iPhone 7 Wi-Fi Not Working, the <\/span><\/span>Wi-Fi <\/span><\/span>option can not be turned on in <\/span>Wi-Fi <\/span><\/span>settings.<\/span><\/p>\n

And the screen gets stuck when checking the <\/span>Wi-Fi <\/span><\/span>address in the general option.<\/span><\/p>\n

For the iPhone 7 Wi-Fi Not Working issue. Because the <\/span>Wi-Fi <\/span><\/span>could not be turned on, we have to check the working conditions for the <\/span>Wi-Fi <\/span><\/span>chip. <\/span><\/p>\n

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

First, check the reset signal line on R0806, the diode value is 374, which is normal.<\/span><\/p>\n

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

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

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

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

Then measure the voltage values on C7602, C1605, L7600_RF, the measured values are 4.15V, 1.79V, and 1.34V, all of them are normal.<\/span><\/p>\n

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

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

Then remove the <\/span>Wi-Fi <\/span><\/span>chip and checked the diode values on the pads. After checking, all of the values are normal. So we can conclude that the <\/span>Wi-Fi <\/span><\/span>chip should be broken, then get the <\/span>Wi-Fi <\/span><\/span>chip replaced with a new one.<\/span><\/p>\n

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

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

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

For iPhone 7, there’s some encrypted connection between the Wi-Fi chip and NAND, so we will need to <\/span>desvincular <\/span><\/span>the connection between the <\/span>Wi-Fi and the NAND.<\/span><\/span><\/p>\n

The previous unbinding method is we should remove the NAND, then put into the NAND chip into NAND programmer to unbind. After that, solder back the NAND to the motherboard.<\/span><\/p>\n

\"\" \"\"<\/span><\/p>\n

\"\"  \"\"<\/span><\/p>\n

(WL programmer and relevant software as above)<\/span><\/p>\n

\n

And by now, other more convenient methods are introduced. <\/span><\/p>\n

For example, if the motherboard can be connected with a computer, then we can unbind the connection between Wi-Fi and NAND with a programmer like the iRepair P10<\/a><\/span> <\/span><\/a><\/p>\n

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

After finish unbinding, replace another <\/span>Wi-Fi module <\/span><\/span>and tested again, the <\/span>Wi-Fi <\/span><\/span>option could be turned on, and the <\/span>Wi-Fi <\/span><\/span>function was back to normal, problem resolved.<\/span><\/p>\n

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

Consejos: <\/span><\/b>For iPhone 6s and above models, the <\/span>Wi-Fi <\/span><\/span>module is bundled with the NAND flash chip. <\/span><\/p>\n

We should unbind the connection between the NAND and Wi-Fi chip with the relevant programmer.<\/span><\/p>\n
