[TUT] NAND Android on your HD2

How To Install A NAND Android ROM On Your T-Mobile HD2​
(I am linking to several Original Threads in this tutorial. The "Nice Thing To Do" is hit the "Thanks" button at the bottom of those threads to let the author know we appreciate their help)
mskip wrote an excellent tut over on the Leo forums. I used his instructions to create my own method, which has never given me issues.
My method has been used by others and has a 100% success rate as of this writing.
You MUST be HSPL'd. This is not a joke. If you attempt this method without HSPL, your phone won't boot. I can not help you if you do this. If you have the 3.14 radio, try flashing: this stock ROM before HSPL. Thanks to xmoo for the link! Original thread is here.
Read the following steps. If you're confused, read the explanations below.
(Preparing)
Folder: Create a new folder on your Desktop. I named mine Flash. Put all downloads here.
HSPL: Cotulla's HSPL 3 is located here. (Original thread is here)
Task29: Download the Task29.exe program located here. Unzip it to a new folder. Replace the RUU_Signed.nbh file with your favorite radio. I use 2.15.50.14 (Original thread is here)
MAGLDR: Get MAGLDR 1.11 (or the latest version!) located here. Unzip this to a new folder.
ROM: Visit HD2 NAND Android Development thread here on XDA and download your new ROM. I am currently using this one, but will probably have a different one tomorrow Unzip this to a new folder.
SD Card: Back up everything you want to keep from your SD card, and then format it. Hint: dcim is where your pictures are stored (File System: Fat32, Allocation unit size: 16 kilobytes) Personally, I like to uncheck the "Quick format"; it takes up to an hour but ensures my card is in the best shape possible. Once your format is complete, you may replace your backed up files.
(Flashing)
(*Optional: Remove your SD and SIM cards, if you are paranoid, like me )
Connect your phone via USB to the PC and wait for any drivers to install.
Task29: Navigate to the Task29 folder and right-click on task29.exe and "Run as administrator". Your phone will reboot to the initial flash screen. You will have to reset to Bootloader.
Wait for your PC to update the drivers again.
MAGLDR: Navigate to the MAGDLR folder and right-click on ROMUpdateUtility.exe and "Run as administrator". Your phone will reboot to a new boot screen.
Wait for your PC to update the drivers again.
You should be booted to the new MAGLDR screen and see a series of options. Use your volume rocker to highlight "USB Flash" and press the green call button to select it.
Wait for your PC to update the drivers again.
ROM: Navigate to your new ROM folder and right-click DAF.exe and "Run as administrator".
Congratulations! When your phone reboots, it should start MAGLDR which will immediately boot your new Android NAND ROM!
Now, here are the details about the above instructions. You should only need them if you are confused.
(Preparing)
I use this to keep myself organized. I own several HTC phones and flash them all, so keeping things separate is a must for me.
Having a Hard Secondary Program Loader is a must for any NAND flash, whether it be Windows Mobile or Android. This will void your T-Mobile warranty, but can be fixed by flashing a Stock T-Mobile ROM via your microSD card. Check my sig for the tutorial link on how to do that.
This is the easiest method to do a task 29. The other is using mtty, which is beyond the scope of this tutorial. Task29 completely erases the existing files and partitions, preventing any loose data bits from causing issues with a new flash. You should always Task29 between NAND ROMs.
MAGLDR: A group of devs have been working on a NAND loader for some time and Cotulla and the Dark Forces Team (DAF) were the first to release a working loader. There may be more to come in the future, but this is the first (and has Tetris built in )
You should never ask the "best ROM for my phone" question. Every chef works hard on their build and considers it the best. Every user has their favorite chef and considers them the best. You should shop around to find the one that fits you best.
I consider formatting the SD card a must if I have any data written to it by a ROM. If you have installed Android to your card, you definitely want to do this!
(Flashing)
Your phone will boot into several different modes throughout the process. Each mode may require separate drives for WMDC to talk to it.
To reset to your bootloader, pull the battery and replace it. Hold down the "Volume Down" rocker and press the power (End Call) button. The phone should boot up to the tri-color screen. If it did not, keep trying!
Your PC may not need to search for drivers at this point, but wait and see anyway, just in case
MAGDLR will work as your new bootloader, but you can always access the original tri-color bootloader if you need to.
Don't worry if you get the missing "ADB" driver warning here. Only PCs with the Android SDK properly installed will have this driver.
You must flash your new ROM from the #4 screen via USB. It is the only way and the tri-color Bootloader method won't work here.
Again, you can ignore the missing "ADB" driver if it occurs. See above x2 for explanation.
Some chefs are renaming "DAF.exe" to "Install.exe" or "ANDR_INSTALL.exe". No matter what it's named, it should be the blue icon. See your ROM thread for detailed installation instructions if you get confused here.
Hope this helps!

Thanks for the plethora of information. In this case, it wasn't needed but most of the time it is
Error 262 means there is a link error between your phone and the PC. Some have solved this by re-installing ActiveSync or Windows Mobile Device Center. Some people said it was solved by simply unplugging the phone and trying a different USB port or cable.

After installing android rom in nand, device continously reboots
I followed all your steps and installed everything (there war an error encountered while installing the rom in the last step) but when my phone boots into android, after about a minute it will just restart itself and continue the same over and over without ever fully going into android.
can you please tell me how to get over this?

It looks like the Android build you chose is either incompatible or was somehow corrupted when you downloaded it.
I suggest you delete the copy you have on your PC and download a different ROM, and then start over again.
Since there was an error, you don't want to try a fresh install without a task 29 and reinstalling hspl.
If you are using the Euro version of the HD2, don't try to install a TMOUS ROM, and vice versa. If you aren't sure, ask the chef who posted the ROM you want.
Hope this helps!

Radio Version
2.07.50.27_2
I think that the RADIO has to be 2.08.50.xx or a .50 greater.

One thing that was specified but not in the steps was HSPL. If you don't have that, you can't flash.

After having a bit of problem using the original tut you reference in your first post(basically it got locked on gogogo and a variety of problems thereafter), I am very happy to report that your variation on the method not only worked for me, but worked on the first attempt. And it has thus far done so each time I have tried it since. You cannot imagine my relief after all the frustration I had previously. So just wanted to let you know how helpful I found your post. Thanks!
The only edit I would suggest is that I believe USB Flashing is option 5 now instead of 4.
FWIW I was originally on ROM 2.13.531.1 (90963) WWE with Radio 2.10.50.26(now on 2.14.50.04).

I just tried a fresh download of MAGLDR 1.11 and the option is still #4. Did you perchance grab version 1.12?
It would still work, but 1.12 gives you the additional option of installing and Windows 7 Phone ROM.

Yes on MAGLDR the option is 5 instead of 4.
Other than that, and the part about removing your sim and SD card, looks like an excellent guide.

I am updating the tutorial to reflect on the changing menu numbers, thank you!
As far as the SIM and SD card removal, I did mention that this is optional but recommended. Yes, I realize that this is from the early days of flashing and is more than likely not needed, but in my defense this is my own method and I have never, ever had a bad flash. I've owned several HTC phones going back for a few years now and have not bricked a single one. I would consider that a pretty good track record, considering the number of posters who did brick their phone and have no idea what went wrong.
In light of your input, I will re-word the OT to ensure that the "optional" part is clarified.

Oh I totally hear ya.
I've never had a bad flash either. I think that some of the "Brickensteins" just do something wrong and don't mention it (like unplugging the phone mid-flash).
In your favor, I did read in one of the WP7 tutorials that the sd card should be removed, but since I don't plan on flashing that any time soon, I'll leave that wisdom with wiser hands

Thank you very much

Ok do this hold the volume button down while powering on your HD2 and see if the multicolor bootloader screen comes up. If so you are not fubared. If you get bootloader you can save your HD2. Click on my Guide linked in my sig and read it then click the links at the top of my guide if you want to install Android or the link for WP7 if you want to install it. The links I have at the top of my guide are links to very good and extensive guide. If you want come post back here and I or others will help you and if you want to just PM me.

Please Help me...

You are using MAGLDR 1.13, not 1.11. On 1.13 (not covered by this tutorial), you have to choose "ROMUpdateUtility.exe", not "DAF.exe".

[Q] struck at white screen while installing ANDROID

hello, I was trying to put the android on my phone with the attached files but landed in a very awkward situation. my phone is not going ahead from the white screen saying HTC.
It seems that I don't have the operating system in it. as earlier when the white screen turns up i got the rom version number which i am not getting it right now.
moreover when i try to flash the original ROM iti not taking the current and updated rom version number just an empty space. can anyone help me regarding this issue.
i am unable to upload the android file as it's size increases the lotted size, it's name is DFT LEO NAND ANDROID.
I IWLL BE VERY THANKFUL TO PERSON WHO RESOLVED MY PROBLEM.....PLEASE HELP ME

Firstly, you have posted this in the wrong thread.
Secondly, don't worry, your phone is ok.
Thirdly, the information you need is in this thread. Read it carefully.

Are you sure that you installed the radio and that you did this after installing hspl? Your bootloader screen shows that you have 2.08.hspl, which is correct and you have the attachment for the correct radio. I suggest going back to bootloader and reflashing the radio (just to be sure). Which magldr version did you install and did you install it as Administrator? You should use magldr 1.11. After installing magldr, the phone should boot into the magldr boot menu. You can read the full step by step process here.

yeah i noticed after you said... anyway now it is posted and what can i do

need help
when i am trying to flash the rom after downloading it from the thread you mentioned I am getting the screen attached below as an attachment. is it right

Well, since you ask, go and read what they pointed you to.
In 90% of the cases it is a small mistake from our part that leads to these problems,
so even if you think you did everithing as iot was supposed to be, read again and reflash everything.
There is this new and verry good installer here - it can do everything you need, it's LeoAdvancedRUU 1.0.4 - search the forum for the thread.

need help
thanks for the help lms1407.
after going to reflash of my memory i will tell u what i have done step by step. i iwill make sure i will not miss a single step.
1.download all the files ....HSPL,ROM AND ANDROID ROM.
2. FLASH THE HSPL WHILE IN ADMINISTRATOR ACCOUNT. PUT THE PHONE IN THE BOOTLOADER AND FLASH THE HSPL WHILE CONNECTED THROUGH USB.
3. NOW WHILE TRYING FLASH THE ROM IT SAYS THT IT WILL TAKE 10 MINUTES TO DO THAT BUT MINE ONE JUST COMPLETED IN LESS THAN A MINUTE. I MAKE SURE THAT ALL THE SCREENSAVERS ARE NOT DISABLED AND WAS CONTINUOUSLY WATCHING THE PROCESS.
THIS IS A TIME WHEN PROBLEMS STARTS. AFTER THAT WHEN I TRIED TO REBOOT IT STRUCK IN THE WHITE SCREEN HAVING HTC LOGO. THEN AGAIN I TRIED TO FLASH THE ROM WITH SAME VERSION BUT THIS TIME THE CURRENT AN D UPDATED VERSION NUMBER WAS NOT COMING UP OVER WHERE THEY ARE SUPPOSED TO BE. I AGAIN CLICK NEXT AND FLASH THE ROM. AFTER THAT ALSO MY PHONE IS STILL ON THE WHITE SCREEN WITH HTC WRITTEN AT THE CENTRE.
4. I TRIED TO INSTALL THE DFT ANDROID BUT WAS GETTING AN ERROR. FILE ATACHED.
AFTER THIS I AM UNABLE TO DO ANYTHING. THESE ARE THE STEPS IN DETAIL WHICH I HAVE FOLLOWED OR HAD DONE WHILE INSTALLING THE ANDROID.
CAN U PLEASE TELL ME WHAT I HAVE DONE WRONG AND WHERE I MADE A MISTAKE.

Both myself and nobnut referred you to the guide for how to do this. Please read and follow those steps.
Exactly what stage are you at? You mention trying to flash hspl and then the next minute you speak about flashing the rom, what about all of the steps in between?
1. Flash HSPL - 2.08.hspl (check bootloader to ensure it shows 2.08.hspl and not 2.08.0000)
2. Flash radio 2.08.50 or higher .50 radio
3. Install magldr 1.11 (Run as Administrator)
4. In magldr go to option 4: Usb flasher
5. Let usb drivers install
5. When screen shows Wait USB......USB, then AND ONLY THEN flash the rom (again as Administrator).

You really need to read the instructions I linked to in post 2.
Step 1 - Stop using CAPS!!!
Step 2 - Read the instructions posted
Step 3 - Boot into Bootloader by holding the volume down button while you power on
Step 4 - Flash this Radio (version 2.15.50.14**)
Step 5 - Flash MAGLDR (see instructions linked to in post number 2)
Step 6 - Flash your desired Android ROM
Step 7 - Read the instructions

Don't write with caps on, please!
Did you flash radio again? Just in case....
First of all, after flashing hspl you have to go in bootloader and then try to flash Magldr 1.11 and then go in magldr by holding the power button while magldr menu shows!
Then choose usb flasher - number 4 in the menu - select with left hard button - then when it say usb... you have to connect the usb cable
and then open the directory on your computer, where the actual android rom is
- important -
unpack the original archive that you downloaded, dont reuse the same directory, because some files might be missing!

first no caps........thanks
second by rom i mean radio my mistake i apologize for it...
third at the start of this thread i have uploaded the files and screen shot which i have used and getting problem respectively.
fourth can i start from the beginning because when i start doing that i am not getting the version number which i am using in the screen as attached earlier. is it alright?
fifth i want my phone back guys you are great people help me in this matter.

Your picture is so small and blurry that nothing can be seen on it.
As long as you can still get into bootloader you can still do the steps. Just follow them.

yes i flashed the radio twice.
i am now understanding the things. first step is fine but when i am flashing the magldr after that a reboot is normal or not. because i am facing reboot and wite screen with htc logo and nothing else.

guys u rock.... u are trying to help me.... i appreciate that. thanks i am also trying my best to overcome this issue and understand where i have made a mistake.
sorry for the small pic as i was trying to compress it. can u please open this pic in paint. i am sure u can see it clearly. sorry for this

Rather than keep on referring us to pictures that are so small that I can't see Jack, just tell us what the problem/error message is. Are you getting the USB init failure 723 error? Are you running XP? Read post #2 in the links from above, or else click on the FAQ link in my signature

Stop...
I think I understand where you have 'gone wrong'...
Basically, after you flash MAGLDR, the phone will reboot. This is normal BUT you don't have a ROM flashed to boot into at this point so the phone will just hang. Download the Android ROM you want and follow these steps. But only if you are sure you have flashed a Radio:
Pull the battery out of your phone and put it back in.
Press and hold the power button until you see the MAGLDR menu appear.
Then select 'USB Flasher' using the volume button.
Then press the left hand button (send button).
Then plug in your USB cable.
Then flash your Android ROM as Administrator.
The phone will then reboot into Android and you should be ok. (It might take a long time to boot - be patient).

Not if you've already flashed, the winmo rom is no longer there and all data is gone. the only way back to winmo is to flash a new rom.

[Q] New in upgrade mobile, what do I do?

Hi all,
I'm brand new in the art of updating mobiles.
I would like to update my HD2 to andriod but have no idea of how I do it. I have looked at a lot of threads but it seems that I need ot know a lot about my phone before I can start!!
Can anyone help me how and where to start?! What do I need to install and how do I install it :/
My phone data:
OS version 5.2.2.1913 (21913.5.0.94)
Manila version 2.5.20181527.0
ROM version 3.14.403.2 (04666) DAN
ROM date 10/4/10
Radio version 2.15.50.14
Protocol version 15.42.50.11.U
When I press volume down and start my phone it say
PB81100 HX-BC
SPL-3.03.0000 XE
MicroP(LED) 0x05
MicroP(TOUCH) 0x50
Best regards,
Peter

Knowledge is power my friend and d answers u seek are but a click away...All u have 2 do is read, read n do more reading...follow all instructions written by devs to d letter as they were written for a reason...Wat reason?...
Avoiding errors or turning your beloved HD2 into an "Expensive Paper-Weight"....Getting android onto ur device is quite easy, u just have 2 put in d time 2 understand certain terms n how d needed softwares work...So summary?...Start reading from here. When u have properly familiarized urself with flashing then visit the HD2 android development section n check out several builds available...u must make a choice urself as we wouldn't know wat u lyk...so feel free 2 test as many as u can.
P.S. Its crucial u first perform a HSPL (2.08 HSPL) on ur fone before doing ANYTHING else.

The post above isn't really helpful. He's obviously read a lot already lol.
I know getting in to flashing and stuff on the HD2 is very confusing at the start, but once you learn it once you learn it forever.
Basically first off, you need to flash HSPL 2.08 to your phone. To do so download 'HSPL4' from these forums and flash that. Just search for it and you'll find it. It'll have instructions on how to install it on the thread which is very easy.
Just boot to SPL and connect to USB and run the .exe file inside of HSPL4 and choose 2.08.HSPL from the drop down menu.
After this you need to flash the newest radio which is 2.15.50.14. There's a sticky in all the HD2 development threads that have all the radio's. Just look in the WinMo or Android section and it'll be stickied. You basically then open the file you downloaded with the radio in it, boot to HSPL (you've just flashed HSPL over SPL) and run the RomUpdateUtility and just click on all the next and update buttons on the window that'll pop up and it will install. Obviously you need your USB cable plugged in for this too.
After that, you need to flash MAGLDR. I can't get links at the moment but you should easily be able to get a link to the MAGLDR thread and download it. After you've downloaded it to your PC, it's basically the exact same procedure as flashing a radio. Bootloader > USB connected to phone > open RomUpdateUtilty and follow instructions and flash. After this finishes installing you're basically done and all you need to do is flash your Android ROM. Just go in to the NAND Development section and chose a ROM to start from.
Another option is to flash Clockworkmod Recovery after MAGLDR.
You simply flash that by going in to MAGLDR (keep holding power/end key while phone is booting) and go to USB Flasher using your volume buttons then going in to it by the call button. Then opening the .DAF file on your PC and following the instructions and clicking next. Obviously again with your USB cable plugged in too. This is how you flash ROM's/Clockwork.
Any other problems I'd be more than happy to help with.
Just to mention too - the HD2 is very difficult to brick so don't worry about bricking your phone as I don't think there's actually a way to do it other than flashing the wrong radio if you have a TMoUS HD2 and you flash a .51 radio which you won't do as I've told you the correct radio to flash.

from the info he posted about his phone, it seems it already has the latest radio installed (2.15.50.14) I'm guessing that he's got a phone from somewhere in EU since the TMOUS came with the 2.08.50 radio, unless I'm mistaken, and there are some later models of the US hd2 that have the 2.15 radio, but anyways if the info is correct then he doesn't need to worry about the radio, he needs :

Woops my bad, didn't even read the OP info part. Well done for posting the links though as I can't at the moment.
Also about clockwork, make sure the you have the right clockwork partition for the ROM or else you'll get stuck on a boot-loop. You'll usually find the partition info in the ROM thread and then you just edit the flash.cfg file found in your clockwork folder using notepad.

Sometime wrong radio can cause that issue.
Make sure that the radio is 2.15.xxx.xxx.
Now, you should go into bootloader and try to flash the radio, and then restart doing task 29, flashing MAGLDR.
If you succeed, your phone will automatically bring you into MAGLDR screen.
From there you can flash Android or WP7
Good luck

I now downloaded my "old" radio version 2.15.50.14

It seems to complete.. didnt jump from 0% to 100% in 1 sec..... so thats good
Then the task29 seems to work as well since my ROM is clean!!
BUT agian when I romupdate MGLDR it start and complete very fast... goes from 0 to 100% within a few sec...
http://forum.xda-developers.com/showthread.php?t=893618
and agian stops at the HTC startup screen.....

As extra information I can say that when I try to install MGLDR the RomUpdate state that the current image version is... blank
and that I can install Image Version 2.00.000.0
And then when I start it takes a few sec.....

Can it be a problem with the SD card if there are no connection or a defect card?
I get exactly the same behavior if I remove the SD card from the phone!

If the last step you took was to install magldr, of course your phone won´t boot, since you didn´t flash any build the phone could run on?
Or have i missed something?
Normaly, if you are setting things up to install some android build you have to run a file called daf.exe (only as an example, i´ve been flashing just one particular build with magldr), that daf.exe will partition the nand according to the needs of the build, that particular daf.exe was delivered with.
Now you have to enter "ad recovery" from the magldr menu (power on and keep power button pushed) and from there you would have to install from zip.
Have you been that far taking all the necessary steps? Leaving out the nand partitioning with the daf.exe is a common mistake i have read often about.

Thanks so much for those posts.
I think I have damaged the phone now trying things ..!
OK it has been 3 days and nights of trying stuff, let me try and summarise where I am at.
I managed to get magldr working, and used the menus to browse to a ZIP rom on the SD card and flashed it.
It was stuck in a continuous boot loop - see Andriod splash for about 10 secs, then reboot, repeats...
The best way forward from what I could read in threads was to just re install a stock ROM and start again, and try another cooked ROM. It was during this process that it failed, it now seems to have NO firmware on it, as I do not get any radio version numbers or anything.
NOW when I boot the phone - I cannot get magldr. It just goes to the white HTC splash screen and hangs forever.
Everything I try to flash now is stuck at 0% and never completed.
THE ONLY thing I seem to be able to install / get to talk to the HD2 is HSPL4, which when completed gives me the "WE HACKED IT" message. Apart from that I cannot install radios, roms or MAGLDR.
However the MAGLDR flash process DOES show 100% completion, I just cant get it to load by holding power button. As I mentioned above, I DID have MAGLDR working previously but wont play ball now.
Thanks for any tips, I think I need to not look at it for a while.
UPDATE = for some reason, it is now accepting the stock Telstra ROM flash process...?
STILL NO MAGICLDR so I cant load my cooked ROMS.. any suggestions are hugely appreciated.

Hi,
I would suggest KEVIN134's TOOLKIT (Don't forget to thank him)
Read the thread carefully and follow his step by step guide for beginners.
Try to install one of his suggested ROMS.You can always change it at a later date.
At least you will have something.

OK thanks. I have now gotten original Telstra ROM back. I hope to start fresh in the morning and follow your link to the letter. I hope it is a good guide for beginners, as so many other seem to claim that and have no plain english steps or screenshots. I truly appreciate your post, cheers.
Tried that app, it cannot find any of the apps it tries to install/use? Maybe I need sleep.

You are talking about HSPL4, i would suggest you use HSPL3 (http://forum.xda-developers.com/showpost.php?p=6894936&postcount=2).
You know how to flash back to stock winmo? Hold the volume down button while turning on the phone to enter the boot loader, connect with USB and wait for confirmation on the screen below (serial changes to usb), and then flash the stock Rom.
I never used the toolkits, never needed them so i would propose the following steps for you, to start from scratch (so we can take it step by step together, i think we need to have the same base to be able to make a statement about your phone).
After flashing WinMo Stock Rom, install HSPL3 (the one in the linke above, HSPL3_PKG.exe).
Then use task29 to flash the 2.15.50.14 radio.
After that install MAGLDR113 and then, if i were you , i would install coredroid v1.6. (http://hotfile.com/dl/113345298/fb3f69b/HD2_Core_Droid_Desire_HD_V1.6_Release_Version.rar.html)
To do that, enter the magldr menu by keeping the power button pressed while turning on your phone, enter USB Flasher from the menu and after connection has been established, run the DAF.exe which will partition the NAND for you.
After that reboot into cwm, enter the usb mass storage option, copy the zip file on the sd card and from there install from zip.
This procedure has worked every single time for me, maybe it will for you, too?

OK I am back to stock WinMo Rom.
I have HSPL3 installed (not 4, 3 as you say).

You might have to explain this to my feeble mind. I thought task29 deleted all data? How would it upgrade the radio?

Task 29 can be used to flash the radio as well, so these two steps can be taken as one.
All you would have to do is copy the radio in the same directory as the rest (task29) and rename it to RUU_signed.nbh, so this procedure will install the new radio as well.
Take that one from here:

All right, have a good nights rest
Sent from my HTC HD2 using XDA Premium App

Thanks for that extra step explained...
I have read the thread, and downloaded the ZIP that was linked that has task 29 and the radio together. About to do it now.

OK that has completed, and it has rebooted, and now shows the white screen with HTC green logo, and stays there. This right?
I think it is.. as I have now flashed MAGLDR 1.13. Am now downloading the rom you suggested
UPDATE: I am done.. your suggested rom is installed and working!!
I am so relieved.
FYI here are the last steps I took.
* Used the Task 29 and radio update instructions from the link.
Once that was done it was a white screen with HTC logo - I then rebooted into HSPL bootloader on HTC device.
* Flashed magldr 1.13 - was very quick.
THESE NEXT STEPS ARE FROM THE QWORD DOC INCLUDED IN THE RAR FILE FROM THE SUGGESTE ROM - great stuff this doco.
1. After downloading HD2 CoreDroid DHD V*.*.rar, extract it to a folder on your PC of your choice.
2. Turn your unplugged HD2 on and boot into the MAGLDR 1.13 menu by holding down the power (right) button after initial vibration.
3. Using volume down move to number 5. USB Flasher
4. Push call button (left) and enter the USB flasher screen. You will see “USB Flasher mode Wait USB…”
5. Plug USB cable into the HD2, you should now see “USB Flasher mode Wait USB… USB
6. Go to the extracted HD2 CoreDroid DHD *.* folder on PC, and execute the DAF.exe. On newer windows buttons, right click and run as administrator.
7. Press next twice, and the installation will begin.
8. When finished press finish.
9. After the installation your HD2 will reboot into MAGLDR 1.13 menu.
10. Using the volume down button move to down to number 8. AD Recovery and press call button (left).
11. Your unplugged HD2 will now boot into the ClockworkMod Recovery menu.
12. IF YOU DID NOT BACKUP YOU SDCARD DATA DO IT BEFORE YOU PROCEED IT WILL BE FORMATED.
13. With volume down button advance to the advanced menu press left button.
14. Advance down to Partition SD Card menu.
15. Select minimum (512m) maximum (1024m). Your choice which one to use. Recommended is the 1024m, then press call button (left).
16. Select the 0m with the call button (left).
17. Wait until the process is finished.
18. Do not reboot! Stay in the ClockworkMod Recovery.
19. When finished “done” will appear in the lower half of the screen.
20. Press right button.
21. Using Volume down button move to “-mounts and storage”
22. Press end button (right).
23. Move down to mount USB storage
24. Press call button (left).
25. A new drive should be mounted to your PC.
26. Navigate to MyComputer and open the new drive (ex: F: E: G: etc…)
27. Go to the HD2_Core_Droid_Desire_HD_V1.12 folder
28. Copy the HD2_Core_DroidDesire_HD_V1.12.zip to the HD2 sd card root (the new mounted drive ex: F.
29. When finished copying and unmounts is selected, press the call button (left).
30. Press the back button
31. Move down to “-install zip from sdcard”, and press call button (left).
32. Move down to “-choose zip from sdcard”, and press call button (left).
33. Select the CoreDroid_V*.*.zip, press left button
34. Wait till it´s finish flashing, you will then see a flashing “CoreDroid”. Flash options will reappear.
35. Push end button (right).
36. Select “Reboot system now”
37. Let HD2 reboot giving it time. Wait at least +/- 10 minutes.
Once the phone has booted, let the syncs take place, wait for about 20 minutes, then reboot.
Totally worked for me. i thought I had bricked, I though no roms would hold.... this was done in an hour!
Cheech, you are the man thanks so much.

Cheech your help was awesome, it has been your posts that meant I have had a phone for the past week.
Now not wanting to sound ungrateful, but I have to report that ROM you suggested runs really bad on my HD2. Very laggy, even to unlock the screen will hang 2 time out of 3. Oh well, I am starting to learn the same rom on the same hardware can act very differently.. sad face.
If I had to state the function I HAVE to have in my ROM it would be obviously good phone and text ability, music player with resume and bluetooth, a browser, email client, and something to play videos.
Is there a very lightweight ROM that will give me the above functions but maybe run a little better on my HTC HD2 (and are as easy to install as the one I have already tried)? Thanks heaps for any tips.

I jumped in, and using your great direction from before have a new rom on my HD2...
NexusHD2-Gingerbread_V2.8_NAND_(Android-2.3.4)_update
Wow, so much faster and snappier. Love the way Google resynced my apps and some settings!!
Gonna play with this for another few days.
EDIT: seems there is always something.. this ROM not finding my Wireless network. Finds all the ones around me but just wont find mine - even with apps to manage it. My kingdom for a lean ROM for my HD2!!!
Edit 2: Turns out Android 2.3 sets the WiFi channels to end at 11.
Our wireless was higher than that.
Advanced settings and increasing the WIFI channels to the full 14, saw my network straight away.
Took quite a bit of Googling to figure that one out.

Please delete.

[Q] Trying to upgrade to window mobile 7

Here is my story. I have a HTC HD2 and I wanted to upgrade it to Windows mobile 7. I tried last week when I had a bit of time but failed. I follow a web site that gave very clear instructions and links to the necessary software. There were 4 steps with 4 different downloads and I did them in the order they were listed. 1st I downloaded and installed Hard SPL with no problem. Next I downloaded and installed Radio which supports 576 MB RAM with no problem. Next I downloaded and installed MAGLDR 1.3 with no problem. Now came the problem. There was no place to find the windows mobile 7 OS download. I look everywhere and finally gave up. In frustration I tried to load a version of android which didn't work and left the phone inoperable. That was last week.
Starting today I found a bit of software (RUU_Leo_S_HTC_WWE_3.14.405.2_Radio_15.42.50.11U_2.15.50.14_LEO_S_Ship) and I ran this and it put my phone back to windows 6.5. Yahoo! After this I think I've managed to find a copy of Windows7 mango and download it to my laptop. So I was off again. I downloaded a copy of HSPL4 and upgraded the HD2 to SPL-2.08.0000. Next I downloaded Radio_Leo_2.15.50.14 but when I put the hd2 into booter mode (the multi coloured screen) and connect the usb cable and ran the software I couldn't get it to load. The screen goes from Serial to usb, the software runs, the screen of the HD2 changes to the loading bar but it just stays on Zero percent. I eventually get a error result and I disconnect the usb cable and that's as far as I get. Can any one help me. I'd love to get windows 7 up and running on this old handset but I have to say I losing patience. Thanks for any help you can give.

Hello,
First off sounds like you were on the right track.
Spl ... Make sure your spl says Hspl 2.08 without the H at the beginning you will get nowhere fast!
Ok so you have your Hspl, next install magldr (through the tricolor screen) check? Good!
Now after magldr is installed reboot phone and hold down the power/endcall button until you get the magldr menu to come up (usually no more than 10 seconds at most). Now using the volume buttons scroll down to USB flasher (option 5 if mind serves correct). It will say USB ... Usb connect. After that then you will run the DAF.exe to install and all will be done in anywhere from 5-15 minutes.
I think ... THINK from the way I read you were trying to run the DAF.exe from the tricolor and there in lies your problem (if I'm correct)
Hope this helps cheers.

Before setting to flash mode ...scroll down to "services" and select (left hand button on HD2). Then scroll down to "clear SD MBR" press left hand button to select then then press again to confirm.
Do the same for "uselast24nand"
Now back at the main MAGLDR select 5.USB flasher

this is what i did & it ran smoothly
- HSPL 2.08
- Task 29
- Radio_15.42.50.11U_2.15.50.14
- MagLDR
- MagLDR Repartition 300/ 45
- Magldr
- Service
- Clear SD MBR
- uselast24NAND
- USB Flaser
- Flash WP
- Done!
if still the error persist try replacing the SD card coz mine had a problem with Trancend's 16gig card.

getting nowhere fast
1st off I want to thank everyone for their input. I'm a little new at this so I don't really know what I'm doing. There was 3 replies to my post. The 2nd two made almost no sense to me so if everyone doesn't mind I'll concentrate on the 1st post. But even there I wont get very far but at least there is a start there. As I said in my post I loaded HSPL4 and that part seemed to go alright. But it was when I tried to load the Radio thing and Magldr is where things went arye. As I said "Next I downloaded Radio_Leo_2.15.50.14 but when I put the hd2 into booter mode (the multi coloured screen) and connect the usb cable and ran the software I couldn't get it to load. The screen goes from Serial to usb, the software runs, the screen of the HD2 changes to the loading bar but it just stays on Zero percent" I CANT LOAD RADIO 2.15 OR MADLDR! But you say if I haven't got the H before SPL then I wont get very far.....well I don't have an H before the SPL. And why don't I? If I loaded HSPL4 via the booter screen (multi coloured screen) why have I got SPL-2.08.0000 on my phone and not HSPL-2.08.0000? And more importantly, how do I get it?
I have now spent two full days trying to load windows mobile 7 on this phone and all I've done is go backwards! I'm the 1st to admit that I'm not very conversant with the ins and outs of these sorts of thing but I am a reasonably intelligent person, reasonably intelligent and very frustrated.

hi is it English.The Windows Phone7

still trying
Somehow or other, I managed (don't ask) to load the radio and magldr. I found a copy of DFT leo 70. I went through all the steps only to be told the Leo70 wouldn't load (Something about the bootloader). I have run that RUU_Leo_S_HTC_WWE_3.14.405.2_Radio_15.42.50.11U_2.15.50.14_LEO_S_Ship and put the phone back to window 6.5. At least I can still use it. I'm will to have one more try if someone is willing to help. As of now, when I put it in Bootloader mode (the multi coloured screen) the screen says
PB81100 HX-BC
SPL-2.08.000 HSPL 8G XE
0x05
Cotu11ahspl 0x30
Does that sound like a good place to start from? If so, I'd love to know where I'm going wrong from there. Any ideas? Thanks

Perfect!

Thanks for your help. Now I'm going to ask you a question which is either going to tell you how stupid I am or tell you how badly arranged this this forum is. Where exactly is "The HTC toolkit" available for download on the page you gave me the link for? I have gone up and done that page and there is all kinds of info on cLK, magldr and partitions and all sorts of stuff that makes no sense to me (and frankly scares me) but nowhere can I find a link to download a "toolkit". So now I'm asking you questions about where to find the software instead of questions about how to load it! I don't know how anyone finds time to do any of this stuff. Here it is 4 or 5 days later and I'm not one inch closer to making any changes to this phone. From what I had look at, this all seemed like a straight forward bit of work. Hardly! I know this isn't your fault.....but I don't feel it's mine either. I look forward to hearing from you. Thanks again.

Thanks Jonas for the link. I now have the toolkit downloaded on my laptop. Progress!
Now for the rest of the stuff. I've gone back to mengfe post and of course there's a few things that need clarification.
Your list starts with HSPL which we know I have now achieved.
Next is Task 29.....what is this?
Then it's load Radio_15.42.50.11U_2.15.50.14 which I'm confident I can do.
Then it's load MagLDR which I'm confident I can do.
Next is MagLDR Repartition 300/ 45. No idea what this is or how to achieve it. Help please. Thanks
Then it's
- Magldr
- Service
- Clear SD MBR
- uselast24NAND
- USB Flaser
- Flash WP
- Done!
Which I, kind of, understand except where does the "toolkit" come into it?
Thanks again for everyone's help and I look forward the next postings. I'll be honest with everyone, I don't believe for a moment that I'll ever get anything but WM6.5 on this phone (in fact that's probably the best case scenario....if I don't brick this phone completely I'll be total surprise) but if nothing, I am tenacious. BRING IT ON!

Alright
Hspl 2.08 - check!
MagLDR - check!
. NO NEED TO TASK 29 (Because it is recommended to come from winmo 6.x anyway)
Since you came from winmo with radio 2.15.bla bla no need to reflash this!
- Magldr Menu (holding power when booting)
- Service
. - Clear SD MBR
- uselast24NAND
- USB Flaser
- Flash WP7 DAF.exe
BE PATIENT!
after first boot setup (just skip it) you will need to reset the phone (like you would restore any phone if someone gave it to you and you wanted to clear their preference, contacts, etc)
There are 2 ways
1 the easiest - settings
. about phone
. more information
. reset
2 hold both volume up/down together when booting (all the way through go go go) next, (grey screen blue writing) then press volume down, phone reboots
Set up live service ls for market, customize, and enjoy =D

What OS are you using ??
If WIN 7 then remember when running DAF or DWI exe's to right click and select "run as administrator"
Just double clicking it doesn't work

Thanks again everyone for your help. BUT....I have to admit to more then a bit of frustration. Why am I ask to download something call a "toolkit" and the nothing is mentioned about loading it on the phone? I'm going to follow what rubledub has posted and see how I get on but I'm not feeling very confident. Here we go...wish me luck.
On another issue. What is the normal way to get back to the posts one has posted here?

"run as administrator" That was the difference! I now have WM7 working on my HD2. YAHOO! Thanks everyone.

Hey again =D
1 the toolkit contains an all in one place to flash (task29 - pretty much reformat/wipe NAND, flash mag/clk loaders, partition CWM - recovery for android) but since you went about getting all this done separately there is no need for it. We were just pointing you in the direction of one single place to come by these files so as to make this a little more easier.
2 to get to any post you started yourself, anything you have commented on, or even posts users have thanked you on - log into XDA, then go back to the top of the page and right under the search box where it says "find your device" you will see you user name in yellow, click that and then you will see your public profile that will list you with the options I mentioned at the beginning of 2 here.
Sorry not to mention running as admin in windows 7 (kind of thought that would go without saying but then again you can't take much for granted when helping someone with anything unfamiliar ... And I use XP =)
CONGRATS MATE!!! I think you know the ones who will have no problems should you ever need to pm with questions or concerns.
