RB1200
RouterOS 5.23
Firmware 3.02
If i reboot, it fails. If I turn it off and turning it back on, it works.

No.
The problem is intermittent and RouterBoard was not open.
The problem is either in the factory or is firmware 3.2!
same problem…what is the solution???
Same Problem.
3 RB1200 same firmware/RouterOS
Current Firmware 3.02
RouterOS: v5.24
Who can send request to support@mikrotik.com to try to debug this problem?
I have my 3 RB1200 1000Km far from me.
Same problem: Firmware 3.02 and v6rc11
My solution:
downgrade to 5.11, downgrade routerboot, change RAM module to kingston 2gb.
Now it has 5 hours uptime…I tried to reboot it 3-4 times…everything OK. I will see tomorrow.
Took delivery of my first RB1200. The first two times I applied power, it failed to boot: no initial beep, not even output to the serial port. The third time it booted into RouterOS normally. After / system reboot, it stopped after displaying “Restarting system.” and I had to remove & reapply power–which occasionally works, but usually does not.
Overall I’m seeing ~90% failure to run the boot loader upon power-up or reboot command. I see a slightly better rate if I hold down the reset button to force the default boot loader, but even that fails to load much of the time. Sometimes the green LED will come on and stay on; sometimes it doesn’t come on at all. Rarely, the boot loader will start but print garbage rather than the “MikroTik” logo, sometimes it says “not an elf header” and tries bootp, then locks up before it finds the netinstall machine.
None of the following measures have made any difference:
So… does any of this look wrong (particularly the PCI settings)?

After (re)installing 5.24 and the 3.02 boot loader, I ran a series of tests last night. 11 of 34 cold-boots failed, and 15 of 36 soft-boots ( / sys reboot ) failed. In every case, the failure occurred before the boot loader was able to send anything to the serial port. Conversely (or contrapositively 
), if the boot loader launched successfully, it would reach the ROS login prompt every time.
It didn’t seem to matter how long the box was left powered on or off, or whether it was a cold-boot or a warm-boot, so I don’t think it’s a heat issue. It is as though the main board or memory board has an intermittent, low-level problem (race condition?) that makes it a coin-toss whether the boot loader will launch or hang.
At this point it’s a curiosity, as I will be returning this box–but now I’m concerned that this might be a systemic problem that affects a certain production run, rather than an isolated defect. FTR, the serial number of this particular unit is 2D720112642D/121, and the MAC range is 00:0C:42:CF:30:9A - A3.

I have 2 pieces od RB1200 on the desk. Both are freezing + failed booting 
… no answer from Mikrotik.
//if you change original 512mb ram to kingston 2 GB …random rebooting will disappear. But I havent got enough courage to deploy it on network.
//with original 512mb ram…router upgrade from 5.11 to → 5.24 will fail on boot…kernel error..now with 2 gb ram upgrade from 5.11 to 5.24 without any problem…
I’m having the same problem. Just bought an RB1200, upgraded to 5.24 - rebooted - it won’t boot. Had to disconnect and reconnect power to boot it. Upgraded firmware to 3.02 and rebooted (again, had to disconnect and reconnect power to boot it).
But now reboots are working (tried 5 times in a row, it reboots ok now). I’ll leave it running overnight to see if it reboots like the ohters have mentioned. Damn, I planned to deploy this one on site today.
I have a similar problem, Brand new RB1200 that I upgraded all packages to 6rc14.
The unit will reboot on command, but if I shutdown or power off the unit it will not boot unless I hold in the reset button and then plug in the power. The unit beeps after a few seconds and then boots ok.
Is there any fix for this if there is a power cut and the UPS runs dry then some has to go to site and pull it out of the rack and push the button!
Thanks,
Guy
Update - the unit does reboot, it just seems to take 60-90 seconds before it ‘beeps’.
I’m happy enough 
Try upgrade to V6
*) fixed crash on RB1200;
Same problem here with brand new RB1200 - as in same as Hotz1 is getting: randomly on reboot the system never starts up, with no output on the serial terminal at all after “Restarting system.”
If the boot starts, everything works perfectly. If boot doesn’t work, pull power and reinsert has worked each time. Failure to boot seems to be about 1/3 of the time
Experienced the problem on all of these so far (in order):
Original firmware as shipped 5.11, boot 2.37
Upgraded ROs to 5.24, boot 2.37
Upgraded bootloader to 3.02, still ROs 5.24
Upgraded to ROs 6.2, upgraded bootloader to 3.07
After going to 6.2/3.07, problem seems to be less…maybe 20% of reboot attempts lead to no boot…but that’s anecdotal on only about a dozen reboots.
I haven’t tried any downgrades, reducing CPU freq etc., as these don’t seem to have any affect for anyone else.
having same issues with two rb1200 with 6.2/3.07,
any ideas how to solve it ??
ANYONE ??
Try 6.3 http://www.mikrotik.com/download/share/routeros-powerpc-6.3.npk
