[Q] I9000M and Voodoo or OCLF lag fix

I was reading forums about lag fix.
I wanna install one but it seems like possibility of bricking phone after installing lag fix is higher in I9000M (Bell model) than any other galaxy s models.
Is there reason for it? Can anyone share their experiences?
Also, I read somewhere that JH2 fixes the lag. Is that true?
I was doing benchmark but never got past 950 with quadrant....

I had no problem with OCLF until I did an upgrade of th app trought android market. Then OCLF didn't recognise that I had a lag fix install and I tried the option to repair the fix and it made my phone lag like hell. Then I tried to flash and repartition with odin to wipe this but I surelly made something wrong cause it bricked the phone. I had to buy another one used over kijiji.
Been using OCLF since then and I didn't had any other problem. I even uninstall it completly a few hours ago cause i want to try froyo. I think it's safe but don't try the repair option ever and try to install and uninstall the fix with the same version of the OCLF to avoid recognition problem.

Sorry i didnt really get how you bricked yours. So were you upgrading any app with lag fix? Do you mean you shouldnt upgrade any app after you installed lag fix? So to upgrade, i should uninstall any app completely then re-install new version?
Thats one downside....

I'm not sure how I bricked my phone but it's related to the re-partition option in odin and me flashing a froyo firmware. I did this with XXJPH and it was after the problem with OCLF.
What I'm sure of, is that OCLF (the app from the market) didn't recognise that my phone had a lagfix and didn't allow me to un-lag fix it. So I tried the option to repair the ext2 tools and it failed. After that the phone was really lagy and a lot of forced close happened. That why I wanted to repartition with an odin flash.
The probleme is that I tried with the only firmware (at the moment) that requires to never use this option. I should have tried to go back to UGJH2.
For OCLF i'm gonna try something. I have an update showing in the market so i'm going to install the lag fix whit my application and then I'll do the update to see if it can still see the lagfix. Maybe it was my fault in the first place. You'll have feedback in 5 min.

Ok I confirm that everything is working fine. See screenshot. I don't know what was the problem I had but it seems to work fine and there is no problem to recognise the lagfix once updated.

Hi, my SGS is now running Froyo, and all apps and settings are restored. I thought that I should reinstall OCLF 2 again to maybe get some more juice from the file system, and after installing from Market and rooting the device everything seemed fine. But during installation of the actual Lagfix, I noticed an error during the "dd" command (unable to mount device, device busy, or something like that). I was offered to send the log to the developers which I did. I tried to run it again, but get the same error message. But this time the device was hanging hard and nothing I did made the error screen go away. So I removed the battery and restarted the phone. Now when I enter the OCLF app, I can only select the "Unroot device". Both "One click lagfix" and "Undo one click lagfix" are red and not selectable.
If I look (with Linda filemanager) in the root filesystem, there are two zero length files, /dbdata and /data, both created at the time that I tried to apply the lagfix. Do I dare to remove these to and see if they are causing the deadlock?

Try removing your SD card, and then run the OCLF

If OCLF can't remove the lagfix you'll have to flash a firmware with Odin and repartition you'r internal sdcard at the same time. Just be carefull and chose a firmware that you can use to option to repartition with. Usualy all the 2.1 firmware are compatible with this option.
Then flash back with your desired froyo firmware and try CF root before you start OCLF. OCLF should not be use to root 2.2 device maybe your problem was caused by this but I doubt it.
I used OCLF with XXJPM without any problem but I flashed JPM over a clean 2.1 firmware (fresh flash with repartition option and no apps install).

Did not help. Do/Undo both still red.

I will first find a tool to backup all settings and apps before trying a re-flash. The question now is - is it worth to go through all this just to get OCLF up and running.

Definitely!! Try Titanium Backup. It can backup all your apps and data attached. Moreover it'll be able to re-install them without prompting you for every apps. You just start the backup before the flashing and start the restore after and let it go by itself. But be carefull to backup only user apps if you go from 2.1 to 2.2 or vice versa as it's gonna cause a lot of force close if you try to backup and restore system apps that are not right for your android version.
I'm running with OCLF and I can assure you that you won't regret. No more black screen before you launch an app. Installation and or uninstallation are almost instant so your update are done faster over the market.

[Q] How to re-apply Voodoo without re-flashing it again?

Hi peeps, sorry if this is a repeat or nooob thread.
Here's how it went:
I flashed JM8, then to JP6 Froyo, then I rooted using CFroot, then I apply Voodoo 5.
All is well until I apply Voodoo. The market was lost and my quadrant is about 1540 but still kinda laggy.
So, I reflashed everything once again.
I "disable_lagfix" on Voodoo and went through JM8, JP6, CFroot again.
After completion, I deleted the disable_lagfix file.
I played with the phone the whole day and thought I had Voodoo enabled. But my quadrant is only 977 now.
So, do I have to Odin flash Voodoo again? I want Voodoo but I don't want it if it clears up my settings and apps. Yeah I can restore them but it takes super long time and I don't want that.
Suggestions please.
Thanks to mods for moving it here.

[Q] Lag fix removal and upgrading to 2.2.1

I installed OCLF on my phone (Froyo JPO) and tried to remove it in order to upgrade to 2.2, I think it didnt remove the lagfix right though, as the option to apply the lag fix, and the one to remove the lag fix is no longer available. (I cant remember if it specifically said it failed or not.)
I saw somewhere on this site that you first have to install some other rom, or to just select something else in ODIN if updating with lag fix still enabled. Also, should I uninstall all apps with root access before unrooting? And can I backup apps with titanium backup in order to restore it if I have to completely wipe my phone?

use quadrant to check your score.. if its more then 1000 the lagfix is still enable.. my advice is to flash only if you are sure that it is disable...
if i am not wrong, OCLF can say the reason why a function is not avaible, maybe your battery is less then 40%
for flashing it is not neccesary to unroot..

Youre right, it does give the reason. When I try to remove it it says that I dont have the lagfix installed, and if I try to add the lag fix, it says that I already have another lag fix enabled, which I dont. Obviously something went wrong somewhere.
Should I just try to flash 2.2.1?

the exact error messages are as follows
when i try to remove lagfix: "You do not app0ear to have a V2 lagfix installed! (free space on /data does not match /dbdata/ext2data)"
When I try to add the fix: "You already appear to have another lag fix installed! (/system/bin/playlogos1 less than 5 kb)"

So you still dont know of the lagfix is enable??.. check your quadrant score.. if this is below 1000, this will mean that the fix is disable, so you can start flashing..

I just assumed it wasn't applied anymore and installed update and it worked. Lucky me I guess haha, thanks for help

[Q] Lagfix options

I have rooted my phone using the Onclick rooting software, that seems to have been a success.
However, I tried using teh OCLF from market to lagfix it but nothing seem to have happened in the 30mins I let it do its thing. THe progress bar goes full then start again, and does this repeatedly. And after reading around some people say that's now out dated and other lag fixes should be more suitable
So, now that my Samsung G S is rooted, what options for lagfixes do I have?

Hi, im asking the same questions
Hi, i am in uk running stock froyo 2.2, I have rooted my phone using Z4root, but I want to put a lagfix on, I have read that OCLF isnt very good anymore, and voodoo you have to install a new rom and im not brave enough to do anything like that so which is the best lagfix i can use and i have heard about overclocking what does that mean? thanks in advance
can anyone help us please

Besides the fact I dont know whats a Samsung G S and no idea what your ROM version is you could do what I did. But depends on your ROM and SGS version!!!
But its on all your risk. Read manuals and warnings to the kernel and the app. You have been warned (I have done this on 2 SGS mine and my friends till now , he has 2.2 stock rom and I 2.2.1 stock JPY too)
Took the neldar kernel flasher , backed up my stock kernel.
Then flashed the speedmod CWM version with the kernel flasher, kernel you can find in the speedmod kernel thread.
Applied the tweaks and lagfixes (ext4) from the recovery. done
and that was it. btw when you do this, try to run the rom WITHOUT the lagfixes, just with the new kernel so you can easily get back to your stock. If you want more, then go to the recovery ULK options and do the recommended tweaks from there. If you still need it, then apply the lagfixes (always backup and always on your own risk)

Not sure you have to install another rom, but I do not know the the original voodoo kernel . Maybe you could try with the one I suggested up there.Btw there is more kernels to choose from, depends on your Galaxy Version and ROM.
Overclocking is nothing you should be concerned with yet I think there is a pretty big speed jump from stock to custom kernel, then from custom tweaks and also to lagfixes. If you are not satisfied then you can try that. OC should make the phone faster. In my opinion though the 1GHz is enough for the phone. With OC come some risks (heat, battery usage, stability)

Last night I managed to get the OCLF working on the phone and noticed improvements. Now that I have a lagfix working, will OCLF be alright to leave on there? Or do you still recommend going to somethign else? (I didn't quite understand why OCLF is being considered out dated anyway).

Install the new version (2.2.1) and lagfix is of no need anymore.
Completely satisfied with a smooth running Galaxy now.

Well keep the lagfix you have now. If you wanted try something else you would have to undo the changes you have done till now. If it works and you like it keep it..
To plexat: yes the 2.2.1 it's sufficient in speed.
In my case though I had to do already 2 factory reset once cuz the phone didn't start at all and in time even the 2.2.1 became slow. I installed the custom kernel though just for the sharpness fix but was surprised with the lower battery usage and speed. There is still a big speed jump from stock to custom

thankyou for your help, ive got the kernal flasher and kernal thread but can you just confirm for me what I have to do with the kernal thread sorry but ive not done this before and really dont want to damage my phone thanks again Karen

Ok man, first of all. You have stock 2.2 but which phone exactly?
In the kernel thread, is written for which phones it is and also for which ROM.
So if it fits yours. You can try what I wrote you somewhere up. Backup, flash the CWM version etc.
First make sure though if you have the correct kernel for your ROM and phone. AND you shouldn't have any other type lagfixes applied.
Thats kinda all. What you can do if you have root, without any trouble, is backup your kernel with the app. Then verify if other things fit. And you can try to flash a custom kernel.
EDIT: Why are you still on 2.2? I mean UK had as one of the first 2.2.1 and plexat is right. 2.2.1 is faster and smoother as 2.2 ? If you dont have any lagfixes or other custom things applied you should kinda update to 2.2.1

Hi Pagot, I checked I had the right kernel and stuff and YIPPEE ive done it, my heart was in my mouth but i took the plunge and it now says i have the kernel above, it does seem more responsive and quicker although the benchmark still says the same? the reason I have still got 2.2 is because I have a branded o2 phone and they havent released it yet for branded phones and i am scared to try and flash it to 2.2.1 is there anything i can now do to speed it up anymore ie lag fixes and things thanks for your help

Glad it worked for you
Well not sure about upgrading the rom with a custom kernel. Am new at this too . So dont flash a rom yet.
From what I asked in the speedmod kernel thread. It should be safe to put back the stock backup kernel you made with the app and then to update if its out. Thats just for 2.2.1 upgrade for you in the future. The condition is however no lagfixes applied!!! If you have them applied it can and will probably go bad on the update!!!

Ok please dont look at the score. Mine is actually worse as on the stock kernel if you are talking about quadrant. They are irrelevant.
If your phone feels right, leave it as it is
If you want to tweak it little more. Get to the recovery and there are some tweaks,should be still safe to make. They are marked as recommended in the ULK options.
I wouldn't suggest yet to apply a lagfix. Try it how it feels now. If it starts getting bad and laggy etc. Then experiment with that. I had a lagfix but reverted back, for me the speed is sufficient how it is now
Since you have now CWM you can even backup your whole phone.
If you dont know how to go to the recovery the 3 button combo. There are many nice tools in the market for that. I personally use SGS toolbox/tools, in it is a shorcut with reboot to recovery.
When you are there. the BACK button is actually like OK so beware of that!!! You navigate with the volume button UP/DOWN and confirm with home or back.

Thanks again, been in and enabled tweeks, just so as I no, I noticed in recovery there is a lagfix option is this where i go to apply this and if I do it how do I disable it if I want to
Also you said I could backup my phone now how do I do this Thanks again

Wow my phone is really speedy now thanks for all the help I've now flashed kernel tweaked and applied lagfix and all is well I've backed up my phone as well

Ha seriously glad for you . One day you have no idea about anything, the next day you run a custom kernel with lagfixes and tweaks.
When you get to it, its kinda not so difficult. (It took me kinda a half year )

How true. Just in case get familiar with Odin. Having fun with flashing by CWM can sometimes result in being stuck. Knowing how to use Odin and having all necessary files on your computer should give you some sense of security.

[Q] Galaxy S upgrade to Froyo from rooted and lagfixed phone

I have a Galaxy S which i rooted and installed a lagfix on. I think it was Ryans OCLF i used for the lagfix.
I want to update to the official Froyo available from T-mobile via kies but having lots of problems getting it to connect (as everyone does). I have backed up contacts etc. I havent bothered backing up apps as i just wrote down the settings i have in each one and will just reinstall them after the upgrade.
What im planning on doing was completely resetting the phone back to factory settings and wiping it altogether so i have a clean phone to do the upgrade.
The problems im expecting or want to know how to avoid is with the root and lagfix i have installed. Will doing a factory reset or other reset (hopefully somebody can tell me another way of resetting) get rid of the root and lagfix or do i need to do something manually before wiping the phone? I know of something about the lagfix creating partitions etc so would a factory reset cancel the lagfix or would it cause all sorts of problems?
How do i go about removing the lagfix and resetting to the standard software that came with the phone? Also i have apps that require root so if i unroot the phone will this cause problems when they try to start or will they just not work and not be an issue?
Im not running any custom roms just the original one that came on the phone.
Sorry for all the questions and a rather long first post but im hoping to do this soon as the phone is running like a bag of smelly brown stuff lol.

Disable the lagfix first and then wipe. Root will not go away but I dont think that would be problem.PS. If I would be you I would just use odin to upgrade, there is plenty of good guides including how to use odin

Undo lagfix before any firmware upgrade .Then factory reset then go to Kies .
Remove lagfix as per the instructions with whatever lagfix you used .
Unroot not a problem its only a user administrative rights fix giving you greater access .
Personally i undo anything i can before an upgrade .
jje

Yes i would definitely undo everything before upgrading its just a question of how i do it.
I used Ryans OneClickLagFix app that was on the market at the time but now it has been altered because it allowed you to root and google didnt like this. I still have the original version i downloaded on the phone so is it just a case of clicking on "remove lagfix" and that will sort it?
Also if the root remains on the phone after i have wiped it, will this cause any problems when i put froyo on it? Is there not a different method or file for rooting froyo to the one i have used on 2.1?

on "remove lagfix" and that will sort it?
Correct .
jje

Also click Remove Ext2 Tools, and the go into the Scheduler changer and return it to CFG and uncheck the tweak buttons, if you messed with any of that.

In which order should i do all of those?
Should i remove the ext2 tools and return cfg settings etc to default before i remove the lagfix or after?

So just a quick update.
Something went totally wrong the other night on its own. This is before i had even thought of upgrading that night. Was sitting on facebook happily playing away when it started force closing within a few seconds of opening. Tried to open the market to reinstall the facebook app and the market force closed in a few seconds. It did this with every app including the email and phone etc. Even the RyansOCLF would forceclose so i couldnt remove the lagfix or unroot etc. All my settings for apps and launcher pro settings had disappeared. Only a couple of icons i had set on the home screen of launcher pro remained but i couldnt use any of them. All my phone logs were there and so were my texts etc but everything else had reset. When i tried to reapply some of my settings and then restart the phone, when i had finished the restart the settings i had reapplyed had defaulted again. Disaster!!
The only thing i could do was run a factory reset from the options menu. I crossed my fingers hoping this wouldnt brick the phone and alas it worked perfectly. Sorted out kies and connected the phone and installed 2.2.1 android. The lagfix had been cleared by the factory reset. I keep wondering if this is why i had so many problems with it taking ages to start up before. Maybe because the lagfix never really worked properly it never fully rebuilt the file system so was removed easily? Although the benchmarks were coming up double the speed of the fastest device on the results so not too sure how it was performing so fast with a duff lagfix...who knows. Anyway got it all up and running and rooted and lagfixed using the voodoo fix. Stuck launcher pro on setup everything. Got the apps i previously purchased reinstalled and restored any apps i wanted from titanium backup. Works like a dream and alot better memory usage aswell.
Thanks for all the help guys but it seems although i didnt follow any of the instructions you all posted (not out of choice...just because the phone physically wouldnt let me) it seemed to get the upgrade done without any problems.
