[HD2 Android NAND Development] spookymo:
its all on the first page, but here is a rather short fail-safe version:

edit: if this your first non-wm-rom ever you need to make sure to have hspl 2.08 at least.

current radios can be found here:

http://xdaforums.com/showthread.php?t=611787

2.15.50.14 is the current version which seems to work well for most people.

if you need help with installing the radio ask google and only when this doesnt help ask here ;)

do not try to flash the rom if you are not certain that your radio supports it!

once you have flashed the radio you can start with the rom:

download the following 3 things:

rom:

File Server linkhttp://bit.ly/y9E1WL MD5 verified, OK

Note: Rename the file to zip file, server removes the .zip for some reason

or from torrent (way faster):

Torrent: [XDA] TBD_Stock_Sensation_XL_Gen3_EU_3.4.zip.torrent MD5 verified, OK

clk 1.5:

ext4 recovery (optional but advised):

- make a backup of your sd-card. titanium backup for apps/data and then just copy it to your harddrive somewhere.

- format your sd card in the correct way.

(one way:

google for gparted live - burn the gparted live CD - boot from cd, connect your sd-card to the pc in some way (sd-carrd-adapter, micro-sd usb adapter or whatever you got), select the sc card in the gparted tool (devsb usually) - kill the current partitions - create a fat32 partition with 1024MB free AFTER the fat32, create an ext4 partition of 1024MB after the fat 32. both of them primary partitions. make sure to create the fat32 first)

this is just onw way - google might provide many other ways to create an sd-card with a 1024 ext4 partition at the end.

- extract the downloaded clk1.5 and put the neoimg.nbh on your sd-card (fat32 partition - the one you see when you connect it to the pc) in "root" - so no special folder. just put in on there.

- put the other two zips on the sd card as well. (ext4 recovery and rom)

-put the sd card in the phone.

- power on phone while holding the volume-down key. let go of the volumd-down as soon as the screen turns grey - if you push it too long it will revert to the the colored stripes and you need to reboot again (by pressing the little red button or removing the battery)

- press power button in the menu to install clk.

- reboot the phone and keep holding the back button

- in the menu that comes up:

Select settings then repartition nand

since you are from italy i suppose you own an EU phone. in that case:

recovery = 7 MB

misc = 1 MB

boot = 5 MB

system =172 MB

cache =7 MB

selct them by pressing the call-button, select +-1/10 by volume keys - apply by call button - press back button to get back to the menu.

once you have all the correct values choose COMMIT - check the values again - select YES if its correct.

during the reboot press home-button to get into cwm menu.

- install zip from sd

- choose the ext4 recovery - confirm

- once done get into the power menu and power off the phone (i dont remember whether your need to avigate to the power menu with the back-button or not. you should be able to figure that out.)

- power the phone back on while holding home-button.

you should now be in the ext4 recovery with battery status on the top right and a fancy looking background.

- install zip from sd

- choose the rom

- confirm

- dont remember if it reboots automatically or if you need to power it off (with the power menu)

dont press anything during next boot. boot will take quite a while. leave it alone for 1-2 minutes once the first lock-ring-screen comes up.

do the phone setup.

leave it alone for 10 minutes.

connect it to the pc with your usb - get your titanium backup folder (or whatever you used) back on - restore your stuff - done.

(if this is your first android rom you obviously dont have a backup - just make sure to save your photos/music and stuff from the SD before you format it)

hope this was clear enough

so long,

spooky

PS: most of this is more or less copied from danstas instruction - but since that is on the first post of this thread and you still asked for a step-by-step i just assumed you read it and it had steps missing for you. so i inserted everything that dan might have assumed self-explaining for people with a little experience.
