Hi,
I installed Android (Donut) on NAND on my HTC Polaris.
Now I would like to flash a NBH with a more recent version.
But I can't access to bootloader (screen with different colors) reseting the Polaris with holding the "camera" button. I can only access the install menu of Android (holding "power button")
How can I retrieve the screen with different colors ? Or can I flash a new NBH with an other solution ?
Thank you for your help.

Remove battery
Hi
Please do a search in the future for your question. Your answer is over here:
For your convenience i will paste it over here:
•To flash your device you might have to put your Polaris in bootloader mode. To enter this mode you have to do the following:
•Press and hold the camera button.
•Press reset while you hold the camera button. Release it (the reset button).
•Hold the camera button until de colored bars screen appears.
•If it doesn't work, remove the battery, wait for some seconds, put it back and try again.
•When the colored screen (Hard SPL) is shown, you are ready to flash it using the flashing application (CustomRUU.exe, for example).
1. Power off your device
2. Press and hold camera button
3. Press power button
4. Use CustomRUU.exe for flash device
Go Go Go!!!
Bootloader
1. Remove battery
2. Replace battery
3. Press and hold camera button
4. Press power button
Procedure works just in time.
With no success, start with 1. again.

Try to (exactly)
IF THE PHONE IS POWERED ON
1: remove the battery
2: keep BACK pressed while reinserting the battery (KEEPING BACK PRESSED)
3: wait some seconds (KEEP the keys pressed)
4: the phone should be in fastboot mode
IF THE PHONE IS POWERED OFF
1: press BACK, keep it pressed, press POWER, keep it pressed
2: wait some seconds (KEEP the keys pressed)
3: the phone should be in fastboot mode
If this is not working for you, maybe you flashed another SPL and/or another radio.
I've written a lot of posts recommending not to change the SPL because it seems 1.33.1008 or 1.33.1009 are the latest (at the time of writing) like the corresponding radios.
I don't have any image for this SPL or radio version and I don't know a method to recover from a bad SPL.
I hope your problem is not a hardware or SPL related and you'll be able to get fastboot mode.

I was trying out a new setup on my phone when it got stuck on the Motorola M. I found that you can boot into System Recovery with out going through the app and doing a recovery boot. This is not the factory manual reboot procedure.
***Boot into System Recovery**
Steps
1. If stuck in M logo screen or Dexter's screen, pull battery
2. Insert battery and hit power button
3. As soon as you hit power button hold the Volume up button down until the unboxing logo comes up.
**Updated with info provided by 3rdstring**
And now you can use nandroid to go back to a earlier version of dexter's or what ever you have on your card.
I would also recommend to wipe the dalvik cache, and cache partition. You do not need to do a factory reset.
Hope this helps others out, no need to reflash to stock version when your phone bricks.
**Factory Reboot steps***
To Manually Reset
If there are significant problems with your device or you are not able to follow the steps above please use the following process to manually reset the phone:
Turn off phone
Press Power key + Camera Key + GalleryKey to power on the phone and bring up the recovery screen
When the Triangle/Exclamation point screen appears, press Volume Up + Gallery Key down and tap the camera key to show the recovery menu.
When the recovery window appears, use the volume up/down keys to navigate the menu and the camera key to enter your selection.
Select Wipe data/factory reset
Select Reboot Phone
You should only need to hold in the volume up button while powering on the phone to boot into OpenRecovery once it's installed either via Dexter's System Recovery app or through the directions on ModMyMobile.

I do believe that is what I said. Tested it myself. Hold the power button to turn on like normal, then just hold the volume up button down.

when you do a cold boot (hard reset) you have to
1. Power off the phone. Remove and re-insert the battery to make sure.
2. Press and hold the middle of the Volume button (so that both + and - are pushed down) and the Camera button. While holding these button also press the Power button.
3. Wait until the screen shows "Cold Boot" then release the Power button only.
4. Keep holding the middle of Volume and Camera buttons pressed until the Welcome screen appears.
This may require some fingering to get it right. If you don't get it right you may accidently enter the emergency download mode.
If this doesn't work you can use the download mode to deploy a NoDo rom that might be available for you phone.
Hi Mates,
I tried to root my HTC Desire HD - but something seem to have gone wrong?!
I downloaded the Advanced Ace Hack Kit and read the effen manual guide.
Then I started the "hack-ace.cmd" as Administrator on Windows 7 x64.
I entered the key from the txt file and proceeded with selecting 1 and pressed Enter key.
Then the program told me that I needed to downgrade, so I confirmed with "y" and then it asked if I wanted to download some UUR or what it was called, so I confirmed again with "y".
After some time it asked me to reboot, but after startup I only see a white screen now, with H-BOOT-0.85.0024 - Radio-26.09.04.12_M2 - bot my vol up and vol down keys + power button on the phone does not respond now... so I see BLUE highlighted HBOOT and FASTBOOT on my screen now, but I am not able to select with VOL DOWN to go to Recovery or any other menu items, af the VOL and POWER buttons are frozed.
If I remove the battery, then I am able to press and hold down VOL DOWN and POWER together, in order to enter this menu again... but no reaction after this.
What do I do to recover my phone now, as I wanted to root it, and after that flash it with a new file?!
Thanks in advance.
Kind regards

Hello, I have a big problem with rebooting to recovery mode. I can reboot to recovery only with application. If I turn my phone off and then hold volume up + power, then I get black screen with only one yellow Chinese text on the very top left side and then after 1 minute it's get into Chinese recovery.. My question is: how to get into custom recovery without using applications like for example "Quick boot".
I need it, because I have to install ROM again, because I did a big mistake, when I deleted one file from the "system" folder. Now my phone boot without problem, but after that everything is lagging and all applications stop working, then it automatically reboot phone..
I can't flash firmware with SP Flash Tool, because of Windows drivers. My laptop does not recognize the phone. It says: "Unknown USB device".. That's why I need to get into custom recovery for installing ROM.
Thank you in advance for help.
This helped:
With the phone powered off
Hold Volume Up + Volume Down + Power button
When phone vibrates release power button only.
As the No Comman Screen release all buttons.
Press and hold the power button and tap the Volume Up button.
Release the buttons. You must get into recovery mode.
