Change ur imei by this method
1- go to em with this code "* # * # 3646633 # * # *" (just type it on call pad)
2- then follow that path --> CDS info --> Radio info --> Phone1 (for the first imei)
3- at the top there is a command line which begins "AT+" just type there "AT +EGMR=1,7,"IMEI_1" (instead of IMEI_1 put your first imei number)
4- hit send command
5-if you done just reboot the phone, if you change the second imei go to step 2 and select "Phone2"
6-and enter the code "AT +EGMR=1,10,"IMEI_2" (instead of IMEI_2 put your second imei number) hit send command
7-reboot
This will work I have checked thanks for original poster
Sure, this will work?
And by entering/changing this IMEI there won't be any problem at all?
And also please send me a link for its firmware also.
If any newer version is available, will be better choice.
Thanks a lot for your help

Hello everyone,
I have a Samsung SGH- T839 Sidekick, Android 2.2 Froyo OS stuck on T -Mobile USA, I am trying to unlock. I followed the instructions in this forum: " http://forum.xda-developers.com/showthread.php?t=1110263 " .
I think I have managed to unlock since I managed to get the unlocking code in question and to inform . Besides, the message " Network Unlock Successful" appeared on my screen, more and inserting the code " * # 7465625 # ( View Phone Lock Status) " , the " Network Lock" is off.
My problem is that my phone still does not recognize my SIM card ( that of a Méditel Moroccan operator ) and by going to: Settings- > Wireless and network- > Mobile Network , I still have a window under the name "Insert SIM CARD " with the following message : "Insert SIM card to access network services ." Knowing that at any moment I was prompted to enter my PIN.
What to do? Could you help me please ?
Thanking you in advance,
Samsung Sidekick SGH-T839 Unlocking problem
Any suggestions please?
You might be able to request a SIM unlock code from T-Mobile; see http://www.t-mobile.com/Company/CompanyInfo.aspx?tp=Abt_Tab_CompanySimUnlockPolicy. Or maybe try one of the many SIM unlock services available on the Internet; just be careful, because some of them are scams.
I don't understand
Hello,
I don't understant why I should find a new code if, like I said, The Network Lock Status is off?
( " * # 7465625 # ( View Phone Lock Status) " , the " Network Lock" is off. )
device : Advan Vandroid S4K (a.k.a Star Mini)
OS : 4.4.2
Processor : Spreadtrum sc7731 (sc8831 if use MTK Droid Tools)
Status : Rooted
I just rooted my phone with KingRoot and installed Xposed because I want change status bar style with Flat Style Bar Indicators, after that I continue browse modules and saw Lollipop Navigation Bar and install it, active it and reboot. I don't see the changes and open it for more help, I see tutorial there (paste this command below in build.prop), do it quickly, reboot. after that my device was bootloop. OMG
Googling for help and I found how to revive my device (I forgot the URL), it tells me connect device to PC and open command adb:
adb reboot-bootloader
In fastboot mode, write command:
fastboot -w
then disconnect device and flash stock rom with ResearchDownload, 5 minutes later my device alive again.
After flashing stock rom, SIM1 (2G/3G) can't connect to cell network, if I check IMEI with dial *#06# its null/null, but if I just use SIM2 (2G), IMEI still there and network still works. Please help me! I want my 3G back.
If radio off, sim1 card detect but no service in status bar. If radio on, no sim card in status bar and IMEI null/null
P.S. : Sorry for my bad English, I am Indonesian
om minta stock rom nya advan s4k sc7731 & sc8830
From an upgrade he stopped receiving GPRS signal both slots in my Xiaomi mi4i.
I've tried everything, factory reset, load roms from TWRP recovery from ADB sideload and from FlashBoot. ROMs development, global and weekly roms, and happens all the same, impossible to receive GPRS, GSM and WCDMA signal.
- No coverage icon appears on the card itself detects the mobile operator, but if you go to Settings / SIM card is deactivated status for the two and there is no option to activate.
- If you go to call tells you the radio is off and take away the airplane mode.
- The IMEI SIM cards is not lost, if frame ma * # 06 # IMEI appears both SIMs slots.
- If I go to Settings / About the phone / state in state service said Radio off / turn and Cellular Network Data desconnected state.
- If I go to Settings / About the phone and pulse several times on Kernel version, entered the Test Hardware, skewer in "3. SIM card" and the only information provided it is that it detects the SIMs but the test result is Fail.
- If I go to Settings / About the phone and pulse several times on internal memory from this menu you access to information from the SIM cards (Phone information). That I can see:
- Phone number:
- Current network: off
- GSM service: Radio Off
- GPRS service: disconnected
- Network type: unknown
- There are few buttons turn on radio, select the type of network does not work etc but the option to enable it.
If anyone knows how to fix appreciate it.

Try download the full rom zip and flash using updater app.
This will not erase your data and app.
