Freezing at AT&T Logo splash screen during boot.

Every once in a while my phone restarts and freezes at the AT&T Logo splash screen after the Samsung logo. There's no way to get past this besides booting up as if I was about to install a custom rom (holding power, home, and dwn volume) and then canceling and rebooting and even then this only works half the time. Removing battery and rebooting never works. I can't even restart my phone without going through all these loops just to get it on and usable. Anyone know what the issue is? Some people mentioned re installing the kernal. No idea what that means.

[HELP] G920I Stuck at splash screen

Hi! I am on Xtresolite ROM & arter's amazing kernel..
Today I was using my phone normally and had not tweaked anything.. All of a sudden, it started getting stuck at various occasions.. I restarted my phone.. It was still running slow and it had a persistent message of "Unfortunately SHealth stopped working". I managed to disable the app and it seemed to work fine.. After a while it got stuck again and I tried to restart and ever since it has been stuck on Samsung splash screen..
I tried wiping cache/dalvik, disabling xposed but nothing seems to respond..
Any help is appreciated.

Boot Splash

Is it possible to flash the Android bootanimation? Does anyone have that file 4 flashing via twrp?

I don't like Samsungs intro, i did change it on my Note 4.. just dont know which zip i used..
Maybe some have the new Android M bootanimation? 😊

Galaxy Tab Pro Splash Screen Problem

I was playing around with my Tablet. Being a mad scientist trying to get root working on 5.1.1 and I did something that messed up the First boot screen that says. Samsung Galaxy Tab Pro. Well its not there any more just a crazy screen lol Some times its a whiteish screen like static some times I swear it was my desktop after it boots up. The tablet boots up just fine. But the First Splash screen is toast. Anyone know the way to fix that?

EDIT: I have tried reflashing the whole 5.1.1 update with ODIN and still the first boot screen is bonkers.

S4 stuck on red Verizon splash screen. No recovery.

I had a 5.0.1 ROM installed on the stock slot on safestrap. The phone worked but I could no longer go into safestrap to change the ROM so I tried to flash a stock ROM with Odin. I flashed I545VRUFNC5_I545VZWFNC5_I545VRUFNC5_HOME.tar.md5 but now there is no recovery and it gets stuck in the red Verizon splash screen. Any help is appreciated!

[MOD][CM12][COLOROS 2][HYDROGEN OS] Splash Screen Image Injector v1.2

This is untested on the oneplus 2, however I've looked at the logo.bin from your firmware and it is identical to the newer oneplus one logo.bin. Let me know! Thanks!
This is a program that I wrote to decode the newer style "logo.bin" files used in some OPPO, and OnePlus devices. Please read below so you can better understand this type of encoding being used:

What Is A Raw Image?

A raw image, whether it be a file or an image in memory, is simply pixel data. There is no extra information like width, height, name, end of line... Absolutely nothing, just pixel data. If you have an image that is raw and the resolution is 1080x1920 and you are using a typical RGB24 or BGR24 (like the ones used here), then your exact filesize or size in memory will be 1080x1920x3! We use 3 here because there is one byte for the R or red component, one for the G (green), and one for the B(blue).

What Is A Run Length Encoded Image?

A run length image encoding uses a count ;usually a single byte (char), 2 bytes (short int), or 4 bytes (long int); and then the pixel components. So instead of writing out 300 bytes of '0's to make a line of 100 black pixels. Black is RGB(0,0,0). You could encode this as 100, 0, 0, 0. And only use 4 bytes of data to get the exact same image as the 300 byte raw image. All the run length encoding I've found, except the Motorola style which is a little different, use a run length encoding that is pixel-oriented like this.

Now I've figured out this new one and it is a byte-oriented run length encoding. This is for runs of bytes, not pixels. You may think, well whats the big deal? When you add a little area of color, you increase the run length encoded image in you logo.bin immensely! You use 6 bytes per pixel if there aren't any runs of color data. If you had an image that was a 1080x1920 black image with a 25 pixel wide, by 25 pixel high red box in the middle. The encoder would be doing runs of black data efficiently until it reached the red area.
.....0 255 0 255 0 255 0 255 0 255 0 133 /// we've reached the top left corner of the red square /// 13 1 30 1 255 1 // << that was just one red pixel!! in bgr color order (13, 30, 255) <<// And it keeps going through the rest of the red pixels on that line using 6 bytes per pixel, which is the opposite of compression. Before reaching the red square the encoding was decoding to 255 zeros over and over, until finally 133 zeros. 255 zeros is 85 black pixels stored in just 2 bytes!

This type of encoding is only good for grey scale images. It is not good with color, but it still will handle color of course. In grey scale, the Red, Blue, and Green data components are always the same values. All the way from black (0,0,0) to white (255, 255, 255); including every shade of grey in between>>>(1,1,1) (2,2,2) (3,3,3)....(243, 243, 243) (244, 244, 244)<<<

One other difference in this method of run length encoding is that the color byte is before the count, which is backwards from all of the other methods.

The attachment contains the C source code (which is also in the 2nd post) and the executable that was compiled using mingw32 on a 64 bit Windows 7 pc. The png library that I used is LodePng, the source is in the download.

To use logoinjector:

Decode your logo.bin:

Code:

---

logoInjector.exe -i logo.bin -d

---

All the PNG 's will be extracted from logo.bin. Edit the PNGs that you want to change...

Note:
Your original "logo.bin" file is never changed, it is just read. If the file you try to load isn't a logo.bin file, or if it is the older style, then the program will tell you and exit

Inject the image(s) back in to the logo.bin:

Code:

---

logoinjector.exe -i logo.bin -j image_name_1 image_name_3

---

To list whats in your logo file:

Code:

---

logoinjector.exe -i logo.bin -l

---

For a more detailed list:

Code:

---

logoinjector.exe -i logo.bin -L

---

If the colors are messed up use the "-s" switch while decoding.

Code:

---

logoinjector.exe -i logo.bin -d -s

---

If you had to use the "-s" switch to decode properly, you'll have to use it to inject also:

Code:

---

logoinjector.exe -i logo.bin -j image_name -s

---

Note:
With version 1.2, you can put as many names after "-j" as you want, and it's not case sensitive. You also don't have to put the whole name. If you just put "-j fhd" every image in the logo.bin that starts with "fhd" will be injected. There has to be a PNG with the name in the directory though

The size of your modified.logo.bin will displayed along with the original size, if everything went good. Please know the size of you logo partition. I made this program to encompass any device using this format, and there is no set size of the logo partition between devices. Fastboot will just error out if you try to flash data bigger than the partition before it writes anything. But if someone gets brave and trys to "DD" to the logo partition, it could get ugly.:cyclops:

Flash the "modified.logo.bin" file through fastboot.

v1.2

• made it possible for multiple injections in one command


• doesn't add png to the decoded png if it was already in the name


• fixed out of scope with image 26 in OPPO find 7 logo.bin


• added LodePng source in the download


• made the default color order BGR


• displays the modified logo file size as well as the original file size


• runs the modified.logo.bin back through the list function after injecting


• checks the number of offsets between the original and modified logo.bin

Use this at your own risk.
Always make backups.
Always.
