Custom HBOOTS…update…

I have decided to release a win32 console app which allows you to generate your own hboots.

This console app is based on dzo’s code which patches the correct locations of the hboot in order to change the MTD partition table. I take no credit for figuring out the patching part of this app.

The features of this app are:

  • Custom partition selection and several checks to stop you trying to do something silly.
  • Ability to label the hboot (max 9 characters), it shows as AlphaRev <label> when you boot to the bootloader.
  • It patches the latest AlphaRev hboot (6.93.1002).

The limitations of this app are:

  • No checksum check of the source hboot, you have to do that yourself
  • No way of being sure that the patched hboot isn’t corrupt, it does a basic file size check, but that is all.

The caveats are:

  • If this app produces a corrupt hboot and you flash it, your phone IS bricked, and that really isn’t my fault, as ample warnings have been given and as far as I know the app works correctly
  • Reasons for corrupt hboots could be bad RAM, filesystem corruption, or maybe a bug in the app…
  • If you really want to check to make sure your computer is generating good hboots, check the hexdump output and compare it with a known good one. For example, generate one with 100 MB system, 5 MB cache, then dump the hex and compare with the Oxygen r2 hboot from, they should be identical apart from the label

Just double click hboot_patcher.exe or run it in a console window and read and follow the instructions. If you do something silly, it will tell you off and abort.

I do assume that you know what you are doing, so don’t forget to do fastboot reboot-bootloader and fastboot erase cache before attempting to boot to recovery to restore your ROM. :)

It also runs successfully under WINE.

Again, if you are scared about possibly bricking, then don’t use this tool. :P

It is available here.

  1. Really useful to help make the best of the Desire's limited internal memory.

    I use a home-cooked ROM so it's great to be able to tweak the partition table to fit my needs. Thanks!

  2. Hi!Thank you for your work! What do you think about this?

  3. Hey bro, can I bounce a few ideas off you referring my foray into custom unit for HTC Vivid?

    I am gsleon3 @ XDA, former admin/retired mod.

    Please let me know how we can converse. Reach me at gsleon3 at hotmail.


  4. Any chance of sharing dzo's code? Didnt find it on any thread on XDA that he authored.

  5. can i use this tools for desire cdma?

  6. No, you can't use it on Desire CDMA hboots because they are totally different.

  7. The HBOOT on AlphaRev's site is version 1.8 and has a md5sum of 7bd5234711364880de1fa982dcf3a2d6

    I assume this works aswell with your patcher?

    But hey assumption is the mother of all fuckups :p

    1. Don't see why not. People are still using Desires lol?

  8. Your link is dead. Could you please update it?

    1. It's in amongst this zip of all the stuff from the server:
