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.

Upgrade fog from version 1.2.0 to 1.3.5

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
