I've got a bigger issue now... I used BootBox to create series of slides which previewed OK. This hangs my phone with the 2nd last picture displaying, I feel a vibrate shortly after.
I can get into ADB at this stage but don't know linux commands or Android internals, from Googling I thought this is what I could do:
* ADB SHELL
* mount -o remount rw /system
* cd /system/media
* ls -l
* cp /sdcard/goodbootanimation.zip ./bootanimation.zip
* ls -l
I'm not sure "SU" is doing anything, the shell generally just repeats what I type and the googled solution of copy/pasting instead sometimes works. I'm not sure I need it anyway this is my command prompt "255|shell@hammerhead:/ $". (does that mean I have root access already?)
The mount fails with "mount: Operation not permitted". The copy fails with "cp: ./bootanimation.zip: Read-only file system"
I've now worked out how to install the drivers for ADB for recovery, while the driver loads ADB on windows can't see the device:
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
I've also Tried Recover->Apply update from ADB", got "device not found".
I'm rooted with unlocked bootloader and stock everything else. I do not wish to factory reset and lose all my configuration..
