Hi guys thanks again for the help with changing my boot splash that thread went epic due to that guide posted

ok so now im still on flexreaper 5.1 EX, BOOTLOADER: V7 ics

v7 supports dual boot right? i know, i know, i have read the thread but i cant actually see much info on this,

I basically want to have 2 roms , my current flex reaper and now to add the jellybean port from randomblame,.

damn that sucks,.... am i missing something? why would i want 2 kernals for one rom? lol cheers for reply anyways.

i think thats what us flashers "hehe" would love the most, able to try new roms without overwriting the current.

You could use it for custom kernel testing if you were a kernel developer (but this can be done even without flashing the kernel at all with fastboot boot command).

The main reason for dualboot in Skrillax_CZ's bootloaders, at least for now, is to allow to boot into Linux distro instead of Android without sacrificing the recovery, as earlier method for dualbooting Linux was to replace recovery image with second OS kernel. With dualboot bootloader you still have recovery and you can select the OS you want to boot.

gotchya i actually yeah see the point test a kernal without making the device unusable unless you nvflash...... im a big duuuh sometimes

@chismay: with modified bootloader you actually can do anything to boot partition without worying that you won't be able to restore it later without nvflash. Modified bootloader gives you fully usable fastboot where you can do some cool operations (all based on latest v8):

To flash any kernel to boot partition (primary kernel - usually for android):

fastboot flash boot boot.img

where boot.img is a file with kernel image with initrd.

To flash secondary kernel you can do

fastboot flash secboot kernel.img

You can of course flash new recovery with:

fastboot flash recovery recovery.img

But most of all, for testing new kernels and recoveries, you can boot any image without flashing into tab:

fastboot boot boot.img

where boot.img is any bootable image in Android format (Android kernel image, Linux kernel image or recovery image). This works by downloading the image into tablet's RAM and the booting it from there.
