  6. salams and good evening

    I have a zain saudi arabia modem e5577s-321. i followed the above guide. modem is unlocked but it doesnt connect to net with any sim including zain. the web ui is still zain. software is now 21.316.01.00.00 and web ui 17.100.09.00.375.

    please help with appropriate universal web ui

  7. dear Mr Srujan, i am trying so many options but nothing giving success. i will let u know if anything successful works.

  8. dear mr srujan. not yet. but i havnt given up. and i am trying solutions. once i am successful i will surely let u know. if u r in saudi u can call me on 0507551108

  9. ok HI all. Dear SRUJan. Your worries are over. Here is the method to get your e5577s-321 zain working again.
    Presently I think you are on your router with 21.316.01.00.00 firmware and zain 17.100.01.xxx.375 web UI dashboard versions. right? the problem the webui is zain and its not allowing to flash hauwei webui.

    I downloaded E5577s-321_Update_21.180.99.05.00.exe It downloaded smoothly but gave MMI READY message.
    I then installed mobile partner to give hauwei drivers for windows 7
    I then installed the webui dashboard version Huawei_E5577s-Update_WEBUI_17.100.13.01.03_MRE5.exe also went smoothly
    then I flashed universal E5577s-321_Update_21.200.05.00.00_Universal.exe It went smoothly
    then I even updated to the latest previous signed software 21.316.

    All is OK. One guy in Abha quoted me 180 Saudi riyals to fix. I refused of course.
    Zain office offered me some help but said you have to see the technical support open in the mornings.

    No need. everything is ok

    Ayyub

    • I have followed this step by step procedure and now my wifi device is working. My question is and I noticed that the statistics are not working, it is stuck to a certain value despite continuous usage. Also, the traffic indicator besides the signal indicator on the top right is not showing activity. Does anybody experienced this issues, and anybody knows how to fix this? thanks.

  10. Kamlesh, i start downloading the Universal master code tool but model 5577s-321 was not shown. I had already been prompted for a password after the fireware update installation but I dont know where to find it. please advise.

  11. Mine is E5577Cs-321 locked to Viva Network.

    I did all steps and when i started flashing with : Huawei E5577s-321 21.180.99.03.00
    router went into download mode and restarted suddenly and firmware shows error 19 download failed

    Then I did the “AT^GODLOAD” trick, it went into download mode but again the flashing failed with error code 13 this time saying:

    Update failed
    Current Firmware Version: 21.200.07.01.397
    Current Dashboard Version: WEBUI_17.100.11.08.397_MRE5

    do I need another firmware or it is unlockable?

  12. Followed the steps and firmware E5577s-321 21.180.99.03.00 flashing failed (error code 19)

    I did the “AT^GODLOAD” trick, router went to download mode, tried flashing again, I got Error Code 13 Updating Failed
