Boot Logo

[mindlery]

I finally changed the boot logo in my phone. By keeping permissions the same and not extracting the the whole param file... and root because i am lazy.

Take the .zip from the end of the file name and paste the poison simply as PARAM and reboot and enjoy your new green logo. Of course back up original.

Permissions should not be an issue and i attached a screen of the file info i took prior to editing it.

I forgot to say what i used to change the logo.jpg

Linux and xarchiver utility. Extracted and replaced with my image and set permissions. Checked to make sure file size was similar and proper resolution and that's it. Hope to figure a way to flash it soon so i can wreck stuff faster.

Ah... probably should mention to do this NOT on stock ROM or at all. The more i read on it the more stupid it is to mess with this area unless you know what you're doing. I'll leave it up but don't think anyone should try it.

Ok! I hope this is useful because i've been able to change the initial image with perhaps a MUCH safer way.
Using Linux, i installed Heimdall.
I extracted stock ROM within Linux and used Ark to extract what the Mint archive wouldn't.
Already i had prepared my 2220x1080 jpg to 75 kb and simply deleted logo.jpg within param.bin while viewing with Xarchiver. I did not extract the param.bin file. Then i added my logo.jpg and closed up Xarchiver. The new logo.jpg was also set to r--r--r-- before insertion.
Then, with phone plugged in while in download mode (usb enabled prior in dev options and tested of course)... opened up the terminal from the folder containing param.bin and typed:
sudo su
Heimdall flash --PARAM (dragged param.bin into terminal window and hit enter)
Device booted with new image and then into twrp. I figured a cache wipe was needed so i did that and all was good. Would like to know if this is a horrible idea. Just using rooted stock ROM with twrp.
I posted the image... but of course my phone didn't change anything at the bottom. No way.
