The file I downloaded was from the
Froyo Kernels thread and was called "slayher_7x1200LV_v1.6.zip" - to install, do the following:
- Download the zip file and place it anywhere on your SD Card
- Choose the "Install ROM from SD Card" option in ROM Manager
- Navigate to where you saved the zip file and select it
- You'll be prompted to "Wipe Data / Cache" and "Backup ROM", now there's no need to wipe when installing a kernel, however I HIGHLY recommend making a backup just in case the kernel cause you to boot loop
- You'll reboot into Recovery, the backup will be made, then the kernel will install and your phone will reboot
Once it reboots, you should now have the kernel installed. To confirm, goto Settings => About Phone => Kernel Version. It should say something along the lines of 2.6.32.9_slayher
