So you have a R800 that can't be unlocked officially i.e:

Bootloader unlock Status: No

What this means is that while we can get the device's bootloader unlocked(TP method), it will not enable fastboot access.
So we lack the ability to flash kernels, in .img formats...but why not just make a FTF packed kernel, which we can flash through flashmode?
I'm actually not sure to tell you the truth(*insert conspiracies*), but that was the solution this whole time...

Note: I have only made FTF versions of Turbo Kernel v3.1 by CosmicDan (R800x/R800a/i/at) I have vouch for the R800a to be working, others will need testing....(just have stock FTF ready to go)


STEP 1: BL Unlock Via Test Point method (Locked BL Only)

If your bootloader is currently LOCKED:
Read TP Guide by DragonClawsAreSharp...If you don't feel comfortable doing this...stop reading.

If you are comfortable with unlocking the bootloader then go ahead and do it.
Here is R800 TP location(quick google search): Here, and with red can use a paperclip and hold it to the (-) battery terminal to achieve the same results as the TP cable the guide shows.
In Flashtool (if you ever noticed):
S1_Loader_Root_773f - Version : R4A066 / Bootloader status : NOT_ROOTABLE (lies)
will now become:
S1_Loader_Root_773f,S1_Loader_test_Root_xxxx - Version : r4A069 / Bootloader status : ROOTED (huehue)

STEP 2: Prepare for Kernel

For GSM Only: Flash R800i_4.0.2.A.0.62_phoenixvendor.ftf with Flashtool. Let device fully boot to language selection page.

Read through Turbo Kernel (or what ever kernel.ftf you plan to use)
Grab a rom, look at the compatibility section on the kernel page.
Copy rom over to root directory of phone memory card.
Prepare your body?

STEP 3: Kernel Time + Rom

R800a/at/i Turbo Kernel 3.1 Download
R800x Turbo Kernel 3.1 Download

More Kernels!! Thanks denisfgn

Flash via Flashtool in flashmode.

Unplug and hold power button until 1 vibration....wait...wait...

Wait for the blue LED + vibration?, then press Volume Up. You should enter a sexy recovery...
Select: "Slot 1" > "TWRP Recovery" > "Wipe" > Wipe Cache, Dalvik Cache, System, then Factory Reset.
Go back to main page (hit back button), then select "Install", scroll down to the Rom you copied to the device, select and install it.
If you forgot rom: plug phone into computer, then in TWRP Select "Mount"> "Mount USB Storage" copy rom over to phone then install it

Reboot. Done.

This method should work for all Xperia 2011 devices that lack fastboot, but can be/are unlock via testpoint (anyone that can test let me know). Just need kernel to be in packed as a .ftf...

HAS THIS BEEN DONE BEFORE?? Maybe I can't search properly...

Do you think there's a chance for my WT19a 12w31 with "bootloader unlock allowed: no"?

Could you share the resulting .ftf? I tried to, but it fails everytime. I don't know, maybe I'm missing something or it only works with the mini pro sk17.
Iīve been trying with my girlfriends mini st15 (already unlocked bootloader via test point) and just canīt make it work.
Does someone have a jellybean ftf kernel for the ST15?? Thank you...
