Hi... ive downgraded using the old downgrader for 2.71 and thus have some corrupted keys. One of the problems ive experienced is the psp does not switch on if the batt is less than 12%
Then i found this keycleaner which says it fixes the keys.
Now for those who know abt it or have used it... plz let me know if its reliable and if i can continue using backup iso files (i am currently on 3.40oe-a and can use them without problems)
The link to this application is:
Is there any side effects by using this application?
Any reply is appreciated.
Thanks and plz do reply if u have any idea.
