No

Yes. I guess the instructions never mention anything about rooting first before installing.

Wonder why the rooting guide is removed for XXJVK ROM at XDA??

I failed to root with FuguRoot... Now cannot start... The Fugu icons keep coming out, cannot boot...

What you guys use for rooting JVK ROM?

How to tar the zImage? Just rename right?

I extracted the zimage and rename to zImage-new.tar. Then flash after fugu root flash.. But still cannot boot..

I realized that the download bar never start, just straight away go to RESET, maybe that is why the ori zimage is not flashed and I can't reboot.

Ic. Get it now, I thought just extract it out from the PDA. No wonder doesn't work. Thanks bro...

Yea.

Gingerbread is really snappy and fast. It sets SGS to the way it should be in the first place.... Confirm wifi signal is lower than JS8. GPS is good and fast lock, camera works! So far so good, still testing the new ROM.

I leave the CSC at KOR and set APN manually. Next step is to get back CWM. Any custom kernel to recommend that is compatible with JVK ROM?

Strange. This morning I found that my APN is gone. Need to redo the process again. BatteryHistory app is not working anymore. I guess the secret codes has changed.

*#1234# is still working..



Batt just drop 3% overnight with wifi on. Running Gingerbread XXJVK ROM now!

around 7 hours +

I am impressed as well with the batt life. Yea, I miss the dark theme of android market and the dark transparent curtain of the notification area.



Locking bootloader is actually not a bad thing. It will help increase security considering many viruses are bound to surface in near future that can steal data and do serious damage to phone system. Yea, it is bad for custom ROMs and rooted apps since the early versions already give way to many innovation on this part. That is why I prefer the way Sony is moving in their future direction, which allows users the option to lock and unlock the bootloader in their xperia series.

On the other note, whether bootloader is locked or not, someone somewhere will figure a way to hack into it somehow. Just take an example of iOS.

I just found out Galaxy Tuner doesn't work in JVK ROM..

I face the same problem. silentser help me solve it. You can search back a few pages for guidance if you want to do it yourself or you can download from here:

Never thought of wiping before. I straight away flashed from Simply ROM. But I think it is advisable to wipe first so to have a clean install.

A short review of XXJVK aka "Leaked Offiical Gingerbread"

1. Fast and snappy. Feels like custom Froyo ROM but I don't feel it can beat custom Froyo (yet).
2. Experience quite a number of apps FC due to not very compatible with Gingerbread ROM yet I think. Will improve over time.
3. Swiping homescreen and app drawer generally are smooth, but sometimes do feel certain lag when I tried to swipe and some background tasks running at the same time (for eg. push email, scanning SD card, updating fb, etc)
4. GPS is very good, better than when I was on Simply ROM. Can lock fast and accurately (even without data on)
5. Wifi is fine, but the signal is lower compare to before, but this is probably due to the wifi signal is fine tune in Gingerbread to be more accurate.
6. Voice recognition improve greatly (I feel). Much more accurate now.
7. Battery life is good. Better I think.



8. New features in settings like the battery graph above.
9. Hardware accelerated browser. But Opera Mobile capability already exceed this.

Cannot work: spare parts, galaxy tuner.

Sometimes: Handcent SMS, Samsung Email, Widgetsoid.

The above are what I discovered so far.

Tested and OK: Waze, Angry birds series, Fruit ninja, ES File Manager, Whatsapp, Beluga, Facebook, Colorize Widget, NoLED, Opera Mobile, Plume, etc.

Yea. Restoring everything from Titanum Backup seems to be the problem. I restore apps+data and it seems that some old settings are not compatible with Gingerbread and cause the FCs.

Is it the early lags? means that when you want to use the phone the first time from screen off, you feel some jerks or lags swiping screens, opening apps, etc? But after 3 secs, everything is smooth again..

I think nexus s running on ext4 fs. SGS gingerbread is still on RFS fs. I like to blame on RFS for the lags....

Mind sharing the lagfix link?

Connect to internet thru data or wifi? If data internet not working, check your APN.
