(adsbygoogle = window.adsbygoogle || []).push({}); So I downloaded 4.75.3 d Rex and 4.75.3 Rex when I try and update Via usb it says data corrupted so do I need to downgrade to 3.55 then go to ether one of those updates and if so do I have to redowngrade with a e3flasher

Tried that didn't work

Idk about other methods, but this is how I do it:


get c2d and openssl
c2d_openssl

make sure to go to C:/ , and the folder named "Win32Openssl" or something like that, rename it to "openssl"

1. Install Rogero Downgrader.pup 3.55 Rogero Downgrader RSOD
2. Download "Eid Root Key Dumper For 3.55" You must login or register to view this content.
3. Install Eid rootkey dumper.pkg to your ps3
3. Run Eid rootkey dumper.pkg

Your console will restart

5. Install Rebug 4.46(or any rebug cex for this ex I was using 4.46)

4. Use Filezilla to retrieve your eid_root_key from dev_hdd0/tmp/eid_root_key

5.Put a fat32 formatted usb flash drive in the right side port of your ps3
6.Open rebug toolbox, go to furthest right column and select "Export Flash to file"
You then have 2 files altogether
---------- A. Eid_root_key
---------- B. XXXXXXX-XXXXXX-FLASH-NOR-FW4.46.NORBIN


6. Put them in a folder somewhere safe


7. Make a copy of "eid_root_key" and name it "eid_root_key.bin"(no quotes)
8. Make a copy of "XXXXXXX-XXXXXX-FLASH-NOR-FW4.46.NORBIN" and name it "CEX-FLASH.EID0.NORBIN"(no quotes)
9. Make a copy of "CEX-FLASH.EID0.NORBIN" and name it "FLASHCEX.BIN"
Make DAMN sure you don't leave it with a double extension (ex CEX-FLASH.EID0.NORBIN.NORBIN, FLASHCEX.BIN.BIN)

10. Copy "eid_root_key.bin" and "FLASHCEX.BIN" to where c2d.exe is located
11. Hold shift and right click an open spot in the folder, then select the option "open command window here"
12. In the cmd that has opened, type "c2d.exe eid_root_key.bin FLASHCEX.BIN FlashDEX.bin 82"(no quotes)
The "82" represents the region

13. along with your "FLASHCEX.BIN" and "eid_root_key.bin", you will see a new "FLASHDEX.bin" file
14. Rename "FLASHDEX.bin" to "DEX-FLASH.EID0.NORBIN"
15. copy "eid_root_key.bin", "CEX-FLASH.EID0.NORBIN", and "DEX-FLASH.EID0.NORBIN" to the root of your usb flash drive
16. put the usb flash drive in the right side port of your ps3
17. Go to rebug toolbox, second column from the right, and select "rewrite target ID in Flash"
it will ask are you sure click yes
18. Then, select the option "Swap LV2 Kernel"
It should successfuly swap to DEX/Debug
19. Install a DEX cfw like Rebug 4.75.3
