EXT4 Q2.5 is Fast and Furious

Subjectively, this is the fastest I've seen. I opened Autostarts which seemed to take 60 seconds plus to fully load all the applications before on any ROM/release (never actually timed it - just remember it taking f..ore..ev..er) now takes less than 20 seconds. Filesystem is smoking compared to RFS!

SWEET!!! Thanks for all your hard work D! Coming together nicely! :D :D

dameon I got stuck also at the sammy screen what worked for me was that I odin dk28 extended let it reboot afterwards, then tried the process all over again.
[Epic 4G Android Development] hayabusa1300cc:
Thanks for your input! Im waiting till my phone syncs all the 155 apps I had installed before I do any testing lol. 2 programs I will use to benchmark real world is ES FILE EXPLORER that is super awesome, but runs slow. And APP CONTROL takes a lil start up time lading 155 apps (;
[Epic 4G Android Development] Dameon87:
Flash this kernel on last step instead of the one provided: http://efragtv.com/android/EXT4-Kernel-FINAL.zip

Any chance of some 4g tethering with quantum?
[Epic 4G Android Development] TurboFool:
Getting ready to do this after some backups. VERY excited. Quick question I've never gotten around to asking: outside of personal preference in design, any advantage to using the AOSP lock screen, such as performance or memory usage?
[Epic 4G Android Development] edonnelly:
Same for me. I'm still not sure what the advantage of keeping the "old" recovery around is, but now that I can get into whichever I need, I guess all is well. I'm doing a backup with the "new" recovery now.
[Epic 4G Android Development] hayabusa1300cc:
Alright Big D! I am glad to post this...

First time opening app control, it loaded twice as fast judging by the speediness of the count. I cleared it out of memory then opened again, it was faster than it just was, the numbers went by blazing fast.

In ES file, I love it but its way damn slow. on first entry of a folder with lots of files, it still takes a bit on 'getting file list' but not as long as with RFS.

Afterwards without closing the app, going into the same folder back and forth its instant, even deleting files within the folder its snaps in and out.

On RFS, it would be 'getting file list' for a bit every transition and I used to dread it lol.

So this things in real time does prove its benefits! Cant wait to find more
[Epic 4G Android Development] Dameon87:
hayab, flash this kernel bro: http://efragtv.com/android/FinalDK28EXT4.zip

Should provide even more of a boost in performance, and it will improve Quadrant scores to around 1600 ish

EDIT: Fixed link, sorry :P Wrong item in clipboard.
[Epic 4G Android Development] hayabusa1300cc:
BIG D look at this discovery, when the last time have you seen this low of failure rate in red?? I hever have came close!
[Epic 4G Android Development] ericizzy1:
hey Dameon87, im getting connection error on the email exchange i have. any way to get the stock 2.2 email that works with your rom? thank you
[Epic 4G Android Development] hayabusa1300cc:
LOL i wonder what it was before hehe

I just seen this, i will fash this!!

the pic of the FPS test was done without this kernal

but still sick performance! you are on to something man =]
[Epic 4G Android Development] gharris040604:
Yea that kernal def boosted my scores in quadrant 1695

Great work sir
[Epic 4G Android Development] badwolf:
Is the dk28final the same or newer than. The ext4final that fixed the clockwork? And thanks for the great work
[Epic 4G Android Development] dhero1:
same here - i've never been able to use the gtab email apk with my POP acct - but does works well with my work Exchange acct
[Epic 4G Android Development] edonnelly:
I actually get the "connection error" off and on with my work exchange account when using gtab email. The weird thing is that this started after I'd been using it for a couple weeks, and during a time when I wasn't changing roms (was on an earlier Quantum). I never did figure out the problem, and it is intermittent now, occurring when I sync more than three days worth of emails. In any case, the problem for me well predates Quantum 2.5 and it has occurred in other roms when I use that gtab email, so I think it's a problem with the app itself. I'd love to know if anyone with a galaxy tablet is actually having this problem.
[Epic 4G Android Development] Skidiver:
It has been more 5 minutes and it still on the Samsung screen...should I wait longer for it to reboot?
[Epic 4G Android Development] badwolf:

[Epic 4G Android Development] Rileyy-:
This is a dumb question but how do you add the addons ?
[Epic 4G Android Development] fastmikey1969:
Flash the zip file in clockwork.
[Epic 4G Android Development] JudasD:
I started having issues too. The only way i found it to work is to set my sync amount at 3 days. anything other than that (i like to use one month) and i get connection errors. kinda weird.

I'm stuck on the "can't get passed samsung screen" issue as well and have tried EVERYTHING to get off of it... the latest i'm going to try is this DK28-EXT4Kernel-FINAL.zip (hopefully it's newer than the other ext4 file!

Looking for suggestions, anything, to get it working again! Even to flash it back to my nandroid backup (which didn't work from CWM either)...
[Epic 4G Android Development] ericizzy1:
if i got everything working, what steps do i need to do before flashing this fix? thanks
[Epic 4G Android Development] theimpaler747:
Just flash from recovery like a rom, only no wipe :)
[Epic 4G Android Development] Dameon87:
Just flash it =]
[Epic 4G Android Development] ericizzy1:
thanks, i flashed the zip u sent me, but the roms original email still there. any advice? thanks
[Epic 4G Android Development] visions138:
Is there a walk-thur or steps for people coming from CM .Thanks in advance :D

1. run clickthru.zip

2. flash the CM compatible kern ?

3. flash rom CM or another one ?

4. do you need to flash the freeze fix also?
[Epic 4G Android Development] chris378:
So i work for sprint and im trying to setup my work email but it will only setup correctly with the stock email. Im running on the 2.5 with ext4 but when i try to flash the stock email it wont install it to the rom..any suggestion ? Loving the rom and its extremely smooth and fast
[Epic 4G Android Development] Dameon87:
Let me check the normal email apk. It should be fine though.
[Epic 4G Android Development] chris378:
when i flash it it tells me e:failure at line 3
[Epic 4G Android Development] Dameon87:
Are you in the right recovery? It must say 2.5.1.2 at the top.
[Epic 4G Android Development] chris378:
how do i get into the .2? Not by holding the 3 buttons bc that brings me to the normal rooted clockwork
[Epic 4G Android Development] chris378:
Nvm found it..idid the death grip then went to advance and then rebooted into recovery thanks tho im flashing now
[Epic 4G Android Development] chris378:
Works perfect after i went to manage apps and cleared the data on the email after i flashed..gave a fc before i did that works great now
[Epic 4G Android Development] MasterQu:
MY noobness is showing. Either I am over thinking this or overlooking something. Do I have to follow all the steps in the other post about ext4 and how to set it up or just flash 2.5 like I did for 2.1 or any other rom I've put in?

If I do have to follow all the steps from the other thread is there a way by chance to simplify the process?
[Epic 4G Android Development] drizek:
No, just flash the rom. The other threads are just so that the author can give credit to the other devs.
[Epic 4G Android Development] johnyardavid:
Yes, you must follow the steps to get ext4 first. Then flash the rom.
[Epic 4G Android Development] edonnelly:
If you are running 2.1 fine then it's really not as complicated as it seems to get this to 2.5. Basically all you need to do is put the two zip files from the ext4 thread and the 2.5 rom onto your SD card. Then follow the directions on the ext4 thread (those directions include flashing the ROM, so there's nothing you need to do from this thread except get the file itself).

Though it seems complicated when you read the ext4 thread, all you are doing is opening a dos window (so you can type a reboot command to the phone a couple times), flashing the zip files with clockwork at the appropriate times, and running a bat file. It doesn't take but a few minutes more than a regular rom flash.

It sounds like a lot of the people having trouble were coming from other roms, not Quantum 2.1.
[Epic 4G Android Development] jk175d:
I liked that I could easily flash to Quantum 2.1 from 2.0 without doing a full wipe so I didn't have to take the time to redo all my home screens and widgets. Is that the case here going from 2.1 to 2.5 or does the flashing of ext4 necessitate a full wipe this time? TIA
[Epic 4G Android Development] dnathan13:
I would do a full wipe to be safe. Just make a backup first and once you have everything installed use advanced restore in clockwork to only restore data. You will get most if not all of your previous setup back.
[Epic 4G Android Development] Dameon87:
A full wipe will happen. The ext4 mod wipes all data on the phones cache data and system partitions. Use titanium backup.
[Epic 4G Android Development] jk175d:
That's what I figured. I do use TB, so restoring apps and data is a breeze. But restoring my homescreens always takes some time.
[Epic 4G Android Development] Dameon87:
Once you have ext4, you won't have to redo the ext4 fix unless you odin. So subsequent updates will not require a full wipe
[Epic 4G Android Development] codest3r:
Yeah, TB is worth every penny for transitions/migrations like this.

What do you mean by restoring your homescreens? Ever try ADW? Has nice backup/restore functionality. Also, I think D recommended ADW EX somewhere here -- ADW EX has some pretty cool effects! You may just **** a brick (not your phone).
[Epic 4G Android Development] chris378:
Will the gingerbread 1.6.5 full theme work with this ext4 ?
[Epic 4G Android Development] SwimDrewid:
Yes. Worked fine for me. Am running mysterious beast with animations (successfully) now.

Just make sure the zip downloads completely - I ended up dling on the computer and pushing to the sd card
[Epic 4G Android Development] smoothone:
Here's some advice, DO A NANDROID BACKUP BEFORE YOU MOD ANYTHING! It says that in almost every mod thread but then again I see you have difficulty following instructions. Hope that helps.
[Epic 4G Android Development] SwimDrewid:
Qft. Scrollable, hidden dockbar is so much more elegant than launcherProPlus
[Epic 4G Android Development] smoothone:
Umm no, I have done tons of modifications much more complicated and yes as simple as it really is it just wasn't that simple! Followed directions and reboot recovery just sent me to the old version of clw. Had to Odin twice.
[Epic 4G Android Development] smoothone:
Just think of ext4 as higher quality paper you are printing on versus the lower grade paper. You can do all the same mods that you did before!
[Epic 4G Android Development] MasterQu:
Yeah. Easy I think not lol. Running through the steps and I'm getting hung up on the .bat file. I'm getting fail messages after the pushing the kernal modules alerts. No idea how to fix that one. :confused:

Ok found it. the error in the .bat file on line 10 is still there which is why I could not install. That info needs to be put at the front of the thread. I could of saved an hour of frustration lol. My fault I guerss I didnt read the entire thread before starting.
[Epic 4G Android Development] MasterQu:
While I'm waiting for my apps to load another question: ap2sd, ok to use with ext4, does ext4 replace it, or do I need to delete ap2sd once it dl's from my google sync? Tyia....loving what I am seeing so far.
[Epic 4G Android Development] smoothone:
Just think of ext4 as higher quality paper you are printing on versus the lower grade paper. You can do all the same mods that you did before! EXT4 just replaces the Samsung RFS filesystem with a faster one. It doesn't take the place of anything else.
[Epic 4G Android Development] bdf:
I cant ever get The Galaxy Tab email to download my POP3 (godaddy domain), I downloaded the stock app from your Quatum store, but it immediatly FCs.

Any idea how to get either to work?

Also, when I go into adb, how do I know EXT4 is running? It just gives me a "$"

With Launcher Pro, Im just not seeing its that much faster.

Thanks
[Epic 4G Android Development] codest3r:
Did you flash it from the updated CWR (x.2) or the original?

Regarding EXT4 - if you want to see an output on the command line try this post.
[Epic 4G Android Development] bdf:
I ran it through the .2 (new version) anythign else I applied throught old got ignored.

So on the adb for EXT4, am I supposed to get a $?

Thanks
[Epic 4G Android Development] codest3r:
I haven't tried stock e-mail with your e-mail host to confirm. You could open a bug to corroborate and confirm the issue and get it in line for a fix. http://code.google.com/p/quantum-rom/issues/list

You mean for ADB Shell? I think the default prompt is a $. Type "su" to go to root #.

[Epic 4G Android Development] insanity213:
+1 on this, but in all fairness I didn't wipe so for all I know it's self inflicted. Also, I get a touchwiz FC if I remove the stock camera app and use the camera button to start the replacement app. Not sure if anything can be done about that, I'll live with the FC just to not have the stock camera app on my phone though...
[Epic 4G Android Development] jyabroff:
I am getting the samething. I wiped all the caches 3x, upgraded the modem. I find I can make calls but when I hit end I get a FC and then it appears my radio resets.
[Epic 4G Android Development] abmcbride85:
I can confirm this too. Did all the wipes 3x also... Other than that great rom. I'm sure this fc problem will have a solution with in a day or two.
[Epic 4G Android Development] bdf:
Ill look into the email.

On the EXT4, I go to my cmd prompt, type cd/

then type adb shell and I get

"$"

I type su and get "su"

am I set up on EXT4?
[Epic 4G Android Development] codest3r:
When you type "su" your phone will pop up a superuser request (not if the display is asleep - make sure you watch for it) permission to grant superuser status. You have to click OK, or your "su" request for superuser times out.

Also, you don't have to be in adb shell to run "adb shell mount" or "adb shell df" from the Windows command line. If you run "adb shell mount" you will see /system /cache and /data (stl9-11) mounted ext4.
[Epic 4G Android Development] bdf:
Ill just run K-9 for now, I like the stock email I really wish the Tab email worked. Does anyone have it working on POP3?

Thanks

Still curious if im on EXT4, I assume that just cause I have Quantum 2.5 running that means nothing.

[Epic 4G Android Development] bdf:
Yep, got it,

thanks!
[Epic 4G Android Development] paul41598:
I've read the last few pages, but can't seem to find my answer. Do I need to still install the EXT4 Mod or is it built into the new rom (v.2.5.0DK28)? Thanks
[Epic 4G Android Development] smoothone:
OMG this hurts :~(
[Epic 4G Android Development] smoothone:
This also hurts :)

Yes you have to install the EXT4 mod if you want to use an ext file system. It is not in the new rom nor does the new rom require it. Guys please just google file system and see what it is. You can use the new rom or any other new rom with or without this file system.
[Epic 4G Android Development] JudasD:
i upgraded from 2.1 to 2.5. I did this with the initial ext4 upgrade package and made the necessary changes to the setp2.bat. Worked just fine first try. Then upgraded as the new kernels came out.

So far i dont feel any improvement from the ext4 file system. Maybe it's just me? I love the quantum roms so 2.5 is what i'm gonna stick with.

Only issue i have is the Galaxy Tab email will not work with my exchange server on any sync setting other than 3 days.

Good work Dameon!!

JD
[Epic 4G Android Development] paul41598:
Thanks for your quick response. But I guess I could have phrased the question better. I wasn't asking if you needed the EXT 4 MOD to use the rom, just asking if i was already built in, or if the MOD still had to be applied after the rom was installed, which is the case I guess. Thanks again though.
[Epic 4G Android Development] TurboFool:
Not digging the Tab email on this screen size, but I can't get the stockemail.zip to install. Recovery gives me an error message, as does the installer. Is this a compatibility issue between Clockworkmod and EXT4?
[Epic 4G Android Development] TurboFool:
Since nobody else appears to be taking your question seriously, or even trying to understand it, I'll answer: From what I can tell, and the link on the OP, yes you still need to install EXT4 before you can install this ROM.

Personal TIP: track down the STOCK DK28 ROM and flash it with ODIN first, and then use the Oneclickroot method to install Clockworkmod, then follow instructions from there. I had endlessly bad luck following the instructions coming from a different version of DK28. Don't use extended or anything else unusual, just find the stock version (go to the FAQ thread and follow it to the wiki which should have a link) and go from there.
[Epic 4G Android Development] ZenInsight:
If you didn't install in this order:

From dk28 (preferably stand stock...not extended).

1. flash clockword recovery with redirector

2. Copy the two zip files from the OneClickEXT4 directory in the first step, and place them on your SDCard (You can use adb push, usb mass storage, or an sdcard reader)

3. using ADB reboot into recovery

4. Flash prepare.zip

5. reboot into recovery again from CWM "advanced" --- "reboot recovery"

6. using adb make sure with the command "adb devices" you see your device show up. If it doesn't disconnect the usb cable and reconnect.

7. now just double click the install-ext4.bat file - It will go through a long process of installing ext4.

8. Reboot into recovery again using "advance" options in CWM (ClockworkMod)

9. Wipe data/cache/dalvik x3

10. Apply ext4 compatible ROM (Quantum 2.5 in this case)

11. Apply kern-dk28ext4.zip

12. reboot to system

....then you are NOT on ext4. Just installing the 2.5 ROM doesn't install a brand new file system.
[Epic 4G Android Development] KUHawk:
+1. Follow the above tip and then follow the Ext4 link from the OP. I am extremely raw with all of this, but by taking my time and following the directions I was able to go from Stock to Quantum 2.1 back to Stock and onto Quantum 2.5 with Ext4 support with absolutely no problems and it took less than 10 minutes. TAKE YOUR TIME. READ AND FOLLOW THE DIRECTIONS CAREFULLY.

Thanks to everyone who contributes not only to the ROM development and testing but to the forums for support as well. No it isn't rocket science, but remember that everyone was a noob at one time. It takes the same amount of time to type a helpful hint as it does a sarcastic comment.
[Epic 4G Android Development] ZenInsight:
Sounds like you did what I posted above you then. Correct?
[Epic 4G Android Development] MILcityBoi:
Man, this thing fast...I am diggin' it a lot and added the Gingerbread theme and lovin' it, thanks a million.
[Epic 4G Android Development] ragnarokx:
+2 for using Odin to go to straight DK28 and then one click root/Clockwork. This installation couldn't have been easier. Thanks Dameon87!
[Epic 4G Android Development] TurboFool:
Hmmm, Email force closes after installing stockemail.zip now. Any thoughts?

EDIT: Never mind, had to use Titanium to wipe its data.
[Epic 4G Android Development] smoothone:
Someone correct me if I'm wrong but no you do not need to install the ext mod in order to flash Dameons 2.5. Why would you? Ext4 is just a file system and you don't need it to run the new rom or any rom! File systems are completely separate from os!
