New jpeg boot logo size 480x800 (preferably less than 64k.. I flashed a 65k one and it booted fine though... just be careful)
Enter download mode
Flash hacked param.lfs IN HEIMDALL IN THE BOX THAT SAYS PARAM.LFS, NOT FACTORYFS
Reboot normally, if it boots into recovery just reboot again
Ignore garbled text on bootup
Copy your new bootlogo to /sdcard/logo.jpg
Open ADB shell
Enter these commands:
mount -o remount,rw /dev/block/stl6 /mnt/.lfs
cp /sdcard/logo.jpg /mnt/.lfs/logo.jpg
Reboot and enjoy!
Download mode might not show the download mode logo. It doesn't show on mine. Still works though.
In order to flash another logo, you have to re-flash the hacked param.lfs and then copy the new logo.
In order to flash completely back to stock, flash this param.lfs HERE
Some older devices still remain very popular. Phones like theHTC Desire, Sony Ericsson … more
