Hi, everyone,
I have a routerboard RB435GUAH. i used it for about 1 year, it was fine.
last week I soft reboot it by click the "reboot" button in the winbox. and it never comes back.
No sound after boot. (before, when it works fine, it play two sounds after boot. )
when plug the power, it keeps rebooting every about 180seconds.
I don't have a PC with RS232 port so I bought a USB to RS232(DB9) with a chip CH340, but it seems didn't work.
I have two notebook computers. I tried netinstall, by holding the reset button and plug the power, about 30 seconds after, my routerboard shows in the netinstaller.
I click it, in the router/drives frame, and the packages frame turns to blank. no package there.
So I thought I maybe downloaded the wrong npk file. I opened the website and downloaded all the packages for all the platforms.
this time the netinstaller shows a package, the routeros-smips.
well, maybe my RB435G is a fake board, otherwise why it only shows the smips package in the netinstaller?
so I click the routeros-smips and click install, it stop at Formatting Harddrive...
I tried Netinstall v6.42 v6.40, all same, only shows the smips packages.
If use Netinstall v5.27 or v4.17, after clicked the rb435g, the application shows the MIPSBE packages, which I think is correct. but after choose one and click install, it stop at Formatting Harddrive.
I use only the cat6 cable to connect the routerboard and my computer, without a rs232 cable. I am not sure if the rs232 is the key?
any help would be appreciate.
