Good deal. (FYI the definitive fastboot guide is up above still :) ..)

Hm, yeah, that _was_ a stupid question. I tried first ‘kernel’ which is what I saw in some pages about fastboot. That didn’t work. Later, after already posting, I tried ‘boot’ and yeah it worked. But then I got too busy with other things and forgot to post the answer to my own question (until now but now you already answered…).
At first the whole thing didn’t work, at all, and my phone was dead (at least, no UI. Only access via ADB shell). After much searching, rebooting, trying to set permissions again and again and phone not booting, I finally realized that I miss-spelled a directory name somewhere. Then it finally worked like it’s supposed to! ;-)

Well, since its a boot image, maybe “boot”..?

Well, that did sound easy enough, but flash_image actually wants to know a partition to which to flash too. I didn’t manage to find online which partition that would be, so I’d be grateful if someone could enlighten me…

Sorry for all the simple questions!!

The easiest way is fastboot. Barring that, you can use flash_image. Copy it to the device (sdcard or flash) and run – as root:[code language=bash]$ flash_image boot.img[/code] and you should be good to go.

OK, great, thanks! :-) Now however, a stupid question to which I couldn’t find the answer on Google: How do I install this custom boot.img file? :-(
I can use adb, but for some reason I have never managed to get fastboot working on my machine so I hope the answer doesn’t involve that.

Cheers and thanks in advance for an answer,

None needed, the boot image didn’t change between 1.5 and 1.51 so you can just use the old one.

Hi,

Is there actually an updated boot-image for Android 1.51 for the dalvik cache hack?

Cheers,

There are a couple of things you can try:

“system” instead of “1000″

“/system/xbin/bb/chmod” instead of “chmod”

The issue is that there are two versions of chmod present on JF’s images. One is the toolbox version, which comes with all G1s. It understands usernames and not UID numbers. The busybox version, which JF installed, has more features but doesn’t know how to find Android usernames.
