After changing the ROM ROM ZVA for the ROM ZV8 the folders were lost ¨data¨, ¨omadm¨, ¨property¨ and the ¨legal¨ file, content in the carrier file folder.
Through the Root Browser application could restore the folder ¨property¨ since I have available to make the procedure of unlocking gsm, but I have other folders and the file is lost.
I would like to know that I may have problems using the phone without these files. What can I do to recover?
Lost files circled in red in the attached image.
