How to revert 4.87 PS3 from demo mode

[LEOGRAY]

Hi everyone. I have superslim PS3. And as i remember 2 years ago it was on 4.81 OFW. And my cousin updated it to 4.87. I don't know what is going on but somehow its one demonstration mode. I saw that there is reverters for this kind of situations. But there is no 4.87 version of it. And i can't even update it to 4.87.1 HFW. It says that the data is corrupted. What can i do ?

I tried to downgrade it to 4.86. Did not work. I tried with another hard drive still can't do it. Every time i try to update the system on Safe Mode it says "The data is corrupted 8002f2e4". Please guys, If you have an idea or something let me know. This is not my PS3. Its my cousin's, he died because of diabetes. He has a little son (10yo). I wan't to fix it, install HEN and some games so he can play his dads PS3.

Thank you. But I already know about that and I changed the password. But its not a solution. What i am asking for is there a reverter for 4.87 to get rid of demo mode.

grab it here and put file in this folder structure on pendrive \PS3\UPDATE\PS3UPDAT.PUP
- on black first folder PS3 contains UPDATE folder,
- on green pup file.
All folders and file must be case sensitive
To install you must be in recovery mode.

Sir, you are my hero. I was looking for this file for 6-7 hours today. I have tried lots of things, none of them worked. I wish you a good day. The thread can be changed as solved.
