[INFO] Details on boot logo format

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.

diffing kj4 - kj6 kernels

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.

to compare against kj4 as 6 is supposed to bring bugfixes..

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?

Java maze solver HELP

I've been working on trying to create a maze solver method using an enum, but it has not been going so well.
This is the enum class:
Code:
public enum Direction {
N, NE, E, SE, S, SW, W, NW, HERE;
/**
* Returns the X/column change on the screen that is associated with
* this direction: -1 for W, 0 for N/S, and +1 for E.
*/
public int getColModifier() {
int mod;
switch (this) {
case NW:
case W:
case SW:
mod = -1;
break;
case NE:
case E:
case SE:
mod = +1;
break;
default:
mod = 0;
break;
}
return mod;
}
/**
* Returns the Y/row change on the screen that is associated with
* this direction: -1 for N, 0 for E/W, and +1 for south.
*/
public int getRowModifier() {
int mod;
switch (this) {
case N:
case NE:
case NW:
mod = -1;
break;
case S:
case SE:
case SW:
mod = +1;
break;
default:
mod = 0;
break;
}
return mod;
}
/** As {@link #getColModifier()} */
public int getXModifier() {
return this.getColModifier();
}
/** As {@link #getRowModifier()} */
public int getYModifier() {
return this.getRowModifier();
}
/**
* Returns the direction that is the opposite of this one.
* For example, <code>Direction.NE.reverse() == Direction.SW</code>.
* (The opposite of HERE is still HERE though.)
*/
public Direction reverse() {
if (this == HERE) {
return this;
}else {
int reversed = (this.ordinal() + 4) % 8;
Direction[] dirs = Direction.values();
return dirs[reversed];
}
}
}
and this is the method that I have been trying to write:
Code:
public java.util.ArrayList<Direction> getPathToExit(){
for (int x=0; x<map.length; x++){
for (int y=0; y<map[x].length; y++){
if (map[x][y]=='S'){
this.startRow=x;
this.startCol=y;
}
}
}
System.out.println("start "+startRow+", "+startCol);
return getPathToExit(this.startRow, this.startCol);
}
private java.util.ArrayList<Direction> getPathToExit(int row, int col){
Direction [] dirs = Direction.values();
ArrayList<Direction> path = new ArrayList<Direction>();
getPathToExit(row, col);
if (row < 0 || col < 0 || row > map.length || col > map[row].length){
return path;
}
else if (map[row][col] != ' '){
return path;
}
else if (map[row][col] == 'E'){
path.add(Direction.HERE);
return path;
}
else {
for (int x=0; x<dirs.length-1; x++){
map[row][col]='x';
int nextRow = row + dirs[x].getRowModifier();
int nextCol = col + dirs[x].getColModifier();
path = getPathToExit(nextRow, nextCol);
}
}
return path;
}
The problem I am having is that I keep getting stackoverflowerrors or the piece does not move (tested this by printing what row/col it is on), it would stay on the same tile then crash.
Thanks in advance.

[TOOL] acHelper | Just small themers Tool | 001 | 29.09.2012

### Description:
I think that almost all themers gets tired when they needs to make resources-redirections file (at /res/xml/ folder).
### How to use it?
- Put themed icons to /acHelper/themed/ folder
- Run /acHelper/run.bat (If you're Linux user - launch achelper.jar by hands)
- Type icons prefix
- Enjoy

[HELP] why Zygisk need to force dlopen /system/bin/app_process

1. Why use android_dlopen_ext in the first_stage_entry function to force open /system/bin/app_process?
2. Why dlclose immediately after dlopen in second_stage_entry? Why do it?
// native/jni/zygisk/entry.cpp
static void first_stage_entry() {
android_logging();
ZLOGD("inject 1st stage\n");
char path[PATH_MAX];
char buf[256];
char *ld = getenv("LD_PRELOAD");
if (char *c = strrchr(ld, ':')) {
*c = '\0';
strlcpy(path, c + 1, sizeof(path));
setenv("LD_PRELOAD", ld, 1); // Restore original LD_PRELOAD
} else {
unsetenv("LD_PRELOAD");
strlcpy(path, ld, sizeof(path));
}
// Force the linker to load the library on top of ourselves, so we do not
// need to unmap the 1st stage library that was loaded with LD_PRELOAD.
int fd = xopen(path, O_RDONLY | O_CLOEXEC);
// Use fd here instead of path to make sure inode is the same as 2nd stage
snprintf(buf, sizeof(buf), "%d", fd);
setenv(MAGISKFD_ENV, buf, 1);
struct stat s{};
xfstat(fd, &s);

// 通过 inode 在 maps 中搜索 /sbin/magisk(app_process) 对应的内存区域
auto [addr, size] = find_map_range(path, s.st_ino);
if (addr && size) {
// 下面使用 android_dlopen_ext 重复加载 /sbin/magisk,
// 通过 reserved_addr 强制覆盖内存.
info.flags |= ANDROID_DLEXT_RESERVED_ADDRESS;
info.reserved_addr = addr;
// The existing address is guaranteed to fit, as 1st stage and 2nd stage
// are exactly the same ELF (same inode). However, the linker could over
// estimate the required size and refuse to dlopen. The estimated size
// is not accurate so size the size to unlimited.
info.reserved_size = -1;
}
setenv(INJECT_ENV_2, "1", 1);
// Force dlopen ourselves to make ourselves dlclose-able.
// After this call, all global variables will be reset.
// 重复加载 /sbin/magisk 到内存, 覆盖之后全局变量将被重置
// 这里为什么要强制 dlopen? 只是为了以后可以使用 dlclose 释放 zygisk 吗????

// 这里的dlopen并不会重新调用 zygisk_init, 这里是假的dlopen? 只是为了下一行的 dlclose?
// 为什么要这样做?
// Why do this?
