No because I'm unable to install it.

The sandisk firmware is always installed.  Hold left when powering on to boot it.

Thanks blank screen as well with original firmware. :(

It sounds like your player has a broken screen.  Start a new thread if you have questions, this one is about fixing a problem with clipv2 frequency scaling builds.

Yes, you are correct. Many thanks for your help :). May I ask what the problem was and how you resolved it?

@saratoga: Thanks for your help also.

After adding frequency scaling we have overclocked display port.

Looks good.  Do you think it's time to put in the voltage changes and do this all over again when things break :)

Yes, current build is broken.  What am I missing?

Edit:  I don't see anything obviously wrong and don't have time to dig into this right now.  I'll just disable it again until its fixed.

I mean another code, not related to voltage/frequency scaling. IMHO for lebellium report we just should rise voltage. I have made test build and I wait for him in IRC.

I also have the same problem with a Sansa Clip Zip; buttons work fine, the display is fine on the firmware load, but on Rockbox I get a black screen, no loading page or anything. Every now and then in a dim room I can see the display is on, but very faintly.

http://knk.square7.ch/rockbox-5.zip might fix my problem but the link is broken. Does anyone have a reupload?

Can you try reset config (just remove .rockbox/config.cfg)?
