Hi,

(To make it short, follow the red sentence to format your phone to avoid roms problem.)

I hex-edited RomUpdateUtility.exe so it runs task 29 right after flashing ruu_signed.nbh
Task 29 formats your phone memory (=binfs). It prevents weird error appearance when you flash new Roms.
But you stile need something to flash, it may be a radio, a splashscreen nbh or a blank nbh file (shadrack repack provide a tiny blank nbh).

Usually you don't need anything more than the file provided in the packs. so:
Just unzip and run task29.exe .
Eventually, you may replace ruu_signed.nbh with the radio/splashscreen of your choice.
When update status reach 99%, press vol down button, and keep it pressed until the phone reboot to the three color bootloader.
After the phone reset itself, your old rom will be gone, so it can't boot to winmo: binfs has been formated, your phone memory is clean.
if you fail to press vol down key and your phone get stuck on the white screen, just remove your battery, then try again: press power, and keep vol down pressed immediatly next, until the phone get to RVB bootloader.
When your phone is back to RVB bootloader screen, use the leocustomruu.exe provided with your favorite rom package to flash a new rom, or flash it from memory card using standard procedure.

No radio needed, smaller, faster.

To do:
remove the "reset" command from task29.exe, to stay into boot loader screen. Then, one should flash the new rom immediatly using their cook's flash utility.

So with this tool you can only flash the Radio? Then we have to use the other RUU_Custom.exe to flash the ROM?

exactly.
this is because flash utility needs a nbh file to write to the phone before sending task 29. as task 29 removes roms but not radio, and radio are quicker to flash, i choose this way.

am gonna try it too..
so we can replace the *.nbh radio with one we want every time and then flash it to the device..So a task 29 will format the memory and then we can flash as normaly the rom..

Great...thanks!!

great tool, but with mtty task 29 it takes a couple of secs to do this on a winxp machine. :)
i guess it would be more handy for vista/win7 users.

if someone could provide me with a blank, but valid nbh, then help me to repack all this stuff into a single exe, it should be a great step ahead.

That is exactly what came to my mind when I saw this. Right now my (And I belive most ppl.s) option is to either start up my net book (which has XP) for regular MTTY or go trough the headache of installing drivers for Win7.
Also another advantage to even MTTY under XP (if I know this right) is that we don't have to enter commands in the consul (so again time and effort saved).

If I get this right, then with this we don't need unsigned driver install on Win 7. Just to re-flash a radio of our choice and task 29 is done too? If this is so, then its great. Radio flash is really fast.
If this does work well then I would definitely recommend a sticky.

extract splash nb from official rom and repackage into nbh

i don't think you can make a totally blank nbh that would be accepted by the spl

    someone please tell me I can do a task 29 of some sort with no usb port, my micro usb is whacked and after changing roms a few times starting to become a little bit dodgy now :( please.

    if you flash a stock rom from sdcard, a task29 is performed automatically.
    but if you flash stock rom from sdcard, hspl will overwritten with stock spl.
    you need to reinstall hspl after installing stock rom from sdcard.

    @all:

    in the meantime, another RUU from barin (Advanced ROM Update Utility) will do task automatically after flashing a custom rom.
    you can also perform only task 29 with advanced ruu.
