Hi there,
I've installed couple of time a new ROM due to different errors of configurations.
And the end of the day, I wanted to retrieve my previous version thanks to my backup, and here arrived my issue...
I cannot install the backup or any ROM. No error message
But when I wipe I got this:
Code:
Updating partition details...
E: error opening '/data/data/com.samsung.sharehot'
E: error: too many open files
E: error opening '/data/data/com.samsung.sharehot'

Someone can help me with this strange issue ?!
Thanks a lot
Nicolas
