(adsbygoogle = window.adsbygoogle || []).push({}); Hi NGU I was on 4.21.1 REBUG and I wanted to cuztiomize my ps3 a little more you know so I wanted to cuztiomize the ps3 waves and make them all cool looking and stuff I was using REBUG Toolbox as my FTP server ok so I was going to replace the files so I could customize the ps3 waves so whean I quited out of REBUG Toolbox then my os3 told me to plug in my controller so I did it put me in recovery mode so I contacted the guy that downgrade my ps3 he just told me to re-install the frimeware so I did all the steps on my ps3 I made a folder PS3/UPDATE/PS3UPDAT.PUP ok so whean I plugged in my USB and went to system update it detected the update.pup so it was copying the update and whean it went to 99% and stayed on 99% for like 20 minutes so I panicked and called the guy he say just leave it alone and let it do its thing so I waited like 6 hours and still on 99% so he said I'm stuck in a update loop he said I used corrupted files so he said he now has to format my hard drive and Reflash and downgrade my ps3 and that's another 40$ so I'm here seeing if there is another solution or any other help to get passed this or anything please reply or something thx.

Try formatting your hard drive yourself.

Formatting your hard drive will get rid of you file's but I don't think it will remove the cfw since it's not stored on the HDD. So becareful he might be trying to get more money out of you.

That's not right, most of the firmware is stored on the HDD actually, only 16MB is stored on the NOR flash, unless he has one of the early FATs with a NAND flash where all of the firmware would be stored.

Oh I see, thank's for the correction! You learn something new everyday! haha

This really sound like he's trying to exhort money off of you, he's the one who is providing the service and did the downgrade but yet he is charging you to format the Hard drive which a 12 year old can do with simple instructions. he should've at-least charge half the price since you were already a customer and it could've been his mistake. Before you go and dish out another $40 try this as It helped the guy who had the same problem as you. Use the Same Cfw that you already have in your case 4.21.1 REBUG since your not updating or downgrading and it's partially install on your ps3
1. Unpluged ps3, and removed hdd.
2. Plugged hdd into a external hdd enclosure, and plugged that into my pc.
3. Opened up Computer Management (look it up people) > Storage > Disk Management. Then I found my hdd, right clicked it and chose format, follow the utility choosing NTFS as file system, default allocation, and do a FULL FORMAT. Let it sit, its gonna take awhile, especially if your using USB 2.0.
4. Stay in Disk Management, right click your drive, click "Mark Partition as Active"
5. Pop the hdd back into the ps3 and go to recovery.
6. Choose "Update System"
7. Get a flash drive and put PS3UPDAT.PUP on it. read it on Sony's web site, search "ps3 firmware" on google if you need to.
8. Plug in flash drive to ps3, hit start + select. It will then bitch and say it needs to format the hard disk. Hold start + select till the process starts.
9. Congrats! firmware should flash and start its process.
P.S. This will fix the following errors: 8002F281, "The hard disk cannot be accessed", or "Correct hard disk was not found"

thx guys how much is that usb you connect into the hdd into the computer....?

O and I have a ps3 slim.

an USB enclosure is use to make internal Hard drive act like External via USB which usually go for at least $8-10 for an SATA Price rises for brand and quality with multi function
