OK confirmed PS3go is working with factory / service mode with new update! (V10 core) How it works:
1. download this attachment, unrar it.
2. plug ps3go to computer and file update.bin goes to ps3go root dir. (flashdisk not TF!)
3. unplug it and plug it in again (this will flash ps3go to V10 core)
4. send file update.bin again to ps3go root dir and rename it to downgrade.bin
5. use normail jailbreak procedure (press start and enject) to switch on ps3
6. turn off system via xmb.
7. powen on and its factory / service mode!
rename downgrade.bin to anything to disable ps3go factory/serivce mode.
any question you can PM me I'd like to help out!
