Done flashing CF, now proceeding with SpeedMod, btw got yellow triangle, but I don't really care so yeah, I try now.

EDIT : Alright done flashing, feels like phone gone faster abit. 

hi guys. my sgs2 out of a sudden cannot connect to my home wifi already.

it keep connecting disconnecting.

reset router. reboot phone and no use.

help !!

i also just leave the yellow triangle dont care it
so that easier for me to flash new kernel or rom anytime anywhere
just hook up my pendrive and copy kernel or rom to phone then can start flashing on the spot

Guys my sgs non g is running on android 2.3.3 .

Hw can i update it to 2.3.5 ? Thanks!

Find a stock rom and flash it with odin or flash a custom rom.
Official stock rom for non-g version still stuck at 2.3.3 .

You can find official firmware here:

Follow the guide provided in the links.

2.3.3 is so much problem..phone crash , lag and battery very weak.

Added on November 11, 2011, 1:23 amthe link is confusing...

can i download it like apple do?

download and auto update...

in KIES of course..

beg to differ, fr my personal experience, wifi use very little juice (less consuming than edge)...i m always on wifi so im sure i dont get very far from the real result. i think the more battery killing is 3G. even edge is far juice saving than 3G. i think his wifi consuming cuz screen time when browsing or gaming

my daily usage for 3 months have been consistently 3-4hrs screen time , 1+ hrs calling, bluetooth connecting to jabra,, edge or wifi whole day...and still got battery about 10-30% end of day. if wifi n edge on overnight, barely drop more than 5%. partly my house wifi very strong otherwise ur phone will work harder locating wifi signal at all time that would consume alot battery, same like phone signal weak compare to strong signal, dfferent impact on battery.

if use 3G, wont last till dinner time (from full charge lastnight before to bed )

just sharing

No you cannot. Because this 2.3.5 is not official for Malaysia set.
Here easy step:
1. Download http://www.multiupload.com/SKUPDRAOKL (2.3.5 XXKI4)
    Get Odin v1.85 from here: http://www.multiupload.com/1RTGSE061G
2. Extract the .tar file in the archive(ONLY EXTRACT ARCHIEVE, DONT EXTRACT TAR FILE)
3. Go to download mode. To get download mode shut down the device. After it shuts off completely simultaneously press the Down volume key+ Home button + press the power button
4.You should see a warning asking you to press volume up if you want to continue or volume down to cancel, press volume up. You are now in download mode!
5. Start odin (DO NOT CHANGE ANY SETTING)
6. Click on the PDA button and browse to the .tar file that you extracted in step 2
7. Connect the USB cable and wait for the ID:COM section to turn yellow
8. Click start to flash
9. Do not disconnect the cable or turn off the device, it will reboot when it finishes.
10. Done
