Locked and goosed?

Hi can anyone help me please?
I recently bought an htc one x, it had no sim card and i was told it was unlocked for any network, i have flashed the rom that has the snake on (cant remember the name). When i put a sim card it just doesn't seem to register at all, It seems that the airport mode is always in a state of turning of and the wifi wont turn on, i have tried to get the imei but when i do this there is no number at all just the word IMEI: Is this phone goosed? Would it be worth selling to another country where it may work so i can get some of the money i paid for it back?
Thanks in advance.

Mate, I'm afraid you have been tricked. What you described sounds like a serious hardware problem to me. As long as the phone accepts the SIM card it's not SIM locked, alright. But not being able to get out of airplane mode, or not being able to turn on wifi, sounds like it's seriously f****d up (pardon my language!). I suggest you see the service with it. Passing it to somebody else certainly won't solve the problem with it (only your problem!).
Cheers!

I wouldn't jump to conclusions there!
OP I recommend going back to stock and see if the problem is still there. An error in installing ViperX is always possible. Let's just hope nothing was wrong before you unlocked your bootloader. Otherwise you won't be able to get warranty if it's a hardware problem. I always test any electronic device for a week or two before I screw with it.

Sim Card Removed - Restart/Reboot Phone

Hi there
i own a galaxy S3 TMobile version for 2 months now.
I recently update on last rom and since then i am getting the following error.
Sim card removed. Replace the sim with a valid sim and restart/reboot the phone.
I am not really sure if i wrote the message exactly as it appears but thats the meaning of it.
I have unlocked the phone to use it on Greece.
I have the same sim on it, since the beggining.
I didnt had the problem before the update. And for sure the problem poped up some days after the update.
When i see that msg the most of the times (if not always) data is enabled.
I should also say that when i see that msg the phone is just sitting untouched. Phone has never dropped or anything like that.
For sure its annoying.
When i restart phone sim is working perfectly...... ..
Has anyone heared about it? Anyone who faces the same prolem and found a solution?
I tried to google it ut i came up with no answers...
Any help is welcome.
Thank you in advance

have u tried a different SIM yet?

I had the same kind of issue on my previous phone. However, there is no data on my phone that I had to reboot my phone a few times to establish data connection. Secondly, sometime I missed called. Replacing SIM card may not help either. A few people had reported the same kind of issue on T-Mobile Support site.

I tthought I was the only one plagued by this issue..
I have this same issue. It usually happens whenever I lose network coverage......it happens repeatedly.. This issue started happening after I updated to jelly bean...ICS had no problems..
I have changed my sim 3 times, installed several touch wiz custom ROMs, changed my base bands and kernel...The issue remains prevalent after all these..
The only way I have been able to resolve this issue is by switching to an AOSP ROM like cm10 or paranoid android rom
I hope a fix for this issue is found soon cos i am tired of restarting my phone everytime i lose network coverage
I have attached a screenshot showing this

replacement sim ractified the problem

I had the same problem the other day when I was driving home from work. I think it happened when I went from 4G to 2G coverage. And also, when I'm in 2G coverage, signal fades out completely and comes back on 10 secs or so later. I went to Tmobile and replaced my sim with a new one and I had no problem of such ever since. .. at least so far so good.

Believe me I have Odin end back to stock n the issue still persists.....changing sim cards is only a temporary solution....
The problem always comes back especially if you always in an area with no network signal

Warranty exchange! Samsung should replace it. Say won't read sim card. Or tmobile

It seems that it happens when the data signal is bad.
Yesterday i had to reboot more than 3 times inside in a 4h period.
Wth........

First & foremost,
How did you "unlock" your phone? Did you mess with the NV data??
Or were you a good boy & had T-Mobile do it for you?
It sort of sounds like T-Mobile may have disabled your SIM card altogether....which may happen if you screwed around with the NV data.
If it was properly unlocked by T-Mobile you should be able to stick whatever SIM card in there now. Easy to test, go down the street to your nearest Greek mobile telecom store & ask if you can test a prepaid SIM card in your phone. Assuming the GSM networks are to some degree similar to the US T-Mobile networks, you should even be completely in good shape using local GSM service.
*IF* you get the same issues with the local SIM card....well screw it then. Go protest in the streets about the austerity measures in effect at the moment. Or just be a lazy Greek bastard & demand 14 months salary paid, require retirement at age 50 and lastly *NEVER* pay property tax on anything.

Well i have unlock the phone through internet. I had no issues for the past 2 months at all and yes i am using a local sim card from the beginning. The problem came up with the last upgrade!
Besides that i have a backup of the nv data but i am pretty sure that isnt the problem.

LOL? What is that? Everyone around the world is talking about the Greek people and have no clue of what it really happens. I work 12-14 hours per day including weekends.... i pay more than 600 Euros on taxes per month and i ll never get those money back since retirement is at 70 yo!!! Most of the people are like this. Foking politicians and goverments who have been stealing money for so many years. That was the problem and not the people!
I wish i knew why you mention all these!

sim card removed
I'm having the same issue with my s3
I tried to unlock it using this method
http://forum.xda-developers.com/showthread.php?t=2014982
I'm not sure if it worked, but perhaps messing with NV data screwed something up??
I upgraded to jelly bean 4.1.1
I tried cleaning the contacts on the sim
I replaced the sim at WIND
I even tried a factory reset
Nothing worked so far.
Has anyone figured out why it's doing this? Is it hardware related? software related?

In the same boat as you...I thought i was the only one..
on wind's sgh-t999v Galaxy SIII ... unlocked it like you did, and I'm getting a no sim card, restart required error, get it about every 8 hours or so..
i ported my number over too, but it says under "my phone number" in settings.. has a completely different number than what I'm currently using.. not sure if that has any effect..
tried restoring to factory settings too.. nothing seems to work...
if anyone has any info that would be much appreciated...

From the cold boot and after the error message goes away, does your phone has data connection?
I got the same error message on my previous phone. However, it would not establish the data connection.

mine doesn't do that, I have a data connection almost instantly where I have a signal
the error goes away after a reboot, but the error stalks you, and you never know when it's going to strike..
sometimes when it's in my pocket waiting for a call, while i'm driving with a headset on, at night while i'm asleep
for me, it isn't consistent, but it eventually happens..
I intend on taking it to the repair center for wind next week once I get back home (with the family for the holidays)

I don't think this issue has anything to do with if the NV data was messed with because my husband and I have the same phone purchased the same day 6 months ago. We both get the same error message and it's does not always happen at the same time so I am not sure it has anything to do with the network either. When it happens to him, he tells me it's happening but it does not happen to me. I googled the error because it is annoying. I will guess now that this issue has to do with the Gallaxy s3 and the update to the firmware. I can't wait for a better update.

Hi again
Since I know that there are a lot of people facing the same problem I thought it would be nice to give the solution on this kind of problem.
It seems that when you update via kies (of course on stock roms) something goes wrong. Recently I install the latest rom using odin and except that I found so many new things that I couldn't see before I also had no sim problem again.
So I am pretty sure that this kind of problem appears due to the kies updates. And from what I saw there where more.
If anyone else try the same please let me us know if it worked.
Good luck to u 2.
Btw yes I had that problem when the data signal was almost 0... Maybe 0.... Only then!

First of all I want to ensure you that has nothing to do with the way I unlocked the phone.
Second nv data is untouched.
3rd the problem came on after an update.
As I said after a clear fresh install without ba kups etc, starting from 0 the phone works great again and also there are options settings etc that I couldn't see before. Crazy but real. If anyone else do the same thing and make a fresh install with the latest rom he will agree with that.
So... As you said we make good parties and have nice womens... But how you will caption those moments those special (girls) moments without a nice camera (phone) ?
Have a good day hehe.

For those on the SGH-t999v version of the phone... the reason you are getting this "no sim error" is because of the firmware update to 4.1.1. I've sent my phone in for repairs and the best answer they could give to me was that there's an issue with the current jellybean.. not sure about the SGH-t999 standard versions though...
Unfortunately, I've had to revert back to ice cream ....and guess I have to wait till Lime Pie (OS 5) comes out...
The issue is not the NV data as I have used that method to unlock my phone as well.

Thank you for your replies. I'm relieved to know that it is not the nvdata menu that caused this problem.
I sent my phone in twice now and I've recieved it back for the second time today.
The first time resulted in further Sim card error messages. I'm keeping my fingers crossed in hopes that it does not appear again.
If op would be so kind to lead me to the right direction as to how to use Odin, I'd greatly appreciate it.

[FIXED] No GSM? I thought I unlocked it!

Hey everybody, I´ve been having more problems than anticipated with my Dinc2. Basically what happened was this:
I had a phone that I bought new, unlocked, and used on the GSM network this past summer while abroad. (Verizon). However, I had dropped it to the point where the audio jack ceased to work and thus had to take it back in November for a replacement under the Best Buy warranty.
Now, in November I jailbroke the phone again, and I still have the code that I used to do it. Or at least I think I did it successfully, because I never checked with a real SIM card. After (possibly) getting rid of the SIM lock, I rooted, got S-off and flashed the radio following the instructions here, which had been working great for the past few months in the US (CDMA). Now I´m running MIUI on Android 2.3.5 and the baseband version is 20.27W.30.0811U_1.09.01.0622 and a kernel of 2.6.35.14.
Now I´m abroad again, working in Spain for the next several months. My first issue occured when I arrived and tried to use an SD card. Guess what! It would appear there´s a sim card lock. It doesn´t recognize sim cards when they are inserted, nor does the unlock code I got back in November unlock the phone.
It gets better.
The phone doesn´t show an IMEI number, nor is there an IMEI number on the sticker on the back of the phone-just a Serial Number and an MEID. Also, since it was a replacement phone under warranty it was probably a refurb, and I don´t have any other packaging on which the IMEI could appear. As a result I have no friggin´ clue how to get the lock off and allow me to use the 3g network as before.
Should I try flashing the stock rom and radio, or just the stock RUU, and see if I can get the unlock code to work?
Or is it hopeless and in that case should I give up and buy a ****ty candy bar phone?
Thanks in advance!

I had a similar scenario while I went to NZ. I thought I unlocked my phone prior to leaving, but didn't. I called verizon tech support and got a new code, plugged into the settings and then I was able to insert the prepaid SIM I bought. Here is the non 1-800 number for you to call (I had to get my brother-in-law to call them and get a non 1800 number because it is not listed on their website): 1-908-559-4899.
Try that and hopefully they can get you a new code to use. Good luck.

I just talked to Tech support today and got an unlock code... it´s not working however. I´ve put in a card, and it doesn´t show up. When I go to the SIM Lock under Options>Security, it says the code I enter is incorrect. Also, the phone shows no signal. Could it be that I just flashed a bad radio that supported CDMA and not GSM? Or is it something with MIUI? I was pretty certain that both the radio and the ROM were fine for GSM networks...

I got that to work. Thank you! I later installed CM7 to try it out and surprisingly enough that didn´t work.
AOKP did for me-although they are both confirmed to be working with GSM? Anyway, I realized I never flashed gapps with the AOKP, so I tried to flash with the latest version (no coffee, late night) and ended up tweaking the install. Anyway, I re-flashed and I have to say that this setup (AOKP with Nova) is the slickest setup I´ve ever used! It´s been an intense couple days flashing ROM´s, reading about all the stuff that kept popping up, but then end result is so worth it!
Anyway, I´m off to go caress my telephone...oh yes.

Unlocked GSM Galaxy Nexus - No signal al all

Hello,
A bit about my Nexus: Bought it online, it's the Domoco version, unlocked, rooted and been using just fine with many custom ROMs.
So yesterday morning, I was talking on the phone with a friend without any problem. After hanging up for a few hours, when I was about to call someone else, I realized my phone didn't have any signal at all. And it has been like that until now, about 48 hours.
It happened so suddenly without any warning. The phone has never been dropped and everything else working just fine.
So here's what I have tried:
- Restart the phone (multiple times)
- Batter pull (multiple times)
- Factory reset the phone (multiple times)
- Wipe cache and dalvik cache in CWM (multiple times)
- Downloaded SetCPU and set the minimum to 700Mhz (instead of 350Mhz)
- Reflash the ROM and tried with other Custom ROMs (I tried Xenon, Xylon, PA, and Carbon ROMs)
- Reflash the Radio and tried with other Radios too (I tried UILH1, XXLH1, SC04DOMLE3 and some others ...)
- I also went to Tmobile and request a new sim card - same problem.
- I borrowed a sim card from another Tmobile customer to try it on my phone - no signal - but the sim card works just fine on his phone.
I ran out of thing to try and I dont understand what happened ... anyone has an idea or something else for me to try ?
Anyone experience this before ?

Welcome too my hell. I have a playstore one now but my first Gnex was an international one and it has this same issue. Its a PCB problem a warranty would fix. I'm near Chicago and a few people have told me there is an electrical engineer downtown that fixes stuff like this. I don't have a price but I think something like this is your only option. Mine sadly is still a battery charger:thumbdown:

I know it sounds stupid, but have you tried toggling airplane mode? I run into the occasional loss of signal when im at work [fair to weak signal in the big metal box], and a reboot is the only thing that fixes it for me. Mines a play store model.

Ah yes, I actually did try that too but forgot to mention. I tried toggle airplane mode on and off, also the 2G only mode on and off. But it didn't help with anything.
Thanks for the suggestion.

So I guess I have to look for an electrician then, cause I have this phone just a little bit over a year so warranty is a no go for me.
Thanks for the idea.
PS: anyone else has more option for me ? I just wondered if I have bricked my phone ... cause I flashed lots of diff. ROMs to try out but never gotten a bricked phone before, could this be a bricked phone ?

Bricked refers to a phone that does what a brick does: nothing. It doesn't boot, it does not light or attempt to boot, it does nothing. This is a signal issue..I have no prior experience with docomo, but this thread came up on search: http://forum.xda-developers.com/showthread.php?t=1574018, maybe it'd be helpful. Have you converted it to yakju or takju and tried a google factory image?
And this: http://forum.xda-developers.com/showthread.php?t=1554150. If it is a circuit board, it kinda looks like s.o.l., and im sad to say that to you.

I wanted to let you know that I experienced the same issue. I bought the unlocked Docomo Galaxy Nexus, and had it working fine on T-Mobile for half a year, and then suddenly had no signal on Tuesday. Nothing I did - factory reset, battery in and out, sim card in and out - could fix it. Have you tried using different sim cards in your phone to see what works and what doesn't?
I figured out that my phone will accept AT&T, and actually does connect to T-Mobile while roaming (I used an international sim card). But, my phone will say "Cannot find mobile network" when any T-Mobile sim card is inserted.

I also have the same problem with the docomo phone. ATT Sim card works. Tried other's T-mobile sim cards and it doesn't work. I wonder if somehow the IMEI has been blocked by T-mobile.

I know others who bought their GNEX through the Play Store and those work just fine with T-mobile. I tried their sim cards in my phone and it doesn't work. I don't think T-mobile is intentionally blocking the docomo phones, because I'm getting T-mobile through roaming, when I use an international sim. My guess is they're doing something to the cell network that just somehow leaves our configuration out. Hopefully it's temporary, but who knows.
Worse case, I'll just purchase a Nexus 4, because I love 4G data for just $30/month with T-mobile. Anyone else got suggestions?

I also have the same problem with the docomo phone. ATT Sim card works. Tried other's T-mobile sim cards and it doesn't work. I wonder if somehow the IMEI has been blocked by T-mobile.

Alright, update on this and there' good news. I called Tmobile and they said my IMEI is actually Blocked. The reason, according to him, is that Tmobile usually sweep the network to clean up all "un-supported" devices, so my device is apparently one of them and therefore got blocked about 2 days ago.
So he said for this, he needs to escalate it to business support and they surely can unblock it for me, but I have to wait until Monday since they don't work on weekend. But well, that's surely a good news. phewwwwwwwwwwwwww !!!
So to all of you guys who are in the same situation, make sure you call Tmobile first before flashing crazy like I did LOL.
Thanks for all the help.

I'd love to know if you are able to get this unblocked and working as I have the same problem as of Tuesday. I was traveling and went into a TMO store, and they told me it was NOT IMEI blocked. In fact they looked at the IMEI and read the page and said 'it was not eligible for blocking'.

I called TMO to see if my phone is IMEI blocked, and through three levels of support the universal answer was no. I'm now fully confused because if it's a hardware issue, why did several people all have the same problem all on Tuesday. For those others who are having issues, can you see the TMO network but not connect to it? That's what I have, I can see TMO and AT&T but haven't been able to connect to either one since Tuesday.

I'll call up T-Mobile tomorrow and ask if they IMEI blocked my device. I had them reset my signal and give me a new SIM card, but didn't realize it could have been IMEI blocked. I'll give them a call on Monday and let you know what the result is. Maybe it won't be too late to cancel my order on that Nexus 4...

I'm quite confused. I've been told last Thursday in a TMO store and with tech support that I didn't have an IMEI block, and the same with three reps tonight. I know the Sim Card is good, and so I'm being told its a hardware issue. However, several of the same phones had the same issue on the same day, so I can't buy it's a hardware issue. Has anyone with this issue flashed a new or different radio into the phone, either before or after the service loss? I have not, running it as it came out of the box.

I just got off the phone with T-Mobile Support, and they told me the device is not blocked. The reason is that T-Mobile cannot block or unblock devices that are not registered to T-Mobile. So I'm back to square one on this.

chowabbajack - When did you first have a problem, last Tuesday? Did you prior to that do any flashing or radio changes to the phone?
We're in the same spot....

I did not do any kind of flashing or radio changes prior to Tuesday, when I lost signal.

That makes me think its something to do with the radio software, because I am the same the problem overall doesn't seem as large as the number of phones I perceive were bought on the Docomo deal.

Ive been using the docomo version of the nexus as well on tmobile for almost a year and it was since last tuesday when it no longer recieved any singal. with some digging around and too many phone calls, I found that the imei number on the phone is not the same as the one under the battery. i have the generic 004999010640000 imei right now and it not sure how i got it. as i bought it unlocked.
what i have tried:
reboot, battery plug, reinsert sim, factory reset, root and flash, got a new sim card, relocked, unlocked
sim card works on other phones.
also i have called tmobile and samsung endlessly and this is what i got:
tmobile cannot unblock the imei since it is not from them.
samsung is redirecting me to their japan branch.
docomo i cannot reach.
my phone before last tuesday:
unrooted stock 4.2.1
been testing different things to see if there is any way to restore the imei
also using root explorer, i cannot find my efs folder....

I've got the same problem since last Tuesday with my GNex and T-Mobile.
Mine is not from docomo though, but the French phone provider SFR, unlocked through FDocomo apk.
Rooted phone, running 4.2.1., no changes whatsoever in the past month and it worked fine until Tuesday, so I don't think I'm responsible for having no signal.
Honestly, I am relieved to see we are quite a few to have this problem, and also very pissed at T-Mobile for causing all this. What should be the next step then? Is there any chances they fix the issue quickly? If not, I might just go to the competition. I've tried AT&T sim cards and they work fine.

I have the exact same generic IMEI number as you, which does not match the number under the battery. I'm not liking the news that you did flash and still no go. I'm a novice at this stuff so please keep us posted.

SIM card not detected - then detected again

My phone is constantly failing to detect the sim card, usually if I restart the phone or leave it for enough hours it will "find" it again.
Short of reflashing it I'm not sure if there's any way to determine if this is a software or hardware issue. The phone itself is a refurbished one (thanks to the phones insurance replacing it a few months ago), however it is now out of warranty. If it was a hardware fault, how much would it probably cost?
Thanks, Shaun.

The first thing I'd try is a different SIM card or a different SIM card insert (bit of plastic that the SIM sits in).
Has this always happened since you've had the phone?
or
Has it happened since you flashed the phone?
As for the price of repair I haven't a clue (i do all repairs myself), but my guess is in excess of £150
You may want to provide more information before other, more experienced people, come to your aid.

It's slowly gotten worse over the last few months (the first couple of times I just thought it was a once off bug or something, which is why it's very difficult for me to give you an exact when it happened).
The fact that its gotten worse in itself is leading me to guess its a hardware fault - I could have knocked or dropped it and not remember or something.
I don't have any other SIMs but I'll give flashing it to a different ROM or stock a shot first.

I feel as if that is your best best before you go throwing money at it.
Good luck!

Does the phone say no sim card (with icon) or do you lose service?

It has done both, the latter's slightly more common though. Probably more often than both it will momentarily drop out, then come up with a "Preparing SIM card..." message.
Still happening after flashing it with a different ROM. Looks like it's probably hardware :/

Might be coxicial cable that connects the pcb with antenea board they do come off from time to time

Hi there,
i have a similar problem with my device:
network disconnects sometimes (for some reasons ok, as example when i sit in the underground or other places without gsm network) - but then the services doesnt comes back - i'm complete offline. next behavior: i'm just talking with full gsm bandwidth, and for really no reason i get disconnected -> no network anymore, no service anymore.
can it be a hardware fault or should i try to flash the modem (when possible) ? I'm on the latest HTC firmware, device isnt rooted or flashed... it is as i got it from the market.
thanks for a hint what i can try

See above could be that, what network you on?

I'm on GSM (in Germany the O2 network)

maybe the network fault can be solved:
just have read in the vodafone forum in uk and found a hint from a user, who was taping the back side of the SIM card with 2 stripes of plastic.
Have tried this and report tomorrow here if it solves the issue

Tested with taped SIM card and i can say: it works like a charme
