Hi,
You have a little mistake. in subsection 7 you wrote “7.after booting you will get a warning , press volume down and skip it. you will see a big android icon ,it shows Download mode
” you should press the “volume up” in order to skip. (not down).
thanks for suggestion , while writing articles it is very difficult to remember
your suggestion are always welcome
Trying to do this one, but everytime I apply the install, CWM starts to update but suddenly it stops and says “Installation aborted”? what can it be?
Will this work if you install the KG1 2.3.4 firmware directly from Kies 2.0? Im asking because you state KG2 above “congratulations your phone running on Gingerbread 2.3.4 XXKG2 is now rooted successfully”
Successfully rooted, thank you
hello.. I did this and I go to settings-> about phone -> android version says 2.3.3 but Kernel version says XXXKG2. Did I do this correctly?
Cant say but can you tell me , do you get a new app called superuser. if yes then it is rooted
Go to android market and install root checker app to check your phone is rooted or not
It is rooted for sure because I can use Superuser and Titanium back up. I just want to know if I have update to Android version 2.3.4. I thought the XXKG2 was android version 2.3.4. The Kernel version says ” 2.6.35.7-I9100XXKG2-CL375027 se.infra@SEI-21 #2″ but it says it is Android version 2.3.3.
Dont worry , root with latest cf-root
how do i put my phone in download mode?
