[Captivate Android Development] existz:
I keep seeing the same questions asked over and over, most of these have already been answered in the first 10 pages or so but they keep getting asked, so again im going to post the basics that you need to know about this kernel (Some of this is taken from Hardcores FAQ...READ IT!)

[Q] What do all the tweaks in CWM mean? And which tweaks should I use?

[A] The speed tweaks in CWM is taking from Hardcores Startup Speed Tweaks here, http://xdaforums.com/showthread.php?t=813309. You should use the first 4 tweaks, as the optional tweaks are only support for TUN and CIFS, if you dont know what they do then you do not need them.

[Q] After I flashed this kernel my screen does not rotate correctly..

[A] You have flashed the wrong version, there are 2 versions of this kernel, one for the Captivate and one for the i9000, the correct one will say i897 in the file name, make sure its there

[Q] After flashing this kernel, I have static using bluetooth or during phone calls

[A] Chances are your using a Captivate modem, this is an i9000 kernel tweaked to work on the Captivate, so you need to use an i9000 modem, theres quite a few to choose from (JK3, JK4, JL2, JL3..etc) Theres a link in my sig, under the modem I use, where you can download

[Q] Im using JPY or another i9000 rom, do I need to flash the Captivate version or the i9000 version?

[A] You need to flash the Captivate version. This kernel is an i9000 kernel but the Captivate version is reoriented so it works correctly on the Captivate, the i9000 version is for the actual i9000

[Q] Does this kernel include the Wifi Battery Drain Fix?

[A] NO, this is not kernel based, if the Rom you are using did not include it, you will need to download it (Link is in my sig, JPA WiFi)

[Q] Do I need to disable lagfix coming from K12K to K12L?

[A] No, you do not need to disable lagfix when switching to a newer version

[Q] I am currently using a Lagfix. Do I need to remove the lagfix before changing kernels?

[A] If you are using a loop lagfix like RyanZA's One Click Lagfix (OCLF), you *must* un-lagfix first. But if you are upgrading from another Universal Lagfix Kernel or Voodoo, you don't need to remove the lagfix. However, it is always safest to remove the lagfix before changing kernels.

[Q] Which lagfix do you recommend?

[A] I recommend EXT4 All lagfix, with the SAFER ext4 mount option. Other lagfixes have a high risk of data loss if the phone crashes or is suddenly powered off or rebooted

[Q] Whats the difference in the "warm" and "cold" versions?

[A] If you screen is to yellow, flash the cold version, it makes it more blue to even it out. If your screen is to blue, flash the warm version, it makes it more yellow to even it out.

[Q] Whats the difference between the 250HZ version and the 500HZ version?

[A] HZ is an internal timer value used by the Android/Linux kernel. It affects the timer granularity of some kernel functions. The higher the HZ, the smoother the User Interface should be, up to a certain point - too high a HZ value will make CPU-bound tasks slower. However, the differences are very minor.

[Q] When I try to go into recovery I now have 3e and says ..

[A] Follow my guide here, takes about 2sec and your good to go.. http://xdaforums.com/showthread.php?t=909213
