If you remember, I got myself a HTC Touch Diamond. The only issues were the heavy Vodafone branding and the language couldn't be changed!
The solution was to flash a new firmware, but all the links in the xda forum were dead.
I had to go through dodgy websites to get the flash unlocker and the English ROM and I'm posting them here if you're having the same issue 😁
