Nokia C2 03 C2 06 C2 08 Memory Not Detected Solution MMC IC Jumper Tracks Ways
Heres another solution that covers for Nokia C2-03, C2-06, C2-08 memory card not detected problem cause by wet damaged or any possible causes like oxidation build ups etc.The Nokia C2-03, C2-06 and C2-08 slider phone has designed with a built in ESD and EMI filter chip that protects the system circuit if theres something went wrong from the memory card. In most Nokia PCB design this chips were also found and called as "MMC filter IC". So, in troubleshooting Memory card not detected problem mostly it can be fix by replacing the said MMC IC.
Heres some hints on how to fix Nokia C2-03, Nokia C2-06 or Nokia C2-08 Dual SIM card, slider phone with touch and type features.
1) If memory card is not detected error shows, try to use another working memory card. The memory card might be corrupt or already damaged.
2) Check for possible damaged and or clean the memory card connector pins and its surroundings components on the PCB board.
3) Check the firmware, reflash, restore or update to latest version if necessary.
4) Check, resolder, rework or replace the memory card filter chip (MMC filter IC)

Nokia C2 03 C2 06 C2 08 Not Charging Problem Solution
Now working on with the new solution for Nokia C2-03, C2-06 and C2-08 with Dual SIM phone capability. This time we will tackle first the charging circuit in case handling into troubleshooting a not charging problem, due to wet damaged or any possible causes.
The highlighted components below are the basic components of Nokia C2-03, C2-06 and C2-08 charging circuit just like any other Nokia previous PCB designs, the only thing always makes any different is the location of those particular components location being mounted on the PCB board.
And heres how to fix a not charging problem for Nokia C2-03, C2-06 and C2-08:
1) Ensure and check first the wall charger, battery and battery connectors for possible damaged.
2) Check the charging pin connector (DC jack), clean it including the terminal contact pads. Replace if necessary.
3) Check the charger voltage protection components such as the fuse, diode, filter coil and capacitors. Replace if found damaged.
4) Trace the charger voltage line paths for possible open circuit or cut-off lines.
5) Check the charging voltage transistor switching circuits, including the 0.15 ohms fusible resistor.
