Android Flash ROM

When flash a ROM, not simply delete/format the system folder (/system). it content all ROM/OS file, once delete it you can not access the OS.
How if accidentally deleted it when flashing a ROM.

1) Flash the ROM as normal flow. but most of time you are delete those ROM.zip file as well. then can go for second step.
2) Flash the ROM from ext-sdcard (memory stick). copy the file(ROM.zip) to ext-sdcard and flash the new ROM. but how if the file is not there and can not copy to there at that moment.
3)  adb command.
- go to recovery mode.
- command sample to copy the file (ROM.zip) to sdcard.
adb push D:\4\SuperNexus-3.0-i9500-BUILD1.zip /sdcard/0/SuperNexus-3.0-i9500-BUILD1.zip
adb push D:\4\gapps-jb-20130813-signed.zip /sdcard/0/gapps-jb-20130813-signed.zip
4) Try install sideload.

You can always backup the file to sdcard first.
** base on CWM recovery mode.

Permission problem

When Try Qwinsta to Windows Server 2008 R2, it Give error 5. Which not happen to others server.
After some Study, Can try the command below.

Psexec.exe \\123.123.123.123 qwinsta

OR

runas /netonly /user:administrator "qwinsta /server:123.123.123.123" 
* which will prompt for the server password.

And Windows Server 2008 not allow to remote to physical console anymore, no wonder how u connect it will not connect to session 0 (which reservce for service used).
But for your infor, for some of the purpose, you might need to use /admin (or /console) for the connection.
