    hot HOW TO UNLOCK HUAWEI E5577s/Cs-321 [Usbloader Method]

    Today we have in our hands another variance of E5577 from MTN almost slimilar to E5573 with LCD and increased battery strength to 3000mAh. This guide is not new; same old boot shot method. Follow this guide you understand and wish to unlock your E5577s-321.

    The E5577Cs-321 and E5577s-321 uses almost same firmware files. I have tested the files on both devices. It works perfect.



    REQUIREMENTS

    1. Balong USB downloader
    2. Huawei Drivers V5.0xxx
    3. Huawei Firmware 21.180 (usbloader already inside)
    4. Huawei Firmware 21.316
    5.WEBUI17.1xx



    GUIDE

    1. Install the Huawei drivers

    2. Disassemble and boot shot test point with gnd as shown (just like other boot shot already known)




    USB COM detected- you should have PC UI com port detected in device manager

    3. Run Balong Downloader and flash Usbloader.bin file from Huawei 21.180 firmware



    [size=large]4.Install firmware 21.180; run setup updater to install finish[/size]

    [size=large]NB: LCD shows installing during firmware update process[/size][/color





    Your device should reboot into Factory Test Mode (FTM ) showing on screen



    5. Install huawei WEBUI17 ; run updater to install finish




    6. Install Huawei firmware 21.316



    You should see battery error on screen at begin to resume user information; dont worry just hold the board and insert the battery gently


    It should now complete and reboot to Huawei Logo and proceed to main interface



    7. Note your imei ; read modem info with dc unlocker and *write IMEI via AT command AT^CIMEI="IMEI"



    You can now do a quick repack and insert Sim; WebUI as Usual ...........






    3g and 4g all Working Perfect

    Unlock Done
