I am on Vodafone and the signal strength is full but the bar is grey (used to be blue). When I attempt to make a call it says something like "Cannot connect to mobile network". I have tried factory reset twice, taking the battery out for over 10 minutes and rebooting, toggling airplane mode on and off many times but they all didn't work. Can anyone help? Thanks.
I'm on O2 and had the same problem I went to 02 and thay got me a new phone but I'm on contract so thay had to. Maybe you will be able to get a new phone if that's the problem
Good luck

Just found out that it is something to do with the IMEI number. I will have to somehow change it or do something else to fix it.

OK so I need some help . . . . . after flashing a new ROM/kernel, I noticed that my network service was insanely poor. I thought it had to do with the new ROM but now after I have tried every which way of flashing and reflashing, I still have the issue. I used Speedtest to see what kind of DL speeds I was getting and I am usually in double digit kbps, 114kbps is my top. My wifes Acclaim regularly gets 600+ to the same server. Does anyone have any suggestions of what I may have screwed up or how I can go about fixing it? Everything works fine in WiFi btw.
Thanks in advance.
Fixed: Somehow I managed to get knocked off my 3G service. Called USCC tech support and they were able to turn it back on for me.

Try updating your prl. Dial *228 when at home and not roaming. Follow the prompts and wait for it to update. Should help and really can't hurt.

Yeah I tried that. No dice. Thanks for your suggestion though.
Maybe it's a hardware issue?

Is it even possible to "break" something like this by flashing new roms or kernels? Everywhere I used to have 3G service I now just have 1x.

Yeahhh it puts the phone in emergency mode and does some voodoo magic. I've heard of multiple people doing it.

I called 911 and it didn't work. The 911 operator didn't have any ideas either.
Well it's starting to look like I should start think about buying a new phone. I have tried everything within my ability and nothing. In a last ditch effort, where could I find a flashable radio that I could use just to make sure it is installed correctly?

Try going back to 2.1 and see how the data is. I somehow got a new prl when I flashed aosp and my girlfriends phone is on an earlier version. We both did the *228 and hers stays at 15108 mine stays at 15110. There is supposed to be a way to manually update our roll back prl. Idk wish I did

I did flash back to 2.1 and the data issues remain. The PRL on my phone and my wife's Acclaim are both 15110, but she gets 3G service and I don't. It also takes over a minute for my 1x service to load after turning off wifi. Also, If I force EVDO, I will get a "3G" banner at the top of the screen, but data does not work and the banner eventually goes away.
Additionally, is it normal to get a Verizon voice when you *228 while roaming? Because that is what I got when I was roaming yesterday. I have to believe that flashing Fascinate software has something to with it.
You could check the efs clear box in odin. I know it has something to do with service. I did that once in my vibrant by mistake. Are you dialing 911 in your home area? It needs to be in a uscc home area same with *228. The efs clear might break your phone worse so.......

Yes, which is why I said do it while NOT roaming. If you completed the *228 while roaming on Verizon you basically connected your phone to their network not USCC's.

I did the *228 at home while not roaming. When I got the Verizon thing while roaming I just hung up I never went through any kind of programming. This was well after things went awry anyways.
I believe this all started a few days ago when I tried flashing the ComaVolt kernel. I got a boot loop and had to do a battery pull. I then flashed dfgas's superclean port and I thought everything was working fine until I got out of wifi the next day and noticed my network service was aweful.
Go back to di14 and do the *228 and dial 911

Do you have a belief plan? If so flash it to stock with odin and take the phone in and tell them to give you a new one. Even if you don't have a belief plan I would flash it ti stock and take it in telling them it's defective. worth a shot. Sorry that nothing is working for you bud.

I do have a belief plan but I bought the phone on Ebay a few months back. I was just out for a bit and the banner at the top would go into "3G" but while it was like that I had no network connection. Somehow I pooched my 3G radio I guess. Maybe I'll call tech support and see if they can help. Everyone I have ever talked to over there has been really good so maybe it's worth a try.
so today when i got home from school i didnt have any bars, my sim cards in i took it out and put it back in and nothings happened.
i even flashed a new rom :/ nothing happened though
please help! i dont wanna send my baby to the phone graveyard </3
please help! D:

its not the sim card.
Settings/Wireless and Network/Mobile network settings
Make sure that Use Packet Data and Data Roaming are checked.
if still no signal:
Use GTG's back to stock, if still no signal, bad sim or bad phone.
I can't seem to get any service from my carrier. The phone can get reception/signal, it's just the phone displays No Service from the pull down notifications. And when I go into mobile settings and try to search for a network or anything, It says "Error while searching for networks." Is this the antenna problem? Would I have to open up the phone and adjust something? btw does anyone know where the antenna is located at?

I unlocked the sidekick, tried a ATT simcard got good reception like Tmobile, but still no service. Do you know where the antenna is in the sidekick?
Its probally an antena prob because surprisingly I droped my old samsung gravity smart in water by accident and my first thought was to take the battery out and let it dry,that succeeded on letting me turn it on fully but I had no reception what so ever which is odd but this sounds off topic a lil but I ended up bricking it o.o normaly t-mobile themselfs sometimes making horrible phones don't get me wrong their good but most of them are 2.2 froyo ._.

Cheers, but ive tried that and there is no option to enter the code, as now it tried to do it automatically, or get you to request a phone call and listen for the number.
was thinking of maybe trying to install a really old version of whatsapp, any idea where i could find an apk?

No, that doesn't work, just wait out the 5 mins and then it will offer you to either call you or enter the code.
I just got my phone back from mobiletechvideos JTAG service. Since then, my phone struggles to hold WiFi and 3g. It very rarely pulls 4g. I have tried a factory reset. Also restored my IMEI backup just in case. I have an extra micro sim arriving today. I'm just wondering if I could be missing something simple or is my phone royally screwed?

Sounds like your radio.
They probably updated your baseband to MF1, I'd try to use mb1 firmware to see if that fixes your reception problem.

Thanks for the fast response! I flashed the MB1 firmware and still have poor signal. I'm starting to get depressed as this went from the best phone I've ever owned to the worst.

I did take the phone apart and found that the WiFi connection was loose. I corrected that. I started the phone back up and held the Sim card down in the slot while booting and the phone miraculously got 41asu.....for about 5 minutes and now its holding at a steady 2asu. So, would there definitely be something wrong with the Sim card? Or could the Sim port be going as well? Is there a way to test the Sim connectivity in the phone settings?

The lower the asu the better, in contrast to a higher dbm is a better signal.
2 asu is a pretty strong signal, you should be around -80 dbm.
Edit; Nevermind I mixed it up, a higher asu is better. I still think it's radio related though, but changing your sim card is an easy potential fix.

Well....sim card didn't work. Next I'm going to Odin back to pure stock and see if that helps. I'm starting to think it may be something in the NV items or hardware related. Hope I'm wrong though.

Hi David,
Often times when devices become bricked, it results in your NV items being damaged and causes this problem. Here is a guide that highlights this issue, and will tell you how to remedy the situation.
http://rootzwiki.com/topic/32397-tutorial-imei-backup-nv-with-qpst-us-variants/"
ugh. I really dont want to go messing around with the NV items if that is the case. Im in the process of flashing with ODIN now. I'll update if that works or not.
What is your IEM Showing?
If its been erased, then ODIN to stock firmware probably won;t fix that,
but, have you check your mobile network setting to see if you are on the correct network?
If you are with Verizon it should be set to CDMA, not GSM.

Software is not intermittent. Hardware can be. You may have a broken or loose antenna cable or connector inside the phone.

Hi David,
I'm glad to hear you resolved this issue. This is quite surprising as the S3 is relatively easy to work on internally and we had never had this issue after working on one. I'll take note of this in case it's ever observed in the future. In the mean time, anyone ever having a questions regarding their order, just call us at 657-444-JTAG. Rock on buddy!
