thanks, it works with bm ???

This worked a treat on my Olimex 18F4550 Boards. they come with the Microchip bootloader so loaded it into pdfusb and cancelled the warnings to use the existing board settings. Was impressed that it works every time and retained the Bootloader.

Many thanks done the job. . Thanks for the promt reply

PSGrooPIC with PIC18F4550
PSGrooPIC with PIC18F4550 –
I am following the thread with PSGroove PIC18F2550 port for the whole week now. I had an order of 100x PIC18F2550 at Farnell but it looks like someone (or more of them) got the priority so the whole quantity of those chips (more than 700pcs!) was sold out today. The only alternative currently available is PIC18F4550 which is some kind of "big brother" to that 2550 version, but I can't find some information in that forum so I can't decide whether to order it or not. Therefore I would like to contact you directly with three questions:
1.) Does PIC18F4550 offer 100% same functionality as PIC18F2550? In other words, is it 100% compatible (and stable!) with PSGrooPIC code? Is one or another more stable (less resets needed when booting PS3)?
2.) Is there maybe a schematics/diagram available for PSGrooPIC also for PIC18F4550 version? I searched the whole forum, but I couldn't find a single advise or scheme with that PIC.
3.) Is there maybe a PSGroopic HEX available which supports bootloader and 4550 so I could update PIC18F4550 directly via USB when assembled?
Lastly, again as in first question. Is there an option to build a circuit with that PIC18F4550 which would be stable (maybe using a cap of 100nF between VCC and GND or something similar is needed for that version)? So, will that PIC18F4550 boot 10/10 or at least 9/10 times successfully?
Thank you in advance for your answers!
