What other apps? Like some reboot app? Maybe they send the wrong argument to the bootloader. Might not be compatible with our device.

If you can get in using hardware buttons, then its mostly a problem with the other apps you are trying.

Download terminal emulator, run:

Code:
Select Code
su
reboot recovery
and you're in recovery. If that doesn't work for some unknown reason, you need to switch roms.

EDIT: disregard this, per adams post below.

It doesn't work on stock rom unless you manually write recovery boot command to misc partition.

As Adam posted above, none of these apps/ commands will work if it isn't defined in the misc partition. I wasnt aware of this before Adam pointed it out, ill look into the easiest way for this to be done.

IIRC now that @GalaxyVolvoZ posted ROM Manager works, because it writes the needed command.
Otherwise this is the command needed in shell:
Code:
Select Code
echo "boot-recovery" | /system/bin/dd of=/dev/block/mmcblk0p5 bs=1 count=13

Thanks! slightly off topic, but do you know what format the misc partition is?
