Update: Total_Noob has now released 6.20 TN-A Homebrew Enabler allowing homebrew on 6.20 PSP Firmware via the Patapon 2 demo savedata exploit.
Just under a month ago Sony released PSP System Software v6.35, and over the weekend some1 via wololo (linked abaove) has released a HBL Homebrew Loader for PSP Firmware 6.35 via the Minna no Sukkiri Demo Exploit by Jeerum.

To quote: some1 had been working with m0skit0 and JJS on porting HBL to this exploit. It is unfortunate that the release has to happen like this, but some1 had to release his files much earlier than expected because of the leak.
You can download HBL for the sukkiri exploit here. I haven't tested it yet, and we will be working on a "proper" release in the days to come. If everything goes well, we will probably drop support for the previous exploits (the golf ones at least), in favor of this one.
This release makes HBL work on 6.35, in theory (haven't tested yet)"
