[Q] My Samsung boot logo disappeared!

First, sorry for my bad English.
I've used ICS REMIX 8.5 ROM before and it has a bug that can't install apps on sdcard, and I've found the solve which flash stock LPB kernel via desktop odin and then flash CF-Root kernel via mobile odin. I do it, then my yellow triangle is gone and my Samsung Logo which at the same page of yellow triangle is also gone
When starting my phone or boot into clockworkmod, it isn't show Samsung Logo anymore (it is a black screen for a while and just skip to boot animation).
After that I have flashed Checkrom V4 via CWM and my Samsung Logo still disappeared. What I can do for this case ?
There are a couple of ways to restore/change the boot logo. If you want to just restore the default boot logo, you can flash the file that's in this post: http://forum.xda-developers.com/showpost.php?p=21678871&postcount=3 (the "restore boot logo" one).
Or, you can download the app mentioned here: http://forum.xda-developers.com/showthread.php?p=21848368&highlight=boot+logo#post21848368 and change the logo to any other image that you want. This would include the default boot logo, of course, though I'm not sure if the app includes the default logo image, or if you would have to find it elsewhere.

Android not booting after changing Boot Logo

Dear XDA Pros
I bricked my Samsung Galaxy A3 (2016), sm-a310f, with changing the Boot Logo. I've tried it before and it worked. I changed it with TWRP again, but i took accidentally a JPG with a higher resolution than my display has. Now it doesnt boot anymore. I tried to go to TWRP, but it doesnt displays anything. After that I tried to flash the Stock Firmware with Odin, but it also doesnt boot/show anything. Can someone help me? Can I flash a (Custom) Rom with Odin? Or a Boot Logo (not Boot Animation!)?
Its a SM-A310F. Sorry for bad english
Regards

Modified BootLogo For E5

This is a modified bootlogo for the Moto E5 to remove the ugly black screen on boot after unlocking your bootloader, The bootlogo included with this is the original BootLogo From the E5 & this doesn't remove "N/A" from the top corner of the screen, this just adds back a bootlogo to overlay the ugly black screen
Bootlogo has only been tested on E5 Play(please report compatibility if you try on normal E5/E5 Plus)
Flashing Instructions:
TWRP: Download the attached logo zip & flash through twrp
Fastboot: Download the attached logo zip, extract "logo.bin" from inside & "fastboot flash logo <logo.bin location>"

When I flashed through fastboot, it did boot the new logo. Its just too small for the plus. The picture stays in the middle of the screen.

This logo.bin works on my e5 play, but the custom images are 480x960, while the default resolution is 720x1280, so the images are too small.
I am able to use this logo.bin as a template with Moto boot logo maker and replace with my own custom images and it works, but using my own stock logo.bin and replacing with custom images still shows a black screen.
Wondering what other modifications you made to enable displaying the logo besides replacing the images?
Thanks again for sharing this!

Very small images in logo, i need 720x1440 images
Hey guys, if your looking for Moto 5e Plus modified bootlogo, here it is.
I used Motorola Boot Logo Maker to modify the logo attached on the first post with one from Moto X resized to 1440*720.
I've done that flash right now on my phone and it's perfectly working, so I'm uploading here for anyone that wish to download and test.
Thanks to the @Dark98 for uploaded the file that I used.
Sorry about my English.
