PSP system software 6.35 is an official firmware for the Sony PSP, released in November 2010. It is one of the versions the PRO custom firmware is built for (PSP Custom Firmware PRO-C2). The update installs from the memory stick.

These are Sony's own EBOOT.PBP files, unchanged: one for the PSP-1000 / 2000 / 3000 / Street (PSP/PSP/GAME/UPDATE) and one for the PSP Go (PSPgo). Each one's PARAM.SFO reports the update as version 6.35, and each matches the MD5 listed for it in two separate Internet Archive collections of PSP firmware.
How to install / use:
Not included: Updating normally only goes up, so a PSP on a newer firmware cannot install this one this way.
Also on Digiex: PSP 6.61 Custom Firmware Install on any PSP, 1.50 to 1.00 Firmware Downgrader and PSP Official Firmware 6.61.

How to install / use:
- Copy the PSP (or PSPgo) folder from the zip to the memory stick, so the update sits in PSP/GAME/UPDATE.
- On the PSP choose Game > Memory Stick, start the Update, and keep the battery charged.
