If you read the first link, there are written that it, cant launch (now) any application. Well, I just already installed it and I'm on n33 again but it works, it's not a bricker. He uses the recovery and one application by himself for return to n33.
Better read the link, he explain it better.
He say that doesn't have the vshctrl completed, but the reboot150 yes.

Readme - Instructions
Install it from 3.90 m33. Only for fat yet (if I continue, read 'another information')
Then of reverse all M33's flasher, I leave the flasher here, for the people that likes test.
Recovery folder is the uninstaller, if you install GF, then put RECOVERY folder at GAME folder. Run the app with the recovery option called 'run program at'.
Else if you want install it, copy GFUpdater to GAME380 folder, and put the GAME Folder homebrew from recovery to 3.90 kernel if you don't have it.
It has now, a small sdk.
Copy config.txt at \psp\system\GfSystem .
0 indicates the disabled state, another number the enabled state.
· Removed devkit version patch. When I have it completed, it will be added again.
· Patched done for make gfplugins and GFSystem folders automatically when you connect the PSP using usb (only it will make the folder/s if it don't exist, it uses the function gfctrlMkdir (more information of it at vcmp sdk header). It isn't the same patch that apply DaX.
· DaX flasher reversed.
