You turned on logging to disk (in this case your internal nand flash)? It is not about the number of lines but frequency of the same block rewritten. The nand writes on these embedded devices usually don't have wear levelling on it and require wear levelling on the software level (such as jffs filesystem) on user writetable partition. I don't know if routeros used any flash optimised file system to handle wear leveling for internal flash storage. You should use external USB storage if you have frequent writes to storage.
Anyway net boot procedure for mikrotik is very specific not the usual generic reset sequence nonsense usually mentioned in ddwrt/openwrt. The following site explains it pretty detailed each

My RB951G already reach of total of 3million writes and its already 2 years old. My scrips update every 24 hours (for ip blacklist). Its quite sad when newer model has smaller nand flash size (16 vs 64/128mb)

My oldest RB951G is 3.5y but only 380K writes. As long as the write is not on the same block too frequently, it is fine. RB951G is using slc nand. Newer model use spi flash instead of slc nand flash. Older model also may have small spi flash for some critical stuffs. Apparently routeros does have some sort of wear leveling mechanism according to mikrotik website & slc nand had 100K cycle endurance.

shengz My home's RB2011UAS is almost 4yrs old (bought Apr 2013), 800k writes, still OK. At one time I had it logging to a syslog server. A few months ago I set it to log to a USB thumbdrive. Yeah, I was worried about the nand also.
I have deployed about 50 RBs in various roles and except for 2 PSUs, none have died yet.
Fingers crossed.
Good news here, it is alive and kicking now! I re-check the bad block, it is only 1%, so looks great. Why it went haywire and soft bricked, no idea, since everything were setup, left there and nobody touches it anyway.
Here is what I did for those who have hard time with netinstall. We were lucky to have Google in this era.
If netinstall could not detect the router with these settings below,
Set static IP of 192.168.88.3, subnet mask 255.255.255.0, gateway 192.168.88.1 on PC
Run NetInstall
Select "Net Booting"
Mark "Boot Serve Enabled"
Set Client IP address to 192.168.88.1
try these instead,
Set the adapter's IP to: 10.0.0.1 and subnet mask to 255.255.255.0 (Leave rest of the settings blank)
Run netinstall.exe
In Net Booting option: Check Enable Boot Server & set client IP as: 10.0.0.2
Credit goes to the teachers.
Bad news is, I bought another new RB951G as trying the same netinstall settings for 2 days yet can't get it working while my TP-Link runs Streamyx 4Mbps alone is making me very very very desperate for the previous speed.
