o2 xda executive sim card problems

hi im due to buy an o2 xda executive heres what the guy has put in the advert
( It has one significant fault which means the phone functions do not work, as it has difficulty in recognising when a SIM card is inserted. I have used it with O2 and Vodafone SIMs and it was sold to me as unlocked, but most of the time now it says a SIM is not inserted, even when it is.)
what i want to know is does anyone know if this is a common problem and is it easy sorted is it ususaly software or hardware related and is it worth buying if the price is right then geting fixed or is it a problem easily sorted something i could do myself
btw i need help quick if possible before it sells
thanks

Talking about phones in general.. this is usualy a hardware problem.
Perhaps you could find out how old the unit is and (if under a year) claim off the warrenty?

thanks
ahhh cool thanks for your reply

i was just thinking the guy emailed me and said he reset the device to wipe all his info off it and now its showing that it has a sim card in it but he has done this before and it goes back to how it was (showing no sim card )
my question is wouldnt this point more towards a software problem rather than a hardware problem

help update please
right i got the thing now it wont work with an o2 sim
so i popped a vodaphone on in and it worked for a while
then i took sim out looked at sim holder and sim contacts and all looks perfect so i put the vodafone sim back in and im back to the invalid or missing sim card error what next guys ?
when the device boots up i get these three things on the screen
r 1.04.02
g 42.37.p8
d 1.13.82 wwe
i suppose thats the 3 things you were teling me about ?
could someone point me in the direction to the files i need and the order i need to put them on ?
and mabey a quick readthough or point me in the direction of a post relating to this problem

i get similar things when my xda boots too. I am pretty sure everyone does. Does it display an error message with the O2 sim in? Providing the phone is unlocked to all networks, this shouldnt cause a problem.
TBH I cant see that it not reading the sim could be a software problem (someone please correct me if I'm wrong). Even though the contacts look clean, you could try cleaning them anyway. I use the rubber-end of a pencil, or an elastic band if I cant find one. But dont go rubbing the contacts away altogether.. lol

ah right sorry ignore the (suppose thats the 3 things you were teling me about ?) bit in the post that bit was for another forum the reason why i typed all the info on where the thing boots up is because someone told me the radio may be corrupt and to reinstall or install the newest one so thats why i typed all that info and i was wondering where to get the files from in what order to do them and was there a sticky and where is my bloody pencil with a rubber on it !

Just to confirm, you ARE using a 3G sim, right? I don't think it works with normal sims

3g ?
no im not using a 3g sim but the vodafone one i tried worked for a while and that was not 3g i have also cleaned the sim card contacts and the phones contacts to no avail
i have also just unlocked it using the HTC_Universal_Radio_for_SIMunlock_v0.00.00 file
still wont recognise my sim
someone mentioned elsewhere that the radio stack was possibly messed up and i wouldnt be able to use the wireless connection ? but i can so that rules that out ? so its possbily hardware related but all looks ok inside

FYI mine worked fine with a normal O2 sim, bar the 3G stuff ofc

suggestion
try putting a piece of paper between the sim and the battery to push it down a bit. Its a longshot but I know of someone who had a similar problem and it was solved like that.

Hi
That's right try to use a piece of paper stick right behind the sim card to push aginst the sim card to force a good contact, but before doing so try to use a Q tip and small amount of rubbing Alcohol to clean the sim slot metal contacts because from time to time the metal contact might being oxidize and preventing it from a good contact with the sim card. If after trying all this still not work than you might want to try flash it with a new Rom.

any ideas what next please
hi
i have tried the paper behind the sim i have tried the cleaning of the contacts and i have upgraded the radio so as the title says any ideas what to try next as none of thme make my universal think theres a sim in it it just says missing or invalid sim ?
also at the moment my radio is 00000000 so its unlocked but if iwanted to upgrade it whats the best one to upgrade too ?
is it either UNI_radio_1[1].08.00 or is it best to upgrade to UNI_radio_1[1].09.00
and what do i do with the nbf file ? is there an upgrade program please

update
hi all
today ithought i would try a vodaphone sim out of my works phone in the universal and after 3 resets it worked the phone kept a signal for about half an hour then went back to the invalid or missing sim error so i put it in flight mode then turned flight mode off and the thing worked for the next 5 hours but now after leaving it alone for half an hour im back to the error ?
anyone any ideas please

another update
hi
last night i flashed my universal with the sim card in and when it booted up the phone was working there was a strong signal e.c.t. it stayed on for hours but when i got up in the morning and checked it it said missing or invalid sim card so i put it in flight mode then turned flight mode off and it started working again it has now been on for like 3 hours so has anyone got any ideas why it keeps coming up with this missing or invalid simcard error because i would like to get it fixed
i havnt got a clue what im talking about but could it be the antenna or something ? or is there something else i could try
thanks for all your help so far

after i flashed it it can stay on for hours even the full day but then i get sim isnt inserted error
plz plz plz help !

[Q] [HD2] Antenna exclamation mark and 'SIM card is missing' issues

Hello all, I bought a used HD2 off CL (USA), hoping to unlock it (if locked) and use it with my ATT prepaid sim.
Outwardly, the phone looks fine and everything about it works quite nicely, EXCEPT that when I insert my SIM card and start the phone, it shows me an exclamation mark on the antenna icon. When I disable all wireless connections and then re-enable it, the icon now changes to the SIM card icon with an 'x' next to it, and I am shown a screen with a keypad and the following message: 'The SIM card is missing. You can still make emergency calls if your service provider supports it.'
Thinking it was a ROM issue, I successfully loaded the latest ROM from [showthread.php?t=789506] but it did not resolve the issue. There is no issue with the SIM because it works nicely with my AT&T Samsung a607. There are no signal strength issues either.
Please help!

Can someone please provide some insight on my situation? I hope I haven't posted in the wrong forum; if so, mods may move it to the appropriate place.
Any advice on diagnosing the issue will be appreciated; I don't even know why the phone is acting the way it is. Many thanks!

Wait a moment, so your device isnt already SIM unlocked? Sounds to me like you need to go ahead and get an unlock code for it, then navigate to the \Windows folder and hit up the program called "simlock.exe" and input your unlock code, then try your ATT SIM again.

Thanks much for the reply. Other phones usually prompt for a SIM unlock code by themselves... why doesn't this one?
Running simlock.exe from Windows does give me the message "Network is locked, please input unlock code". Before I buy the code, I want to make sure that there's nothing physically wrong with the phone. It should give me at least *some* sign that my SIM is being recognized, but rejected due to network-locking, no?
Thanks again!

See thats the thing. With a foreign SIM card in the device, IF LOCKED, simlock.exe should run automatically on startup and ask for the code....so honestly I do not know if your device is messed up somehow, or if its just being wonky for the sake of being wonky. Perhaps you might want to flash a new Radio ROM and see if it then recognizes your SIM. BE SURE to NOT flash one with .51 in its name.

Thanks again. Can you point to a thread with detailed instructions for flashing a new radio ROM for my device? I found many threads while searching and I am confused. I don't want to choose the wrong instructions and brick this device; I haven't done anything of this sort before.

Look at the top of these forums for a stickie by Snarksneeze that will teach you everything you need to know.

Hi again... I don't have a spare 8GB MicroSD card lying around. Is there any way I can do this flashing over USB? I did read that there's a risk associated with flashing over USB (cable yanks, power loss, etc.) but I did flash the newest ROM without any issue, and hopefully I can do the same for the new Radio ROM.
The Radio version shown in the 'About Phone' section is 2.14.50.04, btw.

You can use your 16GB that came with the phone, or any other one for that matter. That requirement is more of a recomendation really. I have flashed with my stock 16GB many times. And yes, you can do it via USB aswell.

OK, so I have more information about the problem. I got the phone unlocked (I heartily recommend 'fastunlocker' on eBay) thinking that it would solve the issue... but it didn't. But, on a lark, I tried my friend's post-paid T-Mobile SIM in the HD2 and it worked! My AT&T pre-paid SIM does not... can this be a problem? The damn thing works nicely in other (unlocked) phones.
Is anyone else successfully using a AT&T GoPhone (prepaid) SIM on a TMOUS HTC HD2?

It may very well be the problem then. I have heard that some phones are incompatible with pre-paid SIMs.

God, that would suck donkeyballs. Can someone confirm that an unlocked TMOUS HD2 does not work with AT&T GoPhone prepaid SIMs?

had this same exact issue and realized that one of the pins in the sim card reader was stuck in the down position. I poked it with a small screwdriver and it popped back into place. works like a charm now.

Thanks for the reply. Are you sure this is the issue? As I mentioned in a previous post in this thread, my friend's T-Mobile SIM works nicely with the phone.
EDIT: Also, are you using it with an AT&T GoPhone SIM?

Bump... anyone?

Final bump: maybe I am SOL. :'(
Is anyone successfully using a TMOUS HD2 with an AT&T Prepaid (GoPhone) SIM?

Give it some time. Sometimes threads at XDA stay dormant for months and then suddenly BAM! a breakthrough happens.

I would say its your sim. How old is it?
I had the exact same problem. I bought a HD2 off cl and put my sim in and got the no sim message and exclamation point. I was using a sim from the voicesteam days but guess what it worked just fine in the Nexus one I had just gotten so I figured it had to be the phone. I finally used a friends sim and it worked fine. So I would turn the phone off in settings then slip his sim out with the battery still in and put my sim in and turn the phone back on. Guess what, it would work for about 10 min then it would suddenly go back to no sim message. So I went and got a new sim from T-Mobile and walla works like a charm. So try what I did and if you end up with the same problem try a new sim from AT&T. I don't know what is different about the HD2 but there something about the older sims that it doesn't like.
Hope that helps!

Hey... thanks for ther reply! My SIM is brand new (about two weeks old). I will however go to the AT&T store and get it replaced to see if it fixes the problem. Thanks again, I appreciate it.

Dear look my problem...

[Q] Please help! I may have ruined my phone

Hi all,
I've recently bought an HTC Legend from Virgin mobile, unlocked it, and now trying to get it to work on Rogers. After I unlocked it, I tested the phone by placing a call. It worked.
Then I got excited and decided to root it and load a custom ROM. I did not read the comments about the ROM and it turns out, the ROM changed my radio. When I go Network Operators on the phone it now says, "Your SIM card does not allow a connection to this network".
The ROM I used was Rodriguezstyle MoDaCoMoDrOm V2.3
I thought I lucked out and found the Bell RUU from Shipped ROMs but that didn't help at all.
I got too excited when I first received the phone and didn't take down the radio info before I starting messing about, which was stupid on my part.
I am freaking out a little and not sure what else to do. I had asked a friend to bring this phone over from Calgary, AB for me because they don't sell them in Winnipeg, MB where I live so bringing it back to the retail outlet is going to be pretty difficult.
Please, please, please help me. I apologize in advance if I am posting in the wrong spot.

You may be able to return for "warranty" purposes. Just lie through your teeth

Or you can do it the hard way. Just flash all the radio that was released. Try one by one and you might hit the spot. Try 7.08.35.21.

Haha! I wish I could. The retail outlet where the phone was purchased is in another province and is about a day's drive. They don't sell the device in the city I live in.
...although I could give it a shot here and ask them to ship one over? I'll save that as a last resort

I think I might have to try this method. Do you know if there is a repository of all the radio released for the Legend?

I've flashed the radio suggested, 7.08.35.21, still nothing. I was reading in another thread that it could be my SIM card? Strange how I was able to place a call when the phone was first unlocked. ...but it IS about 3 years old.
I'm not sure what else to do. I just may have to plead with the retail stores here. Hopefully they can ship me a new one

Whoops! I meant the SIM card. Sorry about the mix up.

I just got off the phone with Rogers Tech Support to see if there was anything wrong with my SIM. He said that the symptoms I am having seemed similar to that of a locked device ("Error while searching for networks" and "Your SIM card does not allow a connection to this network" when in Settings > Wireless & networks > Mobile network > Network Operators).
He mentioned that by flashing a new ROM, that could have re-locked the device. Sounds strange to me but if this is true, how do I find out which carrier the device is now locked to? I am now running the rooted ROM found at the root tutorial TheUnlockr.com.
The phone is not prompting me with an unlock code input like it did the first time around. Is there a way to bring up that prompt again?
Please and thanks

Hi all,
I hope everyone had a great holiday.
A few updates:
- tried flashing different ROMs
- tried toggling radio and autosync
- tried flashing a new radio
- tried using stock Bell Mobility RUU
- contacted Rogers and got them to reset me on the network
Still nothing, not even voice. I've been obsessing over this and it's driving me a little nuts.
rajasyaitan has suggested flashing all the radios that were released until I hit something that worked. Is there a repository out there?
I don't know why, but it never occurred to me to ask for the stock Virgin Mobile Canada RUU until now. Does anyone have it lying around somewhere or knows where I can get my hands on it? I can't find it online anywhere. If not, is there a way to pull it from a phone that is running the stock ROM? I'm not sure if it is the same as the Bell Mobility one but I thought I should start from the very beginning.
Any help will be greatly appreciated.
Thanks

Please my phone is having the same exact problem, it's not working! I'm with Virgin Mobile Canada and I cannot connect to my carrier telling me my SIM card is not allowing me to connect to them! Please someone help! I used this Rom called Stock Froyo ROM for the HTC Legend with Online Kitchen from Modaco.
And when I loaded it, it wouldn't let me access my settings and then I loaded my backed up Rom, and now I can't connect to my Mobile Carrier. (Virgin Mobile Canada) what should I do?

Just a thought here, but is it possible that the phone is SIM locked again? When you unlocked it, did you have to flash another radio FW? Did you try "unlocking" it again?

do you have the phone set to gsm only or something like that? should be set to wcdma only (for bell/virgin/telus)

Actually my phone is connected now, I had the same problem, I did something with the recovery before the problem was magically fixed, I went into recovery, and went down to "Backup/Restore" and I went to "Restore Google something sys..." (Restore NOT backup) and when it was done, my phone was working again, but I was on a different Rom other then the one that caused the trouble. That's what I did and it might have worked because of that I really don't know. And my phone is on "GSM/WCDMA auto", and it's connecting just fine.

[Q] Please help me, I'm having problems

Hello evreyone.
I'm having a bit of a problem with my Samsung Omia II I8000.
I just got it from a friend of mine, and for 24 days or so it has been working great!
Really loved the phone untill the next thing happened:
I was playing a game on it, and I suddenley saw my phone didn't have connection with my provider. (Vodafone NL)
From that moment I thought it was strange, so I did a soft reset.
Nothing happend, still no connection, I did a hard reset.
Again, nothing happend, then I did a clean reset, and as you can guess... Still no connection.
I don't know if this sound fammiliar to you, but can you guys please help a man out?
Last thing i'm waiting for is buying a new phone.
Also the other things I tried:
-Opened the case, looking for the antenna wire, but it was still attached.
-Looked for a firmware update by looking at new pc studio, but it had the latest installed.
And somthing diffrent that might help you out, my wifi is working great, I don't now if that matters or not, but just to let you know..
Again: I REALLY,REALLY hope you guys can help me out!
Greetings, Olav

Have you tried either your sim card in a another phone to rule out the fact that your sim card is dead. And also have you tried another sim card in your phone just to verify that its not the sim card?
I will do these two things first before proceeding to do anything else.
I had a similar issue with my phone and was able to solve it by changing the sim card.

[q] invalid sim error

Ok so since nobody wishes to answer in direct rom forums, I'm going to ask my question here. I was very successful with Android as that's easy. Installing WP7 was also a breeze and the whole unlock thing cool. Problem is no matter what WP7 rom I try I always have an "Invalid Sim" error emergency call only. I am in canada with my provider being WIND mobile. Am I correct in saying that windmobile sims just dont work with windows mobile? or is anyone else having the same issue or is there a fix for this. All i am asking for is a simple "proper" response without the flaming. I've searched. I'm not new to xda but i am new to wp7. thank you
WOW Ok..

Can you borrow a different carriers SIM (from friends / family / colleagues) to test with, see if that works? That would help to understand if it is your SIM or the install of WP7. TBH it does sound like it is the SIM that is at issue.
edit: I just checked and the HTC connection setup app (from the market) does list both Canada and WIND, try it

Hey first of all thanks for a response. I'm also thinking it's not the sim (i'll try my wife's rogers sim card when she gets in from work.) because it works perfect with winmo 6.5 and Android without issue. I tried 3 WP7 roms and none worked with the sim..which boggles me
OK so after using my wife's rogers sim card it worked perfectly so it IS the wind mobile card that is not compatible with wp7. I guess i need to find a way to make it compatible if there is one.

I've gotten sim errors on my real hd7. To fix it, I have pulled the battery and reseated the sim. You might try to get a new sim from your carrier, just tell them your old one is acting up.

Tried that a few times and figure it may just be my SIM period although it's strange that it works without error with the android roms. But yeah imma go into Wind and grab a replacement and see how that goes

Did a new SIM help you, or did you do anything else?
After I have entered my PIN my sim is working fine, but after some time it says Invalid SIM.
/Regards Lars

I think it's an issue with the Roms. I think there are a lot of people getting the invalid sim error. I use the BlackSideSeven rom and I've seen several posts about it in the thread. There are also several other threads started about possible fixes and stuff.
Here's a link.
The easiest way to resolve is to turn on airplane mode and then switch it off. It doesn't stop it from happening, but at least you don't need to reboot.

Error in Android as well
I am having the same problem with MDJ Froyo 2.2. When I reboot into winmo 6.5 great signal all fine. I did notice that the simm card did move in the slot possibly bad connection. Now that I reseated the Simm all is fine. I also just read about antenna issue with the HD2 going to open and fix it to see if that helps.
