I have already made a couple of different sizes, which are available here, along with dzo's original custom Oxygen 100 /system hboot.
The caveats are:
- I am not responsible for any brickings which take place as a result of you using those files.
- Flashing HBOOT is a critical operation. If you mess up, or it messes up, or I have messed up, your phone will be bricked.
- I haven't tested them, but I have compared the hexdump output to ensure they haven't become corrupted and checked the md5 multiple times before zipping. I also generated them on a computer with ECC RAM, which should rule out any corruption caused by bad RAM.
- Unzip the file before attempting to flash it.
- Always check the md5 of the hboot immediately before flashing. The md5's are located in the zip.
If anyone has sensible suggestions for HBOOT sizes which will be useful to the community as a whole and not just an individual preference (and that includes HTC sense 3.0 people who need a massive /system) then please comment below.
