Newbie here to the forums, thanks to all who contribute; a magnificent effort by all and it's much appreciated :good:
My question is this; I have an O2X native to Fido Canada. I had unlocked the phone while on stock firmware. For a bit of fun I decided to try updating the phone with CM10.1. All went well (thanks in no small part to the guides in these forums,) but found the nightly version was giving me very poor battery performance. At the same time I used the phone briefly with my Rogers sim card. Calls and sms of course not a problem. But I tried to input the Rogers APN for data support, and I found it wouldn't save the new APN. Didn't think too much of it because I was going to downgrade to a stable version of CM anyways.
I downgraded to CM7. Fun and easy, happily going along I thought it was time to set the Rogers APN; again I couldn't save.
I downloaded Tweeker MMS app to automatically set the APN, what a great concept!!! However, it gave me an error saying I had no SIM installed and no gsm connectivity. Hmmmmm...
After some other playing around and scouring Google for answers, I came across the SIM PIN in settings-location and security. It shows that SIM PIN is set, though I've never had one. Even without a sim installed, it was asking for the PIN.
I tried a different sim without a PIN set, same thing.
Tried a factory wipe/reset. Same thing.
Tried a different ROM, revert to stock, uprade, downgrade. Same thing.
No matter what I do the Security is always set to have the SIM PIN, but it never asks me to put one in. It will not, however, allow me to set a new APN while this setting is there. Any attempts at changing the setting just result in "incorrect PIN".
Is anyone out there familiar with this glitch? Is it a baseband issue? Kernel? Poltergeist? Evil Gnome?
Any suugestions would be appreciated :fingers-crossed:

My Nexus was on 5.0.41, all working sweet, then it stopped "finding" the network. No update, flashing or anything was done prior to the problem.
I tried a SIM from another provider, but still - the "No Service" is written on screen, and when I try to search for networks, it says "Error searching for networks".
I then tried the following ideas (nothing helped):
- Reflashed the Radio image.
- downgraded the Radio image.
- Upgraded it again.
- Flashed the Stock ROM (unrooted and rooted).
- Flashed CM5053.
All was done with wipes as needed.
Any suggestions will be more than welcomed!
Can the device just get bricked like that? with no reason?
It sometimes identifies the SIM's provider (Orange for example) but always with No Service.
It sounds like your SIM card slot isn't holding the card in tight enough to make full contact... try putting a business card, cut down to size, between the SIM and the phone's frame (note, not the contacts side, but the back side) to force the SIM down onto the reader tighter.
If that does nothing, not sure what to tell you?
it didn't help
I'm Italian and I have the same your problem .. I only work in 2G GSM'...ve tried to see if you do so?
I opened another tread here Forum
You need a new SIM.
I just had this problem on Friday. The SIM some how falls of the network and your provider network will not allow it to reconnect.
I can't remember, but if I am right Orange is owned/owns by T-Mobile. Hence they have the same network.
The puzzling part about this is why it happens. This is the second SIM I have gone through with my N1, I also had one go with my G1, my sister bought that G1 and the SIM went out again. My mom bought her G1 same day as me and hers has died once. My friend has a MT3G and his has died two times now. I find this extremely annoying.
I tried every suggestion on the internet for repairing or troubleshooting a SIM. It is a waste of time. Well, everything short of dropping it in isoproply alcohol to clean the contact.
I tried a 2G and a 3G SIM on mine, and had the same result, so my problem is different.
My device just doesn't register with the network, no matter what provider or SIM generation I choose.
Can I ask for a RMA if I unlocked the bootloader?
I do not know you definitely do not pass it under warranty
Ryan then you say you clean the contacts of the nexus or the sim with isopropyl
Mine is now doing that as well and so far everything that I tried isn't fixing it. I get it to connect briefly with edge and then nothing. I am going to try a new sim tonight after work and see if that helps, otherwise unsure of what to do after that...anybody got any answers or suggestions?
I've been suffering from this... have an RMA coming but I got mine to work. Make sure you also have CDMA preferred on there or whatever the default is. If it says unknown you have to reboot the radio somehow. I pulled my battery, waited 5-10 seconds. Then i went and checked airplane mode on and off. Then i checked the service menu again. I can't remember if i had to pull the battery another time but it came back from "unknown" to cdma preferred. You can also try turning the radio on and off via the service menu. Finally select your radio bands for your region by pressing the menu button under phone information again in the service menu and select radio bands. I'm not sure if automatic is a good or bad idea but it couldn't hurt testing it if you still have some issues even after selecting your region specific bands. After this you should be able to maybe search and register or you may need to turn the radio on and off again via airplane or the service menu. I played around with it alot to get it running again.
Also I'm tmobile usa using the one for t-mobile bands. I'm not sure if CDMA preferred is a world wide setting or if its gsm or something else.. but the bands are specific to your region definitely.
a quick history of what I've done so far
Sumsung I897 captivate from ATT unlock and being used on Telus network was working great for about 4 days, then all kinds of problem started cropping up.
Phone came unlocked, I rooted using update.zip from xda, installed rom manager and started removing ATT bloatware, entered SMS and APN info which worked fine.
Yesterday I noticed that where I once got good reception I was now getting nothing and would have to drive down the street before I would get something descent. I thought maybe I'd put it back to stock with rom manager and see if that would help which it did not. It actually made it worse, decided to go all out and use the Odin3 one click downloader just to make sure I was back to stock firmware. This didn't work either but now I can enter the SMS and change the preferred network type but it doesn't save. Preferred network type is grayed out and even though I can change it it never save same as SMS.
Now I can't hold connecting in my living room where my wifes Milestone gets full bars. I tried taking the phone to where I had the best signal and change the preferred network, SMS, and set the network operator but it doesn't save any info, can't find on operator half the time on manual or auto and gave me an error and logged it to #*9900#
I've been at this for 2 days straight and can't figure out how to get it right back to stock, it seems to keep hanging onto the same preferred network and not saving anything I enter.
What can I do to get back to stock, and it has to be something that wipes everything clean, clean, clean, because even the GSM disconnects stay logged under *#*#4636#*#*
***I desperately even tried pulling the batt and SIM card for the night in hopes that would do something.
So, if I'm understand what happened correctly, you bought an unlocked Captivate, rooted it, deleted some bloatware, entered your Telus APN info and everything worked awesome for about four days. Now everything has gone down the hole. Is that right?
If that is the case, then we need to figure out what changed. Using Odin3 would have definitely put you back to stock/unrooted your phone, I don't think you could go back any further than that. If I were you, I would act like I first got the phone. As in, I would do everything you did to it, as if was day one. At one point, everything worked fine. Try to recreate that. You can always look into exchanging it or perhaps Samsung customer support can give you a little more insight to what's going on. Here's the number if you want to try them out.
Samsung customer service - 1.800.726.7864
Thanks, I've gone through the process a few times today from start to finish trying to figure it out ... maybe some of the problems aren't real problems and just limitations that I didn't know where their. I've since flash with odin3+re-partion to the bone stock i897UCJF6 as in not the one click method. It loaded fine but still have the same issue, I can't set preferred network type or get it to keep the number entered into SMSC. I think if I can get passed that I'll be be one the up side of winning. I keep noticing that the log of GSM disconnects never clears or the usage statistics under *#*#4636#*# , I'm thinking its in the same area that other bad data is being held onto instead of being cleared when flash firmware or factory reset.
Is anyone able to change preferred network type? maybe I was never able to change it but I think I should be able too.
I may be wrong in assuming this but I don't think ATT is going to be interested helping me connect one of their handset that I'm trying to use on foreign network, but I could be wrong and is an open option.

used this to lock my phone to WCDMA only so that problem is solved
*** never mind posted to soon it still didn't stick after rebooting
be carefull using the service menu as I have no idea what most of this stuff does
I got the SMS service number issue fix by taking out my sim, swapping in another known working sim from the same network, setting the service number, pressing update and then swapping back. Before every time I tried to update the service number it spit out an "update error" can anybody tell where the SMS config data is stored? on the phone or sim.
The only problem I'm having now is with reception which maybe fixable if I can set the preferred network to WCDMA only. But the button for that option is a light blue colour vs other phones that I can change this setting on. Does the blue mean anything like a locked function or something that set by the firmware as unchangeable?
Hi All,
I had a strange issue happen to me last night. but first some background. I bought a Bell locked phone and unlocked it to work under Rogers. It worked for well over a month without any problems. I never flashed any roms of anything like that, just rooted and unlocked it. All of a sudden last night the phone would not recognize my rogers sim card anymore. I tried to enter in the unlock code but it would not recognize it. I went to the APN settings and they were blank. Entereing the correct APN settings would not matter as they would not be saved.
I tried formatting the whole by doing a factory reset but that did nothing. I tried searching for fixes but the only thread i found that had any solutions was this one forum.xda-developers.com/showthread.php?p=9069113#post9069113 - after pulling that file i found i did not have that paramater at all.
I now have no idea what to do and am stuck. Any help would be greatly appreciated.
any help would be greatly appreciated.
no one knows anything? im stuck with a phone that can do everything except make phonecalls
was lucky enough to find this topic:

APN setting wont save
Hello
I have recently loaded the FRX04 updated os for my touch pro2 (rhodium) and cannot seem to get an apn settidng to save therefore cannot get a mobile network to work.
I am currently running off wifi but cant make outgoing calls or do pretty much anything with the sim card
I have tested two sim cards in the phone (which was originally on vodafone) but when it was running the windows platform it is fine with any network.
I read somewhere that it may be a bug in the mnc field which is why it wont save a new apn?
I have looked at downloading the SGS unlock tool but i dont think this is the issue
any suggestions will be appreciated
Hello,
I have problem with SIM card on my phone. I'm using Temasek's CM 10.1, Kowalski kernel, and V20I-EUR-XX baseband. When phone boots, I normally input my PIN, but it doesn't connect to network, I have to go to Mobile networks and Choose operator automatically, then it connects. I can call and send messages normally, but when the call hangs (me or the other side) it says SIM card error (something like that). Also I can't save APN. In APN settings there is nothing, and when I create APN manually, I input everything and press save, but it doesn't stay, APN's remain empty. I use micro-SIM with adapter, because my operator couldn't get me normal SIM at a time. I'm on Croatian provider VIP. Everything normally worked with micro-SIM from Tele-2 provider (although on CM 10, and CM 7, didn't test it on CM 10.1).
Is it related to my SIM card or SW (ROM or baseband)?

Not sure if you read my post, but I think we are having the same issue regarding the APN, etc.
Not been able to solve mine yet, perhaps together we can put out enough info that someone here can offer a solution? I haven't changed the baseband or kernel on their own, only went from stock 2.3.3, to CM10.1, then to CM7.2.
Are you able to remove the SIM PIN? If you remove the SIM PIN from security, are you able to save APN?
Does your phone access data with the native SIM card the phone was originally locked to?

It seems that PIN is already disabled in Settings-Security-SIM card lock settings :silly:
I called my old operator and they told me my phone was sold locked, and new operator told me they can't help because I didn't buy the phone from them. But then how it works now for calls and messages?
I don't have any other SIM with me so I can't test it with my phone. You say going back to CM7 didn't help? I guess I shouldn't try that then.
Maybe flashing stock ICS would? Any other suggestions?

I haven't tried stock ICS yet; maybe it would? I will try that tonight.
Mine shows the SIM PIN on, when I try to change it it asks for my old code, which I don't have of course, so I can't remove the security. Been hoping that someone else would have had experience or knowledge of what would cause the problem and have a solution or suggestion to try. The closest I came was on a different forum about a Sony Ericsson phone, but the rooting and flashing procedures are so much different I couldn't see a solution in it, though they suggested flashing the baseband iirc.
HMMMM, now that I read your reply, I can't say with 100% certainty that the phone was unlocked before I rooted and flashed CM10.1.....I had thought it was but perhaps it wasn't, and we are having a more similar issue than I thought. So the glitch, perhaps, is that it was not unlocked, the custom ROM somehow "half" unlocked it, and here we are stuck.
Okay, my only thought then is to take it back to stock everything, the most up to date I can find, then unlock it with code, and see if I can change the APN at that point. If so, I will root it, use My Back Up Root to save settings including APN (just in case so at least I can restore it that way if I can't do it manually, after)flash CM10.1 again or another fabulous custom ROM which is what I really wanted in the first place
I will try that tonight, and post you the results. Let me know if you have any (better) suggestions as well, I'm up to try almost anything at this point. Was hoping to upgrade to this for my daily phone as I'm limping along with a Acer Liquid MT that has seen better days
If anyone has a link to quickly point me towards the latest stock ROM etc. and wants to post here, I would be much obliged Might save this noob a few hours scratching his head to find what is most certainly in front of my nose already, but I digress...
Cheers
New baseband
I just flashed V30A baseband, and it didn't help. We can cross that from the list.
Well colour me confused...and happy?
I just today picked this project up again, about to attempt a different fix, again...*sigh.
Lo and behold, i insert my sim and power on the phone, and it asks me for network sim unlock.....odd because I'd used the phone with this sim before, through all my other testing, flashed different roms, etc. etc. In fact, I've used the phone on this very package, I know because there are sms messages on the phone from using it. Battery pull, remove sim and check, yup sure enough, old messages there. Hmmm...
Insert sim, reboot, asks for unlock code again. Well, what have I got to lose at this point right? As I said before, I THOUGHT I had unlocked the phone before starting this whole debacle, but wasn't 100% certain about it. Searched my email for the code since I always save them, couldn't find it. Well, in for a penny, in for a pound I suppose. Bought a new unlock code, waited for it to arrive. Input new unlock code, unlock successful!!
Reboot phone....waiting for service....(this seems like forever!!! In reality, less that 60 seconds.) Alas, I have service. And now, just to tempt fate, Apps->settings->wireless & networks->more->mobile networks->access point names..........:fingers-crossed:
I can hardly believe my eyes, there it be, Rogers Internet apn selected. It even auto-detected the damn thing!!
I can offer no further insight, I don't believe I physically did anything to arrive at this remedy. But there you go, for my part at least it's solved.
I bought a second hand GT-I9305. After the first boot I dicided I wanted to flash it with the CM nichtly. I first rooted the stock rom, flashed a recovery and then flashed CM. Now the problem is the I can't make calls. When I dial a number the phone responds with 'call ended' before it even starts.
I don't know if the phone worked to begin with, the first thing I did is flash it.
I've tried different roms now and reverted back to the 4.3 factory image. None of that fixed the problem. I've also tried putting to 2 or 3G only which didn't help either. My phone still shows an imei number.
I'm completely aware of the fact that I might have done something very stupid. I flashed android devices before but I'm the type of person who reads the manual when it's to late.
Does anyone have a suggestion on how to solve this problem?
I'm usint T-mobile on the EE network in the UK.
Problem still unsolved, more information
I'm giving some more information as the problem isn't solved yet.
I'm on a Pay as You Go sim that works fine in another phone (HTC Desire S). I've now also try to downgrade to 4.1.1 but still no luck. I've also tried different sims but the problem occurs with those sims as well.
The phone looks to be registered to the network, at least that's what it shows. Also, data works, I get a 3G and H+ connection,
I'm more than happy to provide more information. Any help is greatly appreciated.
SIM unlocked? Google xda sim unlock GT-i9305...
Phone not locked
Thanks for your reply. The phone is already unlocked.
IMEI blocked? If you're in UK try www.checkmend.com/uk/ it'll cost you 1.99 but might save you time & effort...
