[Galaxy S Advance I9070 General] #Henkate:
Hi guys! I searched how to boot in safe mode on our galaxy s advance and i dont found any topic like this.If exist one and i dont saw it,please delete this thread.

Im on cm and yesterday i tried option "Simulate secondary displays",because i was curious to see what it does.I touched this option,then i choosed a resolution ( 720x480 mdpi) from there.Then my phone rebooting and while charging bootanimation,bootanimation stopped ( was freeze ) and every reboot bootanimation still freeze.Now,i still dont know for what is this option,but i advise you to dont choose it,let it "none" to avoid bootanimation freeze.I had like 300-400 mb data for internet browser ( lol :D ) and others apps and i dont had a backup.But,i did a backup after i got bootanimation freeze and then clear data and cache and then restore just data,but got again bootanimation freeze,so will wont work.

If you choosed this option like me and you are searching how to solve this problem without lose anything,you must go in SAFE MODE.

What is Safe Mode ?

Safe mode is a great tool that you can use to troubleshoot these issues. Safe mode boots your phone running only the apps that came with the phone – that means no third-party apps. Therefore, if your phone runs without an issue when you’re in safe mode, it’s a pretty good bet that the problem isn’t system related, and instead a third party app you downloaded.

After i tried some combinations and searched on google how to boot in safe mode in others phones,i got one working for our galaxy s advance (i think work too for GT-I9070P ).

How to boot in safe mode:

1.Power off your phone.

2.Reboot your phone.

3.When you see bootanimation keep pressed menu button ( left bottom button ) until your phone boot.When your phone booted,you should see a “Safe Mode” watermark at the bottom left of the screen, to let you know that you are in fact in safe mode.

How to solve same problem which i had:

1.Power off your phone.

2.Reboot your phone.

3.When you see bootanimation keep pressed menu button ( left bottom button ) until your phone boot.When your phone booted,you should see a “Safe Mode” watermark at the bottom left of the screen, to let you know that you are in fact in safe mode.

4.Go to Settings > Developer options > Simulate seconday displays and choose "None".Then close settings.

5.Reboot your phone and wait until your phone boot.

Alternate method: If still dont work ( i think is impossible to not work ) follow these steps:

1.Make a full backup (you can make full backup if you stuck at bootanimation).

2.Flash cm again.

3.Reboot phone.

4.Power off phone.

5.Go to recovery and restore just data from backup (advanced restore).

6.Reboot (at this stage i was stuck at bootanimation again,i think you too).

7.Now do steps from How to.

Now,maybe you will have some lags (like me,is not caused by safe mode),just install some scripts,like Pure Performance script (work for our phone,tested by me) or any others scripts/tweaks.

I done alternate method because i was too scared after i got bootanimation freeze :D instead go to safe mode before do backup.Just follow first method (instead alternate method),must work.

Maybe safe mode will work too when you get bootloop after flashing something over a rom,so you will can boot in safe mode and delete what you flashed,im not sure if will work (i dont tried),but is better to make a backup when you consider that you have something important to avoid all problems.

In my case,i dont had a backup before to change "Simulate secondary displays" option,and safe mode was solution.

Before finish this thread,im sorry for my bad english :D Good luck !
