Remember to take screenshot of the winning SR# while you play the Microsoft Rewards point's Flip and Win

Microsoft Rewards point's Flip and Win will never email you the winning SR# to your email.
So, you HAVE TO take screen shot of it or write it down before you close the winning page!!!
I won the "1 million sweepstakes entries for 1 million points"  on April 26, 2017 and thought that I will getting the winner notification email from Microsoft, but it never came in my email box.
MS customer service won't help unless you have the SR#.
So, for your future reference, the screen shot of the PR# page is very important.

PS3 CFW 3.55 kmeaw upgrade to Rebug scare experience! brick?!

I thought my PS3 game console was bricked after PS3UPDAT.PUP from 3.55 kmeaw to REBUG 4.30.2 REX. The brick symptom is when pressed power button, it will power on for 5 second then turn off right away.
Q: Tried out recovery mode method, but unable to get to the mode! Panic panic panic, brick?
A: No, it is able to get into recovery mode after swapped HDD from 320GB to 500GB. (Good news!!!)
Luckily, I did backup by using PS3 backup utility before doing software upgrade.
   Make sure you have the REBUG 4.30.2's PS3UPDAT.PUP on FAT32 thumbdrive root \PS3\UPDATE\ folder for the PS3 System Update/Recovery/HDD upgrade procedure.
   The PS3 restore is working on REBUG latest version 4.81.2, but trophy since I didn't sync it.
My PS3UPDAT.PUP upgrade route: 3.55 kmeaw > REBUG 4.30.2 REX > REBUG 4.46.1 REX >  REBUG 4.78.2 REX >  REBUG 4.81.2 REX.
(Not sure if you can upgrade it from 4.30.2 to last version(4.81.2) right away?)

FTP by using REBUG ToolBox is better than using it from Multiman.
Please use AOMei partition tool to convert FAT32 to NTFS for the backup HDD since file sized over 4GB won't able to save on FAT32. Just FYI.

Press Ctrl-Alt-T to open Terminal
Ubuntu$cd Desktop
Ubuntu~/Desktop$cd fog_1.3.5
Ubuntu~/Desktop/fog_1.3.5$tar -zxvf fog_1.3.5.tar.gz
Ubuntu~/Desktop/fog_1.3.5$cd bin
Ubuntu~/Desktop/fog_1.3.5/bin$sudo ./

Database is invalid

Ubuntu~/Desktop/fog_1.3.5/bin$cd /var/www/html/fog/lib/fog/
Ubuntu~/var/www/html/fog/lib/fog$sudo nano config.class.php

input database password for the define ('DATABASE_password', "passsword4DB_here");

Click on "update" button on the fog portal.
Upgrade is completed.
Error#1: PXE-E51: No DHCP or proxyDHCP offers were received after upgrade fog server.
The output of your /var/log/syslog, after you attempt to start the dchp server
Look like upgrade process removed modified the DHCP server .conf on Ubuntu!!!
Have to update the /etc/dhcp/dhcpd.conf with correct IP range from subnet to etc.

sudo apt-get install isc-dhcp-server

sudo nano /etc/default/isc-dhcp-server

sudo nano /etc/dhcp/dhcpd.conf
default-lease-time 600;
max-lease-time 7200;
option subnet-mask;
option broadcast-address;
option routers;
option domain-name-servers,;
option domain-name "mydomain.example";
subnet netmask {
filename "undionly.kkpxe";

sudo service isc-dhcp-server restart
sudo netstat -uap

To check "eth1" INTERFACE:
sudo nano /etc/network/interfaces


Sounds like the dhcp server isn't running properly or the tftp server.

Restart TFTP
sudo stop tftpd-hpa
sudo start tftpd-hpa

Restart DHCP
sudo /etc/init.d/isc-dhcp-server stop
sudo /etc/init.d/isc-dhcp-server stop

"Fn"-P to pause boot up screen

Setup the HD IP POE camera

Purchased it from during 11.11, got it 20days later since ordered.
Its default IP is (See the screenshot from the item page, took me awhile to figure it out).
So, you have to set your PC with IP: and connect it to a POE switch alone with the IP POE camera. Install the CMS software from the tiny CD media that delivered with the item box to PC. Follow those steps with screen shot on item's page to "ADD DEVICE" -> "Remote Config" the IP Camera -> "Setting" -> "Network" -> change it from fixed IP: to DHCP -> Save and Reboot the IP camera.

URL: item Bullet-IP-Camera-3MP HD-1080P-POE
Check your router DHCP Monitor for the IP that camera is assigned, reserve the IP.
Add the DHCP IP to your surveillance system by using ONVIF with port 8899.

Internet and Voice service with Xfinity aka.

Rental Cable Modem TM722G for voice service(Land line) charges $10 per month.
Purchased Arris TG862G Cable Modem and return the TM722G to Xfinity service center at Westgate mall to remove the $10 rental to save money.
   Have to ask the pre-owner of the TG862G to call 800-934-6489 Xfinity tech support to cancel account that associated with the TG862G Cable Modem. Otherwise, Xfinity was refused to add the Cable Modem to my home network/voice service account.
   Internet setup is easy for Cable Modem, but the Voice. You have to make 2 tech support call for them.
   The Voice service have to use L1 and it is using EMAC aka. MTA-MAC. Have to wait 24 hours to be working after set the EMAC up from Xfinity server. (The Xfinity tech support technician is not knowing the fact. So surprised of it!).
    I have to set the TG862G as "bridge" mode to cooperate with Fortigate FWF60CM router. The WAN1 with DHCP from Xfinity will work with the "bridge" mode with DHCP disabled.
    Note: There are 4 LAN CAT5 jacks on TG862G, if you have LAN1 to WAN1 and the PC is connected to one of the LAN2~LAN4 with DHCP, then Fortigate FWF60CM router will have no internet connection then!!!
    The WiFi on TG862G has no internet connection even it is enabled, so just disabled it.
    To reset Cable Modem have to press and hold the reset button for 10 second. Its logon user name is "admin". Its default password is "password". Its URL portal is at You have to set a laptop PC with fixed IP to and connect the LAN1~LAN4 port on Cable Modem.
Somehow, the URL portal is changed to after Xfinity  reboot my Cable Modem and updated their firmware or something?!
