[Q] How to retrieve data from, and wipe a damaged phone
I damaged my phone after dropping it. Now I'm trying to recover my data from the phone, and also wipe it, before I send it to the service centre.
1. Screen, touch, and possibly more is damaged.
2. It boots to a certain extent (not sure to what extent). Holding the power button for 3 seconds causes flashing of capacitative buttons, and a quick vibration (similar to how I force reboot when it was working). Obviously, I couldn't tell how far in the boot process it went.
3. Searching for answers, it seems like my best bet would be adb. I can't remember whether I enabled USB debugging on the phone (I probably had at some point, just hope that I had not disabled it). Connecting it to PC via USB and then typing the adb commands showed the phone in an "offline" state.
4. dmesg output:
[ 4239.366740] scsi15 : usb-storage 1-1.1:1.1
[ 4239.575414] usb 1-1.1: USB disconnect, device number 11
[ 4240.284869] usb 1-1.1: new high-speed USB device number 12 using ehci_hcd
[ 4240.390958] scsi16 : usb-storage 1-1.1:1.1
[ 4241.390427] scsi 16:0:0:0: Direct-Access HTC Android Phone 0000 PQ: 0 ANSI: 2
[ 4241.391633] sd 16:0:0:0: Attached scsi generic sg2 type 0
[ 4241.403112] sd 16:0:0:0: [sdc] Attached SCSI removable disk
5. The line "[sdc] Attached SCSI removable disk" made me quite hopeful, but unfortunately when I tried to mount /dev/sdc, I got
mount: no medium found on /dev/sdc
I feel that my best bet would be to get the "offline" adb device "online"
Any advice, please?
