No problem, you said backup, yes, it's a good idea to do backup, if anything happened, just do the restore, no need to re-flash back

For backup, I'd prefer xRecovery, here http://forum.xda-developers.com/showthread.php?t=878426
The installation seems to be easy to follow.


To activate

It's better to test 1st whether it's working or not


How To JIT: http://forum.xda-developers.com/showthread.php?t=877565 (I'll explain again with picture )

1) Download JIT http://bit.ly/JiT-toggle

2) Open CMD (Command Prompt) and change directory adb folder. Type this command

the file build.prop being pulled out to the folder, as below: make 2 copies of the build.prop file, 1 is original, 1 is modified



3) Open the file build.prop with notepad. Modify it as below
Change
dalvik.vm.heapsize=30m
debug.sf.hw=1

add this at the end:
dalvik.vm.execution-mode=int:jit
save the file.



4) Extract and Copy JiT-toggle-0.1 folder to the SDcard.


5) Inside JiT-toggle-0.1 folder, copy & overwrite original build.prop to vmlibs_stock. Copy & Overwrite modified build.prop to vmlibsv2
picture below



6) Next, type

then

important: check your phone, superuser request will pop out once you type su, allow it. In case it's not pop out, manually go to superuser, and allow it. Otherwise you'll get permission denied.


7) Type

important: in your phone, Turn off USB storage (unmount). Otherwise you'll get error can't cd to sdcard/JiT-toggle-0.1


8) Type

your phone will reboot and you'll have jit enabled

Below is the picture

Feel free to modify, in case I forgot anything

p/s: Remember to install xrecovery 1st, sediakan payung sebelum hujan

Sos, I did use this method. But I feel it affect some part of x8 performance. So I decide to disable it. Restart and freeze at se logo. Unlucky, I have no backup. Reflash all over again.

I don't know maybe I made some mistake somewhere. Anybody with success story perhaps can share his.

*type this using x8 and it not that easy...

Just bought myself an X8 and got them to upgrade it to Android 2.1. Very good phone for the budget, let's see if any probs start cropping out down the line.

This method works but better to backup if it goes wrong. When disabling the jit, yes, it will hang the phone. enable jit again then it's ok. I just leave it enable anyway, so far no issue

can x8 use bluetooth after update to 2.1?

Just got my X8 yesterday Still playing around with it. Is there any GPS like Garmin for android?

Get papago. Quite good for android. I will install on my X8 once I upgrade the memory card this month.

Yes and No. There is Garmin for Android but only exclusively for Garmin Android phone. Use Papago X5 as I think it has the best map from malfreemap so far.

Thanks! Will look for it now. By the way, anybody use the program that can detect speed trap? I think it's called trapster.

Yes will malfree map update but it is just POI with regular speed trap area.
Now with the new speed trap gun, more portable they can easily change location.
For me this function is useless.

I see i see, police wont stay at the same spot most of the time.

I need to buy Papago X5 right?

guys...x8 performance good or not??

good after root + JIT
better alternative, get LauncherPro or ADW app
stock interface = lag


here something to share wif u all

so far my phone takde hal

Feel like want to JIT my phone, but it's only 1 day old, warranty void then all gone

initially thot the same too, but then beh tahan the sluggishness
apparently SEUS is a life saver. i flash my phone dono how many times edi.

My hand is getting itchy to root and JIT it

By the way, I'm going to purchase papago x5 soon, but from the web there's no xperia as compatible phone model, will it work? and also the package come with a micro sd card, have to use that or we just need to activation code?

papago x5 does not work with current x8 rooted 2.1... try sygic aura instead...

hi every1, i'm a new x8 user for 2 days only. i wanted to download dr.web antivirus n angry bird but the download couldnt run, what i can see is only "start download". i've tried 3G n wifi but the same problem persists. is any1 out there facing the same problem? i've yet to upgrade to 2.1 n was wondering does that affect the process of downloading? suggestions, comments n solutions are appreciated

Hi, when I run the last step, enable_jit.sh, The command prompt show cannot find busybox but my busybox in the sdcard root and accessible by titanium backup too

Here, use my version of busybox

Copy the busybox to system/bin in your phone, not sdcard
