Hello everybody, I'm writing you from UK, where I bought a second-hand G1 (absolutely perfect!!! really good). The phone is T-Mobile branded and factory-default cleaned. Once I got it, placed my italian H3G sim inside, and (of course...) it told me that it was locked. I purchased a key (...I know may I could do without it... but very few time to spend, these days) and it was succesfully sim-free. Then I reebot it, and start the acrivation... that doesn' run!!! I insered the correct APN parameters, I also tried with a UK O2 and Vodafone sim, but, problem is that the gsm segnal level (small icon on the top with 4 vertical bars) is not giving signs of life, and it has a small "cross" on the left side. Of course I can't get the registration... I can't get the line!!!! why does it happen??? all the sims are correctly recognized (ask for the pin and the "no sim" messages and icons are off), but no way to go over...
Please, help me in any way, just 1 more day here, then I'll go back to Italy... far from the shop!!!! HEEEEEEEEEEEEELP!!!!!!!!!
If you type:
reboot
and press enter. If the phone reboots you can have a chance, if the phone does not it means its on a updated version which you will have to downgrade. While downgrading i recommend going up to Rooted versions of android. Although you might not need it.
You should look here:

You can get through your problem, if its just the registration. by simply following a few of the instructions in the first link combined with some of the instructions in the second link.
@elmejor: He didn't even mention rooting. His problem is he can't get his phone to associate with the networks on his sim.
@tony_m78: You should probably post what apn settings you are using. Also, this is NOT A DEVELOPMENT ISSUE and should not have been posted in this forum.
thanks gor your answer.... I have been to those links THOUSANDS of times, within yesterday night and today... but I really can't get a solution. I can't go over the "error connecting to server" page :-(
The worst problem is that I really don't have time NOW, but I'll have it at the end of the week; I know I'd get a solution, working on that... but really I can't. But whay do you think about the absence of segnal? is it normal?!?
Tomorrow morning I'll find the way to buy a T-Mobile original sim and try to see what happen. . . . . . but that's strange!!!!!!!! not normal... i insered a correct code (generated from the IMEI), the answer was "unlocked", free for others carriers.... BUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU!!!!!!!!!! :-( tic tac tic tac. . . ..I don't have time!!!!!!!! :-( nobody experience this strange problem?!?

...I don't think the problem is the APN, I set the correct one (from Wiki) for H3G Ita and for O2 UK (these are the sim I tried with); the problem is that the segnal is ZERO, like the sim is not present... BUT IT IS, it ask me for the pin and accept it....
Can you manually select the network to connect to? Settings>Wireless controls>Mobile networks>Operator selection
Are you sure radio is working on this phone? Maybe it has some physical problems (like bad gsm chip)... Or - maybe you have sim cards not acceptable in UK.
Try with T-mobile sim first. If not working:
I would try to factory reset device some times, if it don't help I would try to reflashing it (firmware and radio). But in your case I think you should ask about this situation in shop where you bought it (if you have warraty) first.
Data plan?
I had a similar problem when I got my APD1 phone in the US. When I returned to the UK, I put in my Tesco SIM and the phone signal strength icon had an 'x' indicating not connected or no signal. Eventually I used my home wifi to activate the phone. After the phone was activated, the same SIM was able to connect and the signal strength icon worked normally.
BUT, it turned out that all I probably needed to do was to have a SIM with a data plan (which mine didn't at the time) <<BLUSH>>
Have you confirmed that your SIM has data turned on?
Of course ensuring that the APN settings are correct is also necessary. (But it sounds like you did that)
Hi
I have a big problem with my N1, this day i used my phone as normal, calls, web and so on...
Now my phone are completly unable to connect to my provider Telenor, i have tryed the sim card in another phone and that works nice so the problem is the telephone.
My phone is a "Open phone" with this info:
firmware:2.1-update1
radio:32.24.00.22U_4.03.00.21_2
kernel:2.6.33-msm-tek...
buildnr:ere27
I have updated radio with:TheOfficial_Nexus1_Radio_Update_4.03.00.21_2 (for ere27)
I have wiped and installed my NexDESIRE-v1.2_REMIX two times without any luck.
WLAN works nice.
Are there anybody else that can help me?
Thanks
Regards

This was an odd problem.. I my self have a N1 running with a Telenor simcard in Norway, and i have had no problems, have been running Stock, cyanogenMod, + other roms, and never had any problems like this, now i'm running 2.2 and no problems what so ever..
Try Flashing the new 2.2 update this includes a new radio image. Remember nandroid backup first!.. and WIPE everything just to be safe..
LINK:http://http://forum.xda-developers.com/showthread.php?t=686631
This could also be that your phone are trying to connect to Netcom instead of the Telenor network.. try this steps:
Settings > Wireless & networks > Mobile networks > Network operators > then select Telenor from the list. If every things ok, it should say "Registered on network" (sometimes the phone use some time searching for network operators).
BTW..: Wrong section, this one should be in Q&A
Hmm
Yes,this is pretty wierd sinse i have used this ROM for monts now without any problems.
I have read all evening but no luck...
The link you gave me did not work :-(

try froyo, thats my only/best guess on getting this to work again. Worst case call HTC. So you have tried the method selecting network operator manualy?
Jepp, i have tryed to change manualy between Telenor and NetCom but none for them will work, i now also tryed to load the phone with the ROM you suggested but no luck...
So sad... :-|

Thanks, you have been great help
Then i will pick up my Nokia 9210i and call HTC tomorrow.

I had the same problem, it may be a problem with NexDesire.
I flashed nexDesire and over night the radio died on me. I tried multiple different SIM's and ROMS (which I can account that work on my brother's Nexus One fine) with no luck.
I had to send it back to HTC, we'll see how it comes out when I get it back in a few days.
Leave the phone sitting for 5 minutes, if it still hasn't found it try doing a manual network search. If it still won't work, pull the battery, boot up again and repeat the process. I've had to do this 3-4 times a couple of times to get it to pickup my network.
Opps, that dosen't sound good...
This is a little cises for me sinse this is my "tool at work".
Should i go back too Mr iPhone ?? :-|
But thanks for info.

Good night my fellow modders. Tonight i come with a particular query, mainly, how do i go about troubleshooting the 3G connection of the motorola razr i. Ever since i flashed Omar's Motorola 4.1.2 Rom from Jan-01-2014, i haven't been able to get internet access through my carrier (Not even through 2g) and ive already checked its not a carrier issue (Since i can use my simcard to browse the internet in another phone just fine), i even tried doing a nandroid restore from the stock firmware i had previous to starting this adventurous task to get things working again, but even then the mobile broadband service is a no-no.
I'm at a loss on what to do, since i've already tried reflashing the ROM, reset-ted the phones APN's, and i've also done the suggested file modification of the losialert timer to both, 1000 and 500 (as seen in the same thread). However those efforts have been to no avail and im quite at a loss on what to do.
Im sorry if my english isnt fully understandable (Its not my native languaje) and im also sorry if this isnt the righ section to post about it, but i cant post directly in the thread since I'm a new member. I thank you beforehand for any and all guidance or help you can offer me.
Don't worry, English is not native language for most of forum users.
First of all buy any pre-paid card from different carrier or borrow it sim-card from friend and test it.
I had similar situation with Virgin Mobile. We have quite few operators in my country and I tested all of them but for this I wasn't prepared. I had my new RAZR i and there was no option to use internet with Virgin Mobile.
After few days of fight with different ROM, modding system, installing apps to APN's I figured it was sim-card. Some carriers have old sim-cards which have something wrong with MCC and MNC code and all phones can work on it but not Android 4.1 and above caused APN automation.
I even called to Virgin to ask for changing sim-card but they said they don't have different version of sim-cards, so I asked "WHAT, so every people in Your network doesn't have internet on Android 4.1+??!!" and they said "Yes, it seems so".
And there was no other way but change carrier. Now I have fully working internet without any modifications.
Sorry for so long and boring reply but for my almost 10 years working with mobile phones it was first situation like this.

Thank you for taking the time to answer my query. Unfortunately, i believe your case doesn't apply to me, since i had no issue using the internet with my operator (Telcel) before flashing the new ROM. I've also already called my operator and they made several procedures to try and reestablish my service, however none of them worked, but they assure me it's a problem with my device, since their service is working correctly.
I have no idea what to do now, but i hope can get the minimum required limit i need to ask for support directly on the thread ;(.
I don't know if this will help.
I had this problem with my brothers phone (galaxy s4 mini) last night. Data wouldn't turn on in anyway. Flash in new ROM from recovery didn't did the trick, nor a nandroid did. The only way I have got it to work was flashing a stock ROM through ODIN. In this case it would be RSD lite. Maybe it I'll work, but be aware of the flashing problems red lite can give. Read it a bit. Good luck!

Do you have the correct APN entries?? You might need to add it manually...
That happens because it doesn't auto configure (correctly, or none at all) for some carriers because I don't have all the carriers in apn-config.xml -- while your specific carrier ROM might have had it already configured and a specific xml list for them.
If you reset APN's and see all the appropriate ones added it might be configuring a wrong ones by default according to the data from the apn-config.xml one in my ROM, just configure accordingly to your carrier information
Note 1: My ROM does not touch the radio, and since the radio images are international anyway it does not make sense to flash recovery images or anything ... the only problem (assuming you did not break anything in hardware during ROM flashing) comes from the android /system partition which is prone to have incorrect carrier settings for data configurations... any bad number or password updated on your carrier it would be configuring something else by doing "reset to default"...
Note 2: To save the APN entry don't exit ... press the options menu and hit save when done modifying -- else it won't remain saved!
The problem starts when You updated from 4.0.4 to 4.1.2??

Did you try to change the APN settings before you tried this? I'm only asking because I'm considering this option, but i would like to rule it out as my final option, because since i started having this issue I've been reading a lot, and the way you fixed your problem sounds like the stock ROM corrected your issue by giving you the default APN's for your carrier.

I'm afraid i was already on 4.1.2 by the time i installed Omar's custom ROM.

Thanks a lot for getting out of your way to help me Omar; After troubleshooting the device and several talks with my network carrier I've managed to get a so-so signal. I'm not sure if your ROM configures correctly or not the APN'S of my carrier (Telcel) because when i edited them everything was configured as it was supposed to be (I'm not sure about the password since i can't see it though), the only thing that was missing was the APN for GPRS, but I've been reading several forums and almost no android device needs this in addition to the 3G APN (I've added it nonetheless but the device isn't actively using it, my guess is that you've got to choose either 3g or GPRS); I also called my carrier, and the allegedly reset-ed my service.
I'm still not sure if the device is working properly, mainly because the internet access through the mobile network has become very unstable (Sometimes i get disconnected randomly, and turning on the Wi-Fi gets me disconnected automatically), and even though the radio almost always gets an H+ signal (Which is kinda funny, because i used to get 3G more consistently before) i don't think this is normal behavior. I think it may have to be with the los alert, because in my desperate attempts to get things working, i reflashed your ROM and it was set to 1000 once again and I also think that the hardware can't be broken because i wouldn't be able to connect to the data service otherwise.
Because of this i would like to ask two very specific queries, is there a way to flash this setting without flashing the entirety of the zip file?; And in case there isn't, if i flash the zip with the new configuration, and then proceed to perform a nandroid backup of my previous build, will i lose the new 00radio configuration?
I will be tinkering with the device this weekend and will report back if i can find whats wrong, just in case it's something else and somebody needs help troubleshooting this in the future. Thanks to everyone that has contributed so far, i wouldn't have learned so much in so little time without your help.

Hmm, don't know for sure. I have made some changes within the APN list to get it working, didn't work. But the rare thing was that the cm11 one did have data and when he flashed his stock back with a nandroid or a stock zip file data wouldn't turn on anymore. So I can't rule out that it was the APN list that was making trouble, because even with stock it did not work. Only by flashing through Odin it worked. Radio hasn't been flashed in that process.

Hi,
New P10. Inserted my sim and start it up:
How do I get past the prompt "Change to Vodafone configuration"
"Hi it seems like you are using a Vodafone SIM card. Do you want to change your phone settings to support the new SIM? (Please note that selecting this option will reset your device and erase your current settings and data)"
There is only OK button.
I know if I tap OK this wipes the phone. I dont want the Vodafone settings. I just want to set up my phone myself. Vodafone loads a bunch of rubbish.
But this screen seems to be difficult to bypass. HELP!
With my P8 I set up a bunch of stuff and then inserted my sim and LOST EVERYthing!!! I dont want to repeat this!!! There has to be a way out of this!!!

I tried to bypass this as well when setting up my P10 Lite, but to no avail, unfortunately. I hate that there's no choice in the matter when using a Vodafone sim card. Very annoying!
Good morning.
I'm in Turkey for work, and at the Vodafone point, i think the guy did this operation (reset and change the phone settings) without asking me.
Now my huawei P10 have some vodafone app that i can't remove.
After that, in the phone there was not app like play store, chrome, and also the keyboard, so i've made an hard reset.
Now the phone is working, but it looks like a branded phone.
How can i revert to the stock configuration?
Thank you very much

Unfortunately, whether he asked you or not, there is no way around using the Vodafone configuration when using a Vodafone sim card. It is better to do the Vodafone reset as soon as possible, because as soon as you put a Vodafone sim in, the phone will prompt you to reset, and there is no way that this can be avoided. You will then lose all of your apps and data once you do the reset, you'll need to set the phone up again.
If you cannot remove the Vodafone apps, then you should be able to disable the apps in Settings > Apps > Choose the app you want disabled > Disable.
Hi, thanks for your answer.
I know there's no other possibilities, but there are many other operators, and in the end I did another sim, not vodafone.
But this reset has caused me many problems, I was traveling without a phone, and i lost many things on the phone.
I think he was not professional at all.
Now i want to revert to factory configuration, it is possibile or i have to download and flash the firmware?
Thank you
I understand your frustration completely. I'm not sure there is a way for you to get back to the default configuration again. I think once it is reset to a specific country's configuration, it is done permanently, but I am speaking under correction.
Hopefully someone with more knowledge regarding this can help.
If it's not possible, then the only other alternative would be to rebrand your device, BUT that will require an unlocked bootloader.

Hey everyone. I bought a Mi 11 Ultra from china but I don't know why isn't getting signal at all. It detects the SIM but it doesn't let me make or receive calls neither messages, and obviously it doesn't connect to mobile networks. Can somebody help please?
Where are you, what network are you trying to use and have you got some screenshots of your network and SIM settings?
Hey, thanks for answering! Im in Mexico and about the network, any of them. I thought of changing the ROM from the CN to the global one to see if that help, but I need the mobile data to unlock the bootloader, and since the phone isn't getting signal, I cant do that.
P. S. Sorry, what do you mean by SIM settings?
Attached are screenshot of my SIM settings. Yours will be similar. Make sure your apn is set correctly. Make sure your SIM is recognised. Just basic setting checks. May be try other sim slot and of course, make sure it's right way up for either slot.
Without any screenshot I cannot see what may be wrong, so start again with SIM. Shiny side outwards and make sure it is recognised.
Hi again. Yeah, I have tried with both slots for the Sim, each one the correct way, but is the same result for both of them. Thanks for the example of the SIM settings, now I attach mine. As you may see, the SIM is getting recognized, just don't know why isn't getting signal. I've also tried with other company's SIMs, but I get no different result.
Looks good. I think you need to try with another SIM on different network and same. Try this SIM in different phone as it looks all good on screenshot but may be provider has not enabled it properly. If different network SIM known to be working doesn't work in your it must be hardware, hopefully not .
Also look at settings, all specs. Check SIM status and press 5 times on memory for deep phone info.
Hello and thank you again! Yeah... I've tried different SIM from different companys, all of them known to be working, but none of them has worked on this phone. I'm starting to lose hope... But here are the other settings, just to make sure isn't about software
The screenshot show that your radio is off. This is saying that your phone SIM is not turned on for some reason.
There is not much anyone remotely can do, if you are unable to get it turned on.
Maybe someone else has an idea? If not, and it cannot be resolved by resetting the mobile network ( in settings somewhere) or phone reset, then it may be back to seller as a hardware fault. Sorry I can't help. Let's hope someone else can?
Thanks a lot for your effort. Since you told me that the problem could be the hardware, I asked the seller about this issue and he told me that this problem is covered by the warranty, so I'll send the phone back to them. Again thanks a lot for answering!!
Just for info have you seen this thread about att? https://forum.xda-developers.com/t/not-a-recognized-device-by-att.4462649/#post-87088003
No, I hadn't heard about that, but still, I wouldn't hesitate on changing my provider if another one works, but since I tried changing to another provider SIM and nothing happened, I guess it was a hardware problem. Thanks a lot for the info!
Try doing manual search of network. If it shows nothing then try checking network frequencies of your network provider and comparing them with this phone supported frequencies. Sometimes its due to your network provider doesn't operate the frequency which this phone supports.
