Hi,
I had posted this in the Q&A thread, thought I would post it here as well.
Glossary:
boot logo: the static image you see when you turn on the phone.
boot animation: a series of pics in a zip file that are displayed after the boot logo.
Hi,
If you want to change the boot logo, you just fastboot flash logo logo.bin. It's mmcblk0p8.
The format is a constant string, 4 bytes, "SOL:" followed by 4 zero bytes, followed by 4 bytes for the width, 540, 4 bytes for the height 960, and the raw data of the image. Each pixel is 2 bytes, it's 565 format.
save a png as 540x960 called logo.png
$ convert -depth 8 logo.png rgb:logo.raw
$ ./rgb2565 < logo.raw > temp.bin
$ cat logo-heaader.bin temp.bin > logo.bin
$ sudo ./moto-fastboot flash logo logo.bin
Here is the source to rgb2565:

dumb question, had u tried this?

Hi,
If you want an example, try my zoomquilt2 bootanimation.
[BOOTANIMATION] HD bootanimation zoom quilt 1 & 2
Only downside is that things like "unlocked" show up on top of the logo, so design with a back background to avoid that.
Cheers!

I believe this post refers to the initial boot logo, not the boot animation that follows.
yeah, the OP got confused... now i dont know if i should try this
Guys, if you read the zoomquilt thread, it replaces the logo.bin and boot animation. OP didn't confuse himself.
Is there a maximum size to the bootlogo file, I have a spica as well and many people have bricked there spica if they flash a bootlogo bigger than 192 kb as it results in overwriting the Bootloader or something like that.
PS:- The bricks are hard bricks.

Hi,
If you create the file correctly, if will always be the same size (1036820), it's not like other android logos (initlogo.rle) that are rle compressed. there is the header and a raw 565 format image, that's it.
For an initlogo.rle you would use ./rgb2565 -rle < logo.raw > temp.bin.
Cheers!
^^ thanks a lot.
thanks 4 this, finally got it!!!

My bad.
Didn't catch that part in the zoomquilt thread.
Edit:
This worked like a charm too!
Something I threw together as a test.
Left a black strip up top so I could see boot messages.
The preview below looks like garbage compared to how it looks on the phone.
I have tried all this wpa_supplicant files to fix ad-hoc connection on my gsi9001, but every time it is hanging on the obtaining ip. Please someone help me with trying on other roms to manage ad-hoc mod. correctly i have used I9001XXKP4 with cranium mod...

these are modules?
2-of them are zip installation and one is just wpa_supplicant module... the all meaning is to change wpa_supplicant module to see ad-hoc connections...

works this without hangign at obtaining ip ?
Actually it's hanging... but after restarting wifi i'ts getting connected...
I´m having some issues too with connection.
I use Crybernation, before always worked with other ROMs, but now it hangs on getting IP...
I changed scan_interval to 0 too, but nothing happens.
Those files are for? Just change them from mine?
Thanks!
ok now it's working simplest way to get ad hoc running is the ad hoc enabler app from the market
http://www.youtube.com/watch?v=MtqiHcC0x5E
First u need to have superuser and busybox installed
Then download "WiFi Ad Hoc enabler" from market and instal it
Open it and goto settings,tick for disable comparibility check
and then click on 1)Verify Prerequisites
it will ask for superuser permission click Allow
Then click on 2)enable adhoc wifi
it will ask u to restart wifi

Good morning.
I have also SGS Plus (I9001) with Gingerbread. XXKPS (Android 2.3.6) and Kernel 2.6.35.7-perf [email protected]#1.
I have also "WiFi Ad Hoc enabler" Ver. 1.8.3.
My problem is this:
I have an internet connection on my Netbook HP mini (internet key USB H3G Italian provider) and an DHCP method for IP adress my LAN (192.168.0.40 to 192.168.0.50, gateway 192.168.0.1 and subnet mask 255.255.255.0)
I share with an adhoc connection to another Laptop HP with Win 7 64 bits, and it work very well
I share my internet connection from my laptop with Windows XP by WIFI to my laptop Win7.
When i tried to connect my android on this lan, i see the connection, after try to connect and the windows XP PC crashed any time.
I didn' understand the reason of this crash.
If i connect first the Android phone and after the win7 laptop, all is good and i have a very fast connection (adhoc by DHCP)
If i connect first the Win7 laptop and after the android phone, the windows XP netbook crashed.
Can you please give me some indication ?
Important. i didn't have on my "WiFi Ad Hoc enabler" the settigs page, only the "about" page with information on the program.
Thanks in advance for your answers
Ask Microsoft why it happens...?
Sent from my GT-I9001 using XDA App
Hey, how to connect my phone to ad hoc? Im currently used BroodROM RC5 btw. Before this, i've tried wifi ad hoc enabler 1.8.4 but i got an error about ownership of supplicant.conf. I appreciate any help in thi9s regard.
-corrupt1234
as kj6 is supposed to bring some bug fixes, I thought I'd check the kernel source.
there's not a huge amount of difference, but some looks interesting, hopefully of use to anyone wanting to building it.

Is there a new kernel source?
Sent from my GT-I9100
yes, kj6 is up,
the diffs are between kj4 and that kj6
to show the file differences (there's also some docs changes but they aren't really needed)

Where did you get the kernel source?
https://opensource.samsung.com/index.jsp
search for N7000
I presume the kkx build will be there under the other device code.

Maybe that diff solves my screen issue.
Just to explain, sometimes my screen does not wake up even if the phone is still running (long pressing the on/off button makes the phone vibrate which means that it is still working) and when I hard reboot it (8 seconds long on/off button press), it restarts and in the battery usage I can see that the phone has been awake for a long time instead of having been idle (when it happens, it is generally during the night).
As I am facing it globally (with both European stock and Hong Kong ROMs), I hope this kernel change corrects it.

I've seen the same thing a couple of times. Still haven't tested the KJ6 kernel to see the effect of those patches yet.
Actually thats spurred me onto testing the KJ6.. Initialtesting suggests Screen powers back up Much quicker from standby
KJ6, where did you get it?
Edit: I have Baseband version N7000XXKJ6 but Kernel N7000ZSKK1. Is is this version you are talking about?

no there's threads with the kj6 kernel, including the CF root thread.
I've just built kernel with the patches, working well so far.
Basically, what you did is you installed KJ6 kernel, rooted it and install the kernel you built?
If yes, do you mind, allowing me to download the kernel you built in order to use it?
Yes. it's me again asking for help about another assignment...

Hello,
I was hoping I could help port a custom recovery to the x86 platform, but I ran into a problem pretty early...:
I have extracted the boot and recovery partitionen images like this:
Code:
# cat /proc/partitions
major minor #blocks name alias
179 0 7766016 mmcblk0 (null)
179 1 11264 mmcblk0p1 bos

179 4 1024 mmcblk0p4 logo
179 5 11264 mmcblk0p5 boot
179 6 11264 mmcblk0p6 recovery
179 7 128 mmcblk0p7 cid
179 8 2048 mmcblk0p8 sp
179 9 8192 mmcblk0p9 panic

179 14 1000000 mmcblk1p2
179 15 31435 mmcblk1p3
# cat /dev/block/mmcblk0p6 > /external1/recovery.img
# cat /dev/block/mmcblk0p5 > /external1/boot.img
But I get the following message when I try to extract the recovery's ramdisk:
Code:
$ ./split_bootimg.pl recovery.img
Android Magic not found in recovery.img. Giving up.
I haven't had this problem before. Is it happening because the differences between the x86 and ARM images is too different?
Thanks!
EDIT:
I have extracted the kernel and ramdisk from the recovery.img using a Hex Editor. You'll find a link to the files below:
dl.dropbox.com/u/19117372/recovery_files.zip
That's what the theory is. Its stopping us from using the kernel source and making a custom recovery because we cannot unpack or pack them.

Apparently the script I used looks for this string: "ANDROID!" in the beginning of the binary file. But this image starts with "init=/init". Is there any other Android devices that does this?
I've downloaded the Android x86 ics source code from Intel and they use the standard:
Code:
#define BOOT_MAGIC "ANDROID!"
When packing the img.

It would be better to look at the other Intel Android Devices like the Orange San Diego and see what their images are. The Android x86 project doesn't even pack the boot.img from when I used it, but maybe I'm remembering wrong.

I've been able to unpack and repack the boot.img using a hex editor (same way we got insecure boot in the first place) and am able to manipulate the contents of the ramdisk, but have not been able to compile a recovery for Intel. As for the standard tools/scripts, I don't think they're capable of dealing with the second stage which is optional in the img format but used by the Razr i (http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack%2C_Edit%2C_and_Re-Pack_Boot_Images).

I think our best bet right now is to hope Motorola can give us documentation on this when the new MotoDev.com comes on November 1st. No device has really been in this position before, so the current tools and documentation aren't helpful. I appreciate you taking a look.

Found this in the sourceforge under system_core.tar.gz:
Maybe helpful...maybe not. The tools could be in the sourceforge.

Hey guys currently trying it too, because i realy need my lovely cwm
when i open the boot.img i see this:
androidboot.bootmedia=sdcard
so if i theoretically would change that to external1
would it boot from my sdcard?!
