T-mobile HD2, unlocked and won't connect to O2

I purchased an HD2 from eBay, it was locked to T-mobile. I immediately purchased an unlock code, installing my old iPhone sim (making O2 aware of what I was doing) and punching in the unlock code. All appeared well, however it won't connect to the telephone network. I'm getting the GSM icon and I can strangley check emails when out and about sometimes. But I can't make nor receive calls.
I've taken the T-mobile ROM off and replaced it via HSPL with ...
RUU_Le2_UK_1.43.206.4_Radio_Signed_15.26.50.07U_2.04.50.22_2_Ship
Which is the standard O2 ROM. It throws up the following error when searching for networks and trying to connect to O2.
"cannot register on selected network, choose another network".
I've tried everything and I'm just about losing it, smashing the phone passed my mind at one point.
I've tried my sim in another O2 HD2 and it worked fine, on all account. His O2 sim didn't work in my phone, which is annoying. So the issue is with the handset.
Before I go insane, I don't suppose someone knows a very easy solution to this issue?

Sii

It's sat next to me on the desk with an exclamation mark on the network icon but the mobile web icon is connected.
Very srtange.

automatic network selection brings back a failure to connect, however manual selection brings back all UK providers, selecting O2. I get "cannot register".
I wonder if it's something to do with O2 barring the handset? Brand new before I opened it. Also it was locked to T-mobile.
There must be a very simple explanation for this I hope.

Sounds like you may have to contact T-mobile for an unlock code.

I've paid this company ....
[unlockdata dot co dot uk for a code and have used it, however that does appear to be the issue from what I can see.
They sent me a code, when placing my O2 sim in the phone asked for it, I entered it and all appeared well. However it must not be the case deep down in the phone somewhere.....

are you sure it hasnt been blocked by t-mobile? Could well be an insurance scam: data usually works on blocked phones whereas GSM doesn't.

Well I've took my O2 sim card out and stuck my T-mobile one back in and the T-mobile one works and the O2 one doesn't, but I can't make calls.
Did some diggging that this ....
I've not been able to use the phone due to it actually being barred from service. Please use the below link ..
www . checkmend . com / uk / verify
With the certificate ID of - CM4510856-D4848
Looks like it's not stolen or lost, but just barred. I wonder why.
Is there any way I can get this removed?

Its blocked then: blocked and barred are the same thing. More than likely the seller has sold the device then immediately reported it lost/stolen to claim a new one and thus not only have a new phone buy also a nice slice of cash in their back pocket.
There is no way that the phone will be barred without having been reported as either lost or stolen and there is also no way of having it unblocked unless you are the original owner, haven't made an insurance claim, and ring T-mobile with the blocking password provided when the loss was first reported to the police.
Personally I recommend you lodge a claim with PayPal immediately as any other line of enquiry will only serve to delay the inevitable: you will not get the phone unblocked.
Best of luck sorting it out.

Complaint logged with Paypal, just have to wait and see what comes of it. Included the link to the file saying it's barred, let's see what the seller has to say about that.
c*ck omlette that he is
Thanks so much for the info and shoulder to cry on, heh heh.
All the best, Sii

Good luck with it mate, hope you get it sorted quickly.

Well I spoke to T-mobile and they said "no idea why we blocked it, it's not listed as stolen or anything, there you go, unbarred".
I can make calls on my T-mobile sim, however it still REFUSES! to connect to O2, even though I've put in the unlock code supplied by the company listed above.
Spoke to O2 customer support and T-mobile, no bars on the phone, no issues are barring by either provider. Just refuses to connect to O2.
Any ideas?
If not, anyone want to buy a £360 2 day old HD2?

I've had 3 sims from O2 already this week, they've been really cool about it.
I've also had to ROMS on, the original t-mobile one, and the latest HTC ROM too.
I can't for the life of me figure out what the problem is, it's very annoying.
I may just put it up for sale on the bay of E, it works perfectly on T-mobile.
I'll try some other flashes this evening and see if that fixes it, however I don't think it will. FUnny thing is that it won't connect to the network but the large [G] connects, which does make me believe it's something radio based.

Been told to check the following ....
Yes in the sim card options type mepd
Network active - locked
Network disabled / inactive - unlocked
ANy ideas how?

Bit of an obivous thing really, but did you have to go through connection setup when you put the O2 SIM in?

Yes, and it won't connect/register/logon/access the O2 network.
This is the confusing thing, it can see the network but won't register with it

im not sure exactly which ROMS you have tried so i dont know whether they would have included a radio update... to be sure flash the radio ONLY!

Can anyone on O2 UK please list the Radio flash they're using and working with?
I did list the ROM I'm currently using in my first post.
I tried this with the originally installed T-mobile ROM (unknown details, apologies) the latest HTC ROMs (United Kingdom 1.48.405.2 and WWE:1.66.405.2) direct from their UK site and then the O2 listed in my first post.
I'll give everything another go tonight, seriously running out of steam on this topic though

Excellent, thanks so much for the information, I'll give that a stab when I get in after work. To save me hunting around, I don't suppose you'd be so awesome as to link to the ROM
Thank for everything guys, I just hope this ROM update fixes something ....

HTC HD2, cannot register on selected network

Hi all, maybe someone has an answer here. Tried other threads, but some are slightly different then mine. I've bought this phone second-handed. Had it unlocked but it wong register on 3mobile network. The phone was a T-mobile, and its sim-card works fine. The 3mobile sim-card work fine in my xperia x10. Thinking about being branded, i debranded the phone, but still no luck. Still giving me the exclamation marc by the antenna with an "X" beside it.
So what i want (need) if no one has an answer for this is: Can i go back to the T-Mobile brand again? Again, i read some threads, but they are a bit confusing for a newby as me! Sorry!!
If i can do so, how it has to be done, so i can send to T-mobile or HTC itself so they can have a look..
Thank you very much for your help!

Same problem... have you figured it out?
thanks
dennis

any updates on this? same problem here.
tried hard reset, soft reset, reinstalled new ROM, flashed back to TMOUS stock rom... no go.
if i do a manual search for networks, HD2 finds them, but can't register.
phone connection is ON.
band set to Auto.

There is a thread similar to this on this forum about a month ago. They found out that that the phone was registered as stolen and the ieme was blocked. There is nothing that you can do about it.

has anyone found a solution to this problem yet?

My gf just started having this problem today. She's had the phone for almost 3-4 months now, so I don't understand if someone mixed up IMEI's or what?
The phone won't register onto T-mobile... this sux! and its not even stolen...

did you call t-mobile? Call 877-453-1304 and tell the automated moron "PDA" and it will transfer you to smartphone tech support.

Hi,
Same problem here, bought the mobile on eBay from Portugal , was working for weeks, since this morning can't register in Sweden anymore..Sim works fine in my old phone and HD2 finds networks etc just can't register..
How i can check is it stolen?

Problem
Same here, search finds 3 and O2 networks, but can't register these two different cards... Anyone solved this problem?

[Q] Wildfire: No Service

I was wondering if anyone can help me.
I recently flashed my phone which I have done many times. I then installed beautiful widgets from a apk off the net. Once I had decided I likes the software I deinstalled it and ever since I have been unable to get network service on my wildfire.
Whenever I try and connect to a network I get:
'Unable to connect to this network at this time please try later'
I am currently on baseband version 13.53.55.24H_3.35.149.25 but I have also flashed later radios and still have the problem.
I have also checked the phone information settings and radio is turned on so unsure where to go from here.
The phone is also unlocked to any network but I have tried a Orange, Virgin and Vodaphone chip and none work.
Cheers for any help ;-)

i was in touch with beautiful widgets developer a few weeks ago, and he mentioned there were 13 different pirated versions that they were aware of, and they were having troubles with them. the first thing he wanted was my google checkout receipt number, i wonder if you have picked up a virus somehow, with a malicious copy.
have you tried restoring a nandroid backup?

Hi
Yes I ran a nandroid restore and I still have the problem. I have also been into the phone's testing menu, phone information and it wont let me select radio band just comes back Set{Automatic] Unsuccessful ;-(
Tried numerous Roms and still the issue.
Will I have to totally flatten phone to get this working?
cheers

Have you checked your apn settings?

I have checked the APN section and I have one for orange internet and one for Orange MMS. I have looked through these settings and everything is blank except when I get to the MCC section.
One thing I have noticed is when In restore or use a new ROM I still have my details for Wireless setup etc so is it really doing a full wipe of settings?
Cheers guys

I have just spoken to Orange and they have informed me that the phone has been blacklisted hence no service. I have had this phone for over 6 months and now they decide to blacklist it even though I paid good money for it and it wasnt stolen...Nice!!!!!
Thanks for your help anyway guys much appreciated

why has it been blacklisted, and how?

The phone has been blacklisted by Virgin as stolen just recently even though I bought the phone over 5 months ago with original Virgin Chip, booklets etc. I have spoke to Orange (my own network) as the original owner is obviously trying to maker a claim which is indeed false.
I am in process of writing a letter to virgin explaining my predicament but I dont expect anything positive of the outcome. Last time I buy anything of a Forum all my own mistake to be fair!!!
Bought a Samsung I5800 just get me back up and running as the wildfire is now just sat at home awaiting to hear what Virgin say as I may sell it as parts.
cheers guys ;-)

SIM error

A few months ago I purchased two LG Optimus 7 E900 phones from Germany, on eBay. They were both Vodafone.de branded but that was easily removed after following easy-to-follow instructions on here.
I then signed up for two T-Mobile accounts for the phones and they have been working perfectly ever since. Sometime this week, both phones are showing a 'SIM error' and give the following message: The SIM card is missing or invalid. You can still make emergency calls if your mobile operator supports this.'
I have taken both SIM cards out and swapped them with other T-Mobile SIMS and I am getting the same message, although the SIMS from the phones work fine when popped into other phones! This morning, I phoned LG and they said that I should phone Vodafone and ask if they have locked the phones! As they were Vodafone.de (Germany) branded, I am not sure if they will have a clue or not.
Maybe I should go out and buy a Vodafone UK SIM and see if it works? But I assumed that if the phone was network-locked, it would ask for an unlock code?
Any ideas?
Mattresso

I just phoned LG and spoke to one of their support techs. He said that because they were bought from Germany and were Vodafone.de branded, there is nothing they can do. He advised me to send them back to Germany!! I told him that I was going to chuck them in the bin and he agreed. So much for customer service, eh??

Right, work this one out!
I decided to reflash the FW on the phone and get the thing working again. The LG Optimus 7 E900 original ROMS thread was followed to the letter and I successfully installed the Europe Open FW.
So, on completion, I slipped in the T-Mobile SIM card, only to be met with the SIM error message again!!!
Right, I am off to try the UK ROM and see if that works. If it doesn't I am off out to buy two iPhones!
Any ideas?

OK, now my head really hurts!
One of the phones has done a full reset and has the UK ROM installed and it works fine with the T-Mobile SIM installed. The only problem is that now it will not connect to any PC or Mac that I have.
The second phone has been reset and flashed with the same UK ROM. Unfortunately, this phone still shows the SIM error but it can connect to my PC and Mac!!!
Now, I have little/no knowledge of these matters but it seems to me that the problem/solution lies with the USB settings within the phone?
As part of the above instructions, it is suggested in post #78 that I should:
6. Go to Menu then 7.Engineering 3.Port 1.USB Switching Setting then select 2.QC Composite, change the driver for the USB, reboot the phone
Anyway, I followed this method (not sure if done on both phones) but I am not sure if anything needs reverting on completion of the flash.
Does anyone know?

It has to stay QC Composite!!
Going to try the SIM error phone again using the same FW and QC Composite selected!

Success at last!! Not sure why the hell it went tits-up to start with but I assume it must have been a wireless update from Vodafone.de?
Anyway, both phones working. Thanks for the help!!

I'm not sure we helped, but I've been intersetd in your story. Haven't had your issue myself, but I know a few others have.
So was flashing both phones what solved it?

Ensuring composite QC is selected, the SIM is removed and that the correct ROM is used are the three rules, it seems.
I'm convinced that it was a wireless update from a different carrier is what caused the problem. Anyway, it's sorted now, thankfully!
If you need any help, give me a shout and I will try my limited best.

Not really related to this post that I started but is it possible to connect my iPad to the phone (tether?) and connect to the web via mobile internet??

Of course you can - just update your Optimus 7 to the latest WP version via Zune, and enable Internet Sharing from the settings. This will make a WiFi network with a password for your iPad to connect to. Browse away

I had a problem like this too. Last night I plugged my phone into my PC to sync music through zune and was prompted to install an update. Installed the update and my phone works!
Running OS version: 7.10.7740.16 and finally have service!

same issue
I'm having the same issue. Phone is stuck at PUK code even though sim works in other phone. It is a UK Vodafone phone.
Can you give step by step guide of how you got yours to work?

Hmmm. Again, I am flummoxed!
My daughters' phones are both showing the SIM error message once again.
After previously flashing the phones with the UK open FW, the phones worked perfectly, until today! We all spent Christmas and New Year in Orlando and took the phones in the hope that a US sim would work in them. The sim didn't work in either phone and I resorted to buying a $20 Nokia! Worked fine too.
Anyway, on return to the UK today, the phones were powered up with the UK sims fitted but both phones are showing SIM error - No SIM.
I really am very, very close to throwing these phones in the trash! Anyone have any ideas why this has happened and will I need to re-flash them (again) in order to get them working??

I had this a short while after I was upgraded through Zune. I sent it into Vodafone and they fixed it, but it'll probably have to be the place you bought it from...

I bought the two of them from Germany via Ebay! They were both Vodafone.de branded but not locked but I re-flashed them with an open, UK firmware. Everything has been fine since the re-flashing, until now!
I have been in touch will LG and they said they will pick them up and repair if:
They are still in warranty
They have not been damaged due to dropping, etc.
They were purchased in the UK
All boxes are ticked apart from where they were bought. Surely a warranty must be valid anywhere within the EU?? Anyway, i am going to play dumb with LG and hope that they will reflash them....if not, I am definitely launching them into the sea! Damn fed up with them now and too much information on them has been lost too many times.

Almost certain mine wasn't within warrenty, they still did it for free. Mine happened very close to an update so I thought perhaps the update caused it. In that case they might say things along the lines of "you must meet certain conditions", but at the end of the day they'll quietly repair it free of charge. We'll see.

I sent both phones and received them both today with a letter titled, 'We've checked your handset and cannot find a fault'.
OK, so I immediately popped in my T-Mobile SIM and got the SIM Error message once again!!!
I'll phone them in the morning. If I get no joy, it's new phone time!

Sim error
I'm having the same problem after upgrading to 7.10.8107.79, try so many ways and still stuck with error. Can anyone help me, maybe telling me how to change FW, Rom Etc.
Here's what I have
OS Version: 7.10.8107.79
FW: 1.1.8.10
Hardware #: 1.0.0.0
Radio Software: 1.1.8.10
Radio Hardware: 0.3.5.0
Bootloader: 1.5.1.0
Thank you in advance
Update:
Problem detected, I just realized the connector pins on sim slot, one is broken not allowing full contact with the sIM card.

Hi, mattresso!
Thanks a lot for sharing the exprience which help me solve the "SIM error"!
I got my E900 from Hongkong last year, and the "SIM error" issued a few days ago. At first I tried to reflash the FW with Hongkong ROM, but it did not work. Then I found your thread and followed your way to install UK ROMs from Orange and Vodafone. Both of them make my E900 work well again.
Sorry for my poor English and thank you again.

No signal on stock rom

So,
I was using my XT-1563 on a CyanogenMod in one of my local carriers. I bought a new phone and decided to sell this one, so I went back and installed stock rom. So far everything was ok.
The problem came when the person that was buying it tried to use her simcard. The phone didn't show any error, but it never connected to that network. Then I tried another sim from different carrier and it didn't work either (but it does work using my old simcard). It recognizes there's a new simcard, but fails to connect, only allowing emergency calls.
I've been trying all day to fix this. I have flashed nearly half of all the stock roms available, obviously starting with those from my zone, but so far none has worked.
I also tried the simcard into my new phone and it works just fine.
So, I know the following:
- The simcard is ok.
- It's not a signal problem (I have tested it in different parts of the city and zones I know have very good signal).
- The phone works using a simcard from one carrier, but not the others (and it doesn't ask me for some unlock code).
Thanks in advance for any help, it'll be greatly appreciated.

So, did you ever carrier unlock the phone? I realize it's not asking for a code, but you never said you actually unlocked it.

At this point I'm not 100% sure.
When I bought the phone it was supposed to be unlocked (I got it from someone else) and I'm pretty sure it was, because it was originally bought for one carrier (Entel Chile) and then I used it with another one (Wom Chile). By law, every phone sold in Chile since a few years is mandatory unlocked and this one is not that old (2015).
Right now it only works with Wom Chile, even tho I've installed Entel's stock rom. I think it's some baseband issue from what I've read, but I can't be sure.
P.S: Sorry for bad english.

Yes u r right
i used cm14 on xt1562, i'v feel my network was drop around 30-40% specially on Reliance JIO 4G VOILET.
Over all - rom is good for enjoy but not for stability
