is upgrading kernel a must for froyo? - Motorola Droid and Milestone Q&A, Help & Troublesh

Hi all,
Just my thought, is upgrading kernel a must for froyo? If that possible maybe we can upgrade froyo even bootloader is locked.
For example, my ubuntu 10.04 run well using kernel from 9.10

By technicality, no, a new kernel is not required to get most of the changed applications to run on Eclair, though, your forgetting what Froyo was. It was a optimization release, and therefore the kernel was changed heavily and modified extensively to improve performance and stability. That and it has a completely different version of JIT running on it. Basically, if you want Froyo in all of its goodness, your going to need to change the kernel, which is impossible right now. Just sit back and wait for the update.

I'm no Linux expert, but isn't it possible that many of the features that we're looking forward to in Froyo (such as the increased speed, stability and other system-level tweaks) are actually part of the kernel?
Sure, parts like Apps2SD or tethering might be ported without the whole kernel, but I'm guessing that the kernel modifications play a big part in making Froyo Froyo...

Dragon ROMs, direct to ext4 install, voodoo5

What is this? It's an experimental ROM install setup that avoids the use of RFS entirely. The install basically pre-voodoo's your phone. If you know you want voodoo, this is faster than installing then doing voodoo, but it's a little more complicated. Not much, but be warned. It avoids the use of RFS durring install completely, so no RFS corruption to worry about.
The ROM itself is mostly untouched. The kernel is my Dragon Kernel, i9k based, so it will eat your battery (froyo only, eclair is better as we have source). I can get about 12 hours out of it. Buy a charger.
The new version is a 1-click install. It installs the kernel, reboots into it, then auto-installs the ROM. I tested it coming from JFD without issues.
These are based on voodoo5 beta code. Curio is releasing voodoo5 stable here soon, and I'll post an updated no-wipe kernel flash for that.
The ROMS are Team Whiskey Obsidian, Onyx, and Fusion. I changed the install procedure and the kernel out, the rest is as they made it. I take no credit for the ROM. Please post bugs here however, so I can make sure they are ROM bugs before letting TW know about them. I'm running the Onyx version as my daily driver. There has been some private beta testing, and they seem stable, but do have Odin handy just in case. I have installed over the top of various ROMs, but the safest way is probably to come from JFD just to be sure.
ALL THESE ROMS WIPE. NO, I WON'T CHANGE THAT.
Obsidian V5b: http://www.tabbal.net/files/Dragon-Obsidian-Installer-v1.0.zip
Onyx 4.2: http://www.tabbal.net/files/Dragon-Onyx-Installer-v1.0.zip
Fusion Final: http://www.tabbal.net/files/Dragon-Fusion-Installer-v1.0.zip
NOTE: THESE INSTALL VOODOO. ALL THE USUAL VOODOO PRECAUTIONS APPLY, IF FLASHING SOMETHING, DISABLE IT FIRST.
The latest voodoo stuff seems to play nicer and I have flashed things from clockwork without bricking, but just be warned.
Updates:
Kernel with the stable voodoo5 release. Should work with any froyo ROM, does not wipe.

I can conform that these are indeed working. And they work beautifully. I'm evening thinking about going back to some voodoo love.
Love your work ttabbal.

Hmmm...cool. Might have to try this with Axura 2.1.

Curious! So what's the true (RFS free) Quadrant score for Vibrant?
Can we have just a kernel flash that will convert all the partitions? supercurio's i9000 flash doesn't wipe the data, it simply tars it and then untars it back once the conversion is done to each partition. Thanks for the hard work.

The post is about the ROMs, but yes, the kernel update I'm about to post will convert an existing system to ext4 on reboot with the just released voodoo5 stable code.
It's the custom kernel I reference in the OP. If you want more than about 12 hours off charger, don't install it. I'm going to look at Eugene's recently posted source to see if I can implement whatever he did to get the kernel sleeping better, but no promises. And reports are kind of mixed last time I looked at it anyway.
When Samsung gets around to releasing source, we can do better. Till then, give me a patch or don't complain about it.

Nice. I'll hold off trying this with Axura 2.1 until this posted, then. A battery life of 12 hours is fine in exchange for what Voodoo will provide in return.

Sweet, thank you.
i flashed this on obsidian v5 beta w/ jk6 modem and it running like a champ. however, you were right about the battery life
thanks for posting it before hand. i appreciated.
Love the new kernel would u consider an overlook version? Eugene 1256 is so snappy but it corrupts data. That speed plus voodoo is crazy fast. Real 2000 + quadrant.

Froyo Kernel on Eclair?
ttabbal,
I did not know that a Froyo kernel could be backward compatible to Eclair. Is that the case, given that your Dragon 2.0 incorporating Voodoo 5 Stable will work with Bionix Fusion?
Please help me to understand this.
More to the point, I am on Bionix 1.9.1. Would Dragon 2.0 w/Voodoo 5 Stable work on my setup?
Thanks,
Bruce
Would love to use this, however i cant seem to get anything to install from the market no matter what i do. My TitaniumBackup restores just fine(apps only). Ive ODIN'd back to JFD twice but still nada. Ill try starting from JI6 and see if it helps.

So I'm running ttabbal's latest kernel, 2.0, and just ran a quadrant. It gets 1564 as the score. Now, this isn't just from voodoo alone, he's done a few speed tweaked which will bump up the score. But it's snappy as hell.
"if you amplify everything, nothing is heard"
Just put this in my phone and its works fine I'm running axura 2.1 works fine but u will see a second boot up screen the benchmark test is not that high I got in the 2500 with the oclf inthe market download but can't do that one anymore it tells me I have one installed already but over all its smooth
Don't worry about benchmarks, they are easy to fool in a high level system like Android. Cyanogen managed to get something stupid like 10k out of Quadrant.
This setup isn't for being a benchmark queen. It's targeted at a couple things I deem important. Multitasking smoothness/performance, and a test of direct-to-ext4 install. The no-wipe voodoo kernel is really intended to be used as part of the whole, but like I said, it should work with any froyo. Note: NOT ECLAIR. If there is more demand for an eclair version, I'll consider updating my eclair ramdisk as well.
As for the market, couldn't say. It's NOT the rom/kernel though. The market is a finicky thing and sometimes just doesn't work. It's usually the server side or the app itself that has an issue though. There's also an update to Market for Froyo, it seems to be more stable. You should get it downloaded automatically after running for a while. To check, look at an app description, you should have a new tab "Related".
When I've had market problems, I fire up my Wife's G2 on a stock rom (not even root) and she does too, so it's not anything I, or anyone other than Google, can control.
Does anyone know whether the Dragon Kernel that works with any Froyo ROM available from the OP supports use of a BootAnimation.zip?
UPDATE: Thanks geoffcorey for the info!
Tried on Axura 2.1 with larger nand. Flashed, rebooted, converted with no issues and is running very well so far. Haven't been successful getting Voodoo to run before now.
Thanks to TW, ttabbal, Supercurio, et al.

So I can flash this kernel over my setup on Axura 2.1 and it'll move everything over? What are the dangers? If for some reason it didn't boot up is there a way to recover without Odin?

I did this very thing in my post #16 above yours. Go for it! Remove any other lag fixes you may have though. I had none installed so I didn't have to do that. PERFORM A NANDROID backup and optionally copy to a computer before flashing the kernel to be safe. Restoring the Nandroid backup won't restore the kernel though.
The dangers are minimal if you backup. Permanently bricking the phone is unlikely. You may soft brick but you probably won't. PLUG IN AND DON'T TURN OFF THE PHONE UNTIL THE "TW" LOGO DISAPPEARS! Around this time, you will hear a voice say voodoo has been activated.
I believe the conversion process may attempt to revert the changes it tried to make in the event of an unsuccessful conversion. If reversion is successful then you should again have access to CWM to flash back to any rom you have stored on your phone. Use nandroid to restore your data and your back to normal.

Most Complete/Stable Vogue Android Build

So I've just recently flashed my vogue with myns donut for a couple days and It was pretty good. The camera worked but no video and neither did the gps. I understand that for verizon you have to follow a specific procudure to get that to work so that makes sense. I'm just curious to what android roms they are using for their vougue. I'm looking for one that has the most working features. Let me know what it is and how you had it set up.
For my Fresh Froyo although remember android no is 100% stable but Fresh Froyo is very good.
If you know what you want my barebones build is known to be one of the fastest and most stable builds. With that though you need to get the apk's to what you want and add them in. It is meant to be as cut down to the minimum to be light and lithe on our devices.
Another way to get apps is to use the market, I have the most recent version of the market in my build. CM 6.1 is Froyo based so you have video and all the other froyo features.

I tested more than 10 ROM including the yours and I am sorry to tell you than ever before me to worked well even the last released CM 6.1, does not work properly with the kernel that is in my signature and is the one that works best with the USB sync and just by this already this ruled out your ROM, so I'm still saying Fresh Froyo for me is the more stable and clean ROM of froyo that I tested.

Well mine is assuming you want to use the .32 kernel. Which with Clemsyn's kernel works very well. Battery life sucks though since the changes haven't been committed to git yet. But with that kernel I have not had any data loss since it came out.

This is my situation too....as I posted above. I know how to install, but am unsure of exactly what you are recommending as to the Fresh Froyo files. Thanks again.
Well try to be brief to that understand... (my English is very bad).
They must go to the thread of Fresh Froyo and go to this page, there download the ROM latest although I recommend the penultimate that is in my signature the most recent gave me problems.
The ROM download whith the name system-froyo-us-unodex-XX-XX-XX (X are date) have to rename it to androidinstall.tgz and copy in the ANDBOOT folder then locate the kernel of their choice here, the most recent is 2.6.32 although I recommend 2.6.25 which is in my signature if need USB mass storage in 2.6.32 doesn't work.
For the rest follow the installation guide in NAND is here and everything should go well.
Not be as it is done for HARET but here also the Guide to install in haret. I believe with what I said is more than enough so installed android in their device.
Best regards.

It works in Ubuntu Linux. It does not work for Windows 7, at least that I could configure successfully.
I'm using SuperFroyo and the 2.6.32.9 Kernel and a few things I noticed to make it more stable: don't use a Task Killer and be sparing in your use of a cache cleaner. Seriously, a week of doing that has really helped things. Trust the Linux Kernel, it's not Windows. I also used Autostarts to prevent a few of the more eager apps from starting automatically post-boot, but that's optional.

I cannot as I do not have Clemsyn's kernel so I cannot commit his fixes for stability to git. As far as the git kernel goes it already has those fixes.
Also with fresh froyo or any AOSP build you will not have as much speed since it does not have all the Cyanogen Mod tweaks.
So it loses a lot of those tweaks but I can say 1 thing about cm6.1 and 7 so far, they are getting rather large themselves, I can look into cm7 for hero and find atleast 10 apks that just take up space or are only good once

Does seem contradictory as to not use a task killer, the task killer close applications that are open and if you don't use are accumulating and this put slow the phone, the APP autostarts manager if I heard but none that worked well in my Vogue, which do you use?

You don't need a task killer. The newer versions of Android will shut down apps that aren't being used if the resources are needed elsewhere. If you run a Advanced Task Killer or something similar, it will use system resources shutting down apps that then re-open themselves, which the task killer will again kill. It drains the battery and makes the OS unstable. Uninstall your task killer for a few days and see if it helps.
I use Autostarts because it fixed a problem--the music player started randomly. I also use it to prevent some apps from starting up but it is probably not necessary.

[Q] Honeycomb running very laggy

I flashed HC onto the Nook Color, from this thread http://forum.xda-developers.com/showthread.php?t=936995, and it seems to run very slowly, sometimes not registering my touches too well. Is it that way normally or should I flash back to Nookie Froyo? If so, how?
Thanks
Because the source of the rom is a modified SDK image, there were many work arounds that had to be made to the compiled code. As such, the rom can be very shaky, and really isn't suited to be a daily use ROM.
THis image is not representative of Honeycomb; once we get the source code, devs should be able to make a much more stable version and really make an amazing ROM.
Yeah that is normal. Honeycomb at this point is basically a demo. The only fully working non-stock ROM is Froyo.

Wow... so... You should probably READ a lot more before flashing anything, but I'll give you a few hints to get you going:
1) Make sure you understand what a "PBL", "SBL", "Kernel", and "Modem" are and how they are placed/installed in your phone.
2) Learn how to correctly and safely use ODIN (and/or Heimdall).
3) Learn about the various methods of recovery for "soft bricks", and if necessary for your hardware revision, possibly invest in a jig (also learn what a jig is)
4) There are 2 different types/branches of ROMs for the Captivate:
-- Samsung Branch
-- AOSP Branch
Within the "Samsung" types you have:
- i9000 ROMs (like JVP, JVR, JP8, etc)
- i897 ROMs (like JF6, KF1, etc)
Within the "AOSP" types you have:
- CM7
- MIUI
- Other AOSP-based ROMs
Which is "better" is relative. CM7 and MIUI have features that aren't present in the Samsung ROMs, and both offer a bit more customization than the Samsung ROMs. However, only the Samsung ROMs offer GPU accelerated video playback, and they tend to have significantly better battery life than the AOSP-type ROMs. Also the Samsung-type ROMs used to be much more stable than the AOSP branches, but recently, the tide may have turned in the other direction. Some of the low-level radio settings are also unavailable in any of the AOSP builds. And finally, some of the Samsung stock camera features are unavailable in CM7/MIUI.
It really all depends what you want... Do you want closer to stock "open source" Android? Or do you want Samsung's vision of what they think Android should be?
Also, the whole kernel/modem part is dependent on what branch of ROM you plan on running. When using a i9000-Samsung ROM, you pretty much have to use an i9000 kernel and modem. When using a i897-Samsung ROM, you pretty much have to use an i897 kernel and modem. The rules for CM7/MIUI are a bit more vague, but at the very least you'll need to use a CM7/MIUI (most AOSP-type kernels are interchangeable) compatible kernel.
The best advice is really to try them all out and see what you like the most. If you're currently on stock 2.1 (which it sounds like you are), at the very least you should upgrade to some variant of Gingerbread (2.3.4 preferably). You will definitely notice a big difference in terms of speed and functionality. From there, well, it's all really up to you...
OR alternatively, just start throwing stuff on your phone and see what happens. Just PLEASE don't come crying back in the Captivate General forum with a "OMG I bricked my phone!!! Plz help!!!" thread. Fair warning...
Just a suggestion, but become familiar with Odin one click. Make sure your captivate has 3 button recovery, and read, re- read, and read again the directions of every rom before you flash it. Always make a nandroid back up if possible, and read the threads.if you have questions, so did someone else and the answer is probably already out there .use search. Some People will rip your head off if you don't. as far as miui goes .....i was a flashaholic when I got phone. After switching to miui, It is very unlikely that I will ever leave. Best rom ever imho. And it updates every Friday so that satisfied the flashing urge. Usually it gets better with each release. The last couple have been a little rough though. Might want to spend the 8 bucks and have a download jig on standby. Can get it from mobiltech videos. Its worth it though

CM7 and MIUI have features that aren't present in the Samsung ROMs, and both offer a bit more customization than the Samsung ROMs. However, only the Samsung ROMs offer GPU accelerated video playback, and they tend to have significantly better battery life than the AOSP-type ROMs. Also the Samsung-type ROMs used to be much more stable than the AOSP branches, but recently, the tide may have turned in the other direction. Some of the low-level radio settings are also unavailable in any of the AOSP builds. And finally, some of the Samsung stock camera features are unavailable in CM7/MIUI.
It really all depends what you want... Do you want closer to stock "open source" Android? Or do you want Samsung's vision of what they think Android should be?
Also, the whole kernel/modem part is dependent on what branch of ROM you plan on running. When using a i9000-Samsung ROM, you pretty much have to use an i9000 kernel and modem. When using a i897-Samsung ROM, you pretty much have to use an i897 kernel and modem. The rules for CM7/MIUI are a bit more vague, but at the very least you'll need to use a CM7/MIUI (most AOSP-type kernels are interchangeable) compatible kernel.
The best advice is really to try them all out and see what you like the most. If you're currently on stock 2.1 (which it sounds like you are), at the very least you should upgrade to some variant of Gingerbread (2.3.4 preferably). You will definitely notice a big difference in terms of speed and functionality. From there, well, it's all really up to you...
OR alternatively, just start throwing stuff on your phone and see what happens. Just PLEASE don't come crying back in the Captivate General forum with a "OMG I bricked my phone!!! Plz help!!!" thread. Fair warning...

a very simple and easy way to start with...
2.1 is eclair..
2.2 froyo
2.3 gingerbread..
means 2.1 is oldest and 2.3 is latest in case of official roms..
so obviously new version will hav more features and faster in speed...
so now u can take baby step and install 2.2 ..and use it for few days..and get the feel of it..then again after sometime u can install 2.3...
or else u can directly jump to 2.3....which is gingerbread....u can install stock kf1 on ur phone..its leaked official gb...if u search a bit..u will get it..
then u can use it for a lil while and get the feel of gb stock rom..in the meanwhile u can read xda abt available custom roms..and then install any of them...
coz every memeber here in xda will suggest the custom rom they r using..coz they r lovin the rom then only they r using....like for me..since the time i started flashin..i always used APEX ROM..so i will say its the best....
but again thats just me..
so decision is always urs...

Since nobody seems to check the Q&A forum [Q] Kernel compiled in Ubuntu 12.04 fails

Since nobody seems to check the Q&A forum [Q] Kernel compiled in Ubuntu 12.04 fails
So i havent worked on a kernel in a while and decided id start workin on one again. Well I recently updated to 12.04 lts and no changes to my old source I just did a test compile and it wont boot. Same toolchain, source, ramdisk, etc.
Is there some sort of issue with compiling on 12.04?
Even redownloaded the source from my github and tried the toolchain recommended by samsung, stock tool chain, and 3 others and i still get nuthin. Just trying to compile a 2.2 kernel for the vibrant. No source i download works am i missing something?
does ANYONE have any ideas? I dont care who you are just something! I been at this for a freakin week and cant figure it out, ......i've changed nuthing but the OS and i really dont want to have to redo my entire setup because it is such a huge pain
Are you sure the kernel works? What is causing it to not boot?
I build ICS kernels just fine.
Check this and update tools for 12.04 http://source.android.com/source/initializing.html

100% sure it works, its the same source as my old nightly# 3 kernel which i can flash and works fine. Its a 2.2 kernel so thatd be the main diff there, and I've already done the setup of the build environment. I dont get past the vibrant logo so i have no idea what the problem is >.< its driving me nuts
i tried the linaro TC, 2 diff code sourcery, google toolchain even, and no luck
I even started a fresh kernel from scratch and added just the EXT4/voodoo stuff and my ramdisk and still nuthin
so i remade my voodoo ramdisk and that still doesnt work.
I'm out of ideas, I've quadruple checked to make sure all my tools and erthing are installed......idk what the issue is
Not a developer but wouldn't downgrading to an older Ubuntu fix the problem? Btw I loved your gingerbread kernels and I hope you can get back to the top again Aim for 400mb ram with 720p and you will achieve something high

Id rather not but it seems that might be the case -_- I gotta look into how well older versions of ubuntu suppport the BullDozer cores before i do i guess.....
also I only made GB kernels for the NS4g i think ? o .o Vibrant I had been workin on it but I like being able to have MSAA in my games and what felt like greater stability, so i scrapt the new projects in favor of specific features i use :3
Ecotox I really wish you or another dev could make an updated CM7.2 kernel with Voodoo Color, OC/UV, and performance tweaks since Glitch is outdated and probably won't be updated for CM7.2. I know most devs have gone to ICS kernels, but CM 7.2 is still snappier and better for gaming then ICS.

I've been gone working on a game project, so I really haven't been doing much android stuff in months. If I get some time I might but can't make promises. Don't take this the wrong way but I'm looking for some help if anyone has any ideas not requests or compliments on previous work (though both are appreciated)

Hey there! Try downgrading gcc and g++ to version 4.4. If that doesn't work you can always just set up a dev VM in xen or vmware instead of blowing away the whole box. Hope that helps.
