There are 2 versions you can try with XXJPU: - K10J (JPM-based + XXJPU modules) - K11-XXJPU (XXJPU stock kernel + SpeedMod initramfs features)
Both versions also work for older firmwares as far as I can tell.
For K10J: - Some people have problems with the USB connection
For K11-XXJPU, CWM, lagfixes and tweaks will be available, but some SpeedMod features will be missing: - No CIFS - No HZ changes or other kernel optimizations - No sharpness/color tweaks (hello ugly text!) - No BLN
But K11-XXJPU should be the most compatible with the XXJPU firmware.
Switching back to stock plain kernel: - I added stock xxjpu kernel to the downloads for people who want to switch back and test. Make sure you disable any lagfixes before switching back.
