To perform a HTC HD2 Leo hard reset
1. With the phone turned off, press and hold the VOLUME UP and VOLUME DOWN buttons, then press the END/POWER button shortly and release it. You will then see a message on the screen telling you this will erase xxxxxxxx......
2. Release the VOLUME UP and VOLUME DOWN buttons.
3. Press the VOLUME UP button to perform the hard reset, or press any other button to cancel the reset.
Soft Reset
If i may add,
A soft reset,
1. Open the back with your thumb or finger
2. The RESET button is located below the bottom left slot for the battery and the SIM card. Use a small object with a blunt point like a toothpick to the RESET button.
3. Your phone will restart and the Home screen appears.
Correct me if im wrong,
Sorry im a newb, but what is the precise difference between hard and soft reset?
Will a soft reset delete stuff such as contacts, pictures and music? And will hard reset do the same?
thanks smaberg...
you should add the two other methods to the first post
there is the soft-reset button (little red button) and a software method (clear storage).

the "software" method (clear storage) is a hardreset, witch means you will restore it to factory default, deleting all info on phone...
the softreset only restarts the phone.
after flashing a new ROM i always recomend a hardreset afterwards, to be sure to get rid of all leftovers...
(Useful if flashing a rom and battery is less than 50%)
Enter bootloader mode:
Momentary press the red reset button on the back of the device, near the sd card slot, while holding the volume down button. Keep pressing on the Volume down till you see the bootloader screen. If you did not have volume down pressed as you were pressing on the reset button the device is just gonna reset and no change will take place.
Else, you will see "serial" written on the bottom middle of the screen if you're not connected to the PC via USB cable yet. "USB" will replace "Serial" when windows recognizes the device. Once on this state, you can press "next" on the rom installer where you have to acknowledge you connected the device via USB and your battery is grater than 50% and so on and so on.
You can start the installer on the PC prior to connecting the device in Bootloader mode. I don´t know what happens if you enter bootloader while connected to the PC (if you don't either, don't do it!!)
Note: I advise against using this mode with less than 10% or so. I guess you could end up with largest screened brick in the market.
To clarify previous posts:
Hard reset: Resets the device to factory defaults or to the last rom you installed.
How?
-Hardware method: combo of hardware buttons (described above)
-Software method: slide through HTC sence till "Settings" bar and select "Security" (top option). Then select "Factory resets" (last option). To my knowledge it does absolutely the same thing as the hardware method. correct me if I'm wrong.
Soft Reset: changes you made will take effect after the device resets (installed apps or reg edits...) OR you got to a sticky situation and you need to reset to get everything running smooth again (device shows abnormal operation of some kind).
How?
-Software method: Hold the power button till the quick list appears and press "power off" option on the top. You can also be presented with this option after installing some apps or after changing something within an app.
-Hardware method: remove the back cover and press the little red button near the sd card slot. Useful if the device stops responding and you are unable to soft reset by any other way.
Enter Bootloader Mode: allows for flashing devices in any battery state. It doesn't do anything by itself, just allows roms to be flashed. Some people have gotten stuck on this screen http://forum.xda-developers.com/showthread.php?t=599259, so use the search tool and read up before using. After flashing a rom you will loose every setting and file you had on the device itself. SD card will remain untouched (or so it should). I've read people advising to remove the card prior to flashing. Not exactly sure as to why. Files saved to the SD will remain intact. Apps installed on the SD card (aka. "Storage") will remain intact, only not registered or linked with shortcuts anymore. The device basically doesn´t know they exist.
How?
-Harware method: button combo (described above).
-Software method(ish): If you don't have to manually enter bootloader, the rom installer will take your device through this step without you having to do anything besides connecting through USB (activesynk, I guess) and running the RUU_LEO_xxx.exe file. You will see a progress bar on both PC and device as the rom is flashed.
Note: Reseting the device (turned on) while pressing a key (ex.: vol down) does the same thing as pressing the power button (with the device turned off) while pressing that same button (vol down).
Maybe you could transfer this info to the 1st post and clean up the thread a bit... Even, this could be at the Wiki section. Or better, a link on the Wiki to this thread
Hi guys,
I tried with both volume up and down pressed to hard reset, but not really successful. Perhaps I am doing something wrong?

did u press power while pressing vol up/down?
Well, for entering bootloader mode, you can do it in "software mode" without having a PC connected to your PPC.
You can just run EnterBootloader.exe from your device.
(see attachment)

yes, I did. But when pressing I do not feel that is actually "making contact" I tried several times...
I will try with the bootloader from above...let's see...
Thanks and regards,

If, for some reason, you cant hard reset using the power button, you can always press the reset button on the back of the device while pressing both vol up and down. After the vibration, it will enter the hard reset menu (remember to keep pressing both vol buttons till this point).
By the way: were you pressing the power button and both vol buttons with the device turned off? Cuz, with it turned on, you are just cycle through the quick list and vol menu like crazy.
Yep...pressing with phone off.
I tried with the reset button from the back of the phone and it worked.
Thanks guys...

Seba
hey,
i need to send my hd2 back for repair but unfortunately i can't get into the bootloader! volume up / down buttons do work when im in windows mobile, but when the phone is switched off, i press volume down + power button once and the phone just boots into windows mobile.
is there any other way to restore your phone to the stock spl?
You need to press Vol UP and PowerOn, not Vol Down

On my device it is PowerOn and VolDown. But I have to press and hold the VolDown button till the device is in bootloader mode.
Best regards

Taken from one of the many tutorials on here...
"*Go into BootLoader Mode (turn off phone, then press and hold the VOLUME DOWN then Press and hold the POWER button. After about 3 seconds the tri-coloured screen should appear)".
Do make sure you are pressing the volume down button hard enough AND for long enough.

tried it but still doesnt go into bootloader mode... i have managed to go into bootloader mode before (with several htc phones i have owned), but i think something is broken this time (my hardware sendbutton also is not working any more, that is the reason why i need to return the phone).

Try running the attached EnterBootloader.exe from your HD2 (unzip, move .exe to phone, run).

Sorry then, Vol UP has been my other phone I haven't flashed the HD2 via SD Card yet.
I just can think that you do not press the Vol DOWN button hard enough or long enough. You have to press and hold the Vol DOWN button and switch on the phone, then lift the power button while still holding the Vol DOWN button.

thank you, with this file it went into bootloader mode, but somehow my hardware-buttons seem to be broken (in win mobile all of them beside the send-button work), when it says "Press power buutton to start update image", I press the power button, but nothing happens!
I guess thats it, no chance to restore SPL and no chance for warranty any more .

Hmm, very weird.
The actual keys are obviously ok - they're just not handled while in bootloader. I'm not sure what exactly is responsible for that, I assume it's not the OS, so perhaps SPL or Radio?
Not sure if it would make any difference, but perhaps you can try reflashing the HSPL (or maybe a different radio?).

when its asking to install the rom (in bootloader) hold down volume up (or whatever key it asks you to press to install) REALLY HARD,
another suggestion, take off the back, the buttons seem easier to press when the back battery cover it off
maybe this will work
1. On the Home screen, slide to the Settings tab and then tap Security > Factory reset.
2. Enter “1234 ” and then tap Yes.
Ooops!
If your power button does not work it will be impossible to flash from SD card and this is the only way top reflash a stock rom = the only way to uninstall HSPL.
But if this is the power button, then how do you already power up your device ??? Is this your reason to send it to the repair?
You seem stuck in a button my friend...

it is a real wierd problem, i can switch the phone on with the power button and when it is turned on, all keys work beside the talk(send) button. but i can not go into bootloader mode and power button / volume down button to confirm / cancel update when entering bootloader mode with bootloader.exe don't work.
you should really try to reflash radio and hspl again. if you can power on the device the hardwarebutton must work. looks like a software problem...
have you check that you vol down button is working? it happen to me before,
maybe you could contact the hspl maker if he can help you? i have in my mind that he could "hack" the procedure to NOT ask for SEND key press?
Thanks for all your replies. I left the phone off for about 4 hours charging. I switched it on press the vol down button and it worked! How weird / lucky. So I flashed a new rom and I am working again.
Thank you so much for you time.
One last thing though, now in WinMo the vol up and vol down work and the power button work. But the other 4 hardware keys don't, they just force the phone into vibrate/silent mode. When I get a phone call it also turns the volume down/off/vibrate.
Maybe a hardware failure?

Hi Guys,
I'm in big troubles....
my Universal died after a radio upgrade....so I need to flash it again with another Rom.
The problem is that the power button is phisically...it's un-solded
That's the question: there's a way to enter in bootloader without pushing power button and without the possibility to execute something from the mobile phone?
I tried to HR (soft key + reset) I get the white screen, I push 0...then nothing!
BLACK SCREEN!!
HELP MEEEEEEEEEEEEEEEEE!
Read up on ABD using Android SDK.
You can push commands through to your phone
I have no volume controls so I know how you feel.
I'm trying to think back. Doesn't it switch to bootloader if you start to flash (when you have active sync connected).
Otherwise you may have to find the solder tags for the power button and short them to perform the switch to bootloader.
Hi all !
I can't enter the bootloader screen (screen with blue, green and red stripes) by pressing the volDown key after a soft reset. The phone simply boot on the rom and don't let me see the desired screen.
Is someone can help me to retrieve access to the bootloader screen ?
Radio 2.10.50.8
ROM EnergyRom GTX [13th may 2010]
it shuold be as simple as holding down vol key when powering it on...like you are doing.
u really shutted it fully down and powered on again? or just softreseted via software?
I have tested the two solutions ... I also turn off the device for one day and turn it on pressing the volDown key ... the result was the device booting normally !

mmh.. and if u want to hard reset ur phone? i mean.. when u press both, volume up and down at the start.. does atleast the hardreset screen appear?
No It change nothing ... I really can't access this screen anymore. I try also to upgrade to HSPL 2.X but the issue persists
Oo thats weird.. for what do u need the screen anyway?
i would flash a new rom maybe.. so the prob could be solved that way, but i really dont know if that will help >.<
try it with the battery cover off to get a better press
power off
press and hold and keep holding vol down
press and release power KEEP PRESSING VOL DOWN
only release vol once three colored screen shows.
samsamuel, I flash my HD2 more and more but since I test the radio 2.10.50.XX, the device just boot normaly and it not let me enter the bootloader screen (I keep the volDown key during booting after turn on the device like you said)
Darksorrow, I need to get back to radio 2.08.50 because the 2.10.50 sucks my battery very quickly ... :'( I'll try to flash the device with an other ROM ... with luck It could give me back the access to bootloader ...
the rom can't affect the bootloader in the same way that your installed operating system on your pc can't affect the bios.
even if you wipe the rom completely you can still enter bootloader.
anyway best of luck.
edit - in using same radio as you.

Thanks for the information and after flashing I understand that the bootloader still unavailable by pressing down the volume down button ... Is it possible that this was and hardware problem even if volume keys works well in Sense?

Its possible, but unlikely.
I dont mean to sound like i dont believe your results, but i cant help the feeling that you arent doing it right.
Every post so far where someone couldnt enter bootloader / start a hard reset has been down to the order of pressing and the length of the press.
Its usually that they are
1 - pressing and holding both power and vol
or
2 - releasing vol down when they release power
or
3 - not pressing vol hard enough (this is where the battery cover off helps, it allows the button to press more firmly.)
or
4 - pressing power before they press and hold vol.
all of which will fail to enter bootloader.
ill repeat the process, just for clarity.
power off the phone
press hold and keep holding 'vol down'
tap and release power BUT keep vol down pressed
release vol down when the three coloured screen appears.
any more than that i cant suggest, sorry.
Here you go. Give this a shot. Run the cab on your device and there will be a shortcut in your start menu to take you to bootloader
It works fine. Thank you.

Thanks a lot this work for me too !
@samsamuel : I understand the way you explain me Even if I kept the vol down touch after powering the device I just see the device booting on ROM ...
I have one more question, do you think I can perform a format (with MTTY) considering the fact that I can't access to bootloader at startup ? I hope this work but the risk is that I can't never install a ROM after formatting if I still can't access to bootloader by pressing volume down at startup ....
Thanks Zelender, the file works wonderfully. ...and yes, I'm sure I was using correct procedure to enter bootloader as I had done it before.
I have a similar situation, but I have a Nexus One. I know this is not the area for the N1, but this is the only place where someone is having the same issue of not being able to go to the bootloader. I press vol down while hitting power button. This would always give me the boot loader menu, but instead it just boots to the OS.
Any way I can regain access to the bootloader, because my os is messed up and my radio isnt operating.
Thanks
Hum ... I just process an task 29 via MTTY and the result is .... "phone sent for repair" so for those who have the problem, DO NOT EXECUTE TASK 29 or you'll have a blank phone and you'll can't install new ROM.
I can't return to winmo rom.

I've the same problem as Fl3ek : I flashed a nand android rom with magldr and I can't return to bootloader mode and I can't make a hard reset. The only thing working is magldr but only for flashing nand android roms (i tried 3 of them : they all work ).
Is there an APK like bootloader.cab ? Or a program to flash or activate bootloader in nand with magldr ?
I tried quick boot with bootloader option but it does'nt work.
need your help guys
My mates just got a galaxy s and hes locked the phone with the pattern unlock screen, theres no google account registered to the phone because its brand new so there is no other option than to keep trying with the pattern unlock!
Is there a way to factory reset the phone without flashing a new rom whilst in this situation?
If not, where can i find the correct stock rom (not interested in upgrading yet) and the correct version of odin?
Thanks Craig
you can boot it into recovery when you shut down the phone and then hold volume up, home and power until the samsung galaxy s i9000 screen appears. then release the buttons, you can navigate in the menu with the volume keys and confirm with home.
