[Q] I seriously can't get into bootloader anymore..

Hi,
I want to change my custom rom, but for whatever reason I can't get into bootloader...
I can get into usb mode with ease... But not into bootloader.
pressing the + volume and - volume at the same time and pressing/holding the power button just makes my Titan go into a loop...
If I keep hold of both the powerbuttons but only press the powerbutton once, then the Titan just starts up.
What am I doing wrong here?
Come on guys, help me out here.
What you have to do is hold + and - volume button and shortly press power button. Do not keep pushing power button because that is what causes the continuous loop. Keep pressing the volume buttons until the bootloader screen appears and then connect you usb-cable.

Thanks, but I doesn't work for me...
If I press the power shortly, it will just start up...
It's like the volume up doesn't respond, although it does when the phone is on...
I say that because pressing the camera button and volume down does work, and gets me into USB Mode

Have no idea what went wrong with your phone. But I would try to flash HSPL again (with SPL goldcard) and if that does not work - I would try to flash stock (also with goldcard). But if the bootloader is somehow really damaged (somehow physically) - then you lose the ability to flash customs in future.
For now you are able to do it at least via goldcard.

Getting into download mode can be tricky. First, power off the tablet.
Then, hold the volume down button down - that's the volume button closest to the power button.
While holding volume down, hold power. When you see the samsung logo, release JUST the power button.
Apparently some models of the GTAB have the volume buttons reversed, but for the 7510 it's volume down.

Thanks for trying to help, but it didn't work. Continue with the problem of not able to put the tablet in download mode and I have problem in recovery, when I select to enter the recovery screen goes from top to bottom and I can not show the options.
