[Q] Missing a step in flashing a custom rom on SE X10i - XPERIA X10 Q&A, Help & Troubleshooting

I own a SE Xperia X10i since it got released. Current versions of software in my phone are:
Model: X10i
Android: 2.3.3
Baseband: 2.1.71
Kernel: 2.6.29-00054-g5f01537 / [email protected] #1
Build: 3.0.1.G.0.7.5
Files and programs I have and use:
- Flashtool 2.9.1
- ulBlDoom.zip (for unlocked bootloader, obtained via forumthread of ROM named above)
- x10_gb_DooMKernel-v06-FS_wifi.zip (for unlocked bootloader)
- Speed&Hotfix004.zip
I wanted to flash a the Wolfs TW Gingerbread V7b6 custom ROM, but I had troubles getting the WiFi module to work. Here is what I did:
00) Copied all relevant zipfiles on the sdcard of my phone
01) Used Flashtool 2.9.1 to downgrade kernel with aZuZu loader.sin (supplied with flashtool)
02) Root (using flashtool Root button)
03) Used Flashtool 2.9.1 to upgrade kernel with aZuZu loader.sin (supplied with flashtool)
04) Used flashtool to install xRec
05) Rebooted phone to update Superuser and Busybox to latest version available on market
06) Rebooted in xRec and made a backup of the current rom
07) xRec: Factory Reset (full wipe), wipe Cache, wipe Dalvik as said in Wolfs TW GB thread
08) xRec: Install custom zip (ulBlDoom.zip)
09) xRec: Install custom zip (x10_gb_DooMKernel-v06-FS_wifi.zip)
10) xRec: Install custom zip (Speed&Hotfix004.zip)
10) Reboot phone
At this point the phone reboots and starts loading the new custom ROM. It fully starts and I can see that it actually is the new ROM. All functions seem to work (didn't test much though), except WiFi. Whenever I try to enable wifi from the menu it says "fault", right after pushing the softbutton.
I read all kinds of threads here on the forum, but I am too inexperienced to figure out what is wrong. All the information I find overwhelmes me and confuses me more and more.
Anyone here who can tell me what I missed or did wrong?

First of all man, there is flashtool ver. 7 and u using 2.9? Now u just click root and this is the end.
U should do it again, it will help for sure.
So repair phone in pc companion, reboot, check usb debbuging in settings, turn on newest flashtool, plug in turned on phone to pc, click root (wait a while, phone restarts) do not unplug, click instal xrecovery and this is first part.
If battery is low charge to 100%, copy all files to sd card, reboot in xrecovery, install rom and reboot, i think its better to reboot any time u flash sometnig, not all together. So reboot do not do anything skip everything wait a 5 min and reboot in xrec again then install wifi fix and reboot, not so sure about this Speed&Hotfix004.zip i cant remember Ive installed them, but for now try just rom and wifi fix and let me know will it work for u

Flashtool version 8 even! Don't know how i got to 2.9. Perhaps found it somewhere in the Demonlord kernel thread. The full folder name is "FlashTool_0.2.9.1-GBready_root_xRec".
I am going to try what you said, do the rooting and unlocking part, and then install the ROM.
On the previous attempts the rooting etc. went fine though. Got exactly the same results as suggested by the various how-to's explaining the procedure.
