what rom are you using? what kernel? what were you doing before it stopped working?
why would you run custom operating system software on your phone if you aren't good at technical stuff? sounds like you are waiting for trouble and hoping someone else can fix it and read your mind because you are bad a explaining the technical stuff you dont understand??
heres how to fix....
flash to stock with odin one click .[Stock ROMs](OneClicks Master Collection)
LEAVE IT LIKE THAT.
DOWNLOAD INSTRUCTIONS:
-Perform a factory reset on your phone. (Optional, recommended)
-Download any OneClickOdin package to your desktop.

-Wait for Odin to recognize your device. Yellow com port will light up.
-Click the big Start Button.

hey..
i am using continuum v6.1.
and i was doing nothing..i jus got up today and the phone was not working ..

sounds really odd, did you flash a new kernel? anything different at all? Have you tried rebooting?

In the dialer type *#0011# then reply with what it says on the third line.

I've had this happen to me a number of times (more often then not when flashing a ROM or back to stock). In my experience this is b/c I've lost my APN. Anyway I check this first:
SETTINGS --> ABOUT PHONE --> STATUS --> MOBILE NETWORK STATE = Disconnected
Then I head over to here:
SETTINGS --> WIRELESS & NETWORK --> MOBILE NETWORKS --> ACCESS POINT NAMES --> Here you should get prompted to enter an APN, click yes and follow the prompts and enter one manually with these settings:
Name: AT&T
APN: wap.cingular
Proxy: leave blank
Port: leave blank
Username:[email protected]
Password:CINGULAR1
Server: leave blank
MMSC: http://mmsc.cingular.com
MMS Proxy: wireless.cingular.com
MMS Port: 80
MCC:310
MNC:410
APN Type: MMS and Internet
Auth Type: none
Save and then select it and you should then connect no reboot required (well for me at least). This is one reason I always install the app "APN backup and restore". Of course you'll need to connect to a wireless network in order to connect to the market, etc... so I find it faster to just add one manually.
Hope this helps.

WIFI connected but cannot go to INTERNET!!HELLPPZZZZ

my Wifi show that my diamond is connected with my router. however, when i use internet explorer try to accesss to google/yahoo, the following message pop up:
"The page cannot be found. Check the name and try again"
i have double check and i am sure i enter the right address www.google.com/www.yahoo.com
i dun understand why this message pop up even thought i have connected wid my router. i am upgraded my router firmware to the newest one!!!!!
Rouer type is : Netgear Rangemax
Channel: 6
Region: United States( i am living in Uk and the router do not let me change the region to UK)-(i dun think this is the problem as my Ipodtouch connect with my router and work perfectly)
Mode: B and G( i have downgrade from Auto 108mbps)
Security option: WPA-PSK [TKIP]
any1 plz kindly help me wht wrong wid the diamond or router---> the main reason i buy diamond is to connect wifi!! thank!!
Hi,
Try changing the default network for Internet connections...
Go to settings -> connections --> advance --> select networks --> Programs (...) Internet should connect using: My Work Network
Cheers,
David
Same Problem here.. i've just updated my diamond with the newest software release ( HTC_GER_2.03.407.2) from the HTC Website.
The Diamond detects the WLAN, and connects after entering the key.
But i think the main problem is that i cannot select anything under "connect with" when i'm in the network setup.. There's only a white box :-(
I attached a screenshot from an other user there it's ok..
In my case there's nothing to select under "Verbindet mit"

I experienced following :
If i set up the wlan connection directly after a hard reset it works !
The problem is the connection manager "Verbindungs-Setup" that starts automatically..
This first run autostart item asks for your network carrier.. after selecting and applying the selection this assistent overwrites the existing wlan bindings. After this no more binding to the wlan is possible.. And it don't works too if you first run the "Verbindungs-Setup" and then the WLAN Setup.. Even to create a connection manually with the "> connections --> advance --> select networks --> Programs (...) Internet should connect using: My Work Network" is not possible!
I stopped the assistend at first run and configured my MMS and UMTS setting manually.. WLAN works now!

You can make a backup of your ROM with SpriteBAckup, then HardReset and Restore the Backup with Merge Level 1 of Sprite Backup. The Internal strorage will not be deleted by a hard reset!
Comm Manager - seting - WIFI - 3-d page and slider to the left
The problem is in the ROM. I have this issue only if connecting to WiFi using WPA2-PSK (TKIP). All other protocols work. Upgrade your Diamond with any other ROM and it should work. I had problem with Dutty's v3.4 and also Nataly v2.0.1.

It is not the ROM issue.
I have the same problem. I updated the ROM, but the problem exists as before.
Sometimes my phone connects the internal modem and not my WiFi network, why?
Ps.: I am using WIFI router for internet (WPA-PSK [TKIP])

Help ! Can't activate...

Hi ya
Got my unlock code and it ulocked my G1 succesfully. But now i have some problems activating it . I press the "menu" button then went to "APN settings"
then i pressed again the "menu" button and did "new APN"
So there i'm lost. Cuz i have Cosmote (Cosmote is greek) and i don't know it's APNs..
Can anyone help me ???
What do i need to write ?
name =
APN =
Proxy =
Port=
username =
password =
server =
MMSC =
MMS proxy =
MMS port
MCC =
MNC =
APN type =
Thanks for the help
P.S BTW i don't have a Data plan does it mind ???
Not sure of your APN settings, but you can register over wifi. You will need to setup adb (The Android Debug Bridge), which is a very simple process, so have a look for a guide on that.
If you do find APN settings, it shouldn't matter that you don't have a data plan, they will most probably charge you as you use data. So it will work, but when your phone signs in syns it will probably use a couple of megs which you will get charged a lot for. On my pay and go plan they charge £3/mb :<
ok thanks for the help
Edit: god that's difficult any video tutorial or a tutorial with pics ?
It may look intimidating, but it really isn't hard.
Adb just involves extracting the sdk and installing a driver. Then to enable wifi copy and paste that command.
Here's a guide on setting up ADB
The only command you will need from that huge thread on enabling wifi is this:
Code:
am start -a android.intent.action.MAIN -n com.android.settings/.Settings

help apn not saving after reboot the galaxy tab

does anyone here know why everytime i reboot my tab my apn is not saved? i'm using the tab with simple mobile,but everytime i reboot it would put back the tmobile apn back on it even after i have saved the simple mobile apn.
I had that problem when I used JK1 firmware. I switched to a different firmware and have not had the problem again.

Add it to /etc/apns-conf.xml with geditor
You can always try deleting tmobiles apn. Very easy to put back on, just hit menu and restore settings and it adds it back.

You'll have to manually flash another ROM. I switched to JJ4 after having the same problem and it stays after reboot now everytime!
A wipe/factory reset would be an option, however you could do this as well - Connect via WiFi, go to Market search and install APN Manager..you can set your apn there..it works for me!

You need a HyperTerminal or other Terminal app that can connect to modem on COM port and run AT commands.
1. Connect phone by USB (phone should be on normally)
2. Enter 3845#*970# in dialer
3. Select Port Settings -> Select CP USB
4. Start hyperterminal, in COM settings select same port like in devide manager -> LGE mobile USB Serial Port, 115200bps
5. Type AT if response is not OK, change port number
6. Type at%imei, it should display your current IMEI
7. Type at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x , where x,x,x... is your orginal IMEI number
8. Change again from CP USB -> AP USB
8. Restart
You should know that in many countries changing IMEI is illegal!
How did your reply Thanks...

i cant do it coz i recieved unknown device alert when selected CP USB
i recieve error when pressing enter after typing the right IMEI.
What should i do?

Thanks
p.s. i used "tutty" instead of "hyperterminal" cause of windows 7
i cant do it ....coz when i go to ur 2nd step ....it says coonection problem or invalid MMI code
P.S my IMEI is not displaying after flashing CM7 ...and i seriously want it back :|
Help rebuild imei after smartflesh tool. Now installed Zeus 2.2 + Hidden menu pack. In "Port settings" i have only three points: "Diag setting" "USB Switching" "Data Setting". "Select CP USB" - I do not have.

update: Found a shift in the "AP CP USB Switchings". Now another problem, I do not see the printed text in HyperTerminal. If i tape "at" blind to dial and press enter, see the corresponding OK.

In the blind well replaced. Thank you.
This was successful as if by magic!
Was really helpful, thank you.

I have the same exact problem and don't know what to do about it. I don't think you can get root as that's not really a terminal??
EDIT: i just got it to work. 2 things I did differently 1) turned off airplane mode. 2) didn't change the baud rate setting to match the one in the lg mobile modem details. probably airplane mode was the problem though . Also, I used the commas, but not one at the end.

i have t-mobile g2x (aka p999dw). i followed all steps. For access to hidden menu i typed "1809#*999" (coz my device is 999dw. It appeared and i tapped to port settings. I also checked "retain cp usb after reboot" and phone rebooted. i chose correct port. and in putty i checked "serial" section, then typed comx (which my own), baud rate 115200. Everything fine. When i hit the Enter putty pops-up a window but nothing respond.

not registered on network

Hi
I have recently updated the firmware on my n7000 from 2.3.6 to 4.0.4 and ever since I have not been able to make calls or go on internet
Network - unknown
Service state - Out of service
Mobile network state - Disconnected
Next to my battery icon top right of my phone I do have 4 signal bars which change from time to time displaying 2 or 3 or 4
the MD5's I have tried using ODIN are
N7000XXLRI_N7000OXXLP8_N7000XXLRB_HOME.tar.md5
N7000XXLRG_N7000DBTLRG_N7000XXLRB_HOME.tar.md5
Vodafone have confirmed it is NOT blocked by IMEI
What can I do to determine if it is infact blocked by EMEI
Thanks

you can check your emei, in your phone, settings, about phone, then status. Is it the same as when you bought phone?
you can check your apn settings, are they as provider prescribes?
When reboot does your phone ask for sim pin?

nope if phone doesnt ask you to authenticate sim pin, then it wont register on network.

I found the apn settings and enabled use packet data, data roaming, clicked on access point names and ha 1 listed which is 3 so i selected that
network mode is set to gsm\wcdma auto mode
network operators.........searching........for ages!! then i get
3
3
vodafone uk
02 - uk
t-mobile uk
clicking on either of the 3 networks says........unable to connect try again later
switch data roaming off, youbmight get extra costs. Apnbsettings should match your providers.
If lances method didnt work after reboot, see post above, delete apn, reboot, register on your mobile network, check apn with providers, or have provider resend it. Some times you can do this yourself from providers website

i have to be rooted to follow this, wat is quickest method i dont have a sd card installed
- Download "Terminal Emulator" app from market
- open it
- type into the command:
su
echo -n ON > /efs/imei/keystr
sync
Go to home, force close your terminal app, shut your screen off, and when your turn it back on your lock screen should be there.
Obviously you must be rooted the "su" command.
can someone pliz elaborate on typing su into the command
i have /$ when i type su it shows
/$su
The selected command does not exist
just download the one with busybox and try to install it from stock recovery http://forum.xda-developers.com/showthread.php?t=1841288
use update zip option and save it on internal sd Should be pickable.
Remember your on unsafe kernel, dont wipe factory reset at all.
Getting into recovery is tricky: switch off phone, immediately
volume up, home button and power button at the same time keep pressed and after reboot its in recovery mode. Navigate with volume buttons and confirm selection with power button

Downloaded it and installed as you said
The program Terminal Deluxe tells me that it has been granted super user permission when I start it
But it still says...
/$su
The Selected command does not exist
I am simply typing the first line "su" straight after the "/$"
Is this correct?
Just to add more info
I put a Vodafone SIM into this phone and it got an E data connection but no calls
Whereas when I put my 3 SIM card in I get no data or calls
Does this give any clues????
press 'enter' on your Note's keyboard... Everytime you type something on the Terminal Emulator app, you have to press enter after.. (just like what you would normally do on Windows Command prompt (DOS) mode option.

I dont have an ENTER key on my note keyboard, I do have a DONE button which is what I am pressing
if pressing DONE accomplishes the same process of executing the command 'SU' then that's all good still.
So where you able to execute the other command after 'su'?
