[Q] White screen and frozen buttons after downgrade - General Questions and Answers

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

[Q] No Recovery after Root

I just used the Universal Root v4 Live CD for my TF, but I do not have any recovery abilities. If i hold up and power when I turn it on, it just turns the screen black. Nothing else happens. I do have root. I have checked it with many different programs. Any Advice? Thanks in advance

In the 1st post of the thread there'a a FAQ:
[Q] How can I reboot in APX/recovery mode?
[A] Do as follows:
VOL UP + POWER BUTTON for ~5sec = boot in APX mode. The screen will stay black as if it is turned off. This mode is used only when you use nvflash to flash boot/recovery/data partition (this is the first step in my script).
VOL DOWN + POWER BUTTON ~5sec = will appear a screen where it says to press vol down again to wipe all data (obviously you don't want to do it now), or press up to enter RCK (recovery mode). If you installed CWM you will see the main menu navigable with vol up / vol down / power button.
If you have the stock recovery you will see a green android with a esclamation mark on a yellow triangle.
[Q] Help! I can't reboot in recovery mode!
[A] I think the main problem here is that it is a bit tricky to get into CWM recovery, once you see the small text come up don't try to read anything, just hit volume up.
Hold volume down plus power until the text in upper left shows,if you let go too early it just boots up and you never see the text. If you wait too long you don't get the option to boot into recovery. Hope that helps..

[Q] Samsung Galaxy S2 i727 ICS Root

I've recently upgraded to ICS, and am now trying to root my newly upgraded SGS2 phone. I am stuck trying to enter the Recovery Mode. I've searched online for guides on how to root, and many individuals instruct to hold the Volume Up + Volume Down + Power button, then when the SAMSUNG logo appears, let go of the Power Button. The recovery mode menu does not appear. Can anyone help?
Have you entered download mode and flashed the custom recovery through Odin? All this info can easily be found in the all in one guide that is stickied at the top.
More info is needed. How did you upgrade? Was it a one click method?
Edit for link: http://forum.xda-developers.com/showthread.php?t=1427268
Here is your link for the instructional thread. Please read this carefully. Everything you need will be on the first page. Any reason why you wish to root? Only reason I ask is because you are a new user.

Regardless of which recovery you have it has to come up.
Turn the phone off, now hold all three vol up/down and power once phone vibrates let go off power, don't wait for the logo

[Completed] Dead Android (Nexus 4)

So I tried to get stock Android back to my phone (I had cyanogenmod) and when following the instructions of a guide I found, they said there was a possibility of getting into a boot loop, which indeed happened. To solve this I had to go into Recovery Mode and the logo of DEAD ANDROID would appear, and so it did. The problem comes when I push the power button and both volume buttons to get into the menu of recovery mode. It doesn't come up, the phone just shuts down.
I don't know how to solve this or if it even has a solution... could someone please help me
Ps: yes, I'm a complete noob :good:
Hi, thank you for using XDA Assist. To get into recovery when you see the dead Android press and hold the power button and then press and release the vol down button. It can be a little tricky, especially the timing of the press and release of the vol down button.

Not sure if this is the proper section for this but thought I would post this here as I'm sure it would highly assist people in development and other tasks. This is the button combinations you need to enter each mode.
ODIN/Download Mode
Make sure your device is completely off
Key Combos: Volume Down + Home
While holding both of them simultaneously press the Power button until you see a disclaimer on the screen
Then let go of all the buttons and press Volume Up to accept the disclaimer
Once the green robot is visible on the screen this indicates that handset is in now ODIN/Download mode
Recovery Mode
Make sure your device is completely off
Key Combos: Volume Up + Home
While holding both of them simultaneously press the Power button
As soon as the phone vibrates, let go of the Power button but keep holding Volume Up + Home
When you see the "Samsung Galaxy S III" logo (not just the word "Samsung"), right after that, the next screen you should see is your recovery
Don't let go of Volume Up + Home until you see your recovery

As long as the phone is NOT connected to a computer, that is you are not downloading anything, you can simply turn it off by holding the power button. Another option would be to pull the battery.
