Hi guys

root@antMiner:~# cdusr/bin
root@antMiner:/usr/bin# mv cgminer cgminer.bak

any help would be great cheers

You forgot to set cgminer as executable.   Type "chmod +xusr/bin/cgminer".  That should do it.

You just missed a step is all. Step 4 below.  After you use wget to download cgminer, you have to change the permissions to allow execute.  The permission denied error is because there is no permission to execute the command. 

   1. cdusr/bin
   2. mv cgminer cgminer.bak
   3. wget http://ck.kolivas.org/apps/cgminer/antminer/s3/4.6.0-140908/cgminer
   4. chmod +x cgminer
   5. Reboot

no need to reboot the device
/etc/init.d/cgminer restart
 or
/etc/init.d/cgminer stop
/etc/init.d/cgminer start

rebooting gains you nothing except not understanding what you are doing.
all u r doing in this process is replacing a single file that is presently running, so simply telling it to stop the old one and start the new one is all that is needed... u r not changing or modifying anything OS related to need a reboot.
  just like u dont need to reboot when changing frequency...

Couple things.

1.  The steps were already provided, so I copied as a convenience.
2.  The reboot may not be necessary, but is also a convenience that does not hurt, and it ensures a clean restart.
3.  You have a typo.  The command isetc/init.d/cgminer.
4.  I think the comment of "not understanding what you are doing" was not necessary.  The info can be provided without put-downs.

what is being lost is understanding what you are doing.
there is no reason to reboot and the reboot step was added simple because someone didnt know how to properly cycle something in unix.

do you reboot when you download a browser? do you reboot when you add a plugin to your browser? do u reboot when you install candy crush?

I certainly would reboot if I installed any of the above on an openwrt system (pertinently the one on S1 and S3 rigs) with nothing near the resources of the typical *nix box you are accustomed to.
Now for my question: Do you reboot your antminer rigs every so often (unlike the typical *nix boxes that can run for years un-rebooted) and why?

EDIT: - And if you REALLY think about it, we are talking about rebooting when you install the less resource wasting cgminer as witnessed by the improved UI response (and of-course the securiy patches). The point was, rebooting does NOT cost you a thing, and may indeed be beneficial since you still need to reboot the rig every so often.

I ordered 42 antminers S3. But 4 are not properly (1 half speed, the rest even worse). Offcourse I submitted a 'ticket' to webmaster@bitm... with all order numbers etc., a few days ago, but not an answer..? In the pre-sale fase they answered within 3 hours, but when seeking support they are 'busy'. Does anyone else encounter this problem? If yes. The pre-order scam is over and we got a new scam starting here..

It is likely nobody has been around to respond to messages for the past few days, as there is a public holiday festival right now - National Day, October 1 - 7.
