Hi all,

Anyone can help?
I am trying to upgrade my Tab 7.7 from ICS to Jellybean, but my PC cannot detect my tab in download mode, but able to detect my tab in normal mode. It will show as Unknown device...

Any ideas?

I have tried to install the Samsung USB drivers, changed cable, but to no avail.

Appreciate any help.

Do one of the following:

1. Uninstall everything included with KIES. Clean your Windows' registry on your PC. Try CCleaner first. If not try one with a deep registry cleaning function. Reinstall KIES BEFORE plugging in your device again.

2. Choose another computer that has never had KIES installed before, and complete the (KIES) installation, run KIES all BEFORE plugging in your device.

Tried step 2, doesn't work.

try uninstalling the device from device manage in control panel -> system
then with the device in download mode, plug in to your pc, shut down the pc.
power up pc and let it goes into windows. check your device manager if the drivers are installed properly.

You can try using Odin to update. Follow the instructions here:

DroidViews | Update Samsung Galaxy Tab 7.7 GT-P6800 with Official Android 4.1.2 Jelly Bean Firmware

I want to use Odin, but the download mode doesn't work, how to update using Odin?

Search for "odin" in this thread: http://forums.hardwarezone.com.sg/t...tab-7-7]-thread-3481032-250.html#post76717825

There are links on the website which I posted detailing how to update. Basically you just download Odin, Samsung USB drivers and the required firmware then just follow details.

The thread that xonix recommends also has some good information especially this post
