managed to update my SII thru Kies. took 2 hours+ to download the firmware using Digi BB.



here is what I did:

1) Windows 7 Pro 32 bit
2) Disabled Antivirus, Malwarebtye's
3) Turn on Flight Mode.
4) Fully charge S2 to 100%
5) Let Kies detect S2. then restart notebook. and let kies redetect S2.
6) Let Kies perform backup of S2.
7) Download firmware and wait...
8) Flash S2
9) Done
10) S2 reboot.
11) Disconnect cable from notebook

for those updated to KH2, do u notice GPS locking now is very slow?

I have tested using Yooboa Long March battery pack 2A output port to charge my unit, from around 35% to 100% take around 2.5 hours. It can full charge S2 up to 5 times max.

I also keep original charger in box. I'm using TAB third party charger with 5V 2.1A output to charge the S2. No problem.
