Hi CHOKRIMAATOUK,

You may want to try a full flash of rootfs+emmc although I am doubtful it would help. If it does indeed help it would really be a good thing as I understand your pain.

If you need to send it to Nokia Care what you can is call the Nokia Care Centre directly in Oman and inform them you have this device that a friend helped you purchase as your country didn't have it. Now it has its flash memory screwed and you need them to repair it.

They would give you their address and if you mail it to them they'll usually fix it and mail it back to you...

At least that's better than having to bin the device
