Indeed it is a milestone thread Caty and far from dead. I think the only reason not much has been posted here for while is because the thread so comprehensively covers various uses of update.txt commands. pietu made the point that 90% of users wouldn't understand this thread but i think a 'normal' user can and will if they read it properly even without any additional posting of help from others. I knew nothing of this method [of course] when this thread started but following it taught me the basics no problem, so i moved from the 90% to the 10% also np [assuming pietu's figure is correct ;)]. My only confusion was over 'if_error' command and kunix enlightened me on that, i.e. it's not present in older unit fw, otherwise i wouldn't have had to ask anything [and i'm as dumb as dogs**t when it comes to this kind of stuff].Quote:

Like adrianm I have a couple of older units which will charge but not read or write over usb, even after reflowing. They would have been stripped for parts and the boards binned if it wasn't for Kanopus starting this thread [my eternal thanks]. Everything in their file systems can be dumped back to sd to check what's there already by copying region 48 [with most units] and then opening the .bin file with PowerISO or similar, not sure that will work with 2x0 series though as in some early units certain regions can be written to but won't copy. Maybe altering commands in firmware would allow that to happen in stubborn units but that's a job for the likes of Loly, Kanopux, kunix, pietu, Giomen et al if they want to try it because that does seem a logical progression of this thread, as is also maybe to try using Kunix's modded boot [[Only registered and activated users can see links.

Maybe that's total crap, i dunno. Just trying to gain some more attention from the experts to continue or reignite interest ....
I have many older units [SP510, nuvi 3x0, 6x0, 2x0, 7xx, 1xxx] to play with if any of you NSEs want to try that stuff but don't have an example of the particular unit to hand.
