Final command should be as follows

cp asic-freq.config /etc/asic-freq.config

"Step 1 Using Putty  or another program SSH into your Miner
Step 2 Click "YES" on the "Security Alert" that pops up
Step 3 Login with User: root Password: admin
Step 4 Type "cd /config"
Step 5 Type "vi asic-freq.config
Step 6 Hit the "I" key to edit the file
Step 7 Scroll the the bottom and copy this code and click in the SSH window to paste it (I suggest you start with the 212M Settings run it for a few hours make sure your miner is stable then work your way up)
    option 'freq_value'    '5082'  #212M
    option 'chip_freq'     '212.5'
    option 'timeout'       '36'

    #option 'freq_value'    '6206'  #216M
    #option 'chip_freq'     '215.625'
    #option 'timeout'       '37'

    #option 'freq_value'     '5102'  #219M
    #option 'chip_freq'      '218.75'
    #option 'timeout'        '38'

Step 8 be sure to add "#" in front of everything listed on the 196M line
Step 9 Hit "esc" then type ":wq"
Step 10 (IMPORTANT) type "cp asic-freq.config /etc/asic-freq.config"
IF YOU SKIP THIS STEP ALL SETTINGS WILL BE LOST WHEN YOU POWER CYCLE THE MINER
Step 11 Now Login to the web interface of your miner and go to the miner config tab and click "save and apply" this will restart cgminer with the new settings

Based on my testing here is how my miner performed at each speed

212mhz     1083GH     (+56 Watts)(+80GH Speed)(HW Error 0.22%)
216mhz     1098GH     (+71 Watts)(+95GH Speed)(HW Error 0.39%)
219mhz     1114GH     (+90 Watts)(+111GH Speed)(HW Error 0.88%)

everytime I reboot my s2... it reverts everything back to like I was upgrading firmware.... very irritating...

I edit the config file, reboot. and its back to normal...

anyone know how to stop it from doing this??

the admin password worked. thanks

oh. i'll try the admin ssh password

Try downloading the latest version from bitmain's site and re-flashing again. remember password for ssh is admin not root.

I upgraded the firmware on my s2. I can login to the web ui with my password, but cannot change the password in the web ui. it says password invalid.

cannot SSH into it either... password invalid. I tried all the firmware listen in GITHUB.

whats the damn problem??? I need to ssh into it.
