1. Reboot into recovery
2. Make sure /data partition is mounted via recovery (under mounts and storage)
3.
Code:
adb push *nameofROM*.zip /data/media/*nameofROM*.zip
If you have titanium backup you should be able to even salvage some data/apps from your backup (this may be a pro feature).
Alternatively there is a way to generate an md5sum via adb as well (in recovery with /data partition mounted) so you can potentially salvage the backup.
Code:
adb shell
su
cd /data/media/clockworkmod/backup/*nameofbackup*
md5sum *img > nandroid.md5
^that may take some time, it took quite a while on the OG Droid, I haven't done it yet on the GN.
If you don't know the name of the folder you can do:
Code:
cd /data/media/clockworkmod/backup/
ls
