If you simply want to be able to use Telnet/FTP/change the user.ini on your HH, but stick with BT, then a less-invasive software-solution is probably best for you. If, however, you want to be able to unlock all the features of the HH and to be able to use it with other ISPs than British Telecom, then read on.
Create new partitions, pivot-root to them then un-mount previous disks
Save your existing filesystem
(not in the existing README - make sure you do it!)
Flash new unlocked filesystem
(this is the only stage that is invasive)
(fs files prepared by PsiDOC)
The effort has been made to fully script this, to help avoid mistakes. Although a knowledge of Linux computers will help (the HH is a Linux computer) it is not necessary, as long as you can follow instructions.
The replacement filesystems have been prepared by PsiDOC & previously could only be JTAG-ed in. Changes made to the stock firmware are detailed here.
Simon has also provided some software tools if you want to explore the HH firmware further. This can only be done on Linux/Cygwin, due to the case-sensitivity of the files employed by Thomson. It is a 5-step process:
Un-squash the fs
Un-wrap the Thomson archive
(provided in this model as a single file)
Re-wrap the file collection to a single file
Re-squash to a fs
Bear in mind that it is entirely possible that your changes may cause the router to sieze up. JTAG recommended for backup. If you simply want to examine/play with the files, a full r8.1.F.4 fs is here. _________________ Alex Kemp
The script is derived from some update* scripts utilised within the BT firmware, and clearly used as part of firmware updating. I double-checked with the original scripts and, sure enough, the last line above is supposed to be a `>>' (append) and not `>' (add to new file).
Now, I do not have a BT-HH2a to check out this amendment on. Hopefully, I haven't screwed the whole process (it will not cause any destructive effects if so). Someone is sure to inform me if so. _________________ Alex Kemp
