[Q] [KERNEL] SpeedMod Captivate [K12T HPCall VoodooSnd4 SharpnessFix STABLE] on I896?

Hello,
Sorry to sound like a complete noob in advance!
I have a new Samsung Captivate I896 on Rogers in Canada. I have ryans OCLF lagfix installed atm but i'm really interested in flashing this rom (will be my first one) and am wondering if it will work on this phone.
Also, is it just a backround fix? Will I still be able to use launcher pro, and will my phone still look the same with Froyo 2.2?
thanks in advance!

Speedmod is not a ROM, but a kernel.
As to your other questions, you have a LOT of reading left to do.

Agreed. Just to be save do alot of reading before attempting anything really lol. There are stickies in the Development section start there.

Ok so I did a little more reading. I896 and I897 are essentially the same. I'm not flashing a rom, just a kernel, so there should be no issue with the 3G problem mentioned in the wiki.
It won't change my rom or anything about the device other then how the filesystem works.
Thanks!

Hi, I'm pretty new here too, and I have to tell you that know one will give you a straight answer. There's a lot of' tribal knowledge', and it seems that people would rather teach you how to unbrick your phone than to flash it without issue.
First of all, hook up to Samsung Kies and update your phone to Froyo. If you are on Rogers it's an official update, don't worry about flashing any other roms yet.
Next, Use the option in the OLCF to unlagfix.
Next, you will need to root your phone. OCLF is practically obsolete, as the developer does not update anymore. Your best bet is Superoneclick. Read all instructions first. It is very easy and effective.
After you have the phone rooted, you can now install Titanium Backup. This will save all of your apps, contact info, settings, virtually everything on the phone, it will save them to a folder on your external SD. drop and drag this folder to your desktop in case anything goes wrong. I never had a problem.
You should backup your kernel. I used Neldar's SGS Kernel Flasher. It will save your kernel as an 'update.zip' in your root folder. Drag this to your desktop and put it into a folder called 'i897 orig kernel' or what have you, in case something goes wrong. I never had a problem.
Now you can flash SpeedMod. The developer's website, which is linked to in the thread's first post, will walk you though it. You will first need to install ODIN. The SpeedMod developer has a step-by-step on how to flash SpeedMod using ODIN on the developer's page. Make sure you choose a Speedmod Kernel that is intended for the Captivate, not the I9000, and that you chose the one for ODIN, not the ClockWorkMod version. Follow the steps in the Developer's page.
When you have done that, reboot into recovery mode and you should see Green Text. From here you can enable the lagfix and other tweaks. use the volume keys to select the option you want and the power button to select. under the options, it will show you which tweaks you have enabled or disabled.
Remember to select the most stable SpeedMod release, the one that is posted in the Forum (K12U-T4) is a TEST VERSION, hence the 'T'. The latest stable version as of this writing was K12T, as posted in the developer's page. I have had great results with this one.
You may find that you don't need to flash a custom ROM, I have found this setup very satisfying.
Good Luck!

Wow,
Thank you so much clemmie! That's was succinct and very helpful, especially the part about the proper way to back up my stuff.
I uninstalled OCLF just now, and it seems my phone runs at the same speed (aka fast) as it did with the lag fix installed!
Going to flash this kernel tonight or tomorrow, I'll let you know how it goes.
Thanks again!

Good to hear. There would be a lot less smoke and mirrors if people would just be straightforward and post step by step instructions with links, to give people what they want. I hope what worked for me will work for you, and I encourage you to share what you learn as well.

Kernel flash done! Screen is initially very different looking thanks to the amoled mod. Success! Backed up, thanks for all the help.

hey clemmie,
i heard that there's some issues with voice quality due to the Speedmod kernel being initially i9000-based and that it's recommended to flash a i9000-based modem. Are you having any issues with using a stock i896 modem or do you recommend something else?

Yeah, that is true, but I haven't had any problems with the stock modem. The phone works as well in-call as any other I've owned. I wonder if there is a difference between the AT&T build vs. the Rogers build. It seems that it's the AT&T folks that have issues.

Hi,
I've been wanting to do this but I'm a bit wary if this will put the ATT splash screen on boot as well. Also, I like how my phone looks like now with ADW launcher and beautiful widgets installed, I'm just wondering if installing this mod would change my appearance settings too.

Are you on Rogers? Earlier versions of the SpeedMod kernel had the AT&T splash screen, but newer versions have a simple black screen similar to the stock Samsung boot logo.
Installing the SpeedMod kernel will not change the configuration, apps, or settings of your apps. There are some settings that you can tweak in recovery mode but they are mostly file system tweaks. You will however notice that screen resolution is sharper. Your phone will run smoother and more efficiently with better battery life. You can still flash any custom or stock ROM with SpeedMod or without SpeedMod.

Yes I am on Rogers. However, I can't seem to find the stable version K12T that you mentioned on your instructions from the developer's page.

If you click on the hotlinked 'SpeedMod' in my 'tutorial' post, it will take you to the XDA page dedicated to the SpeedMod revisions. Right now there is a 13A Test version posted, but the latest stable version is now K12U. If you click where it says 'more info and downloads', it will take you to the developer's(Hardcore) blog, 'Tourist In Paradise'. The revisions are listed there. I would bookmark this page and check back frequently, as Hardcore is constantly updating. However, I'll link you to the latest stable release for ODIN, K12U:
https://docs.google.com/uc?id=0B-3n...WJmNTUtZDVmNThmMmNhZTRm&export=download&hl=en

Thanks for that! I just did this and although it didn't show the ATT boot screen, it shows the Galaxy S I 897 screen after the I 896 though. Thanks again!

Glad to hear you had success. Not so hard after all, eh?

After using this for a day or two:
I can't believe how fast my phone is. I thought it was fast before with (and then without) the oclf. I can barely keep up!
Battery life seems improved.
Screen is perfect. The lowest brightness setting is much better and more comfortable for low light usage.
I lost 1000 points off quadrant, but quadrant doesn't matter.
The only real downside is call quality took a hit. It's a bit static-y and echo-y.
I'll look into this though and see if I can find a solution, but if you have any tips let me know.

Looks like you are a candidate for a modem flash. Let me know if you find something that works, there is a lot of info on swapping modems for SpeedMod. Maybe I'll try one too!

Hey clemmie (or anyone), if I want to install voodoo lagfix - how abouts would I do that if the SpeedMod kernel already comes with / is based on sztupy's Universal Lagfix (enhanced) and if voodoo is a kernel itself (unless I'm wrong about this)?

If you flash the SpeedMod kernel, voodoo lagfix comes integrated with the kernel. It's a master of enabling it from the recovery menu.

[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

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] Getting Supercurio's I896stock+voodoo to work after SpeedMod

SO, earlier today Supercurio put together something special for those of us in Canada on the i896- a stock Rogers Froyo kernel with voodoo injected into it. Following logic, those of us on the stock Rogers Froyo should be able to have our cake and eat it too: a kernel modified especially from Froyo, intended for the Captivate, with voodoo lagfix but without the need to reflash an i9000modem or kernel. Here are the files:
Kernel: stock Rogers Froyo i896 w/ voodoo injection
Modem: Stock Rogers I896 UXJL1 Modem
Before trying a flash, I unlagfixed and backed up via Titanium Backup.
First I tried the kernel flash. I knew it wouldn't work with the modem, but I flashed it first to make sure there were no issues.
Rebooted into recovery- RED SCREEN
I did not enable the lagfix at this point. Just a straight reboot.
Regular boot screen; Rogers logo; Samsung Splash screen- then everything goes black. The home key buttons will light up and never go out if pressed. The phone stays like this until I pull the battery(I waited 25 min before I gave up).
I have tried various configurations regarding flash order(kernel/modem), I have repartitioned the card, factory reset before starting, everything I can think of, but this kernel won't boot past the splash screen.
However, when I revert to SpeedMod kernel(k13c) everything goes back to normal.
I would have thought I could flash this stock kernel over the i-9000 based kernel with the lagfix on both without issue, clearly I am wrong.
Can anyone see anything in my process that is inherently wrong, or even better would some other brave soul with stock Rogers Froyo be willing to try a flash? I wouldn't bother if this is your first crack at it though.
Thanks in advance to all who can help out.

So after wiping all caches and factory resetting, I get the following message at my Red Recovery screen:
E:Can't mount /dev/block/mmcblk1p2
(File Exists)
Is this important?

I get that all the time. No idea what the hell it is and have had to manually select my GSM bands when I flash a new rom or wipe dalvik cache since it started. Other then that no problems seem to be caused by it, for me.

Call off the dogs- after I installed the driver package that was included with Odin 1-Click I managed to get a master clear and a flash to the AT&T stock.
I must have spent 3 hours installing different driver packages today.

A shame it didnt work out smoothly. I'd be interested but am far too new to risk the troubleshooting..

Well, I have some very good news. This little kernel seems to be pretty special. After getting myself back to Rogers Froyo, I have done a few tests. I am getting very solid Linpack scores of 15-16 mflops and Quadrant Standard scores of 1400-1500. Using CPU benchmark, we have scores of about 725 ms @ 1000 hz and 700 ms @ 550 hz.
These scores are very solid and are about 20-25% improvement over stock Rogers Froyo Kernel.
This is promising as the kernel is a native Captivate kernel and could do a better job of servicing the many Froyo ROMs out there in terms of simplicity and stability.
The stock modem still needs more testing in terms of gps fixes and accuracy and data speeds.
I'll get back to you about those shortly.
If you have thought about staying on Rogers Froyo, this would be a good start for improvement.

I would highly recommend this Kernel!! All the above benefits, plus fantastic battery life. The stock modem seems fine, although I've had better data transfer speeds and GPS locks from JL1 kernel, but this stock modem is perfectly fine.
Would love to see anyone else's results as well!

I like what I see so far. I am getting 1575 scores on quadrant (I know it doesn't mean much) but overall lag is gone.
I was a little freaked out this morning as the Rogers network was dead here this morning and I thought maybe I had done something with all this to kill cell / data. But everything cleared up after a few hours and I was back to normal.

Outcast, were you able to flash this custom Kernel without the issues that Clemmie came across? Much like phrenicthenub, I'd love to see the performance increase without the current bugs of custom ROMs, but I don't think I'm competent enough to troubleshoot if it all goes to hell.

As long as you disable any lagfixes and return any O/C or U/V kernels to normal you won't have these issues. Everything should work fine.

Did you guys do the 3e recovery fix first before being able to install CWM?

Hi guys... So i was trying to get SpeedMod to work with a i9000 modem like JK4, but my bluetooth is always noisy...
Right now, i have:
Latest SpeedMod kernel with LagFix enabled
JK4 Modem flashed.
What do i have to do to get this Rogers Supercirio's Voodoo kernel and modem ?
Thanks.

Elisha, I just took the plunge and got these flashed. Definately do the e3 recovery fix before setting up clockwork or anything else. That was the one part that gave me any trouble, but as soon as I got that sorted, everything went very well.
I'll try to pay attention to how things seem to perform and post my findings. Thanks for the encouragement again, Clemmie.

First you will need to boot into recovery and disable your lagfix. Back everything up with Titanium Backup. Download the files above to your root folder and reboot into recovery again. Using cwm, use the install zips option and flash both the kernel and the modem. Reboot yet again into recovery, clear your caches, then enable the new lagfix in your cwm options. It will take a while to convert your partitions from rfs to ext4, so be patient.

Thanks Clemmie,
I disabled LagFix from cwm and the speedmod kernel, rebooted, flashed modem with original JL1 modem, and then reflashed kernel with stock rogers froyo. backed everything up with Titanium backup. So i am currently back to stock, with a backup.
cwm is not in my recovery menu now, so if i use ODIN to flash the .tar version of supercurio's stock+voodoo kernel, does it contain cwm ?
ODIN with this kernel should work and then enable lagfix on first reboot by converting to ext4 right ?
Thanks alot, i am just starting with all this and want to make sure i understand everything before i take the plunge.
Thanks.

Thanks ! i'll try that a little later... i'll let you know how it goes...

Well, so far, this Kernel seems to be the best thing to ever happen. I consistently get a score of 1501 in Quadrant standard (not from a fresh boot or anything, and running beautiful widgets and things, so I don't know if that makes a difference. I know with most benchmarks you're meant to close as much as possible, etc) and things just seem to be nice and smooth overall. On top of that, the battery life is, all of a sudden, seemingly PHENOMENAL! All whilst using the stock ROM. Either one of those benefits alone would have made the flash worth it. This is the way this thing should have run from the beginning.
I'll test out how well the GPS works, and try to pay attention to my signal strength with WIFI and calls and report back.

Thanks I figured as much as I had to do the 3e fix after I accidentally upgraded to the official Rogers Froyo the first day I got the phone.

Ok, so i have used the tar version with ODIN3 v1.52 to flash stock+Voodoo-Froyo-I896-UXJL1. As i said, i was on stock kernel with stock JL1 modem.
Flash went great, took about 5 seconds, then rebooted. First reboot took about 7 or 8 minutes with a robot voice telling me the different steps it was in...
Everything workd without hickups... This kernel works realy well and speed is definitely there !
Thanks for the help guys...

[Q] Ok to use modded kernel with stock froyo (KB1)?

Is it ok to use a modded kernel (like paragon) with a stock rom (KB1)?

I believe so.i think as long as you use a 2.2 kernal. I'm probably wrong though. Lol
I kill coneys, not phones.

The various release notes imply that it is possible but since its my wife's phone I dont really feel like getting killed for bricking it.

Have no fear. If you follow the instructions you will be totally impressed with the performance improvement. I am running totally stock with the exception of my stock kernel with voodoo lagfix and you can't beat it with a stick.

Which kernel are you running?
Edit: Nevermind, just read your sig file.

Cognition 4.x is basically stock Froyo with a lagfixed kernel.

If you don't want to venture too far from stock, you could use Supercurio's stock + Voodoo lagfix kernel for KB1.

You can flash the CWM version using SGS Kernel Flasher. It'll take a while for the first boot up, but you'll get audio prompts that it is working. Just take your typical precautions...backup, blah blah blah.
Works great with KB1.

I actually have CWM flashed onto her phone from installing PlumbBob's GPS fix so I could flash it with CWM. Thanks.
My main reason for flashing a different kernel was because her battery life is lousy compared to my phone with Serendipity and Paragon.

IMHO, the battery life has been great since flashing that kernel. I haven't done any official logging or anything, though.
And the difference in speed because of the lag fix is unbelievable. Incomparable.

You can flash the CWM version using SGS Kernel Flasher. It'll take a while for the first boot up, but you'll get audio prompts that it is working. Just take your typical precautions...backup, blah blah blah.
Works great with KB1.

I absolutely agree with you lactardjosh.
Suoercurio has done a fantastic job in creating these kernels.
I flashed the V+KB1 the other day and my devices runs as if it's on a silicon base. Smooth - Extremely responsive - No difference in battery life - and most importantly - All of the features that are supposed to work...do!
Peace-

Edit: Installing that Kernel didnt wipe your phone did it?

Flashing the kernel did not wipe my phone. BUT, you should definitely do a back up before flashing it. Just good practice.
The first time you boot up after flashing the kernel, it will take a while to finish booting. It'll stay on the AT&T World Phone splash for quite a while. You'll get a digitized voice telling you that the Voodoo lag fix is running and it'll give you an estimated time to complete it. The first time I did it, I couldn't understand what it said, but after messing up something else and having to go back to 2.1 and then upgrade to 2.2 again (which did wipe my phone), I realized that the first time it had told me it was going to take 10 minutes to enable the lag fix. The second time around, it took 2 minutes because there was nothing extra on the phone since it had just been wiped. So, depending on how many apps, etc, you have installed, the lag fix will take a more or less time. Let it run, find something else to distract you from how long it is taking.

I have enabled the lagfix on my phone. My wife has a LOT of apps on her phone so it will take awhile. I backed the rom up using rommanager and copied the Titanium backup directory off to my home computer.

I installed the Supercurio kernel last night on my wifes phone so it will be interesting to see whether the battery life gets any better. The phone should run smoother though.

My Captivate runs great on the KB1+Voodoo Kernel from SuperCurio!
The performance of this Kernel has actually kept me on the stock ROM (for now)

I told my wife that her phone should be snappier now but the battery life may stay the same. Also told her to drain the battery down to nothing, charge to full while off, unplug and plug back in, wait until its full then unplug and turn it on.

[Q] CM7 Nook Kernel

I'm sorry if this is has been answered before but i'm a noob, but an actively learning noob =) There is so much information in these forums but it can be highly overwhelming with so much info out there and hundreds of pages, it's like finding a needle in a hay stack.
1. I'm unsure exactly what a kernel is.
2. I am currently running CWR 3.0.0.5 w/ (Nookie Froyo Custom 0.6.8). Can I / Should I update to CWR 3.0.1.0 even if I stick w/ Froyo? Will the update overwrite my system forcing me to reinstall everything?
3. I saw something about Tablet tools (or something similar in name). Does that get installed in CWR just like Google Apps? Do I install before or after the ROM (Froyo Custom / CM7)?
I would like to go to CM7. But am curious about different Kernels such as Darlingtons OC. Any other recommendations? I currently use SetCPU at 1.1 in Froyo w/ no problems.
Thank you for your help in advanced and to all the amazing devlopers out there!

First off, read more before attempting anything. I cannot stress enough that you should always be sure you understand exactly what you are doing, even if you're unsure how the process works, otherwise if something goes wrong and you weren't sure what exactly was happening you'll be kicking yourself later.
The kernel is the part of an operating system that actually makes the software and hardware talk to eachother in a sane manner, read: it makes everyone play nice hopefully. CM7 does include one in the image but if you read further on how to flash stuff you can replace the stock one with an overclockable version if you'd like.
Some of the documentation I've found can be a touch confusing if you're new to Android to be sure, I'd reccommend reading thinkgs a few more times and asking questions about specific tutorials, it will help get you started in the direction you'd like to go.

OP Modified question to be better suited, new response to match:

Kernel, in OS terms I answered above, in Android terms it's basically the same except how it is updated vs on say a Linux PC is different, isnted of just installing it normally you have to "Flash" a separate file, more on that in response to #4.

I have CWR 3.0.1.0 and it works great, I am not aware of it overwriting previously installed ROMs but I'm not a CWR dev so take that with a large grain of salt.

Link to the thread in question, I'm not sure what you're asking about on this one.

CM7 comes with its own kernel but Darlington's OC kernel works amazingly well, he has packages that you can flash via CMR just like you would GApps, just make sure you grab the one that is right for your install of CM7 (SD or EMMC depending).
Hope that helps
