HD2 Back To Stock Help Please

My touchscreen stopped working. I need to RMA.
I've got MAGLDR v1.13
ClockworkMod Recovery v3.0.0.5
PONGSTER's CM7 NAND build
Holding volume down gives me a screen that says:
PB81120 HX-B3
SPL-2.08.HSPL 8G XE
0x05
CotullaHSPL 0x40
I've researched a few guides and online videos trying to revert to stock. I found a stock ROM and found the NBH and renamed it to LEOIMG.nbh but in the boot loader there are no options to load/flash it.
Am I missing something?
Any help would be greatly appreciated....

connect your hd2 via usb to your pc, wait until "USB" instead of Serial apperas on the bootscreen. Then start customRUU, the .nbh file have to be in the same folder.
...on your own risk. But should work

I attempted this...
Verifying the information on your PDA phone... Please wait....
Then ERROR 260 CONNECTION message.
I am in boot loader with USB showing.

Do you've got the drivers installed correctly?

From the xda wiki:
ERROR [260] : CONNECTION
This error occurs when the RUU cannot make a connection to the device right before flashing. This typically happens when you try to flash a new SPL to your device. Use SoftSPL before attempting the RUU again.

Hi,,
I don't think drivers are the issue here,because in bootloader,the "serial" is changing to "USB".
You need the correct original ROM for your phone and as you have done,rename it leoimg.nbh
This must be placed on the root of a 4GB or less sd card.
Power on holding the volume button down into the tri-color screen(hold volume down button until you see "SEARCHING")
The ROM will start automatically as it reads the .nbh file.

So I must purchase an additional microSD card, other than the stock 16GB one that came with the device?
277,263 MB ROM that was downloaded directly from T-Mobile.
LEOIMG.nbh titled.
I'll attempt to find a smaller microSD.

[Q] stuck in bootloader

Warning absolute noob here.
My HD2 leo froze in bootloader after using HD2Android NAND Toolkit.
Screen reads:
PB81120 SS-B3
SPL-2.08.HSPL 8G XE
0x05
CotullaHSPL 0x50
Computer won't recognize the device anymore.
Next steps to take would be EXTREMELY appreciated.
Thanks!

trying to "flash" stock ROM
I promise I read through the threads before I posted, but you knw how your heart races and U cant think, let alone pick up new terms? welcome to my world...
Anywy, bought a 4GB Micro SD to try to flash [I don't know exactly what that means] my stock ROM again. I'll start with saving stock ROM I downloaded to the SD and plug the battery back into HD2 with the new SD loaded.... Is that flashing?
Thanks to anyone that can help!

back up but would love some trouble shooting
to see what I did wrong and get Android on here. Thanks for an help and all the threads that're out there

To get Android back on do this:
1) download this file http://cotulla.pp.ru/leo/Android/DFT_LEO_MAGLDR113_DAF.rar
2) turn the phone onto that bootloader, then run the RUU file from the download, it should flash magldr.
3) once magldr boots you can flash the Android ROM of your choice from this list
http://forum.xda-developers.com/forumdisplay.php?f=928
You may have to flash a clockworkmod recovery, in the ROM thread it may link you to the right one to flash using the USB flasher mode in magldr.

Thanks!
I'll try that and follow up here for others

I have the same problem exactly.
and the ruu you give told me ERROR (260) : CONNECTION
What can i do?

No one here can solve this problem?

Maybe you don't install your ActiveSync or WMDC v6.1 correctly.
Your phone still working, because enter to bootloader but just no rom in side or error rom so it don't start up.
Please try to uninstall your activeSync or WMDC and restart your PC. Restart your PC and install ActiveSync or WMDC again.
I hope it working.

i've got the same problem..
Very anoying, i was curious about the HD2 Toolkit so i intstalled it and started working with it.
I used task 29 and after that i used clk repartition.
Now i'm stuck at udc_start()
I think because it wont connect usb
Only thing i can do is start into that and bootloader.
But when i'm in bootloader it wont connect to USB
WMDC is fresh so i'm out of options?
What do i need to do

flash stock via sd and try again.

Perhaps the Down volume button is damaged (always pressed and not released and you can not complete procedure to boot from SD) or at worst a shortcircuit board or processor that manifests similar.
I think I've the same problem, but with the UP volume button. I solved it after I uninstalled .dll's volume controller from WM65 (otherwise it beeps continuously and permanently displayed on the screen was the volume controller picture, like as I hold the volume up button continuously) and we could use in normal conditions.
Only the battery ends quickly (the phone completely stopped overnight, but with the battery inside the morning battery is dead). Otherwise in "normal use" is empty in 2-3 hours.

[Q] Can my phone be fixed?

Have been using dual boot (wp 6.5 & Android) for 5-6 months. Android stopped working from sd card. Decided to try wp 7. Installed LEO70_ROM, got product key from Microsoft for Windows Live, downloaded and installed Zune. Everything was great. Got message to upgrade. Thought nodo or mango would be better. Now I have no phone. I tried unsuccessfully to go back to wp 6.5, to upgrade. Yes I know I screw up, yes it's my fault, but it has been fun learning new things and it will probably cost me something in the end. Here is where I'm at and what I've tried.
1)Power on w/o sd card-Get triangle w/ Software update failed. Please try again.
2)Power on w/empty formatted sd card-above for 1 sec then jumps to bootloader with: HX-B3; SPL-3.03.0000 XE; MicroP(LED) 0x05; MicroP(TOUCH) 0x40 displayed.
3)Power on w/vol down-opens bootloader. Same as #2 w/RUUNBH in upper right and PB81120 before HX-B3; Upgrade ROM code error; please try again, Serial.
Microsoft Device Manager does not recognize phone, hard reset acts same as #2 above, errors out when I try to run HSPL or custom radio. Reformatted sd card (not sure about partitions-created primary). I would appreciate any help. Thks

have you tried to flash stock WinMO 6.5 rom from SD card?
download stock rom for your HD2
extract *.nbh file from exe and copy it on SD card, naming it LEOIMG.nbh
boot while hold vol down..
if this fails, i have no other options on my mind...
if it works, it overwrites everything.. so you ought to have stock WM6.5 and then you can go flashing again

Have you tried:
1 - take the battery out for a minute
2 - power the phone on, holding down the volume down button to boot into bootloader
3 - flash a stock 6.5 ROM
If this works, then you'll need
1 - to flash a .50 radio (2.12.50 etc...)
2 - flash magldr 1.13
3 - flash the backto the future WP7 rom by XboxMod and Yuki. The LEO70 ROM is the original WP7 ROM from DFT and isn't updateable via Zune

Thanks for the info. I tried to flash 'T-Mobile_HD2_MR_Software_3.14.531.1' but I think I need an earlier version. The only one I could find was a .exe file. Do you have a link to the correct one?

if this is the right file for your HD2, then open it with WinRAR or 7-zip. Inside you'll see NBH file. Then follow what o wrote
and, make sure that this is corret rom file for your HD2.

Thanks, Yes it it the correct rom. I downloaded it from Tmobile support. Called HTC to see if there was a different rom and they said that was the only one they had available. To fix it they said I would have to replace the motherboard and flash the rom. When I try flashing the rom I get a white screen with 'Loading...' . Nothing happens then.

Use task 29 to clear everything, guide here http://forum.xda-developers.com/showthread.php?t=644781 then go to HTC official site and under support search for upgrades and download the latest rom for your phone and flash it.
Good luck.

I tried to run Task29 but I got a bunch of errors. I think it is because Device Manager does not reconize my phone. Can I copy the RUU_signed.nbh file from the extracted .exe file to the sd card and run it from the boot loader? Does the file need to be renamed? Is there another file I can run from the sd card? Sorry for all the questions.
Thanks for the ideas.

Are you sure you have the correct rom?
In case it doesn’t have Windows Mobile installed or you can’t get ActiveSync to recognize it, put it into bootloader mode: A.Power off your HTC HD2.
B.Press the Volume-Down button on your phone, keep it pressed and press the Power button.
C.Keep both the buttons pressed until you see the red, green, blue and white bootloader screen and then release both buttons.
2.Now connect your phone to your PC via USB. If this is the first time you’re connecting your phone to the PC in bootloader mode, wait for the drivers to be installed automatically. The term ‘Serial’ in the white area of the screen should now change to ‘USB’.

huh, i fear it's bricked. Sorry..

I would like to thank both of you for your input. Yes, that is how I put it into the bootloader. I also think the phone is bricked. I have read where you can have your phone unbricked. What do you think about sending it to someone to have it done?
Thanks again for your comments.

ITS NOT BRICKED I CAN BET ON THIS
Even I had the same problem ,I downloaded the official t-mobile update exe, but since I have been using HTC phones rite from Imate jam to kjam to jasjam to diamond to topaz till Leo so I found easily how to go back to 6.5 and also done for few local people, what I did is
1 Extract the tmobile update exe (see for the version which has ver. 3.03.0000 , u can find it on www.shippedroms.com or google it ) then using winrar extrect its content on your pc and rename the file RUU_Signed.nbh to leoimg.nbh
2 copied this file to my storage card and (fast use I keep a 2gb sd card and formatted &place the leoimg.nbh file to root of sd card so it looks like only 1file in storage card &no folders or anything)
3 turn off the device put the sd card & keep pressing volume down button and press power button to turn it on this will take u to 3 colored screen for a few second and then who loading on while screen if u have a proper matching leoimg on sd card then it will show u the contents i.e.
Radio v2
Splash
Bootloader
configdata
Os
And a few more things
now press the power button once and u can see the progress bar may be it mite restart ur phone but don't thing it screwed it will resume the update process & u will be back to ur stock rom
1 important point for u is that download the rom version 3.03 as it seems to me that u already have a stock spl and if u put un compatable rom then it won't move ahead from loading
Hope it helps u

[Q] hd2 not booting and usb socket broken

Hi
My HD2 is not booting up. It just gets into a loop showing the materializing/de-materializing android symbol.
I have done both soft and hard resets, but cannot get it to boot. My other problem is that the USB socket is broken so I cannot connect it to a PC.
I am using an external battery charger to charge the battery and then having to insert the battery back into the HD2. The booting problem started when the battery ran out of power overnight while in the phone.
I have android aMAGDLR V1.13 build feb 1 2011 by Cotulla 2011. On the hard reset RGB screen it displays
PB81100 HX-BC
SPL-2.08.HSPL 8G XE
0x05
CotullaHSPL 0X30
Then in the bottom white stripe it displays the word 'Serial'.
How can I get my phone to boot and then without the USB connection put the original windows 6.5 ROM back on so I can send it back to T mobile for repair as its still under warranty?
The other option is how can any trace of the android rom be wiped from the HD2 so I can send it for repair? I would just have to act stupid and blame the broken USB for wiping any ROM LOL.
I hope somone can help.

To return your phone to stock (including spl) -
1. Format your SD card using the format tool ON YOUR PHONE.
2. Download the correct firmware from your device from HTC official website
3. Open the .exe with winzip/winrar/7zip
4. Extract the RUU_Signed.nbh file
5. Rename the RUU_Signed.nbh file to LEOIMG.nbh (apparently caps is required)
6. Copy LEOIMG.nbh to the root of your SD card
7. Insert SD card into phone.
8. Boot into tri-colour bootloader (Hold vol down, tap power button but continue to hold vol down)
9. Release vol down when you see 'Searching...' on screen.
Your phone should boot to bootloader, notice theres a leoimg.nbh file on your SD card and flash the stock firmware you got from HTC. All data will be lost, as well as HSPL. You can then send your phone back for repair.
If this works for you please press the thanks button, its what keeps me lurking in the forums trying to help when I can =]

Thanks for the reply jwchips.
I cannot do step 1 as the phone will not boot so I cannot format the sd card using the phone.
I have the following original firmware from my phone- RUU_Leo_S_TMO_UK_3.14.110.1_Radio_15.42.50.11U_2.15.50.14_LEO_S_Ship
Do I rename this file to 'LEOIMG.nbh' ?
How do I save this to ' root of my SD card' as apposed to copy and pasting into my sd card?
What if in step 9 'searching' does not appear? As in RGB so far nothing happens. I'm charging the battery and when fully charged will follow you instructions and hopefully I can save my phone and send it off for repair.

Can you boot to MAGLDR? Is there a format SD option in there? I'm a clk user so I'm not 100% sure what options MAGLDR has. If you cannot format via your phone try to format via windows (try fat32 first, if it fails to flash try fat. Theres conflicting arguements as to which one works, but you can't cause damage by formatting to the wrong type, the flash will simply fail at the end).
The RUU_Leo_S_blahblah sounds like the install file you downloaded from the htc website. Rename it from .exe to .zip, open with winzip/winrar/7zip and look for RUU_Signed.nbh. Rename that file to LEOIMG.nbh.
The root of your sd card means not in any folder. So sdcard/LEOIMG.nbh is ok, sdcard/firmware/LEOIMG.nbh is not.
If nothing happens... nothing happens. Worst case scenario is you've wasted some time. The only time where things can go wrong is when you are actually flashing the firmware, and flashing via sd card is the safest way to go (no accidently pulling out cables/powercuts etc).
You won't see 'Searching...' unless the bootloader has found the LOEIMG.nbh file. As you don't have it on your SD card yet, you won't see it
P.S. Theres a thanks button now you know

jwchips, its updating at the momment. Yippeee. Will keep you updated.

jwchips, it has successfully updated. The screen shows the following:-
LEOIMG.nbh - OK
RADIO_V2 - OK
RCUST - OK
BOOTLOADER - OK
SPLASH1 - OK
OS - OK
CONFIGDATA --OK
RUU_WALLPAPER1 - OK
RUU_WALLPAPER2 - OK
Update Complete
UPDATE SUCCESS
Thank you jwchips. I've got the phone working with the original (rubbish)winmo 6.5 installed. Now I will be taking it to the nearest T Mobile shop so it can be sent to be repaired before my warranty runs out. Then I will be getting either the HTC Titan or and most likely the Samsung Note.

Glad to hear everything went okay!

Struggling to downgrade WP7, Please help!!!

I'm trying reinstall WM6.5 on my HTC HD2 from MAGLDR V1.13.

what am i? doing wrong, its driving me mad..
SPL version is SPL-2.08.0000

Make sure you’ve got more than 50% power on the device.
• Unplug USB cable
• Power Off device.
• Press and hold volume down button and press power button to start again.
• You will be presented with a tricolor splash screen.
• Connect USB cable to PC
• On the Tricolor splash screen you see “serial”; change to “usb”, if not unplug and plug the cable back in.
• As Administrator Run the WM6.5 ROM Update and follow instructions, your device should now be flashed with WM6.5.

after the radio, I cannot download magdlr, it stops at 29%.. Or sometimes doesn't do anything!!

I'd suggest task 29 to wipe the phone completly. Then make sure you have the correct stock rom for your phone. EG if you bought a EURO o2 HD2 then you need to have the o2 3.14 stock rom. Extract the .nbh file from the .exe.
Use SD Formatter to format your SD card, this will wipe all windows 7 partitions.
Then copy .nbh file and place it on the sd card, then boot into boot loader (tri colour screen) and follow on screen instructions. A grey screen should appear at this point.
This will remove Hard spl and restore WM 6.5 and also restore the first of the two splash screens and the radio back to factory settings and will also restore your warrently as well.

No but it is all over XDA. I think you'll find it someware on the WM 6.5 thread. If that doesn't work your nand will be stuffed but it has allways worked for me!

Sounds like nand is dead. Looks as if you will have to return it to get it fixed!

i must agree with ghost ... sounds like you flashed the poor baby to death :'( sad sad day! and very rare i might add!

cannot believe i messed it up.......

know where i can send it for repair? will HTC cover it under warranty? will they be suspicious?

anyone? do i need to ring my phone contract people or go directly to HTC?
Thanks

Depends how old it is. It may need to go directly to HTC to get it fixed.

I read somewhere that error [290]: Invalid Command - the ROM Update Utility has encountered communication errors during the update process.
Try changing the usb cable/connect directly to usb port (not usb hub) if you still want to use usb for flashing.
I always use the sdcard method when there's a problem flashing via usb. Rename RUU_signed.nbh (extract from stock rom exe package) to LEOIMG.nbh and copy the file to sdcard (sdcard MUST be formatted as FAT32 - use HP format tool). Put sdcard into the phone and boot into bootloader mode ... see if it works ...
