what version ?
when the first time the screen show up, keep press-release the vol-down button
or
connect to pc, adb reboot recovery

Keycombo recovery on CM.
If it's CM, the keycombo of recovery are called by init.rc
Code:
service prb /sbin/prb
user root
disabled
oneshot
keycodes 114 116
Looking at qwerty.kl (default keyboard layout)
Code:
--- cut ---
key 115 VOLUME_UP WAKE
key 114 VOLUME_DOWN WAKE
key 116 POWER WAKE
key 212 CAMERA
So, the key combination = Vol Down + Power button
If there's bootloop, but those button combination not working, then service prb /sbin/prb aren't called yet, so it won't work. It might happen when the bootloader not initialized correctly..

?? you don't even indicate on wich rom you are...
If it's on stock rom without flasing any kernel, yes I want to know your secret.
Otherwise, no. I already know how to enter in recovery

Switch SD card and cant go to recovery anymore !

I managed to switch my sd card and now there is no option for boot into recovery anymore ! Please help me !!! When I tried to flash again via fastboot, it said that the image cant be loaded !
How are you trying to get to recovery. Volume - button and push the power button.
OP...you may want to be a bit more detailed.
Why and what are you flashing 'again' using fastboot?
huh!! very confusing post... what boot into recovery option... which ROM are u using and as @SiNJiN76 said... what are you trying to flash "again"???
well, I tried to press the power button and the trackball at the same time, but there is no option to go into recovery
Edit:
My bad guys, my mistake, i press the power and the trackball instead of the volume down button ! Sorry and please forgive my stupidity

I managed to switch from a 4GB class 6 to an 8GB one ! After that, I cant seem to boot into recovery anymore ! I tried to flash the recovery image again but it said that the image couldnt be loaded
Press Volume Down and hold it down while you press Power. Keep Volume Down button held 'til you get the white screen. You'll see recovery...press volume down to select it then power button to enter recovery.

When the volume keys to select the option "reboot system now" and press the power button nothing happens. Nothing happens even when I press the home button, which I did not ever worked. When I hold power button for 10 seconds the cell phone turned off, and when I hold a few seconds, the mobile restart and back into recovery mode.

if u guys just like to get the phone back to work, it would be the best to just flash a new ROM via ODIN. After that, the phone boots normally.
But I dont know if this is an option!
Hope u are still able to get the phone to downloadmode via 3-Button-Combo?!

Home button isn't working -> no 3 button combo
try using a jig to get it in download mode and flash a stock rom
In recovery mode, you also can boot system with power-button.

Bootloader problem

Hey, any1 might have a clue why i cant enter bootloader?
vol- + power equals normal start
im using deepshining 6.1 if it makes any difference

Using Deepshining myself since yesterday (v7 though) and I just tried what you said.
However I "think" I know your issue, if you try to press both at the same time (volume button down + power button) you might end up with just booting the device normally cause you hit the power button first.
Just try this: shut down the phone --> press & hold the Volume Down button --> press the power button. The phone should then just boot in bootloader (at least for me)
That's all I can think off but im no programmer. Hope it works!

Power your phone off, push and hold volume down, then hold power button as well and hold it for a few seconds. Then you ll reboot to recovery or simply boot the phone, hold the power button, choose reboot, in the next menu choose boot recovery and done.
Sent from my LG-P970 using xda app-developers app
Doesnt work for me, i need combo to get recovery without booting my system, because my CM10.1 is broken and wont boot..

doesnt work.
simple use SFT.
there is PBR (iirc, pseudo-boot recovery, button combo to enter recovery, cmiiw) on cm10. I think cm10.1 also has it.
turn on the phone, focus on led button, when it start blink for the first time press volume down + power button. You should press it at the right time to make it work. Tried it couples of time.
thank you, it works!
