L'iPhone 7 est rest\u00e9 bloqu\u00e9 en mode de r\u00e9cup\u00e9ration et a signal\u00e9 le code d'erreur 9 lors de la restauration avec iTunes. <\/span><\/p>\n

<\/span><\/b><\/p>\n

D'apr\u00e8s l'exp\u00e9rience des r\u00e9parateurs, le code d'erreur 9 est g\u00e9n\u00e9ralement d\u00fb \u00e0 un dysfonctionnement de la m\u00e9moire flash NAND U1701 ou de la m\u00e9moire EEPROM U2301. <\/span><\/p>\n

<\/span><\/p>\n

W<\/span><\/span>Nous avons v\u00e9rifi\u00e9 la NAND en mesurant la tension sur C1721, C1702 et C1730. La valeur \u00e9tait de 3,0V, 0,9V et 1,8V, ce qui \u00e9tait normal. <\/span><\/p>\n

<\/span><\/p>\n

Ensuite, continuez \u00e0 v\u00e9rifier l'alimentation de l'EEPROM en mesurant la tension sur C1101. <\/span><\/p>\n

La valeur \u00e9tait de 1,8 V, ce qui \u00e9tait \u00e9galement normal. <\/span><\/p>\n

<\/span><\/p>\n

<\/span><\/p>\n

T<\/span><\/span>L'alimentation de la NAND et de l'EEPROM \u00e9tait normale, le probl\u00e8me pouvait provenir de la ligne de donn\u00e9es ou des puces. Nous avons retir\u00e9 la NAND et v\u00e9rifi\u00e9 les pads sur le PCB, toutes les valeurs des diodes ont \u00e9t\u00e9 v\u00e9rifi\u00e9es. <\/span>sont \u00e9galement <\/span><\/span>normale, <\/span>puis utiliser le<\/span><\/span> Le lecteur NAND pour v\u00e9rifier la puce NAND, il \u00e9tait \u00e9galement bon.<\/span><\/p>\n
