Q: I get weird rainbows in recovery and when my device boots? What gives?
A: This is what happens when a Gingerbread or ICS kernel is booted on a device with Froyo bootloaders. You will need to either live with the rainbows (recovery is at least partially usable with the rainbows now) or flash Gingerbread bootloaders. Stay tuned for more info on bootloader flashing.
Unfortunately, the classic "rainbow fix" we used for Gingerbread is not compatible with how video acceleration is set up in ICS. The rainbowfix will just cause the device to crash immediately on boot. (I think this is why jt was not successful with LinuxBozo's CM7 source.)
Q: I'm getting rainbows, how do I flash Gingerbread bootloaders?
Flash the bootloaders from the file attached to this post using Heimdall as follows:
heimdall flash --primary-boot boot.bin --secondary-boot Sbl.bin
DO NOT do this unless you are experiencing rainbows, and DO NOT do this until you have confirmed you can flash less dangerous stuff (like kernels) with Heimdall. If the flash fails you will hardbrick!
Thanks to LinuxBozo for confirming, way back in the days of UCKJ2, that Heimdall can safely flash bootloaders from leaks. http://forum.xda-developers.com/show...4#post18539754
- Be warned, once you do this step there is no going back. For whatever reason the Infuse won't flash dumped bootloaders, so there is no known way to return to Froyo and Rogers Gingerbread bootloaders.
