我刚按入"*#06#" 进行 全部 自检 发现我的五维导航键 的向下,左右三个方向失灵了,
其他正常。而我以前一直是好的。我推断是在移动营业厅里面的维修点弄坏的,因为这个
小年轻当我面的时候拆我手机就是野蛮用力(当时就把手机拿回才对),BEN的不会开M65外壳,拿到手机后我仔细看
,发现闪光灯处的塑料外壳已经被损坏。
我在网上搜索 M65 "card error"找到如下资料,大意是“手机插不插SIM卡都提示 CARD
ERROR”建议是
第1:查看Shematics并换掉 ESD-Protection Diode (V1605) , PullUp Resistor R1614
(4,7K VDD_SIM -> SIM_I/O) and C1606 (18pF)
这是从M65电路图得来的。
第2:如果还没好的话,把S-Gold, RAM and Flash重新焊一下
第3:如果还没好的话 SRAM或S-GOLD,或者都换掉。
i have two phones with this problem, sl65 and c65, i power on without sim
card, says this messagesim card error)with the sim card inserted locks in logo
startup, full flash dont solves, believe i be an hardware problem, can anybody
help me??
thanks!!!!
He wrote, he gets the message SIM Card Error WITHOUT a SIM is inserted.....
Cleaning the SIM Card and ensuring the connection doesent match......
Open connections cant couse an error if no SIM is inserted...
Sonds like damaged HW like S-Gold, RAM, or some wrong Signal-Levels on CC I/O
(ChipCard Input/Output) or CC RST (ChipCardReSeT).
1st : Look in Shematics and try to exchange the ESD-Protection Diode (V1605) ,
PullUp Resistor R1614 (4,7K VDD_SIM -> SIM_I/O) and C1606 (18pF) this can
couse such an error, but not the only possibility. (This are from M65 Diagramm
- but values of those parts the same, maybe they have other names)..
2.nd : if this does not function, try to rehot S-Gold, RAM and Flash.
3.rd : If not works, exchange SRAM and/or S-GOLD or both... |
