Guys, my problem solved with the IMEI. This is what I tried:

1. Terminal emulator - manual restore efs (failed)
2. Followed the guide on XDA on delete and rename a few files in the backup (failed)
3. Restore CWM backup (of course it failed)
4. Full wipe via CWM and try redo everything (failed)

The last try was done because I have efs backup (tons of them) but ktool or any other program can't read them for some weird reason:
1. Full wipe using CWM
2. Factory wipe (even with usb storage but efs backup move them to laptop)
3. Put in efs backup and install any other rom to install terminal emulator
4. Follow the method to restore efs backup on 1st page post #6 by uncle benny
5. Walaa~ Magic

Now, IMEI should be restored and PLEASE, backup using ktool again!

I want to thank all who helped along (too many to name so you know who I meant)...THANKS!

Thanks guys. Appreciate that lo.

Now waiting and checking if my efs are done correctly. Hahaha

Still wondering siyah or neak kernel are better for battery saving. Both when tested looks good. Hmm!

Been using my JABRA BT2045 since the first time I bought the phone.
Very good. Never had problem using it. Setting it is also a breeze

Gratz ur efs managed to restore, sorry bo help as I no gud in this efs thing, only know how backup n restore in ktool only

I would say both siyah and near kernel are very similar.  Only difference is that siyah kernel is mostly stock value and you need to tweak it to get a good experience while neak kernel had already been tweak.

So if u like to play and set the value yourself go with siyah or if u like a kernel that you can just flash and use then pick neak.

Lol. Seriously though the amount used during standby is not important for me.  It's the amount of battery used when screen on.  Cos on my type of usage I need to charge the phone 1 to 2 times a day. So standby time makes little difference for me. I use the phone too much. 

in-ear type?clip type? 

i think can sangkut at behind ear..

my budget around rm100.. 

u pakai tudung right? 

what is the difference betweem G and non G version?
