A suggestion for the benefit of the ROM chefs / users

---

Hi all!

Downloading custom ROMs is VERY cool, but a bit of a pain sometimes because the downloads are huge. I have a suggestion about how this could be resolved.

To explain my idea, let's look at how you would flash a ROM using the new method being suggested. You'd need the following things...

- USPL (as usual)
- Custom RUU (as usual)
- 'Control' ROM NBH

Here's the first difference. The control ROM in my proposal is the widely circulated HTC ROM NBH, which can be found here. You'd keep the NBH from this ROM (RUU_Signed.nbh) named as HTC.nbh, and it would be used by all subsequent updates.

So let's imagine that I have a device (USPL'd of course) that I want to flash to the T-Mobile ROM. I'd make sure I had a directory with the Custom RUU and Control ROM NBH in, then i'd download the file from the ROM creator. In this file would be a batch file, a ROM patch and the patcher. The batch file would patch HTC.nbh to T-Mobile spec, then run Custom RUU. The beauty of it? The download would be very small!

Would it work? YES! And to prove a point, please check out this post - where you'll find Orange, T-Mobile and Tilt ROMs in tiny downloads based off the control NBH. ROM chefs - let's start using this system, which i'm calling 'Kaiser TLR ROMs' for obvious reasons.

ROM chefs, to create the patches you just need to use bsdiff, which can be found here. Use the syntax 'bsdiff HTC.nbh YourROM.nbh YourRom.patch'. You can see a sample batch file in my link above.

So... what do u think?

I don't get it once your HTC is HardSPL'ed then there is no CID lock and you can flash any rom to your device. Most rar files containing the RUU_signed.nbh are only 40-50MB thats pretty small and can be deleted when your finished flashing. To me this seems like a lot of extra work for the cook(sometimes me) and more support issues I find it easy just to upload the ROM i made to rapidshare or some other file hosting site and people can download as they like.

40-50MB is a lot bigger than 6-7MB.

It's not a lot of extra work at all really, it's running one command line, and distributing a couple of files.

I think patching definitely has potential, not least that they are a lot easier (and a lot less illegal?) to host.

Sounds interesting about the legal hosting capability for diff ROM files instead entire ROM. The ROM archive goes down in the past for the M$ pressing . If we can archive only diif ROMs, this can be one solution to take back the ROM archive into the FTP at XDA.

One offtopic question, where did you get the Orange Shipped ROM for Kaiser?

Cheers.

I didn't, it's a dump and repack, as is the T-Mo one.
