General :: Tweaking Kernel In Ubuntu To Change Boot Logo For I9300
Apr 29, 2013
I wanted to change the boot logo for i9300. Im well aware that you have to incorporate it in the kernel. I installed Ubuntu, the necessary libraries and brought the cyanogenmod source code. Only part is I dont have the necessary experience to tweak it using the NDK tools
My Samsung Galaxy S3 (GT-I9300) was rebooting itself for the past few days, randomly. Last night, it did it again, but didn't boot back up. Instead, it is now stuck on an infinite boot loop - it gets as far as the splash screen (Galaxy SIII logo), then reboots, on a loop.
I've never tried to flash or root the device, I only used the official OTA updates from Samsung.
The first thing I tried was to remove the battery, SIM card and MicroSD card for 5 minutes. I then wiped the Cache Partition through the Android Recovery Mode. I then flashed using the Samsung Kies recovery procedure. This didn't work. I then tried a Factory Reset through the Android Recovery Mode, multiple times. This also didn't work. The last thing I tried was to flash the ROM using Odin3. I used the firmware version appropriate for my region and carrier. Everything was successful, but I'm still having the same problem.
I tried to view the boot logs with adb, but of course, the phone won't stay on for long enough to establish a USB connection. I'm not sure what else to try.
I came across this on XDA and thought I would post here. Added some stuff so that it was easier than what was said on XDA. As always, do a NAND backup before doing this. I am not responsible if this bricks your phone. I just did it and it worked fine
Things needed:ADB/Fastboot knowledge - HERE also try searching. RGB565Converter v0.3c - Thanks to DeToX-cz! Instructions:Find an or create an image (.png, .bmp, .jpg, or .gif -- 320x480 is preferrable) Open RGB565 Converter Ensure that "To RGB565 (binary)" tab is selected Click "Open Image", select your image Click "Convert to RGB565" (RGB565 Converter will make your image 320x480 if it is not already) CLOSE RGB565 CONVERTER Reboot phone into Fastboot using this command: adb reboot bootloader OR Button combo: SEND/CALL + END/POWER Flash image using this command: fastboot flash splash1 <your_image_name>.rgb565 Reboot phone using this command: fastboot reboot OR fastboot oem powerdown if not then remove your battery View the benefits of your hard work.
I didnt create this. Thanks to sickbox over at XDA for figuring this out and sharing the knowledge with all of us.

I used the jpg that he put since I couldnt find any that looked as nice as his did after converting
Instead of seeing the boring old Android logo or my service provider's logo, I'd love to see the standard text-based Linux boot screen that shows the status of all the hardware and configuration info as my phone boots. My current phone is an HTC EVO 3D running Cool ICS with Sense 3.6 and Revolutionary CWM.
I spoofed my device S6312 to galaxy nexus using network spoofer to download an incompatible game from google play store.According to network spoofer everything worked great but nothing actually happened and that game was still incompatible on play store.So I launched network spoofer and told it to recover my device again to S6102.It said that the device will reboot so I gave it permissions and my device started rebooting but it stop at the Samsung logo and was doing the same thing again and again so s actually boot looping. How to recover my device and any way to do it without a computer.
My Sharp FX (ADS1) is stuck at the "Sharp" logo when I try turning it on, now I know that are several of these post on this forum, but I still can't find any that offers a solution for me. The phone is rooted and that's it, I haven't had time to put a new ROM or anything yet (although I would love to) and I can't seem to get into any type of recovery mode, and I think I have tried all of the button combinations, the only time that I can get it to show something other than "sharp" is when I plug it in, it shows a charging battery.
I have rooted my device and then downloaded CWM and tried to install Cyanogen Mod, I have tried this before and it just rebooted with nothing happening. This time the device would not boot past the motorola logo. I took out the battery and attempted to boot but again the device got stuck at the moto logo.
yesterday, I flashed Modaco Switch for HTC One when my battery is low (20%). Now it wont let me pass the "HTC quietly brilliant" screen. I've searched the solution for hours and still, no luck on finding it out. But I see some thread that suggest me to download a new rom and put it in my SD Card, but I cant even pass the HTC boot up screen. Btw, I've relocked and unrooted my device.
Recently I flashed to this ROM [URL] .... from a stock ROM. Have done it a few times before and no problems have occurred. It's an MIUI rom and I decided to customize the theme a little. The themes section allows to change most of the detail ie fonts, status bar, home screen, lock screen, icons, boot animation.
And that's where it started, when I changed the boot animation, instead of using the default one. When I did a reboot after the switch, the usual boot logo was up, but then the screen turned pixelated like a CRT monitor/damaged LCD screen with colourful pixels. But then in boot into the new animation all fine, and has been ok since. The device boots fine, but I'm worried about that pixelated screen.
I was trying to update my s4 clone, but missed click using something called mcm or something and it restore my cellphone to factory data, and know i dont have boot animation logo, i tried to use many programs like boot animation logo changer, rom toolbox but nothing works.
I Have Xolo A500s android 4.2, Ram 512mb, GPU Mali400mp, 4Inch. i m gaming boy so for playing 3d n hd games in this phone i root it after root i install chainfire 3d pro n open click install tap and phone going restart phone ok after that Phone Is stuck Xolo Logo.
