Help No Network Signal !!!

Hi i have a brand new unlocked phone but when i insert my simcard phone is booting type the sim pincode, starts up and it says no service.
Ive tried 3 different network providers (prepaid)
Sometimes when im outside i get a signal but its very poor then when im going into a building the signal gets lost and again no service.
Im realy stuck with it cant find answers, tried everything factory reset everytime with a new simcard. I have the latest update. Phone is US version.
Thanks in advance...

Had the same problem with my wifes phone, it worked for about a month then the radio would bounce between 1 bar at boot then fade to nothing, Ive flashed 3 different radios version to it still no go. Ended up sending it in for a replacement only to find out that HTC had a small batch of bad radios in a few phones. Tmobile just swapped it no questions asked.

Should I try to flash with other radio versions and how can i do it? I live in Belgium and got the G1 from Ebay so i dont think i can return the phone. The Seller says that the phone was 100% ok... So nothing I can do about it...

My advice is to check whether the phone has been blacklisted. It's what happened to mine - bought on ebay, was working fine for a week, then just got no service. Phoned up T-Mobile and they told me that it'd been reported stolen, so I then spent a couple of days fighting with the ebay seller, but it's working fine again now.

How can i check that on T-Mobile site? Im not familiar with T-mobile....
Thanks

As far as I know you can't do it online, so just phone them. Shouldn't take too long, just make sure you have your IMEI number ready (which is underneath the battery or can be found by typing *#06# into the dialer).
Edit: Or, the IMEI number can be found in Settings -> About phone -> Status

Called T-Mobile nothing they can do about it... I said if i give you the IMEI... Answer nothing we can do about it... 13min cal from Belgium to US hmmm how much will that cost
Now I really dont have a clue what to do...
Someone else any ideas?

I'm not sure how all this works, but if you're in Belgium, shouldn't you be calling TMobile Europe or something? Can a U.S. blacklisted phone not be able to get service with other providers?

Did not help calling T-mobile... Any suggestions??

Did you install Froyo?

Nothing you can do. However, if you only ever used kies for updates, they shouldn't be able to do that. But your phone is under warranty, so the charge is a bit funny (there might be a charge, but it shouldn't cost THAT much)

He most likely installed froyo beta, do a search as theres a few threads and fixes for it.

IMEI is changed so the warranty will cancel automatically.

The only time i've seen when people got their IMEI switched is when they installed the leaked ROMs from Korea
if you didn't do it, then some body else did, or your got might have been swapped when you didn't noticed or something along the line
the IMEI doesn't change on its own, there is no download able android market software that can do that, as it's againts the law to begin with, and 2 it voids the warranty, and 3 you can be charged of criminal theft for cloning somebody else IMEI etc, etc
so yeah, thes no way that was done via download able software
it had to be plugged in to a computer usin Odin or something along the line, or maybe Jtagged to be able to change that sort of thing
Did you buy the phone from some body else?

[Q] i9000T No signal help

I have a Samsung i9000T that I recently bought from a lady who said she forgot her password to it so she couldn't unlock it. So I bought it and tried factory resetting it so I could sell it to a friend of mine who wants to upgrade from an iPhone 3G. Well factory resetting did nothing, I did some digging and found out that it's a common problem for i9000's to have a csc file corruption. So I decided to flash, via odin, a stock firmware to the device. The firmware I decided on was a UK firmware because I couldn't find an american firmware for it. The flash was successful and I was able to boot the phone no problem. A weird thing was that all of the lady's data was still on the phone, so I contacted her and told her I could backup all of her pics and give them to her, which she happily said yes to. After that, I rooted the phone and installed cwm and then flashed Slim rom android 4.2.1 to the device. I then put a backup sim of mine in the phone and tested the phone. The problem I am having is I don't get any signal on the phone what so ever. I have all the ATT apn's on the phone and they look to be correct.
My question is, having flashed a UK firmware before anything somehow messed up the ability to connect to ATT here in the USA? And what course of action should I take to correct the issue with no signal? My friend is in the military and is being mobilized on the 1st of march so I would like to have a working phone for him before then as I will not see him for some time after.
Any help will be gratefully appreciated. Thanks in advance.

Just a question, has she ever reported it stolen? Has the IMEI number been blocked?
Find out the IMEI number and contact the original Network Supplier that the phone was used on and as them to check this. They'd be able to tell you if there are any issues.
Not trying to worry you but it happened to me. I had to return the phone.

I know the imei, but I don't know the original carrier for the phone... I assume it was ATT because that is the dominant carrier in my area. I'll get in touch with the lady I bought it from and see for sure.
On another note, I've tried testing the internal antenna by inserting a wire into the external port, but still no signal.
I'm going to try completely starting over and see how it goes this time.

Ok, so this thread can be closed now. I've solved the problem.. and feel like such a noob for some reason I was kinda spot on with what i thought was wrong but I had such a hard time finding files to fix it... untill i found this:
http://forum.xda-developers.com/showthread.php?t=1494493
AMAZING guide. Fixed my problem right up. Running 3G here in Texas on ATT. My friend will be so happy that he gets to take an android back over-seas with him.
Thanks to all of those who helped, I greatly appreciate it.

Rooted phone won't connect allow phone calls or texts.

Hi,
I recently rooted my phone so that I can utilise it with a new Appradio2. It was running fine until yesterday when phone calls and texts stopped working all together, though data still works fine.
The phone occasionally pops up with an 'MM #6' error which appears to be caused then the phone IMEI has been locked out. I have been in contact with my phone provider (Giff-Gaff) and they have stated the phone isn't locked out.
My phone details are:
* Model no: C6603
* Android Version 4.1.2
* Baseband version 9x15A-ACEFWMAZQ-30110017-11
* Kernel version 3.4.0-g298631f-02021-gc1b7814
* Build number 10.1.A.1.434
The rooted apps I have been playing with are GMG Gesture, Greenify and Pimp My Rom.
I believe I was playing with Pimp My Rom before the issues were caused but I cannot remember what I changed. I also backed the phone up with Titanium Backup before the problem started and restored that backup yet it has not rectified the problem.
My last restort, unless anyone knows how I could resolve this is to return it to it's pre-rooted state and start again.
Any help would be grately appreciated.

where did you buy the phone? if you buy it from a shady dealer they might have report it stolen and tell your celluar service to block the IMEI...I know this happen alot on GS3 forums or check to see if your IMEI has been deleted off your phone, flashing sometime does this too, again this is on GS3

I bought it direct from Amazon so I doubt that is the problem. Additionally I asked my Phone Network Providor and they said they can't see a problem with the IMEI.
Thanks for the reply.

Yes I typed in *#06# on my phone and checked my IMEI number appeared fine. I then sent that to GiffGaff (my mobile network provider) asking whether it had been blocked and they said it hadn't.

I'll try un-rooting it and see if that resolves the problem. If it doesn't then I'll return it to the supplier and get a replacement. That won't be such a bad thing as I have a little scratch on the screen anyway.
Thanks for the help
Dave

Just refresh Rom. That should solve your problem

Then as already advised reflash and start from scratch which is what you should just do in these situations because no one can help unless you can list exactly what you've done.

Just to update you all, I unrooted and reflashed the phone and the error remained. Since then I've been in contact with the phone supplier (AVTree LTD, via Amazon.co.uk) and they have stated that they have had several complaints regarding phones from the same supplier recently and have forwarded the information onto Suffolk Police to look into. They have also said that they will offer me a full refund and will cover the cost of returning the phone.
Looking on the bright side at least it appears that I didn't do anything to kill the phone. I have also ordered a new one that is now £60 cheaper than the price I bought the last one for.
Thanks for all your help.

[Q] C6903 weird SIM / network error (with really bad timing)

Hi you all! Please help a girl in trouble!
Some time ago I flashed 3SE rom (1276-2189_14.5.A.0.242_R1D) on my phone because ..well.. the Nordic combined lollipop update took ages and I didn't wanna wait no longer.
The flashing went well and the phone worked properly. About one month ago the usb-cover came off so I sent it to get repaired.
Yesterday I finally got my phone back after three weeks and was such a happy girl. I flashed the customized NCB (1276-9897 14.5.A.0.270_R1D) to get rid of the 3-logo when booting. Then I moved all my photos n stuff on the phone... and first after this I inserted the SIM-card - only to notice that the phone does not work.
It won't connect to network. Says stuff like "invalid card", "emergency calls only". Everything else seems to be OK. I have tried a couple of SIM-cards that work in other phones, but nothing. The cards are not home cut, they are original micro sims. I took the sim lock off also, but it does not help.
I have tried flashing several roms, but still the same. I noticed that on some it get's some kind of signal strength, but on some roms it's just 0. I've flashed with flashtool and used also Sony PC Companion. But still the problem remains.
The IMEI can still be seen. On the phones package is the text SI 1276-2949.11 (FI, DA, IS, SV, NO). The phone is less than one year old.
Before everything got wrong the bootloader was unlocked. I checked with Flashtool to unlock bootloader and it showed the IMEI and redirected me to Sony's site, but I got a bit scared if some quarantee would get void. I don't remember the BLU redirecting me before to Sony's site if I have fiddled around with the phone and Flashtool..? The phone is unrooted and I would want to keep it that way. [Edit: it says "Rooting status: Bootloader unlock allowed: Yes"]
Now I am only very confused, and very stuck.
One thing that makes this crappier is that I am leaving tomorrow for my vacation, a trip that will last over one month... I really need my Xperia Z1 working and with me (and I really should be packing etc. instead of googleing and trying to figure out wtf I've done this time.... Unfortunately I really need that phone with me ).
Can somebody help, does anyone have any ideas?

And of course I have also tried the SIM cards with some paper behind them so that they would fit tighter.
If I try to put the APN manually it says that "Access Point Name settings are not available for this user".
I just tried once again to fix the phone with PC Companion, no luck.

Hello!
I can't find much to do but try to downgrade to a previous working version that was on your phone, and completely wipe everything (with stuff backed up of course) and see if the sim works, then update using PCC.
That's all I can think of, good luck and have a nice trip!
Regards,
~J2C

Hi and Thanks for the hints!
The 3-version of Lollipop worked earlier, but not anymore. Unfortunately I think it is the only version I can find from those that has worked on the phone earlier. Can't seem to find the original anywhere. I have had some backups of the phones and firmwares, but my computers got messed up, so I've lost some of the roms (and of course I have tons of other stooopid backups and their backups )
I'm trying to downgrade to some 14.3. global thingie right now, but my hopes aren't too high since I've done this already few times.
And thanks! I am sure that one busted phone can't mess up my vacation even if it makes it much complicated (water resistant, good camera, gps and battery etc.) But hey, what the heck, it's summer and I'm off duty

At least they are proper phones that actually DO work.
It's a shame I don't have any of those good ones left.

No other ideas whatsoever? Anybody? Mumbo jumbo voodoo? Rain dance?

Can you see your imei in the service menu?

Yes, the IMEI is there.

Got it fixed in another country in three days!
The service company I used first had broken some chip on the phone... Won't be using their "services" anymore.

Glad you got it fixed.
So it was a broken chip? Or did the chip get damaged when the first company tried to fix this issue?
