Yea! Using a modified PhilZ Touch recovery, backup 1st ROM and then restore it to 2nd ROM really works! :good: Now I need a good AROMA coder to help me:

1. Create system.img for stock Samsung ROM (~1.4GB)

2. Create system.img for CyanogenMod/CyanogenMod based ROM (~430MB)

3. Delete 2nd ROM

4. etc (based on gokhanmoral's recovery functions)

EDIT: 2nd ROM factory data reset and flash CM nightly (directly reflash NEXT is a must) works! 1st ROM untouched :D
[Galaxy Tab 2 7" Android Development] yomiguy:
Excuse me ketut! For those like me who only use one Rom... we can use your last single kernel as I have done till now, can't we? I mean, just flash it after updating every nightly of cm 10.1 Rom, and that's all...

Because I don't understand pretty well your last developments and my tablet has been working perfectly just flashing cm updates and your kernel.

So are you going to keep focusing on next kernel with dual boot staff? Or will you keep updating single kernel as well ? :)

Thanks mate!

:o oh! Ok! Sorry for my short knowledge! :p then, which kernel should I use? Or which one is newer? Single kernel or next new kernel? I'm using single one from the first post and its quite good for my tablet with cm ;):thumbup:

UPDATE:

1. Recovery for 2nd ROM - Finished. Based on PhilZ Touch recovery, can be applied in other recovery

2. A little change in kernel installer for better compatibility to 2nd ROM recovery - Finished

3. AROMA based system.img image creator - not started yet :(

Does anyone want to join for the logo, documentation, etc.? Looks like I have to make a new thread for this dual boot system.
[Galaxy Tab 2 7" Android Development] Andrev01:
But we still can have hope for normal (no dual-rom) kernel update? :)
[Galaxy Tab 2 7" Android Development] iroshan:
If you don't have a second Rom installed, you won't feel any difference. Ketut's kernel can identify it!

[Galaxy Tab 2 7" Android Development] Dexxmor:
You can us this kernel for a normal "non dualboot" ROM, there is no need to have a dualboot ROM, if you don't want it. I Use the dualboot Kernel with only one ROM.
[Galaxy Tab 2 7" Android Development] Andrev01:
So now this is the newest and best version of kernel, and only this version will be developed now?
[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
I never made a claim the results of my work is the best, just try my best for my device and shared it.
[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
Although your main operating system is CyanogenMod, I suggest to make it as the 2nd ROM because CM require less space for system.img than stock Samsung: ~430MB vs ~1.4GB :( With a modified recovery, you can update the 2nd ROM anytime. 430MB is more than enough for CM, 100MB larger than CM need.
[Galaxy Tab 2 7" Android Development] iroshan:
And what you provide its the best.:D

http://xdaforums.com/showpost.php?p=41403419&postcount=169 Now PhilZ Touch 5.03.0 P31xx has the capability to handle 2nd ROM :p

I assume your 2nd ROM is CM/CM based, I will explain how to update it to newer version:

1. Reboot into recovery, select "Secondary Recovery"

2. Update your ROM

3. Reflash blackhawk's NEXT kernel

The latest step very important or you will lost your dual boot environment or totally fail to boot if your 1st ROM is Sammy/Sammy based ROM. Hi, I started to use Sammy term ;)

[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
My dual boot tool ready to upload, but just confused what a good name for it :( It's AROMA based tool, any idea?

- AROMA 2nd ROM tool

- AROMA 2nd ROM utility

- blackhawk 2nd ROM tool

- blackhawk NEXT tool

- ...

I named the kernel part as blackhawk-next, this is a temporary name, in developtment code name. I will change "next" to "kernel-1.0" or other. My kernel version number always started by zero because I have a future plan, inspired by gokhanmoral - dual boot kernel! This is a free implementation of gokhanmoral's dual boot method. Following his rule in different way :D Using a lot of resource around here: hard modified gokhanmoral's script, AROMA from amarullz, PhilZ Touch from Phil3759, etc. Really need brain and time, and a good finger to quit from a boot loop :D

Well everything is working as normal. I played about with the rom it is pretty stable. Everything works, and when i fell asleep unlike cm the battery never drained maybe about 3 percent drain overnight which is great. So the battery life on this rom is excellent. You're good to go with your rom. Sorry for the late reply i installed this around midnight. Used the rom and till about 2am and fell asleep. I am still using it. I must say overall it is a great rom. Thank you very much. I've not yet found a fault but maybe i might find one but that would be cm related.

For a beta rom this is really stable. Onlything maybe it isn't a big problem now but in the ota updater lol it doesn't recognize the device as MO.

sentinel rom v 4.5 for gt-i9300

Hello, Sentinel.

First of all I'd like to thank you for this truly amazing rom, there's so many things I can do with my phone and change almost everything I want to within it. I only found 1 issue which may not be an issue at all, I might still be a bit inexperienced with all this modding stuff, but I haven't found a way to overclock or undervolt my phone using your kernel, but I took a risk of using siyah kernel 1.9.1 which is said not to be compatible with 4.2.2 JB and basically all new roms that are out now, but the funny thing is IT DOES WORK! And I think that siyah 1.9.1 kernel and your custom sentinel rom is the best combo ever for my galaxy s3. The battery works great even when I overclock it, it's really stable and never glitching. I can say I'm a heavy consumer, wifi constantly on, and I'm playing psone games with and emulator alot and it still does a pretty decent job. On my next payday I'm definitely donating, buddy. And in a months time when s3 stock 4.2.2 JB will come out, I'd like to see what you can do with that one aswell.

Keep up the great work, best regards, Lietus.
[Galaxy S III General] Sentinel196:
Hi Lietus. I assume you posted this here because you can't post in the ROM thread, so I'll answer you here :)

My official position on over/underclocking and UV/OV is discussed on my website. Have a browse.

Sorry but it's not something I support in my ROMs. People are alwsys welcome to use other Kernels to unlock these features if they want them.

Looking forward to payday :)

Hey, this is my first post, you did a really good job with this rom!

[Galaxy S III General] Lietus:
I understand where you're coming from and I totally agree with you if we users want we can make it ourselves using different kernels especially when your ROM is that great and it accepts different types of kernels. And I've got 5 different types of android machines which could use some improvement so if you're interested and have the time to expand your ROMs through those it would be just awesome. Because your ROM is actually the first custom one I've tried, and after a lot of research I can't seem to trust myself with someone else's :D

Hi Android gurus! I have nut to crack and I was hoping you could help me with that.

I want to use my MK802 IIIS with a projector but I am having aspect ratio/resolution issues. Namely my projector supports 800x600 and 1024x768 but on my Android stick I get chose 1920x1080, 1280x720 or 720x480 (Settings->Display->HDMI modes). The stick has only HDMI output and I am using a cheap chinese adapter to connect it to the projectors vga input. For example with 720x480 I do get the picture but at left side a slice of it is cut off.

Ideal would be if I could set the video output to 1024x768 (with 4:3 aspect ratio).

So, how could I change it?

Is there any Xorg like solution, that is, add resolutions by editing some conf file?

I have limited knowledge on Android but I do know java and I am willing to digg in and so all answers and solutions are welcome. Of course it would be great if there would be easy fix but if you think I should go nuts and create a custom ROM, build custom firmware... I will be excited to hear that. :p
