iAudio X5 - bad checksum error

[great_badir]

Hi all -

I have searched the forums and can't find anything with this problem, at least not in the way it's happened to me...

I have had Rockbox on my iAudio X5 for about 5 years now.  Last Wednesday it was working absolutely fine.  On Saturday it wasn't.  NOTHING happened to or with the player in between those days - no files were added or deleted, the player was not charged (it had been fully charged on the Monday), it was not dropped, it was not hooked up to a PC or laptop, in fact it wasn't even switched on.

The error reads something along the lines of:
Numerous things and numbers;
Bad checksum error!
Can't load rockbox. iaudio: unknown.

And then the screen very quickly goes black and the player switches off.

I've checked that I am using the right version of Rockbox and the firmware and have tried everything I can think of - reflashing a new version, completely deleting and re-installing Rockbox both manually and with the utility, removing Rockbox, going back to the iAudio firmware and then reflashing Rockbox again.  I've lost count of the number of times I've done all of these and nothing has worked except just going back to the iAudio firmware - there don't appear to be any problems at all with that, but this is unacceptable to me, mainly because the iAudio firmware is rubbish.

Can anyone help sort this massive problem out?

Thanks

After completely removing Rockbox and checking the drive for errors, which versions of Rockbox have you tried to install?  (Please give the version or revision number.)

I have only tried version 4 and whichever version was around 5 or so years ago (I don't have the hard drive that the zip file is on to hand at the moment).

I am still in the middle of running a drive error check - I'm doing a full scan including bad sectors - but, presumably, if the iAudio firmware is working without issue, isn't it a software issue?

I'll admit I am not overly technical...

You should really be installing a current build or the most recent release.  We don't support such old builds.

Version 4 is the one I downloaded from here at the weekend in the current build section - at least when I switch on the player it says version 4.

That would seem to be the bootloader version rather than the firmware version/revision.

Ah, okay.  Well, I downloaded the one that was on there on Saturday (which said r29792 underneath it then and I see it still does now, so I assume there hasn't been a new one since Saturday) and I just tried it again, both manually and with the Rockbox Utility.  Still have the same error message coming up, still absolutely fine when I flash it back to the iAudio firmware.

I think you are mistaken about the revision you tried on Saturday.  It looks like more than 20 revisions have taken place between last Saturday and the current build, which is r29793 as I post this.

Unfortunately, I don't have a good idea of what's causing the behavior you're seeing.  I will let you know if I find anything.

Okay, thanks Chronon.

Like I said, I downloaded the (then) current version last night, but it's the same error over and over again.

I'm wondering whether the best thing to do might be to format the whole disc and start again from scratch
