The router works fine, but it slowly accumulates bad blocks.

I did it all. Bad-blocks 0,0%.Please use Netinstall to upgrade your router (install 6.38.7), upgrade RouterBOOT by /system routerboot upgrade and /system reboot.
Make sure not to write logs to disk. Let us know about the results.

I wrote 100MB to NAND and 0.6% of bad-blocks appeared and when I repeated this operation, 2.1% of bad-blocks appeared.[admin@MikroTik_RB493G] > system routerboard print

1) Manual repairs are not supported (maybe you've seen "warranty void" stickers on nearly all consumer electronics, this includes software warranty).I have similar issue.
Today MT support refuse license update after NAND replacement for RB493G. As well doesn't offer paid repair.
Think twice before buying MT, one day you will be left behind...
From Mr.Gennadiy51 last comment was on "Thu Dec 07, 2017 1:21 pm" .Thank you for reply!
If manual repairs not supported oficially, then how Mr. Gennadiy51 has got new license free of charge after manual NAND repair ? Please see above posts.

Could you share nand chip details model, pics or how to locate and replace nand...My story ended happily!
I wrote in support that after the replacement of NAND the license was lost and attached the photos:
1. RB493G_SerialNumber.png - the photo of my Routerboard with the serial number and both the old and the new NAND chips;
2. RB493G_Winbox.png - the detailed information about [Routerboard], [License] and [Resources] from Winbox;
3. supout.rif - RIF file corresponding to the newly used NAND chip.
The next day I received a license key without additional questions.
Many thanks to the MikroTik!!!
