[GUIDA] Backup EFS + Restore

PER LA GUIDA AL BACKUP CON LA VERSIONE 2.0.23 CLICCATE QUI



Eccomi qua, di nuovo, per presentarvi un tool davvero interessante e molto molto utile che ci farà finalmente fare sonni tranquilli..
Si chiama Backup EFS Pro.
Ho seguito questo THREAD su XDA sin dai primi post in attesa di una release definitiva poi l ho perso di vista causa impegni, motivo per cui ringrazio l' utente "csrurt" per avermi segnalato la disponibilità del download di questo fantastico metodo di backup della nostra cartella EFS.


NOTA: i link di download non sono collegabili direttamente a me e sono quelli originali postati dall autore nel thread di XDA. Il motivo è semplice (ed è una mia decisione), sebbene non sia espressamente richiesto in questo preciso thread, gli sviluppatori tendono a non volere dei mirror per i loro dawnload in modo da poter sfruttare per un motivo o l altro solo il loro.
Pertanto, se il link non dovesse funzionare i motivi potrebbero essere due: problema effettivo al link, oppure aggiornamento ad una nuova versione (la versione precedente viene rimossa, quindi non risulterà accessebile).
Vi chiedo quindi in caso riscontriate problemi di segnalarli subito in questo thread, e se avete urgentemente bisogno del tool scaricatelo da XDA in attesa che venga ripristinato o sistemato qua.
Grazie..

Changelog delle versioni:

EFS Pro v2.0.23
-----------------------
1. Fixed a critical issue which caused EFS Pro to crash on startup when a device was not connected and an emulator was present.

2. Added a filter to the ADB framework code to prevent any emulators from being added to the list of connected devices which avoids some major issues and null reference exceptions.

3. Added a check on startup to prompt and automatically terminate any existing adb processes running on the clients PC to improve application stability.

4. Rolled back source code to .NET Framework v4.0 from v4.5 due to incompatibility with Windows XP.

5. EFS Pro now once again supports 32bit and 64bit OS platforms.


EFS Pro v2.0.20
-----------------------
1. Fixed an issue where Perm Root failed to detect correctly with Rooted Kernels.

2. Fixed an issue where having Corsair Link Dashboard software installed caused a conflict with ADB causing EFS Pro to fail on startup.

3. Updated application source to .NET Framework 4.5 and recompiled in Visual Studio 2012 as a 32-bit application.

4. Fixed a few other minor bugs.


EFS Pro v2.0.17
-----------------------
1. Fixed an issue with the BuildPropertyParser where setting a property failed because of a bug with its root detection.

2. Fixed the manual USB switching feature on the Qualcomm tab caused by the BuildPropertyParser issue above.

3. Fixed the automatic USB switching feature on the Qualcomm tab failing to trigger when launching Qualcomm NV Tools.

4. Fixed an issue in the device partition filter parser that caused the partition list to populate with the missing BusyBox applet error.

5. Changed the startup sequence of EFS Professional. The application now loads instantly and initializes the ADB server and checks the device.

6. Removed toast notification popups.


EFS Pro v2.0.15
-----------------------
1. Fixed an issue that was introduced in the previous version that would exit the application if NO Root permissions were detected. Now only the Qualcomm tab will be available if the connected device does not have Root permissions.

2. Fixed a long standing bug in the ADB Framework's BuildPropertyParser that caused the device to be queried each time a build property was read. As a direct result, functions that involve reading build properties such as the Device Info function are now much quicker!

3. Changed the method of command execution of the NV Backup and NV Restore functions for US Device variants. Direct ADB command line options are now used instead of running the required commands through an ADB Shell. This was done to eliminate the Root permissions requirement that was needed for ADB Shell.

TUTTI I CREDITI VANNO ALL' AUTORE DI QUESTO TOOL: LYRIQUIDPERFECTION

LINK AL PROFILO DI XDA, SE VOLETE POTETE OFFRIRGLI UN CAFFE'

GUIDA ALL' UTILIZZO BY ME, LOL:


Ecco una piccola spiegazione su come si utilizza (anche se è davvero molto semplice) derivata dal mio test.
Specifico che ho su l' ultima MIUI di Angelom in questo momento e ho utilizzato un PC con Windows 7 a 64 bit.

Scaricate il tool dal link diretto qui sopra, aprite il file .zip e trascinate sul desktop la cartella ADB e l' eseguibile "EFS Pro".
Se non avete il Microsoft. NET Framework 4.0 sul vostro PC installatelo da QUI.
Aprite la cartella "ADB" e fate doppio clic sull' exe che trovate al suo interno.
Apparirà una finestra nera con delle righe che scorrono e poi scomparirà, TUTTO NORMALE.
A questo punto assicuratevi di aver il cellulare collegato al PC in modalità Debug USB (Impostazioni -> Applicazioni -> Sviluppo -> Debug USB)
Fate partire "EFS Pro" e date "OK" nella finestra che compare.
Se tutto è andato come deve, vi ritroverete con una finestra davanti con uno spazione nero all interno del quale trovate le informazioni sul vostro terminale.
Adesso è tutto molto intuitivo.

BACKUP EFS:

Possiamo scegliere di fare backup un file .img o .tar e di salvarlo solo sulla sd card, solo sul PC o su entrambi.
Quando avete scelto cliccate su "Backup EFS", in poco tempo il backup sarà completato.

Queste le dimesioni che normalmente dovreste avere: File .img: 20.971.520 byte o 20.480 KB se preferite.
File .tar: 5.275.648 byte o 5.149 KB..
Non preoccupatevi se la differenza è minima, è possibile che i byte non siano precisamente identici.

RESTORE:

Aprite il tool.
Il programma riconosce automaticamente la presenza di backup effettuati precedentemente, sia sul PC che sul device, sia .img che .tar.
Scegliamo che tipo di backup vogliamo utilizzare e da dove prenderlo (PC o device) e clicchiamo su "Restore EFS".
Dopo diverse scritte verdi vi comparirà a video "EFS Restore Success!" e il device sarà riavviato.

Avete finito!

ATTENZIONE: NE IO, NE IL BLOG, NE L AUTORE DEL TOOL, NE LA ME NONNA SIAMO RESPONSABILI DI DANNI E/O PROBLEMI CAUSATI DA QUESTO PROGRAMMA AL VOSTRO TELEFONO O AL VOSTRO
PC.

-----------------------
1. Re-enabled Qualcomm device detection again. If the 'nv_data.bin' file is not present in the efs directory then its usually safe to assume its a Qualcomm device.

2. Added a Debug tab to help troubleshoot problems and crashes etc. To enable it, create a file with the text: 'enable_debug_mode' (without quotes) and save as 'efspro.cfg' in the same directory as the application executable then restart EFS Professional if you already have it running.

3. Changed the way Root permissions are detected. Root permissions are now only checked once when EFS Professional starts rather than when using each function.

4. Updated ADB to latest from Platform Tools R16.

5. A couple more bug fixes have been added.


EFS Pro v2.0.12
-----------------------

vero non avevo letto.

Esiste anche supermanager che è gratuito....


Inviato dal mio GT-I9100 usando Androidiani App

va be piu o meno i file manager sono tutti uguali.

Nelle prove che ho fatto io con il terzo metodo si riesce a vedere la cartella anche dall Archivio, tuttavia ho preferito consigliare un filemanager perchè talvolta potrebbe succedere che tramite archivio non si veda la cartella o non tutti i file; detto questo, potete utilizzare quello che preferite anche perchè ho scritto che io ho usato Astro per i miei test, ma l ho scritto tra parentesi, quindi come requisito vale solo il fatto che serve un file manager, usate quello che preferite!
