[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...
I followed all your steps.. more then once. But every time I tried, I failed :[

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".

What have i done !!

I decided to go from Android to try wm7 mango and have messed up big time i think.I am at the moment on the tri colour screen and stuck a serial even though the usb is connected so i cant do a task 29 or anything else.I was on hpsl 2.08 to run android.I have tried to go back to win 6.5 via the memory card method which has put spl 1.66 back on but failed with the update.On the tri colour screen the message is "Upgrade rom code error please try again"
I am totally stuck at what to do next just to get my phone to boot into anything.I need to get the tri colur screen to show usb somehow so i can fix this mess i have just done.
Any ideas and thanks

I also get a 0028002 not allow msg when i try to boot a original 6.5 Rom via the mem card if that helps matters

Ok don't freak out your problem sounds very solvable. First the Serial in the white bar of the bootloader screen is not changing to USB because you do not have the drivers on your computer, this is the only reason you will ever have this problem. To solve it you have two choices.
One go to here and download Windows Mobile Device Center and install i on your computer. It has the drivers you need in it. I could not find the official download from the Microsoft site, they may have taken it down I don't know. If you have Windows XP on your PC you will need to down load Active Sync google and you will find it.
The second choice is to go to here and download version 4.1 of the HD2 NAND Toolkit by XDA Recognized Developer ksubedi. Install the toolkit and open it then look at the bottom right hand corner of the toolkit window and click on the Download Drivers button and you can download the drivers from there. You will have to unzip the file and run the installer to do this.
Also what HD2 do you have, is it a TMOUS or a EU HD2? this will help me know what ROM you can use to flash a stock Windows Mobile back to your HD2 being you now have SPL 1.66.

Thanks for that I am getting the drivers now.I have a EU hd2 and am wanting to put any win 6.5 custom rom on as i was trying to give wm7 another go.
Thanks Again

Sorry for the tad late response. Seeing how you have SPL 1.66 you can still use the HSPL 4 to flash 2.08 HSPL back to your HD2 and then flash anything you want be it a stock Win Mo ROM, Custom Win Mo ROM, MAGLDR, or cLK. You can also use the HD2 NAND Toolkit to flash HSPL 2.08.

I can't install the drivers as I am running 32bit windows 7 and they wont install on my laptop is there anyway around this thanks

No, install is fast & simple, maybe you have virus software causing issues with install or problems with your windows 7 OS ...

I think its time I had a format of my computer and start a fresh its been running really slowly lately.
Thanks for all the tips got my beloved HD2 running again even after dropping in a sink full of water and in the airing cupboard in a bag of rice for a couple of days seems to have sorted it out.All indicators are red yet she still lives !
Thanks all

[Q] HTC HD2 bricked, can load bootloader cant install any ROM

HI everyone,
This is the first time for me posting a thread here...thanks in advance.
Well I have a HTC HD2 that is a friends of mines. He was trying to change the radio so it could work in another country and managed to brick the phone. He got tired of trying to fix the phone so he gave it to me. I have tried fixing it with a tool kit I downloaded in another thread here. I managed to get it to boot butt it wouldn't get past T-Mobile screen...I kept on messing with it trying to install a ROM and different radios but non will work and wont turn on anymore but still is able to be recognize but PC(not mobile media center) and the last thing I did was task29. It stopped at 99%...still can load bootloader 3 colors but having a harder time getting the phone recognize by PC. Can anyone help me before I get into a deeper hole? If your need any more detail please ask me...btw the phone is running SPL- 3.03 HSPL in boot loader.

to the rescue !!

your friend shouldnt have flashed the radio without proper info !!
radio is the only thing which bricks the device !!!
dont worry we'll try to sort something out !!
firstly start with flashing a proper radio !!
http://forum.xda-developers.com/showthread.php?t=611787
download the radio 2.15.50.14 from this thread and flash it !!
NOTE : if you cant flash radio from ur pc, via nbh installer or the toolkit, you can flash it from a memory card !!
just format a normal memory card, put the radio on the card, rename the radio file to LEOIMG.nbh and get to the bootloader screen !!
follow the instructions from there and flash the radio !!
secondly if you want android or wp7-7.5 on ur device !! hspl 3.03 wont work !!
so install hspl 2.08 for that !!
for winmo6.5 3.03 is ok !!
do a task 29 once and flash any rom or magldr(for android or wp7-7.5)!!
good luck .....

thanks for quick reply
I am trying to do what you instructed me.

Didn't work
I tried it on the PC and it sadly stopped @ 96%, now it wont turn on volume down+power. Battery was charged and i didn't turn off. It displayed error 262. as soon as I can I will try it on sd card. Thanks though.

I was not able to install the radio but did in fact get to task29 successfully and MAGLDR Version-1.13. Now my phone is stuck in the Stick together screen. Can anyone help me from here what should I do. thanks I will be waiting for a responce.

Do you still need help cos its really easy to unbrick your phone and I say this because once I flashed 5 different roms in 2 hours or less and my phone wouldn't even turn on and when it did it would get stuck on the tmObile splash screen and restart but I fixed it and now I'm running the best Rom out there lol... reply to this thread and I'll tell you what to do

The thing is that I can't get any ROM's to finish installing...in the SD card the power button does not work...and in the computer the fartest I gotten was 99% but always stops and gives me error ussualy Error 262. Ireally don't know what to do. MY friend said he took it to an Asian Guy...I noticed that the battery S/N does not match the phone...can this have an effect...I haven't been able to flash any ROMS successfully not even the debranded stock. I flashed several phones and installed many different custom firmwares but this phone has been a real challenge...I'm over 2 weeks in...Thanks for the help thus far you guys are the best...

leoimg.nbh won't start to install
Hi everyone,
I have a severe problem with my HTC HD2 after installing a NAND version of android which did not work very well, than wanting to reinstall winmob 6.5 (vodafone) it startet "loading" the leoimg.nbh from the SD-card, but than stayed in this status neverending. So I interrupted (was that the mistake?? :-( }. Now I'm able to start MAGLDR 1.13, am also able to install another NAND version, but with every version I get the message: problem with android.xxx and so on.
I can start the bootloader modus (SPL-2.08.HSPL 8G XE), also connect by USB, but if I try to reload any leoimg.nbh from SD card - it does nothing, just stays in the bootloader modus.
Did I destroy any hardware by interrupting the non functioning "loading"?
Please help, if you can, what I could do now to get a functioning NAND android again!
Many thanks in advance!!!

freak just try the task 29 and u might return everything to normal condition
and for future never interrupt the installation process as u can brick ur device
for the main topic, i can say that ur device is fully bricked and the only way is taking it to the service center or try flashing directly into the hardware, but thats dangerous and requires professional skills

Plz help!

First of all; This steps can solve your problem. But first of all(don't forget to check 2.08.HSL) try to use "Task29" and if it is success, load Radio ROM 2.15.50.14, and load original Winmo 6.5 ROM (Tmous or EU which phone do you use).
If you are stuck somewhere, then;
Download an original ROM for your HTC device from HTC webside.
- Format your SD card like FAT32 primary.
- Take "RUU_signed.nbh" from an original ROM and copy it to your SD card.
- Rename to "leoimg.nbh"
- Reset your device while pressing the volume down button.
Radio ROM 2.15.50.14;
Radio ROM 2.15.50.14
HD2 Toolkit 4.2.0.1; ( contains task 29, magldr and recovery and also HSPL)
HD2 Toolkit 4.2.0.1

it's revived!

After several attempts to switch on the phone it finally turned on so I immediately installed stock ROM and it didn't get stuck on 0%.. it worked!!
Do you think I should perform a task 29 now or I can just proceed with installing a new radio and then installing a new ROM?
Thanks again mate!
Apparently I need to install SPL 2.08 before trying to install HSPL and then run android.. anyone know where I can find it?
Nevermind figured everything out Thanks anyway

If you want to change your ROM with one another like Android NAND ROM or Windows 6.5 ROM, then use this procedures.
For NAND Android ROM; You must flollow this sequence;
first check your device if it is 2.08.HSPL, and format your sdcard ext3 or ext4 and 1gb (which one you must use is pointed out by your Android chief). Copy new Android ROM into your sdcard's FAT32 section. insert it into your HTC device.
1. do task29
2. instal radio rom 2.15.50.14
3. install magldr 1.13
4. do recovery 5.0.2.6
5. do clear cache and dalvik cache.
6. Choose your android ROM .zip file on sdcard, load and enjoy...
For Windows 6.5 Follow this sequence;
first check your device if it is 2.08.HSPL, Format your sdcard like FAT 32 primary partition. insert it into your HTC device.
1. do Task29
2. Install Radio ROM 2.15.50.14
3. Run LeoCustomRUU.exe like "Run as Administrator" which Windows 6.5 rom you chose to use.
Radio ROM 2.15.50.14;

Are you booting into bootloader and connecting the device to your computer so you can get the HTC Sync connection. Just boot into bootloader by holding the volume down button down and poewering on your device. Connect it to your computer via USB and when you see Serial in the white bar of boo5tloader change to USB you have the HTC Sync connection and can flash your device.

I face a very odd problem with my HD2 EU. After years of 2 different versions of Android on nand I decided to reset it to stock(Vol down+power with leoimg.nbh in root of a FAT32 formatted microsd). When I get in bootloader mode there seem to be 2 instances of bootloader. The first 3 colour screen with all the right wordings lasts a second or two then I get a second 3 colour screen with the same wordings. With my Verbatim 8Gb class4 microsd formatted FAT32 and leoimg.nbh (obtained from the original RUU_Leo_HTC_ITA_1.66.408.1_Radio_15.32.50.07U_2.07.51.22_2_Signed_LEO_Ship.exe) in the root directory, the device does not recognize the file and it's not possible to restore the phone to stock, but I can only get into usb connection.
Being able to get in usb mode with the various versions of HSPL (1-2-3-4) I can still change the bootloader. With the HD2 Android toolkit 4.2.0.1 I can install cLK, Magldr, do a Task29 and repartition.
When I use the RUU installer I can install the RUU_signed.nbh that I used to get the leoimg.nbh BUT when I do it, and it does finish gracefully, on the screen that states the currently installed image THE INDICATION OF SUCH AN IMAGE IS BLANK whilst the name of the image to install is the one I am flashing.If I reflash the same image AGAIN (so I know what's on the device) the info of the installed image is never displayed.So after trying the various bootloaders HSPL and SPL and getting the same result you are my only resort.
Has anybody experienced such a problem? It is as if the the bootloader goes through a script that then starts a second "identical" bootloader (I understand that I may seem crazy) that is not capable of recognizing a leoimg.nbh. All my buttons are still working so it's definitely not a button problem. Therefore in a nutshell the question is: if I can't get the device to recognize a leoimg.nbh is there any other way to make it do so, given that I can communicate via usb without problems ?

need to restore to original OS

have android 4.0 on HD2 and it sucks bad..
how do I restore back to original OS windows 6.5

1. Download any WM 6.5 ROM for your phone you like,
2. power off your phone,
3. power it on while holding vol-down button (you should see 4-colour "matress"),
4. connect hd2 with usb cable to your desktop PC, run WM6.5 flasher.
5. Done... ))

i do that but the flasher says this after it recognize the phone and start flashing it stops and says this error{226} the update utility cannot get response from your PDA phone. please check that your ubs craddle/cable is connected properly between the pc and your pda phone and also check your pda phone.

For custom rom. try this.

I flash my hd2 using energy rom dinik. with radio 2.12.50.02_2.
So far I have not encountered any bug like freezing of lcd.
Thanks NRGZ28 for the rom and PG101 for the detailed instructions to install custom rom to my phone.

Yeh I would recomend NRG wm6.5 roms too, best wm6.5.3 experience available & it works perfect.
Try flashing via sd & check you current HSPL & radio are suitable too ...

yeah im actually trying to flash a wm6 from NGR but then again this phone have nand android installed and when i try to flash the wm6 ruu the flasher stops at 0% and says that the phone its not connected, after it showed it did before i pressed next, do i need any kind of drivers?
i have ht drivers from my sensation are they the same? i am a total noob for this phone and i dont like the ics thats why i wanna go stock while i learn little by little how to do things with it.

Flash via SD card method is probably way to go but take care with radio versions if a TMOUS HD2 or you will brick it.
You could install ActiveSync if XP or WMDC6.1 for Vista/W7 as it has drivers.

you can do a factory reset which should fix the problem

I think my phone is bricked? please help

Everytime I turn on my phone, it goes straight into bootloader mode. I don't know what to do. I've been trying to google for the past hour or so, and no luck. Can anybody help?

Could be that your vol down button is stuck, try pressing and releasing quickly a few times ...just a thought!
PS. Your phone is not bricked if you can get to boot loader!!!

i tried that, and it didnt work. any other ideas?

can anyone please help?

Maby you don't have an OS. So try to flash a stock rom.
Sorry for bad english.

i tried that, but it either loses connection or it will say something about, how the the version of the o.s doesnt work for my phone. also on the phone itself, when it tries to download the rom, where a htc image is normally there, it isnt.
i have no idea what to do

It would be helpful to understand what you were running on your phone before the problem occurred?
The Bootloader you are seeing - I assume it is the hacked Cotulla one?
If you connect your phone to a PC does the bootloader screen show "USB" rather than serial?
If you have Cotulla bootloader and USB connection to PC, I'd start again with a clean install....not sure what you were using...but Typhoon is nice and Stable

It has a "clean installation" guide that you can follow....

HTH.

I was trying to reinstall a stock gingerbread o.s on the phone, but something happened, and it wouldn't allow me to. So i just wanted to reinstall stock tmobile rom, and install android after that.
Yes i have cotulla bootloader, and whenever the phone starts up, it says serial, but it ill change to usb when i plug it in.

i couldnt open the pdf file.

If you are getting errors while flashing the stock ROM, as in windows mobile, then 99% of the time you have bad NAND memory and the phone needs to be jtaged or the motherboard needs to be replaced. Ive experienced a lot of these similiar threads over on PPCGeeks with the HTC Touch Pro 2

whenever the image file tries to update through bootloader i get an error/update image fail due to the radio i think. it says its spl 2.08 hspl, i tried uninstalling hspl but that didnt work. what could be the problem? or am i pretty much out of luck?

Those mirrors do seem broken.
Well this thread gives step by step instructions.
http://forum.xda-developers.com/showthread.php?p=11097380
you have HSPL, so you need to task29, MAGLDR, CWM and then a ROM.....it'll be interesting to see if you get anywhere....
Suggest following it step by step and seeing what happens before we write off your phone!

im not able to install magldr or a new rom, it either loses connection, or says it isnt compatible

Well if you have Cotulla HSPL, and USB shown on that screen, and are connected to your PC and Task29 is not running then I'm afraid I'm out of knowledge....
Sorry.

so i found that i have a ruunbh error, what do i have to do in order to fix this?

with ruunbh I suggest you go back and flash a stock WM rom.
That has worked for some.
If that gets you back running (at winmo 6.5) then you need to start the Android process again....
......By starting with HSPL and moving on through task29, radio, magldr, clockworkmod and a android rom.
going back to winmo is described here:
http://forum.xda-developers.com/showthread.php?t=935145&highlight=stock+rom
Let's see if you can go back to winmo first!

it keeps giving me an update error, when i try to install a custom wm rom and official rom any other suggestions?

So of the steps below....where and what is the update error?
--------------------------
If you are using a 512MB ROM HD2, just download the official firmware from HTC's website. The recommendation is to use a 1.xx or 2.xx ROM, do not use a 3.xx ROM.
Download 7-zip, make sure it is 9.20 version and up.
Using 7-zip, open the official ROM update exe file. Do not execute it.
Inside you will see RUU_signed.nbh, extract just that file. Nothing else.
rename RUU_signed.nbh, to LEOIMG.nbh
Copy LEOIMG.nbh into your SD card root directory which is FAT16 or FAT32 formatted.
Unplug the battery from the HD2, count to 10, replace the battery.
Hold the VOLUME DOWN button, DO NOT LET GO.
Press the POWER BUTTON, then let go.
Follow the instructions on the screen when the device goes to RECOVERY mode.

im using tmobile u.s version

You really like being brief don't you.
