I don't know what's wrong with this g2 - G2 and Desire Z Q&A, Help & Troubleshooting

alright here it is my t-mobile G2 won't connect to the t-mobile network at all, I've went through 3 SIM cards because this thing use to kill the SIM card from working on other t-mobile phones and it works perfectly fine on at&t network. so I've unlocked so it will work on at&t just to see if it would work. so i gave p and bought a MT 4G, but i still want to know if the G2 is fixable because I'm just about ready to throw in the towel this is what I've tried to resolve the problem called t-mobile they ended up saying just return the phone but i can't since i didn't buy it from them. Called them again got the unlock code. I've flashed the radio a few times. I've also just got the leaked 2.3.3 update and nothing has worked. It find t-mobile network but says your SIM card isn't allowed to connect to this network then after trying again it says unable to connect to network please try again later.
Just so frustrating i don't know what to do just about to say forget it. this thread is my last resort.
also i still have S-OFF

I'm having trouble following your story, its a bit jumbled.
Did the problem connecting with T-Mob start after you applied the unlock code? Its a know issue that using the unlock code may cause the G2 to stop connecting to any network.

Also, I've seen it commented on here that T-Mobile doesn't care if you were the original buyer of the G2 or not, they will still replace your phone on warranty. You can ask them to confirm.

Sorry for the delay....it was having problems before I put the unlock code in. I only put it in to see if I could connect to another network

You've tried to fix it in hardware (ROM, radio). So it might be a hardware problem, like a damaged SIM tray (particularly if it is destroying SIMs). As mentioned, I'd try sending it in on warranty. Others here have claimed that T-Mob will replace it, even if you are not the original buyer.

T-Mobile HTC G2 "Unable to connect to network"

EDIT: Just got off the phone with T-Mobile Tech Support, they tell me theres nothing more beyond a Factory Reset that could help the issue, and seeing as I've already done a factory reset a few times to no avail, I should look into getting my money back for this device.
Okay, so I purchased an HTC G2 from ebay. I know this was my first error in judgement, but I have a limited budget so i took what i could get.
Anyways, I currently have T-mobile on my Unlocked Iphone 3GS, but I've grown tired of Jailbreak problems and using 2G data speed.. So i Found this phone on Ebay, and purchased. when I got it, I quickly popped in my already active SIM card and got NO SERVICE, looked around on the phone and found the Network Settings, went to 'Network Operators' and searched for a network. T-Mobile and AT&T shows, but does not connect to either. when I inserted another T-Mobile SIM card, the same error shows. ( thought maybe my SIM was too old to receive 4g or some BS like that.. lol)
anyways, I dont need to Unlock my phone, I dont plan on using it on any other provider or in any other country. All i want is for it to work with T-Mobile, in america. is there anything I can do? or should I just send it back to the Ebay seller.
any information needed, let me know and I can get for you.. its running:
Android 2.3.4.

Is try a factory reset. Re insert sim. If still doesn't work call t mobile support. If still no go file an eBay complaint and send back broken phone for a refund.

Okay, thanks I'll try that right now.
Also, do you think T-Mobile will offer support to me, although i did not purchase the phone directly from them? They got testy with me a while back when I was having issues with the Dash.
Okay, so I just tried both Soft and Hard factory reset and neither worked. re-inserted SIM and still get either "this SIM is unsupported" or "Unable to connect to this network"
I also get an Alert on the Drop-down menu that shows " the network (T-Mobile) is Unavailable.

How old is your SIM? The G2 uses a newer SIM; go ask for a new SIM at your local store

Thanked you instead of quoting! Oh well, this was useful advice actually.
He is right - I had to get a new sim card when I got my g2 in order for it to function as a phone!
Oh, see then I suppose I wasnt wrong in thinking that then. so, If I go to a T-mobile and just get a newer SIM card, all should be well?

My SIM is about a year old, I also tried my sisters SIM which is a bit newer and receives 4G on her LG Optimus, I can still try to get a new SIM though, my question is if its free or not?

yes its free just tell them the sim is malfunctioning
Thanks, but after talking with T-Mobile tech support, we've found that my sim is up-to-date enough to receive 4g, and if its working in another phone then thats not the issue. it appears that the phone itself is malfunctioning in some way that prevents it from receiving any network. I've contacted the Seller and she's agreed to a refund. this is a real disappointment but its the only option left for me.
Unless anyone knows how to fix the problem of the G2 not accepting any network. After some research I've found this to be a common problem after an attempted Unlock of the device that went wrong. but, I've found no clear solution to it. Just alot of people complaining about it. I didnt attempt any unlock of this device, nor did I buy an Unlocked device purposefully.
the sad part is, I've only had the phone for two days, with NO SERVICE and i still love the device. IF i could find a more trustworthy dealer, without spending close to $100 more than I already spent, I'd love to use it.

[Q] New T989 never receive unlock message

I have a new T989 I bought without a contract. I have a Simple Mobile sim card. I have rooted and installed Juggernaut Rom. Before I rooted and now no changes in the fact when I install any sim I get no message of invalid or a place to enter unlock code.I know SM is suppose to work without unlock. But I havent been able to get SM to work at all. Do i need to flash another rom, because it seems that Im locked into Tmobile so far. Any help much appreciated!

Which .apn are you using? are calls working with the exception of data and mms?
Sent from my SGH-T989 using XDA App
I have not changed the .APN. Nothing is working , there is a circle with a line through it in top status bar. Just get " mobile network not available" Im lost at how others have used Simple Mobile sims with nothing extra but to configure the mms/internet.
simple mobile is tmobile, you can use a tmo phone without unlocking with a simple mobile sim, i still have my simple mobile sim from when i used it on my vibrant, and i was able to make a call from my sgs2 without unlocking, so i might be wrong but you should try with an at&t sim, the apn settings for simple are on their site also.
Weird, I'm experiencing the same issue.
I believe the Simple Mobile SIM card is fine, because it works in /other/ (non-smart) phones such as my T-Mobile branded Motorola V195 and Nokia 6030 - I can place and receive calls and text messages.
But the Samsung Galaxy S II T989 is always stuck on "Searching" on the lock screen, and Settings: Wireless and network: Mobile networks: Network operators: Search now: only turns up "T-Mobile" and "AT&T" under Available Networks, both of which say "Your SIM card does not allow a connection to this network" when I tap on them.
Oh yes, and I did program the Access Point Names (APNs) as per Simple Mobile's instructions, twice.
Both with the stock ROM, and with Juggernaut-v4.1 (as it so happens). Baseband version T989UVKL1.
I'll try and find someone with a working T-Mobile SIM card, test that in the phone tomorrow, and report back.
Sim is prolly bad I had same issue when I first put my sim in try another simple sim, maybe sticking it in non smart phones Burns something cus that's exactly how it went down for me:/ when i was using an older phone as a temp, then bought the sg2 and didn't work try using ur sim on another smart phone if it doesn't read it it's toast like mine was

I tested a coworker's T-Mobile SIM card in the phone and had exactly the same problems (no network/unable to find network - just AT&T and T-Mobile), whereas my coworker was able to use my SIMPLE Mobile SIM card in their phone successfully.
I flashed my baseband from to T989UVKID *, and the behavior is the same - still saying that it's not registered, and still only shows AT&T and T-Mobile when I search for networks. Co-worker's SIM card still doesn't allow me to connect to T-Mobile, either.
I'm starting to think the IMEI for this phone might have been reported stolen, and maybe it's being blocked externally (I did buy it from a pawn shop eBay seller - albeit one with good feedback). Hopefully T-Mobile can tell me if I call them up.
*-Well, I loaded the zipfile from topic "1426001 - [RADIOS] CWM Flashable Modems" onto my sdcard and applied update from zip, and Settings: About phone says "Baseband version T989UVKID" now.

Ya sounds like that. You know what my brother had a vibrant brand new from someone on cragslist and then several months later his gave same problem. He was on Simple Mobile. He called t Mobile and believe it or not said they don't black list phones and say it is not possible for them to do so. It was different reps too that said the same thing. I don't know. Maybe true?

IMEI blacklisted
I just borrowed the SIM card from a coworker's AT&T phone. I had to unlock my Galaxy, but I'd purchased an unlock code a few days ago before I realized that the problem wasn't a SIM lock.
Sure enough, the phone works fine on AT&T's network. 2187 kbps down, 436 kbps up, 105ms ping (in my area).
It's definitely the carrier blocking my phone. Now to see if I can return it. Hey, it will work on the AT&T network now, or maybe the seller can catch the person that sold them the phone.
P.S. Judging by the threads on support.t-mobile.com, Support L1 doesn't have access to or know about the IMEI blocks, but L2 does. Case in point:
support.t-mobile.com/thread/15348
Incidentally, I don't feel that it's T-Mobile's fault that I got a blacklisted phone, although I would like it if they *published* their IMEI blacklists. In Australia, you can punch in an IMEI code and see if it's blacklisted.

Finally I brick my E973,, :(

Couple days ago my beloved Bell E973 wont reay sim card.
Here is what happed. the original from bell, but I bought a unlocked code to use my Rogers sim. It's working perfect for 2 or 3 weeks. I love the screen. personal I like it bettter than S3.
I did not root or unlock the bootloader and one day when I put sim card in, it just said NO SIM. I tried with bell sim. same
So I rooted and tried all kind of ROMs, even F180S. that's fun. but still wont read sim.
If anyone buy it as a parts or want to fix it. let me know. I am in Toronto
You tried to re-unlock it ?
Also, if you flashed korean firmware, your radio will mostly be gone.
no really to re unlocked it, since I tried my friends Bell sim. doesnt work

It's still under manufacturer warranty

Two things about your phone:
I may be interested in it for parts, depending on price of course. Mine has a dead spot in the digitizer, and as I bought it second hand, LG won't warranty it for me. I'd not want to spend more than the price of a screen/digitizer assembly, so it might be worth more to someone else.
Have you tried a different sim in it? If the phone is unlocked, try a friend's sim card, maybe your sim just died. Edit: missed your reply about trying your friend's bell sim
Have you tried a hard reset?
Have you tried reinstalling the original rom, using the original KDZ file and the "unbrick" method?
Can you browse internet, play store, or use any program with data connection via wifi?
- first, it might be the unlock procedure did it. I had 2 out 5 devices ran into this scenario after doing a factory unlock.
- second, but unlikely and super scarce situations, Bell might have locked up your device's IMEI that caused it. I got one relative that the carrier locked up his phone after doing a factory unlock.
My Rogers E971 stopped recognizing SIM cards yesterday. It is unlocked/rooted. Hoping I can reroot/lock bootloader and send in for warranty service. Still trying to figure it all out.

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.

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 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?

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?

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.

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 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.

[Q] AT&T i317 - no mobile network

Hi all. I am having an issue with my phone. I bought this phone and it was running on 4.1.1 stock. I wanted to unlock it for T-mobile using the free unlock method (sha256_off). When I put in my T-mobile microsim (which was cut from regular sim) I cannot connect to the mobile network. Instead of bars I see a circle with a line through it. I tried a friend's ATT microsim and it acted the same way. Does anyone know what else I can try to get it to work? I called ATT to verify that the IMEI is clean and multiple reps confirmed it is.
The other question I have is if this is some hardware issue can I still get the Samsung warranty to fix it? My phone had the glass replaced (not full LCD), would they reject the warranty for that reason if I sent it in?
Thanks so much!

Did it ever work before you did the unlock?
Once it is opened by any repair shops/person other than Samsung your warranty is void. They may take it in for repair but it will cost you money.
Trying doing a firmware recovery via Kies. Just search on how to do a manual recovery by putting your phone into download mode and also having your imei ready in hand. This will/may get the phone back to factory stock. Hope that helps.

No signal bars usually means no compatible modem or data is disabled. Try an at&t sim and see if data is turned off.
Also check your APNs, no apn, no service... They should automatically be downloaded from the carrier, usually.
