    if I hard reset my gt-i9192 phone it don’t ask me to give network unlock pin again.

    I’ve gone through the procedure

    UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF >

    But
    When I am @ [6] Network Lock > Options there is only [1] option & no remaining Two options

    how can I overcome from this ?

    My Phone details are:

    Samsung Galaxy S4 mini
    Android: 4.4.2
    Baseband Ver. I9192UBUCNG1

  6. Hi guys,

    I own a gt-i9192 s4 mini and whenever i want to use the gsm/wcdma option it begins to restart by itself over and over and over. I´ve tried everything, including the upgrade to kitkat and still nothing.

    I´ve come to the conclusion that it may be a hardware malfunction.

    Is there anyone, gt-i9192 owners, from any place BUT the US, struggling whis this same issue.?

    Please let me know if there is a solution.

    Reply
    • Hi, maybe other member can give their same experience problems. However, we give you several steps to try, first you can try to change the WCDMA/GSM options from dialpad by press: *#*#4636#*#* Then you will see: Phone info, then choose at near bottom drop down options, choose one by one either WCDMA preferred or GSM Only or WCDMA only. If your Samsung Galaxy S4 Mini still auto reboot after choose that, then you have to consider doing hard reset or reformat to factory default, and try again above steps to choose Phone info from dialpad.

  9. Hii can you tell me how to restore system app in Samsung Galaxy S4 Mini i9192
    Particularly keyboard app
    It’s greyed out i dnt find any solution to this…
    Does soft reset will delete all apps in fone.?
    Is there any way to restore dat app through super user or titanium backup pro…
    I tried Titanium already but no luck

    Reply
    • Hi, first soft reset or reboot will not delete any important data and will not remove installed applications. You can use Titanium backup to restore all backed up files include system files if your phone has already rooted. However, we are not recommended to do root because sometime the standard solutions can not help your trouble. Let’s assume your phone still at standard conditions, than you have to try remove data and cache file at your keyboard applications from menu Setting > Apps > All > find your keyboard application, and after that please press Delete Data or Delete cache button. If you still can not fix this, please consider to try doing hard reset or reformat.
