Hey Guys,
I need some help with my G2x. Everything was working absolutely fine with it. I updated, modified the phone etc everything working great. One night, I'm sitting here and I pick up my phone to use it. I notice it says invalid sim card and I have no signal. I figured either T-Mobile had a problem or maybe I just needed to hard reboot. I did that, nothing. It finds the network for t-mobile, but it can not connect. No matter what I do, INVALID SIM CARD. I restore it, INVALID SIM CARD, NVFLASH restore to factory, INVALID SIM CARD. It was working completely fine and then one night it just crapped out and it's been over a month. I can't figure out what to do. I went to a t-mobile dealer today and got a new SIM card, it says the same thing! INVALID SIM INVALID SIM INVALID SIM.
I don't really know what to do at this point, I've tried everything.
I searched all over the forum, heard suggestions from call t-mobile to restore etc but nothing is working here.
My last ditch effort is to try unlocking the phone. I'm waiting for the unlock code now, but I'm really hoping that someone with more experience might know what I'm dealing with here and hopefully lend a helping hand in terms of some advice.
It'd be greatly appreciated. I'm fairly saavy when it comes to recovering bricked phones, etc. but I've never had an APN issue where the APN is good to go and the SIM works in other phones, etc. but not mine including when a t-mobile dealer actually links a brand new sim to the phone and it still isn't working, etc. No clue what's going on but I'm hoping unlocking the phone will help. Any help would be really appreciated.
Sorry to hear that happened. Did u try a different sim?

yes no sim card is currently working on it.
I just unlocked the phone, it does not fix the problem.
It continues to say invalid sim card. :-(

In the settings menu when I go to APN's it has the t-mobile apn and everything is correct. I go to network operators and ATT, T-MOBILE US and T-MOBILE GSM come up, but when I try to connect to any one of the three it says "unable to connect to this network at this time. Please try again later" I am mystified. I've tried everything I can think of.

Another point to make.
When I put in the sim card, even though it's NOT registering to the network and every card says INVALID SIM CARD, I received a notification telling me that I had a voicemail......... when I put my sim card into another phone and called my vm, I did indeed have a v/m.... so I don't believe the phone is shot, I believe something is just very wrong and I don't understand what it is.
You need a new similar, this happened to me, I rooted my g2x and it said invalid similar, if u show T-Mobile they will give u a free one

Go to T-mobile or call get a new Sim card stay until it works are do a phone exchange but stay until they fix the problem your phones is still under factory warranty of they can't fix the problem they violate the contract

have you tried a full wipe then flashing a new rom?
simple method to try
Multiple times.
I've NVFlash recovered to stock.
I've flashed multiple different roms.
I'm wiped everything over and over, hard rebooted many times over.
Completely formatted the phone and recovered, etc.
I've tried a million things.
When I put the card in, T-mobile comes up for a second then goes away and says invalid sim card. I went to a t-mobile dealer, they gave me another sim card and it's the same thing. I really just don't know what to do. I feel like I've tried everything.
Do you have another T-Mobile phone, or any unlocked GSM phone, you can use to test the sim card? At least that way you can determine if the problem is with your phone or the actual sim card.
Sounds like an issue with your phone, but its always good to be sure.

if thats the case, then whats your warranty status?
they can replace the phone for you if the SIM card slot is defective
Unroot make , update to 2.3 if u haven't already and re root

Sounds like your baseband code got corrupted or your baseband chip went bad. Restore it and do a warranty swap if you can. No way to reflash baseband at this time on the G2X.

Yes, if that works it will flash the new baseband and return his phone to GB stock. Worth a try.
hey guys... no warranty. It's fix it or I'm screwed, unfortunately.
It sounds like you guys identified the problem with the baseband corruption..
I'm going to try and do all methods suggested in the thread including unrooting and updating to gingerbread, rerooting... and also flashing the baseband...
I'll be back with some results!
Thanks for all of the suggestions, I'm obviously hoping I can resolve this!
Thanks again
I got "invalid sim" only when trying to start wifi calling and booting to CWM and wiping the cache and rebooting solved the problem.
If nothing works for you get a new sim card from t-mobile.
T-Mobile also had some funny setting in my account and after several hours with tech support and providing a sim card (phone number) of friend of mine they fixed it. As in ..my phone worked fine with my friends sim card but not with mine.
[HELP] I am having the same issue. I have a T-Mobile G2x/P999. I have had at least 10 roms without issues on the device.

Yikes! Thats taking phone sex to a whole new level ... Did you try removing the battery and sim card, waiting a few seconds and then reinserting and rebooting?
Sent from my LG-P999 using XDA App
Yes I have done everything possible... Before the CM7.0.1.0 rom was installed, my baseband was from March 2001, now it reads July 2011. I have tried to switch back to the prevoius Baseband, but it wont let me either.
so i had an issue i resolved where my phone was stuck on hboot but i was able to get into recovery and flash cm7 nightly and now my phone boots but it doesnt recognize my tmobile sim card and i cant access a network. i used the ace hack kit to remove carrier lock. i also tried installing other roms and they all dont recognize the sim card. help please!

Make sure that the back door (SD card and sim) is ok. Many times when the back door is pulled the phone won't recognize the sim card.
it seems intact, the sd card slot works fine. and my sim card works on my other tmobile phone. also another issue, my device is always running on safemode, i have tried installing other roms and also reverted back to stock but it is constantly running on safe mode. is there a way i could revert back to complete factory origninal settings and start a new clean root process?

Hi Guys,
I just bought an infuse last night off from craigslist. I checked the phone thoroughly before I bought it and everything is working fine. When I get back home, the phone signal keeps dropping on and off so I thought the sim card might be loose. So I took it out and reinsert the sim card. Boot back up and the phone won't recognized the sim anymore. Keep seeing please insert sim even though the sim card is in there and worked fine earlier. I reset it to factory default but no luck. I put the sim in different phone and it's working fine. I tried with different sim card from my friend's phone who has galaxy s 2. The phone detected the sim but no signal at all. I reboot, factory reset but no luck at all.
The phone has CM7 rom and when it was working, it was great. Is there any way I can fix it? I checked the phone on samsung warranty info and it's only 3 months old, so still under warranty. I don't know they will honor warranty though since I bought it off from craigslist. Is there anyway I can fix it? Please help me. Thanks a lot.
Reset to stock and see if that helps. Try using some other working sim and check if the problem persists.
I have already factory reset it. Tried with 2 different sims. One sim recognize but no signal. Should I flash back to stock rom and try?

I would flash back to stock via Odin or heimdall and see if the problem is resolved....

I just flashed back to stock with heimdall. I will test out and report back. Thanks.
edit. Doesn't work even after flashing back to stock rom. Sending it out to Samsung for warranty repair. Thanks.
So I'm totally at a loss of where to go or what to even search for.
I have a verizon Galaxy s3 that I rooted and unlocked the bootloader on. I flashed a couple ROMs and now it won't connect to the network. It tells me it is in roaming mode only. I called verizon, but they said to just return the phone because it won't talk to their network.
I've read some things about "triangle away" and I kind of tried that. But it kept telling me that my flash count was 0 anyway. So it didn't do anything.
My IMEI and ICCID are correct to my sim card and phone. I originally flashed CM10 for the verizon s3 and it worked great for a few weeks. Then I tried a couple others and they worked also. Then I flashed the euroskank ROM, and that's when it no longer would connect. I went back to a previous nandroid, and still no connecting.
I don't know what the problem is, or what to search for, or where to go.
Should I try to install a stock rom. I know I keep seeing things about odin and installing the stock rom. Should I do that? That's something I haven't tried yet.
So, I tried reprovisioning the phone with *2767*3855#
And when I did that, it said sorry, your phone is not yet activated.
But I know it is, or, at least was activated. And when I call verizon they tell me it has been activated already. I don't know what to do. I'm thinking of trying to go back to stock
Same Problem
Flashed CM10.1 nightly just to test it out and then boom, no more connection. On any ROM. Scariest part? I have gone through the restore process and am now back to an unrooted phone with out of the box firmware. I believe I will take it back to Verizon now and see if they will give me a new one.

So I don't know if we have the same issue or not. But I got mine working for now. Don't know if I'll run into problems later, but this is how I got it working right now.
First, I installed back to stock settings and radio. I followed the instructions in this post
http://forum.xda-developers.com/showthread.php?t=1762709
I did the stuff in section 5. Including Flashing a Stock Radio. So I went back to the VRALG1 4.0.4 ROM.
And I did the I535VRLHE radio.
But it still didn't work. BUT, once in stock settings, I did the reprovisioning.
*2767*3855#
And then that finally worked, it went through, and my phone activated. So it works now. Hooray!
But I REALLY really want to know what happened. So I can avoid this happening again in the future. Can anyone tell me what happened, and why this fixed it? And how to prevent it happening again as a flash more ROMs in the future?
Also, SpecePatriot, let me know if that works for you. It'd be good to have more than one source to know that works.

Well that's good to know that you got it back working again. Sounds like it might be just be the ROM and not anything weird that we did to cause the loss of connectivity.

I had the an issue with my phone stuck roaming and this method worked great! Only problem I came across was trying to run Samsungs update for Jelly Bean, Every time I attempted to update my phone would crash and go back to ICS. Luckily I had a back up so I wiped my phone, restored from my previous backup (which had Jelly Bean) and worked without roaming issues!
My input is if your having roaming issues is to use a backup you made before you had the roaming issue. Follow this tutorial above to get your phone back to stock, root your phone, then restore from your backup through CWM or whatever you are using.
I am not too sure what causes the roaming issue but I did notice while looking for networks, my phone found ATT ad TMobile haha.I am assuming what happened was that the Cyanogenmod update I was downloading automatically was set for another carry which changed my wireless settings. I will be downloading nightly's manually for now on lol
Thanks for this fix, Saved me a lot of time and aggression

My S3 is having the same issue after a CM10 modification. Reflashing to a stock ROM fails, wiping and reflashing fails, trying a different rom on cwm fails, no backups to flash to (all result in error). So I stumbled upon this thread, read about reprovisioning, and I took it to mean input the numeric code into the phone dialer. I did that, and nothing happened. Can anyone provide insight on reprovision and how to do it? Google search on reprovision isn't giving me any hints.
If the reprovision is just failing and I've been doing it right, does anyone have any other suggestions? Really hoping my phone isn't soft-bricked with no ability to call/text.

Hey guys, when you provision does it wipe the entire phone, including the SD card? (internal SD card and external SD card)
stuck...
I tried all the above, stock, radios, kernels, codes, ##RTN#, none of it works, my radio works cause i tried 911 and it jumped on roaming and began to make call at which point of course i hung up before letting it connect any words of wisdom... at this point just a tablet for wifi

I have a galaxy note 2 on Verizon. This used to happen to me on CM 10.1 first stages but issue got fixed as the nightlies started. It only happened to me when I sometimes rebooted the phone or when the battery completely drained from 100-0% then when I would charge it and boot the phone it would show me an x and no signal bars. I would have to restore to a TW rom to get it to activate again but going into settings and switching to CDMA/LTE mode. Now I'm on ParanoidAndroid 2.99beta ROM and it still gives me that issue. Hopefully soon it will be fixed.:fingers-crossed:

Thank you buddy,
This helped me get my phone back in working order -- For those of you wondering why the "*2767*3855# is not working is because you are using the wrong flash. You must use "Official VRALG1 4.0.4" - and currently the link is down on the thread - I just googled it and found it elsewhere. I tried one of the other OTA's and it would not work. Also, do exactly as netskull described - even regarding the antenna. When using VRALG1 4.04 - The second i entered the last "hashtag (#)" it popped up another screen which helped get my phone working. I did not have to press send or anything. Kind of sucks that I lost all data on my internal card, but I DID back it up and now I will have to go through and restore. Since some people were wondering -- It did not mess with anything on the external card... It did unroot my device, however, so I will have to do that again as well.
For some reason, flashing the latest MIUI messed up my phone and put it in roaming all the time. Oh well, happy i got it working, and subscribed . Thanks once again Nertskull.
I did some research and didn't find a problem similar to mine.
I have a Samsung Galaxy SII Skyrocket that's 1 year, 1 week old today (so out of the warranty period).
I rooted it, have nova launcher, cwrm, and am running stock ICS on AT&T.
Earlier today, I noticed that I no longer had service which then went to No sim card inserted. I thought maybe it had gotten dislodged but that was not the case. I tried a factory reset and then a restore using crrm to a earlier date and still the same error. Even after the factory reset it had no sim card as the error.
My next step was okay my sim card is corrupt or something. Went to the AT&T store and got a brand new one and it still had the same error. this led me to believe it might be a hardware problem. I think I ruled out the kernel and the modem not communicating correctly because i'm not running any roms (nor have I ever on this phone) as well as tried to factory wipe and tried to put a fresh ICS stock via kies.
Any ideas as to why my phone still says no sim card? the sim card works as i'm using my old LGcu920 at the time of writing this with no problems. thanks in advance for any help.
flash my efs fix and then use Odin to restore GB. Reboot twice and then use Odin to flash ICS.

Before you flash that you might wanna try this. Take out your battery. Wait five minutes. Hold the power key(with the battery out) for 20 or 30 seconds. Then reboot. I've never seen anyone try this on the Rocket but I have seen it work on other phones.
