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:

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'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.
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 2 11264 mmcblk0p2 bosbackup
179 3 1024 mmcblk0p3 ulogo
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 10 512 mmcblk0p10 devtree
179 11 512 mmcblk0p11 devtreeBackup
259 0 8192 mmcblk0p12 pds
259 1 512 mmcblk0p13 misc
259 2 655360 mmcblk0p14 cache
259 3 153600 mmcblk0p15 cdrom
259 4 1253376 mmcblk0p16 system
259 5 5599471 mmcblk0p17 userdata
179 12 3872256 mmcblk1 (null)
179 13 2840820 mmcblk1p1
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.

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.

Great! - Would you mind sharing how you did it?

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?!
I am struggling a bit with the LED brightness.
in
Code:
drivers/leds/leds-bd2802.c
i have the following code
Code:
#define BD2802_CURRENT_WHITE_PEAK 0x5 /* 18mA */
#define BD2802_CURRENT_WHITE_MAX 0x01c /* 5.6mA */
#define BD2802_CURRENT_BLUE_MAX 0x01c /* 5.6mA */
#define BD2802_CURRENT_WHITE_MIN 0x03 /* 0.6mA */
#define BD2802_CURRENT_BLUE_MIN 0x03 /* 0.6mA */
#define BD2802_CURRENT_000 0x00 /* 0.0mA */
What i would like to know, how do i know, which hex value equals which mA value?
i tried googling but didnt find anything.
is there any chart / table to calculate between the hex and mA value?
Thank you
Goodmorning, I've tried to implement the method that request permission first and than execute something but without success ...
Here is my MainActivity code:
Code:
public class MainActivity extends AppCompatActivity {
public static String latitudineCorrente = ""; //current Latitude
public static String longitudineCorrente = ""; //current Longitude
private SharedPreferences sharedPreferences; //shared preferences
private SharedPreferences.Editor mEditor; // shared preferences editor
/* Variable for getting location */
private FusedLocationProviderClient fusedLocationProviderClient;
private LocationRequest locationRequest;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String appLanguage = "ita";
LanguageUtil.setAppLanguage(getApplicationContext(), appLanguage);
/* .... other code.... */
sharedPreferences = this.getSharedPreferences("appname", MODE_PRIVATE);
mEditor = sharedPreferences.edit(); // set edit sharedpreferences
richiamaPermessi(); //permission request
requestLocationUpdates(); // function requestlocationupdates();
CaricamentoInizialeApplicazione(); // function for presetting configurations
}
private void CaricamentoInizialeApplicazione() {
boolean configIniziale = sharedPreferences.getBoolean("configurazioneinizialeok", false);
if(!configIniziale)
{
/* can't execute this because Double.parseDouble(this.latitudineCorrente), Double.parseDouble(this.longitudineCorrente) */
ApiMarkers.getMarkers(MainActivity.this, 0, 400,
Double.parseDouble(this.latitudineCorrente), Double.parseDouble(this.longitudineCorrente),
0, 0,0,1, 0,0,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
/* response elaborations */
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
dialog.dismiss();
Toast.makeText(MainActivity.this, "" + error.getMessage(), Toast.LENGTH_LONG).show();
error.printStackTrace();
}
});
mEditor.putBoolean("configurazioneinizialeok", true);
mEditor.commit();
}
}
/* Function for requist location updates */
public void requestLocationUpdates() {
if(ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) ==
PermissionChecker.PERMISSION_GRANTED && ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) ==
PermissionChecker.PERMISSION_GRANTED) {
fusedLocationProviderClient = new FusedLocationProviderClient(this);
locationRequest = new LocationRequest();
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
locationRequest.setFastestInterval(1500);
locationRequest.setInterval(3000);
fusedLocationProviderClient.requestLocationUpdates(locationRequest, new LocationCallback() {

}
}, getMainLooper());
} else richiamaPermessi();
}
/* Function for requesting access */
public void richiamaPermessi()
{
Permissions.check(this, new String[] { Manifest.permission.ACCESS_COARSE_LOCATION,
Manifest.permission.ACCESS_FINE_LOCATION},
"Permessi di locazione obbligatori per determinare la propria posizione!",
new Permissions.Options().setSettingsDialogTitle("Avviso").setRationaleDialogTitle("Permessi locazione"),

}
@Override
public void onDenied(Context context, ArrayList<String> deniedPermissions) {
super.onDenied(context, deniedPermissions);
richiamaPermessi();
}
});
}
}
The problem is executing function ApiMarkers.getMarkers(.... with latitude and longitude filled ...) but can't execute because latitude and longitude are not loaded... I spent two nights without solution Thanks for any help! Cristian
Up! I tried to follow this video on youtube youtube.com/watch?v=gEcFf2Mv4L0 and in any case I could not understand where or when I can call the method "CaricamentoInizialeApplicazione ()" in order to call a method that uses the location coordinates! What I want is to make sure that I don't call the method already said until the location coordinates are loaded into the variables indicated in the code! Is it possible that someone is not able to solve the problem? Thank you
Oh thanks for any help!
