Fen\u00f3meno del mal funcionamiento<\/span><\/b><\/p>\n

El iPhone 7 se atasc\u00f3 en el modo de recuperaci\u00f3n, y report\u00f3 el c\u00f3digo de error 9 al restaurar con iTunes. <\/span><\/p>\n

Soluci\u00f3n de problemas<\/span><\/b><\/p>\n

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

Seg\u00fan la experiencia en reparaciones, el c\u00f3digo de error 9 suele estar causado por el mal funcionamiento de la flash NAND U1701 o la EEPROM U2301. <\/span><\/p>\n

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

W<\/span><\/span>e comprob\u00f3 la NAND midiendo el voltaje en C1721, C1702, y C1730, el valor era 3.0V, 0.9V, y 1.8V, que eran normales. <\/span><\/p>\n

\"\"  \"\"  \"\"<\/span><\/p>\n

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

A continuaci\u00f3n, siga comprobando la alimentaci\u00f3n de la EEPROM midiendo la tensi\u00f3n en C1101. <\/span><\/p>\n

El valor era de 1,8 V, tambi\u00e9n normal. <\/span><\/p>\n

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

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

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

T<\/span><\/span>a alimentaci\u00f3n de la NAND y la EEPROM eran normales, el problema podr\u00eda venir de la l\u00ednea de datos o de los chips. Quitamos la NAND y comprobamos los pads de la PCB, todos los valores de los diodos <\/span>tambi\u00e9n son <\/span><\/span>normal, <\/span>a continuaci\u00f3n, utilice el<\/span><\/span> Lector de NAND para comprobar el chip NAND, tambi\u00e9n era bueno.<\/span><\/p>\n

As\u00ed que<\/span><\/span> nosotros <\/span>puede probar <\/span><\/span>para sustituir otra EEPROM U2301.<\/span><\/p>\n

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

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

En <\/span>sustituci\u00f3n de<\/span><\/span> otra EEPROM, <\/span>conecte<\/span><\/span> con el ordenador, e intent\u00e9 restaurar de nuevo, ya no hab\u00eda c\u00f3digo de error y el tel\u00e9fono funcionaba con normalidad. <\/span><\/p>\n
