These kernels are provided as-is without warranty. I'm not responsible for any problem you can encounter with your phone or if your cat suddenly dies.
Although, don't expect support even if I will eventually help since I love cats.

Note : These kernels are only compatible with CyanogenMod and MIUI roms !

Do you want to discuss on this kernel, get the fresh news on development, or become a kernel tester ?

Join the IRC channel from your web browser
here ! No registration needed
Make sure the channel is "#glitchkernel" and you're set.

For those who already have an IRC client,
here is the server :
port : 6667
Channel : #glitchkernel
Overview :
- Up to 1.7GHz CPU OC with added bus/GPU OC (Thanks to morfic for the great base of work)
- Undervolting (using third party apps)
- Voodoo Sound & Voodoo Color (Thanks Supercurio & renaudallard)
- FPS uncap (Screen running 68Hz instead of 60Hz, from 56 to 66 FPS max) from JPX source
- Various tweaks for more smoothness and reliability
- LED notifications using Neldar's BLN
The frequency/voltage & informative UV settings table is as follow for V13 kernel :

Note that these UV settings will be unstable on many devices. It's only informative.

1700 MHz - [email protected] 243 MHz - 1.500v / -> Most phones will fail here. -25 to -50mV may help to stabilize. Much stabler as unique frequency for benchmarks.
1600 MHz - [email protected] 229 MHz - 1.500V / -> That's high and many devices will fail on this frequency. Find working UV for you if any.
1500 MHz - [email protected] 250 MHz - 1.500V / -25mV
1440 MHz - [email protected] 240 MHz - 1.475V / -50mV
1400 MHz - [email protected] 233 MHz - 1.450V / -50mV
1300 MHz - [email protected] 217 MHz - 1.400V / -50mV
1200 MHz - [email protected] 200 MHz - 1.350V / -50mV
1000 MHz - [email protected] 200 MHz - 1.250V / -50mV - If you have stability issues, try to let this one by default.
800 MHz - [email protected] 200 MHz - 1.200V / -75mV
400 MHz - [email protected] 200 MHz - 1.050V / -100mV
200 MHz - [email protected] 200 MHz - 0.950V / -150mV
100 MHz - [email protected] 100 MHz - 0.950V / -200mV - (can be very different between two devices)

GPU frequency is linked to bus speed

More volts is not always equal to more stability. Try to add more UV (less volts) if the frequency you're trying to achieve is unstable.
Considering all phones will respond differently to OC/UV, to tweak the values to suit your device will be required.

By default, no overclock/undervolt is applied. You'll need to use one of the tools below to adjust the frequencies and voltages.

Because I got tired of answering these same things 100's of times.

1) Where can I find the latest beta?
They are always in the OP. They are also in my signature, and the root of the FTP.

2) Where is the root of the FTP you ask?
Good question! It’s in the OP as well.

3) How do I install this? / I'm having problems installing
Reboot into recovery
Install zip from SDcard
Choose zip from SDcard
Navigate to the zip you downloaded.

4)What is Leakage (LL,ML,HL) and what one should i use?
Easy explanation: start with HL. If it allows you to OC how much you want, stay there. If not, move down until you get what you want.
For people who want more: Well, we made different leakages because koflem couldn’t OC, and he felt left out, so he started compiling on his own, which gave Tk-Glitch the idea to make three different versions. They have to do with the differences in different phones. Take for example different phones run better with different OC/UV. The leakages are the same way. They adjust the int voltages, which is something not configureable (yet) in userspace, so we have to configure them that way when we build. That way both the voltages that you are used to (the ones controllable via voltage control) are tailored to your device, as is the int voltages (the ones only we can do). Most people have no idea, but there are dozens of variables that we play with to make so that all of you can OC and UV as much as possible with as much stability as possible. Some aren't device specific, some are. We are trying to make the best experience possible for a wide range in chip quality, therefore we make different leakages, as well as making the kernel configurable via voltage control. From a stability/performance standpoint, and by extension standpoint, there is only one leakage right for your device. Different leakages aren't better in some ways for you and worse in others, there is only one good one for your device. Sorry if that didn't make sense, I tried to make it as informative as possible without it being overwhelming.

5) Does this work with Gingerbread bootloaders?

6) What ROM does this kernel work on?
For sure: CM7. Other CM7 based ROM’s may work, but I can’t offer you much support. If it works on CM7, that’s my goal. This WILL NOT work on Samsung based ROM’s, and I won’t port it. If you still don’t know what ROM this will work on, then you should read a lot more.

7) How do I enable BLN?
Download either BLN here: Or Blinky here:

8) How do I overclock?
Xan’s Voltage Control App here: . READ THIS GUIDE FIRST: If you break something while Overclocking, I won’t provide much support. Overclocking is awesome, but very variable across devices. We try and make a stable experience for everyone, but it is not guaranteed. If it breaks, I didn’t do it. If it makes your phone fly, I did it.

9) Can I be a beta tester?
Probably not. Unless you do something to make me like you a lot (cough strictlyrude27 cough), then you can’t have betas. The reason being they are unstable usually, and I already have a big enough team that I can get the information I need.

10) Why does my screen look ugly? / How do I change the screen color?
Go grab voodoo control from the market here: , then play with the sliders until you like what you see. If you get really stumped, here are some values that people tend to like. They are from zacharais.maladroit.
Screen RGB multipliers:
- Red: 321*
- Green: 321*
- Blue: 429*

Screen v1 gamma hack:
- use Alt. settings
- or if you prefer others - use: "Reset to 2.3.3 defaults", "Punchy settings" (punchy could lead to a great screen while locking the screen and having "screen off" animation disabled)

1)Color Profiles: Voodoo Profile V1
2) Screen v1 gamma hack :
- 50 red
- 53 green
- 44 blue

3) RGB multipliers:
Red ="2300875360"
Green ="2300875360"
Blue ="2709919680"

11) The backlights on my soft keys stay on all the time. Why is that?
Honestly, because I haven’t spent the time to “fix” it. They aren’t that bright, so people can stand it for a little while. I didn’t intentionally make it that way, it happened when we switched back to BLN instead of LED notifications. We made that switch because I like Blinky, and I get to pick until Tk-Glitch is back, or I am convinced otherwise.

12) I’m getting bootloops, why?
Well, the most common issue is that you have mismatched ROM’s and kernel’s. You need the latest ROM for your device, and the V12B3 kernel for your device. For where to find that, see above. The next is various scripts and “fixes” that you flash after/before the kernel. Reflash the nightly for your ROM, then the kernel. Let it boot. If it works and didn’t with the various other zips you may use, then don’t use those zips.

First Rule of Cyanogenmod... I'm allergic to ETAs so I try to stay away from them if at all possible. Causes all kinds of nasty problems they do....

14) How do I use the 90_callvolume script?
Download it here:
neh4pres wrote these instructions, if clarification is needed just ask.
There are many ways to apply this patch. But for these instructions i will be using root explorer because it has all the utilities needed.
After downloading, use root explorer to extract 90call_vol from the .zip. this will place 90call_vol in the extracted folder of your sd card. Long press and copy that file and paste it in the /etc/init.d folder. Once it pastes long press the file and open with text editor.
In call boost.. only change the final number in the line you want to adjust and keep that number between 0 and 3
Mic gain only change the final number in the line you want to adjust and keep that number between 0-31
Save changes when exiting and the editor will append the original file with a .BAK . You can use 90call_vol.bak to revert back one save. If you change multiple times and want to go to stock you can use the 90call_vol in /sdcard/extracted.

15) Is the GPU overclocked?
Yes. Can you control it? No. That code hasn't ever worked, and we don't really expect it to. The GPU is so overclocked at 1.5 Ghz that if it went any higher the memory would get corrupted and really bad things happen.

27/05/2011 - V10A Do not use with CM7 builds older than 23/05 (as well as the 28/05 or newer build) or MIUI -> you'll get no service !

- Now fully compatible with latest CM7 Nightly builds
- Back to 2010.09 toolchain -> slower & less stable but needed to make a working kernel for latest builds
- Upstream sync (bigger radio partition, headset stuff..)
- Int voltage changes to get some stability back on all overclocked frequencies

- OC code bugs and inconsistencies introduced in V7B now fixed (it was here to prevent sleep of death issue, now fixed)
- Some fixes and enhancement for compatibility with Xan's Voltage Control app
- Various tweaks for MOAR SPEED
- Black magic

Known issues :
- The reboot recovery command seems broken for some reason on recent builds. Probably rom related.
- Some users still get freeze issue on boot. If you have this issue, please use the "no-optimization" kernel for you device from this post :

03/06/2011 - V10B To use with newest builds only (equal or newer than 28/05) !

- Upstream sync (FM radio, new Voodoo Sound implementation, etc...)
- Back to 4.4.3 toolchain - needed for new RIL
- Big cleanup - rewrite from scratch
- Many fixes
- New tweaks for speed on 4.4.3 toolchain
- New tweaks for stability on 4.4.3 toolchain
- Black magic

17/06/2011 - V10C (Updated) To use with newest builds, #28+ for i9000 or equivalent

- Upstream sync (cpuidle, updated drivers (wifi etc.), Recovery 4.0.0.x, etc...) (updated as of today 17/06)
- More debug stuff disabled
- Dock audio support (experimental)
- Added DIDLE (Deep Idle) support (removed, buggy)
- New voltage tweaks for added stability on some devices
16/05/2011 - V9A

- Merged with the now dead V8C update because of new added features
- Upstream sync : Calculate battery percentage as percent of max capacity reported when battery full, new wifi driver, etc.
- New PMEM settings for more available RAM (now 331MB)
- 1.54GHz step added with some gentle settings for now.
- New step by step frequency switch when scaling down (part of the Galaxy S II port from Bilboa1) - more stability on highest frequencies
- Corrections and further tweaking on smartass governor + some fixes from Netarchy (Nexus S). 400MHz lock when screen is on removed (not needed anymore -> more power saving)
- Higher cache for faster SDcard read speed
- New sleep settings : Effective lock to 400MHz max when screen is off -> fix long wake up/hiccups when playing music or similar use. Be careful with your UV settings on 200 and 400MHz steps to avoid sleep of death problems ! These were not used on previous versions of my kernel (locked to 100 MHz when screen off and locked to 400MHz when screen on with a buggy gap in smartass governor forcing generally 600+ MHz)
- 600 MHz step removed (it was generating instabilities on some phones when jumping to 800 or down to 400 when using UV)
- Some voltage tweaks for added stability on some devices (as always)
- Cleanups on unused/no more needed stuff
- Little surprise, thanks to Morfic

- Updated to V9A² to fix SOD and some performance issues

21/05/2011 - V9B

- Upstream sync (CWM recovery, better screen colors (kills voodoo color for now and looks awful on my 0516 build, but should be good on latest), GPIO fixes, samsung modemctl...) + small changes on my side for official CyanogenMod repository compatibility
- Voodoo Sound updated to V9 / cleaned voodoo color stuff until it works again
- New cleaner bootlogo based on the one in first post, preferred by most users
- Some additional compilation flags from Netarchy and Zacharias.maladroit (better overall performances + NEON)
- Screen refresh frequency bumped to 72Hz (68Hz effective). It'll uncap FPS to 66 again but seems stabler than before on framerate (the divide/2 behavior happens less)
- Added screenstate scaling script from as a test (with my kernel's smartass default settings). It should give better sleep power consumption as well as better power efficiency on screen off tasks like music playing etc. by switching to conservative governor.
If you want more information, discuss on this or contribute to enhance it, please come here :
- Adding some stuff from Zacharias.madadroit :
- Higher battery charging temperature
- Scheduler tweaks
Alternative version now available (V9B-VC) using old AMOLED panel color/gamma settings and with Voodoo Color V2 added back.

24/05/2011 - V9C TO USE WITH CM7 Nightly build #12 OR HIGHER ONLY

(Updated to fix "no service" issue, but still sucks.. unstable on #12 build, very stable on others but no service)

- Upstream sync (PMEM disabled (gives 339MB RAM now), new RIL, headset fixes...)
- Divider changes for MUCH better stability on 1.2GHz at the cost of a slight decrease on performances
- New branch with Voodoo Color display driver and "old" color settings named "VC"
- Fix for Vibrant no service problem - hopefully
- Small changes on smartass governor for better scalability (reverts some old settings not needed anymore with the screenstate script)
- Glitch logo now in update script too for nanu_x2 to be amazed when installing my kernel

24/05/2011 - V9D TO USE WITH CM7 Nightly build #11 OR LOWER (for i9000, or cappy/vibrant equivalent) AND MIUI ONLY

First "D" revision.. Sound like duty. It's basically a fix of a fix done to make the V9C features available for "stable builds" (considering the i9000 #12 isn't)

- Obviously all the V9C changelog
- Using old RIL to be compatible with builds before #12 for I9000 (--> WON'T WORK with #12 for i9000 or equivalent !)
- Replaced 1.54GHz step by 1.6GHz (1.54GHz step was somewhat useless, too close to 1.5Ghz, and slower overall because of the lower bus speed)

- I can't build Vibrant ATM, the CM7 build system is broken on this device or I'm doing something wrong but I wasn't able to fix it. Any help is appreciated. I'm sorry for Vibrant users I'm screwed.
07/05/2011 - V8A - To use with 05062011 or newer CM7 build (useable on MIUI RC8 but you'll lose camera - MIUI needs an update)

- Upstream sync (camera fixes etc.)
- More stability fixes
- Cleanups on OC code (found that 1.2 and 1.3GHz were very unstable compared to earlier releases)
- More work on Vibrant/Captivate. The kernels are now available to download but are untested - for now. Feel free to try and report any problem or if all runs well. If I have enough positive reviews, these kernels will be released in their respective device sections.

11/05/2011 - V8B

Upstream sync only :
- USB switch suspend
- TV out stuff
- Fascinate specifics
- Revert "Got back to previous samsung_modemctl" for 05112011 CM7 build

02/05/2011 - V7A - To use with 05012011 or newer CM7 build and MIUI RC8+ only

- Resurrect Voodoo Color killed by 2.3.4 merge.
- New step for 1.5GHz on top of 1.44GHz (now 9 steps total versus 8 before)
- Forcing 400MHz max when sleeping for added battery life (default = 800). Couldn't detect any side effect.
- New tweaked Smartass governor now default (800MHz min when screen on). Please report your experience
- It seems the smartass governor is not working by default, it will revert to performance >< Please force it to get it to work -> Ok found the problem, I'll update in a min

- Now updated to V7A-2 to fix the governor bug

03/05/2011 - V7B - To use with 05012011 or newer CM7 build and MIUI RC8+ only

- Resurrect Voodoo Color killed by 2.3.4 merge - Again - fully working now
- Fixed sleep of death issue when unplugged
- Switched to LZO compression for better overall speed and reduced boot time
- Tweaked smartass governor more for - hopefully - better battery life and a bit more responsivity
- New voltage and frequency table rewrite as a bonus with now 11 frequencies total
- Stability fixes on 1.5GHz step -> please test and report
- Reverted FPS uncap - at least for now - for two main reasons : more stability on high GPU freqs (1.4GHz and more), and to prevent FPS limit at max/2 (33 when unlocked to 66), limiting overall performances in heavy scenes. I think there's a lack of buffering somewhere.. It will give higher scores on some benchmarks, and lower on others. A better battery life can indeed be expected too.
- Upstream sync

05/05/2011 - V7C - To use with 05032011 or newer CM7 build and MIUI RC8+ only

- Upstream sync (better battery life, reboot recovery, etc.)
- A general stability fix missing from V7 branch added back
- Tiny tweaks on the voltage table
- Big bugfix on the V7 branch (redone from scratch, cleaner)
- Switched to 2011.03 toolchain
- Added some optimization flags, "-mfloat-abi=hard" being one of them (up to 40% performance gains in specific cases)
- Small improvements here and there

22/04/2011 - V6pre - preview/work in progress of upcoming V6A update *test* :

- Reverted PMEM settings to new CM7 default (317MB - same as V5A)
- Reverted some stability fixes that weren't that stable on some devices, or even prevented some to boot
- New voltage table for a more linear increase, improving stability at default settings
- Switched to Deadline scheduler by default as it appears more stable
- Back to 2010.09 toolchain for speed and efficiency
- Synchronized with last update from SGS CM7 team

Better to use CM7 04212011 update with this kernel and newer.

22/04/2011 - V6pre - update 1 :

- Battery polling bumped to 15 sec (was 1 before), it should help battery to an extent (thanks to Zach for the idea)
- Some internal voltage tweaking to hopefully be more UV friendly
- Bumped USER_HZ for more smoothness
- Another -rare- bootloop fix

22/04/2011 - V6pre - update 2 :

- Added some tweaks from V5A for testing
- Resolved a bug generating fake voltage reading
- Resolved a bug on 400MHz step generating instabilities
- Slight changes to the voltage table
- Fixed a typo
- Trying some toolchain switch - again-

23/04/2011 - V6pre - update 3 :

- Corrected Led Notifications - Now it should work properly again !
- Various bugfixes and typo corrections
- Toolchain change once again
- Added new Interactive governor with aggressive settings for even more speed. You need to change it by app (pimp my cpu/cyanogen settings), it's still on conservative by default.
(thanks Zach for your suggestion)

25/04/2011 - V6pre - update 4

- Cleanups on Led notifications to resolve a bug (buttons stopped working randomly for some users)
- More typo corrections
- Voodoo Sound V8
- Various bugfixes on CPU load and schedulers
- CONFIG_CC_OPTIMIZE_FOR_SIZE disabled for speed
- Lower latency on GPU states switch for stabler performances
- Added a stability fix for voltage change latency when frequency is changing. It should give more stability with high undervolt or big voltage differences between two steps - Please test and report ! (Thanks Zach for pointing that to me)
- Two versions for testing purposes : V6pre-u4 is compiled using GCC 4.5.1 toolchain, and V6pre-u4(alt) is compiled using GCC 4.4.3 one. If you get instabilities on the first one, try the other and vice versa. Please report your findings on that because it was the first stability differences source between my kernel revisions. For information, V6pre-u2 was compiled with 4.4.3, and u3 with 4.5.1.

27/04/2011 - V6pre - update 5 >> 6

- Name changed from "TkGlitch" to "Glitch"
- Cleanups on buttons (Kangsterizer)
- Lower latency on GPU states switch for stabler performances in 3D and/or at high GPU frequency - corrected, thanks to Kangsterizer
- Added a stability fix when frequency changes for cpufreq governors
- Tweaked Interactive and Conservative governors for testing
- New Frequency table : 1.5GHz is now the max selectable frequency, and 800MHz and 400MHz steps are now replaced by a unique 600MHz one.
- Changed initramfs source to remove the annoying "E:no misc partition" error in the recovery

- Now bumped to update 6 to fix an issue with the conservative governor.

27/04/2011 - V6pre - update 7

- New Frequency table : 1.44GHz removed, 800 and 400MHz steps are back.
- Battery polling bumped from 15 to 30 seconds
- GPU power latency bumped from 10 to 60 ms

28/04/2011 - V6A - To use with 04282011 or newer CM7 build only

- New sensors drivers added
- Normalized 1.5GHz bus speed (GPU will now run @ 250MHz versus 247MHz before. It can affect your stability !)
- Int voltage lowered for 1.5GHz step because it did have a bad effect on lower frequencies stability
- GPU power latency back to default - but fixed (100ms)

29/04/2011 - V6B - To use with 04282011 or newer CM7 build only

- New initramfs source to fix compass and update CWM recovery
- 1.5GHz replaced by 1.48GHz for stability
- New voltage table as requested by many users (+25mv on 1200 to 1400MHz steps)
- New interactive governor for better scaling and battery life
- New tweaked smartass governor for testing (pretty bad on CPU benchmarks for some reason, please test how it feels in real world use)
- New ondemand governor from Zacharias.maladroit sources for testing

02/05/2011 - V6C - To use with 05012011 or newer CM7 build only

- Small update to merge with 2.3.4 source, no new feature.

02/05/2011 - V6C² - To use with 05012011 or newer CM7 build only

- Update to repair Voodoo Sound conflicts from 2.3.4 merge.
- Back to 1.44GHz max to prepare 1.5GHz return

19/04/2011 - V5A - Initial release
21/04/2011 - V5B :

- GPU overclock on 1.3 GHz added (217MHz / +8.5% from default)
- New PMEM settings for more available RAM compared to V5A (now 328MB)
- Stability fixes for all frequencies, needing globally less volts. Results may vary depending on the device
- Switched to Conservative governor by default (still switchable by app). It can feel less responsive coming from idle but more battery saving, and plays better with high frequencies.
- New voltage table. Default settings should be stabler for most devices.
- Switched to 4.4.3 toolchain for added stability on some sensitive devices

Captivate and Vibrant support will come later. It will need more time than expected.
21/04/2011 - V5C : Small update to fix a bootloop issue on some devices.

So maybe I just can't read , but does this have LED notifications, or did they get taken out when they were taken out of CM?

This kernel has them.

I won't be here much, but it's good to have a thread in there. It'll clean the i9000 thread a bit and will help users to find the kernel for their own device.
Thanks for the help sixstringsg

Hi guys, just wondering if anyone is having issues losing signal after flashing a different kernel with the latest release of CM7?
