?
Verdict so far, if a t-mobile sim card works then unlock was a fail !

Ok referring to your network selection, for the UK, you should have it set to Automatic, it will then use the network associated with your sim.
referring to your call problem, does the phone still work with the original t-mobile sim?
if so it sounds like your unlock code didnt work.
if your phone no longer works with the original t-mobile, I should think something has gone wrong with the radio software you have installed on the phone. Try going back to the stock htc/radio rom. If that doesnt work then the phone probably needs to go back to t-mobile for repair, at this point you tell them "it just stopped working"

have you tried to run the connection setup wizard?
settings - menu - all settings - connections - connection setup
if there isn't one, connectionsetup is available as a cab.

Hi guys. It was a brand neww, sealed box HD2, but from T-Mobile. No SIM with it at all or I would have been trying that too of course .
Regarding how I unlocked it. I paid an ebay seller to give me an unlock code. When I fist put on 02 SIM in the phone it wafffled on about being network locked basically and had a field to enter the unlock code. Entered the code given to me via the Ebay unlocker and never got that message again on the screen. Is that wrong somehow?
Manual network, auto network, selecting carrier etc all of them make no difference. I am off out now but have found a local store with PAYG T-Mobile sims in stock so will grab 1 later today and see what happens then.
Will update/bore you all later!
Cheers,
Nick

Right, case closed. I got the T-Mobile sim and stuck it in. Showed up with T-Mobile on the scren and a good strength signal. Tried to make a call, dropped back to the home screen almost straight away. I had full data access though. Spoke to T-Mobile who informed me that my brand new, sealed box HD2 was blacklisted and I could do nothing with it!
Vodafone and O2 just flat out don't let you register the handset on their network if is it blacklisted it would seem.
Contacted the seller and he has arranged a refund, but the refund is showing as 'pending' so I am not going to return the phone until I see it physically in my account.
I have to be honest and say that this is actually a good thing as despite HTC doing all they can to make the Win 6.5 on there look less dog-like, the overall UI is still pretty awful. Now,this phone with Android 2.1 on it might be a dfferent matter! Back on my Bold 9000 for now......
Cheers,
Nick.

I am sorry to hear about that, looks like to you got hit by some sort of scam, probably resealed a second hand or refurbished unit into an original box and sold it as new.
regarding the UI of the htc devices, I am not really sure why you think this, htc hd2 uses htc sense which is the same ui as on the android htc phones. The only windows mobile thing you should really see is the start menu which has been praised as being a very good replacement for the old start menu. even all the settings windows are run through the htc sense ui so i am really not sure what you are complaining about :S
If you dislike the top bar/bottom soft buttons, there have been a lot of modifications to these in more recent hd2 roms, maybe you should to take a look at the roms section to see some pics.

Weird Problem with 3G and H connection on UK O2

Hi,
I have been in touch with HTC and O2 about this. HTC are prepared to take the phone in for service but wonder if anyone here can suggest anything.
My SIM-Free from new HD2 will not connect to the 3G or H network. It works fine on G but the data download is very slow (as you'd expect). It worked fine on 3G or H up until a few weeks ago, not sure when it stopped exactly as only notice the slowness if I'm trying to send a large email attach such as a pic.
I have flashed with the latest stock ROM on UK HTCs website and the problem remains.
O2 have confirmed there are no blocks or other issues with my account and have sent me a replacement SIM but the problem remains.
If I take the O2 SIM and place it into my old Kaiser it connects immediately with a nice H up at the top and a visit to speedtest confirms the fast connection.
If I take a colleagues Orange SIM and place it in my HD2 after the usual SIM card swap wizard does it stuff the HD2 will once again happily connect to 3G/H.
I wondered if somehow my HD2 had had it's IMEI blocked for 3G (or something) at O2 but the helpful tech insists this is not the case.
I am at a loss to explain this as anything other than a phone fault and I suppose I will have to send back to HTC but didn't want to be without it for the 7 working days it will take.
Weird eh!?
