My Artemis doesn't connect to the network anymore!

Suddenly my HTC P3300 doesn't connect to the Orange network.
I had the phone for over a month and now doesn't work anymore.
I have an italian SIM card and it works perfectly.
If I choose the automatic connection, the device keep searching forever, if I choose the manual, can't connect.
Not sure what happen here, Any ideas?
I'v tried soft, hard reset upload a new ROM, nothing!

Sounds more like a service provider issue than a phone issue.
Put the original ROM back in and then go to the nearest Orange store and tell them the problem.

I thought the same, but I think that there is something wrong with the actual device... If I try to choose any other available network that is not Tmobile, doesn't work..

Where did you buy your phone from?
It was a brand new? or 2nd hand

did U upload a pdamobizROM? If yes did U tried to restore anything from any bkup(sunnysoft, sprite, spb ....)I mean ie contacts or appointments ...?
If yes try other rom i found this prob with this rom. after restoring any bkup, it stops to connect to network(phone at least)

Yups same problem i have encountered with PDAMozbiz 1.1.2 ROM and am seeking help ..... is there anyone who can dedicate some of his precious time to help me out on this?

[Q] HELP! GS not conneting to network

I flashed JG5 using Odin (removed sim and sd card) after that i did the modaco r3. Now it does not connect to the mobile network. PLEASE HELP

Did you flash all three files (pda,phone and csc)?
Also, are you talking about mobile network for calls/texts or data only?

Thank you for responding.
Yes i flashed all together.
My Calls / Text is not working...the status bar does not show the connection.
I thought the problem was with the task killer hence that too has been un installed.
I did notice that when i switched sim cards and restarted the network came on but the phone would restart and the network would disappear.

did you install the apn files for your phone .most of the time you find a list at the provider .you can go to apps settings wireless internet mobile networks names and intrance points tip at tapp and tip on new apn .but first find your providers list .if you google apn list ore so you can find it also

Thanks for the reply. Isnt APN used primarily to connect to EDGE / GPRS. Is it required for registering on a mobile network because as of now the phone is not registering on the mobile network.

Need help urgently...hence bumping

Set up your apn again. Trust me

APN---Done that it did not help.
Sometimes i get the signal strength bars but when i dial a number it does not connect it just says Dialing.
This is getting very frustrating.
should i try to flash another firmware...if so please point me to a mirror site as the samsung firmware site is down since the past few days.

Yes, you probably should try a different firmware. Try JM2 from my mirror. (see signature, download is fastest if you run wuala. direct http downloads may be slow at times)

Thanks for the reply...Downloading JM2 in progress from your site.
One doubt...are firmwares region specific or anything goes ??
Once i flash i will update this post and i pray that it works

The content of the f/ws is region specific (additional languages and apps that only work in some countries). However, they all work on the your device!

Flashed JM2...same problem HELP!!

Should i format my internal if that is what is causing the problem...because i am not able to figure out the exact problem.

I have the same problem. I bought my GS from USA and I try to use it in Europe. I flashed it both European and America firmwares but I couldn't solve the problem.
When I press *#1234#, it shows that "Phone: Unknown" and *#06# responses nothing.

When i insert the sim card of another operator the phone works. My original operators sim works on other mobiles except this galaxy s. Any tips on why or how to check.

I'm having the same problem, any help to fix this would me really great!

It seems that the galaxy s is not connecting on 1800mhz after flashing. It connects on networks using 900 mhz. Any way to check this on the phone

This is weird. I tried using the phone from another location and it worked. I think this has to do something with the cell tower near my home location.

Hi guys,
I was able to re-flash the original firmware and all works again. If you guys want to go that way here is the link http://forum.xda-developers.com/showthread.php?t=734475 I think this is just for the Vibrant but I'm sure you can find the other firmware on the forums.

Cannot Connect to Mobile Data

Good day Gentlemen and Ladies,
So, as you the title states I cannot connect to mobile data (3g). (Before posting this I had done my research trying to find a solution and I cannot find any solutions) Let me tell you a little bit about my Galaxy Nexus SO originally when it was purchased it was a yakjuxw and I flashed to stock yakju-4.0.4 by this methodI can not link the video atm as I am a noob here) (I am sure that I did not skip any steps). I updated to android 4.2.1 all OTA updates and since that day I cannot connect to mobile data. I am pretty sure this is a software issue unless its a coincidence that my device fails on me at this point in time. Everything worked fine before i flashed it. I have tried going into *#*#4636#*#* and making sure my network type is correct as well as the radio band as automatic. I tried rebooting the device, I turned on mobile data and waited for +2hours for it to connect and nothing. I am sure I did not reach my mobile data limit as it is the beginning of my billing cycle. So, if anyone has any solutions would you be kind enough to give me a link or instructions on how to fix this problem. I recently also got double my data free of charge (from my provider) and I can't even use it Lol... Thanks!

1. Settings -> About Phone -> See your baseband? Does it exist or does it say Unknown?
2. Attempted to reset APN?
3. Tried your SIM card in another phone? Does data work on that phone?

Man you are a genius thank you. It was an APN problem. I think when I flashed it the server # and port # went missing or something so I added those and 30 seconds later it is all working! Thanks again my friend. And for anyone who has this in the future you can access you APN settings->more...->mobile networks->Access Point Names (and APN vary on provider)

data not working on stock rom but on flyme

Hello all,
I am from Austria and i have a bob-sim-card. It works with the A1-net. So i have to activate data-roaming.
As you see in the title, i have a problem with data connection. It couldn´t be solved with the technical support too, so i ask here for help, because i love my elephone!
I tried flyme and evereything worked fine, but i have all my contacts and apps backup on google, so i can´t use flyme. I went back to stock rom and the same again, data doesn´t work. It shows "U" or "3G" or "H+" in the display and the technical support also see connection, but firefox, wheather app, play store, .... can´t get data.
Does anybody has an idea???
Thanks and greetings from Austria,
Matthias

Try the following:
Go to Settings
select Data Usage
select your Carrier
Activate Cellular Data
Had the same problem (Phone showed 3G but there was no data connection) and this wasn't activated.

Thank you for the tip, it was off! But it doesnt work, with reboot too. I will make a few experiments more with these settings, its a little bit complicated to change sim for looking at xda.
Thanks and please for more ideas,
Matthias

I'v gone to Engineer Mode with *#*#3646633#*#*. CDS-Information says:
Network Information List:
(0)MOBILE()
state DISCONNECTED/DISCONNECTED
reason: (unspecified)
extra: (none)
roaming: false
failover: false
isAvailable: true
isConnectedToProvisioningNetwork: false)
Can anybody read this information? Data-roaming is "on".
There are a few more connections as mms, wifi,... This is the one that don't work i think.
Greetings, Matthias

huh, strange problem you have there - if you really do have to go back to flyme you can flash gapps for lollipop(around 200mb mini version) or whichever gapps package suits you. I did this and it worked fine, also installed nova launcher as hated the miui launcher!
your problem does seem to to do with the data roaming but unfortunately I'm not sure how to force this setting on...

Hello back again,
So there is a solution with installing gapps separat. Thanks for that!
I think the first custom roms are coming soon, perhaps cyanogenmod or something other? This would be wonderful!
P. S. I destroyed my imei with flashing, have to repair, perhaps it changes data-connection too?
Matthias

Not sure about the imei but I suppose it's possible, maybe have to try flyme again then! Hope CM put a rom out for us soon.

I did it!
Hello all,
the phone is working well now! Thanks for all helpers, there were two problems, here are the solutions:
1) When flashing the latest stock rom imei is destroyed. You can solve this with "MTK Engineering Mode" from playstore.
You open the app and go to: MTK Settings, Connectivity, CDS Information, Radio Information, Phone 1.
Here you have at the top "AT+". here you complete to >>AT+EGMR=1,7,"123456789012345"<<, of course with your imei, which ist standing on the akku-cover.
Then, very important: You have to put in a space after "AT+", so it looks like >>AT+ EGMR=1,7,"123456789012345"<<
Click "SEND AT COMMAND". Thats it.
For the second imei do the same with >>AT+ EGMR=1,10,"123456789012345"<<
2) The second thing is that you have to turn on data roaming at two places.
Settings, Data usage, Card 1, Cellular data and
Settings, More, Cellular networks, Data roaming
So, i hope to help at these problems, i´m very glad with this phone now although i have a few more grey hairs.
Greetings, Matthias

Glad you got it working again and thanks for posting the guide from the bbs forum here though strangely my imei has survived through at least half a dozen flashes(probably more actually!) but I may need this recovery solution one day when more roms come out.

change imei
Perhaps a mod can change the title to "change imei" or something similar?
Matthias

Data working
Not sure if this was mentioned but people who have problem with data network 3G etc I seem to found a solution.
Simpler that it seems. You just need to set up a APN in you settings. Never had to do that with my previous phone (Galaxy S3) so it was a surprise for me.
You just need to find the settings from your provider (they usually have it at their website) and then you should be fine.

No the imei is not destroyed per default by flashing, it might be destroyed by a faulty flash.
I flashed mine a couple of times now without any problems
And no, you don't need Data Roaming on (unless you are roaming).
Cellular data need to be turned on though as it's off by default after flashing.
Just to make things clear

Thanks sharkware, i flashed with sp-flashtool on Win7. Good for you when your imei is ok. Mine was not, no problem.
I have to activate data-roaming because i use a provider who has no own net but works together with a big provider.
Thanks for your comment, i see clearer now.

No signal, no wifi, no gps

Hello you guys!
I just received my lg g7 g710ulm. And when i turned on the phone i understood that im not lucky.. I need your helps! Please! Because i cant do it myself.
1. No signal. Don't search networks. Immediately getting error when trying to do it myself. "Preferred network mode" can't change due error and it showed "null". After reflashing it's now showing "22".
2. Don't see any wifi networks. But access point is working and other devices can see me.
2.1 I found that wifi going to work then i tried to use gps. After few seconds phone starting see wifi networks and connecting. If turn off wifi and turn on again phone don't see networks and you need to repeat procedure.
3. Looks like gps not working too.. But tried only in indoor.
I can't understand is it software or hardware issue. Maybe seller changed imei number and model by firmware and did it wrong? Antutu showing strange imei.
Can i to know somehow real model of phone? I can try to make logs and attached it here. Or maybe somebode can check imei, bands with octopus box? I dont know what to do
P.S. Bluetooth is working. Tried to send file and it was fine.
I can't return phone to shop because im living in different country But phone is amazing! And I loved lg. I had lg optimus one (was lost and back by good people), then lg optimus black(was burned in bonfire), lg g2(left in taxi), lg g6 (was lost) and finally lg g7. Yeah, looks like something wrong with me or these lg.. But i love it

Did you put in your SIM card first before you started...
I read you need to insert sim first but could be wrong.

Sure, i did it. Anyway don't search networks. But what carrier of sim card and numbers into sim card, phone can recognise.
Maybe i wrote not understandable? My english not first language. So asking. I will try to explain.
Thanks for your reply.
I uploaded a log file with errors but cant to write here link, because i need 10 messages

My G710ULM's GPS stopped working 2 days ago, still trying to find out what's the cause of it. Tried apps like GPS Status, GPS Locker, no avail that it isn't picking any satellites at all. Just searching for GPS location. Restarting the device haven't helped either. In settings I even excluded all apps in Power Saving Exclusions. In GPS Status app, resetted and downloaded the A-GPS, this should surely make the GPS work. No success.

Hello expert. I have an LG G7 ThinQ ULM phone. The problem of this phone is no phone waves signal, 3G, 4G. (a week ago that is good). I think that because the SIM and insert this SIM into other phones, this SIM still works very well. So can you show me how to fix it? Thank you very much!
Note: I was try as below but not success
Go to the Home screen;
Tap on the Phone app;
Switch to the Dial pad;
Type in (*#*#4636#*#*) and just wait – the phone should automatically redirect you to the Service mode;
Once you’ve entered this new mode, tap on Phone Information or Device Information;
Tap on Run Ping test;
Look for the button labeled as Turn Radio Off and select it;
Wait for the phone to restart;
Tap on reboot.

hi, i need help, same mistake, i dont get a solution

Hi guys, I bring a solution to this problem, I found this topic: https://forum.xda-developers.com/t/no-signal-after-crossflashing.4089281/, you understood better by reading yourselves, but basically I flashed the rom with lg up chip erase mode and my wifi/data started working again, I know this is not recommended under any circumstances but it worked for me.

However, be aware that ChipErase mode not only erases IMEI numbers, but also erases MAC addresses, EFS partition and others. In many countries if your device does not have an IMEI number or other identifiers, SIM networks cannot allow (my case in Brazil it worked) for you to register with them, i.e. in most cases your sim will not work on the phone and you will not have cell service. You may still have issues with WiFi networks as without MAC addresses your WiFi will be grayed out or the network may not allow you to connect. Also, be aware that in many countries around the world knowingly tampering with or changing your phone's IMEI numbers is against the law. IMEI number is how networks and ultimately law enforcement identify the device and its owner
