As usual I will share my particular experience in the hope of being useful to those in search of a solution or a simple explanation, ending up in some way to this blog! That is the subject of forums there are many but often, as happened to me, are too general and scattered compared to the case that interests us. For this reason immediately clear that the above has been tested specifically on a Nokia N78 brand TIM fw 12,046, while the procedure is valid and applicable to all devices Symbian S60 3rd, 3rd FP1, FP2 3rd and 5th Edition, brandizzati o meno che siano (per una lista completa dei dispositivi guarda in fondo a questo post).
 Per prima cosa occorre brevemente capire a cosa serve questo benedetto     hack    ! Detto in poche parole l'  hack   serve ad accedere a porzioni di   memoria   e del   filesystem   del cellulare, altrimenti inaccessibili (come cartelle e files di sistema). Una volta effettuato sarà poi possibile leggere e scrivere in queste zone protette in modo da   modificare  ,   patchare   o   crackare   (come meglio si voglia dire) tutti quei files che, per diverse esigenze, lo necessitano. Sarà ad esempio possibile disattivare, editando simply a file, a function of junk on this screen  StandBy ,   such as calendar entries or that annoying message "no news is not viewed  " dell'indesideratissima and inutilissima application  News Click  (who has a branded cell  Tim  know what I mean!). Another thing possible, and probably one that pushes all and most of all to make the hack, is to change the program assigned to install applications on your device, such  installserver  running on the phone, and normally does not allow 'installation of unsigned applications   or "unsigned". 
  clarified for big lines do you need a hack   jump straight to the facts! 
  There is a program called  HelloOX2 , arrived in early October to version 2.3   available at this address  , precisely allowing full access to the folders and system files. The program includes an internal tool called  ROMPatcher +  that allows you to apply patches   (either existing or personal fulfillment) on your mobile. The peculiarity of these patches   is not "definitive" but can be activated if necessary on the phone and remaining in effect only until the phone is turned off.  Questo consente di sperimentare nuove   patches   (o utilizzarne di esistenti)     senza il timore di causare problemi irreversibili sul proprio dispositivo. In particolare con   ROMPatcher+   incluso in   HelloOX2 v2.03   sono presenti già due utilissime   patches   pronte per essere semplicemente attivate:  
  -    Installserver_FP2   
 permette di installare sul proprio dispositivo tutte le applicazioni unsigned che si desidera
-        Open4All_RP+     
 permette di accedere alle cartelle protette di sistema
 L'applicazione   HelloOX2 v2.03  is made available on the official website of the author   in two versions: 
 -    signed  
 or already signed to be installed and used with your particular device, without any further rounds. In exchange for a donation is requested, be made by PayPal, the author.
-    unsigned  
 or not yet signed and that requires a valid certificate to be " signata " before installation.
 a rule, I encourage you to first choice (because, if nobody will help with some donation, the author certainly does not continue to issue updates in the future) but I would be hypocritical in doing so and then it would be too easy! 
  Instead, in choosing the second path, there should be a few more steps before you can install the application and then make the ' hack.  In particular, you certify the application  HelloOX2_v2.03.Unsigned.sis  using one of the procedures described in the previous post "How to certify   unsigned applications. 
  Once signed the application install it: During the installation process will be mapped to the system folders in virtual drives, copying files hacking needed virtual drive, enabled file system, a   mapped virtual drives, installed the root certificate installed and finally  ROMPatcher  + v2.2. 
  installation is complete it just started. In the screen that appears on the list you will see the two patches   discussed above:  Installserver_FP2  and  Open4All_RP + . Activate the first simply "clicking" and exit the program as well. If you're lucky you should already be able to install unsigned applications  , try! 
  If   patch does not however have the effect hoped for, turn it off (at same way as you have turned on) and consider one of these two alternatives: 
 -  searched in the forum (see links   at the end of post) a patch   's  installerserver  that is specific for your phone, or for your model and firmware version: you have to do is find a file type  installserver.rpm , copy the directory   patches, which  ROMPatcher +  have already created in your memory card  , restart the application, enable this new   patch (which will appear automatically in the list of patches   available) and see if it works (trying to install any unsigned application  ). 
 This solution, as well as the application of any patch , there is no risk and is always reversible: simply turn off the patch, or power cycle the phone, go back to business as usual. Try the patches, therefore, does not cost anything!
-  searched in the forum (see links   at the end of post) a version already patched   's  installerserver  that is specific to your phone, or for your model and firmware version: you have to do is to find a file type  installserver.exe , activate the patch      Open4All_RP +   , copy  directory c: \\ sys \\ bin  and see if it works (trying to install any unsigned application  ). 
 This solution, as well as any tampering with system files, always has a minimal risk, though in most cases (including this one), it is reversible: in fact, just delete the file you just copied back to business as usual (if you change or overwrite a file, however, always advisable to make a backup copy first, to be able to restore later if necessary).
 One detail that should be stressed is that the use of   patch is "not final" in the sense that every time you would like to install an unsigned   will need to activate the patch   by  ROMPatcher  + (a unless it is set in auto mode  , which means that is activated by one each time the phone) while editing or adding files between those systems is a modification of "definitive" in the sense that, less than do the reverse operation (when possible), is still up and running at every system reboot. If you then make a change that makes   system crash during boot   will no longer be possible to reverse the operation to restore the system in the stable configuration. For this reason, if you want to experience new hack   you should do so making a patch   rather than directly editing system files! The name of the program further clarifies the issue: all files that reside in   ROM can be patched  , at run-time, with this program. 
  For those who want to tweak in the system files or those who are forced, in the absence of a patch   for his mobile phone, to use the second solution, I suggest you download and install X-plore  , a file manager for mobile devices with many advanced features (including a hex editor) available as shareware    to this address . Obviously, in order to access system files will still be necessary to have carried out the 'hack  , as explained above, and you enable the patch    Open4All_RP + .
