  1. Hello..

    SSID: Zain, KSA Locked

  2. dear Admin, i have done all the steps successfully as shown above with pictures…….. please tell me one thing; will i get connects 4G with any sim cards now or only 3G?

  3. Dear thank you so much for your kind suppport…. please let me know can i use this device in any country now? What about in pakistan? Which network will get 4G in pakistan on that device?? Waiting ur answer

    • It is unlocked, so it will work in any country now.
      Your second question: 3G/4G ?
      Nobody can answer it, bcoz it depends on the frequency supported by the router and the frequency used by the service provider. For ex Zain run on 1800 MHz. So to know whether it will be 3G or 4G in your home country check the frequency used by the internet provider… it may be 4G…

  4. Dear Admin

    Pls advice me, I have tries unlock my E5577s-321 as per your instruction on the link.

    I have done all the process as per instruction in the link, at the last when I have to reset FMT, the software got hang and now the problem is the Device when i start it shows only Huawei Logo with Huawei Text wirtten.

    I kept it on for almost a day but there is no change.

    Pls help me to resolve this.

    • Did u flash both the firmwares before clicking reset FTM????
      If no, then the process to recover the device is different. if Yes, remove the battery and put it back. It should work. If is doesn’t work, Auto detect again and choose reset FTM.

    • Disconnect cable. Remove the battery. Put battery back, connect USB cable, Login in app, autodetect, download mode and flash second firmware.

    • It is all about the frequency on which the router works and the frequencies supported by the router. Unlocking only remove the lock placed by the company to disable the other network SIM card. Unlocking cannot change the frequency that the router support. You were supposed to see the frequency manual of your router before starting the process. Frequencies supported are printed on the box also on which the router is packed. The other model of Zain, e5577s-932 will work 4G with all sim because most of the frequencies are supported.

  23. I Havent yet purchaced the code but when i launch the program and i login it says wrong name or password i need this to work
