Anyone realize better battery life on this DZKJ2?

With unrooted : I have light use with some gmail and friendcast/ web check and SMS and a few mins of angry birds and after 17 hours battery drop only 28%. I have data and background services on.

I cant find complete changelog info which is credible for this 2.3.6 .Anyone seeing better battery life?

if u read a few posts above, I used both Kies and ODIN. I used kies to update first, then tried to root it, can root laa with the previous chinese kernel, it start up with yellow triangle.

But no stock kernel of this KJ2 ma... so i tried to make one by extract the zImage from stock firmware... but flash with ODIN tak jadi... connection ODIN to phone just stall while flash. I cabut wire and get phone/pc connection error logo. Then I used ODIN to flash back the stock firmware KJ2. Now back to normal. No root.

Still searching for this kernel for KJ2... I read everywhere there is all kind of info about extract kernel ( zImage) from stock firmware, but mostly many point to need to repack and I see tonnes of sites talking about using linux type commands. Haiyo too much to understand in one day. maybe in future , not today cause I am busy.

Just hoping someone else made a stock kernel for this KJ2. So far what I observe is battery life is better a bit ( need more data) and the homescreen got loop around back from back to front . Also some blue shade when u reach the edge of the area in applications and u still try to "pull" with ur fingers. Like "bounce" effect but not physical bounce , just blue shade. I didnt notice this in previous firmware.

Cross finger and hope for kernel.

Need some advice bro. I pulled the firmware from xda ( i think u the one who put up the link to multiupload).
I used Kies to update my firmware, then using the file from multiupload, I extract the zImage and made into a .tar. I flash with the previous rooted kernel...ok... have yellow triange... but when i flash again with the kernel built from extracted zImage, Odin just sit there for some time and not responding, its checking file and nothing happen. So I yank out the cable and after that I get a logo with a phone and pc and says not connecting..... use USB jig also dont go away...

So i put back your multiupload file, and then pit files and I flash again even though got that logo above, success, it come back alive...

Not sure if extract zImage and making a .tar archive from it is right way to do this. I inspect previous stock kernel, its just a rebuild from zImage extract from the K1 firmware. What possibly u think I miss out?

Waa pun pening lo... maybe something fundamental I miss...sorry I am very noob to Android, just 3 weeks.
Anyway here is the kernel file i made...donno if its of use for inspection ..

Any advice is highly appreciated. If its you the same person in xda too, salute. thumbup.gif

the homescreen got looping can be removed if you root with mygkernelv0_cwm5.tar (DZKJ1 insecure kernel with CWM)

You can use the older 2.3.5 insecure kernel and use it while waiting for a new 2.3.6 insecure kernel being built.

With this mygkernelv0_cvm5.tar , does the wi-fi work?
So it means we just flash this kernel on top of the pre existing KJ2 and we have yellow triangle at startup and everything works well? The yellow triangle of course we remove with the USB jig, right?

You can flash official KJ2 firmware but you will lose your root. After flash KJ2 firmware., you flash back the KJ1 insecure kernel again to gain back your root and CWM.
Use the link below to get root and CWM

after reading all ur guys post i think i'll keep using DZKI1+root for the time being at least untill a proper root+kernel and stock kernel for KJ2 pops out in the net... biggrin.gif

@waveweaver does it really work using that MyGkernel meaning root and cwm is installed after flashing it? so the only thing left is the stock kernel la for removing the yellow triangle but for now none is it

If you're getting a new bootloader then the jig wont work. It only work on the old bootloader. But why should you worry about the yellow triangle? You see it only on the start up :-) .
Another way is to extract and flash the ZImage though i never done it since i sold my SGSII already.

wifi should work properly if you flash official KJ2 full firmware then flash KJ1 insecure kernel :-)

If you have CWM then do a Nandroid backup for your current firmware. Use Titanium Backup to backup all you apps and use SMS Backup and Restore app to backup all you sms. All of this only as a precaution incase shit happen.

If that the case, you shouldn't ask whether the new firmware gonna be wipe or non-wipe :-P
