Easily & safely downgrade your Hub 2B from 4.7.5.1.83.3.18 so you can unlock it.
Hi all I finally have a solution for those of you with Hubs on version 4.7.5.1.83.3.18 that get the Access Denied error when trying to use the Sys folder hack.
The solution was there all the time! I just had to find it.
Ok here we go.
1: Download the 2 files attached below and extract them to your desktop - password on both files is www.psidoc.com Both of the files are standard BT firmware updates. Versions 4.7.5.1.83.3.17 and 4.7.5.1.83.3.18
2: Make sure you are connected to the router via an ethernet cable. We're flashing a firmware here so we don't want any wireless hiccups.
3: Open you web browser and type in: http://192.168.1.254/firmware_upgrade :<--- yes it was that simple DUH!
4: Put in your password for the router.
5: Click the browse button and select HUB20B_4.7.5.1.83.3.17_PROD.rms as the update file.
6: Click OK. (You may be warned that all your settings will be wiped out. This is normal, and besides if it's a locked router you haven't configged to work your way anyway!)
7: The Hub update light will now flash 10 - 30 seconds and you will be asked to confirm the 'update' from 4.7.5.1.83.3.18 to 4.7.5.1.83.3.17 Click Yes.
In a few seconds the hub will reboot. The relay inside will click 3 times during the reboot and it will take slightly longer than normal to reboot to the blue lights - don't worry this is normal.
Give it a couple of minutes to sort itself out with the new firmware and you can proceed to unlock properly using the other tutorial in this section.
Advisiory: The 4.7.5.1.83.3.17 firmware is a bit of an unknown entity and I don't think BT ever publically released it, so after unlocking the router properly I strongly recommend re-updating back to 4.7.5.1.83.3.18 using the attached HUB20B_4.7.5.1.83.3.18_PROD.rms firmware using the same method as above.
If you have any questions / issues and success stories regarding this tutorial or anything to do with this method of firmware updating please post them in this thread: http://www.psidoc.com/showthread.php...uccess-stories.
