If you happened to brick your non-HiLink modem with the HiLink firmware, this guide will help you to unbrick it.

This guide apply’s to the non-HiLink Huawei E3276s-150.

You will need the following files:
-HiLink drivers Huawei HiLink Drivers
-Huawei E303 HiLink Firmware (we need it to initialize the device) Huawei E303 Firmware
– Latest Huawei E3276s-150 Firmware E3276s_Update_21.436.03.00.00
– Huawei Flash Code generator Huawei Unlocker

Steps:
1.Download all the files.
2.Extract and install HiLink drivers
3.Plug in your modem
4.Disconnect from network (I had a problem because my main router is on 192.168.1.1 and the device didn’t want to initialize, because it uses the same address)
5.Start the Huawei E303 HiLink Firmware and install. This will prepare your device for the proper firmware. It will return with an error.
6.Start the Huawei E3276s-150 Firmware and install, use the Flash Code generator to generate the code necessary for the flashing.

This guide can be used to upgrade your Huawei E3276 to the latest firmware.

This guide will work only if you if you have the following mobile modem:
-Huawei E3276s – 150 ( If not sure open the modem cover and find the sticker with the labels MODEL, IMEI, S/N.)
E3276 sticker
-Your modem must be the normal E3276 and not hilink E3276 (Check in mobile partner what your current firmware is.)

To check your current firmware open Mobile Partner -> Tools -> Diagnostics
Huawei E3276s - 150 firmware check

If the number starts with 21. then you have the normal one.
If the number starts with 22. then you have the hilink version and this guide does not apply to you!)

So to recap if you have the model nubmer 3267s – 150 and your current firmware starts with 21. then this guide apply’s to you, otherwise do not use this guide!
