Nokia-N800-51:~/initfs_flasher# mount -o remount,ro /dev/mtdblock3 /mnt/initfs
*** glibc detected *** double free or corruption (fasttop): 0x00047050 ***
Aborted



Can someone please, or multiple people please run this command, it will not cause any problems. I just want to see if this works for others or if all n800 get this error?

mount -o remount,ro /dev/mtdblock3 /mnt/initfs

then do a

df

and please post the output.

Thanks in advance!!

Firmware 2.2006.51-6. My N800 has no known issues at this time.

Note that even though the mount command appears to have failed, it has mounted /dev/mtdblock3. And if you execute the mount command multiple times, you'll end up with multiple instances of /dev/mtdblock3 being mounted at the same mount point!

Thanks for the response, you confirm that it is a bug, and not hardware problem.

You need to install becomeroot or flash to R&D mode to be root. You need to be root to run this command. Milhouse has confirmed it for me though. Thanks for trying!!

I knew someone would suggest how...I will try becomeroot. Ta

Yes, just install becomeroot and then use, sudo gainroot, to become root!!!
