About how to write imei number for MTK 65XX from fastcardtech.


Two apps you may need! Please download it here! http://pan.baidu.com/share/link?shareid=129564&uk=3022339290

But the two apps are chinese, and now i will explain it step by step.

1.The first one to write imei number is m44 tool box.

This one can run with your phone language if it is English, then, here is the step:
engineer model– engineer model(MTK)– GPRS—

Then you will see two blanket tables at the top of the screen, all you need to do is just to write 15numbers in and then restart!


2.If you can’t see the blanket tables in m44 tool box, you may need this one to write imei number.

mt65xx is made for all these 65xx phone to wirte imei number, but the short is all are chines..

But it’s okay. You can see the details here!

Notice, if you lost your imei number, you will not see the original imei1 and 2, what you need to do is just to write new1 and new2 and then restart.

3. still need the m44-tool box. if the one i upload can’t be used, then pls try this one.(need root your system)

Here to download.

1. send the imei.bak to you sd card 2.

2. open the m44-tool box, you can see the imei backup restore. There’s a bug. if your system is english, it will focus to stop. so you need to remember the position of “imei backup restore”.(if the app you used before does not have this function, pls use the one i send you now.)

3. change the system language to chinese, and enter the m44-tool box again. click “restore imei number from sd card 2”

and then pls reboot your system, and all done.

If all those can’t work, pls contact to techsupport@fastcardtech.com, the guy will help u write imei number case!

    Hi there!

    Im using a s4 superking v3, I accidentally erased the imei on the boot screen, can anyone help me out?

    Warm regards,

  6. Hanchu

    I’ve ordered the Goophone i5s (MT6577 or MT6589): SN2013110158986.
    After flashing new Rom I lost mei IMEI too.
    *#06# = IMEI Invalid
    I tried the steps above but the two steps don’t work for me.
    – I have no blanket tables under GPRS
    – MT65xx Tool I get a chinese error message that it was failed to write

    I also tried a way I’ve found in the internet. Send an AT Command under Engineering mode – CDS Information – Radio Information … but it failed too.

    Could you please e-mail me also the 3rd way you mentioned before.

    I have a Bedove X12, MTK6577, rooted. I tried both procedures mentioned here, but both of them failed. The first one, with M44 Toolbox, the menu shows “Engineer Model”, and under it, “Engineer Model (Android)”, and not “Engineer Model (MTK)”, as said. Under this option there is no “GPRS” option, nor a way to change IMEIs, so I quit.

    With the second procedure, with MT65XX software, after writing both IMEI 1 and IMEI 2, and clicking the indicated button, an error message comes, in chinese… And the IMEI numbers keeps the same!

    I tried another procedure too, which I found seeking internet, where I can change IMEI numbers using the phone keys, using this:

    *#imei#6666# —> for SIM1
    *#imei#7777# —> for SIM2

    I got an “IMEI write fail” message!

    Please, someone have any other suggestion?
