You shouldn't have used that dailer code to "upgrade " that only works for the phone when it is on the Sprint network and its known to take away the unlock. You have to unlock the phone again in order the activate it on your GSM network

XDA Orbit unable to find network - HELP

Hi,
I have an XDA Orbit. Everything works ok except when I try to use the phone, It searches but cannot find a network. The inserted SIM is o2 Pay&Go. It does ask for my pin on startup and can read the SIM history but when I try to call, the calls ends after about 2 seconds and it comes up with the following error message:
"Cannot complete the call. The signal may be unavailable or the phone number may be invalid. Verify the number and try again later"
The SIM is ok as I have used it in another phone.
Any suggestions guys...
Regards
Brian
is the phone blocked by o2? if not try flashing an official o2 rom
Not sure if it is locked to o2, I have tried the o2 SIM and a T-Mobile SIM but both give the same result, unable to find network.
I have flashed it with the official o2 WM5 rom and the WM6 upgrade and I ahve tried a different radio firmware but same result...
I would welcome any further suggestions.....
Try engineering mode with GSM reset
Hi,
Thanks, I have experience of successfully flashing the orbit but "engineering mode with GSM reset". Some help please as to how I do that.

[Q] Galaxy note 3 Bricking problem

Appologise me for my english, i'm from Romania; i've got an note 3 and i changed his firmware ( with Odin) with an original one from Hungary(the phone was bought from Orange Romania) with Android 4.4 and than i rooted it. After that i found that i have some problems with signal and i changed his firmware again with an Romanian one from Cosmote because this one was not branded too. After i 've changed it for the second time i found some problems too and i decided to try to put the original firmware from Orange Romania and i received an erorr in the download screen"SW REV CHECK FAIL : Fused 1 > Binary 0"and the screen change into "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again."
I tried to conect with Kies but the program tells me that the device is not compatible(tried with Kies 3).
Can you please help me, i don't know what to do.
Are you trying to flash back Android 4.3? If yes, it's not possible at the moment to go back to 4.3 if you flashed Android 4.4.

If you are trying to downgrade from 4.4 to 4.3, don't even bother as bootloader would stop it from downgrading. Hence, softbricking the phone...

[Q] How should I proceed to unlock SIM network on my I9300?

Hello,
I have an I9300 under the latest Omnirom nightly
I got the unlock code from my mobile operator/ So when I insert a foreign SIM, it requires me to fill it, which I do, but it returns an error saying that the network unlocking was unsuccessful.
I've tryed using dial codes like:
#7465625*638*XXXXXXXX# (XXXXXXXX being the actual code) to unlock SIM network, but it says "Connection issue or invalide HMI code
*#*#197328640#*#* to run service menu and get to the network lock menu, but it says that "MENU NOT EXIST PRESS BACK KEY Current Command is 186"
I've also tryed using GalaxSim Unlock application but it 's unable to actually unlock my phone because it says the blocking system is not yet supported.
I'm running out of ideas to unlock SIM network on my phone, so any help is appreciated, thanks in advance!

You probably have to be on the stock ROM to unlock.
