Here you go people, A no filesystem error 65KB USB image for those that use a chip with a usb drive. This one is even smaller than my last mod and gives no filesytem error once that exfat hax is running.

This is about as small as I can make this, but I am sure someone can make it even smaller if you can figure out how to adjust the offsets for the start of the fat16 partition. (this will be somewhere in the first 512 bytes of the image). Exfat hack is stored at the start of the image, fat16 partition (only 512 bytes) starts at offset 0x10000. Because PS4 can read this, there's no error detected and no need to format on a PC error will show up either.

I have tested the usbimage on my ps4 and it works perfectly. The message to remove the usb does not appear, but you just have to wait a few seconds and click on the accept button to load the jailbreak.
Great work!

What is this for, and what does it do?
It's for people that use a chip such as this here (https://github.com/stooged/PS4-Server-900u) that want to auto jailbreak their v9.0 PS4 without needing to manually insert a usb drive into their PS4 to jailbreak it. Usually exfat pico images that people flash to their USB drives give a filesystem error when the USB drive is inserted into the PS4 because there's no filesystem in the USB drive.
On these images the exfat hack is on the first few pages of the usb drive sectors and this is what crashes the ps4 and lets you push the hack. However the usb causes a filesystem error because there is no partition info or filesystem on the usb. This image that I have attached contains the hack, but it's been modded to contain a partition table and a fat16 filesystem table that the PS4 thinks is exfat. The PS4 can read this (along with the hacked sectors), so doesn't know there's an error. Also you can put the usb in a computer afterwards and get no "you need to format this error", so you can use the existsing space on the drive to create another partition and still be able to use your usb drive for other stuff.

Thx for the good explanation B-)

  • TwoSpikedHands @ TwoSpikedHands:
    I just found out that the EU version is better in literally every way, better sound quality, better lighting, and there's even a patch someone made to make the text look nicer
  • TwoSpikedHands @ TwoSpikedHands:
    Do I restart now using what i've learned on the EU version since it's a better overall experience? or do I continue with the US version since that is what ive been using, and if someone decides to play my hack, it would most likely be that version?
  • Sicklyboy @ Sicklyboy:
    @TwoSpikedHands, I'll preface this with the fact that I know nothing about the game, but, I think it depends on what your goals are. Are you trying to make a definitive version of the game? You may want to refocus your efforts on the EU version then. Or, are you trying to make a better US version? In which case, the only way to make a better US version is to keep on plugging away at that one ;)
  • Sicklyboy @ Sicklyboy:
    I'm not familiar with the technicalities of the differences between the two versions, but I'm wondering if at least some of those differences are things that you could port over to the US version in your patch without having to include copyrighted assets from the EU version
  • TwoSpikedHands @ TwoSpikedHands:
    @Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
  • The Real Jdbye @ The Real Jdbye:
    @TwoSpikedHands just switch, all the knowledge you learned still applies and most of the code and assets should be the same anyway
  • The Real Jdbye @ The Real Jdbye:
    and realistically they wouldn't

    be able to play it legally anyway since they need a ROM and they probably don't have the means to dump it themselves
  • The Real Jdbye @ The Real Jdbye:
    why the shit does the shitbox randomly insert newlines in my messages
  • Veho @ Veho:
    It does that when I edit a post.
  • Veho @ Veho:
    It inserts a newline in a random spot.
  • The Real Jdbye @ The Real Jdbye:
    never had that i don't think
  • Karma177 @ Karma177:
    do y'all think having an sd card that has a write speed of 700kb/s is a bad idea?
    trying to restore emunand rn but it's taking ages... (also when I finished the first time hekate decided to delete all my fucking files :wacko:)
  • The Real Jdbye @ The Real Jdbye:
    @Karma177 that sd card is 100% faulty so yes, its a bad idea
  • The Real Jdbye @ The Real Jdbye:
    even the slowest non-sdhc sd cards are a few MB/s
  • Karma177 @ Karma177:
    @The Real Jdbye it hasn't given me any error trying to write things on it so I don't really think it's faulty (pasted 40/50gb+ folders and no write errors)
  • DinohScene @ DinohScene:
    run h2testw on it

  • DinohScene @ DinohScene:
    when SD cards/microSD write speeds drop below a meg a sec, they're usually on the verge of dying

  • Psionic Roshambo @ Psionic Roshambo:
    Samsung SD format can sometimes fix them too
  • Purple_Heart @ Purple_Heart:
    yes looks like an faulty sd
  • Purple_Heart @ Purple_Heart:
    @Psionic Roshambo i may try that with my dead sd cards
