Installing from recovery

did anybody manage to install anything in recovery, either sideload or from memory? My recovery always gives an error not being able to mount /misc (which seems fairly neccessary, given:

// Store a string value somewhere that future invocations of recovery
// can access it. This value is called the “stage” and can be used to
// drive packages that need to do reboots in the middle of
// installation and keep track of where they are in the multi-stage
// install.
// The first argument is the block device for the misc partition
// ("/misc" in the fstab), which is where this value is stored.

Sideload always gives a verification error, and installing from storage only lists a directory entry …/ I can’t find my zip file, even if put into the update directory

How did you get into the recovery?
Pressing “volume down” while switching on (like my HTC Desire HD) makes my phone freezing (have to battery cycle). Holding other keys has no effect.

Volume up is for recovery, Volume down for fastboot mode.

Or adb reboot recovery from running phone


I can’t install anything neither.

Upon loading the recovery screen, there is an error message :
E:Can't open /dev/block/platform/msm_sdcc.1/by-name/misc (Permission denied)

This error is also shown when I try to install a package (in this case, the beta version of SuperSU), which cannot be installed neither because :
E:failed to verify whole-file signature E:signature verification failed Installation aborted.
And the error message about misc is shown again.

I already forgot r thing with misc. You can find something about this mount in the recovery sources. Iirc, it has something to do with keeping things while flashing a new version
