Some time ago I read this thread, (very old and related to 4.2.2... I know!) promising to implement it as soon as I rooted G2. - I rooted today, but unfortunately in the path /persist (hidden directory) there is no trace of files is empty.
So the procedure is not applicable. I could however copy files rct and rct.cfg in the directory, but I want to avoid getting a device not bootable or not functioning. there is another alternative way to restore the file. tot, then the kdz? I have read that if you connect the G2 to LG PC Suite and it makes the update error correction root is removed from the phone. Is so ???
If the discussion was already posted, I apologize to everyone. Unfortunately, English is not my language and I have a lot of trouble with the search.
