Data speed icon?? Gone?? Invalid Sim sometimes??

Okay I have been having the t-mobile "invalid sim card" issue and the phone currently is running with the t-mobile carrier logo. I was able to make calls, and connect via WiFi. I am not able to access the web2go page when I select data in the "wireless & network settings" page with a check. I used to be able to at least access this page with wifi turned off and it would show a little 4g icon on the top? I will post some screenshots. I downloaded GeRIL just to see what it said? I think my phone is rooted? I ran superuser and said the phone was not but the last action I did before getting the t-mobile to show up was a zip restore with CWM so I assume it's rooted? Might be just a flash? One other thing is that I have the WiFi and GPS on and it does not appear to get my location for weather in the weather app?? I can open Google maps and GPS is within 60 meters of my location. I want to reboot the phone but am afraid it won't be back to normal and I will get the error "Invalid Sim Card" again? Is there anything or tests to run while the phone is on the t-mobile network I should check first before rebooting? Or files I should try to use or flash? Or any service menu codes to run diagnostics? Thanks in advance. I forgot to mention that I will be getting a replacement from t-mobile in a week, I did the online chat and they said they will send a replacement under warranty. The box has a date of 7/29/2011 so the phone is about 3-4 months old? The phone is unlocked and has been rooted before, but the issue happened days before I modded this G2x. Basically, today it could connect and tomorrow it might not...or If I reboot It usually goes to the "Invalid Sim Card" I have read other posts with issues of the same type from other users but found no solutions?? Baseband, RIL, Sim ect...all points to a bad phone(using t-mobile) because If I use any other carrier card in the phone it works without errors. That makes me think it's a firmware with t-mobile issue but I could be wrong? Hopefully if the replacement goes thru the same ICS 4.0 will be out and make this phone a beast again?

This might work or it might not: rename your APN manually (Settings/Wireless/Mobile networks/Access Point Names/edit) you can either edit or restore to default to restore mobile data connectivity. Try restoring to default.

I just accidentally hit Airplane mode and it killed it!!! Now it's back to the Invalid Sim Card error again...bummer!!!!

Wait a minute...I waited and read a few posts and clicked the Airplane mode off and on again and it came back to the t-mobile carrier..??? I still have not rebooted the phone though? Hmmm...should I?

Did you get a new sim card when you got the phone? I remember when I got this phone they told me not to use my 5 year old sim card from my previous phone. I say try a new sim card, if that doesn't work try to reset the apn with the instructions I posted last, and if that doesn't work it might just be a bad sim card reader.

I think more on the lines of a bad sim card reader...I have a new sim card...about a 3 days old, got it from t-mobile cause i had the older sim with the larger gold contact patch. The phone is already on order...they said 7 business days..

This is a tricky subject to cover. I have been involved in a few discussions about this. I am unable at this time to post links to threads.(I am at work) if you pull up my profile on here and look at topic I have posted on should help you in the rite direction. Every thing you have listed in your open is covered in a discustion some where....it most likely is all barrier deep. if you need further help post back here. I will help as much as possible.

Can't you just do a hard-reboot? Hold down Power + Volume Up

Yes some times that will work. Other times might take 2 reboots. Also sometimes toggleing airplane mode can bring back apn. After a few sim cards and all my problem went away. When I had the issue I was cm7 rom. Stock Rome didn't really seam to have this issue.

just to close this thread I already received my replacement phone from tmobile. I am no longer trying to track down the issue. Thanks for all of the replied and comments. every one who contributed will get a thanks from me.

Yes doing a hard reboot will reset the Apn/data loss problem. (Also toggling airplane mode would some times reset it.) This is only a tempory solution as it could happen again. On cm7 rc1 it would happen to me at least once a day. As well as many others. Off of the top of my head it was something wrong in a radio file.(? Not sure what file) shortly after the release cm7 stable 7.1.0.1 was posted. I believe that had the patch for the data loss issue. It is possible that some cm7 based Rome may still have a data issue loss as they might not have the updated patch. At the time stock based Roms did not have the issue and as far as know. Some people faced with this issue could have had a faulty sim or phone. The other thing that was happening during the life of this issue was how many people running cm7 based roms didn't have the issue. I no longer have this issue. I followed the bug report that was submitted and sealed out the sim card twice. (I think it was cm7 issue on my device) OP- I hope that this swap works for you. If it don't, I will be more that happy to help. also thank you for your service.
I have posted what I know and can remember here in hopes that it can help some one else out in the future.

When I had the phone I installed CM7, and the daily's...ect..It WAS a phone issue (hardware) I now have had the replacement phone for 1 week and no issues what so ever. That's not to say that the issue will arise again? I have rooted and am running no ROMs at the time but am thinking of going back to the FROYO 2.2 just to get the camera like it was in the older version. I hate the camera in GB 2.3.3. No zoom....c'mon LG..where did you guys lay down to sleep during this process if the development? One other feature that has nothing to do with the camera that I would like to see happen is to be able to enable a bluetooth mouse. I tried my Targus mouse and no luck. I think you can use a bluetooth keyboard but have none to test. I was thinking of shelling out the 160 smackers for the infared keyboard..small and can fit in your shirt pocket, and it's bluetooth.

[Q] Radio issues with Nexus S, Hardware problem?

Hi,
My Nexus S is having a strange issue that when turn the phone on it picks up that I'm on Orange UK but from then on it says emergecy calls only or no service but shows signal in the status bar. If I try and call someone I get no mobile network messages but I can get a data connection and use the Internet although very slowy. Strangest thing is that if I put no sim card in the status bar still shows signal.
I've tried different radios and tried both Offical stock 2.3.4 and CM7 7.1.0 but same results, I've also tried turning 3g off but I'm now out of ideas so can anyone give me some tips please?
Thanks

Can you give specifics? Phone model, Baseband version (found in Settings >> About phone). Not all radios are the same and you can end up bricking the phone flashing wrong radio version.

You cant brick your phone flashing the wrong radio....youll just have to have the correct radio as a back up. I flashed every radio for the nexus s and its not bricked.
Anyway, the standard radio the i9020a comes with is the UCKF1 or KB3 as I have heard. http://forum.xda-developers.com/showthread.php?t=1116884 is where you will find the radios. Just flash the correct one. How you will know whats the correct one is it will be stated after the phone model. for example I9020AUCKF1 the A after I9020 is for the carrier ATT and after the thats the radio it came with. just reflash the correct radio through CWM and you should be ok. If not PM and I will help you further

Flashing I9023 radio on I9020 will brick the phone as it may not even boot into recovery, fastboot may not work too. Just a word of caution.

What the next step would be is to try a new sim card. Go to your carrier and ask for a new one. If same results then its the phone and I'll assist you more.

Managed to borrow someones sim card at work today and it was the same result so it does seem to be a hardware problem now.
Sent from my GT-I9100 using XDA App

Yes. That would seem to me like the problem. I'm sure you restored your phone and completely wiped the SD? Also did you try pulling out the battery while the phone was on wait 30 seconds try turning the phone with out the battery then put the battery back in and turn it on? I'm sure you have done that you seem like a decently tech savvy fellow.
I've called Samsung before and I hate to say it but their repair policy is horrendous. You'll need another phone cause you'll be without yours for 2-4 weeks. They want to send "you your original phone back." Even their battery exchange is the same. You send your bad battery to them. They receive it process it then send you a new one. Motorola and apple have their repair department to be easy and quick which is what the consumer wants. More so apple cause you can go right to the local store and get a new one in 10 minutes. Motorola takes 2 days. Better than Samsung still.
Thats it for my rant! Just wanted to give you a heads up of what you will hear. Hope it all works out.

yea, try flashing a CDMA radio on a GSM phone and see how that works out for you!
edit: actually, this sounds exactly like the ns4g i bought the other day. try making an emergency call and see what happens. really, that's how i fixed mine.

I've had a similar issue in the past. Restoring my EFS made it work again.
But before that issue, I also had another problem where no amount of radio flashing and EFS fiddling would fix it. Sent it to Samsung and it came back with a form with a hand written note saying "BGA failure".
So I imagine this problem is more common than it might seem. *shrugs*

Restoring the EFS would have been one of my first moves but I was given the phone in this state with no backups made.
Just crossing my fingers that Samsung doesn't charge me a king's ransom to repair it.

G2x Weak Wifi Signal?

My g2x is currently on MIUI 2.3.7
My g2x has been acting up on the wi-fi recently. And I know it's not the router, it's the phone. Even when I'm at the public library I only get one or 2 bars of wi-fi signal, sometimes it won't connect at all, sometimes it will but it will disconnect within 10 seconds. When I'm at my friends house I place it next to the router and still get only 2 or 1 wi-fi bars. Maybe a hardware issue? Idk. I have done the process of resetting, flashing a different rom, and relashing again but to no avail. I also tried looking for g2xfixwifi on the market but no results. Someone help or same thing that happened to anyone

My g2x locks onto networks almost instantly, are you fully wiping phone when installing new roms? I reccomend g2x scrubber or bo®ks nullifier .zip, ive tried every rom on this g2x back when it was my only phone and they all worked fine.

It may be the way your holding the phone, the wifi antenna is on the top of the phone, and when i hold near the top of the phone or with my finger over the top i will instantly drop a 2-3 bars, then right when i take it off it comes back, kinda does the same thing if you have it laying on a flat surface, try holding it at the very bottom and have the back and top exposed

JB 4.1.1 Won't connect to tmobile towers

It updated OTA on it's own and was working last night. This morning I looked at my phone and it was connected. I moved it and it lost signal and hasn't gotten it since. I can't force it to connect, will get roaming but roaming in this area is emergency only.

Just did that. Still nothing.

Ok I've flashed 4.0.4 then CWM to 4.1.1 and nothing. Flashed 4.0.4 and nothing then flashed GB on it and nothing. I'm out of ideas.

Maybe you didn't save properly? Don't press back when done inputting everything, but press menu>save.

If that doesn't work, there's a remote possibility it's a problem with the SIM card. You might want to go to your carrier store and ask for a new one; in my experience this is usually free. Other than that, if flashing a whole new ROM doesn't fix it, I have a hard time understanding how it could be anything other than a hardware issue.

It was the sim card. I wished I would have thought of that before I wiped everything though. Oh well I got a clean install and learned a lesson. Never skip step 3...

Issues with my skyrocket (used)

Guess i should start from the top here..
i purchased the phone used from a friend, the phone was having issues with crashing and locking up,
as well as constant signal loss/and wifi was also causing crashing (gingerbread 2.3.5)
so i flashed CM10.1.3 stable it's no longer random crashing, Wifi is still causing reboots(but no more locking up after booting)
tried flashing a radio for it to fix the signal problems, and no dice.
could this be in the hardware since the radio didn't seem to do crap
On Monday I'm going to try and beat a refund out of my friend for selling me a faulty phone
so if i can't get it fixed by then it's not my problem any more
update: I flashed "AT&T 2.3.6 OTA Update Radio I727ATTKK1" it actually fixed my wifi, but now i'm getting no signal at all, attempted to make a phone call and it just says "Mobile network not available"

my power went out mid-download of the stock firmware, and thanks to some retard they're uploaded on hotfile, which allows downloads every hour thirty.
so i'm gonna go GTA5 it up for a bit and then come back and try again.

First off you need a jellybean radio for using cm 10.1.3 that's why signal was dropping

Might as well check your APN while your at it. Is it set to wap.cingular or pta? Settings>Wireless & Networks More>Mobile Networks>Access Point Names. Which ever one it's set to change it to the other and see if the issue persists.

Took it to another friend, says it's water damaged, and the GSM antenna is fried, just gonna get a refund, and go buy a retail one, screw buying used.
