Rappel : Vous êtes tenu pour seul responsable de vos actions en suivant ces étapes.

Pré-requis :

Mediatek Smart Phone Flash Tool
Le fichier Scatter "MT6737M_Android_scatter.txt" copier/coller le contenu en bas de page dans le Bloc-note et enregistrer le fichier
Notepad++
Ext2Read (ext2explore)

Télécharger la dernière version de Mediatek Smart Phone Flash Tool
Ouvrir SPFlashTool
Ouvrir le fichier Scatter (contenu en bas de page)
Déselectionner TOUTES les cases

Aller dans l'onglet "Readback"
Maintenant la partie longue, fastidieuse MAIS importante
- Ouvrir le fichier Scatter.txt avec Notepad++
- Parcourer le fichier :

...

- partition_index: SYS23

  partition_name: userdata      <--------- Nom de la partition (Données de l'utilisateur du A55HEU dans ce cas)

  file_name: userdata.img      <--------- Nom du fichier

  is_download: true

  type: EXT4_IMG

  linear_start_addr: 0xe4000000

  physical_start_addr: 0xe4000000     <--------- Adresse de départ de la partition (en hexadécimal)

  partition_size: 0x60000000     <--------- Taille de la partition (en hexadécimal)

  region: EMMC_USER

  storage: HW_STORAGE_EMMC

  boundary_check: true

  is_reserved: false

  operation_type: UPDATE

  empty_boot_needed: false

  reserve: 0x00

...

Dans l'onglet "Readback" appuyer sur "Add"
Une ligne apparait, double cliquer dessus
Enregistrer dans un dossier avec le nom du fichier ex: userdata.img (cf le fichier Scatter.txt)
Dans "Start Adress" écrire l'adresse de départ
Dans "Length" écrire la taille de la partition
Cliquer sur "Ok"

Vous pouvez faire un Dump (Backup/Sauvegarde) complet du téléphone MAIS il faut refaire la manipulation "Add" pour CHAQUE partitions présentes dans le fichier Scatter.txt (environ 23 fois), les partitions SYS24 et SYS25 ne sont pas lisible.

Passons à la lecture :
- A55HEU éteint NON brancher au PC
- Cliquer sur "Read Back" (Flèche verte)
- Brancher l'A55HEU
- Patienter jusqu'à la fin du téléchargement

Il est souvent possible de lire le contenu du fichier "xxx.img" à l'aide de Ext2Read (ext2explore)
