Brickbug Aftermath: Speeding up the Galaxy S2 i9100, S2 AT&T i777, S2 Epic 4G Touch d710 and Note n7000

UPDATE: CM 12.1 kernels are now available!!! (for CM 12.1-supported platforms only: i9100 and i777.) new kernels are rom-independent: they are no longer tailored to specific official CM builds (they might work with other roms too) and their names no longer reference a specific CM build.

UPDATE: this project now supports all roms and kernels!
if you are not running CyanogenMod M snapshots, please see this post.

this project restores TRIM capability to CyanogenMod kernels for the Galaxy S2 family of 4210-based devices: i9100, i777, d710 and n7000. TRIM is needed to avoid "aging" of the state of the eMMC, the internal flash storage, that eventually slows the device to a crawl. TRIM functionality is built into android 4.3 and later. however, due to historical and safety concerns, TRIM capability was removed from the CM kernels for these devices (and from most if not all other AOSP-based kernels).

STOP!!! DRAGONS AHEAD!!!

in theory there could be risk of hard-bricking your device forever.

1) READ THIS POST IN FULL.
2) answer this poll (view results).
3) discuss your n7000 experience below in this thread.


Downloads

for the supported devices, you will find IsoRec-compatible CyanogenMod-based kernels here. (old kernels without IsoRec support can be found here. yet older retired kernels without FPBug fix are still available here.) note that for some supported devices, no releases or M snapshots are currently being produced. for those devices i can produce kernels based on known 'stable' nightlies if users ask.

Can this kernel be used on Slimkat and Slimkat based ROMs ?
AFAIK they are based on CM kernels !?

Hi, could you perhaps make a kernel with these implementations but based on CM11/Omni? Any of the latest nightlies are "stable".

OHkay.. then i guess you should proceed and create a kernel.. its time we test them.. but will it improve speed by a huge margin or it is just a placebo?

It will vary from user to user, but if you have high I/O lags then yes, there will be a big improvement.
