[Q] Have I bricked my HD2?

I was trying to follow these instructions:
http://forum.xda-developers.com/showthread.php?t=893948
I got as far as installing MAGLDR. When the phone restarted itself, it will not go passed the O2 welcome screen.
A hard reset (VolUp + VolDown + power) doesn't work.
If I hold vol down while I power it up it goes to the Red,Green,Blue,White screen where it says:
PB81100 HX-BC
SPL-2.08.HSPL 8G XE
0x05
CotullaHSPL 0x30
Can someone please advise me what, if anything I can do to get my phone working again?
Thanks.

no u are not bricked just reflash magdlr when its in the tri color screen vol down + power next time post in questions forums

Turn off phone by taking out battery and put it in
Then hold down vol down and then press off/end call button
should take you to coloured screen then connect to computer and it should say usb at bottom
then download the htc hd2 software off the htc site then flash the original software and should be back to normal

every nand build i test i do the following...
1. task 29
1b. flash radio
2. magldr
3. nand build

Are you holding end button while booting? that'll take you to magldr menu.
if it doesn't, then don't fear yet, cuz it's not bricked. Bircked is when you can't even turn it on, or it doesn't boot, or something like that. You can't even enter the rainbow screen when it's bricked.

It's cool that you're trying to help but this is how people brick their phones. It's obvious, from him posting on here, that he's panicking. He'll go to htc site and just download any official rom and if he has a tmousa hd2 he's bricked it now. Not saying he does but you have to be specific with people around here. You'd be surprise how many complete newbs are on here who Just refuse to bother searching and reading

listen just download a official rom from hd rom development
and then extract the file with 7z or winrar
you will see a nbh file
change it to as follows leoimg.nbh
place it on any empty micro sd card and insert it into the phone
and then restart with holding vol down
after the tricolor screen you will see a grey screen with options for updating your rom
just follow the instructions and you will install a new wm6 rom
after that follow the video and the instructions for the noobs on the hd2 nand rom development section ,download the video and follow it as it says you will be fine.
i have been through this and this is what i did and i am with gauners hd nand version on my hd2 running perfectly

It's used to clean NAND of leftover from previous ROMs.

There are a few methods to fix your problem actually,
Restore back to Factory Default with Official HTC firmware
Download Official HTC HD2 O2 firmware
Extract RUU_signed.nbh from the EXE file using 7-zip
Rename RUU_signed.nbh to leoimg.nbh and copy to the root directory of SD Card that is formatted in FAT16 or FAT32 and insert it into device
Power off your device
Hold onto the Volume Down Button and Power up the device
The bootloader will auto detect the leoimg.nbh file, and will start restoring back to default. This will restore your SPL, RADIO and FIRMWARE.
RED/GREEN/BLUE method
Power down the device
Hold Volume Down button and Power up the device
You will then see the RED/GREEN/BLUE screen
Connect the device via USB to your Computer
Wait for RED/GREEN/BLUE screen to show USB on the bottom instead of SERIAL
Run RADIO Upgrade (MAKE SURE YOU HAVE 2.10.50 and ABOVE)
I am GUESSING, your RADIO version is incorrect, causing it to loop.
You must use HSPL 2.08
You must use RADIO version that supports 576mb of RAM
Radio Thread
Incidentally, you can also reflash the firmware to any WINMO custom or official firmware while in RED/GREEN/BLUE screen as long as the bottom says USB and the device is really connected to the computer via USB. It might overwrite MAGLDR, and it might boot back into the official or custom firmware.
xcesivemastub8ah, both method works, again, help is "FREELY" provided to people who are willing to take the advise. People need to understand, if they tinker with something, they can and will tinker it to death. If you don't want to brick it, don't mess with it, use it as intended by the manufacturers, stock original.

No bootloader !!!!

I tried these two methods.
And what can i do if i can't enter in bootloader mode : it only reboot on bios (i think it is) and magldr.
I can't have a hard reset neither.
Radio : 2.15.5014
Hspl : 2.08

Fixed. Thanks for the help
Thank you all very much for the help and advice.
I did what was suggested and plugged it in while on tri colour screen, flashed the rom and phone is perfect again.
Your help is very much appreciated.
Next time I'll post in the questions section.

Help needed pls - trouble re installing winmo

Hi All,
flashed the dft nand rom two nights ago - Android 2.2 is good but it's not all it's
cracked up to be.
ok so here's my problem - nand is running well on my telstra hd2 but every time in connect it to the computer i get an error with usb tethering (device driver software not successfully installed) also get and error with htc sync option (i've downloaded the latest sync software from htc but when i run that it say's can't find phone.
charge only and disk drive options seems to work ok.
can i re install/flash winmo from disk drive option as i can't get an active sink.
does anyone else have this problem and if so how did you get around it.
i'm running vista ultimate at home and had same probs at work with xp.
any help would be greatly appreciated.
rob

here is a driver for xp
if you want to back win mo then you flash win ROM by entering boot loader not required active sync. to enter boot loader manually power of device then press volume down button + power button after this boot screen(three color screen) will appear. now run ruu and flash your device with win rom

error 202 - boot loader screen
thanks for advise pvkanjiyani,
can get to boot loader screen no probs but every time i try to flash i keep getting an error 202 message - this happens both at work (xp) and home (vista)
i'm tring to flash stock telstra rom from htc site - is this the problem?
does anyone know?
thanks in advance
rob

check the data cable is good condition or try another data cable
which boot loader do you have

i don't think it's the data cable as i have 2 - 1 at home and 1 at work
is the boot loader info in the red section of the boot loader screen - if so it reads
pb81110 hx-bcspl-2.08.0000 8g xe
microP(led) 0x05
microP(touch) 0x30
thanks

Well, I would download an official HTC ROM from HTC's website.
I recommend a v1.xx or v2.xx, then extract the RUU_signed.nbh from the EXE file using 7-zip or something similiar.
Then rename the RUU_signed.nbh to leoimg.nbh, and copy it to a MicroSD card that is formatted in either FAT16 or FAT32.
Turn off the phone, hold the volume down button, then turn it back on.
This will WIPE EVERYTHING, including SPL, RADIO, and FIRMWARE.

right now i'm willing to try anything - have just downloaded the latest htc teletra rom and also 7-zip
do i need to format my sd card or can i just copy to card as is and reboot?
thanks
rob

still having troubles
Hi All,
i followed LiFE1688 advise to the letter but hit a glitch - when i restarted the phone while holding vol down button a white screen comes up with loading...
on it and it just sits there doing nothing.
can someone please advise if the sd card needs to be formatted clean with just the leoimg.nbh file on it.
or is it that i downloaded and copied the file with vista os and my sd is formatted to fat32
or if anyone knows of any other way it would be muchly appreciated.
thanks

[Q] stuck in bootloader

Warning absolute noob here.
My HD2 leo froze in bootloader after using HD2Android NAND Toolkit.
Screen reads:
PB81120 SS-B3

CotullaHSPL 0x50
Computer won't recognize the device anymore.
Next steps to take would be EXTREMELY appreciated.

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.

Not working, any other solution

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] HELP ASAP!!! Software Update Failed and won't read SD Card:(((:((

Before I succesfully flashed Custom Windows Rom and had Android in my SD card root folder. I also flashed HSPL and MAGLDR113 and CWM Recovery v3.2 trying to install Nexus. But I couldn't copy the Nexus...rar file cause I didn't locate the file on the computer.
So I decided to flash back to original ROM for my HD2.
I copied LEOIMG.nbh to SD card but then it said "File cannot be located" so basically it partially copied and when I rebooted my phone and it showed white screen with a message of an update. I cancelled update but nothing happened it just came back to the same message and tried to update software but it failed.
So now I stuck in tri-color bootloader with a message:
SS-B3
SPL-2.10.0000 8G XE
MicroP(LED) 0x05
MicroP(Touch) 0x40
I doesn't even read the card any more so I CANT DO ANYTHING!!
What's weird too when I checked SPL version it was 2.08 but now it's 2.10.
WTF is going on? Can anybody tell me? Is it fixable at all?(((

Ok this is what I would do, I would back up my SD card on my computer. Then I would do a full reformat of my SD card with Fat 32. then re download the Windows Mobile stock ROM for your HD2 and copy it to the re formatted SD card. I would only have the ROM on my SD card and then put it in my HD2 and boot it up into bootloader.
The ROM you tried to flash is what changed your SPL to 2.10.0000. Cause the SPL flashes before the ROM does. So that means it was something wrong with the ROM and it could not flash it.

Yeeeeaaaaayyyy!
I fixed it, man!
What I've missed is to launch bootloader pressing down button, then it showed USB mode at the bottom, after that I could flash stock ROM to my HD2!!!
Now it's all good.
The only thing I wonder now: what HSPL should I flash?
Is HSPL 2.08 still ok?

You must have flashed a official update for your HD2 so I would say yes cause you are still on official stock software. But I still suggest you do a little double checking to see that the ROM you have is a ROm that was released for your specific HD2.

Yep, I don't remember what link I used but I put in my IMEI so it referred me to a particular rom!
Back on track now testing some new ROMs.
Do u have any suggestions for Android ROMs?

Hello to you all,
I have some sort of the same problem. First my original windows 6.5 did not start up any more. That made me look on the internet to see what options there where to fix it. After finding a lot of options I choosed to install android on my system. That worked for a long time but unfortunately it also hung itself up. As a reaction I tried a hard reset and it looks like that was fatal for my phone because I cannot install anything anymore. The only thing I can come in is bootloader menu but when I want to install anything, it stops before finishing.
Is there someone who can help me with this problem? By forehand thanks!
Kind regards,
Jaimy

[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.

Have you tried task29?
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.

Technology is great and thanks to everyone that helps the noobee's like me. Hope I can help in the future. You can't learn if you don't make mistakes.

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
