lol, yeah my philosophy exactly. This is all fun for me, and just about everybody is helpful. .. Just keep that in mind when it grows to 100+ pages and a guy asks about the importance of the fsck script. .. :p
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
working on some other kernels right now, among them are PBJ, stock, and perseus
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Quick question, actually two...

1. How about possible implementation of Sabre kernel, I can't speak for Ptmr3, but would love to see the kernel working with this mod.

2. As for settings in Trickster, any thoughts on using lower/higher voltages and UC/OC, or are we just shooting for reliability as compared to performance. I'm all for tweaking for performance regardless of possible ill side effects. . Any recommendations for my type, pushing the envelope?
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
I can ask ptmr3 about it. I would rather not implement kernels that have fsync disabled, though. Just one more variable to foster issues. Plus, that kernel has had a history of lock up issues, SODs, other things. Not knocking his work at all, just stating facts. Personally, I would avoid using that kernel myself with this mod because I have had instability issues with it every single time I have used it.

Also, trinity kernel provides the best performance of any kernel I have used on the note II (including asylumcore).

If you guys truly want it, I’ll look into it and talk to pt… but I will not do the testing myself, and be it known now that I am not recommending it.

As far as pushing your device limits with CPU adjustments, the things I mentioned are pretty much everything. IO is busy being enabled will help, the lower sampling rate, etc…

If you want to increase snappiness a bit, bring your up_threshold down to 75-78. That’s about all I can really recommend. The default parameters for the GPU are already dialed in pretty aggressively and good.
[T-Mobile Samsung Galaxy Note II] wbonney4:
This thing is awesome. Just curious is there an actual update or are you just changing the date
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
I changed the date twice so far. Both times because I felt the need for users to see that I had added some vital information to the OP or thread in general - relative to this modification.

I changed the date today, with an "update" because I wanted to encourage people to re-read the OP as it now references the post I made earlier about the CPU adjustments after successfully converting your file systems.
[T-Mobile Samsung Galaxy Note II] Smartassassin:
Will this work with neak?
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Thanks, do you think you'll try to work Trinity into it?
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
Haha, trinity is the one found in the OP bro.

I use two kernels.

Trinity, or PBJ.

But yeah, trinity is the one you are on right now bro if you are using this mod.
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
lol, guess I could have looked, been busy setting my phone after wiping and playing with this Yandex launcher, pretty cool 3d launcher.. Highly recommended! !!:thumbup:
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
Oh. My. Zodd.

Look at IO... rofl

EDIT******

There will be an aroma installer version of this uploaded over the weekend after I make some....... "final touches" to it.

You can thank dwitherell for tossin that one together. Dude is a baws
[T-Mobile Samsung Galaxy Note II] Ducter:
Not sure how you guys are copying the backups off the internal to your pc but I cant do it, unspecified error while trying to copy it. Think its permission based but cant change the permissions of the files.
[T-Mobile Samsung Galaxy Note II] rancidm:
Here is my s4_flare _lightning lock screen. I take no credit to making the zip file , but only making the lighting part of it .

https://dl.dropboxusercontent.com/u/77913498/s4_lightning_lockscreen-blue.zip
[T-Mobile Samsung Galaxy Note II] Ducter:
Just changed the backup location to external, going to see how that goes...

---------- Post added at 01:51 AM ---------- Previous post was at 01:32 AM ----------

Worked fine in doing it that way, now to see if I can see a difference..
[T-Mobile Samsung Galaxy Note II] Ducter:
Oh, not that I think it was being debated but I am on tweaked.
[T-Mobile Samsung Galaxy Note II] bhowanidin:
Would there be any issues from me using this, but not changing to ext2?
[T-Mobile Samsung Galaxy Note II] Kal-El7:
+1 on this. I'm on exFAT and have been needing it for file sizes bigger than 4GB (videos).
[T-Mobile Samsung Galaxy Note II] Ducter:
Just my findings so far, and understand YMMV so it could be worth you trying and perhaps things will settle in a bit better but so far for me this didn't work very well.
[T-Mobile Samsung Galaxy Note II] rancidm:
what kernal can we use that doesnt have the leak in it when it gets fixed ? ?

flash the kernal through recovery like normal or have to redo the whole ext 2 modification with a new kernal ?
[T-Mobile Samsung Galaxy Note II] Ducter:
What's the leak I see referenced in some posts? I haven't seen anything abnormal with the kernel as of yet.
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
I would recommend using those voltage settings either way
[T-Mobile Samsung Galaxy Note II] bhowanidin:
Look forward to this AROMA package. Any info on whether or not it will wipe /data (so I can make appropriate back-ups now)?
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Yes it will wipe data if you chose to go ext2 for your data partition. Make a backup of just your sys / data folders to your ext sd or computer. You can restore them after you repartition..
[T-Mobile Samsung Galaxy Note II] bhowanidin:
I always back up to external (sd card), so I take it I can skip the the whole PC copy-paste-rinse-repeat step?
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Yep,

Only pointed that out because twrp doesn't default backups to the Ext sd card.
[T-Mobile Samsung Galaxy Note II] Kal-El7:
Even on exFAT?
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
What file system you are currently using has nothing to do with your CPU voltages. They don't affect each other. I was saying it would be a good idea to match those voltages as close as possible no matter what kernel you are running or what file system.

As for the aroma installer, it will automatically back up all partitions, wipe them, format them, then restore them and flash the appropriate kernel afterwards. It will be an easy process but I would recommend backing up your internal SD to the computer anyways.

And the aroma installer will back up to external not internal.
[T-Mobile Samsung Galaxy Note II] Kal-El7:
lol....I'm typing and reading all while driving. I meant Bullet kernel....but thank you for the settings. I'll have to give it a go tonight or tomorrow. (I parked just now to type this). lol
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
Looool... Yeah don't type and drive bro. I've had some close calls doing that.

Bullet kernel huh? What build are you on? I didn't think bullet kernel was updated again since like.... Novemever?
[T-Mobile Samsung Galaxy Note II] Kal-El7:
lol....I know, I know haha....98% of those moments are at red lights. In Chicago we have a lot of those.

I know, right? Bullet has been under the radar. But it's been a bliss for me. I overclock, uc and uv easily. With that kernel I average 25+ hours of battery with nearly 50% of screen-time logged, keeping in mind that my personal settings and options are extreme, not for the social-nerd. The most extreme I've pushed once on another ROM was a little over 30 hours with nearly 50% screen-time. That's including scaling down my cores and a bunch of other stuff. But I've been hearing about this Perseus elephant in the room. If it supports exFAT I'll have to give that a try. On Tweaked ROM the kernels Trinity and Peanut Butter and Jelly don't support exFAT. I really didn't realize that until after I flashed those and my SD card did not show up. Bullet has been great for me. I look for overclock-friendly kernels which also support exFAT. I don't see many choices with that combo for the Note 2.
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
Yeah exFAT support is hard to come by. The 64GB cards are better with it formatted to that, however. So it is tough if you have one because it locks you into maybe 1 or 2 options for a kernel (if at all).

When was the last time it was updated, though? I would be interested in modding it up for you to work with this.

Also... I'm uploading the aroma ext2 zip.
[T-Mobile Samsung Galaxy Note II] bhowanidin:
Sounds great! Thanks
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
Upload is done. Link is being added to OP... here it is right here tho so you don't have to wait for me to mod it.

[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Thanks Bro, what's next!!!!:D
[T-Mobile Samsung Galaxy Note II] bhowanidin:
I'm still a little confused. I know this will wipe /data, system, and cache but I see that you said it will restore then once done converting to ext2. A couple of questions, if I may:

-Does that mean I don't have to redo my whole ROM a là fresh install?

-Won't the AROMA zip restoring the backed up partitions restore them to ext4?

-What's the point of the original back up to external sd card - to "return" to ext 4 (ties with above question)?

Hope I wasn't annoying. Basically I get what to do, but would like a more in-depth explanation of how the ext2inizer (nice name) works, for my curiosity. I also feel it will help a couple n00bs (no offense) who may be intimidated. Thanks!
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
Questions are good. don't worry about that.

It is basically copying and zipping up your system and data files as a backup, the reason why this needs to be done to your external storage is because if you choose to do the /data mod as well, that entire block is getting wiped... Which means your backup would be toast.

And no, they will restore as ext2

MASSIVE performance boost.
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
lol, no.... I've been running the mod now since Wed, I think. . I'm referring more to maybe kernels and possibly AOSP/CYAN ROMS. Would expand the pool of users:thumbup:
[T-Mobile Samsung Galaxy Note II] dwitherell:
Hehe :)

EDIT:

Fwiw - md5 0D10AA6C6C408363C366350ADC7F59ED

And remember - you gotta be careful flashing things after this - edit those updater-scripts :)
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
-Does that mean I don't have to redo my whole ROM a là fresh install?

Answer : No, just "restore" the sys/data file you saved..

-Won't the AROMA zip restoring the backed up partitions restore them to ext4?

Answer: No, when you restore your Sys/data folder just make sure the rm-f option in twrp is checked. .

-What's the point of the original back up to external sd card - to "return" to ext 4 (ties with above question)?

Answered in the above answer, as long as the rm-f option is checked it will install as ext2, not 4..

Hope that clears it up for you. .:thumbup:
[T-Mobile Samsung Galaxy Note II] Kal-El7:
lol...I'm back home now, so I can properly respond (without texting while driving) hehe...

Man, you're the best! Thanks so much!! The Bullet Kernel was updated some time ago, you are correct. I followed a reviewer online (GalaxyNote2Root) when he reviewed Bullet specifically for SGH-T889, which can be downloaded straight from this link here. This is what I had been using with exFAT, overclocking to 1.9GHz and retaining T-Mobile's Wi-Fi Calling capabilities. This would be great! This would be good if we got this up.

But I'm curious about trying this Perseus, which this link here is where I can get the SGH-T889 version. OC capable to 1.8GHz and GPU OC and UV capable.

I'd like to try out this kernel, since I haven't done so before. But I know I'm a Bullet fan thus far - with 25+ hrs of battery while logging nearly 50% of that time with screen-on time plus Wi-Fi and with 30+ being my absolute best on record.....I'm a little biased in favor of Bullet thus far.

Let's see what Perseus does. lol... =)
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
What ROM are you running with the Bullet kernel?
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
everybody please read OP again, particularly the top part.... please keep in mind this modification is device specific, kernel specific, and android version specific.

Until further notice
[T-Mobile Samsung Galaxy Note II] Kal-El7:
At first I ran Bullet on this ROM here with version 14 being an insane battery-saver. They're up to version 20 now. Now, I've moved on to this amazing ROM here. This is where I'm trying out my kernels here. I've been using stock kernel since moving over to my current ROM now, however I recently threw Bullet in there and I was pleased. I haven't had the chance to do one of those all-nighters (awake for more than 24+ hours, which is what I did to test Bullet in the previous ROM) for this ROM, but little by little I'm studying its performance on my current ROM. Now I'm checkin' out Perseus before I really grind Bullet into the ground on my current ROM just yet.

---------- Post added at 08:27 PM ---------- Previous post was at 08:22 PM ----------

Hence for why you asked about my Bullet that is specific to SGH-T889.

Firmware T889UVBMD1 Android version 4.1.2 on this ROM.....because you wanted to get this to work. You're the best, man. Thanks! =)
[T-Mobile Samsung Galaxy Note II] jshealton:
What kernels can I use with this mod. I am currently running saber 32. What needs to I be modded to make that kernel work?
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
The only kernels that can be used with this are the ones provided in the op and the aroma installer.

To make them "compatible" you need to extract the RAM disk in the boot.img and edit the mount call outs to ext2
[T-Mobile Samsung Galaxy Note II] manu_up:
Hi, Will this mod be compatible with the n7105 version. I read the thread and you have mentioned device specific, so is this only specific to t-mobile variants or is it safe to try this on n7105 since all t-mobile roms n kernels are n7105 compatible as well. Thank you
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
Hasn't been tested by myself personally nor do I know for certain if it will work, but give it a shot if you'd like.
[T-Mobile Samsung Galaxy Note II] SIGMAxB:
Tried to use aroma option and got caught on a boot loop wiped dalvik and cache then backed up both system and data Completed with a zero rebooted and looped did I miss something jedix 15 by the way
[T-Mobile Samsung Galaxy Note II] dwitherell:
What are all of the options specifically you chose (there are four choices you make in total)? Did you wipe anything after flashing the aroma? Pay attention to the output screen as it's flashing (before the complete with a 0 bit) - anything pop up there as an issue perhaps?
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Could possibly be some compatability issue with Jedi and the Trinity kernel. Did you do a battery pull and try rebooting again? Sometimes it just happens. . I was running Jedix with no issues
[T-Mobile Samsung Galaxy Note II] SIGMAxB:
I did wipe cache and dakvik and fix permissions then booted will try again do I need to flash the kernel or is all included
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Should of flashed the Trinity kernel, check in about device. Should say Morfic..
[T-Mobile Samsung Galaxy Note II] SIGMAxB:
Didnt get far enough for that boot looped let me rephrase my previous question do I need to flash any of the files in the op or just use the aroma
[T-Mobile Samsung Galaxy Note II] bhowanidin:
Under settings in TWRP, did you make sure to check "format with rm -f"?
[T-Mobile Samsung Galaxy Note II] rancidm:
Yeah still not working.. wont back up and restore from within aroma app.[/B]

sticks at samsung note 2 , pull battery , going to restore sys,data manually

ok aroma couldnt back up to sd card but i already had a back up. after aroma installer. pull battery and manually restore sys and data .. works..
[T-Mobile Samsung Galaxy Note II] SIGMAxB:
That I did not is that before I start the aroma installer maybe a write up for those that haven't been following
[T-Mobile Samsung Galaxy Note II] dwitherell:
I would try it again without the wiping or permissions fix. The aroma (and formatting) does all the wiping you'll need, and yes the kernel is included. Perhaps the cache wipe set it back to ext4... not sure.
[T-Mobile Samsung Galaxy Note II] SIGMAxB:
Gonna try will update later thank you guys
[T-Mobile Samsung Galaxy Note II] rancidm:
ok aroma couldnt back up to sd card but i already had a back up. after aroma installer. pull battery and manually restore sys and data .. works..
[T-Mobile Samsung Galaxy Note II] dwitherell:
Any info on why it couldn't back up to sdcard? Did you not do the backup/restore from within aroma? It looks for specific filenames in specific directories...
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Yep, best way to go about it (from my experience this morning anyway) is letting aroma create the backup during the install process. But that might depend on where your system / data backup is located if you've already backed up prior to install. If you left it on your internal as compared to ext.. because as we've found out, the aroma installer must look strictly at the internal..
[T-Mobile Samsung Galaxy Note II] Smartassassin:
Is this working with cwm? Are any additional steps required if using cwm?
[T-Mobile Samsung Galaxy Note II] dwitherell:
In theory it should work with cwm, but tbh I haven't verified that. Report back if you give it a go though :)
[T-Mobile Samsung Galaxy Note II] rancidm:
Yes from within aroma package didnt work.Just gave an error[ cant rememeber what it was about sdcard] then finished and rebooted to Samsung logo and halted , pulled battery, back to recovery and loaded restore sys/data manually. worked
[T-Mobile Samsung Galaxy Note II] Smartassassin:
Tried flashing zip and it wouldn't even start. Tried getting a log but it was blank.
[T-Mobile Samsung Galaxy Note II] dwitherell:
The aroma checks to see if you have enough space for the backups - it might be worth lowering the bound on it as its compressed now... but without knowing the specifics I'm just guessing really.

Odd - was there any error at all reported? I thought aroma packages would at least initialize in cwm even if there was a problem with the contents...
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Odds are the error message was "unable to locate backup" reason being most have been saving the sys/data backup to the ext sd card, with good reason of course considering the internal gets wiped and the emphasis placed on where to save it. Once the Aroma process is started and it asks "would you like to make a backup" most think no, I done that already not knowing it won't look for the backup on the ext sd card..:p

So what I'm suggesting,

There should be an updated aroma installation guide, not that it's difficult, but folks should be made aware of the Sys/Data location and then placement of the dsk_check file. .
[T-Mobile Samsung Galaxy Note II] dwitherell:
Probably a good call.

I'll leave that to the OP - but here are my thoughts:

The aroma installer will make and restore it's own backups, but only those (not completely true but true enough for most). The aroma installer is basically tar-ing and then gzip-ing your /system (and /data if selected) directories (that way it keeps symlinks and permissions, but not partition format like dd seems to do) and placing the backup file(s) on your external sdcard in a directory called DISK_BACKUP (much like it was laid out in the OP). The file(s) - called system.tgz (and data.tgz) - are then looked at for restoring, etc. when done through the aroma installer. Basically the backups/restores are SPECIFIC to the aroma installer - if you don't want to use those then make sure NOT to elect to do the backup/restore bits. The init.d disk check script option at the end of the installer gets placed in /system/etc/init.d.

The original remaining-space-checks were based on a dd approach, so they are WAY conservative and should likely be adjusted - I'll make sure to let the OP know.

Hope this helps :)
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
Thanks dwith... Yeah I'll look at this later when I get home.
[T-Mobile Samsung Galaxy Note II] Smartassassin:
Yeah. I had to place the ext2zip on external to get to fire up on cwm. I stepped away from my phone after about a half hour. I came back and I was in recovery. How do I tell if it worked or not. Still showing neak kernel.
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Definitely, it's just that the two approaches aren't well defined.

The aroma installer option is easy peasy. Just flash the zip, make backup (in aroma installer) so reinstalling sys/data is a breeze. Then place dsk chk file. Bam, done..

It's just that info isn't there (aroma install guide) for those that haven't been following the topic from day one, the two processes kind of run together.

Need two well defined, separate install guides, not that it's difficult, but after reading the tons of supporting data and the initial install guide which is spot on and well written by Sir Manley, it's easy to run the two methods together because there's no break to specify best route or course of action for aroma install. .
[T-Mobile Samsung Galaxy Note II] dwitherell:
Yeah it doesn't sound like it worked - the aroma bit should wait around asking if you want to reboot or not. I'll throw CWM on my phone in a bit and test it out - what version are you using?
[T-Mobile Samsung Galaxy Note II] jpeps:
All I need is the aroma installer to make this work flushable mod to ext2 to work
[T-Mobile Samsung Galaxy Note II] Kal-El7:
I agree. I'm coming in late on this....so I'm a little dizzy as to what's the best approach as I attempt to read evey post, word for word, from everyone while ignoring all the special people in my life around me. It gets me in trouble. =)
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Thoughts?
[T-Mobile Samsung Galaxy Note II] dwitherell:
Looks good, assuming you wanted data, cache and system to be ext2. Was there something else amiss there?
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Negative,

Just wanted to throw it out there so folks know how to verify their install. Just to be clear as dw suggested earlier in the thread. To verify just use Terminal Emulator and type mount, hit enter..
[T-Mobile Samsung Galaxy Note II] rancidm:
exactly what does this do ? fsck DISK CHECK FOR INIT.D
[T-Mobile Samsung Galaxy Note II] Kal-El7:
Rookie question,

On your screenshot.....

/dev/block/mmcblkOp3 /efs ext4 is okay? The system, data and cache I see is ext2. Just starting to learn. lol...
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
Runs the files system check command for ext2 and verfies there are no disk errors/corruption and if there is, repairs it before attempting to mount.

It is important
[T-Mobile Samsung Galaxy Note II] Smartassassin:
The newest, without the on screen buttons
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
Updated OP with instructions regarding the installer and also updated the installer itself.

Post questions, comments, concerns, etc etc...
[T-Mobile Samsung Galaxy Note II] rancidm:
i never used it ...
[T-Mobile Samsung Galaxy Note II] jpeps:
If I start it will delete my sdcard or will it be ok or I still have to move my files to computer
[T-Mobile Samsung Galaxy Note II] dwitherell:
It depends on what you do really - if you only make /system ext2 then it won't wipe anything related to either sdcard. If you format /data and /cache along with it, then your internal sdcard will get wiped, but if you back up your /data partition this should include the info stored in /data/media (your internal sdcard). All that being said - its ALWAYS better to be safe than sorry so I would move files to a PC/etc. just in case.
