Backup android to ubuntu from recovery mode -


i have - stupidly enough - updated android phone newest 5.0 lollipop. update went bad , many hours later phone still unresponsive. can enter in recovery mode. have seen in forums many other users had same problem , turns out way out factory reset of phone. means total loss of phone data. have no backups (as far concerned) wondering if there simple way transfer data phone computer (ubuntu) while phone being in recovery mode.

this tried already:

  1. started phone in recovery mode
  2. selected 'apply update adb' (as apparently way computer sees phone through $ adb devices)
  3. i type
$ adb devices list of devices attached  02452a1acc14c9d4  sideload 

and then

$ adb backup -apk -shared -all adb: unable connect backup 

my phone not rooted, pretty sure usb debugging activated. ideas? possible @ backup phone in recovery mode?

thanks in advance.

helps know phone have. key sequence needed boot recovery mode. i'd flashing clockwork mod recovery can mount phone on usb while in recovery. there copy new rom zip flash on messed lollipop rom.

all have format /system , install known working rom. also, clockwork mod recovery can make nandroid backup can looked @ using titanium backup can extract data way.
