It seems to be a casual problem but in my case its not. My phone was working fine untill one morning i woke up and there was no signal , my first though was that maybe baseband earsed during updating progress through the lg tool , so i started to flashing the right combo of custom roms and basebands and still nothing , later i tryed to flash the official stock kdz GB (V21E its the right for my carrier i tryed others too like V20A) still nothing .. my next guess was a hardweare problem so to gave it to a good local store that thr guys checked the hardweare the antena the rf chip and some other things but they work complete normal ! so they tryed also to flash the right kdz basebands etc cause they believes that i did somthing wrong ..still not signal .
yes there is IMEI number in the phone only unknown currier and 0db signal evem APN's are correct
we tryed others sim cards from many carriers but nothing for now i use a device of 14euro and my sim works fine like all othere phones.
If anyone can help with this ...
Thank you for your time !

if it WAS working then suddenly didnt, my first thought is you've jerked the sim card loose and not realised. that basic check appart, it does sound like baseband. Download getRIL from the market (if you have wifi) and check which baseband is installed. dont (like i did) install anything get RIL asks you to. have you also tried another sim card? maybe yours just went bad if its been reflashed by KDZ by a third party and still hasnt worked

First thanks for your time . Yes i tryed many other sims of my fiends and as i said i use my sim to another device and works right . Evrything works right except gsm signal i was very careful for what i flash .. the right combo of roms and basebands as the creators of each rom suggest. but even with the official stock kdz the problem remains .
i downloaded getril as u said it says that ril and baseband are correct. RIL : LGP920-V21e-apr-19-2012 , Baseband : LGP920AT-00-V21e-EUR-XXX
As im not an advanced user (see all my aaaaagh its gone wrong) posts all i can suggest is basic stuff id try. If everything seems fine from a software point of view and your sim works fine on your friends, maybe your sim slot just needs a quick clean. You could also try a friends sim from another network and see if you get any sim pin prompts (indicating that its at least reading the sims)

It can read the sim fine however says no servies the same thing hapents with all other sims of different networks. pfff i start believe that is some kind of curse or somthing hahahah

After Hard Resetting my Motorola Atrix 2, when i tried to connect to google account, I am getting an error message saying - Can't establish a reliable data connection.....
Below is the whole description of the problem....
4 days ago I updated my Motorola Atrix 2 with the Update. The Update downloads successfully but after rebooting I got a message saying "Update Failed".
I tried updating again but received the same error.
And 2 days after this updation process I noticed that I am unable to sign into my Google Account. None of the Google Application was opened. All I see the Window with Loading Symbol and nothing else. Neither Android Market, Nor Gmail or Youtube works. All stopped working at once.
I than searched the Internet and find some solutions saying that you need to hard reset your phone.
I did that also, I used both the method for hard resettig, i.e. 3 button method as well as Factory Reset option, but it didn't solve my problem at all.
In fact now at starting of the phone when i tried to connect to my google account, an error comes saying - " Can't Establish a Reliable Data Connection "
I had searched your forums also and find a similar thread
http://forum.xda-developers.com/showthread.php?t=780545
But trying all the method given in this thread I am still unable to connect to my google account.
Kindly Help me......... Thanx in Advance
Go to Settings -> About Phone and see, are you on 2.3.5 or 2.3.6?
If you're on 2.3.5 then you can manually update through Recovery. If you're on 2.3.6 then you might want to try flashing the fxz and then manually updating through Recovery.
You might double check your apns, Might try pulling your sim and battery for about 10 or 15 min to clear your location, you should register and connect to the nearest tower after boot up. I had that issue once and it was actually the market causing the problem. Make sure it's up to date and all good.

I tried many options but none of them seems working for connecting to my google account.
Than I removed My Memory Card and SIM from the mobile and connect through WiFi and I am able to connect to my google account.
The Market, Gmail, Youtube... everything starts working..
But as soon as Placed my SIM back and tried to connect through Edge/3G network i am still getting the same error and market and all other google apps just showing Loading....... even though with the same settings Internet on my device works perfectly fine.... Browser is opening all the sites pretty cool. But I am stick on the Default Google Apps that come preinstalled in the Android.
Plzzzzzz Help me guyzzzzzzz...................
Alright... I'm not quite sure what is causing your problem but I can bet that flashing the fxz will solve your problems.

Which service provider are you using? If you're not using AT&T I imagine you have the phone unlocked.. Could something wrong have happened with the unlock?
Does unlocking stay with the phone even after a fastboot flash?

Yuppp....... u r right.... I have an unlocked Atrix 2...
I am an Indian and I uses Vodafone Sim here.
And yes even after Fastboot Flash, it is still unlocked.
I was also worried when i was going to do a fastboot flash about unlocking issue.
But than i took the risk by my own and atleast after fastbooting it didn't get locked back to at&t.....
But no help regarding my issue of unable to connect to google account.
Though it works very much fine in WiFi but through SIM I am unable to do anything on google apps.
I had changed and tried the several APN's but none of them helping me...
Neither all other methods, such as Factory resetting, Youtube trick, etc , dont help me at all...
Still m searching for the solutions

Try another SIM card from your provider. This phone does have issues with SIM cards and weird things like that.

Flashing the fxz will not fix your issue, I promise. And I am not sure running SC v5 is the best option since you are having some issues. SC v5 is great, but it has some GPS issues, and a couple of other things. Since you are having this issue ONLY while using the cell singal, that should tell you that the issue lies on that part of the signal, and should be a very good lead in fixing it. I would talk with your phone provider.
Do a search on this forum for issues with atrix2 and SIM cards, this seems to fit the same bill we have been seeing over and over with phones that are not on a "true" HSPA+ "4G" style SIM card, there are even some people that had 2 of the same exact cards where one worked and the other did not. I would post a few links in here, but there are just too many to even give you a good few, to look at.
Jim
I have the same problem here.
Because sc v5.2 had a gps issue,then i go to bootstrap,wipe cache partition and wipe factory then restore 2.3.6 deodex and rebooted.
And now i can't connect to my google account.
Tomorrow i will try to restore sc v5 again and wish it will solve the problem.
Update: Restore sc v5 and now i'm able to connect to google account,but now i got fc.

Problem Solved
After so many hard reset, at last I am able to connect to my Google Account.
The most interesting fact is that problem is with the SIM's APN only.
Here in India, Vodafone provides two APN, one is "WWW" and other is "portalnmms".
I had tried both one by one but that didn't seem to work, than i found a thread on internet saying that add both the APN in a single APN, i.e., "WWW" in the APN field and "portalnmms" in the server field and change "Authentication Type" to "PAP" and leaving all other fields to default.
I did this and as soon as i saved these settings, everything starts working.
I am more than happy....
Im Having Problems with my G2x Yes its Rooted it was working fine for a couple of months then today i was just texting and it just rebooted and its like it cant read my SIM card i cant get no signal So can any body help me?
It can't get no signal? So then it does get a signal. Anyhow....
1. Try turning airplane mode on then off
2. Try rebooting
3. Does it say Invalid SIM? Because if it does that's one thing if it doesn't it's a phone issue and can be caused by some ROMs
4. Repeat 1 and 2 above but standing out side where there is no question of signal quality.
5. If at this point you still have no signal tell us what ROM and kernel you have, and under volting or over clocking.

go into recovery, and try wiping cache, see if that fixes it. if not make a backup and wipe data. if it still is not fixed then try flashing a different ROM (even a gingerbread one if needed) and post back what you find.
if none of this helps your sim card might be busted, in which case call your local t-mobile store

did you follow the directions above?
if you did then one last step you can take is to use the LG KDZ flasher tool to completely and 100% restore the phone to factory condition (do a search in the development section)
this tool has been know to brick phones, so only do it if you have done all of the above things that i suggested.
if that doesn't work then it is most likely a hardware problem, which means you have a phone sized tablet now
I flashed the new Bricked kernel today and it messed up my APNs. I can't change the MCC and MNC values. If I try to the APN won't be saved.
I already superwiped and reflashed everything even with different kernels but the problem still exists. My phone shows it's roaming and I don't have data access.
Now there's even a carrier list that wasn't there at all before.
Someone suggested I should remove market access emulate on boot, but I don't know how to do it.
Any help will be appreciated.
Thanks!

No that does not help. I was on the 3.33 firmware and I even reverted back to 3.32 and an older radio to try my older setup and see if that fixes it.
I still have no data Phone still roaming
Now I even flashed an old stock GB rom with old Hboot and old radio.
For some reason the phone still thinks I'm using Vodafone...
I tried APN Backup & Restore. When I backup the APNs it saves a xml file with a lot of carriers in it. Way more than what the phone shows
in the system.It only shows the Vodafone ones. Heck, I even have a carrier named "My Dads Internet" which is also weird.
I really have no idea what to do now, should I get a new SIM card?
Please help!
Well... 2 days of trying to figure this out. No solution.
Maybe my SIM card thinks I'm outside the country. I guess I'll have to call my service provider and see if I need to get a new SIM.
:/
Wow this is terrible ! I've never heard of this happening! I would definitely call carrier and see if you need a new sim card or what can they do on their end to fix the issue, especially if none here knows a fix or responds. I just wanted to wish you the best and let you know I really hope your issue gets cleared up soon! Please let us know what happens and what the fix was ok. Good luck to you!!

Thanks, I just put the SIM card in a friend's phone. Same problem, so I'm glad to know the problem is with the SIM card and not the phone. That's definitely a relief.
I'm calling my carrier!
Just to close this thread in case anyone is suddenly having this problem, you either installed Market Access or Market Enabler or your SIM card is just not working correctly.
My problem was the SIM card, I got a new one from my carrier, everything is working again
Hey guys,
No matter what I do I can't get my service to work again. All it shows at the top is a little circle with a slash through the middle. I tried installing a custom rom but ran into some problems. So I "restored" my backup through rom manager. But i don't have service anymore. Since this happend I have tried several new roms and I still can't get the service to come back.
Some people say it has something to do with the IMEI but according to my setup I still have one.
I have been working on this problem for nearly 13 hrs none stop! Please help... I have searched everywhere.
Thanks

If your IMEI and all that information is correct then you may have a bad sim card resulting in no service at all. Otherwise i'd recommend using odin to go back to completely 100% stock and see if that fixes it.

Thank you so much for responding. I have tried to restore stock with odin but every time odin finishes my phone still boots up my existing rom. Any quick ideas with that one?
And do you really think my sim could have just gone bad like that? It's free to get a new one so maybe I will try that as a last resort.
I don't know much about rooting but could it be my radio?
A couple of questions?
Is boot loader unlocked, if so how did you unlock, updated ver 1.4 ez-unlock can mess up and relock boot loader. Use ver 1.2 . "Verizon only"
What ROM and kernel? Make sure its for your carrier.
Any radio should be OK as long as its for you phone and carrier.

did you try reprovisioning your device with dialer code *2767*3855?
note that this does wipe internal sd so back ur **** up!
I tired the above number in dialer but always comes up with error saying "mobile network not available".
Am I doing something wrong?
Oh.... You forgot to ad a # on the end of that number. After this everything started working again!!! Thank you so much!
