I think I've found a problem with the sense kitchen ROM for HTC desire with regards to busybox. As follows:
Firstly I flashed my kitchen sense ROM and all went well. A clean install of the ROM.
Then I wanted to upgrade the busybox from the rom 1.16 version. Firstly I tried downloading the busybox app. When I tried to install it came up with a message that superuser permissions were wrong and that busybox couldnt be updated. There was also a message stating that I should remind the rom developer to install busybox in the correct location.
Anyhow I tried JRummy's busybox installer, and after selecting the alternate location for the install the install appeared successful.
I powered down my s-off htc desire. Then powered it on again. It just hangs on the alpharev splash screen. Thankfully after removing the battery, I could still get into recovery.
This happens on versions 1.19, and 1.18 versions of busybox install (possibly all other versions higher than the 1.16 but I didnt try them all).
Also one other minor point. I selected for ROM manager to be installed in the kitchen, but it seems to have been skipped by the kitchen ROM maker.
Apart from the inability to update busybox the resulting rom is excellent and reliable and I would much preffer to stick with your ROM as opposed to other "stable" roms. Please fix it, or advise of a work around as I am a fan.
