How to update samsung galaxy tab p1000 i.e. 2.2 to 2.3. using ADB? I am updating the OS of my Samsung Galaxy tab p1000 (i.e. 2.2) to 2.3.6 using adb. 

I am using the steps below:


Check whether device is connected or not using ADB.  

C:\Users\PC&gt;adb devices 
List of devices attached S6802084d305f device

Push 2.3.6 OS (i.e. update.zip) OS to SD card.

C:\Users\PC&gt;adb push C:\Android\update.zip /sdcard/update.zip   
2765 KB/s (2260360 bytes in 0.798s)

Go to recovery mode 

C:\Users\PC&gt;adb reboot recovery





After selecting Apply sdcard: update.zip, I'm getting the screen below. But it shows it for long time. There is no response from device. We waited for 5 hours. No response. 



How can I flash my Samsung Galaxy tab? Let me know if I am missing a step.
These are the steps to install/update a custom ROM from stock:


Install a custom recovery (Clockworkmod for example).
Copy the ROM zip to the phone sdcard (you can do this via adb).
Reboot in recovery (it will load the custom recovery).
Use the option to install zip from sdcard to install/update the ROM.
