Thanks a lot for the guide line. Will try later.

After I install all the apps, I face once SOD when optimized backlight tick. So I un-tick already, till now ok... except tat stupid stuck during boot-up still there.

The optimized backlight I do prefer off as it actually deem more the brightness, so is ok for me to off.

Now the only issue is that stuck during boot-up.

I also repair before, but using PC Companion. At beginning I never stuck and this and that.

But after I install all apps I want (I download from play store, not from backup restore) I face that two issue lo.

I believe PC Companion and Update Service is same.

I never use any FTF before.

Step I did

• Root using vRoot at .475 firmware.
• Change CDA at build.prop to Taiwan base.
• Connect to PC, PC Companion prompt new firmware found.
• Update via PC Companion to .510
• Repair my phone via PC Companion to beginning as flash.
• Didn't do any root after that.
• I switch off the optimize backlight as I never like it.
• Everything run perfectly fine.... until.................... after a long install this and that............ when I switch on the phone from off - that faking stuck appear.
• Then I hand itchy, I go switch on the optimize backlight to hope maybe can get away fake stuck.
• Lock my screen, and "tada".... 1st time happen SOD to me.
• Restart the phone by take out the SIM Card, and turn of the optimize backlight.
• So far so good now, not sure fake stuck will happen again or not as I haven't switch off my phone yet.

Later I may root... now lazy to update service repair...

Ya, it is and I hate it.

Hmmm... I think I gonna to do another repair. This time try Update Service.

Now the phone after restart is SOD nor-matter I off the optimize backlight or not.

Some said backup restore got problem, not sure is the problem from Android backup or not as I do let that one auto restore.

After you did restore via US, do you still face that fake dead at startup?

I notice the fake dead is related with SOD.

I think I root 1st then factory reset see how... hmmm... and don't restore setting from Android auto backup.

I am superb pretty sure that Taiwan kernel got problem~

The phone don't have stuck issue when I switch to Hong Kong kernel post by Benny888 for vroot to root my phone.

After success root, I use thatisazam method to make Chainfire SuperSU as default and remove that Chinese SuperSU. Successful as well.

Then when I restore the stupid Taiwan kernel, the stupid fake hang issue appear back! OMG!

Thanks a lot Benny888 & thatisazam of the guide.

But my phone still stupidly hang.... the SOD still appear... now gonna backup everything 1st before restore again using Update Services see how.

During use Hong Kong kernel, I notice it not support exFAT 64GB card but the latest stupid Taiwan kernel support it.

Thanks for reconfirm. I need backup 1st before do again.

Tak boleh tahan already the hanging issue.

Before that I don't have any issue, then it just sudden appear, also no idea is that because of apps I install. I suspect is Remote RDP as I notice seems is that one make my phone alarm icon keep missing at status bar after a while. Now gonna do it without install that. See how.

My Xperia is failure to start when use Hong Kong kernel and also not support 64GB exFAT card. Or else I will decide keep that Hong Kong kernel.

I try factory reset also not working. Working fine until shutdown... then bye bye.

Now gonna try repair using Update Service see how.

Downloading... and please be ok.

Hi, now I am repairing using Update Service (the firmware re-download now) instead of PC Companion.

Now I got a question, did you use the Benny888 post method? Downgrade to HK kernel and then root and then restore back using the provide Taiwan kernel.

Any issue like SOD or Fake hang after doing it?

I found the reason why the phone fake dead or SOD already!

I follow h11g re-repair my phone using Updates Service, everything run perfectly until I go un-tick the "Optimize Backlight".

Once you un-tick this thing, the phone will behave fake dead when startup the phone after switch off.

Don't ever un-tick "Optimize Backlight".

What I did later is immediate tick back the Optimize Backlight after success login to the phone and shutdown.

After that, I try switching on and off few times, and it behave normal, no fake dead & SOD.

Ya, finally but with optimize backlight, the color had change especially the black as the black is not over pure black. Seems more accurate color but a bit dull.

Now I find safer way to use without
optimize backlight. Just make sure tick back before shutdown.

Must tick before shutdown.

Use wise, tick or unstick base on user preference.

Can you try something, go to display and then un-tick optimize backlight, after that shutdown your phone and restart the phone.

Let me know whether happen fake hang or not.

If happen then just wait until it load in, then after that go back to display and tick back the Optimize Backlight and immediate shut down.

The phone will behave normal back in your next restart the phone.

Yes. same bugs.

Wait until login. Now immediate goto display and tick back the Optimize Backlight and shutdown the phone.

In your next startup the phone, the fake hang issue will not happen and you can decide want to use optimize backlight or not.

But, just make sure you must tick back the Optimize Backlight before you plan to switch off the phone again.


Conclusion is there is no fake hang when the Optimize Backlight is turned on before you shut down.

The SOD after lock the screen won't happen if your startup never face fake hang.
