Yes it is perfectly okay for it to be checked. But it doesn't have to be you can uncheck it if it makes you feel better
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
One other thing when I typed in “mk2fs /dev/block/mmcblk0p16” nothing really happened, said it didn't exist or something along those lines I forget. There shouldn't be an "e" in there "mke2fs" or something... I'll try it again and see what happens. But after flashing the the data cache zip I'm stuck in a bootloop on the Tmob 4g LTE screen... lol:silly:
[T-Mobile Samsung Galaxy Note II] Skater4599:
Awesome, the app worked and I confirmed all /system /data and /cache partitions are all ext2. I will monitor and test some and see how much difference it makes with speed and battery but I can say for sure it booted up super quick. Thanks again! :good:
[T-Mobile Samsung Galaxy Note II] benji667:
does the size of the card matter?
[T-Mobile Samsung Galaxy Note II] psycho4us4:
I don't know if you know it or not but this mod is confirmed working on I317 as long as you have a external SD card that is smaller than 64 gigabyte two people can confirm this if you go to my how to multi window floating apps page in my signature and read through towards the end you will see what I'm talking about
[T-Mobile Samsung Galaxy Note II] benji667:
bro u confuse me now .. i thought u said 64 is fine earlier... i mean i needed to use smaller to make the mod but will my 64 b ok to use after?
[T-Mobile Samsung Galaxy Note II] psycho4us4:
I know nothing about a 64g chip cause I don't have one. [MENTION=842695]billb23ok[/MENTION] has one. He knows more about it. You said it worked mostly. After you put a smaller card in. Bill said the same except he got his working 100%. Until someone says something different it is suggested to use an external SD smaller than 64g
[T-Mobile Samsung Galaxy Note II] benji667:
ah ok
[T-Mobile Samsung Galaxy Note II] benji667:
I really feel the performance boost but I'm not seeing the battery life extension ppl talked about.. not complaining cause its still sweet just saying tho
[T-Mobile Samsung Galaxy Note II] M.Q.:
Hi. I'm the author of the DiskInfo app and I just found this thread and your screenshot.

Can you please post an output of "cat /proc/partitions" and "cat /proc/devices" commands ?

I am asking because the "Partition type: unknown" and "partition number: 0" on the screenshot seems to be wrong. I am not sure if it is something with this mod or is it a defect in my app - I will try to look into it.

Thanks!
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Need some advice, tried pulling the battery to get back into recovery (TWRP) but as soon as I stick my battery back in it auto starts so I can't ... Any ideas?:confused: Sheeet...
[T-Mobile Samsung Galaxy Note II] theboss23:
Take the battery out, and leave it out for about 5-10 seconds than put it back in. Should stop the phone from trying to auto-boot.
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
That is certainly odd...

Pull battery.... Don't put it in immediately... Instead hold the power button for a few seconds, then put it back in... Manually boot to recovery, once you get there, format /system again, make sure rm -f format option is selected... Then wipe data under WIPE and then ADVANCED WIPE... wipe cache as well. Then flash the kernel zip for just system. Reboot. Let me know.

Again, like I said.... The fsck script is important. And I really hope you didn't mistype something and hit some other partition... That would mean an odin restore... This is also why I suggested moving your system and data backups to a computer as well.

Again, let me know how it goes, I'll be checking on the thread.
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Yeah, having issues running the “mk2fs /dev/block/mmcblk0p16” command, say's it's not found? Been there yet?
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
Also, [MENTION=2236421]steve.[/MENTION]... Take a look at the image I am showing you....

mke2fs is a format command for ext2 (as seen in xbin here)

Probably typed something wrong.

Ext stands for extension, ext 3 and 4 are all extensions of each other or "revisions" the mke2fs command also is used to make ext4 by adding ".ext4" on the end.

Make surree you are taking your time bro. If the directions are being followed you should have absolutely no issues. I was very careful to make sure I gave you guys the safest route to do this manually. I'm working with dwitherell right now to get this all aromafied but for now it needs to be done exactly the way I instructed.

Again, I'll keep checking back here. And if you need to shoot me a pm feel free and I'll hit you on hangouts
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
So do you want me to start back at square one? What about the “mk2fs /dev/block/mmcblk0p16” issue, say's it not found...

But for now, you want me to just reboot, wipe, flash kernel and see what happens? Or should I go through all steps again from the beginning?

---------- Post added at 11:09 PM ---------- Previous post was at 11:06 PM ----------

Got back into recovery, double checked everything, it's the second command “mk2fs /dev/block/mmcblk0p16” that's giving me issues, say's it's not found, so I'm assuming that's a provlem eh?:confused:

---------- Post added at 11:12 PM ---------- Previous post was at 11:09 PM ----------

Just to be clear, it's not suppose to have the "E" correct, “mk2fs /dev/block/mmcblk0p16” as compared to “mke2fs /dev/block/mmcblk0p16”
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
mke2fs.... With an e.... My bad bro

I'll fix that right away its mke

EDIT*** k fixed my little booboo... You can see how one little mistake can take a ***t on your day? Lol

In any case, any time you get a return error like that for a command, it means one of two things typically - you either typed the wrong command or the path was not a valid path.

So when it said "mk2fs not found" it was basically telling you "hey that's not a command dummy. Go back and slap admiral in his e-face and don't proceed to next steps."

;)
[T-Mobile Samsung Galaxy Note II] wbonney4:
I couldn't get HDparm to show up in terminal. I take it it didnt work?
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
lol, no worries.. kinda thought that might be it.... but didn't want to try it without verification....:laugh:
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
Yeah sorry. Lmao.

And the hdparm won't work either. Try this.... As root user...

file -sL /PATH/OF/DIRECTORY

so something like...

file -sL /dev/block/mmcblk0p13

Will give you an output telling you your file system type. If you don't do it as root user it won't give as much information

EDIT...NM... I guess android doesn't carry the /ect/fstab file natively. Lol wow.

Just check it with a file explorer. Bastardized version of Linux here.... Thank yooouuu google
[T-Mobile Samsung Galaxy Note II] Skater4599:
For what it's worth, I ran into many of the same things, both with random times it would say directory not found, also when I flashed the kernel's he posted once most of the flash completed but upon looking closer the log said the last section failed flashing due to same error, directory not found. I went to try to recreate it again via terminal and it failed, I rebooted recovery and reflashed and got no errors. It worked after this. I had to reboot recovery many times for everything to go successfully. I chalked it up to bugs in TWRP 2.6.0.0 but I honestly didn't know (This is my first time flashing/using TWRP, i've always been a CWM guy lol)

Maybe it can help others running into these things I did when I flashed this mod tonight. I thought it was only me getting these errors.
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
Might have been the recovery fault...

But I am willing to bet the error you got was after you did the data mod... And the error was saying /data/media not found because you didn't create it after you formatted data partition.

;)

The ROM will automatically build /data/media upon boot if it doesn't exist, which is why when you rebooted it worked without errors.

Again you guys... Highly recommend twrp 2.5.3.0 for this
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Well all is good, up and running. Last issue being installing the SYS/DATA backup I made... When I boot into recovery it doesn't show the folder I dropped into the TWRP folder on the internal SD card. I can however access the original on the external, is it okay to use that one instead, or does it have to be on the internal SD? Lot's of little stuff, but want to be sure..
[T-Mobile Samsung Galaxy Note II] Skater4599:
I think it was more of a recovery fault. I for sure tried creating the directory via terminal but it kept giving me an error something along the lines of directory already existed or could not be accessed ot something along those lines, I never rebooted back into my rom, only rebooted recovery then went back to terminal and typed exact same thing mkdir /data/media and then it suddenly worked lol. I will be flashing TWRP 2.5.3.0. Hopefully it resolves some of these issues (But for what it's worth, I did get this working 100% with 2.6.0 after some fiddling)

Would have just done it in 2.5.3.0 if I had known that when I did this earlier :D

Oh well, its always fun tinkering with new shiz and trying out new apps in the process. :cool: So far I'm really happy with the changes to my phone! It in general seems better so far, and has fixed some small issues I was having before.
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
You can use the one on external
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
And of course one last issue... lol, when I try to drop the dsk_chk file in the init.d folder it won't let me, say's it's a read only file system... ?

---------- Post added at 12:35 AM ---------- Previous post was at 12:25 AM ----------

All done !!!! boot time is crazy fast... Minus the "E" issue pretty straight forward and a great learning experience..... As for the dsk_chk issue, I understand the purpose as you were discussing earlier in the thread. What is the WORST possible boot issue I could run into if I decide not to use it? Obviously as you've stated previously, if I don't use it the boot times will be really quick, and boy are they quick ...:good:
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
Worst case scenario while NOT using it and getting a disk error.......

Well, let me put it this way. Regardless of what you do... You need to keep a backup, and keep it on your external storage to keep it safe. But if you have an issue it will require more terminal work in recovery to repair the disk/corrupted.

The "fsck script" file is composed of exactly that - scripts for the fsck linux command. Fsck stands for "file system check" and physically runs through your ext2 data blocks to check them for errors. If something was corrupted during an unclean shutdown, or some other issue, it is like your /data partition would not mount... Send you in a boot loop. Only way to fix is fsck the disk and use the necessary commands to repair it (all of those are included in that script.... It will run the script before mounting /data)

I would recommend you use it. The boot up time isn't a huge deal to be a honest, and its a good preventative method for headaches.

To get the file into init.d you need to change the permissions of /system/ ......

Just download fx file... Change read only permissions by accessing /system as root .... click the yellow and green lock icon on the top right corner after you go into the /system directory. It will turn red and have an "unlocked" look when the directory is mounted as read/write. Once it is mounted as read/write, you can then drop the file in there simply by copy/paste method.

After you drop the file in there, long press on the file, rename it to get rid of the ".txt" extension. Then long press on the file again, and select permissions. Make sure ALL of the boxes are checked. (9 of them)...

You will need to download the root add on for the app. Same developer makes it.

Good luck.
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
How about this for battery life....

Winning.
[T-Mobile Samsung Galaxy Note II] rancidm:
Ok this is strange after doing everything then flashing the sys file and reboot it boots back to recovery instead of rom, so i continue following instruction finnaly cash and syss file , same result.back to twrp..couldnt restor either didnt see my sd card, oh wait i think was my mistake..

installed a new rom ...now restore ? did i lose ext 2 ? ok restoring back. .have twrp 2.5.0.3
[T-Mobile Samsung Galaxy Note II] kintwofan:
It's early and I haven't had my coffee so I may be missing what you're trying to do, but I think you're trying to tell then how verify it worked. If so all you need to do is type "Mount" in terminal emulator. It will list what file system all the partitions are running
[T-Mobile Samsung Galaxy Note II] rancidm:
I got it working now with 2.6 twrp , now all i need to do is restore data and sys, what if my back up had a custom kernal will it break ext 2 ?

im gonna load and see what happens.. cause my kernal had undervolted settings..
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
You should be just restoring the sys/data you backed up at the beginning, not flashing an entire ROM..So don't worry about the kernel. .
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Awsome, all done.

Don't notice any real difference in the boot time taking noticeably longer as of yet...could be because I keep things lite on my phone as is..

Do you recommend any benchmarking apps to reference performance? It's a little more acceptable rather that saying "seems faster"..when discussing the ext2 vs ext4 mod...
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
For those of you getting stuck after restoring your backups......

Again, you need to make sure you are double checking that setting in twrp. When you restore backups, twrp does a format of the partition you are restoring. If that setting is not checked, it will format back to ext4.
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
Guys!

Updated OP with this link...

http://mindplusplus.wordpress.com/2012/01/11/finding-the-fastest-filesystem-2012-edition/

VERY interesting indeed. An in depth test of different file systems throughput and overall performance on a machine running Linux. Tested with different IO schedulers, etc etc etc....

As I mentioned in the OP... highly recommend you run NOOP as your default for an EXT2 database. If you are on a kernel that supports Interactive governors.... you are even better off!
[T-Mobile Samsung Galaxy Note II] rancidm:
ok Im all hooked up now. Only notice mostly faster boot up...

I did however when wiping cache and dalvik i hit system and cache and did a wipe and the -f rm [whatever its called was not checked] but i then flashed system and data that was saved and its reporting ext 2 still for system. Its booting much faster so i guess i didn't lose ext 2..

---------- Post added at 03:53 AM ---------- Previous post was at 03:50 AM ----------

can we modifies the boot logos[remove t-mo crap]] and back up the whole dam thing to restore later down the road and it keep ext 2 ?

also when i type mount in termianl emulator i get /data type ext 2, sdcard ext2, cache type ext 2, external sdcard shows eror thing , but should i see a system ext 2 ?[
[T-Mobile Samsung Galaxy Note II] Steve Lazarus:
Had 6 and a half hours of screen "on time" before I plugged it in last night, pretty kick ass....

As for the boot animation, I know there's a thread out there to fix that issue, or you could use a launcher like Nova or Apex, I know one of those two have a boot animation mod.

If you back it up now and flash later I'm assuming you'll keep the ext2, just have to ensure the rm_f is checked in TWRP when you flash?... Maybe Sir Manley will chime in more on that...
[T-Mobile Samsung Galaxy Note II] Skater4599:
The boot animation can be found in /system/media/bootanimation.zip. Replacing this zip file with another one is all you will need to do. (I did this on Jedi rom, and put it back to stock) I took the stock one from a stock rom download here. You will need root permissions file manager.

As for this mod, If I'm not mistaken, checking the box for format using rm -f changes format commands into simply remove everything not format the drive. rm=remove a directory, the -f switch is to "force delete without prompt". In this way as long as that's checked you could theoretically flash whatever rom you wanted and keep ext2. Also your external sd card is not ext2, none of what the OP posted formats your external sd card. I believe mine showed as vfat and it was formatted with the SD card formatter.

I'm noticing a nice increase in battery on this mod. Yesterday I went out of town in a pretty rural area, where my phone was searching for signal for over 4.5 hours. When I got home it had been off the charger for over 12 hours and I still had 70% battery remaining, that's a nice increase from before. My friends Motorola Droid X battery was completely dead and it shut down. :p

I also notice when calculating file system usage it does this over twice as fast as it did before.
[T-Mobile Samsung Galaxy Note II] rancidm:
yeah i have jedi master rom 14 and i dont think that the boot anumation is in this directory i loaded a few from rom tool box and verified its in this directory but not working../system/media/bootanimation.zip
[T-Mobile Samsung Galaxy Note II] Skater4599:
You are right, the kernel provided in this rom must use the qmg format still or something. I notice in that directory my bootanimation.zip is no longer being used. There is also some files bootsamsung.qmg and bootsamsungloop.qmg. Not sure if these were there before or not though. I'm sure Admiral Sir Manley could shed some light on to where it's moved to, or where the kernel looks for the boot animation default. Personally I'm good with the stock one it created :)
[T-Mobile Samsung Galaxy Note II] rancidm:
Ok i installed boot animation from rom tool box and didnt work but i found this and installed and what was installed worked after ..

, so put animation in that system/media directory and then install this file..Bootanimation4U.zip, there is also

[T-Mobile Samsung Galaxy Note II] Skater4599:
Thanks Admiral, I applied those settings, I already had Trickster MOD app installed. I noticed the voltages are all increased for each step from default, will this have a downside on battery or does the OC to 2GHZ offset this?

P.S. I'm curious of the logic/reasoning for these changes and how it effects things. It's the I.T. guy in me ;)
[T-Mobile Samsung Galaxy Note II] theboss23:
So after days of trying to get this to work, I finally figured it out! It turns out that something was wrong with my current setup, after flashing jedi rom and starting from scratch everything worked perfectly! Thanks for sharing this! :good:
[T-Mobile Samsung Galaxy Note II] dwitherell:
I would be curious to learn why this is, as the OP stated he did this on Tweaked. I'm not saying there isn't an issue there, but perhaps it's specific to an option in Tweaked (just because it isn't uniformily rejected on Tweaked) as opposed to the entirety of the rom being to blame.
[T-Mobile Samsung Galaxy Note II] theboss23:
I figured I installed the rom incorrectly altogether, but it could be that I selected an option that caused the issue. I didn't mean to blame the rom at all, I just meant that there was something wrong with my setup that was causing issues. I really liked Tweaked Rom though, the customization was amazing! :)
[T-Mobile Samsung Galaxy Note II] dwitherell:
I know you weren't blaming :) I'm just wondering what could be interfering is all, no worries.
[T-Mobile Samsung Galaxy Note II] Admiral Sir Manley Power:
The reason for upping the voltage is simply to make it 100% stable for everyone. While some may be able to get away with an extremely aggressive UV table, the fact remains that it is impossible to make two CPUs 100% alike in the factory, thus making them have their own unique limits, much like an engine in your car.

This table is designed to be 100% stable for EVERYONE… not just most.

The technical reason for this is not complicated to explain but I want you to understand the concept not the theory, so I'll use an analogy as you can, in a way, compare it to an engine as well. Stay with me on this… just trying to make it sound as simple as possible…

Think of your gasoline as voltage… if you run your engine with not enough fuel, it will die out, because the combustion eventually is not forceful enough to push the pistons, rods, and crankshaft. Think of the rods and crank shaft as data being transferred across your circuitry and board….

Not enough juice, means they are not able to be moved physically.

Having just the right amount of fuel, however, or maybe even just a tad bit more than needed, will guarantee smooth operation in your engine, and it will not die on you. Crank will move, car will move (and will be even more likely to operate normally when under heavy load, which is also so so very relevant to what we are talking about here)….

Your battery will not be impacted a whole lot with these settings. You might see MAYBE 0.5% more drain out of a hundred on a typical day of usage for you. Unless you are a hard gamer… in which case you might see a couple more % (2 or 3) over the course of a full charge.

To the other user, tweaked ROM is not the issue. That’s all I can say. There is no modification in the instruction that would affect the way the ROM operates. The fact that it worked with Jedi is irrelevant to what the root cause of your issue was when you tried with tweaked. They are the same base, same version of Android. I would blame the issue on one of two things – you had a bad download of tweaked, or you didn’t follow instructions accurately as is kind of evident in your post inquiring about the init.d fsck script, as I have explained numerous times now that yes it is very important, and have explained numerous times what it actually does. Several people have done this mod (that I know personally, helped them with it personally, phone in hand) and it worked flawlessly. All of these were tweaked ROM. So if somebody is having an issue with tweaked ROM, or any touchWiz ROM, the issue is definitely on your end (bad download, not applying the CPU and voltage adjustments I recommended, or you missed something or did something wrong in the instruction).

NOT AT ALL am I trying to flame or put down… so don’t take it that way, please. Just saying please carefully examine what you are doing and consider the fact that this has worked on the 8 or so devices I have personally done this on, with no issues whatsoever.
