TFKC - The Froyo Kernel Collection

---

Hi fellas,

the intent is quite obvious, collect the latest boot.img that are usable for Froyo.
So here it is, the Froyo kernel collection with all the bugs...
Unless there is no unlocked bootloader we have to deal with the delivery of Moto.
The files could be found easily in the web, but you'll have to search.
I know that searching is very hard for some, so i decided to put it down here and collect some other useful informations in this little thread.

Kernel images (boot.img) sorted by kernel build date:

Korean 5.06 (SHOLS_U2_05.06.0_kernel-2.6.32.9-g4bc8ed0-20101108_update.zip)

African 5.27 (SHOLS_U2_05.27.5_kernel-2.6.32.9-g11068ed-20110305_update.zip):

Basically the arabian and the african kernel are the same.

All files are installable through OpenRecovery and might be renamed to update.zip.
You could easily extract the boot.img and use Nandroid alternatively!

For the curious, here's the official kernel source:
https://opensource.motorola.com/sf/f.../frs12183?dl=1

Disclaimer:
I did not re-pack these files myself, i just collected them.
If you harm your device using these packages, i'm not responsible.
If anyone is the best friend of w21529, wfp018 or r2d2 please ask for help.
If you are a motorola employee send the private keys to wikileaks.
If i made a mistake, tell me!

Thanks goes out to all the openminded developers out there.

@moderators:
If the attachments are getting to large tell me.

Cheers,

Example structure of MS1 boot.img:

0x0000 0000 - 0x0000 07ff   Android header, the first 8 bytes are the magic = "ANDROID!", followed by:
                            unsigned kernel_size,
                            unsigned kernel_addr,
                            unsigned ramdisk_size,
                            unsigned ramdisk_addr,

0x0000 0240 - 0x0000 02e0   id (checksum 160Bits)

0x0000 0800 - 0x0027 07ff   zImage

0x0027 0800 - 0x002a 77ff   ramdisk.gz

0x002a 7800 - 0x002b f7ff   n x 0xff + 0x0000 0100 at the end

0x002b f800 - 0x002c 07ff   key structure

The key structure at the end of boot.img is explained more in detail here:

Some more to come...

Have fun!

Maybe you can indicate the +'s and -'s of each one?

I think one has 4 point multitouch but usb bug included with it :P
One or two may have DSI bug, but not as bad as others

I agree, I'm still using the GOT leak kernel simply because I keep reading of various bugs on various kernels and haven't decided to change to any other yet. Although, I normally just pick the newest kernel and assume it had the most fixes - this is MOTO we're talking about (2.0 -> 2.1u1 kernel bugs anyone?)

Yupp nice idea.... need to gather some information though.
Need some days.

Could you please tell me which one of those is CM7 RC3 using?

Hey,
thanks for the comments so far...

SHLA_U2_05.14.0_kernel-2.6.32.9-20110224_update.zip is not the best source i guess. It contains a boot.img which is slightly too big in size.
Though this might not cause any issues, please be warned.

I got no SDK at hand... so i'm looking for an alternative to build a new update.zip.

Further comments are welcome!

Regards,

scholbert

I'm not sure if SignApk relies on the SDK - as it's not acutally part of the SDK, I think it just relies on JAVA, you could give that a shot - that's what I use (but I have the SDK installed so I don't know about dependencies)

That's right, sorry for confusion and thanks for clearing up.
It just works with Java on your machine. The tool is called signapk.jar.
I found the package on my workstation... uploaded new Brazilian kernel (debug version)

Maybe i'll delete the standard version...
