[Q] GT-P7510 on Official ICS won't go into Download Mode (Help)

Hey there everyone.
I've been an short term Android user (almost a year now), and I've fell in love with the customization and the flexibility of the platform.I had only recently delved into rooting and ROM-ing on my GS2, which I bought about two months before purchasing the Galaxy Tab 10.1 When the GTab received the OTA, I noticed that ICS with the TouchWiz overlay is either somewhat smooth, or downright laggy. YouTube performance lagged Honeycomb, and that's saying something. Finally, I decided to root my GTab and install CM9/10. I went to the first source I saw (http://forum.xda-developers.com/showthread.php?t=1239185), and to my surprise, I was stuck on step two.
It won't go into download mode. I tried 5 times, each time trying in vain the right volume+power and all three. No luck. (Insert: WTF). Is there something wrong? Everytime I enter the volume down+power, it goes into the Galaxy Tab 10.1 Splash Screen (As it should), and then nothing else. Then it appears again. And then disappears. And Appears. In this infinite loop, with no two icons showing up. If I let go of the buttons, it boots up regularly.
What do you guys think of the problem? Software (Most likely, huh?), or hardware (buttons work flawlessly in use). If not, is there a alternative way to root the device without going into download mode?
Thanks in advance,
Andrew
Power Button and the Volume Down Button pictured here! With Tab completely turned off and the plug not connected hold the power button and the button directly next to it " The left volume button" for up to 10 sec!

[Q] Power button work around?

I have a HTC EVO 4G LTE that I use for controlling the chromecasts and for playing games. The phone is stock rooted S-OFF and has xposed installed. The power button has been giving me problems so I've remapped the camera button to turn the screen on and off. Since that only works once Android is booted it won't help me if the phone gets accidentally turned off or if the battery drains. Is there a way to have this phone boot when it's plugged into a charger like the Nexus 7 does?

Bluetooth Media Keys inactive when no media is playing

Hi, I'm having an issue here that when my bluetooth device is connected and no media is playing, all the bluetooth media keys (vol +, vol -, play/pause) would not be detected by Android. When I press volume up or down, the volume would not adjust when no media is playing, just in case I want to lower or raise the volume before media plays (Absolute Volume Control on). I had this issue for a very long time but now it has irritated me to try to find a solution to it. I have this issue with all of the devices listed below.
Is there an app/mod that could keep the bluetooth media keys active when it is connected? Thanks.
Tested with:
Earphones:
Sony WI-1000X
Samsung Level U Pro
Android Devices
Samsung Galaxy S7 Edge (Stock Oreo)
Samsung Galaxy Tab S2 (Lineage15.1, stock nougat)

Once screen go to sleep there is no way to wake it up

Good Evening
I own a Samsung Tab S2 (SM-T810) and I am running stock firmware (Android 7.0), rooted and TWRP as a custom recovery.
Yesterday i was using my tablet when the screen suddenly turn off, i tried to turn on the screen as i usually do, with my power button but it doesn't work, i connect the charger and the screen wont turn on (like usually do).
So i go to TWRP and i realize that every button was working in there, if the screen turn off i can wake up with power or home button like i normally do on the stock OS
The problem begins when the system (Android 7) initialize, the navigation bar + home button wont work from the beginning , the power button works only for turning off the screen but not to turn it on, the volume buttons work until the screen turns off
Once the screen is off there is no way to turn it on, neither power button, connecting it to the power, or notification, the only way is restarting the device by long pressing the power + volume down
I already do:
wipe Data, Cache and Dalvik from TWRP
Reflash my stock firmware with Odin
This is my first time posting a question on this site, if you need more information please let me know.
Thanks in advance
I just remove the Samsung cover from my tablet and it fixed the problem!
