[Q] Installing cm 7 or unlock bootloader and install cm 10?

Sony ericsson xperia x8 11W43 e15i firmware version: 2.1 update 1 kernel version: 2.6.29 build number: 2.1.1.C.0.0.

I want to install cm 7 or better 10 on my phone. I know cm 10 requires that the bootloader is unlocked, which it is not.
It has turned out to be a very difficult task and I have not succeeded.

Another user on this forum has made a big effort to get cm on my phone. That is why I know how to root the phone and set usb debugging and allow other software sources.

I have got this software at hand
s1tool, gingerdx v0.31, X8_E15_2.1.1.C.0.0_generic.ftf, cwm.
Furthermore I have been using recoverx from google play.
Nothing worked. Gingerdx never starts, I have tried to let the phone boot for 20 minutes several times.

I also tried the paid wotanserver dot com option in order to get the phone's bootloader unlocked. That also failed, because when I ran the wontanserver software on a windows 7 hp computer, I could not login to wotanserver and execute the bootloader unlocking. Wotanserver could not provide further instructions, and I got a refund.

I am informed about the 11w36 issue, that is why I have not tried to unlock the bootloader using s1tool. If there if new information about how to unlock the bootloader I would very much like to get it?

If you know a working 10usd paid option to unlock the bootloader, please tell me?

I have also in parts read posts about testpoints to unlock the bootloader, but no post has come to a conclusion whether it can be done?

Failing can be related to me not installing correctly or there is some error about the phone.

Thank you for answering.

This is what I have done about ten times.

Set and marked usb debugging and other software sources.
Rooted the phone using s1tool.
Installed cwm using recoverx from google play, or a cwm file.
Flashing gingerdx from sd card using cwm.
Reboot.

Everytime the phone gets stuck in boot mode. Then I have to flash X8_E15_2.1.1.C.0.0_generic.ftf_FILES in order to get a working phone.

You ask me to do a factory reset after I have flashed the phone into working order again?

The part about wipe Dalvik cache I do not get. Is that something I do on android 2.1?

When I boot into cwm, which can take several tries, there is a wipe option, do you ask me to select that option before flashing ginger dx?

I get if recoverx worked like it should do, flashing the phone would be a small task.

On this forum in some posts there has been some efforts to testpoints unlock the xperia x8's bootloader. To my knowledge, they did not come to a conclusion.
