To quote: This homebrew just does what the title says (plus unmounting, if you run it again).
Tested on PS3 3.55 (kmeaw, if you need me to be more specific). It should work on any firmware though.
This enables writing to the flash, which is vital to the operation of the console's operating system - use this at your own risk.
This homebrew was created using the PSL1GHT SDK.
Edit: in comparison with FreeFlash: this is ONLY using two syscalls (one for mounting, one for unmounting) - simple, efficient, and works.
Finally, from player21 comes How to Fix the "Downloading File From Target" Debugger Glitch as follows:
Hi all, after a few hours of dealing with this error, I finally decided to investigate and see what was going on.. For those who don't know what this horrific error is:
Whenever you open up debugger, it will set on a downloading dialog box and never finish
I'm here to tell you how to fix that!
First of all, you need to download MultiMan or any homebrew application that will allow you to have read and write access to dev_flash/blind.
1) Start said hombrew application and allow access to dev_flash
2) FTP into your PS3, this can be done through Target Manager using File Explorer
3) Navigate to /dev_blind/sys/external/ or /dev_flash/sys/external/
4) Copy all of the files there
5) Navigate to CUsers\User\AppData\Local\SN Systems\ProDG Debugger for PS3\flash_files\0404063e\ on your computer
6) Paste all of the files that you copied into that folder
That's all! It should start up fine once you do that
You should know, all of the files located inside of the external folder do not necessarily need to be copied over, but it's a whole lot faster than individually picking out the x amount of files that need to be transferred over.
*Note: If you can't view these folders, make sure that you go into your file and folder options and check "Show hidden files, folders, and drives."
