Help with restoring phone to stock ROM.

I have to send away my phone for repair (USB port is dying) and i was hoping to restore everything to stock just to make sure there are no problems when they take a look at it.
I'm running 'Duttys Leo Multi-Lang V1.1' ROM but i installed this way back in January and to be honest i can't even remember how i went about doing it in the first place.
If anybody could tell me where to start i'd be really grateful.

download official stock ROM from your carrier site, or HTC site, and install it by clicking on .exe file
Will that remove the HSPL too ?

If you flash it via sd card. Right click on the exe stock rom file downloaded and select Extract here. Then copy to .nbh file to the root of your sd card. Ensure it is named leoimg.nbh and then flash from the card.
you can use HSPL to change it to 1.42.0000 SPL. there is an option there

Only if using HSPL2. As he installed the rom in January, HSPL2 was not yet out, so I'm assuming he used HSPL1
The SPL is indeed 1.42.0000, im just downloading a ROM now and i'll report back in a second
I had HSPL on my phone and used HSPL2 to remove it - works fine
Ok so i copied the .nbh to the SD Card, renamed it and restarted the phone while holding down the volume button but it just took me to the Bootloader screen.
Do i have to do anything specific to get it to install ?

Did you format the sd-card in FAT32?
It should ask you to press power button or something to flash if everything is right

When the phone boots into bootloader it should identify the leoimg file on the sd card and allow you the option to flash by pressing the power button. Did you copy the file to the root of the storage card, ie not to any sud-folder? If so then it could be that you may need to try another sd card as not all cards work with this. The 2gb cards are said to be best.
You can also try to just run the .exe normally from the pc to flash the rom and then use hspl2 to change your spl back as suggested by EddyOS.
Yeah, I didn't think it wouldn't work - just put my stock 1.66 ROM back on and then changed the SPL back using HSPL2 - job a goodun!!
Anyone wanna buy an HD2?
Thanks for the advice guys, i'm off to work now but i'll have a look at it when i get home.

you have to put custom ruu together with the .nbh file in the root directory of the card

Not true , only the .nbh file
Flashing Via MicroSD Card

2. Download your prefered Rom from the LEO Rom Develpoment Page and unzip/unrar it to your PC
3. Goto the Roms Folder and rename the .nbh file to LEOIMG.nbh
4. Copy the LEOIMG.nbh file to the root of your MicroSD Card
5. Plug the MicroSD Card into the phone
6. Reset the device while pressing the volume down button to enter the BootLoader screen, you will first see a tri-color screen with the phone and SPL Information at the top
7. Follow the On Screen instructions to start the update

Boot Screen Help.. Setting it back [ SG ]

Friends,
After flashing my HSPL and my ROMS so many times, I have suddenly gone blank.
If I need to flash my phone back to it's original state, and if I do not have my original ROM, what do I do?
Currently it's booting up with a picture of an Android and a Bird ( I forgot what I flashed to get that! )
I purchased this phone in Singapore.
Any assistance will be much appreciated!

[Q] Hard reset?

I'm looking to put android on my HD2 but I got a simple question.
If I install a NAND Android on my phone and I don't like it or encounter some problems can I get windows back with a hard reset or does that option get lost when I put Android on?
I got the tip to "You simply put the stock rom you want on your SD card, rename it to leoimg.nbh and then go into bootloader by holding Volume down while powering on."
I have tried to find info about this, can anyone point me in the direction where there is a guide/tutorial on how to do this it it would be very appreciated.
Thanks for your help!
No, a hard reset won't do the trick, you will need to reflash a winmo rom to get it back, as installing a NAND rom (even magldr) removes winmo.
You can find info here
Flashing Via MicroSD Card
NOTE (PLEASE READ): If you flash a Stock Rom via microSD Card then it will overwrite your HardSPL with a stock SPL included in the nbh file. This does not apply to custom roms as they do not include an SPL. BE CAREFUL!!
1. Make sure your microSD is Formatted to fat32 (you dont have to delete all files but it is safer if you do)
2. Download your prefered Rom from the LEO Rom Develpoment Page and unzip/unrar it to your PC
3. Goto the Roms Folder and rename the ********.nbh file to LEOIMG.nbh
4. Copy the LEOIMG.nbh file to the root of your MicroSD Card
5. Plug the MicroSD Card into the phone
6. Reset the device while pressing the volume down button to enter the BootLoader screen, you will first see a tri-color screen with the phone and SPL Information at the top

This has been discussed MANY times so have no idea how you couldn't find info via search.
All you need to do is..
a) Power off phone
b) Hold Volume down button
c) Press (do not hold) power button
d) Once Tri color boot screen is up, plug in USB cable.
e) Flash stock ROM from HTC site.
DONE!
I am sorry.... But Thx i Just did that and Its back to Win Mob !

Make sure you use HSPL 4 to revert your HSPL back to 3.03.0000 SPL before sending it back in. If yocflash the most recent T-Mobile update ROM the 3.14 ROM you need to reflash it via SD card as it has SPL 3.10.0000 and HSPL 4 does not have that SPL version in it. Bit flashing via SD card will give you this SPL version if you flash the ROM I am speaking of.
To flash via SD card right click on the ROM and select rename and rename it to a .zip file and hit enter. Then right click the file again and select view, find the RUU_signed.nbh file and copy it to the root of your SD card. Don't forget to go back and rename the original file .exe again so you can use it later if you need it again. After you have copied the RUU_signed.nbh to your SD card use your File Explorer to find the file and rename it to LEOIMG.nbh. Next turn your HD2 off and hold the volume down button down while you power your HD2 back on and as soon as you see bootloader and searching on the screen let the volume down button go and follow the on screen instructions.
This will have you 100% good to go for a warranty exchange or repair.
Hmm, So you want me to take the stock Ruu File that i downloaded from t-mobile and rename that to leo.img....the HSPL on there is currently it shows -2.08.HSPL
in the triloader screen? I am still confused on what to do exactly... i already reformatted the phone with the stock Ruu. And thats what the HSPL is that shows on the Tri Color boot screen of the phone.

Yes you need to revert the HSPL back to SPL. HSPL is a custom SPL and you do not want this on your HD2xif youcare sending it in for warranty replacement or warranty repair. The twocways of reverting it is to flash the official ROM via SD card or use the HSPL 4 utility to revert it cause you can flash SPL as well as HSPL with it. But I recommend you use the SD card flash as the SPL with the current T-Mobile upgrade ROM is 3.10.0000 and HSPL 4 does not have this SPL.cGocto the below link if you are still confused about flashing via SD card, it will explain all.

make its the .nbh file that your renaming to LEOIMG.nbh ... dont just simply rename the .exe file
Well the file i downloaded it seems to just be an .exe file... thats the one i was gonna rename to .nbh... that file is the same one i used to reformat the phone back to win mob 6.5

You havecto rename the file you downloaded. from .exe to .zip and then you can explore the file to find the RUU_signed.nbh file.

the exe file is just an archieve that with in that is the .nbh file.along with the radio and the update software.. you just need to extract it using winrar or prob changing the extension from .exe to .zip... once extracted the file.with the .nbh extention is the rom.. the bootloader will only recognize .nbh... so just change the .nbh file name to leoimg and move it to the root of the sdcard and once in bootloader mode it will detect the file and flash it and remove the hspl
Ok, So i put the leoimg.nbh in the sd card booted to the Tri loader and its just stuck on that screen... its not currently connected to the computer... it says serial on the white part of the screen... How do we get it going... or start the process?
You guys said it should search after letting go of the vol down button but its not moving from the screen and theres a 1gb sd card.

? make sure the .nbh file you renamed was the rom (largest one) and that you didnt just rename it to leoimg.nbh.nbh because thats a common mistake and try naming it LEOIMG capital letter... but thw bootloader should load up the file without any input from you
Also make sure it is on the root of your SD card.
How do we get it on the root... i just copied and pasted it to the micro sd card... and its all in caps! Also it doesnt just start up

Yhe root of your SD card means it iscjust on the SD card and not in a file. So when you view your SD card you should be able to see it with out having to open a file.
oK, So, i renamed that RUu file which i made a mistake in putting it in .zip and re extracting it because i had found another Leoimg.nbh file that i tried using so, I reformatted the sd card to fat32 and but the one i found of the Ruu file.... and renamed it the "LEOIMG.nbh" and re did it... And now it picked it up its installing Radio V2 Rcust bootloader splash 1 os config data...so we shall see what happens...!
Ok, it said Update Success... Does that mean i am done after that or do i have to do anything else?!

[Q] Flashed back to windows mobile but auto reboot at htc boot screen.

So i formatted my sd card to NTFS and put LEOIMG.nbh into my sd card.
Now i booted my hd2 in boot loader screen and started the update.It complete sucessfully.
But after this,it reboots and when htc logo comes up with the white background,it auto reboots again.
Why is this and how can i fix this ?
Also if someone can give me the download link for the stock rom for HD2.
Can you still get in to bootloader? If so, I'd try it again. And here's the link...

Although you're probably better downloading direct from HTC with your IMEI number - that way you'll get the right one (in theory)...here's the UK link - not sure where you are in the world...>
http://www.htc.com/uk/supportdownloadlist.aspx?p_id=297&act=sd&cat=all
by the sdcard method you ned the correct rom for your hd2.
if you will flash another /custom rom, you need to reinstall hspl 2.08
and then flash your rom by the daf / ruu fläsher from windows and not by sdcard.

Can it be that i formatted and transfered the LEOIMG file when in USB mass strg in MAGLDR 1.13? because i dont have such card reader or adapter.
Oh and also when i boot after the leoimg was done,it boots and displays some numbers at the bottom.Also the phone wont switch unless it connected with USB.
My current SPL is 1.42 0000
