THG3000 VS THG3000G V2

[gipjon]

The THG3000G V2 has a dual channel differential amplifier designed to drive full rate ADSL2+ signals with very low power dissipation. The Le87251 contains two pairs wide band amplifiers designed with Microsemi's HV30 Bipolar SOI process for low power consumption in DSL systems. The amplifiers have an internal fixed gain, which helps to eliminate external feedback and gain setting resistors.

The THG3000G v2 also has a linkcom LGT 1502 G . Fast Transformer

The THG3000G V2 also has an extra Bridge rectifier and a few extra capacitors

Hi @gipjon where did you find this info? Is the THG3000g Ver2 different to the THG3000g?

[gipjon]

I decided to dissect a few routers trying to work out what other routers this motherboard is in and i cam across the difference. 

They have the same apex motherboard but the THG3000G V2 has the extra chips soldered on the board 

I have uploaded both boards . I got the info from the chip manufacturer

Interesting, here is a picture of the board in my Technicolor DGA4231. The Technicolor DGA2231 is the GFast version. The Technicolor firmware is so much more configurable. (but I can't get any updates as Technicolor say it is up to the ISP who originally shipped it to supply)

[gipjon]

So it look like the THG3000G is the G FAST DGA2231 And the THG3000 is the DGA4231. 

as far as i know there is no way to flash this router at the moment.  Unless its using the same firmware as one of the other Technicolor router that you can flash . I use to run a Technicolor sse router tg589vac that i flashed instead of that awful square vodafone router . Saying that im still using it as a second wifi access point on my lan network 

[Jayach]

I've also got a TG589vac V2 which has later firmware but I doubt it would be compatible even if I could dump it.

I've not tried it on the Vodafone line, I can't imagine it would be any improvement over the THG3000/DGA4231.

Is your exchange/cabinet GFast capable so you could try it it?

[gipjon]

Not that i am aware of  . To be honest the tg589vac was a vast improvement over the square vodafone router .i was running a custom firmware 16.1 which i belive was a hacked ee firmware 

‐--------------------------------------

I did wonder if the ireland or spain manufacturer had a custom firmware for the SHC3000 because from what i read its the same vodafone firmware on both manufacturers 

Bit of interesting reading for anyone else https://hack-technicolor.readthedocs.io/en/latest/QuickStart/

Seams to have a THC3000 custom firmware download

Looks petty certain, this is the label on one of the THG3000's

 Edit: The labels on your two boards also confirm it.

[gipjon]

did you have a look at the firmware above

[Jayach]

Yes I did, it sounds interesting but is very much a work in progress. There will need to be a full formed firmware file before I can use it. Soldering on serial ports is further than I want to go.

He is also using the board from the SHG3000 which is surprisingly different in layout to ours and already has a SFP port fitted.

But a good find.

[alwaysreading]

going back to the 3000 vs 3000g 

think the amplifier on the 3000g is interesting 

[alwaysreading]

i know the vox3 is a thg3000 or a thg3000g v2 but im not sure if there is a thg3000 v1 or a 3000g v1

[gipjon]

hmmmmm thats a very good question and I don't know the answer to that unless the thg3000 is the v1

To be honest, I don't think anyone knows. If Vodafone do they are not letting on.

I only knew of the THG3000 and THG3000g. Most devices are never known as version 1 until the version 2 is released.

How does the casing come apart?

I can't see any screws so presumably its all clips, I've run a separator tool down the side gaps but can't get anything to pop out and I'd rather not damage the plastic by brute force. 

I want to add some active cooling, I'm working the 2.4ghz pretty hard and have had some trouble with throttling (presumably heat related).

Once you have removed the base, yes it's just clips. From memory I worked down from the top. Fortunately I have 2 THG3000's so didn't mind if I broke one, however they have both gone back together with so sign of damage.

I also have a laptop opening tool, from when I was working on Compaq's (like this one https://www.routerforums.com/attachments/cpq_wedge-jpg.884/, but mine is black.).

[doby]

Ok thank you. 

That tool is a bit chunkier than the one I tried with but I'll give it another go.
