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.

he might still be able to re flash the baseband via this method, especially if he still has the old one http://forum.xda-developers.com/showthread.php?t=1180331

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. I flashed to CM7.0.1.0 stable and bam I have an Invalid sim card, I have tried to unroot, stock flash, NVFlash to stock, trying a different rom altogether with no avail. I have tried NV BAT Flash with NVFLash and nothing. I have found many post about CM7 after of course I flashed mine. My previous sim was new in April of this year, but I went to T-Mo and get a new one today with nothing. I to have wiped, licked, and spanked my phone with no results... CAN ANYONE HELP?? Can't even send it back in because I cant unroot it... HELP!!!!!

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.
Okay, I'm basically going to just copy and paste my issue and edits here from the Zeus thread I couldn't get any help on. The edits are so anyone who actually read this can see what I did and have been doing so they don't suggest something I already did.
So the other day, I tried to flash to the Doctorz ROM and of course, made a Nandroid backup. After messing with Doctorz, I went back to Nandroid or clockwork recovery (whatever it is) and after restoring, I was on another modem and stock kernel. I tried to reflash Zeus and wiped partitions cache and dalvik cache and now I'm having serious issues. I have my SIM card in my phone, but it keeps telling me I don't even though it's there. Even weirder, I have one or two bars even after I pull out the SIM card. Earlier, it was detecting that I had a SIM card, but said "Invalid SIM card" or something and now whether it's there or not, my phone says it has one or two bars even though I can't do anything. What's going on??
I've tried rebooting several times and activated Wifi and airplane mode, but had no luck. SIM card's in right now, but my phone says no service.
EDIT: Forget it. I just did a factory restore and wiped everything and reflashed Zeus.
EDIT 2: Okay now I'm having other issues. My phone recognizes my SIM card again and now I'm getting my normal signal, but I can't do anything wirelessly, like send a text or use up data. It SAYS I have signal and am connected to the HSPA+ network and the arrows are flashing and whatnot, but I can't do anything wireless. I can't go into the market, send a text or use the internet browser. Someone please help?
EDIT 3: Okay, I was wrong on that last part. My texts weren't going through because of bad signal, but I definitely have no data AT ALL. All I have are a few bars, but nothing about 3g/EDGE/HSPA+. I think this is an issue with APN settings?
EDIT 4: Messed with some APN settings... kinda back to square one, where the H+ shows up and I get Edge sometimes (I have bad signal where I'm at) and the arrows are flashing, but NOTHING. I still can't use the market or any data at all.
EDIT 5: I just decided I'd try to be next to my router and turned on Wifi... my phone would not pick up a signal from my router at all, and it works just fine. I'm starting to think this is a modem-related issue...
EDIT 6: Okay, I kinda fixed the problem, but my data speeds are SUPER SLOW and sending one message takes a really long time. I know I have bad signal, but it's never been this slow, even when I manage to pull up two or three bars. I tried messing with build.prop, but as I'm on Zeus, the settings were already fixed up.
EDIT 7: Okay, the Wifi issue was because I used the wrong WEP key. Oops. After I managed to connect though, I couldn't get any data. My phone just doesn't want to use up any data apparently? I reflashed the modem Zeus normally uses and now if I manage to get some data, it's unbelievably slow and can't use Wifi data.
EDIT 8: I forgot to mention that if I don't get to connect somewhere with data, my phone will just tell me there's no data connection or whatever even though I have two bars. I tried to fix permissions and rebooted, but no luck.
Someone please help. This is really annoying.

Damn! That's a lot of edits. Odin back to stock, and start from scratch. But remember to do a factory reset from Phone, go to settings, Privacy and erase everything. that will clean up everything that you have there.
That's the only option I see will fix all your problems

Yeah, that's all I could come up with. Thanks anyway. I did that a few minutes ago and flashed Zeus. I'm just waiting for my phone to load up. I tried to let it load up, but it kept saying not enough data on the partition or something. I probably shouldn't have tried to flash Zeus immediately after flashing back to stock. After I went to CWM from flashing to stock, I immediately tried to flash to Zeus, but had issues. I'll take the blame for trying to rush and take shortcuts. I'll see how this goes again though.
Okay, after flashing back to stock with Odin, my phone loads up and does the "Rethink possible" thing when you turn it on and after that, nothing happens. The screen just stays off. If I press the power button, nothing happens, but if I hold it, it just reboots and goes back off. This is just annoying...
EDIT: Okay, it worked the second time. I have no idea why as I did nothing different, but it works. Now I'm gonna try to flash Zeus again.

Faint,
I got lost trying to understand what you were trying to ask.
Gtg unbrick is prob the best option.
It's usually best to describe the system, setup, the bug and the attempt.
Then pose the bottom line question.
Check my last sigs link.

Well what I was asking originally was how I can fix the problem I was having, but flashing back to stock via Odin helped. Now I'm having ANOTHER issue... after FINALLY having fixed up everything, I tried to restore some stuff with Tibu, but then my phone started saying a bunch of processes were force closing or something, so I tried to reboot and now I think I'm bootlooping. I'm stuck at the "The Collective" thing that shows up when you boot up your phone and it doesn't do anything. It'll go and do what it normaly does, go black and start up again, then come to a complete stop and repeat the process. I then went to CWM and tried to wipe factory settings, cache and dalvik cache, but I'm still having this issue. Geez, it's one problem after another, and all I wanted to do was restore my apps. On the bright side, I DO KNOW flashing from Odin helped because once I regained control of my phone at the way it should be normally, I had my normal data speeds and didn't have issues with data. I'm going to try to fix this bootlooping issue now. :|
EDIT: Escaped the bootloop(?). Thank God... I honestly thought I'd have to flash back to stock with ODIN AGAIN and then redo everything.
Hey, so another question... before I flashed to stock and everything, I backed up all of my apps with TiBU, but now I can't find them; the restore file(s?) so I can get all of my apps and their data back. Was it saved to the internal SD card? Because I formatted that after backing up...
EDIT: Never mind. I looked around my SD card and... ugh. All my apps are gone and so are my backup files for the apps. Great. Thanks anyway, you two.

If you did a factory reset from within the phone, it will erase everything...
After you odin or heimdall a stock package, and flash a new ROM, don't restore tibu or apps. Download new.
Occasionally they get corrupted and cause you phone to soft boot

One more thing to add on to the TiBu thing, when you restored your apps what option did you use? If your restoring the batch options only select "missing apps with data.". Any other option and you run the risk of getting constant FC's.

I have found this to be the best for me also, new ROM...fresh install of all apps...so easy when you have the apk's, I just put them in a folder, then to my sd and install away and if I need to update I look that app via the market and update that way, or via the desktop pc thru the market online.
I found this site very useful has all my apps I need/require:

Yeah, it seems that's the best way to go. Even though I backed it up with CWM, I didn't expect it to not backup the kernel and modem. I realized the kernel part a lot sooner, but after having a lot of texts that didn't go through the way they normally would, I thought it was an issue with my phone and then I decided I'd check the modem and found out I didn't have the KL2 modem I'd normally have.

Well I already had everything figured out by the time everyone said something, but I appreciate the effort and tips nonetheless.
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.

And a thirty second search get this:

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.
Just in case this post gets moved, I want to identify my device as the Verizon Samsung Galaxy S3 (i535).
To give a little background on my issue, I have an issue with the device. When I first got it back in July, first thing I did was root the device. Naturally, since it was a new device, I was working with experimental methods... a couple weeks ago I thought to download CyanogenMod 10.1 (nightly build) to flash it with 4.2 and rid myself of the persistent OTA update that as we all know could not effectively install because of the measures I took to root. So, I boot into recovery and flash my custom rom. BAM! As it turns out, I did not have an unlocked bootloader and my phone was now teetering on the verge of being a $600 paperweight. I got that dumb yellow triangle saying unofficial firmware detected or some nonsense like that... Anyway, I look around the internet and decided that I was going to revert back to a stock rom using Odin, and then proceed to unlock my bootloader and root the device (I followed method 3 here) I used some touch recovery console that I have never heard of before (backups incompatible with ClockworkMod recovery) and something must have failed because my back up would not flash. I took the hit on losing most everything and reflashed successfully the custom rom mentioned earlier.
After about a week, I noticed the device began to drop data. 4G would just stop at random parts of the day, and I would have to disable and enable the data to get it to reconnect. At this point I was still able to make and receive phone calls and texts. After about 3 days of this, I concluded it was more than likely a bug in the custom rom, and that I could not live with it... so I redid the a fore mentioned tutorial and left the phone as a stock/unlocked/rooted device. The data issue continued, but with a twist. I was now unable to make or receive phone calls or texts. No matter what I did, I could not do anything and the 4G would only stay connected for a matter 5 minutes or so. When I logged into my vzw account, it identified my device as an unknown non-verizon device. Customer service walked me through various soft/hard reset techniques and nothing worked. They also suggested I try a new SIM card, which failed to work.
So, I turn to the bright minds of the android community. I have already decided not to invoke the Verizon warranty offered, where the result is they take my malfunctioning phone in flawless cosmetic condition and replace it with a "like-new" phone in working condition, because I think it's garbage that a warranty would give out used crap (should fix or replace). I have not contacted Samsung customer support yet because I wanted to see what my options were. I've already attempted flashing different radios and nothing seem to make any difference. If I have to, I will revert it back to stock again and invoke Samsung's warranty program, but I would much rather keep the phone. As it sits, I am stuck with my Motorola Droid Razr Maxx, and that just doesn't cut it.
So I ask, is there anything that can be done? Anyone know of a fix for my situation? I saw something about this in my quest for an answer and I don't know if my situation is a fit for this fix. If anyone has any knowledge of my issue and a work around for it, it would be greatly appreciated. I am at my whits end.
It sounds like you've done your homework on your problem.. The only thing in your post I didn't see was your sim card.. Maybe pulling it wait 2min restart. Shut down and insert,, or maybe a reprovision of the sim may be in order..
Ahaaaa....!!!
If your IMEI is intact, I would say to flash to ICS and reprovision the phone as suggested above. If it is not, you need to restore it with that backup that you made some time ago.
If it were me, I would reprovision, that is easy to do and I honestly think that it will work for you. If that works for you, reroot and restore your backup for TW ROM and you will be fine.

Well that's just it... I don't know anything about the IMEI and how to determine if that is the issue. If by reprovision you mean reflash back to stock, that is it's current state, and that did not resolve the issue.
As for the other comment in regards to the SIM card... I have already attempted that method, and it did not work. Also, a new SIM card was also tried, and had no success.

Google reprovision, it is a number combination that you enter on the keypad that resets your phone. I had a similar problem that you are having and that fixed our for me. You also need to know that when you do this, it will erase all of your information on the phone. It will be just like it was when you unpacked it and powered it on the first time.
You will have to be on ICS because they removed the option to do this with JB. Just search for the code to enter and you will be fine.

Ok. So I tried the reprovsioning mentioned above. When my phone rebooted I was on data and able to make phone calls. Score! However, I checked the IMEI and it said 0. So, thinking that it was just a matter of time before my device began to stop working again... I did the IMEI fix. Now my phone is placing calls and holding data without issue. The OTA updates are flooding in and installing without issues.
I would like to point out, while I feel better having done the combination of both reprovisioning and IMEI fix, ultimately the initial reprovisioning did appear to resolve the issue.
Thanks to everyone for the assistance provided.
>> Partial solution was found; still looking for the root of the problem. <<
I recently decided to take the plunge and root my OnePlus One and install sultanXDA's CM 13 ROM on it. It was all going well until I booted up into the ROM and discovered that I couldn't get any mobile data. Everything else was working, calling, texting, wifi, but mobile data seemed to refuse to work. Since I initially flashed sultan's ROM with TWRP 3.0.0, I suspected it was a problem with my modem. Though unable to install TWRP 2.8.6.0 to re-flash everything, I did still flash a new modem via ADB. This didn't help.
I have tried many things to fix this. I rebooted/reflashed. I flashed different ROMs. I tried flashing on TWRP 2.8.6.1, though I believe that one has the same modem problem as the versions after it. As mentioned above I tried flashing a modem over ADB. I took out and re inserted my SIM card. In the end, I tried this guide here to restore my phone to it's original state. The guide flashes the stock versions of everything via ADB. Though it did return me to unrooted COS 12.1, it was not able to resolve my data problem.
After the total reset, all I can think that could be causing it is a hardware problem or that it is caused by something not reset in the 100% restore above.
If any of y'all can help my solve this, or at least offer insight, I would be very grateful.
Preemptive Edit I Guess: This thread was just suggested to me while writing this. I'm going to try the solution here and report back. It's OnePlus' reset to stock method. I'm not expecting much after my first 100% reset attempt, but we'll see.
EDIT: Ok, so the solution above fixed my problem... (edit again: turned out to only be a partial solution. See below.)
I would feel really dumb right now if it weren't for the fact that I slaved over this problem for a good ~8 hours before writing this post. Anyways, I'm not sure how to delete this post or mark it as solved. Sorry for the trouble y'all.
Never delete this post !!
I have the same problem, and I spent much more time to find a solution.
I will try this and will update.
Is it a clean stock rom?
Edit:
Didn't help for me ..
Still the same problem, No mobile internet connection.
Thx anyway.
Yeah, actually I was too hasty is identifying this as the solution. For me, the stock reset brought me back to CM 11 which didn't have a problem with mobile data. But if I try to flash a later ROM or update via OTA, the problem returns. I'm still trying to figure out what is causing it. The only information I can find points to it being a modem problem or APN problem, but I'm sure I have sufficiently checked both of those already.
Either way, I'll keep looking. If I find something I'll return here with it. Good luck

I gave this a try, but booting up after step 3 I still had the same problem. If I understand this method correctly, I think it is essentially the same as the other full restore methods I tried.
I think I may have found the problem though. I was looking at OnePlus' guide to installing OxygenOS. In it they said, "do not try to flash this build through TWRP. You will most likely lose your radio and IMEI which means a trip to our customer support." At this point I have repeatedly reset/restored my modem/radio so I don't think that is the problem, but I haven't seen anything about IMEI before. The IMEI is apparently stored in the EFS partition which as far as I can tell, is not touched by any of the restore methods I have tried. I took a look at my IMEI (about phone -> status) and it turns out my IMEI SV is 00. It's supposed to be a 16 digit number. I found a guide to fixing it, but I think I will just contact OnePlus customer support first.
I'll be back later with my results.

Are you flashing each of the extracted .img files from fastboot, exactly like the guide shows, or are you doing something else?

Yep, I ran each command listed in the guide and my phone was definitely in fastboot. Each command had a collections of "OKAY"s and ended with a "finished", which I assume means it executed as expected.
I have tried 2 different sim cards in my OPO (of two different companies, one of them as mine), and mobile data worked perfectly. Is it possible that my phone is ok and the problem happened in the sim card?
AND... my IMEI SV is 00 too. please update here if it has a connection.
Thank you !

I'm not entirely sure what you're saying. Did it not work with the first SIM card, but it worked with the second?
Mobile data problem was occured (to me), after I rooted my OPO and tried to flash a new rom.
I still can't understand how it convinced my sim card, but the fact is that I tried two (to be sure) other sim cards which are not mine, and mobile data worked well.
When I returned my original sim card, problem started again.
So I am almost sure that sim card has a connection, but can't understand why. And why it happend precisely now, cause it worked well over two years.

Why don't you flash twrp flashable modem?
If your network is present but no data , mostly data service problem. Are you pay your mobile bills ?
Are you activate data services ?

...yes i paid my bills ..
- my network connection to provider is dead...it worked perfecly for 1 month out of the box (see original posting for detailed action i took) this thread is about lack of data connection...but also MODEM related???
- tried the brand new simcard in my old Samsung sII... works perfetly, network connection with provider, data connection and calling..so no simcard problem
Long shot. Change any APN settings from IPv6 to IPv4. That was my problem when I had text/voice but no data.
I made a post on this and then called att gophone, due to seeing other sims working on this thread, and he helped me to fix. Posting my fix here in case others with isue find this post instead of mine.
Turned off wifi.
Turned off cellular data.
Went to APN and changed the apn (ATT Go Phone) from pta to nxtgenphone.
Turned on cellular data.
Finally had H+ above he signal bar, but had an X inside the bar.
Don't know if he did anything on his end, but the X went away after a couple of minutes.
Data was working, albeit kinda slow.
Turned off phone for three minutes per ATT rep.
Rebooted.
Data still slow, but it is at least working. Thinking I need to flash different modem. Battery usage has been higher the last day or two since I flashed c7 anyways.
