Thanks VeEuzUKY for this thread and the good intro! Here are my 2 cents:

This advise seems to be quite radical. Many users might happily trade in some performance loss for that extra widget and blink luxury.

And what about widgets such as agenda or todo list (astrid) that only refresh (in priciple) on a new input? They should be fine without CPU usage at all. Isn't it?

Also I am using WhatsApp and IMO for instant messanging and SipDroid for VoIP which of course consume some power even in standby. I think we should try to list those suspects and their resource consumption and then everybody can make up his decision.

yeah, I recommend that too. I believe there is some gain in performance (or less lag), measurable by quadrant benchmark. But for me it is hardly recognizable in day to day usage. Still I can see sporadic slowdowns, e.g., when typing in browser. I agree with you that probably unnecessary background services might be accountable.

I think it is not only the periodic refreshing but the permanent monitoring of tasks that eats up just too much CPU resources to be worth it.

I did not get the catch what this is good for. Isn't that the standard configuration? If so, SetCPU isn't free, so what about free tools such as CPU Tuner?

how did you figure this out? Just from draging over workspaces and lauching apps the Samsung laucher seems to perform well. It has also some nice features, other launchers don't have, e.g., direct navigation to a workspace by clicking the appropriate dot.

Performance wise Zeam should be the fastest and sleekest launcher and seems to offer all I need. For example easy drag and drop to the bottom bar. I use that as my default for now to check. Did you test Zeam against Launcher Pro?

yes, it does not have those fancy effects as the Galery but seems to be faster, thx for that hint!

seemingly these tools do not report the same. I see security storage ("Kalender Speicher") in Usage Timelyness too, but not so in Task Manager or OS Monitor.

Also there are a lot of tasks consuming CPU from time to time that I installed, but never use, e.g., SimpleCalendarWidget or WiFi manager. Weired.

I do not like tweaking around without understanding what causes this weired behavior. Probably the monitoring tools are just totally buggy?

Best,

Peter

Alright going to give this another shot when I get home.
[Galaxy Tab General] pibach:
I think both you are right.

To clean up unwanted tasks there should be ways to disable/uninstall/configure - instead of task killing it.

Hi all,

I flashed to Roto ROM and convert to EXT4 already. If I want to flash to a new ROM (Modaco for example), do I need to convert again to EXT4?

Many thanks

I have a post in Z4Root thread about the Z4Root not being able to Root my stock Sprint GTab.

firmware 2.2

Kernel 2.6.32.9

When I run the app (yes I am in debug mode, does not matter if I select temp root or permanent) the app runs through it's paces:

Running Exploit

Aquiring root Shell

(unit Vibrates once)

(unit Vibrates 2x)

Returns to the Applications screen

Does not reboot

If I select the app again it reports back ""unexpected stop" with force close button.

Did I miss something in the instructions? read them over and followed what I thought was to the letter. Any help would be appreciated.

Rooting issues

As i have found that the Z4Root oneclick rooting process is not functioning on my galaxy tablet for some unknown reason I am looking for som clear direction on how to root my tablet. Is there one post that has the complete (hoping) instructions for rooting this Toy? I saw a post in the Z4Root thread where someone has bricked their tablet (galaxy tablet I believe) trying to run the Z4Root process one time to many. I am looking to be able to root and improve my tab but gotta get it rooted first. Any help out there???

Update: I found the thread that gives the instructions one the superone click method and was able to fianlly root. I have the superuser app now... Looking forward to moving this forward.
[Galaxy Tab General] Sarsippius:
Brigop I am not sure but you may have a protected bootloader, have a look at the sticky thread in the development forum.
[Galaxy Tab General] DudeInMyrtleBeach:
Thanks for this! My quadrant score went to 1980 after this. More importantly, the tablet seemed to spring to life! Everything is much snappier now... Browsers included (stock, Dolphin HD and Mini). In fact, this little tablet is now much smoother than my viewsonic gtablet was.

I may get around to uninstalling some stock apps just for cleanup purposes, but having spent a considerable amount of time studying and understanding how android handles applications and manages memory, I won't be using any task killers or freezers or thawers as they have the potential to cause more problems than they solve, and in the end, it's just not worth the hassle to me.

Thanks again!

I flashed the overcome 1.2.3 kernel over Roto JMI + Ext4 and overclocked (and undervolted) it with Voltage Control App to 1.4 GHz. Increadible difference! The lags are gone, smooth scrolling and panning in the twlauncher and internet browser

Quadrant score at 1.4 GHz = 2139

Quadrant score at 1.o GHz = 1804
[Galaxy Tab General] VeEuzUKY:
Hi, this is great news and feedback, thanks for sharing!!

Would you mind explaining step-by-step how the update of the kenel is done? Did you use Heimdall or Odin3 and which settings you used? Thanks again:)
[Galaxy Tab General] ramski:
can you share your current voltage control setup and OC profile.

thanks
[Galaxy Tab General] pibach:
Very simple step: I used Odin, just put the overcome kernel jar into PDA, nothing else, and flash. Everything else remained the same, all apps and configuration is kept untouched this way.
[Galaxy Tab General] pibach:
Regarding voltage levels I put all to min voltage, i.e., 200mV less than regular, seems to run stable on my Tab, surprisingly...
[Galaxy Tab General] pibach:
After extensively testing Twlauncher, Zeam and Launcher Pro I can savely say that Launcher Pro is fastest, mainly because it has a keep in memory option. The other launchers begin severe stuttering as soon as they are reloaded into memory which seems to ocure every now and then, e.g., after sleep/resume. Only I couldn't figure out how to get notification overlay for Samsungs email app. Anyone?

But biggest improvement I got from Task Switcher app which alows for much faster launching and switching. Best task switching tool (tested them all, this is the only one truely fast).

I have also tested all browsers. Miren is overall most responsive and the fastest in all test regarding page load, scrolling, panning, zooming, text refit etc. I particularly like the "open in backround on click" option. Comparably are Dolphin Mini or xscope, these two are only slightly behind in speed. Dolphin HD is a good bit slower. The stock browser works also quite nicely in JMI ROM but lacks the options to change user agent. Unfortunately all browsers have problems with some pages and show content artefacts, spontaneous scrolling, badly placed input windows, or other issues.

Additionally Flow facbook app is much faster that the stock facebook app, seemingly because of better caching and incremental updates.
[Galaxy Tab General] pibach:
No. Just download ROM (I am using Roto JMI) + Kernel, flash, done. Overclock/Undervolt. Install TaskSwitcher and LauncherPro. That's it. Takes 10 minutes. 100% stable. WAY faster and better battery life. Totally worth it. All the rest posted here is just nice to have.

Here are some benchmark results (Roto JMI, Ext4@1.4Ghz):

Sunspider 0.9.1.: 4.581ms (Miren Browser)

Browsermark: 41633 (Dolphin Mini) - for comparison iPad/Safari: 35663

[Galaxy Tab General] LordSupremo:
i just bought a galaxy tab from t-mobile. so im guessing its locked on their network. its running on stock and i find it sluggish when browsing and watching movies with the browser. i removed anything that is moving on screen so it doesnt eat any resource hopefully making it a bit faster. but i guess disabling with what the normal settings have cant make the gtab faster. i have no idea how to flash, install ext4 etc im just reading what you guys posted but im scared i might brick my tab. few questions though, how can i install ext4 without flashing my rom. can i use the stock rom? anyone who have the time to help me would be greatly appreciated. thanks in advance.
[Galaxy Tab General] louser:
Hi all,

Got my tab for Christmas and finally understanding Android a bit. I too want to flash to a better ROM but have a few concerns. I am currently deployed to Iraq, if I flash to another ROM do I have to re-activate my tab through TMO? Thats a deal breaker for me as I have 4 more months here and really want to use my tab. Will I still have all the features i have on the stock ROM? I read something earlier about things not working like 3G and such. I appreciate all your help.

Lou
[Galaxy Tab General] pibach:
A) the tab is not locked and you can use any SIM card

B) browser and flash lag is fixed in JMI Roms, ext4 is irrelevant for that

C) for ext4 you need new Rom, but speed improvement from that is only marginal

D) there is no way other than to flash, fortunately it is so easy that you don't need any hint just usually, start odin, grab any JMI ROM, place file name in PDA input box, connect, and press start, takes 3 minutes and you are done. All those howtos are just far to complicated and do not help imho
[Galaxy Tab General] VeEuzUKY:
Im very confused about some of this. if I already installed the new Roto JMI Pre-Rooted v2 ROM and did the EXT4 conversion after that, to install the 1.4Ghz Kernel, do I need to go thru the process first of installing an overcome kernel or I ssould revert my Tab totally back to a Samsung Stock ROM or that does not matter?

It seems that once I install the overcome kernel it will convert the file system to EXT4, but I already did that so I am confused as to what the overcome kernel will do or why I need it...

And there are 2 sources to the 1.4Ghz Kernel:

Here:

http://xdaforums.com/showthread.php?t=932082

and here:

http://xdaforums.com/showthread.php?t=924654

Which one should I use and could you please specify, step by step, what needs to be flashed and in which sequence so that I understand what are the steps required? And there are versions of the Overcome Kernel v1.0 and also 2.1.0, so which one to use and is the install process the same? I am soooooooooooooooo confused...

Also, could you posta link (appbrain or another one) for the Task Switcher app you mentioned? I dont know this app but would like to try it:)

Thanks again:)
[Galaxy Tab General] VeEuzUKY:
Can someone help me? I had a bad feeling about doing this before I started... So I tried following exact instructions here using ODIN to install the Overcome Kernel v2.1.0 to then update the system to Overcome ROM v1.4.0.

The process of updating Overcome Kernel v2.1.0 started but after 1/2 hour of nothing happening it was still at 0% so eventually I just closed Odin and turned off the Tab.

Now upon restarting the Tab all I get is a screen with the image of a cell phone and exclamation mark and a computer.. and thats it! System does not boot or do anything else but display that screen. Does not matter if I start the Tab with just the power buttin or also pressing the up or down volume button or even if I just connect it to the charger... thats all I get.

How can get out of this? Thanks for the advice.
[Galaxy Tab General] VeEuzUKY:
Where you have the settings for these? I can find them on my system, thanks!
[Galaxy Tab General] VeEuzUKY:
Could you please give me a link for the Task Switcher App you mention? Is it the app developed by Erik Fikkert? This is the only one I found matching that name but not sure if its the one you're using:

www.androidapps.com/t/task-switcher

If this is not the correct one, can you tell me where I can find it and download it?

Thanks much!

Great info. Going to try some of these. I put the Euro ROM on my wife's tab and she enjoyed using her tab as a phone but her data was waaayyyy to slow. Switched out the modem files and she no longer has the phone capability but now she gets 4G so she's happy, however just this past week battery issues. Gonna try some of ur suggestions.

Black screen after first reboot in recovery mode

Hi there,

I'm a newbie to all of this, I tried to follow the tutorial but after the first reboot in recovery mod did'nt happen anything and I'm stucked with a black screen.

I tried a few other times starting fresh but it still turn black on reboot.

Right now my Galaxy Tab P1000 it's almost gone, the screen light up with the samsung logo when I turn it on, but nothing else comes out.

[Galaxy Tab General] pibach:
no, it is this one:

very simple. Fastest I could find. Still some lag. Better disable recent apps and only choose running apps and without blurr background.

Great idea for a thread - thanks for the inspiration!

Yesterday morning I was running right around 900 on Quadrant, now I'm consistently running over 2000. :D

My recipe, in sequential order:

Install Rotohammer's firmware. JMI Full V2 - http://xdaforums.com/showthread.php?t=939360

Convert to EXT4 - http://xdaforums.com/showthread.php?p=11510270

Apply Overclocking/Undervolting with Overcome_Kernel_v2.1.3_ODIN.tar - http://xdaforums.com/showthread.php?t=932082

Add SetCPU and Voltage Control apps from The Market. Overclocking to 1400 Mhz and undervolting (-200) to 1250 mV

I'm still running most of the "bloatware" and I like having my son's picture on my home screen in a virtual frame, so Gallery remains for now. :)

I already used Titanium Backup to freeze all the apps that are redundant and/or that I don't use, if for no reason other than to keep things simple. As VeEuzUKY pointed out, things like Live Wallpaper and other active home page items may be pretty, but they will slow you down. Of course, now I can slow down quite a bit before I'm back to where I was a couple of days ago...
[Galaxy Tab General] Distemper2:
hi guys

im new to this forum and i got my tab a cupple of days ago. it was wokring quite slowly and i decided to tweak it a little. i read some of the tweaking topics and decided ill try it for the first time. everything was fine until i got to the point where i was suppose to convert file system to EXT4. i followed the instructions correctly but it keeps failing to convert it. and everytime it fails it completely chrashes, so i must instal the firmware all over again... im running JMI Full V2 and it works fine (as all other tweaks do) but id like to try this EXT4 thing...

any suggestions?

thanks in advance!

I changed to overcome ROM, now it is at version 1.6.4. It has some advantages over the Roto ROM and I am happy with it, so just follow the steps mentioned there to do a full install. It is very easy and comes with comprehensive instruction manual.
[Galaxy Tab General] jamesbryant:
I hope this wasn't covered anywhere. I couldn't find it after a lengthy search.

I have a problem when I use Launcher Pro. When it is active, I can't connect as a USB drive. Not a real issue, but frustrating until you run across the solution.

DannyDoan's Trigger v2.6 Semi v1.2

Screen 1 (Default) & Screen 2:

App Drawer:

(Organized with LauncherPro's Hidden Apps.)

Instructions

1. Extract "Semi v1.2" into your internal SD.

2. Back up LauncherPro settings.

3. Uninstall LauncherPro and reboot into Clockwork Mod Recovery.**

4. Flash ClockRemover and LauncherProBlueCalender.

5. Reboot Phone.

6. Restore LauncherPro settings.

7. Install Clock.apk.

8. Set up icons, widgets, and background with your new LauncherPro.

**When you uninstall LauncherPro, you will have no launcher until you flash LauncherProBlueCalender, so make sure you can get into CMR without a launcher. If you can't do it, install a temporary launcher for safety, then uninstall it when you don't need the temporary launcher.

Optional (Accurate Battery & Weather Widget)

1. Go to the Market and download Metamorph. Open the application and click "Start Checks". Then click "Unzip/Extract new theme". Go through your internal SD and look for the "Semi v1.2" folder, and click Trigger_MinimalMatte_Battery. Enjoy!

2. Go to the Market and buy Beautiful Widgets for the weather widget. Once installed, go to your widgets and it'll be under "Beautiful Weather 1x1". The skin's name is "weezle_weather_icons". Change the text color to match the blue theme. I had the red hue at 0%, green around 75% (play with the green if you are picky on the shade of blue), and blue at 100%. Have "Hide Background" checked. Save & apply. Done!

Ask birgertime if he can make it into one zip file. I feel much more comfortable downloading one zip than doing all of those steps.
[Vibrant Themes and Apps] DannyDoan:
If you already did the previous all-in-one flashable zip, all you really have to do (if you just want those icons) is download the new version, extract the new icons and replace them with the old ones on your internal SD. Then go on LauncherPro and set them again like you did on the previous one. You wouldn't have to uninstall/reinstall LauncherPro.
