Ok will take a look

Bte forgot to say

I have the device but touchscreen is broken so I cannot check the functionalities

I only can check whether the device is booting
[Samsung Galaxy Mega] kipue:
Ok, well, you'll get reports here :)

For now I feel like I get noticeably better perfs in the games I tried.

Some of them I haven't played since flashing Slim, so it could be it.

Maybe someone else can try and confirm if that's not just my imagination?
[Samsung Galaxy Mega] yusopa:
Thank grarak already test. But i think your kernel make device likely lost root. Like kipue said. I on CM
[Samsung Galaxy Mega] gilbertvpuen:
Had a bootloop after flashing this via philz cwm touch. Im in cm11..
[Samsung Galaxy Mega] yusopa:
I on CM too. No bootloop bro. And i use philz too
[Samsung Galaxy Mega] Kid_Ding:
i'm on cm too. no bootloop and using philz cwm. i also lost root.

either way nice kernel
[Samsung Galaxy Mega] kipue:
You can fix the root by using one of the methods here (flashing a zip or from market), it's what I did.

Haven't tested the battery life yet, but for now, that kernel seem worth using :)

Running fine with AOKP......someone post your voltage settings I'd like to take a look.
[Samsung Galaxy Mega] Grarak:
it has nothing to do with permissions

all roms after 16.01 don't have wifi because of the ML2 source. With the ML2 source it's not possbile to use the wlan module anymore, it has to build in the kernel itself. But without the module wifi won't work for all roms before 16.01. I've decided to keep the wifi module to support more roms. But I guess it's time to fix that. So kindly ask silesh to update his roms.
[Samsung Galaxy Mega] shazzl:
oh try use kairi_zeroblade kernel source work on CML1 base band
[Samsung Galaxy Mega] Droidphilev:
hi,

[MENTION=4551757]Silesh.Nair[/MENTION]: so it seems according to Grarak that we need to ask you. Any way you can fix this please? It would be soooo nice to have this kernel fully working and that we can multiboot all the nice stuff that you make.

Thanks!!!
[Samsung Galaxy Mega] Grarak:
So update is here.

This one is pretty huge. Checkout changelog and github source.

Now we have support for Synapse (more informations in the third post). Thanks [MENTION=4167023]AndreiLux[/MENTION] for the App!

BTW: Wifi will only work for roms after 16.01.2014
[Samsung Galaxy Mega] Droidphilev:
i run latest liquidsmooth. i think 1 day old. let's pray

---------- Post added at 03:02 PM ---------- Previous post was at 02:56 PM ----------

Hi,

Wifi works!!! many many MANY thanks! finally i can start multibooting. One last question about that Grarak:

Can you explain in short how app sharing works in multiboot?

Thanks

Hi,

[MENTION=4443334]Grarak[/MENTION]: i can"t get my phone to boot into multiboot recovery without flashing it. Is this a bug or not implemented yet?

EDIT: forget the above.

Found something else. i cannot flash a secod rom. to where i need to send recovery log?

forgot to mention: it ends at "loading scripts" after that it says "send me the recovery logs"
[Samsung Galaxy Mega] Droidphilev:
Tried again today, had some time. now i can't flash the recovery anymore. not from synapse, nor from romswitcher
[Samsung Galaxy Mega] Droidphilev:
anyone have a link to the recovery?

i checked everything, latest busybox installed etc etc. i can't get multiboot to work :(
[Samsung Galaxy Mega] Droidphilev:
Hi,

I just did a last, big test. Formatted my phone, flashed only Liquidsmooth, Gapps and Grarak 0.7 (no SuperSu this time as i wanted to rule this out. After boot i installed Romswitcher. I got a message that there was an update so installed that too. I had to choose "install recovery" several times and reboot everytime untill multiboot was actually installed. After recovery was there i tried to install a second rom: LiquidSmooth and to be sure CM11. Even now i got the same error "loading scripts > something went wrong > send me recovery.log".

Also... i checked data/media but there was no secondrom after checking this in romswitcher (i don't know when these directories are made exactly)

Wierd: recovery log shows error about 2 empty folders on my external sd that have nothing todo at all with multiboot (it were 2 folder that contained some word docs earlier)

I'm kinda sure that it's not working.
[Samsung Galaxy Mega] SuleimanI:
Followed all instructionsto set up multiboot but can't get it to work. I go to ROM switcher and try to reboot to ROM switcher recovery but it always just reboots my current ROM. Any help will be much appreciated. Thanks to Garak for the wonderful effort.
[Samsung Galaxy Mega] Grarak:
I've said reboot to rs recovery is broken

install rs recovery and reboot to recovery normally
[Samsung Galaxy Mega] SuleimanI:
Thanks a lot bawse. I probably missed that.

I tried to flash the download.zip file downloaded to the rs folder as I assumed that was the rs recovery but installation aborted.

If its not too much trouble, could you please guide me on how to flash the rs recovery?. Thanks
[Samsung Galaxy Mega] Grarak:
it's in the OP

you should read everything before doing something

you can also download synapse from play store

link in the third post
[Samsung Galaxy Mega] Droidphilev:
Even when i 'install' the recovery i have to reboot to it using 3 button combo. If i use powermenu of my rom. It tries to.boot to recovery but it fails and boots back to rom.

Flashing second rom isnt working either. The recovery tries to update a script in your rom zip but this will fail. Mailed 2 logs about it but no answer yet.
[Samsung Galaxy Mega] Grarak:
Download synapse from play store as I told before and don't ask for download link I posted it in OP

I didn't receive anything from you
[Samsung Galaxy Mega] Droidphilev:
Romswitcher installs the recovery, thats not the problem.

Last week i mailed 2logs to the email address in your profile here (@live.at)
[Samsung Galaxy Mega] Grarak:
try to install a rom from internal storage not from external
[Samsung Galaxy Mega] Droidphilev:
Will try to test later today. Otherwise tomorrow.

Did you find the logs?
[Samsung Galaxy Mega] Grarak:
yes sure

not sure why install from external storage doesn't work, but I think it's not a big problem.
[Samsung Galaxy Mega] Droidphilev:
Hi,

[MENTION=4443334]Grarak[/MENTION]: you were right, flashing went fine from internal sd. but but but:

-It took me nearly 5 times to install recovery (tried both Romswitcher and Synapse). Flashing recovery isn't working well.

-I am VERY sure that i chose not to share apps and data in Romswitcher and flashed second rom in recovery succesfully.

-Booted into second rom using RomSwitcher

-All apps from first rom were there, so i wanted to boot into first rom to check settings about this.

-Tried booting using 1 press powerbutton after vibration which did not work. It kept on booting into seond rom (which was very unstable because apps/data i think)

-Booted into recovery to delete second rom. This didn't work. still booting to second rom + from then on booting to recovery didn't work anymore. If i tried that it tried to boot into recovery but rebooted back to second rom.

-I ended up flashing a recovery with pc to put back a nandroid.

Any ideas please?

EDIT: did a second, small test but had to stop due to work:

-"share app" and "share data" get enabled randomly (after reboot? or is Romswitcher fighting with Synapse?)

-choosing rom using hardware buttons is definately not working. (also i don't have a setting "Manualboot")
[Samsung Galaxy Mega] Grarak:
Synapse does some weird things. I have to remove those options from it.
[Samsung Galaxy Mega] Droidphilev:
Ok, will try everything again later on without installing synapse. Still i think this will not be a solution for the hardware keys not listening at boot, right?

2 questions:

-Do you know the reason why flashing the recovery is hard to do?

-Is the zipfile of a rom that gets flashed to second rom changed permanently? or can it still be used to flash to first rom?

---------- Post added at 11:13 AM ---------- Previous post was at 10:14 AM ----------

Hi,

Installed kernel again. Installed only Romswitcher. The expected problems for falshing recovery were there. Flashed a second rom. Apps and data were not shared :)

As i expected: the hardware button choosing method wasn't wroking. even without Synapse.
[Samsung Galaxy Mega] Grarak:
I've updated the OP

I copied the wrong instructions
[Samsung Galaxy Mega] Droidphilev:
aha!!! lemme try that! :)

---------- Post added at 11:30 AM ---------- Previous post was at 11:20 AM ----------

@Grarak:

Sadly enough it isn't working either. Tried 3 reboots and pressed 2x hardware homebutton every time. It always booted into first.
[Samsung Galaxy Mega] Grarak:
no idea working for me. You have to press the buttons immediately after the vibration
[Samsung Galaxy Mega] Droidphilev:
strange. tried while vibrating, after half a second and after a second. i guess my "rythm" must be bad

---------- Post added at 12:04 PM ---------- Previous post was at 11:40 AM ----------

switching rom s using the app so i wanted to flash a "good" second rom but now there's again the problem as earlier: suddenly i cannot boot into recovery anymore. Not with powermenu of the rom. Not with 3 button combo. I get the blue line "booting into recovery" when bootloader starts but it seems recovery crashes. it reboots to rom on its own
[Samsung Galaxy Mega] Droidphilev:
Hi,

It seems that wifi isn't working for second rom. First time i try this at home. It hangs at "turning on wifi"
[Samsung Galaxy Mega] Grarak:
I didn't find a fix for this yet

BTW:

Update is here. New nice stuff in Synapse! Check out OP for details.

Wifi will only work on roms after 03.02.2014
[Samsung Galaxy Mega] Droidphilev:
Is wifi/second rom working on other machines or is it a global problem.

Thanks for the info! I guess i will have to wait for a new Liquidsmooth build :)
[Samsung Galaxy Mega] Mukiai:
v. 0.8

Thanks fort tout hard good work.

The last version issue here. I'm running last LS. With 0.7 no problem. I've test your last just now. But wifi disappears. I've also lost the back physical button function. And my phone little hot. When i activate synapse, the phone became very very hot.

I've test 0.8 just 10minutes ans i lost 40% of battery.

Then reinstall 0.7 and all works good again.
[Samsung Galaxy Mega] zcink:
Yes WiFi is broken again on 0.8

Using LS ROM.
[Samsung Galaxy Mega] Grarak:
Sometimes I think you guys cannot read
[Samsung Galaxy Mega] zcink:
Huh?

Went back to 0.7 and all is fine.
[Samsung Galaxy Mega] Mukiai:
Why? Because of a report? I know that you wrote about a good wifi for ROM above 03/02, but for phone which is really hot and back button? Maybe just me... Or no... That's why I share my experience. :)
[Samsung Galaxy Mega] Grarak:
You reported wifi issue again that's the reason. May you could use an up to date rom, then the other issues should be solved
[Samsung Galaxy Mega] zcink:
Just wondering

No WiFi before 2/3/2014

Today is 2/4/2014

So the ROM we are using is not up to date unless it was born yesterday?

OK got it.
[Samsung Galaxy Mega] samueldewit:
Hey Grarak,

I don't want to be rude or sound like a huge noob... But where do I find those Synapse settings? :o

I cant see it in my app drawer...

I am on latest SlimKat version and the 0.7 version of ur kernel...

Any help/recommendations would be appreciated.

Kind regards,

Sam
[Samsung Galaxy Mega] Grarak:
Download from play store

I would suggest you to update your rom and flash 0.8

on 0.8 synapse will come with the kernel
[Samsung Galaxy Mega] Droidphilev:
Hi,

Hopefully i have the time today to flash latest Beanstalk and hopefully it is new enough to work with 0.8.
[Samsung Galaxy Mega] samueldewit:
I tried 0.8 but wifi did not work on my build. I wait for the next update then I will update it with the kernel. :) Thanks for the quick reply. Great work!
[Samsung Galaxy Mega] jamaljmys:
thank you for your efforts

iam not good experience in kernels, but could your kernel get these features (DT2W/S2W) since it is based on CM kernel?

thanks again
[Samsung Galaxy Mega] Grarak:
As you know my digitizer is broken I cannot add those things.
[Samsung Galaxy Mega] chayjinn:
need help here, flashed latest slimkat and flash 0.8 grakernel, booted to the rom then suddenly hang and it restarted. i just wan to flash the kernel without synapse and romswitcher. am i doing it wrongly ? pls advice

Anyone???????
[Samsung Galaxy Mega] samueldewit:
Instead of spamming this thread, look around in the other posts and the Q&A section. To answer your question: Yes, you need the recovery image. Put it into the PDA section and flash it.

not a huge one but worth to update

Will .9 fix wifi for extra roms Grarak?
[Samsung Galaxy Mega] Grarak:
Read the changelog
[Samsung Galaxy Mega] Droidphilev:
i did ofcourse but i don't know if that Prima thing has something to do with wifi on second rom. Will try to find out later on if you don't want to answer, np.
[Samsung Galaxy Mega] Droidphilev:
The download at first start of romswitcher goes wrong
[Samsung Galaxy Mega] Grarak:
Use synapse for rom switcher
[Samsung Galaxy Mega] Droidphilev:
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.

---------- Post added at 02:20 PM ---------- Previous post was at 02:14 PM ----------

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.
[Samsung Galaxy Mega] Grarak:
No the zip is just a boot,img

and no synapse doesn't download the recovery because it comes with the kernel
[Samsung Galaxy Mega] Droidphilev:
ok, then i don't know what happens: or the recovery doesn't get flashed, or it refuses to run.

---------- Post added at 03:37 PM ---------- Previous post was at 02:38 PM ----------

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.
[Samsung Galaxy Mega] spoxxx:
I installed rom slimkat 4.4.2 RC2 wanted to try this kernel, but after installing the kernel by CWM when you reboot the phone goes into bootloop and hangs it will be something you can fix it? Maybe I'm doing something wrong?
[Samsung Galaxy Mega] moosiemooses:
Loving it on the sprint mega! Thank you!
[Samsung Galaxy Mega] Droidphilev:
Are you able to flash the recovery?
[Samsung Galaxy Mega] Droidphilev:
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
[Samsung Galaxy Mega] moosiemooses:
Yes
[Samsung Galaxy Mega] Droidphilev:
Did you do it like i wrote in my posting above? or did you do it in another way?
[Samsung Galaxy Mega] Droidphilev:
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 :(
[Samsung Galaxy Mega] i04055:
Hi Grarak, do you have plan to support TW ROMs for multiboot?
[Samsung Galaxy Mega] Grarak:
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).
[Samsung Galaxy Mega] spoxxx:
why not work on ROM slimkat 4.4.2, ?? adds the kernel through cwm after installing the following step is only called bootloop recorvery
[Samsung Galaxy Mega] Droidphilev:
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
[Samsung Galaxy Mega] chayjinn:
anyone pls help ? been asking for few days, but no one is helping at all. anyone can tell me how to install this kernel on the latest slimrom ? highly appreciated. thanks
[Samsung Galaxy Mega] Grarak:
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
[Samsung Galaxy Mega] starmaster10:
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:
[Samsung Galaxy Mega] Droidphilev:
Hi,

Ok... used these commands and this time Synapse showed a toast that xxx bytes were copied etc so i "think" recovery is installed. But again its not working. Not with power menu, not with 3 button combo. It.tries to boot into recovery, vibrates a couple of times and boot back to rom. Thats it.

EDIT: anyone else having problems with latest build and wifi? sometimes it says my network is out of range. reboot sometimes helps
[Samsung Galaxy Mega] shazzl:
Grarak can u help me on dual boot... I want to make tw and asop... is it possible? ?

Sent from my GT-I9205
[Samsung Galaxy Mega] Grarak:
probably no

unless:

1) you make a hybrid kernel between tw and aosp

2) use kexec hardboot

3) switch kernel on every reboot

Updated!

Now flashing recovery through synapse should work.
[Samsung Galaxy Mega] Droidphilev:
I got the popup in Synapse that things are installed. Still not able to boot into the recovery. I tries to but ends with a couple of vibrations and reboots to rom. Back to twrp for now :(
[Samsung Galaxy Mega] yusopa:
I proud on you bro bcoz always try and try. :thumbup: .
[Samsung Galaxy Mega] Droidphilev:
hi,

appart from recovery not working i also still have wifi problems. sometimes all networks are "out of range". no wifi icon either.
[Samsung Galaxy Mega] Grarak:
Updated!

RomSwitcher has been removed, because wifi didn't work on other roms
[Samsung Galaxy Mega] Droidphilev:
This is a real shame. Was truly hoping for dualboot :(
[Samsung Galaxy Mega] shazzl:
Dud it hard I get the wifi on treck...for each rom. A lot of effot and testing have bean done...
[Samsung Galaxy Mega] coverworld:
A shame? Make it by your own better. :mad:

He makes a great job.
[Samsung Galaxy Mega] Droidphilev:
I wasn't saying that the kernel isn't great, was i??? There's nothing wrong with saying that i regret it.
[Samsung Galaxy Mega] Grarak:
I don't think he meant it rude

Maybe romswitcher will come back but first I have to repair my mega
[Samsung Galaxy Mega] Droidphilev:
ah ok. it's not definatelly then. i will pray Grarak :)
[Samsung Galaxy Mega] shazzl:
What's hapen to your mega....
[Samsung Galaxy Mega] Traine:
It's silesh old broken mega but grarak asked silesh to give his broken mega
[Samsung Galaxy Mega] Grarak:
Updated!
[Samsung Galaxy Mega] Droidphilev:
Thanks. I guess it won't work with Liquidsmooth anymore now so i will give it a try later on with a newer rom
[Samsung Galaxy Mega] fleagalbaum:
I just flashed this kernel on my I527m but it just bootlooped before the boot animation.
[Samsung Galaxy Mega] Grarak:

Little one
[Samsung Galaxy Mega] Grarak:
Updated!

You should try the last version, many improvements
[Samsung Galaxy Mega] zcink:
This new kernel works great with RR rom.
[Samsung Galaxy Mega] coverworld:
Thx for your work, runs fine :)
[Samsung Galaxy Mega] chayjinn:
can u guys provide the steps to flash this kernel ? seems like i am the only one can flash this kernel. always get boot loop. dunno wat is going on.
[Samsung Galaxy Mega] zcink:
The kernel only works on KitKat roms

Will not work on TouchWiz roms.

Also what recovery are you using?

I recommend Philz newest touch CWM (6.25 I think)

Obviously just flash the same as you did your rom.

Do have knox bootloader?

Could be causing problem?

Don't know if this helps.

Just took a stab at it.
[Samsung Galaxy Mega] chayjinn:
hey thanks for the reply, just wanna to know how to check whether i have the knox bootloader?
[Samsung Galaxy Mega] Grarak:
Knox bootloader has nothing do to with kernel. Make sure you are using a KitKat Rom which is up to date.
[Samsung Galaxy Mega] Silesh.Nair:
Finally took the plunge today and installed Grakernel. Lots of features compared to the stock kernel. Working well with mokee.

Just wish Grarak sorts out the multiboot issue so that we could use romswitcher!!!
[Samsung Galaxy Mega] chayjinn:
tried to flash on slimkat, stuck on samsung galaxy mega screen. donno whats going on.. .. same goes to mokee as well. just flash using recovery but always cant get into home screen....
[Samsung Galaxy Mega] Silesh.Nair:
I don't know what you are doing wrong, but it works on all the roms i tried. I have attached screenshots of it running in Gummy, Slimkat & CM11. It works on mokee as well. So I guess, it works on all others too.

I used philz recovery latest. Are you running art by any chance?
[Samsung Galaxy Mega] chayjinn:
i used twrp. and using dalvik. maybe i should try philz.

---------- Post added at 01:35 PM ---------- Previous post was at 01:08 PM ----------

tried with philz as well.. wont go to the boot screen stuck on samsung galaxy mega screen.

rom : mokee (latest)

gapps : latest minimal (april from banks)

recovery : philz latest

additional info: silesh, previously do u remember u build those roms with overclocked kernel ? is the same thing happen it right here. i guess i cant use a different kernel. dunno what is going on, tried many ways but still the same.
[Samsung Galaxy Mega] Droidphilev:
+1

It would be nice to have multiboot together with all your work Silesh.Nair
[Samsung Galaxy Mega] yusopa:
Grarak kernel is awesome. Multiboot hope fix in future. By the way i still hope f2fs will work someday.
[Samsung Galaxy Mega] Droidphilev:
Hi,

Updated from 1.4 to 1.5. It boots and whatsapp etc are started but after a while it reboots again. I tried a few things like resseting synapse settings etc but no go.

If you want to try this, make a nandroid. When 1.5 is flashed you cannot go back to 1.4 or stock kernel (tried both). If you do that it hangs at the popup "starting apps".
[Samsung Galaxy Mega] Silesh.Nair:
No such issues for me, yet. Running mokee odexed on art runtime.
[Samsung Galaxy Mega] Droidphilev:
Hi,

Strange, i'm on AOKP since a few days and nothing much is installed. 1.4 works just fine.
[Samsung Galaxy Mega] MiCmAsTa:
Strange, I'm stuck at the Samsung Screen. Prolly due to the CWM version. Will try philz recovery. Will try and update again
[Samsung Galaxy Mega] tranphungan:
sorry, may I know the way to get the original back! I use CM 11 nightly
