• THANK 4 SAVE ME AND MY GADGET.........

• every time i try to do this the phone just starts normaly

  • Do it for several time with that button combinations. Or when you still can go to menu or while LCD screen still can be respond your touch, then doing hard reset with software menu is more easy.

• Hi,

  I am trying to hard reset my SII but option 2 and 3 are not working. I forgot the password for my phone so when I try to do reset factory setting default password like 0000 or 1234 is not working

  Option 2 - it always turns on my phone and goes to the home screen
  Option 3 - it says supplementary data not available (or something like that)

  I need help. Shoot me an email for any other suggestion.

  Thanks a bunch.

  • Sometime you have to do carefully for hard reset Samsung Galaxy SII when perform with hardware button

    • But when i choose the "yes erase all data..." It will ask me "confirm password" but i don't know what is the password. Pls help me

      • If SGS II ask for password when you need to hard reset with software menu, it mean you need to give the same password protection for screen lock. Let's try like this, turn off the SGS 2, after that turn it on again. When you want to use that Android, it will ask for screen lock password/pattern (that you've already gave before), then usually you type the answer to user it. That is exactly the same password which is ask when you want to do hard reset with software menu.

• Does the default operating system installed on the (System Storage) only or needs space on (USB Storage), i need to clean all old data as i feel not all data are deleted after Hard Reset, in other words what is the size of The clean default operating system ??
  thanks in advance

  • i'm asking about Android Version 4.1.2

  • SGS2 factory default operating system has already saved in SGS2 rom or internal memory, by default we can not access this files without special software, so the default and clean master of operating system will be reinstall automatically to Samsung Galaxy S2 (i9100) after doing hard reset or master format.

• thanks

• i do hard format more than one time before but the problem is still in my phone( swich off alone many time in a day)and (cannot read aflash memor when i conect with it) can you help me to solve these problem.

  • Hi, if you have already do the factory reset or hard format, the phone should run normally again with default setting. When you still get problem with switch off by itself, I think maybe can be happen because several issue.

    First, maybe about the applications issue, there are some applications which reinstall again although you already format but you have backup applications at Android Google cloud backup, then it can be reinstall again and of course the phone will get problem again because the same incompatible applications is there.

    Second, maybe it is external memory problem, in some case we found that external microSD card can make problem for our smartphone, what you need to do is try to change or remove external memory to make sure about it.

• I try to hard reset with option 2 because I have forgot the password for screen lock. After I answer Yes to erase all data I am asked to confirm password. What password is this?

  • Hi, if you forgot the Samsung Galaxy S2 screen lock pattern, the only option that we suggest is doing hard reset with option two. As far as we know, SGS 2 will not ask password anymore while you do hard reset with hardware button. Please try it again carefully.

• I know my gmail user name and password, but can not get the lock screen to give me the "forgot password" option. I have incorrectly entered my pin 100 times and still there is no, forgot password option. How do I get that to come up?

  • Hi, for normal conditions, we can easily bypass the screen lock protection by pressing Forgot Password button. Usually if you've done several time wrong password answer, then that button will be appear because the Samsung Galaxy S2 phone will be frozen and tell us to wait several second before try to answer again. But this option maybe not always like this if you use some custom rom or any other tweak before. If you can not deal with the forget password button, maybe you may need to consider doing hard reset.

• i was resetting my sgs2 and my brother took out the battery. and nw the device is not working. only samsung is being displayed on the screen. is my phone screwed up..?? somebody plz help..

  • Hi, please try to do hard reset with hardware button, hopefully the phone will be back again after reformat the operating system.

• i tried all the steps on how 2 hard reset mysgs2 but the all the ..filleson internal sd is not formatted..and the problem is still theremy main problem is everytime i surf internet there is always security warnings appear i cant even open my facebook...wew..pls a little help...

  • Hi, usually after finish doing hard reset or master format, the Samsung Galaxy S2 will be start again from beginning like new, so we need to login with Google account or Gmail account, after that install some applications that we need to use. When doing hard reset, the internal memory will be reformat, maybe the external not formatted, except you force for erase all external data from Samsung Galaxy S2.
