this means that your device is sim unlocked .. no need to use the code
you only use it if you insert a sim from another company and THEN it will ask you for the code

this when the code comes in handy , you should enter the code then.
where did you get this code from ?
i am not sure about this .but. if you tried unlocking it with any other software like lokiwiz then "maybe" you should hard reset your device before trying again .

I never said tap on the emergency . you are going to get yourself into trouble man .. really calling 911 to unlock your device ..
the steps are
1- turn off device .
2- put "another" sim from "another" compay"
3- turn on the device
4- enter you unlock code in the "TEXT box" -i missed the t before the ext sorry-
5-press ok
if the code is not right you will get an "invalid code " message
where did you get your code from ?

Thank you for your big help
sorry to bother you. probably I'm getting yourself into trouble...
I got a code from tupisdin, then,
I enter the code into text box for emergency number,
but OK was not appeared, just emergecy button is dimmed.
Just in case, write under what I did.
1- turn off device .
2- put "another" sim from "another" compay"
3- turn on the device (of course, I'm sure that it is not fright mode)
4- wait for a while, then it was displaied TEXT box under "SIM Lock, You can still make emergency calls if your service..."
5- enter unlock unlock code in the "TEXT box"
6- keep to dim "Emergency" button...
I probably mistook right?

Rogers (CANADA) Messaging Center Number

Let me guess...
You've discovered some hidden menus recently by typing codes in the dialer and find out this one: *#*#4636#*#* that open a "Testing" screen showing options like this:
Phone Information
Battery Information
Usage Statistics
Wi-Fi Information
Then you went to Phone Information
Tried some options (maybe played with SMSC:_________Update / Refresh ) but that was not doing anything so you exited the menu.....
after a while you wanted to send a text or someone was asking you "Did you got my text?" and you didn't....
Here's what hapened: Accidentaly you erased from your phone the "Messaging Center Number" wich is responsible for giving your phone the access to the SMS/MMS central of your provider.....resulting in loosing the ability to send/receive messages.
Don't worry, after having navigated XDA Forums I finally found my way to make it work again (yes that's because I did it that I now now it).
By the way, even if you Factory reset, flash a new rom/radio/kernel that mistake is gonna stay. You need to enter the number again.
in the *#*#4636#*#* hidden menu,
scroll down to "SMSC:"
in the box type: 0791715097960300
press the "Update" / "Mettre à Jour" (first button)
Now exit and Reboot the phone.
To test it, don't try to resend an old test message as it contain old message center number. I even suggest to delete previous text messages from your inbox if possible.
If it worked, everything should be fine by now. (you can even kudo me for this loll)
NOTE:
The real Roger Center number is +17057969300
the thing is that it need to be Encrypted in Hexadecimal PDU format.
(user MarcusVanSciver on XDA shown that link in thread http://forum.xda-developers.com/showthread.php?t=1412261)
That was for Orange Network (european have 8 number to phone number instead of 7 so I had to add a 0 at the end to make it work for Rogers)
after Encryption the number was now: 0791715097960300
This worked for ROGERS, the trick could maybe work for other networks but I can not validate the info. (but for sure this will not be the same number)
This had been tested with stock rom and Custom Rom With Custom Radio and Custom Kernel.
If this helped you, please give credit to this post ;-)

Easier way to do it without mucking around looking for your SMSC. It's how I got mine up and going again!

Hey man, this might be a bit old for you but i just got a galaxy nexus. I am having the outgoing text issue. I've tried that number and everytime i hit update it just says update error. Think you mightbe able to help me?

Damn this doesn't work for me

To program the SMSC (Text Messaging) number on Android devices, please follow these steps:
Go to the phone application.
From the phone application, press *#*#4636#*#*. (You will have to press the Call or Send button after entering this code in for some Android devices).
Tap on Phone Information
Scroll to the bottom to where it says SMSC and enter this number exactly as you see on this page (including all symbols): +17057969300
Press Update.

[Q] Anyone have 0/12 IMEI number but network semi work and EFS missing NV_data.bin

I installed the jedi mind trick JB6 rom a week ago and everything worked great up until a few days ago. Now my phone when connected to wifi can't access the play store, gmail and other apps. I can receive/make calls through wifi calling and texts just not internet data. As soon as i turn wifi off everything works normal. So I checked my Imei and it showing up as 0 / 12 . Anyone else experience this and is there a fix for it. I already tried restoring my EFS folder but the two needed files are not there and I never made a backup.

I have this phenomenon on my SGS2, and have had it such since January after flashing an Embryo ROM. I'm not sure how it happened, I used to think Embryo borked it but no other users reported anything similarly happening to them.
However, I have no issues with data or anything else problematic occurring as a result of the IMEI being 0'd. Everything works fine. I use Straight Talk, so I think IMEI blacklisting doesn't apply to me, but it may be a factor in your case, as ATT/T-Mobile are more stringent now about EFS tampering etc. because they now blacklist handsets.
QPST or somesuch, a Squidbox, or Riffboxing type of repairs may remedy the problem. Try using a different SIM for another network and verify it's not a carrier specific issue. Also, try going back to stock and doing an EFS restore via the Service Menu from stock Dialer. (*#*#197328640#*#*)
Also, to save any trouble; Odin will not help you, as the EFS partition is handled seperately unless you check the box to clear EFS...which will also not help you.

Just take a backup, hard reset your phone and again follow the steps. If it doesn't work, just try to update or change the ROM and try again. Hope this helps.

cant disable fast boot

hi everyone, i received today my phone, it seems to be a korean import unlocked for sims but not rooted.
i had a galsaxy s2 for a few years and know how to root and flash a rom, but problem is, on my htc one m8 there is no option to disable fast boot in the battery menu
i looked everywhere on the phone, it's just not there. i looked on the net and somebody suggested CleanFLASH 1.0 just to start the phone in hboot, but can't manage to find the file anymore, links are dead, any suggestion?
thanks

anybody can help with this? I'm bloody stuck without a rooted phone!!!! thank you

Is your main problem not being able to get into bootloader (I don't see how else the fast boot power option would prevent you from rooting)? Just hold the power button until the options come up, select Restart, then when the screen goes black, immediately (before the white HTC boot screen) hold the power down rocker, and don't let go until hboot appears.
Alternately, hold power and vol up to force a reboot of the phone, then when the screen goes dark, switch to holding the vol down rocker.

Why are you worry so much on "fast boot" ?
You don't necessarily need to press power + volume down to go to hboot/bootloader.
I never disable "fast boot". Just simply restart, wait for the downanimation complete (it turn black screen) then press volume down (no holding power button) ... it will go to hboot.
Or you can plug in your device to PC with USB debugging enabled. Open a command prompt from your adb folder, type command adb reboot bootloader

thank you. i've tried all the above all afternoon, including all the tools available but phone will only either reboot, sometimes in safe mode, or reboot regularly.
I think I know what I'm doing. I need to unlock bootloader to root, but this is not possible. When connecting to pc by usb, and using tools, from comand line, computer screen just hangs and nothing else happens. with another program I can only see a tiny "fast boot...." on the bottom left corner of the screen. I cannot basically unlock the bootloader hence root the device.
another few things i notice you may be able to double check.
trying to reboot in standard recovery, the android buddy comes up on the screen, like dead, with "no command" message. then pressing volume up will take to recovery screens, never seen this before.
And last, but not least, checking the serial number from the menu > about phone > status the serial number comes as
0123456789ABCDEF
I checked with HTC support on chat and they basically gave me the registered serial number for this IMEI and told me of course that it is impossible that it has another number as this cannot be changed.
Question is... Have I got a clone here??
edit: sorry about the data, it was not set the apn, now it works. normally used to have automatically apn from sim card, but it's not the case for this phone/sim

I bet you do have a clone, does the phone has a playstore ? Install some phone specs app and see what it comes up with.

it looks like that, checking the specs i can see a ARM v7 Processor, rev3 and a screen resolution of 1280 x 720...

Unfortunately, I think your device is a "Clone".

thanks guys, i've haven't been rooting for a couple of years, but really thougt something was wrong, terribly wrong. ok, will check back here when i get a real one, if needed.

I think he was talking about "Fast boot" option in battery settings and not the "Fastboot" everybody is talking about here. Nevermind. And yes, that phone is/was a clone

The subsequent responses by clpv5 and myself understood that he was talking about "Fast boot" in Settings.
The only reason the "old" root guides instructed to turn off "Fast boot" in power settings, is that this mode enabled would prevent you from entering bootloader from a "powered down" conditon (since with the "Fast boot" option enabled, the phone was never actually powered down, just a deep sleep mode).
But as we pointed out, you could always enter bootloader from a reboot, since a reboot is always a true reboot. This would work regardless of whether "Fast boot" was enabled or not in power settings.
Although it should be noted this thread is from July 2014, and the "Fast boot" option was removed some time ago.

Thanks. I was looking for an explanation like that; in fact, somehow that's why I ended up in this thread. Though, it's useful yet, since there must be lots of devices still running the 'Fast boot' option due to certain manufacturer's lack of firmware updates and because not every device in need for support out there is actually a new device

thank you. i've tried all the above all afternoon, including all the tools available but phone will only either reboot, sometimes in safe mode, or reboot regularly.
I think I know what I'm doing. I need to unlock bootloader to root, but this is not possible. When connecting to pc by usb, and using tools, from comand line, computer screen just hangs and nothing else happens. with another program I can only see a tiny "fast boot...." on the bottom left corner of the screen. I cannot basically unlock the bootloader hence root the device.
another few things i notice you may be able to double check.
trying to reboot in standard recovery, the android buddy comes up on the screen, like dead, with "no command" message. then pressing volume up will take to recovery screens, never seen this before.
And last, but not least, checking the serial number from the menu > about phone > status the serial number comes as
0123456789ABCDEF
I checked with HTC support on chat and they basically gave me the registered serial number for this IMEI and told me of course that it is impossible that it has another number as this cannot be changed.
Question is... Have I got a clone here??
edit: sorry about the data, it was not set the apn, now it works. normally used to have automatically apn from sim card, but it's not the case for this phone/sim

oh man, i thought i was the only one !
i have the same exact phone !
my serial number is exactly 123456789ABCDEF !!!
mine is a chinese mtk htc one m8. after hours of search i figured my phone name is alps_htc one m8 and yes my friend, is a fu..... clone !!!
i tried everything ! and search whole bunch of websites and forums like xda and xda itself, nothing happened !
i also get the => fastboot....... every time i try to go to bootloader !
this is something that you guys who trying to help here had to understand, these clone phones settings is completely different from other phones and even the original one ! hold power button then hold volume up or down, doesn't work !
every time it stock in => fastboot..... none of the buttons of the damn phone works and i have to wait until the battery drain ! real pain in the ass !!! because you know, htc one m8 does not have battery removing option, another pain in the ass !!!!!!!!!
i had a another problem too, when i wipe this clone phone, amazingly, the IMEI was gone !!! the phone said "invalid IMEI" !!! witch after hours of search i flashed it with an app from mobileuncle tools, thank to them amazing app allowed me to flash a custom IMEI from a unused phone.
now i use another htc device from the original manufacturer.
a little piece of advice, do not buy a clone phone ! cause it's going to piss you off !!!
and if you don't know how to recognize a clone from a original phone, its simple, just check the serial number, if it's feel weird, just give back the phone to seller, smile, and run out of the store !
thanks to XDA btw.

I've found a thread with the answer:
1. Disconnect USB cable from phone.
2. Go to Menu->Settings->Applications->Development.
3. Turn on "USB Debugging" option.
4. When message is appear press "Yes".
5. Go to dial window.
6. Enter "*#7284#" number.
7. Set "USB" radio button to "Modem" value.
8. Close window.
9. Go to dial window.
10. Enter "*#9090#" number.
11. Set "Diag config" to "USB" value.
12. Restart phone.
13. Then download EFS Professinal from http://forum.xda-developers.com/show....php?t=1308546
14. Extract and open efs professional and click on Qualcomm NV Tools
15. You must see your device in "Available COM Ports"
16. Now click on "connect", it will show "SPC was accepted by the phone".
17. Now just see the "IMEI Repair"column, it will show blank or '0'.
18. Now type your IMEI number infront of "IMEI" and click "Write IMEI".
19. Thats it.
