Hi

My father brought me a Huawei B315s-936 from his work, he says a batch of them all suddenly died with the same issue.
Basically the thing powers on but only displays the power light and doesn't progress any further.
My laptop states that the cable is not plugged in via ethernet.

If I hold the 2 buttons at the top and the reset at the same time the router starts with power light, blue status light and the bars light.
At this point the laptop says identifying.
It stays in this state for about 60s before dropping to red status light then back to power light.

I'm waiting for a USB A Male to USB A Male cable to see if I can't get some connectivity to the thing to debug it.
Has anyone come across the same problem?

I hope this is the right section to make this thread.

Had the same problem after i done a push firmware upgrade. only power light came on sent it back for replacement. Apparently you must do a manual update not a push update.

Thanks for the replies. I'll try mess around with flashing new firmware.

Does anyone have links to Telkom firmware? A quick google search turned up ad filled cesspits.

Mine did the same. TelkOM said it happens after a power surge. Took it into the store and got it back 3 days later. Just needed a firmware update.

Router is bricked either by firmware corruption or the way you did reset it. Correct way is using a single button. Two buttons switches router to some engineering mode. You can recover by flashing using the same branded firmware, i.e. if you have router from Telkom, use Telkom firmware file and google for "Multicast upgrade tool".

Mine was bricked and I believe it was from the firmware auto updating. I just took it in and they fixed it.

Reading through that thread sajunky mentions that the power light means its ready to download and responds on 192.168.1.1. However in that state the PC will not pickup the ethernet connection as connected. Is that correct @sajunky ?

I tried connecting via USB as well but couldn't get the drivers to recognize the device by anything other than a broken ADB device.

It depends on whether firmware is in corrupt state (hanging during startup) or in factory mode. As you say holding both buttons bring up Ethernet activity, you should try this one. It is not precise saying that router responds on the address 192.168.1.1. It is actually listening to special 'multicast' packets on this IP, not neccessary 'responding'. Remember that Multicast Tool is designed to upgrade many devices simultaneously. All of these devices sit on the same IP address. Situation that is not allowed on IP networks.

It looks like you have 60 seconds time window to start transmitting multicast packets, good luck.

Hi

I can repair these routers. Bootloader is destroyed. This repair involves hardware mod before flashing new firmware.
