Unlocking BT Home Hub V1 *Upgrade at your own risk*

[broadbanduk]

hi ninj
yes it can be done ....!!

[Dimension]

I have decided to go ahead and use my HHv1 as my wireless modem/router in NZ, however I am going to firstly need to ship it over here! I think I will only need the box and the power for it.

If the DSL cable it longer than 1 metre (I can't remember) then that would be a plus if someone could confirm this. Also, could someone tell me if the USB that comes with it is over a metre long?

Would someone be able to confirm the weight of the items above so that I can work out shipping costs?

Thanks in advance.

Hi Dimension

I've stuck mine on the kitchen scales along with the original box, the Power pack, the USB cable, the DSL cable and two filters .............and it's just over 1100gms I reckon
Looking at the cost of sending a 'small packet' of approx that weight to a Rest of the World destination would be about £12 - £14 I reckon
I also reckon the USB is probably 2m and the DSL is nearer 3m.......thats using the crude method of holding an end in each hand stretching out both my arms to gauge it ( and I'm about 6ft tall )

Hope that helps

Anyway, back to the V1.5

I've tried to restore the amended file and I just appear lose connection with the box, although it doesnt appear to be doing any reloading ?
However if I go to backup again and save the config to the PC once more. I appear to have have lost the entire line that used to have BTHOMEHUB@ etc etc ?
I have also tried telneting into it and, via the menu, trying to alter the PPP settings for the one entry 'internet' ?
I've also tried deleting that one entry and recreating it from scratch
However, whatever way I try it just says unable to set user name

Hi I'd like to help try modding a HH v1 to something less restricted.

As I understand it the OS for this consists of two parts.
The CFE and the Main OS.
So far the "fix" has been to modify a stock Thompson firmware to make it look like a BT firmware.
Sadly since the CFE & Main OS don't match up we loose DECT.

I'd like to whole flash a Speetouch 790 firmware as it would seem to be identical hardware.
http://wiki.openwrt.org/OpenWrtDocs/...tDocs/Hardware

What I have :
JTAG cable
2x "Donor" Home Hubs
Linux OS

What I *think* I need :
Help performing a whole flash backup.
A full flash copy from an unlocked 790.
Help performing the restore.

Thoughts ?

Quietlife2k, I am not sure that I understand your proposition. Do you have the TG790 Firmware (or the WRT Firmware compatible with the TG790)?

If you do have this (these), you will probably need to patch the Board Address in the firmware as we did with the ST7G Firmware and then flash it using the Speedtouch utility.

Hope I'm not drifting this off topic folks

but I was working on a new v2.0 HH and when I restarted it the box appeared to do a factory reset ?
I lost all the settings that I'd changed and the Admin screen went back to the 'change password on first use' page ?
I've not reset it since so any idea how you 'save' changes ?

My proposition is to find some helpful person with access to both a JTAG cable and an unlocked TG790 and :

Obtain a FULL flash backup - including the CFE of the TG790 via JTAG.

Write that back to a HH.

See what happens....

I need help with :
Backing up a HH whole flash (in case I need to restore).
Obtaining said TG790 firmware.
Help writing it to a HH.

i have a bT home hum and i upgraded to speedtouch 7 a while ago and it perfectly fine. thankx to the users in the scream. my bt hub phone stoped working i am currently on AOL and the home hub works fine on AOL.
my question is dat is there any other upgrade avalible dat i cant use my hub phone and still connect to AOL

Good Luck QuietLife.

Is there any difference between TG790 and 7G?

I found this website in my perusals, the guy that runs it seems quite knowledgeable and contributes to the Whirlpool forum.

Wish I could help, sure be great to get a full fix.

[Quietlife2k]

I like you am dependent on the web for my info, but if openwrt is accurate - then no - the hardware in the 7G is ever so slightly different :

http://wiki.openwrt.org/OpenWrtDocs/...tDocs/Hardware

It is my understanding that the 7g is based on the Broadcom 6345 whilst the homehub / TG790 is 6348.

I am willing to try a full flash from a 7g if anyone has one - for as long as someone shows me how to backup the homehub first - whilst I have two that I am willing to brick I'd rather not brick them unnecessarily ;-)

once uve done that can u update the hub?

[Quietlife2k]

Ummm kind of.

If I can flash a homehub with a TG790 CFE & firmware then the home hub becomes an IDENTICAL clone of the original TG790.
Since the hardware is the same the CFE matches and it should accept the standard stock Thompson TG790 firmware images, and all features and functions of the new "TGHH790" hybrid should be functional including dect..

There are probably some issues with having identical MAC addresses on two different units so this may only be step one.

7G CFE & firmware however is a different matter.
Without testing I can only guess as to the outcome...
Since the 7G CFE does NOT match the hardware I would expect some or all of the hardware functions to be in some way impared.
Specifically I would expect the same outcome as the modified Thompson firmware has on a standard BT CFE. Namely that dect would continue to be an issue.
It may however allow us to continue using alternative service providers with newer 7G firmware releases without the dect.

This would also have the same potential issues with "cloned" MAC addresses as the TGHH790 solution.

i have modified source for hh jtag flasher. dont know if it works under windows.

when you use jtag to read from bthh the bytes in the file get reordered like this
in hex
00 11 22 33
1 2 3 4 normal file

33 22 11 00
4 3 2 1 gets read from flash like this

11 00 33 22
2 1 4 3 has to be written to hh like this

theres a program floating around you can use to rearrange bytes its called
hexmoog
taken from other places:
Assuming you are looking at the bottom of the board
e.g.
http://mikenelis.net/bthomehub/

Then the lowest solder pad is ground. ( lets call this pin 1 ).
pin 2 would be TDI
pin 3 is TDO
pin 5 is TMS
pin 6 is TCK

also
tp32 tdo
tp33 tdi
tp34 tms
tp35 tck

Is this safe:

I read somewhere

"Basically if the DNS could be edited, and if a 'hacker' was able to gain access to the customer's network, then the your valid DNS could be replaced with a spoof one which re-directed all the customers enquiries, allowing the interception of private traffic e.g. banking information."

I don't know what DNS is, I do not know much about networking, IPs etc..


please help

If i do unlock the hub, will I still be able to use wireless, I have bought a ps3, so would like to go online
