[Q][DEVs] JB Boot.img - HTC Desire X

Hi people!
Can you look into this boot.img? After editing it with kitchen to support init.d scripts, ecc. I get a new JB boot.img that have 4.4mb, is this normal?
If yes, it can be used with 1.24 hboot, right?

If someone can give me some info about this kernel I will really appreciate this.

Hmm... What did you modify? Im sure you removed something to make it that small And I think you should have modified it using ubuntu (well thats the only way that I know to be able to modify a kernel and I don't use kitchen that much too ) correct me if Im wrong hehe maybe it should work though That would be awesome hurrah for not wating for the OTA LOL

4.4mb is not small... the actual size of JB boot.img is 4423 KB (4.31MB).

So.. Cygwin is a collection of tools which provide a Linux look and feel environment for Windows, so yes we can edit kernel on windows.
But I didn't edit manually nothing so far. Kitchen extracted automatically kernel & ramdisk to add init.d support and than it repacked it but the final kernel is only 4.4mb.
This is what I did and what I got

For me is 15.9 mb
Did they not update hboot to make larger partitions like /boot?

From where you got 15.9 mb ? a Nandroid backup ?
Get it from the OTA zip .. someone uploaded that somewhere before

It's the correct size of jb kernel. Just the recovery generate bigger with the backup. But it's need to be less then 4mb for 1.24 hboot. But if you really want to try the jb rom, there is a way. You forgot that we have two boot partiton.
1. Install the jb rom with recovery and do a factory reset.
2. Reboot too bootloader
3. Flash jb kernel to recovery partition: fastboot flash recovery boot.img
4. Reboot to recovery will boot to the jb rom.

I understand hehehe..
So kitchen remove recovery's backup extra stuff from kernel, also.
But what about two kernel partitions? There is not only one (/boot)?
Thanks,

No. The recovery is the second boot partition If you flash the JB kernel to recovery partition you can boot to jb.

Hehe.. Thanks for info.

Yes. But you need to "reboot to recovery" every time when you want to reboot your phone.

Ah.. you're right
It can be used the same thing for recovery?
I will not be surprised if yes.. xD

recovery image is bigger than boot partition, so no

@atis112,
The thing you mentioned, nice trick. I'm thinking of testing JB using that method. Seems safe enough to me.
So is there a JB ROM or backup which i can flash??? What i see is this:
1. Flash your modified recovery,
2. Restore the JB NAND backup from someone.
3. Install the kernel to recovery partition, reboot to recovery from fastboot and just wait.
Is that right???
Regards

Just a bit correction: Use one of your ics recoverys! (You have the old partition table) And i think better if we made an installable zip from jb rom. And so:
Flash jb rom from your recovery
Wipe data and cache
Reboot to bootloader
Flash kernel to recovery partition
Reboot to recovery from bootloader
Enjoy the official jb rom
I think it's the only safe way to use JB without OTA update. You can reflash a recovery and go back to ics when you want.
