hello guys..i'm a newbie in android, and, i have a big problem now. i tried to install another rom instead of the stock one (spanish), and now my device doesn't start at all. i tried many ways, and each time i was able to go to fastboot menu or recovery menu. now, after i've done some steps from this tutorial: http://forum.xda-developers.com/showthread.php?t=491350&highlight=model+incorrect , my device keep restarting by himself. I cannot reach even recovery menu or fastboot menu. It starts the logo screen for 4-5 seconds, and after that is restarting and again the logo, even if i'm trying to press home+power or camera+power. what can i do???
My problem is like in this movie
if i press action button + power, nothing happends on the screen, but the blue led in the right top corners stays powered on. Do you know why?
If you cannot get in to recovery (home + power) or the SPL (power + camera) then you're doomed.
not even with jtag or something, cannot be done?
Unless you physically replace the motherboard (which doesn't look too hard) then no you can't. As of yet there's no Jtag method.
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...

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.
Hello,
I wanted to ask if someone clashed with problem like that and knows how to solve it. I had 1.66 rom eastern euope and installed 2.08hspl, tried to install latest magldr and I am guessing problem occured because I didnt installed latest radio. Now when I am turning on the phone it shows white screen and green logo and stuck. Tried turning of the phone and holding - volume button when turning on that didnt make any difference can someone help me to revive my phone ?
So you tried to get into bootloader, but the thing is you have to try harder.
Bootloader should work just fine.
So again, turn of your phone. while the phone is turned off, keep the vol down, and press the power button.Release the power button, but keep the vol down pressed.
You can try the other way: hold the vol down pressed and reset the phone(red button on the back).
If you want to use the SD card method to flash something you still have to enter the bootloader, so you must keep trying.
Forgot to ask: did you manage to enter the bootloader or not, cause you only said it did not make any difference????.What does that mean?
I already trying to enter bootloader for the five hours, so I guess it's impossible, also tried that thing with red button it didnt load up that bootloader screen. The thing is that holding volume key down didn't work for me before to get into bootloader even when the phone was ok but it did install all roms which I tried so I didnt think that this would be problem either apparantely it is... Maybe youu have some other suggestions how to fix it ?
If you can make the pc recognize the HD2 then you can flash anything.
But i think that this is only possible in bootloader or windows or android.
So this is a problem.
No ideea for now.
Anyone help???
But you *do* push both vol. down and power buttons and keep them pushed until the screen turns on, don´t you?
I didn´t get into the bootloader as long as I didn´t kept both buttons pushed long enough... had to learn the "timing" kind of...
Question for wizards:
Is there any way to enter boot loader without volume keys?
Keys are defective.
Phone is stacked in windows screen and can not boot completely to use ActiveSync.
anyone please ?
search for this program''quick shutdown'' on this forum...it has the option to restart in boot mode
thanks for reply!
Problem is I can't access windows in my touch2. It is stacked in boot process.
Do you have any other suggestion? Some key sequence, other than vol down + pwr ?
this was my problem too. my volume buttons are not working. when i diassable my phone, volume buttons are cut from the board. so when the phone stucked at boot or something, i have to diassamble the phone then use right combination for volume button down(over the board, using a cable or something metal) + press end call button. then i can see bootloader.
