GINGERBREAD Hacked/Compiled Kernels: Share your opinion/experiences/feedback

I was just curious: how is your experience with the various hacked kernels available like, for instance :CF-Root 3.0] JP*,JS*,JQ3,JV1/K - su+bb+2e/CWM - rfs+ext4 by Chainfire
Hacked Lagfix/Ext4 Samsung Galaxy S Gingerbread - JVB by supercurio
[KERNEL][GPL][SECURITY] FuguMod 3.0 (gingerbread JVB) voodoosndv7 by nikademus
DamianGTO Ultimate Ginger Kernel by DamianGto
SpeedMod Gingerbread by Hardcore
Talon Kernel by ytt3r / existz
​Do you know another one?
Tested a couple of them, pretty much satisfied with the responsiveness and battery performance, no bugs or issues, BUT UNLIKE many hacked/compiled kernel users I am always on RFS and have all tweaks disabled....(edit: not anymore, testing some tweaks right now)
In the begining running Gingerbread the sgs was having some weird battery performances, but after removing a bunch of bloatware and freezing another bunch (using Titanium app), like "software update" for instance , battery performance is stable.
Some feedback about this and the other kernels would be nice, specially from users like me, that wont do the "file convertion thing" (always on RFS).

Well first i try Supercurio, Gingerbread-GT-I9000-stock-from-sources-kernel+hackskernel, and work so well. Then i try Supercurio again Gingerbread-GT-I9000-dev-kernel+hacks, and it´s a complete kernel is really a good Kernel, estable, and work so fine, and not draw the battery.

Actually i have Darkys v10.0RC5b2 rom and try DamianGTO_Ginger_Beta_6__340HZ, no good it´s unstable and with the ram don´t work good.
Now I have Ficeto Kernel, Dark Core 2.0 and really work so good with the ram and with batery, it´s very stable and it´s a complete Kernel whit lagfix and ext4.
Now I want try Dark Core 2.1 and probably the last Hardcore´s Kernel, speedmod-kernel-k15c-test5-o2-09q3-500hz, perhaps now without reboot problem.

Hmmm....I dont think your probs are kernel related but more MOD ROM related....

You missed the Hardcore's SpeedMod kernel!

From the beginning JVK and now JVB both deodexed by Ramad with CFRoot is a winning team for me.No ext-4 stuffs,or as a test...killing time...,and just happy like that.Flashing mods and themes,enjoying his CWM application,can't thank enough Chainfire for accompanying us in our wish to use this 2.3 «release».
Only one sudden battery drain as far for me and it was a google process.Maybe related to maps,read that somewhere...

MY SGS New XWJVB Problems...
1. my screen going off when im still working...or playing game...or calling with loudspeaker (check this) (when not touch)
2. always on my touch buttons lights (menu= back keys)
3. didn't play some games (restart phone and stucking) but can play that games on my older froyo firmware...
I'm using XWJVB (old i use XXJVK) with CWM3 EXT4 File Sys...... please....tell me this gingerbread releases are still beta or final releases?

I'm using CF-Root 3.1 and it works but haven't that much to compare with because I'm new in this stuff and haven't tested any other kernel.
I'm using Simple Honey 3.1 (JVB) right now with CF-Root 3.1 + EXT4 converted and wonder if I'm able to change kernel without wipe the phone? If I don't need to wipe then I may study the difference between those kernels
Great puting all up to date kernels in one list tho, that makes it easier for me and others who are curious about them.

Fugu Mod working absolutely perfect here..

I haven't had any problems on all the kernels.
It is just a matter of taste i think.
Some have other features (focus areas) then others, but in general they are all stable. Even the released developers version of supercurio.
So it seems that they all know what they are doing.
Personally i am using now the damiangto kernel for the more memory, just because i have SPD Shell 3D running and it consumes at lot of memory.

Here's my very, very executive executive summary:
- I rooted using CF-root 3.1 (not 3.0, filename was "CF-Root-XW_XEE_JVB-v3.1-CWM3RFS.tar").
I used this only to gain root and to flash CWM3-dependent patches, so I didn't get to fool much around with it. But from my light usage, I definitely didn't notice any problems.
- I've been running pretty much all JVK/JVB-revisions of supercurio's kernel so far (for the ext4 lagfix) and I can't really complain about anything. The added audio-drivers are definitely a bonus. Can't live without them now. I haven't had any issues with performance nor stability.
- Fugumod.
I'm absolutely alien to this kernel/mod and really have no experience with it. Not tried it once. That said, people has said earlier in the JVA/JVB/JVK-thread that when they rooted using Fugumod, they had issues connecting their phones to Kies afterwards. And they said a reflash of stock firmware and then using CF-Root instead solved their problems.
Unless you have some very specific reasons to go this route, it seems this is the only one with consistently confirmed problems so far and might be worth avoiding. Maybe the problems have been identified and fixed though. Not absolutely sure here.
- DamianGTO.
Absolutely alien to this one as well, but haven't seen any posts about specific issues either.

Hmmm havn't tried darkcoreGB yet...

And since you didnt have any problems with all the kernels, let me guess:
You are always on RFS and you dont use any mod rom right?

EDIT: Just noticed: Damian's XDA account is currently disabled? And somebody else edited his first post?
What's going on?
....

I was on Darky RC3 with DarkCore 2 and wasa super smooth and fast.
Then I decided to try MIUI RC6 ... run it from Friday to Sunday when I gave up:
1. camera not working
2. touch keys are iffy, sometimes they work, other times they don't
3. My 3G network kept dripping all the time
4. try to flash differnet modem broke IMEI and had to reinstall the whole ROM
5. when alarm sounds, i could not stop it unless i lock and unlock the screen
6. there is no support, for every issue I had the answer was: it's in the FAQ
So I am back on Darky 10RC5.3 and much more happier; faster, smoother, camer works, 3G is fine, i can flash any modem I want and above all the support team is fantastic.

Battery life
What about battery life? I test speedmod for 3 days and I find less battery autonomy that 2.2.1.
For a medium usage after a day it's over!!!!
Does anyone have this trouble???

Yeah Damian is no longer at xda. He is still developing tho at his own forum. Using his beta7 with no issues do far except a hot reboot after I wiped cache

[Q] Stock rom with latest patches?

Hey guys I'm pretty new to android roms etc etc I have a 512 mb gen 2 european blade that much i found out but i wanted to know whether there was a complete stockish rom with the latest kernel patches? I am running GSF now and it is fast and stuff but i would really like it to go faster with the latest kernels as it was updated quite some time back so i imagine it wont have the latest patches... any ROM without any cm7 mods and all just plain and simple stripped and modded stock with latest kernel mods like gpu axi uv etc ?

Try Swedish Snow : http://android.modaco.com/topic/350875-romgen2-swedish-snow-rls5-android-235/
Send from my awsome ZTE Blade!

And best ROM in terms of performance?

U know the answer cm with tons of performance boosts and options

to be honest if you want your phone to go faster i would go with cyanogen mod 7 latest kang + wbaws kernel with GPU overclock

So the stock based ROMS arent the ones with the best performance..?okay and by latest kang which should i try?(i really dont want to overclock and things like that as it may damage the phone no?)

Err.. Cyanogen?
In my experience, cyanogen is one of the heaviest and slowest roms I've encountered, although that might just be me . It's filled with cool stuff and options though.
So far I've been hugely impressed with Elite Blade Rom:
[ http://forum.xda-developers.com/showthread.php?t=1310050 ]
It also has a stock looking ui, except for a sexy lock screen. It's very fast, and battery lasts f o r e v e r. Which is very important to me atleast.
Overclocking doesn't damage your phone, because it only lets you overclock to about 800mhz, and if it doesn't like that clock, it just crashes and goes to normal. Around 730mhz always worked for me, and battery life seems not to be affected.
Stock roms are like buying a new laptop, filled with user friendliness and sponsored apps. In other words; Mighty damn slow. So custom ones are definitely the way to go.
One down, nine to go!

By stock Roms i meant stock based modded roms but i agree thats what i thought was bad about cyanogen that it was real slow when i tried it once before i dont thats why understand how the KANGS will make a difference plus i want stock similar roms as there are no bugs not even minor ones for example in elite blade in landscape mode in the status bar the peeking android looks weirdly stretched and stuff the small things..are perfect in GSF.. if the KANGS can work faster then im willing to try that but preferably i want to know if there's a way to add the latest kernel patches or the latest kernel to GSF..?
Thanks for the replies guys
(Swedish Snow was nice but for some reason GSF still feels faster )

hmm ok i will help you out a bit after trying a lot of different roms available for the blade including ones not available on these forums since they are only Chinese based (im not chinese i just like to try out there roms).
Overclocking will not damage your phone mate because if you overclock your phone to a limit which is not supported by your phone it will simply reboot and put back the normal CPU settings for your phone to work in a proper manner (Do not tick set CPU settings in boot).
GPU overclocking is nothing to worry about because the GPU will overclock when you overclock the CPU (3D games experience on the ZTE Blade has improved)
As for other saying they find cyanogen mod 7 slow i do not know what version they flashed but i prefer to use CM7 Kangs developed by BurgerZ & Kernel developed by wbaw (both extremely talented devs).
The reason others may find CM7 slow is because they use ADW Launcher (free) by default but burgerz uses stock gingerbread launcher.
if you dont want to use CM7 my second fav rom for performance would be Swedish Snow
@ruckus92
i tried the rom when it was updated last, it was not bad neither good as the libs it uses need updating nowadays.

CyanogenMod is pretty bloated, but some kangs are not as bloated.
I find that Burstlam's kangs are pretty light and fast. I guess he must have gotten used to developing for Chinese blades (they only have 256 mb of ram)
You can find his latest build here.
I have tried the stock-based roms but didn't notice any major difference between them and Burstlam's rom.
And like Kannibalism said, ADW Launcher free is slow as heck. I suggest you switch to ADW Launcher EX, or a different launcher the next time you try a cyanogenmod rom.

Can't this guy flash wbaw's flashable kernel over GSF? It should work right?
Sent from my Blade using XDA app

After updating the libs and trying burstlam and burgerZ 's Kangs with wbaw's kernel i am really satisfied even though i lost the stock feel.. Thanks a lot guys
@karthiknr is that really possible? Could you confirm? I'm not very experienced with flashing so i dont want to do something wrong..Thanks

Yes do make a backup

i think he should be able to flash the kernel with GSF but its best to take a backup first mate

Okay guys problem..Its stuck at the screen before the boot animation.. What do i do now? How do i restore the backup that i just made..? Am i in some sort of trouble?

nope no trouble mate just restore your backup
follow these steps:
1) take out the battery to turn off the phone
2) power on the phone holding the power button + volume down button (keep holding do not let go of these two buttons till cwm boots)
3) Clockwork recovery will boot up
4) select backup & restore
5) select the backup you want to use
6) wait for it to restore your data could take a few mins
thats all mate

Ah i was scared to death hehe thanks my phone's working fine now stable fast and smooth And what about squadzone's unofficial cm7.2 rc5.6 is that the latest kang?

[Roms] CM 7.2 Mod and X1 Elite with market. .32 kernels.

So, this is just the result of my messing around with these roms and tweaking where I see fit. They are both .32 franco kernel based and I flashed and tested both with CWM 5.0.2.6.
CyanogenMod Tweaked
First one is CyanogenMod 7.2 and owes everything to the amazing work by Ezet.
Original thread is here: http://forum.xda-developers.com/showthread.php?t=1527745 and tweaks are here: http://forum.xda-developers.com/showthread.php?t=1227269 Thanks to Ezet and Knzo
I have tweaked it by building a new kernel and editing the build.prop as well as adding other tweaks from elite rom by terramino. It also has bravia engine built in and a few apps removed. Seems smooth and a little sharper than before. Battery may end up being a little better too. Will have to see.

What about a Custom Kernel?
Just for my experimentation, I have made a custom kernel. It has my smartass V2 mods, various other governer mods, SimpleIO enabled and default and a couple of other small tweaks. Just flash it and see what you think. If you want the old one back, just reinstall the rom. It seems very smooth and battery efficient to me.

Superb Work Dude. Can You Please Upload This For U8800Pro And Add Some Screenshots Please.

Will add screenshots sometime, but I don't have a pro to test the rom with if I make a rom. Also which rom did you want me to mod for the pro?

Says SD card available - can't access any of my music or files.
Any clues, I've probably just missed something??

Got it sorted, did another set of wipes and it seems to be all good.
Looks like an excellent ROM - nice and smooth.
I've just come back from the .35 kernel which was too buggy for me and and loving this.

great stuff, glad you got it sorted.

Do you gonna update this when CM new releases/updates comes, or this is just one time project?
Also you said you did lot of modifications, but did you tested original ezet rom with yours and did you see any effect? Or something that tells you that your rom is somehow better? I'm just asking because of i want to try but if there is really no way of telling the difference than i will pass it to the next time

I will keep it up to date as Ezet updates his rom. I ran Ezet's rom for ages by my standards but I was just taken by the smoothness, battery life and camera of Mossterra's elite rom x1. I have tried to combine the best of both.
I have tested all the mods thus far except battery life as I only installed it two days ago and it all seems positive, faster and smoother. I put it up so if people thought it was ok, they could use it and feed back.
All I can say is give it a try and if you like it, keep it, if not, Ezet's CM 7.2 rom is fantastic still.
All the changes will be overwritten if you install ezet's rom over this one or vice versa. They are compatible without a full wipe, just wipe cache, dalvic cache and fix permissions after installing.

My last tiny little bug - I have disabled haptic feedback (in both Sound & Cyanogen settings), but I still get vibration when clicking any of the 4 menu buttons (back, menu, home, search).
Thoughts??

Disable in x5 settings maybe? im not sure, I normally have the opposite problem of trying to get haptic feedback on.

Which Apps have you removed from CM7?? - having some issues with the default email client - meaning I can't find it, and restoring backups isn't working for me.

heh... sorry, I removed it as I don't use it. Flashable zip now in first post with email.

Well, looks like I cant get init tweaks to stick so this rom is just bravia engine and some build.prop mods until I can figure out why.

OK, well new kernel is up, will be releasing a new rom with this kernel and some more tweaks and superuser updates as soon as I can get it to upload.

Still using and loving this rom - looking forward to the upgrade

Ok, New rom is up. New Kernel, updated superuser, set permissions for bravia engine correctly. Seems to work very well and smoothly for me.

[Kernel] 308 Kernel for ICS

Here is something I have been working on and thought I would share.
It is a 3.08 kernel based on DZOs source and modified with some governer settings the way I like them, a bit of tuning of the voltages and cpu freqs, and a lot of cherry picks from different sources.
Sources:
Mine:
https://github.com/PaulMilbank/kernel_huawei.git
Build off the master branch with the u8800_defconfig if you want to compile yourself.
Where I borrowed from:
https://github.com/Blefish/android_kernel_huawei_u8800: Quite a few cherry picks from the ICS_Chocolate source.
https://github.com/virtuous/htc7x30-3.0.git: Mostly KGSL fixes from here.
https://github.com/ezeteze/u8800-kernel: Gave me an idea about how much to undervolt by.
https://github.com/dzo/kernel_huawei: Pulled some old fixes from the .35 ICS source
https://github.com/TomGiordano/kernel_huawei: Pulled some changes from the .35 ICS Source
Mostly these have been cherry picks that I integrated into my kernel and some tuning by me.
Also thanks to fjsferreira for his guide on compiling DZO source: http://forum.xda-developers.com/showthread.php?t=1577876
Everything that worked on DZOs kernel should work here and it should also fix a few annoying bugs.
Notes:
First Kernel:
The battery life is largely improved. I easily get 24 hours use and could probably get up to 2 days if I turned wifi off and turned mobile data off when I was not using it.
I have not seen the random text corruption on this kernel. I did see it a few times on the original aurora kernel.
It seems at least as smooth as the original Aurora kernel, maybe a bit smoother.
It should leak slightly less memory and handle kernel events better.
It is not magic though, you may still have the odd reboot and not everything is perfect. It should be at least as good as the original and hopefully a lot better.
Not so much distortion over back speaker.
Added SIO cpu scheduler.
07/10/2012 update kernel#22:
Swap and Zram enabled, need to test.
1.8ghz is back
368mhz minimum clock.
13/10/2012 update kernel #54
Some CAF and Huawei pro wifi code for testing.
Changed readahead (may need to wipe cache, dalvic cache for this, seems to cause some apps to force close without those wipes.)
Couple more KGSL tweaks
Couple of Bluetooth tweaks.
14/10/2012 update kernel #55
Revert most wifi changes, I am still getting wifi sticking on, will likely have another revert here too.
Reduce readahead some more, please wipe cache, dalvic cache and fix permissions when flashing after this change.
fix a line of code I forgot to add
Revert a franco change.
Boost lowmwmory killer values to hold a bit more ram free and kill appps/background processes a little earlier.
SuperStock Kernel
Test kernel for those with issues. Just latest DZO config, latest DZO source fresh from his github, no CAF or Franco changes
Undervolt from 308 Kernel
368mhz minimum, might need to set this to 245 to match DZO kernel
lowmemorykiller updated
swap and zram enabled.
Hopefully this should show where issues are occurring in my other kernel.
If you get a reboot, do the following from a terminal or over adb:
Code:
su
cat /dev/block/mmcblk0p7 > /sdcard/crash.txt
Then post the crash file (if it has anything in it) here.
Get it Here:
07/10/2012 Kernel #22: http://www.mediafire.com/?o5niwi1jb73j2jn

SuperStock Kernel: http://www.mediafire.com/?67o0y9kc2956fy1
Works in Aurora and Miui, I tried it in AOKP, but it did not boot so something went wrong there, not sure what yet.
Will update here and on GitHub too as I make more changes.

Is it possible to provide only the Kernel update?

Can we undervolt even more?

Is this just on my kernel or the original Aurora too? have you tried tap to focus or holding the button down until the square goes green to show it is focussed? Should not be blurry if it is focussed correctly.

Anykernel updater posted.

can you try to compile JB source from code Aurora with this kernel. it might get quite stable now.

Thanks Paul your kernel + init.d tweaks = super silky smooth ui great work mate

Glad it is helping people. What init.d tweaks did you use?
Also I won't be compiling roms from source. I don't have the hardware to do it. Kernels are about my limit.

I get random touches in the right edge of the screen with this kernel. Synaptics digitizer.

Not sure about this, have not changed anything with the synaptics driver. If it worked in DZOs kernel, it should work here.

so if u want to use on aurore i only need to download the file on the first page and your kernel is already there?

Can I use this kernel on Elora ROM?

I was waiting for any kernel!!
Already testing and tearing screen problem gone, WiFi is super fast! You have done really great job!

[Q] Custom Kernel and updates

Heya, everybody.
I'd like to know if you guys could recommend a good kernel for undervolting and overclocking the Nexus 7. (I'm only looking into very mild overclocking, I don't want worse battery life)
But here's the main thing: I'm wondering about how you'd best go about updating your tablet after flashing a custom kernel. Will I be able to take OTA updates? Am I forced to flash new ROMs every update?
I'd just like the most simple way of updating my OS while being able to overclock and undervolt my Nexus 7. (OTA updates would be the most simple, right? If possible ofc)
I've got a Nexus 7 32GB. Android 4.2.1, IC 3568A-ME370T, Model ME370T, Build JOP40D

there aren't many kernels so quick search through android/original sections 1st pages you can find information about everything you need. i would suggest m-kernel or omega most stable (on my device) and with features you seek, although OC is kinda pointless IMHO if you are not going to benchmark it and given how scores/real world perfomance show well...it's pointless
i think you can't easily just update rom and keep kernel, but it's not much work, download newer version of the rom flash it, flash kernel, boot and resume... 5mins tops.

Okay, I'll have a look at them. Thanks.

Well, even if I'm only getting a 5% increase in performance or battery life I still consider it worth it. It's a rather simple upgrade that will last for years (I plan on taking good care of my device )

Wait, so you can update Kernel and ROM separately?
Am I correct in assuming that most ROMs (including stock) come with a Kernel that will replace whatever Kernel I have?

I am using trinity kernel alpha 4 version along with cm 10.1 ROM. Can over clock to 1.7 GHz with this kernel. Downloaded trinity tool box also. You can under clock, over clock and set voltages along with some kernel tweaks. Has worked flawlessly so far. I also downloaded and installed cyan delta app. It will flash the delta file of each nightly you want and also flash kernel all in one shot. (Cyan Delta will only work with CyanogenMod ROMs.)

I'll probably use Franco if possible, cuz amazing battery life. I noticed that my Nexus 7 only lasts like 5hours when gaming with it(stock clocks). That's not good enough for me! :S
If it doesn't work I'll probably go for Omega or M-Kernel. (or AOKP stock kernel)
I'll probably go for Paranoid Android 3.0 with the Franco kernel. I've read that they're compatible.
Updating to newer versions might be a bit of a pain, but the cool functions are probably worth it :3

You don't need to update every time a new version of a ROM or Kernel comes out, you know. If it's setup and working perfectly, the best thing to do would be to enjoy your tablet.

OTA updates do a lot of validation checks before they begin; in fact, they perform a checksum on every file targeted for a patch update.
It is quite common (not always, but common) for the kernel or ramdisk to be modified during an OTA update - so this means a high likelihood that an OTA update will not succeed on a device with a custom kernel.
There are lots of ways to do what you want, though; two basic strategies would be:
- From a backup, restore only the (stock) boot partition. Apply the OTA, and then restore a backup of your OC kernel/boot partition.
- Using Titanium Backup (or Carbon), back up your apps & data. Restore a pure stock backup, and take the OTA update on that. Make a Nandroid Backup of this. Flash the replacement kernel & a root kit. Boot and restore your apps. (This method is more labor intensive).
Note the frequent mention of full (nandroid) backups in the above. Backups are a good thing to have; make them early and often.
Anyway, there you go - two methods for the price of zero.

I prefer PA3.0 & Motley Kernel

I use PA3.0 with Motley Kernel and it works like a champ. There are stretches where I get 2-3 days of battery life (but I am paranoid and have everything disabled when I don't use it, and brightness down to ~15%). The link you provided though is a good resource.

Well don't expect major improvement in battery life while gaming, maybe if you down clock CPU for less demanding games, if you run demanding 3d games like Horn you will drain battery fast. Kernels change from version to version, performance and battery wise, so try different versions from same Dev. When it comes to games the way tegra 3 is designed you will not see much of benefit if any from oc cpu. Just look at the latest m36 kernel, your n7 will basically become dual core device with immeasurable performance loss. All I want to say don't expect wonders. If you are after battery life I would suggest you to look into other less bloated ROMs, like code fire, dirtybox, rasbean jelly. Paranoid is great in some aspects but I found less popular roms are easier on the battery, but not by a large margin.

I would have to agree. You do not have to update your rom with every nightly or your kernel with every version. If your tab is working fine, use it for what you got it for. Sorta like Murphy's law. If it ain't broke, don't fix it. (Read the changelogs)

Yea, I won't be reflashing things unless there's new features that I really want.

Motley is apparently one of the "worst" kernels when it comes to optimization and battery life. The best thing about it is probably the features, but I don't really need any of them, so I probably won't be using that one

Yea, that seems to be the case from what I've read. But flashing the stock kernel would make it work fine, right?

This seems like it has a possibility of going wrong. I think I'll go with the second method.

This method is actually not that "labor intensive". As long as you've got Ti Backup Pro it's very easy to do this, you just gotta wait a while things backup/restore.

Yea, I realize now that battery life when gaming probably won't change much.
Battery life is very important to me, but if it comes at the expense of features then the difference has to be noticeable.
How has your experience been? (compare the ROMs you've used)
