E5186 Firmware Update Guide

My guide my how to flash firmware on Huawei E5186. Haven't got the time to create the image guide as I don't have a Windows machine with me currently. So you have to refer to my text instruction.

1. Configure the IP of your computer to 192.168.8.100 and the router IP to 192.168.8.1 at your LAN properties. Leave the Subnet Mask at 255.255.255.0
2. Connect your computer to LAN 1 of E5186.
3. Run Multicast Upgrade Tool. Set the Network Card to your Ethernet interface.  Tick force upgrade and select your desired firmware.
4. Put E5186 into flashing mode. With the device off, hold the Wi-Fi and WPS button at the right side of the device. Turn on the the device while holding the Wi-Fi and WPS button. Release the Wi-Fi button immediately when you see the Wi-Fi LED flashes. Release the WPS 1 second after you release the Wi-Fi button.
5. Click Start on Multicast Upgrade Tool. It should start sending firmware to the E5186. If it doesn’t, start all over again. Getting into the firmware update mode is tricky.
6. Wait for at least 7 passes. Notice that the counter at the package file send time.
7. Stop Multicast Upgrade Tool and reboot your router.
8. Remember to set your IP back to auto and operate your router normally.
9. Your device should be updated, check the firmware version and webUI version.

No warranty provided and you may brick your device.

Here's the firmwares I tested
21.310.01.04.418
lmt branded. Best firmware as it is able to display the most amount of information at the interface. You can see the selected band and the CA status.

21.310.01.01.182
Telia branded. My second favourite firmware as it is able to select the band from the webUI itself without the need of a tool.

Most of the firmwares have a telco branded UI and it doesn't matter. It will not lock your device.

Your router is one of the special batch which require another way of flashing the firmware. But you successfully updated the webUI.

It comes with IPV6 support enabled and more information displayed.

Anyway, you already updated the webUI. I can see you have the lmt webUI now.

Set to B8 900MHz but seem to be able to get 3G only.
And the speed sucks 

That means only webUI is updated but not the firmware itself right?

i manage to improve my speed from average 20+ to 40+ with external antenna, putting near window. I'm happy with the antenna.

Anyone with E5186s can work with voice call and internet together at the same time?

Yup

Hi blacktubi, in this special case, what kind of special method needed to upgrade firmware 

Would you want to try if it involves risk of bricking your modem?

That's how I get mine updated too.

Connection will switch from 4G to 3G once call is made or received, provided setting inside router is "4G preferred" or "Auto"

Yes, i know will auto switch from 4G to 3G. it is normal, but while at 3G during call, i can't get internet at all.

i set to Auto.

Can you try whether it works?

if i force to 3G only, i can get online. This tell me 3G has no problem. Only something wrong during call.

wont change much..... this is mobility internet...

hence the sim is in your phone.. how u play game while somebody is calling you? lol... 

Been googling for the whole morning, i found out that:-

When i firstly received my e5186s from taobao, although model is black tele2, but webUI is Huawei.
That is why I got this software version: 21.306.01.00.00

Only then last night i force update to lmt, webUI becomes lmt
Yet the software version is still the same, as it will forever stuck with its original vendor

Am i right? blacktubi
