and now the best for last:
3) fastboot boot your recovery into phone memory
this involves,basically,placing your recovery image inside the folder that contains adb and fastboot,booting the phone to fastboot,and the launching recovery into phone memory by entering the command:
fastboot boot recoveryname.img
do not confuse this with the
fastboot flash command.
fastboot boot is taking an image,and booting it right up on the phone.
fastboot flash is permantly installing an image into the phones filesystem.
ok,pay attention guys,cause im tired of typing this over and over in different threads
*if you use fastboot boot to launch your recovery into phone memory,then recovery CAN write to the boot partition,making rom flashing on your s-on device just like rom flashing on an s-off device.
i.e.,launching recovery from fastboot lets the rom install the kernel,and requires no seperate kernel flashing. this means that when you are following a rom developers install instructions,you can follow the set for s-off devices.
why does this work?!
well,an oversimplified explanation is this:
-fastboot is part of the bootloader,wich can write to the /boot partition
-launching recovery from bootloader,makes the recoverys operations work thru the bootloader.
-hence,launched recovery can write boot image. hooray! :smokingsomb:
all the above applies to bakcups as well. you canot restore a backup from the permenent recovery if it contains a different kernel. just like flashing a rom. all the above info in this post applies to restoring a rom as well.
2)
launch a temporary recovery:
-temporarily launch your recovery to phone memory:
fastboot boot <recoveryname>.img
again,if youre using amon:
fastboot boot recovery-ra-vigor-3.15-gnm.img
-youll see a (really fast) green status bar on the top right as your PC sends the recovery to your phone. youll then see the
HTC splash screen,then your recovery.
now that youre recovery is running,you have lots of options. you can mount usb storage to move things on and off the sd card if you need to.
...
note that once recovery is running,you can unplug from the PC if you want to flash your rom from the couch,ktichen table,or wherever
