Hi to all! Well, I opened my mp4 player, do all i have to do, it was recognized as Adfu Device by Windows, start the upgrade tool, saw the message "Now is recover state...bla bla bla", but when i click in "Recover Firmware" my player show a blue screen and this message appears: "Read or Write device information failed! Please exit the program and check if device is connecting!", the blue screen turn off. I used the full firmware!

Thanks

Sorry about my english!!! :wink:

serp, Does this happen with every full version you try? Also try connecting to a different USB port. Also try the Product tool HERE it is a commercial upgrade tool. If you notice the Erase Flash button become active use it to format your flash before upgrading.

with others full firmwares appears the message that is not the correct file! I'll try this program and post the results!

serp, Unfortunatly I am only guessing as I never had this problem when recovering any of my players.

I only saw the same problem with 2 users of other forum, but they had not gotten success in solving the problem, yet! I read something that says that this problem is caused by the battery, and I would have to detach it and put it again to solve the problem, but I really don't know...

Any idea, I accept!

Thanks a lot

serp, I remember reading a post by a member who had the same problem, when it was suggested he try a different computer he only had an old PC running Windows 98 and fixed his player first time.

Regarding the battery you could try disconnecting it and then connecting your player without any power you possibly have nothing to lose by trying.

Here is the topic of the other member with the same problem (but he did not post the fix):

If it's any consilation, i'm having the same problem. I short the device to load firmware, and now it's giving me the read/write error. (problem after problem with me)

I can't erase flash because it's not highlighted!

I'm buying a new computer on tuesday with XP. I think windows 98 may be the reason i'm having all these problems!!

I'll let you know how things work out.

I use win XP here and the problem continuous. I'll try win 98 as our friend tadad1 suggested!
