As we can know, I'm new in here and I'm wanted to get some answers. I Have read many topics, watch videos and etc.
First I Want to talk about E3 flasher. Can I Downgrade my PS3, when I Have latest version (4.21) in my PS3 model? Also I Checked my minimal downgrade version and it was 3.40 and my model is PS3 Slim CECH-2540 B. How can I Know, do I Have NOR flash in my PS3 Slim? If I Know right you need to have NOR flash?
Second, can I Use Eclips3 USB dongle for downgrading process? Do I Need to program it, before use it on downgrade process?
Third, I'm not sure, can you share E3 flasher and USB dongle shops here, but do you think I Can get real ones from here: http://www.oz3ds.com/
? This was the best place, what I Found, others are too expensive and this company provides free shipping.
EDIT: Which screwdrivers I need to use, if I'm going to buy and install E3 flasher limited to my PS3 Slim 320 GB?
Thanks for your reply in advance!
