Huawei E8372h-608 Unlock Firmware

[Vin Raichur]

Im looking for a good router (with at least 3 LAN ports) for the Telstra 4GX USB (HUAWEI E8372H-608). Looked at Dovado, but they don't support the device. I have searched this thread but didn't find anything. Does the TP-Link TL-MR3420 support the USB Dongle?

In the Melbourne Metro catalogue (20 June 2018 for the next 6 days), Coles is having this on sale at $14. I had to call around to see whether they were in stock. Seems to be some left at The Glen, Glen Waverley.

It doesn't seem possible to flash the Telstra firmware back (or even take a backup of a device with Telstra firmware). There is an option to flash with a different webui which restores signal strength.

I presume that you overcome the last hurdle you mentioned when flashing the updated firmware ie. that of software not detecting the modem. Seems like a prevalent theme with your PC. Try using another PC

Not too worried about it, it's mainly the Telstra stock one (unmodded) that will work fine. The ACA Database shows higher EIRP on Optus than Telstra at the nearby tower so I had thought there may be benefits with Optus.

Failing that there is a way to disassemble the modem (one screw) and short a pin on the modem to the ground while plugging in the modem to PC. Then you are able to flash recovery software (similar to the first downgrade step in ozbargain) and proceed from there. At least that is what I read

Just bought a Telstra Pre-Paid 4GX USB Wi-Fi Plus: -phones/prepaid-mobiles/telstra-pre-paid-4g-usb-wi-fi-plus for backup, if, more like when, my soon to be new NBN FTTN connection is activiated in a couple of weeks.

Once I activate the sim, can I also put the sim in my phone and use it in that, or does it get locked onto the USB stick's IMEI? If I can swap it over to my phone, iPhone 4S, will it allow me to do voice and text, or just data, or neither?

Followed the config steps above and set "my L.I.M requires a username and password" and "let router control the internet settings" along with upgrading the firmware to 7.3.21 but it won't connect. Under modem status I can see all the details so the TINY is regnosing the USB but the network signal light just keeps flashing blue. APN is set to telstra.extranet.

I have the subject device, which came unlocked, and I have installed in it the BOOST SIM card from my Telstra T84 phone, so as to operate the dongle as a WI-FI hotspot in my shack, and hooked up to an external antenna. I can now walk around shack and immediate outside while accessing the internet on the T84 (could only connect before when plugged into the external antenna). But, problem is that because I have no SIM card in the phone, I cannot make voice calls or send text messages.

Is there any way that I can make voice calls, send text messages, short of buying a SIM card for the phone? Or, should I be looking at some sort of repeater to rebroadcast the 4G and 3G that I catch with my antenna, and put the SIM card back in my phone?

Upon research, it appears what might suit my purpose is a 3G 850Mhz repeater, so that I can have mobile phone coverage around inside my shack and maybe just the immediate surrounds. The subject Hauwei dongle allows me good mobile 4G internet (data) connectivity via its WiFi hotspot, but I just need something to give me the moble 3G phone connectivity.

I do not need a booster/amplifier, as my Yagi antenna sends down its cable a good signal; if I could just re-radiate it inside my shack, I could put the BOOST SIM card back in the phone and all would be well.

I'm wondering, what if I attached a small antenna to the end of the roof-top Yagi antenna cable that comes into my shack? Would the 3G & 4G signal be re-radiated/transmitted, so that I could get a usable wireless signal on the ground? I've got a Bi-Quad and a Panel antenna available for this purpose. Might be a issue with interference between the signal from the tower and the re-radiated signal?

Leave the phone connected to the antenna with hotspot turned on. Get a cheap wifi-only tablet for browsing and a bluetooth headset for calls. If you need more range than bluetooth allows then get a bluetooth gateway and plug in a DECT cordless phone.

WF: Passive Coupling I do not need, as the T84 phone has an external antenna plugged into the port at the back of it, and I am, as I write this, accessing the Whirlpool site on my PC via a USB tether to the T84.

As the T84 uses 3G for voice calls & SMS, I'll need to have a separate 3G antenna, feeding a signal to a 3G booster/repeater, so I can walk around and be mobile. But, they seem to either cost a lot of money for proper gear, or risk something cheap from China.

WF: Interesting idea.... Actually, I only make and receive a few phone calls a month on my landline, so I think I'm investing too much time & energy trying to set up a mobile phone access here at my location, which just isn't necessary!

In my previous post, I forgot that my problem was that using the E8372h-608 dongle requires that I take out the BOOST SIM card from the T84, and then put it into the dongle, but then the T84 doesn't have a SIM card, and so it can't make or receive a 3G phone call! Obviously I don't want to have to go through 2 SIM cards just to use a mobile phone which I would not use that often anyway.

So, I think the only way that I can have mobile smart phone access at my place is to shelve the E8372h-608 dongle, and get a 4G 700Mhz and 3G 850Mhz booster/repeater. But the most economical way to have mobile phone coverage would be the Bluetooth handset route.

I've also got a T85 in a box, but the problem is that, if have the T84 connected to the external antenna, and acting as a WI-FI hotspot, the T85 doesn't have a SIM card! I don't want to pay double! There must be some way to call from a phone without a SIM card, via the SIM card in another phone? Wait, that's what the Bluetooth handset was for? But, the T85 and the T84 both have Bluetooth............ can't I use the T85 without a SIM card to make a phone call via Bluetooth to the T84 SIM carded "base station"?

Be careful as many are not approved for use with any of our Australian Telcos. If not approved & authorised for your area you risk causing interference with other users resulting in confiscation & a fine.

I just got my two Telstra "Tough" phones to be on Bluetooth together, but it seems like the same problem exists as with WI-FI....... T85 (without SIM card) could connect with the internet via Bluetooth to T84 which has a SIM card and a connection to an external antenna, but could not make a phone call.

But, what does this actually mean? If I had one of these, what exactly would it be having Bluetooth connectivity to? In my situation, as described in posts above, Does that mean that the Uniden 8115 can make and receive mobile phone calls & text messages via Bluetooth via my Telstra T84 which is connected to the external antenna? If so, why is my "smart" T85 (w/out SIM), which also connects via Bluetooth to the T84, incapable of doing the same? Does the Uniden 8115 need a SIM card?

When these bluetooth enabled cordless phones first appeared on the market they were targeted at people who wanted an ordinary cordless phone to plug into their home landline connection PLUS wanted to be able to use the same cordless phone (remember you can get them with multiple handsets to spread around the house) to also make & receive calls via their mobile phone.

Whilst there may be differences between the brands & models, my Panasonic is probably fairly typical of how the bluetooth operates. The cordless phone simply accesses the address book in the mobile phone to allow you to select who you want to call in the same way as my Garmin SatNav unit in the car does. Your contacts appear on the cordless phone's screen (just like it does on my Garmin SatNav screen) & you then select who you want to call. Note that the SIM MUST be in the mobile phone for this to operate.

The bluetooth connection from the cordless phone's base station normally has a range of about 8m to 20m. This means the mobile phone needs to be within that range to operate successfully. The cordless phone's base station then transmits the mobile phone's address book via wifi to all the handsets. This wifi connection has a much stronger signal than the bluetooth & so the handset can often be placed 20m to 200m from the cordless base station.

I should add that my Panasonic bluetooth enabled cordless phone has antennas on the back of both the base station & handsets. This gives it much better range than some other models that contain only internal antennas.

My computer's motherboard is one of those Gigabyte ones with On/Off Charge, which allows USB devices to be powered / charged even when the computer is off. This is all very nice for keeping Wi-Fi going, but when the computer is switched back on the USB connection can be *very* slow, like about 1% of what it should be. Unplugging and replugging fixes it, so if the modem is within easy reach it's just annoying rather than a major issue. Logging into the modem and rebooting it also works, if unplug/replug isn't convenient.

I have this e8732 Telstra variant with a Vodafone data only card. Has been working fine plugged into an Asus router for months. It's on a boat, and was switched off for 3 weeks or so while the boat was out of the water. Arrives at the boat today, switched the router on and no internet. Kept on trying to direct me to the USB dongles GUI.

I've messed around and confirmed no Sims allow a connection. The modem recognises when a sim isn't present. Trying to reset via the reset button doesn't work and nor does it via the GUI. It just results in the wifi and middle led flashing green (wifi) and red (middle) so there is nothing I can do to Do a factory reset. I have done all of this with it both plugged into the Asus, via the Asus wifi, and also plugged into a PSU and using the dongles wifi directly..
