I didn't know that synapse downloads that zip too. Anyway... i downloaded it manually and moved on with installation. Again the recovery doesn't get flashed it seems. Not from romswitcher or synapse. if i want to boot into recovery (using 3 button combo or power menu from rom) it tries to boot into recovery (blue recovery booting message in bootloader) vibrates 2 times and reboot into rom.

Is that downloaded zip the recovery? i will make a flashable zip for it and flash it in twrp or something. it contains second.img but im not sure if this is a recovery
EDIT2: i flashed second.img using another method and booted into recovery. I get thesame problem while i am sure it was flashed. So it seems that recovery crashes in some way.

No the zip is just a boot,img
and no synapse doesn't download the recovery because it comes with the kernel

ok, then i don't know what happens: or the recovery doesn't get flashed, or it refuses to run.

Hi,
Started all over:
-restored nandroid
-removed all romswitcher directories from sd card
-flashed 0.9
-updated Synapse to the latest version and made sure it has root
-clicked "install recovery" in Synapse and got an empty toast mesaage.
-rebooted to recovery
TWRP was still there. I tried this a few times.

Hi,
I wonder: the zip of the kernel is about 9Mb and it should contain a recovery too (there certainly isn't an image inside). Isn't that too small? Philz and twrp are zips of 7 to 8 MB so the kernel is only 1mb? Just thinking why i can't get synapse to flash the recovery

Hi,
Tried numerous times to flash the recovery now. I never succeeded. It stays with twrp (still haven't used romswitcher). I wonder if ther's somethings with my partitions

no
Update is here!
Now we reached 1.0 that doesn't mean it's stable, but almost everything is working pretty well (kernel side).

installed it right away. I i want to flash recovery in Synapse theres an error mentioned now:
Res/synapse/actions//rs[12]:syntax error: 'newline' unexpected
looks like I derped something
typ in terminal
su
mount -o rw,remount /
sed 's|;;=|;;|g' -i /res/synapse/actions/rs
then try it again
Not sure if this kernel will work on the i527m mega, but i wanted to stop by and say keep up the awesome work Grarak on this project you have, and i gave you thanks in your first post. :good:

30GraKernel
This kernel only supports i920x variants! TW 4.4 and AOSP 4.4
Welcome to GraKernel! I am horrible in naming things, so I just take the first 3 letters of my name and combine it with kernel.
I won't include useless feature to this kernel, only features which give the users proper benefits. Currently I am trying to give the users a balance of performance and battery life, so don't expect this kernel will make your phone faster than other ones. This kernel is made for daily usage!
Most of the features I will port from the msm8960 platform (i9505).
The kernel comes with Synapse. You will find all advanced settings in it.

Samsung6How to use kernel features
This kernel comes with Synapse. Synapse has been written by @AndreiLux. The App works with JSON which will generate from UCI (Universal Configuration Interface). So it is possbile to add an interface for a specific kernel. After installing the kernel you will find Synapse in your App Drawer.
Kexec hardboot
Code:kexec --load-hardboot zImage --initrd=ramdisk.gz --mem-min=0x85000000 --command-line="$(cat /proc/cmdline)" kexec -e - boot multiple roms on your phone
