I have started this thread based on zdzihu's suggestion...
This thread is intended for Developers ONLY...
A method of booting custom kernels (using kexec) has been developed. Thanks Bin4ry, zdzihu, jerpelea, MrHassell, blagus, and all other devs who are working hard to make this stable. (i am sorry if i missed any names)
hope the devs can use this thread to discuss on custom kernel dev....
please keep this thread clean for the devs to discuss the kernel development aspects...
for general discussions please use the following thread:
http://forum.xda-developers.com/showthread.php?t=1018391
i will also keep updating this regularly with the information like relevant posts; features, limitations & links to custom kernels currently available...
*** [IMP]: before flashing custom update.zips read this: how to find the version/type of recovery on ur current ROM ***

Additional Info:
the following files are required in the /system/kernel/ folder:
splboot.ko (some devs move this file to /system/lib/modules/splboot.ko)
miniloader
boot.img (this is the actual custom kernel)
for booting the OS using custom kernel some modifications are required to the /system/bin/chargemon file
also some modified/updated modules (e.g. wifi.ko) are provided for compatibility with the custom kernel
Bootloader Bypass files:
There seems to be some issues face by some users, where in using a different version of miniloader helped them sort out the issues. So I will provide all those versions.
Flashable update.zip via recovery, contains miniloader & splboot.ko:
bootloader_bypass_files_v1.zip [slightly older miniloader] {came with older FreeXperiaKernels}
bootloader_bypass_files_v2.zip [older miniloader] (testing only) {came with FreeKernel by zdzihu}
bootloader_bypass_files_v3.zip [older miniloader] (testing only) {came with Flashtool v0.2.9.1}
bootloader_bypass_files_v4.zip [newest miniloader] {comes with newer FreeXperiaKernels (from CM7 J022 K011 onwards)} (recommended)
[IMP] for v4 miniloader: u need to be on the baseband from the baseband package provided in CM7 J022 for the v4 miniloader to work properly... even if u already have baseband 2.0.52 please reflash using the baseband package provided in CM7 J022... even if u are on a different ROM u will need to use the baseband from the above package to get custom kernel to work properly

One question for bypass-method developers: is it necessary to have stock SE's ROM for better chances of succeeding in porting splboot/miniloader to X8?

---

2.1update1 - base anyone can restore with SEUS, demonstrated work from this point, with the FreeX10, FreeXperia, Wolfbreak, rendeiro2005 and others without many problems. It might be a case of, which has the least issues, what are they and how do we eliminate them.
The most common baseband with development is 52. FreeXperia - CM7 GingerBread - entirely developed for 52 - there are two groups.
Original Baseband series: 48-49-50-51-52 (52 = last of first generation)
Current Baseband series: 53-54-55-56-57-58 (59 - not released)
Baseband is a multiplexer. The core C files are - vendor/qcom-proprietary-qsd8k/data/qmi/qmuxd/../src/qmi_qmux.c and is compiled for ARM with* vendor/qcom-proprietary-qsd8k/data/qmi/qmuxd/../platform/qmi_platform_qmux_io.c and the core interface to the Linux kernel - vendor/qcom-proprietary-qsd8k/data/qmi/qmuxd/../platform/linux_qmi_qmux_if_server.c requires several SO - (ELF binaries) - be present, compiled and available to the kernel and the linker - /system/bin/linker
liblog.so
libdiag.so
libc.so
libstdc++.so
libm.so
Everything working - /data/radio/qmux_connect_socket - will bind to an address path and make possible, one radio with one input signal to many data-output-lines and many input lines. Herein the core networking is established, with WiFi and Bluetooth become linked, with the famous exploits for NULL pointer dereference vulnerability which exist in Linux kernels < .30 - Which is no coincidence, why many Kernels are below this release version.

how can we flash the .img file?

A little more info please, wich kernel are you talking about? Tripnraver's, zdzihu's..?
If it's tripnraver's kernel you try to flash, you should just flash the zip-package you downloaded

---

i am talking about FreeXperia Kernel-002 by j.
This kernel is only available on .img file

---

You should place all your kernel files in /system/kernel/ and you must make some changes to chargemon (/system/bin/chargemon). I have no idea what changes you should exactly make..

---

hmmm...
i will re-upload the boot.img zips as update.zips flashable via recovery...
also for general discussions please use the following thread: http://forum.xda-developers.com/showthread.php?t=1018391
in the above thread i have already posted the changes which need to be made to the /system/bin/chargemon file to boot using custom kernels

---

system/bin/chargemon
system/bin/charger
system/lib/modules/wifi.ko
and Kernel folder needs to be copied out from ROMs to get custom Kernel.

i would not recommend copying the file /system/bin/chargemon as is (because of the different recoveries available & variations that each dev/each version of flashtool introduces) rather only search for the custom kernel booting part and add that to the chargemon file if it isnt there already...
also no need to copy the whole /system/kernel/ folder... u just need the boot.img for that specific custom kernel... (though here i assume that u already have miniloader & splboot.ko in /system/kernel/)
and yes individual rewritten modules (like wifi.ko) have to be copied too... it would be great if the devs can post update.zips which contain the hotfixes/addons (including custom kernel, modified modules, etc) so that the kernel and related files can be used on other roms too, instead of downloading the whole rom...

---

i would like to confirm that FreeXperia Kernel-002 by jerpelea (from CM7.0.0 J015 k002) is working well on Achotjan's V010

Has anyone tested one of the available kernels on FreeX10 Beta 4 ?

---

[Q] Is it also possible for x10?
Hi, I just found this:
http://forum.xda-developers.com/showthread.php?t=889503
So i wanted to ask wether it is possible to implement it in the custom Kernels of X10.
