Since i bought Huawei K3520 modem, I’m not do any experiment, because there aren’t so many people talk about it in the internet. Now I’d like to share about firmware upgrade for Huawei K3520/E169 and activate the voice feature.
K3520 is different with E169…??
The different thing is only the label, Huawei K3520 is re-branding by Vodafone and most of that modem lock by vodavone, and cannot be use with other services. And Huawei E169 is pure from Huawei, of course you can independently use any services.
Note :
Before do firmware upgrade, make sure your computer electric is stable, because if you are in the process and the computer shutting down, can make your modem broke. Better way you are use laptop/notebook with the battery inside and plug the electrical adapter rightly.
Download below file :
1. E169x_K3520Update_11.315.05.00.00.B418.rar
2. Mobile_Partner_11.302.09.01.539_Voice_USSD.zip
If you’re done, start the number one file first with double click and follow the process, like the captured below :

Unplug your Huawei K3520 modem from computer/laptop, and then plug again.
Upgrade Mobile Partner Software
if you’d like to use the voice feature, you have to install new Mobile Partner software with the link above, below the instruction :
1. Extract Mobile_Partner_11.302.09.01.539_Voice_USSD.zip
2. Run Setup.exe and follow the instruction until finish
if you’re done, you can see this captured

Thank You Ferymuch I was try this step and it’s work succesfull
thanks bgt , udah diupgrade firmwarenya, tapi sempet ngehang, trus dicoba lagi baru succesfull.
di Mobile Partner kalo USSD-nya nggak mau respon kenapa ya ??? setelah receive : teks kosong, aku pake simpati coba cek pulsa gak bisa…
btw thanks bro…..
mas saya juga make k3520 pas dibeli di wilayah saya cuma dapet sinyal edge/gprs, masalahnya sinyalnya kok turun naik yah apa modemnya yg salah?, masih bisa ditukar mumpung garansi.:D
anehnya saya coba di wilayah full coverage hsdpa, sinyal hsdpanya full stabil make kartu telkomflash, tapi ketika ditukar ke sinyal gprs only sinyalnya tetap turun naik, mohon advicenya mas .
saya masih make firmware bawaan voda ver. 11.314.12.02.00
gan, kalau udah di update sofwere yang lama ilang gak ya?
Thanks gan pencerahannya, tapi untuk modem K3520 kan sofwere bawaannya pake Join Air 3G (ane pake win7), nah aku coba pake mobile partner knp gak bisa ya gan?? bingung nich…, mslahnya law pake sofwere itu sering hang, mohon bantuan gan……
he he he td udah aku coba, eeee muncul tulisan data card not found maybe data card using other program,,, mlah tambah puyeng ni.. masalahnya pengen bgt nyoba pake mobile partner gitu….:D
gan saya pke modem k3520, tapi kec nya hanya 53,8 kbs dan hanya dapet sinyal gprs, klo dapet edge jd 200-an kbs, padahal temen saya yg satu wilayah bisa dapet hsdpa dengan modem yg ama dan provider yang sama, tolong pencerhanannya gan…
iya klo gprs ya mang segitu aja mas surya….
btw sinyal edgenya dapet brapa bar…??
coba settingan di modem dashboard (etc: mobile partner) diset hanya menerima sinyal 3G, kalau dapet 1 atau 2 bar lomayan juga koneksnya. Tapi klo dapetnya sedikit biasanya modem lebih panas….
makasih ya… saya sukses updatenya….. tapi saya mau tanya….. bisa gak HSDPA Di upgrade menjadi HSUPA..?? tapi saya yakin itu masalah Hardware…. bukan software…. bener gak… terimakasih…..
mas saya mau update kok minta password yah..padahal modem saya bisa untuk semua operator sdh unlock..terima kasih

kl yg buat e169 ada g bro?
trs kok download E169x_K3520Update_11.315.05.00.00.B418.rar kgk bs???
mas mau nanya klo aplikasi huawei yg bisa voice diatas di masukan ato dijadikan sofware bawaan modem bisa gak ya?biar antara modem ma sofwarenya engga pisah ranjang gitu mas.trimakasih infonya
dengan langkah di atas akan merubah Zero Boot CD yang ada di dalam modem huawei e169 dengan aplikasi dashboard Mobile Partner yang sudah Voice enable, jadi tidak pisah ranjang mas…..kan default aplikasi dashboard yang ada di pasaran untuk modem huawei umumnya menggunakan Mobile Partner yang belum support Voice.
